Graphene sodium-ion batteries show promise as effective alternative
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…

Menstrual health 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…

Water in the Sustainable Development Goals In 2015, world leaders agreed to adopt the Sustainable Development Goals (SDGs), in order to eradicate poverty, protect the planet and ensure prosperity for all by 2030. These goals apply to all countries and cover several sectors, such as climate change or gender inequalities. The number 6 is dedicated to…

Graphene and paints Graphene’s myriad of exceptional qualities can open the door to many interesting types of paints and coatings. Graphene’s high resistivity can make for durable coatings that do not crack and are resistant to water and oil, its excellent electrical and thermal conductivity can be used to make various conductive paints, and a…

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…

What is Magneto-rheological fluid ? Magneto-rheological fluid (MRF) is a type of smart material whose rheological properties (e.g. Viscosity) can be rapidly varied by applying a magnetic field. It is a free-flowing liquid state in the absence of a magnetic field while its viscosity increases on application of magnetic field. MRF can be controlled (increased…
Read MoreReduced Graphene Oxide
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…

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…

WHAT IS GRAPHENE? 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…
