Long-hypothesized 'next generation wonder material' created for first time

For over a decade, scientists have attempted to synthesize a new form of carbon called graphyne with limited success. That endeavor is now at an end, though, thanks to new research from the University of Colorado Boulder.

Synthesis of two-dimensional holey graphyne

Diamond and graphite are two naturally occurring carbon allotropes that we have known about for thousands of years. They are elemental carbons that are arranged in a manner so that they consist of sp3 and sp2 hybridized carbon ...

Beyond van der Waals: The next generation of covalent 2D-2D heterostructures

A team of scientists have "velcroed" 2D structures of MoS2 and graphene using a covalent connection for the first time. The 2D-2D structures were used to build robust field effect transistors with controlled electronic communication, ...

Directing group-free alkene dicarbofunctionalization through catalyst control

NUS chemists have developed a new "catalyst control" blueprint to overcome a longstanding challenge in the site-selective dicarbofunctionalization of unactivated alkenes, by enabling the reaction to proceed in the absence ...

Âé¶¹ÒùÔºicists describe a new type of amorphous solid bodies

Many substances with different chemical and physical properties, from diamonds to graphite, are made up of carbon atoms. Amorphous forms of solid carbon do not have a fixed crystal structure and consist of structural units—nanosized ...
