U.S-based graphene flake producer Avadain has announced its new crowdfunding campaign to raise up to $5 million on the NetCapital funding portal.

Avadain says it will use the funds for further upscaling, patenting, samples and operating expenses.

NanoGraf has announced that it won a $1 million development contract from the Department of Defense to produce a more powerful, longer-lasting 4.3Ah lithium-ion battery. The cell will aim to provide U.S. military personnel with enhanced run-time for the equipment they rely on to operate safely and efficiently.

This is the second Department of Defense project won by NanoGraf. In 2021, the company developed the world’s longest-running 3.8Ah 18650 cylindrical lithium-ion cell, at 800 watt-hours per liter (Wh/L). This cell will is meant to go into volume production in the Spring of 2022.

Archer Materials has announced a milestone in the development of its biochip, which is being created to detect various deadly communicable diseases.

The company achieved electronic transport in atom-thin graphene integrated with silicon electronics. Various voltage ranges were repeatedly recorded on the integrated devices when current-voltage traces were performed.

TechBlick is now offering Graphene-Info's readers a special 25% discount towards the upcoming virtual graphene event - Graphene, CNTs and 2D materials - which will take place on April 26-27.

The virtual conferences hosts an impressive speaker lineup, and a wide range of topics, ranging from graphene production to graphene applications, investments and related materials. This is likely to be a great event, and the ticket is actually an annual pass to all of TechBlick's events.

The Rice lab of professor James Tour has modified its flash Joule heating process to produce doped graphene that tailors the material’s properties for optical and electronic devices.

The modified process shows how graphene can be doped with a single element or with pairs or trios of elements. The process was demonstrated with single elements boron, nitrogen, oxygen, phosphorus and sulfur, a two-element combination of boron and nitrogen, and a three-element mix of boron, nitrogen and sulfur.

Researchers from KAUST, Lanzhou University, Xiamen University, Friedrich Schiller University Jena and Ulsan have presented a method to produce single-crystal graphene sheets on large-scale electrically insulating supports. This approach could promote the development of next-generation nanomaterial-based devices, such as light and thin touchscreens, wearable electronics and solar cells.

Most graphene-based electronic devices require insulating supports. Yet, high-quality graphene films destined for industrial use are typically grown on a metal substrate, such as copper foil, before being transferred to an insulating support for device fabrication. This transfer step can introduce impurities that affect how well the device performs. Efforts to grow graphene on insulating supports have thus not been successful in producing the required high-quality single crystals.

Researchers from Berkeley Lab’s Materials Sciences Division and the University of California, Berkeley, in collaboration with scientists at ISPC-CNR and Tsukuba's National Institute for Materials Science, have determined that interactions between electrons give rise to the effects observed when graphene is doped with electrons versus holes.

A better understanding of this electron–hole asymmetry could lead to new ways of generating exotic material phases, including unconventional superconductivity.
