Nanjing team develops graphene oxide-based solar desalination system

Dec 05, 2016

Researchers from the Chinese Nanjing University have reportedly developed a graphene oxide-based solar desalination system that does not require a solar concentrator or thermal insulation. Featuring a confined 2D water channel, the system is able to achieve high levels of solar absorption and effective desalination.

The research team stated that it used a graphene oxide film as the basis for a device. The graphene oxide film is said to be foldable and produced using a scalable process. With this at the core of the system, the researchers believe that the development represents "a concrete step for solar desalination to emerge as a complementary portable and personalized clean water solution".

Nanomedical Diagnostics starts shipping its graphene-based sensors, explains its technology and business to Graphene-Info

Researchers design a novel method of graphene production using laser-induced phase separation

Dec 04, 2016

Researchers at the Institute for Basic Science (IBS) and KAIST have designed a graphene synthesis mechanism using laser-induced solid-state phase separation of single-crystal silicon carbide (SiC). According to the scientists, the laser material interaction technology can be a powerful tool for the next generation of 2D materials.

Graphene production technique by laser image

Using molecular dynamic simulations and high resolution microscope images, the researchers discovered that a single-pulse irradiation of xenon chloride excimer laser of 30 nanoseconds melts SiC, causing the separation of a liquid SiC layer, a disordered carbon layer with graphitic domains (approximately 2.5 nm thick) on the top surface and a polycrystalline silicon layer (roughly 5 nm) below the carbon layer. The sublimation of the separated silicon is caused when additional pulses are given, while the disordered carbon layer is changed into a multilayer graphene.

Graphene solves RRAM's failure problems

Dec 01, 2016

Resistive RAM (RRAM) is a promising new next-generation memory technology that is being commercialized by several companies. Researchers at the Chinese Academy of Sciences have been study a device failure caused by two processes in cation-based RRAM, and have discovered that graphene may hold the key.

If a single-layer graphene is added to the device, and used as an ion barrier between two metallic layers in the device, the RRAM cell is more reliable while still maintaining high performance.

Huawei introduces new high-temperature Li-Ion batteries that use graphene to reduce operation temperature and increase the lifetime

Nov 30, 2016

Huawei unveiled a new Li-Ion battery that can remain functional at higher temperature (60° degrees as opposed to the existing 50° limit) and offers a longer operation time - double than what can be achieved with previous batteries.

Huawei graphene-assistant battery design

To achieve this breakthrough, Huawei incorporated several new technologies - including an anti-decomposition additives in the electrolyte, chemically stabilized single crystal cathodes - and graphene to facilitate heat dissipation. Huawei says that the graphene reduces the battery's operating temperature by 5 degrees.

Avanzare develops graphene-based additives to improve industrial-scale resins

Nov 30, 2016

Avanzare logoThe Spain-based Avanzare, nanomaterials and nanotechnology-based solutions provider and Graphene Flagship partner, has introduced to the market a graphene additive for industrial resins used for corrosion-resistant tanks and pipes for storage and transport of potentially explosive chemicals. Their product will be showcased at the Composites Europe exhibition, running from the 29 November to 1 December in Düsseldorf, Germany.

The company's graphene-based product can be used to help avoid explosions due to electrostatic charges. Avanzare aims to produce vessels and equipment using resins instead of the usual metals; These resins are also cheaper, lighter and have very good corrosion resistance. The graphene-resin, claimed to already be in use in high-volume industry applications, was developed by Avanzare through a collaboration with Ashland, an international chemical manufacturing company. According to company reports, the graphene-resin is already in use in chemical plants across Europe, and Ashland has installed graphene-resin systems in their facilities in Spain.

The Graphene Flagship designs a graphene-based NFC antenna

Nov 30, 2016

The Graphene Flagship's Italian partner CNR-ISOF has found that it is possible to use graphene to produce fully flexible NFC antennas. By combining material characterization, computer modelling and engineering of the device, the Graphene Flagship researchers designed an antenna that could exchange information with near-field communication devices such as a mobile phone, matching the performance of conventional metallic antennas.

The graphene-based NFC antennas are chemically inert, highly resistant to thousands of bending cycles and can be deposited on different standard polymeric substrates or silk tissues. The fully flexible graphene NFC device demonstrators were tested with a smartphone through the NFC reader App by the Graphene Flagship partner STMicroelectronics, showing good functionality whether flat or fixed on curved objects.
