Things that occur on the surface are frequently given short shrift when compared to what occurs on inside. However, with chemical reactions, what happens on the surface can mean the difference between a working material and one that refuses to carry out its duty.
Graphene is an ultra-thin material that is just a single carbon atom in thickness, and has the potential to be used impressive applications such as friction-free, wear-resistant coatings. But first, large sheets of graphene have to be manufactured under precisely controlled conditions.
For more than 50 years, silicon chipmakers have developed innovative methods to switch electricity off and on, by producing the digital zeroes and ones to encode pictures, words, movies and other forms of data.
Recently, a team of researchers from Graphene Flagship partner Italian Institute of Technology (IIT), Italy and Italian luxury design company, Momodesign participated in a collaborative project where they built a motorcycle helmet that includes graphene technology.
Graphene is a two-dimensional sheet form of carbon with a thickness of just one atom. The exceptional electrical conductivity, strength, and chemical stability have paved the way for extensive research on graphene. Despite long-term research, specific basic characteristics of graphene - such as its reaction to a material sliding on its surface - are yet not completely understood.
A team of researchers at The University of Manchester have formulated a new technique of developing optoelectronic circuits using graphene and other 2D materials that are comparatively smaller than their existing counterparts.
After conducting a decade-long thorough research on graphene and 2D materials, a new semiconductor material, known as Indium Selenide (InSe), was found to exhibit the potential for prospective super-fast electronics.
The unique properties of graphene can be both a blessing and a curse to researchers, particularly to those at the junction of electronic and optical application. The flexible profiles of these atom-thick sheets have highly mobile electrons, which make them efficient conductors, but generally graphene sheets do not interact efficiently with light.
Researchers from Rice University have found that an atom-thick material suggested for use in next-generation optical devices and flexible electronics is more brittle than anticipated.
The addition of hydrogen to graphene could improve its future applicability in the semiconductor industry, when silicon leaves off. Recently, researchers at the Center for Multidimensional Carbon Materials (CMCM) within the Institute for Basic Science (IBS) gained additional insights into this chemical reaction.
