Graphene sodium-ion batteries show promise as effective alternative

By RI Nanotech India

Researchers at Washington State University are working on graphene based sodium-ion batteries that might provide a less expensive, viable alternative to lithium-ion batteries. The researchers used tin oxide nanocrystals supported on a graphene structure to vastly improve the battery. The team explained that technology also could be used in lithium-ion batteries, making it more attractive for manufacturing. In sodium batteries, sodium-ions, rather than lithium-ions, travel back and

Sanitary Products

By RI Nanotech India

Globally, 2.3 billion people live without basic sanitation services and in developing countries, only 27% of people have adequate handwashing facilities at home, according to UNICEF. Not being able to use these facilities makes it harder for women and young girls to manage their periods safely and with dignity. Poor menstrual hygiene can cause physical health risks and has been linked to reproductive and urinary tract infections, according to UNICEF. It also stops women from reaching their full potential when they miss out on opportunities crucial to

What is Graphene?

By RI Nanotech India

Graphene was first observed in electron microscopes in 1962 supported on metal surfaces. It was rediscovered in 2004 by Novoselov and Geim. They were awarded the Nobel Prize in Physics 2010 “for groundbreaking experiments regarding the two-dimensional material graphene”. Since 2010, graphene has attracted a growing interest for many applications. Graphene comprises carbon atoms that are bonded together in hexagonal patterns. Mono-layered and double-layered graphene is so thin that it can

Graphene Oxide

By RI Nanotech India

Graphene is a single layer of pure carbon and is formed when carbon atoms are bonded into hexagonal patterns. Graphene is considered to be two dimensional because its layer is too thin. Before graphene was discovered on 2004 scientists believed that two dimensional compounds could not exist because they would be too unstable. Graphene however though its bonded hexagonal lattice pattern is

Graphene Aerogel

By RI Nanotech India

Graphene aerogel is one of the world’s lightest materials, with an extraordinarily low density. This low density, in combination with the hydrophobic properties of graphene sheets, makes graphene aerogel a promising candidate for oil absorption. The capacity of absorption approaches several hundred times (or two orders of magnitude) higher than that of commercially-available materials for

Reduced Graphene Oxide

By RI Nanotech India

Reduced graphene oxide (rGO) is the form of GO that is processed by chemical, thermal and other methods in order to reduce the oxygen content, while graphite oxide is a material produced by oxidation of graphite which leads to increased interlayer spacing and functionalization of the basal planes of graphite. Graphene oxide is a unique material that is a single monomolecular layer of graphite with various oxygen containing functionalities such as epoxide,
