Mitsubishi develops MWIR and LWIR graphene-based sensors

Mitsubishi has reportedly developed graphene-based MWIR sensors with extraordinarily high sensitivity. Thanks to an internal graphene FET gain, the responsivity is said to be 10 times higher than that of quantum-type IR sensors with no internal amplification. Mitsubishi uses graphene FET and leverages its high electron mobility.

Other than a graphene-based FET, reports suggest that there is "a light-amplifying part" that produces photoelectrons and photoholes and is placed under the graphene. At a very low temperature of, for example, 80K, the responsivity increases even more, by a factor of 100x.

Cardea raises $7.8 million Series A-1 financing

Cardea, (formerly called Nanomedical Diagnostics), U.S-based manufacturer of a biology-enabled transistor technology made from graphene-based biosensors, announced that it raised $7.8 million Series A-1 financing.

The round was led by Alexandria Venture Investments, with participation from new and existing investors, including Series A round lead investor Serra Ventures. Jonathan Kabakoff, senior principal, science and technology at Alexandria Venture Investments, has taken a seat on Cardea’s board of directors, joining early investor Tim Hoerr, CEO and managing partner at Serra Ventures.

A hands-on review of Wuxi Graphene Film's CVD graphene heating films

China-based Wuxi Graphene Film (owned by Grahope New Materials and The Sixth Element) produces patterned CVD graphene films for heating applications. These films are adopted by several Chinese device makers for different heating products - for example Grahope's graphene eye mask we recently reviewed at Graphene-Info.

The team at Wuxi Graphene Film was kind enough to send a few such films for us to review. These specific films are designed for one of WGF's customers and include a proprietary design which includes a USB connector for easy setup - you just plug these into a USB power source and the films heat up very quickly.

Novel graphene film offers new concept for solar energy

Researchers at Swinburne, the University of Sydney and Australian National University have collaborated to develop a solar absorbing, ultra-thin graphene-based film with unique properties that has great potential for use in solar thermal energy harvesting.

The 90 nanometre material is said to be a 1000 times finer than a human hair and is able to rapidly heat up to 160°C under natural sunlight in an open environment.

Chinese researchers achieve photo-induced ultrafast active ion transport through graphene oxide membranes

Researchers from the Chinese Tsinghua University and CAS demonstrated a coupled photon-electron-ion transport phenomenon through graphene oxide membranes. Using the energy of light, cations are able to move thermodynamically uphill over a broad range of concentrations, at rates orders of magnitude faster than that via simple diffusion.

Based on this mechanism, the team further developed photonic ion switches, photonic ion diodes, and photonic ion transistors as the fundamental elements for active ion sieving and artificial photosynthesis on synthetic nanofluidic circuits.

Graphene Composites exceeds crowdfunding target for graphene bulletproof shields

Graphene Composites, a UK-based company developing graphene-enhanced bulletproof shields, has exceeded its crowdfunding target. GC attempted to raise £300,000 on Crowdcube, but ended up raising £510,680 (around 676,625 USD).

Once Graphene Composites had hit its crowdfunding target, the company sent out a message to its supporters saying: “Thank You - by investing in GC, you have not only invested in a company that should provide you with a healthy return and strong dividends, you are also enabling us to develop and deliver products that will truly improve the quality of life for many around the world. For example, our GC Shield active shooter protection in schools now, and eventually our Lightning Harvester renewable energy sources. Thank You, from all of us on the GC Team”.

ECD Lacrosse and Global Graphene Group (G3) develop graphene-enhanced Lacrosse gear

ECD Lacrosse, manufacturer of high quality lacrosse equipment, has teamed up with Global Graphene Group (G3) to develop ECD's Rebel +Graphene heads, which were released in a limited edition.
