The transportation sector is one of the biggest reasons why the average temperature on our planet is climbing, a phenomenon you probably know as climate change. In the United States, transportation contributes about a third of the carbon dioxide, or CO2, that the country releases into the atmosphere where it traps heat and causes temperatures to rise. Every year, Americans produce about 1.9 billion metric tons of carbon dioxide from driving cars, flying in planes, and shipping things by road, sea, rail, and air all over the country. That’s the weight of more than 20,000 Washington Monuments.

https://grist.files.wordpress.com/2020/03/transportation-1.jpg

We want to get that 1.9 billion number closer to zero as soon as possible. But we still need ways to get people and products from one part of the country to another. How do we change the way we move ourselves and our things so that we create fewer planet-warming emissions?

Grist has put together some introductory videos and activities to help you understand some of the ways the transportation sector might go green.

Electric Cars

Electric vehicles are an exciting alternative to the traditional, gas-guzzling, combustion-powered cars. Instead of filling up at the gas station, you simply plug your car into an electric socket and charge the car’s battery. In the past decade, electric cars have gotten better, cheaper, and more popular.

So is an electric car right for your family? It all depends on where you live, how you gets around, and what your family can afford.

Activities:

Research: Look up and see if there are electric vehicle charging stations in your area. If you live in an area where there are very few charging stations, it might be difficult to imagine owning an electric car. Think about all the car trips you normally make: school, work, grocery shopping, even weekend trips and vacations. If your electric car could go 100 miles on a charge, could you still easily make most of these trips?

Do: The “greenness” of your electric vehicle depends on how your region generates electricity. You can find out by typing your ZIP code into the “power profiler” sidebar on this Environmental Protection Agency web page. It will tell you how many pounds of carbon dioxide it takes to produce a megawatt-hour of electricity — the energy equivalent of about 28 gallons of gasoline. We can use this number to compare whether an electric car is better than a gas car in your city.

For our comparison, we’re going to use a 2020 Honda Civic as our gas-powered car, and a 2020 Nissan Leaf as our electric car.

https://grist.files.wordpress.com/2020/03/math6.png?w=1200
So … which car produces more CO2 in your city?
Discuss: Would an electric car work with your family’s budget and driving habits? Why or why not?

Walkable Cities

Have you ever gotten in the car only to drive a few blocks away? You’re not alone. Americans take a lot of unnecessary car trips. If we could get more people to take the bus, hop on a bike, or simply walk more, we could shave off a big chunk of the U.S.’s transportation-related emissions.

Some neighborhoods are less walkable than others. If you live near a busy road or in a neighborhood far from your favorite hangouts, it can be inconvenient or even dangerous to walk. To get more people out of their cars and walking, we need to think about how our neighborhoods are designed.

Activities:

Research: Look up your address on the Walk Score website. This will give you a ranking based on how easy it is to walk to nearby stores, schools, or parks. If you click “About your score,” you can see which categories your home scores low and high on.

What’s your score? Do you agree with this assessment? Why or why not?

Discuss: Think about all the places you go on a regular basis. Where do you shop for groceries, eat food, or watch movies? What parks do you like to visit? Can you find any alternate places to do these activities that are within walking distance?

Bikes

Bikes are fun, healthy, and climate-friendly forms of transportation. But not everyone owns a bike — or it can be impractical to lug one along for certain types of trips. In some cities, companies offer bikes on the sidewalk that you can just hop on and ride.

Activities:

Research: How does the built environment make people more or less likely to bike? Look up your neighborhood’s Bike Score. This tool grades each neighborhood’s bike-ability based on four factors: safe infrastructure (like bike lanes), hills, the number of gathering places within biking distance, and how many of your neighbors also ride bikes.

Observe: Does your neighborhood have bike lanes? Would you feel safe riding a bike in your neighborhood? How many of your favorite destinations — like parks, restaurants, stores, or museums — are within biking distance? Does your neighborhood have a lot of hills? If it does, would a rentable e-bike make you more likely to ride? The Bike Score website believes that it’s safer to ride on streets that have a lot of bike traffic already. Do you see people riding bikes in your neighborhood?

Discuss: Does your city have a bikeshare or short-term rental program? What are some trips you would take using a bike you own or could rent?

Do: Plan a fun fantasy trip you could take on a bike. Where would you want to go? What would you need to bring? How much time would you need?

Trains

Trains have been around for nearly two centuries, and they’re a promising solution for cutting the country’s transportation emissions. They’re also pretty efficient — meaning they only use a little bit of fuel to carry each rider. Some trains even run on electricity.

But in the United States, our trains are pretty slow and outdated. Can we fix them?

Activities:

Research: Think about the most recent plane trips you have taken. Would it have been possible to take the train instead? How much time would it take? How much would it cost?

Discuss: What might make you want to take a train over a plane? How would you make a train trip a more desirable option compared to an airplane flight?

Beyond lithium-ion technology, graphene can enhance the performance of next generation lithium-sulphur batteries. The battery promises lower costs due to the use of widely available sulphur as the cathode. Combined with a lithium metal anode and improvements to specific energy (Wh/kg) have also been achieved. Unfortunately, there are similarities between silicon and sulphur in that sulphur is also prone to stability issues – polysulphides tend to dissolve and diffuse to the anode where they react and cause a loss of active material. Furthermore, sulphur is not conductive and also expands during lithiation, though not to the extremes of silicon, and so requires both conductive additives and space within the electrode for the sulphur to expand into. Norwegian start-up Graphene Batteries employ a graphene network which provides a conductive network, space for volume expansion and may also help to trap polysulphides from diffusing to the anode. Nevertheless, the lithium-sulphur chemistry is still at the very early stages of commercialisation with various performance parameters needing to be improved upon and demonstrated.

The highly specific surface area and conductivity of graphene meant its first application in energy storage, that gained traction, was not in batteries but supercapacitors (capacitance is directly proportional to surface area). The theoretical specific capacitance of a single graphene layer is 550 F/g, 3-4 times the capacitance achieved from activated carbon in organic electrolyte (the incumbent electrode material). Companies are exploring μF chips through to kF modules for IoT devices through to wind turbines and off-road vehicles. All are looking at different ways to cost-effectively incorporate graphene without re-stacking or by appropriately modifying the surface. Unfortunately, the use of graphene has so far resulted in minimal improvements to specific capacitance or energy density. Graphene has been able to further improve power density but given power and fast charge/discharge capability are already strengths of supercapacitors, it is unlikely to unlock significant new markets.

Graphene can help enable lithium-sulphur technology and improve supercapacitor performance but IDTechEx believe they are most likely to occupy niche positions in the energy storage market, see “Advanced Li-ion & Beyond Li-ion Batteries 2018-2028”. Li-ion technology is set to dominate over the coming decade and here, graphene can play an important role. Analysts at UK-based market research company, IDTechEx, cover various aspects of the energy storage and graphene markets, assessing the trends, bottlenecks and market potential of new materials and technologies. The newly updated report “Li-ion Batteries 2020-2030” provides a comprehensive view of the Li-ion market and the opportunities for new materials, while the report “Graphene, 2D Materials and Carbon Nanotubes 2019-2029” provides detailed analysis of the titled materials, their commercial progress and their prospects moving forward.

It would be wrong to say that wireless charging systems are more efficient today than wired systems. Even in wireless charging systems, the phone needs to touch a device, but there are a lot of waves moving in the air, and MIT researchers are working on a project where we can use the wasted energy to charge our devices.

Terahertz radiation consists of high-frequency waves in the electromagnetic spectrum between infrared and microwaves. These waves are produced by devices that send Wi-Fi signals. Although these irradiations are very difficult to use, the new method the MIT team has found seems interesting.

Working principle of the device:
It is worth noting that at this stage the system is still in the project phase and has not been tested yet. “We are surrounded by electromagnetic waves in the frequency range of Terahertz radiation. If we turn this energy into an energy that we can use in everyday life, it helps us fight the energy problems we face,” said Hiroki Isobe, one of the scientists who led the study.

The device produced by the team is known as a terahertz rectifier and consists of a small graphene layer with a boron nitride layer underneath and an antenna on both sides. These antennas collect terahertz waves from the air in the environment and strengthen the signals passing to the graphene. These allow electrons to flow in the same direction and generate direct current. Graphene must be as pure as possible, as any foreign matter will affect electron scattering, the team said. Boron nitride layer is also used to prevent this.

Although Terahertz rectifier produces a small amount of energy at first, it may be enough to charge small devices. The team first states that this device can be used in pacemakers. This device, which may have good results for wireless charging, is expected to be manufactured and tested.

Gratomic $GRAT.ca Receives Notice to Grant Mining License $SRG.ca $NGC.ca $LLG.ca $GPH.ca $NOU.ca #TODAQ

Posted by AGORACOM at 2:13 PM on Thursday, March 26th, 2020
  • Ministry of Mines is prepared to grant Mining License 215 (ML215) for its Aukam Graphite Property in Namibia.
  • Gratomic can now produce a concentrate of up to 98% Cg
  • Management has subsequently decided to build a 20 000 tonne per annum processing plant.

Gratomic Inc. is pleased to announce, supplementary to its February 21, 2020 Press Release, that it has received a Notice from the Ministry of Mines and Energy of Namibia that the Minister is prepared to grant Mining License 215 (ML215) for its Aukam Graphite Property in Namibia. The License area falls within the proximity of the Aukam Processing Plant and the Graphite bearing shear zone for a total of 5002 hectares (5002 ha). Securing the mining license is a critical step towards moving the Aukam Mine into commercial production.

The Company has completed 8 months of pilot testing on historically mined product and conducted an internal study on the efficiency of the pilot processing facility on this material. Through rigorous testing and adjustments to the plant, Gratomic can now produce a concentrate of up to 98% Cg. Management has subsequently decided to build a 20 000 tonne per annum processing plant. To date, 90% of construction is complete. Upon completion of the remaining 10%, the Company will initially start processing material from historical workings left at the surface when the mine last operated in 1974.

The Company has recently appointed Dr. Ian Flint to complete a preliminary economic assessment on the Aukam Processing plant. The study, its recommendations, and their subsequent implementation, will ensure the scale up of the existing pilot plant to a commercial scale processing facility that will provide the desired concentrate grades and production rates.

With respect to site exploration, in the coming months diamond drilling will resume at Aukam Graphite. The drilling will be conducted utilizing Company owned drilling equipment, focusing on areas proximal to graphite mineralization, depicted by previous diamond drilling, underground excavation and surface outcrop sampling. The drill targeting will be systematic with the expectation of producing an NI 43-101 resource estimate.

Arno Brand, President and CEO of the Company stated that “the Company will be able to satisfy all of the conditions in the Notice and proceed to commercialization of its Aukam Graphite Mine. This marks a significant milestone for the Company.”

Risk Factors

No mineral resources, let alone mineral reserves demonstrating economic viability and technical feasibility, have been delineated on the Aukam Property. The Company is not in a position to demonstrate or disclose any capital and/or operating costs that may be associated with the processing plant.

The Company advises that it has not based its production decision on even the existence of mineral resources let alone on a feasibility study of mineral reserves, demonstrating economic and technical viability, and, as a result, there may be an increased uncertainty of achieving any particular level of recovery of minerals or the cost of such recovery, including increased risks associated with developing a commercially mineable deposit.

Historically, such projects have a much higher risk of economic and technical failure. There is no guarantee that production will begin as anticipated or at all or that anticipated production costs will be achieved.

Failure to commence production would have a material adverse impact on the Company’s ability to generate revenue and cash flow to fund operations. Failure to achieve the anticipated production costs would have a material adverse impact on the Company’s cash flow and future profitability.

Steve Gray, P. Geo. has reviewed and approved the scientific and technical information in this press release and is the Company’s “Qualified Person” as defined by National Instrument 43-101 – Standards of Disclosure for Mineral Projects.

About Gratomic Inc.

Gratomic is an advanced materials company focused on mine to market commercialization of graphite products most notably high value graphene-based components for a range of mass market products. We have a Joint Venture collaboration with Perpetuus Carbon Technology, a leading European manufacturer of graphenes, to use Aukam graphite to manufacture graphene products for commercialization on an industrial scale. The Company is listed on the TSX Venture Exchange under the symbol GRAT.

Sutherland Avenue in the City of Westminster now has 24 streetlamp charging posts to top up electric vehicles overnight

Research conducted by Siemens found that over a third of British motorists are planning to buy into an electric future by purchasing a hybrid or full electric vehicle as their next car, with 40 percent saying that they would have jumped in sooner if the charging infrastructure was better.

In London, drivers believe that only 100 to 200 charging points are available in total, and many think that it’s just not possible to juice up an EV at home or at work. Berlin-based Ubitricity has been converting streetlamps to charging points in the UK’s capital since 2015, and together with project partner Siemens now have some 1,300 installations dotted throughout the city.  

A cable featuring a smart meter is plugged into the electric vehicle and streetlamp for overnight charging Siemens

The technology is installed in existing streetlamp columns, and uses already-available infrastructure, so there’s no digging up roads to lay new cables. Electric vehicle users plug a SmartCable into the streetlamp column and the other end is connected to the vehicle, allowing battery-electric and plug-in hybrid vehicles to charge overnight outside residences that don’t have driveways or garages. An in-cable meter box registers how many kilowatt-hours are used and the customer is billed accordingly.

The City of Westminster has a total of 296 streetlamp charging points in service, but Sutherland Avenue is reported to be the first residential avenue in the UK to have full conversion of its steetlamps. And the two adjoining roads are due to be converted in the coming weeks too. The city council is looking to have a thousand charging points in the inner London borough within the next year.

“In a city that suffers from some of the worst air pollution in the country, we need to be supporting the change to green technology as much as we can,” said Councilor Andrew Smith. “Electric Avenue, W9 gives us a glimpse into the future of streets in Westminster, where we hope to provide the infrastructure needed for our residents to make the switch to cleaner, greener transport.”

  • Nonprofit promotes documentary made by Tigard man, Ryan Hunter; it’s called ‘Electrified – The Current State of Electric Vehicles’

For most college students, adding more work to their plate sounds like a nightmare.

They spend long nights and early mornings focusing on their studies. But for University of Portland sophomore Ryan Hunter, directing his first documentary seemed like a fun challenge.

The movie, “Electrified — The Current State of Electric Vehicles,” brings together electric vehicle owners and industry professionals to break down misconceptions about the specialized cars. It’s now being promoted by nonprofits like Plug In America and Forth.

“The whole point of this movie was to explain some of the common things that people should know when getting an electric car and tell them some important things to consider before getting one,” said Hunter. “My main goal is to lead people to buy an electric car based on some of the stuff they learn from this film.”

Hunter started making the film last July. He became interested in the topic because he was thinking about buying an electric vehicle. He started looking into some of the high-tech features, such as Tesla’s autopilot hardware.

Tesla is an American company that specializes in electric vehicle manufacturing and battery energy storage.

From that beginning, Hunter decided to put his self-taught filmmaking skills to good use.

“It started off with just interviewing a couple of people who I know own electric cars,” Hunter said. “But as I started interviewing people and talking to more people, I was able to get connections to (Forth) in Portland. … And that kind of shifted the idea of a film from just owners’ impressions to also having these expert opinions dragging the narrative of the film.”

Zach Henkin, Forth’s deputy director, was happy to help Hunter once he learned about the film. The Portland-based nonprofit consults with cities, utilities and automakers to promote electric vehicles and shared transportation.“We’re seeing this as another way that we can continue to get the word out for folks who are curious or interested and want to know what’s going on with all these cars that don’t need gas,” Henkin said.

Forth is promoting the film through social media and newsletters. The nonprofit is considering hosting a screening of the movie to get the word out.

One of the biggest challenges is letting people know the benefits of electric vehicles, Henkin said.

“These cars are just simply better cars,” he said. “You can get tax credits from the (federal government), and you can get cash from the state. They’re also inexpensive, and you don’t have to pay gas.”

Henkin appreciates Hunter taking the time to research and inform others through a documentary. At the time of the interview, Henkin didn’t know Hunter’s age, and he was surprised to discover that the young director had an interest in the topic.

“It’s really telling about what we’re seeing with younger generations,” Henkin added. “They’re latching on to topics that are important (and) might not be getting the amount of attention that they could be.” He concluded, “It makes me wonder how maybe older generations, myself included, are approaching similar things and maybe missing stuff.”

Henkin hopes Hunter can leverage the documentary to bigger and better things. As for Hunter, he has other dreams.

“Computer science is kind of more of a thing I’d like to make a career out of,” he said. “But filmmaking is definitely something I like to do in my free time.”

Hunter remembers making short videos at 13 and having an overall interest in the craft.

“I took a filmmaking class in high school, but (it) was very basic, so it wasn’t a lot that contributed to my knowledge,” said Hunter, who graduated from Southridge High School in Beaverton two years ago. “Everything I know has been self-taught.”

Hunter doesn’t know if he’ll continue making films in the future, but he already is thinking about a possible sequel to his first documentary.

“People said that they’d love to see a follow-up to this where I look to see where electric cars are in a couple of years, because there are more changes that are coming,” Hunter said.

He expects the price of electric vehicles to continue going down. A market once dominated by Tesla and other luxury brands is now increasingly populated with somewhat less expensive models, like the Nissan Leaf and the Fiat 500e. As more and cheaper electric cars are introduced, Hunter said, that growing market will make owning an electric vehicle “more accessible to much more people than it currently is now.”

Despite having no intentions for his film to “make it big,” Hunter is glad his movie is helping others make informed decisions.

“If just one person gets an electric vehicle based on this movie, I would say that’s a win,” Hunter said. “Any change that I can help make with the environment is good.”

As for what Hunter learned from the film, he’s planning on getting a Tesla Model 3 — the automaker’s most popular (and affordable) car — in a couple of months.

“Electrified — The Current State of Electric Vehicles” is available to watch on YouTube and Amazon Prime Video

Vehicle-To-Grid Charger Maker Fermata Receives UL Certification SPONSOR: Lomiko Metals $LMR.ca $CJC.ca $SRG.ca $NGC.ca $LLG.ca $GPH.ca $NOU.ca

Fermata’s bidirectional charger (pictured) has been the first to attain UL 9741 certification. Image: Fermata Energy.

An electric vehicle-to-grid (V2G) charging system which allows for bi-directional flows of power created by US maker Fermata Energy, has become the first to receive certification under a new standard introduced by UL.

UL 9741, ‘Investigation for bidirectional electric vehicle charging system equipment’, was first published on 18 March 2014. Almost six years to the day later Fermata – which has previously partnered with automakers including Nissan and received investment from backers such as Japanese utility company TEPCO – became certified under the North American safety standard.

Vehicle-to-grid, allowing parked cars to discharge as well as charge energy to and from the grid from their batteries means they can be used as a grid-balancing resource. Fermata Energy’s website states that the company was founded for two purposes: to accelerate the adoption of EVs and to accelerate the transition to renewable energy. By acting as stationary energy storage systems (ESS), EVs can provide services such as frequency regulation.

Thus far, while V2G technology has existed at least since the early 2000s, and been trialled on a commercial basis in the last five years or so, various barriers exist to widespread adoption. Last year, a research note from consultancy Apricum pointed some of these out, including potential reluctance of owners to allow aggregators access to their batteries, which may have an impact on battery lifetime through causing accelerated degradation of battery cells. Another possible barrier is that trials have only shown very limited commercial revenues being possible for using EV batteries for frequency regulation under most existing market structures.

From the carmakers’ point of view, only a few have given serious thought to enabling the function due to possible impact on warranties, with Nissan being the first to allow its Leaf EV to be used in this way. Earlier this month, Energy-Storage.news reported on a successful V2G ‘showcase’ project where Leaf EV batteries were used for storing locally generated renewable energy.

Despite the barriers that exist, V2G technology is likely to have a “bright future,” Apricum experts Florian Mayr and Stephanie Adam, who co-authored that earlier mentioned piece on the consultancy’s website, said. While acknowledging a survey held in Germany by digital association Bitkom that found only 37% of EV owners would be willing to allow their cars to be used for V2G participation, if one large electric mobility market such as China went for it, others might follow quickly.

“With increasing demand for the required components, standardization will improve and economies of scale will kick in. Due to falling costs for hardware, the economic case for a car owner participating in V2G will improve, increasingly outweighing potential disadvantages of a reduced battery lifetime or limitations in car availability,” the Apricum note said.

Meanwhile, Fermata Energy CEO and founder David Slutzky said that bidirectional energy solutions “play an important role in reducing energy costs, improving grid resilience and combating climate change. We’re excited to be the first company to receive UL 9741 certification and look forward to partnering with other organisations to advance V2G applications.”

VW Appears To Be Eyeing Vehicle-To-Grid Technology, Could Sell Energy From Electric Vehicles SPONSOR: Lomiko Metals $LMR.ca $CJC.ca $SRG.ca $NGC.ca $LLG.ca $GPH.ca $NOU.ca

Volkswagen plans to have millions of electric vehicles on the road by the end of the decade and that opens up new opportunities for the automaker.

According to Reuters, Volkswagen’s chief strategist revealed the company is exploring new business opportunities related to the energy stored in electric vehicles.

As Michael Jost explained, “By 2025, we will have 350 gigawatt hours worth of energy storage at our disposal through our electric car fleet.” He went on to say that number will increase to 1 terawatt hours by the end of 2030.

That’s a massive amount of electricity and Jost noted it’s “more energy than is currently generated by all the hydroelectric power stations in the world.” This opens up a new opportunity for the automaker as Volkswagen can tap into this energy using vehicle-to-grid technology.

Essentially the opposite of charging, vehicle-to-grid technology allows electric vehicles to send energy back to the electrical grid. This would typically occur during times of high demand.

This represents an interesting opportunity for Volkswagen as they could become a makeshift energy company. While Jost didn’t go into too many specifics, it’s not hard to imagine how such a service would work.

In theory, electric vehicles would be charged at night when demand for electricity is low and so are energy rates. When demand and rates increase, Volkswagen vehicles could sell some of that energy back to the grid. Consumers would likely be paid for this, but Volkswagen could potentially take a cut of the profits.

It remains unclear if that is what Volkswagen is thinking, but it could be a potential win-win situation. Consumers would get paid, while energy companies could tap into affordable electricity. Likewise, Volkswagen could get a slice of the action.

There’s no word on when this capability could be added to electric vehicles from Volkswagen, but a number of companies are exploring vehicle-to-grid technology. Nissan has even demonstrated how electric vehicles could be used to power your home in the event of a power outage.

The first demonstration of graphene double quantum dots in which it is possible to control the number of electrons down to zero has been reported in Nano Letters. Far from an abstract academic stunt, the results could prove key to future implementations of quantum computing based on graphene. “Having exact information and control over the number of electrons in the dots is essential for spin based quantum information technology,” says Luca Banszerus, a researcher at RWTH Aachen University in Germany and the first author of the paper reporting these results.

Although this level of control has been demonstrated in single quantum dots, this is the first demonstration in graphene double quantum dots, which are particularly useful as spin qubits. “Using a double dot heavily facilitates the readout of the electron’s spin state and the implementation of quantum gates,” Banszerus adds.

Less edgy quantum dots 

The idea of using graphene in quantum dots dates back almost as far as the first reports of the material’s isolation in 2004. Graphene has almost no spin-orbit interaction and very little hyperfine coupling, which would suggest that spin lifetimes can be extremely high. Unfortunately, quantum dots physically etched from larger graphene flakes run into problems due to the disorder at the dot’s edges disrupting the material’s behavior. As a result, the transport behavior of these quantum dots is dominated by localized states at the edges. “This leads to an unknown effective quantum dot size and an occupation of typically many electrons,” says Banszerus.

Instead, Banszerus and colleagues at RWTH Aachen and the National Institute of Materials Science in Japan work with bilayer graphene, which can be tuned to be a semiconductor. A voltage applied to specific regions of a bilayer graphene flake can switch those regions to behave as insulators, electrostatically defining a quantum dot that has no edge states nearby.

The Aachen researchers strip single flakes of bilayer graphene from graphite (mechanical exfoliation) and handle it using a dry pick-up technique that hinges on van der Waals interactions. They encapsulate the bilayer graphene in hexagonal boron nitride (hBN) crystal. They then place the structure on a graphite flake, which acts as the bottom electrode, and add chromium and gold split gates and finger gates separated from the split gates by a 30-nm-thick layer of atomic layer deposited Al2O3.

They were able to control the number of electrons on the quantum dots by applying a voltage, which also affected the tunneling coupling between the dots. As a result, once the total occupation of the two quantum dots exceeds eight electrons, they begin to behave as one single quantum dot, rather than a double quantum dot. Transport measurements also revealed that the number of electrons loaded on the quantum dot could be controlled down to zero electrons.

The idea of defining quantum dots in bilayer graphene electrostatically in this way is not new. However, although different groups have attempted this approach since 2010, the process required recently discovered tricks of the trade, such as better encapsulation in hBN and the use of graphite flakes as gates to get a clean band gap. Banszerus says these developments came as quite a surprise and revived interest in graphene quantum dots in 2018. He hopes the capabilities they have now demonstrated will further spark activity in this field.

Coupling control

“Even though being able to control the number of charges in a graphene double dot is a huge step forward, there are still many problems to be solved on the road toward spin-based quantum information technology in graphene,” says Banszerus. Next, he hopes to tackle the problem of controlling the coupling between the quantum dots and the reservoir, which he hopes to achieve by adding an additional layer of interdigitated finger gates on top.
