Is Tesla developing a graphene-enhanced Li-Ion battery?

Tesla's CEO is reportedly unhappy with its current Li-Ion battery technology. He announced plans to develop a battery with almost double the current capacity. A Chinese media report claims that these batteries use graphene.



This makes sense as we've seen graphene-based battery prototypes achieving over four times the capacity of commercial batteries, and it seems that the technology is ready for commercialization:…

One-step method to prepare a carbon material from used cigarette filters

Researchers from Seoul National University developed a one-step method to prepare a carbon material (which they call NCF) from used cigarette filters.



They used the NCF to create supercapacitor electrodes - which exhibit a better rate capability and higher specific capacitance compared to conventional activated carbon - and even perform better than graphene or carbon nanotube electrodes!…

Samsung developed graphene quantum dots based flash memory devices

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…

Researchers use regular pencil and paper to create graphene-based sensors

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…

The world's largest graphene production plant is now operational in China

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.



Ningbo Morsh…

The NSF awards $1.5 million towards a new roll-to-roll graphene nanopetals production process research

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…

Adding holes to graphene

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…

Welcome - about us

Welcome! Nanopaprika was cooked up by Hungarian chemistry PhD student in 2007. The main idea was to create something more personal than the other nano networks already on the Internet. Community is open to everyone from post-doctorial researchers and professors to students everywhere.

There is only one important assumption: you have to be interested in nano!

Nanopaprika is always looking for new partners, if you have any idea, contact me at editor@nanopaprika.eu
