Researchers from the University of Surrey have revealed a new method that enables common laboratory scanning electron microscopes to see graphene growing over a microchip surface in real time.
This discovery, published in
ACS Applied Nano Materials, could create a path to control the growth of graphene in production factories and lead to the reliable production of graphene layers.
Dispensing with the use of expensive bespoke systems, the new technique not only produces graphene sheets reliably but also allows to use fast-acting catalysts that reduce growth times from several hours to only a few minutes.
With the use of video imagining, the team from Surrey s Advanced Technology Institute (ATI) have shown graphene growing over an iron catalyst, using a silicon nitride membrane produced within a silicon chip. The membrane is only a few tens of nanometres thin, and heating and cooling can be rapidly controlled by means of modulating an electrical signal that is sent

VinTech Nano Materials LLC (Springdale, Ark.) has announced the launch of Armor GFC Coating, an advanced nanoengineered tribological coating for alleviating chemo-mechanical damage from aggressive wear, galling, and adhesive friction in corrosive environments.
The leading-edge multicomponent GFC coating offers flexible curing options in ambient conditions and as well as accelerated thermal curing. Ambient curing allows for onsite and offsite coating of components of almost any dimensional configuration without the need for disassembly or downtime.
Armored with VinTech’s innovative organofunctionalized nanocarbon technology, the coating offers improved resistance against galling (75-250 KSI), adhesive wear and friction (up to 0.01 coefficient of friction).
Shining up Carbon Nanodots: A New Synthesis Pathway for Enhanced Fluorescence
Written by AZoNanoApr 12 2021
Scientists have developed a novel strategy to produce near-oxygenless carbon nanodots, helping shed light on the role of oxygen in their optical properties.
Carbon nanodots (CNDs) are a promising type of fluorescent material with potential applications in many fields, including optoelectronics, photocatalysis, and medicine. However, the role of oxygen in CND fluorescence is unclear because conventional synthesis methods cannot produce CNDs without oxygen for comparative analyses. In a recent study, scientists from Sookmyung Women’s University, Korea, have developed a new synthesis pathway to easily obtain near-oxygenless CNDs, paving the way to a deeper understanding of their attractive properties.
