New graphene-based sensor could improve food safety and detect gases and chemicals

researchers from Jiliang University and Zhejiang University of Technology in China, along with researchers at the Technical University of Denmark, have devised a new design for a graphene-based sensor that can simultaneously detect multiple substances - including dangerous bacteria and other pathogens. In addition to food safety, the new design could improve detection of gases and chemicals for a wide range of applications.

"Our design is based on graphene sheets, which are two-dimensional crystals of carbon just one atom thick," said research team member Bing-Gang Xiao, from China Jiliang University. "The sensor is not only highly sensitive but can also be easily adjusted to detect different substances."

Team at Australia's RMIT finds silicon contamination of graphene as a hindrance to commercial adoption

Researchers at Royal Melbourne Institute of Technology (RMIT) have found that graphene could better fulfill its potential when purified to remove silicon, doubling its electrical performance.

Despite researchers demonstrating countless possible applications of graphene, many people feel that graphene is thus far showing rather sluggish industrial adoption. Now, researchers based at RMIT have proposed a possible reason for this and suggested how graphene's full potential could be unlocked.

India's Log 9 Materials develops graphene-based metal-air battery

India-based Log 9 Materials is working graphene-based metal-air batteries, that in theory may even lead to electric vehicles that run on water.

The metal air batteries use a metal as anode, air (oxygen) as cathode and water as an electrolyte. A graphene rod is used in the air cathode of the batteries. Since Oxygen has to be used as the cathode, the cathode material has to be porous to let the air pass, a property in which graphene excels. According to Akshay Singhal, co-founder of Log 9 Materials, the graphene used in the electrode is able to increase the battery efficiency by five times at one-third the cost.

Thales and M-SOLV develop large-scale spray coating tool for graphene supercapacitors

Graphene Flagship partners Thales and M-SOLV have developed a large-scale spray coating tool, reportedly capable of meeting the high volume manufacturing requirements for high power graphene supercapacitors to be used in aerospace applications.

Thales has been working on incorporating graphene into supercapacitors since the start of the Graphene Flagship and has been able to significantly increase the storage potential of supercapacitor devices. "Using graphene, we have been able to increase the power of supercapacitors by five times. We deposited our supercapacitors using spray coating, enabling us to use a variety of substrates, thus allowing us to develop flexible, high power supercapacitors," said Dr. Paolo Bondavalli, Thales Research and Technology.

SiNode changes name to NanoGraf following agreement with JNC to jointly commercialize graphene-silicon Li-ion batteries

NanopGraf logo imageSiNode Systems, a U.S-based developer of silicon-graphene materials for lithium-ion batteries, and JNC Corporation, a Tokyo-based specialty chemical manufacturer, have formed NanoGraf Corporation—a joint venture focused on commercializing advanced materials for the Lithium-ion battery industry—with a $4.5-million investment. SiNode will be renamed NanoGraf.

NanoGraf’s technology aims to enhance the performance of battery materials using a proprietary graphene-wrapped silicon anode, originally invented at Northwestern University. The unique combination of silicon-based alloys and a flexible 3D graphene network reportedly helps stabilize the active material during charge and discharge. NanoGraf materials states that it enhances battery energy and power density by up to 50% and offers best-in-class cycle life.
