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…

Graphene enables long lasting lithium-air batteries that can enable electric cars with almost 1,000 kilometers range

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:…

DNA-guided Silver and Graphene-Oxide prove to be a great anti-bacterial agent in plants

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…

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
