"Spicy world of NanoScience" since 2007
Researchers are developing flash memory devices that store the charge in nanocrystals instead of the usually used polysilicon layers. These kinds of devices are less sensitive to local defects and offer high-density memory potential.
Researchers from Samsung Electronics (and Korea's Kyung Hee University) are now developing similar flash devices based on graphene quantum dots (GQDs). The performance of such a device is promising, with an electron density that is comparable to…

Graphene-developer XG Sciences announced that Samsung Ventures placed a strategic investment. Samsung SDI, the world's largest li-ion battery maker and XG Sciences will co-develop next-gen graphene based batteries:
Students from Northwestern University managed to use pencils and regular paper to create functional sensor devices. They created two types of sensors - strain sensors and chemical vapor sensors.
The students had a discussion about the conductive properties of graphene. They realized that when you draw a line on a piece of paper with a pencil, the pencil's graphite sheds numerous graphene sheets. They started exploring what these graphene sheets can be used for... and, well, you…

China's Ningbo Morsh Technology's graphene production line, with its annual capacity of 300 tons (or tens of millions of graphene films) is now online.
China plans to build a state-level graphene industrialization base in China's Chongqing Municipality. Within 5 years, they hope to reach revenues of 100 billion yuan ($16.35 billion). If the current capacity is indeed 300 tons per year, than China is now the world's leading graphene producer by far.

Researchers at Purdue University are developing a new graphene "nanopetals" mass production process based on a roll-to-roll process. Those nanopetals are graphene-based vertical nanostructures that look like tiny rose petals, and they have applications in sensors, heat-management, supercapacitors and batteries. This research is funded with a $1.5 million grant from the NSF, and aims to increase the production speed of nanopetal-coated surfaces to 10 square meters per hour (a dramatic…Continue

Graphene (a sheet of carbon just one atom thick) can be successfully p-doped with boron, according to new experiments by researchers at Columbia University in the US. The result means that the carbon material can be both electron- and hole-doped, something that is important for advancing real-world graphene-based electronics. B dopants in graphene Chemical doping can be used to add or remove electrons from a material. Two years ago, a team led by Abhay Pasupathy showed that graphene could be…Continue

Researchers from Korea's KAIST institute developed a lithium-air rechargeable battery using a nano fiber graphene composite catalyst. This battery has five times greater storage compared to current lithium-ion batteries, and is the highest performing lithium-air batter ever developed with a good lifespan to boot. Such batteries may enable electric vehicle to travel almost a 1,000 kilometers on a single charge:…

UK's Durham Graphene Science announced plans to go public, and raise up to £10 million (about $16 million) on the UK's AIM stock exchange. The company is also changing its name to Applied Graphene Materials (AGM). They will use the fund to increase production capacity and accelerate commercial opportunities with partners.
If successful, AGM will be the world's first pure-graphene company to go public. This will be one interesting IPO to watch!…

Researchers from the University of Florida and Hunan Univeristy developed DNA-directed silver nanoparticles (Ag NPs) grown on graphene oxide (GO). These so called Ag@dsDNA@GO composites act as antibacterial agents, decreasing X. perforans (a model plant pathogenic bacterium) cell viability in culture and on plants.
In a greenhouse experiment they applied this material on tomato transplants and they reported significant reduction of disease caused by bacterial spot compared to the…
