Nanoflowers harness sunlight

A one-pot production method is used to create submicron flower-like structures that display high photocatalytic activity, specifically for water splitting to produce hydrogen. This work is a collaboration between Singaporean and Chinese institutions, and represents the forefront of visible light-driven hydrogen evolution research that is both effective and environmental. ……… http://nanotechweb.org/cws/article/tech/70326

Metal-oxide coating makes graphene more versatile – news from the Enlighten Conference 2017

Last month nanotechweb.org attended the Thin Films and Coating Technologies for Science and Industry event at the Ricoh Arena Coventry in the UK. Among the research presented, two projects were focused on coating single-layer graphene with metal-oxide nanolayers. Adrianus Indrat Aria of Cranfield University, UK, together with collaborators from University of Cambridge and the Centre […]

Unexplained huge protein conductances hint at evolution

When electrochemistry, transient charging and heating effects all failed to explain the fluctuating high conductance detected in a human integrin protein, Stuart Lindsay at Arizona State University and his colleagues considered the possibility that the protein’s electronic properties teetered at a critical point between conducting and insulating states…… http://nanotechweb.org/cws/article/tech/70386

This elastic yarn could be the future of power generation

An international team of scientists said in a study they had developed a stretchy yarn made of carbon nanotubes – tiny strands of carbon atoms up to 10,000 times smaller than a hair – that produces electricity from a host of natural sources…….. https://www.weforum.org/agenda/2017/09/this-elastic-yarn-could-be-the-future-of-power-generation?utm_content=buffer825e3&utm_medium=social&utm_source=facebook.com&utm_campaign=buffer

Think laterally to sidestep production problems

Super thin photovoltaic devices underpin solar technology and gains in the efficiency of their production are therefore keenly sought. KAUST researchers have combined and rearranged different semiconductors to create so-called lateral p-n heterojunctions–a simpler process they hope will transform the fabrication of solar cells, self-powered nanoelectronics as well as ultrathin, transparent, flexible devices……. https://www.nanotechnologyworld.org/single-post/2017/10/17/Think-laterally-to-sidestep-production-problems?utm_campaign=buffer&utm_content=buffer4c334&utm_medium=social&utm_source=facebook.com

Playdough-inspired technique makes patchy particles

Researchers in the US and South Korea have developed a new technique dubbed “colloidal fusion” to construct patchy nanoparticles that can spontaneously self-assemble into a myriad of more complex architectures. The method might be used to fabricate the building blocks for a wide variety of electronics and optoelectronics devices….. http://nanotechweb.org/cws/article/tech/70007

Nanogels help repair the heart

A nanogel containing stem cells could be used to help repair damage to the heart following a heart attack. This is the new result from researchers in China, Australia and the US, who say that their technique stimulates cell regeneration in cardiac tissue without triggering an inflammatory response….. http://nanotechweb.org/cws/article/tech/70021

Graphene-munching spiders produce stronger silk

In a bizarre-sounding experiment at Cambridge as part of the EU Graphene Flagship’s Composites Work Package, the researchers sprayed solutions containing graphene and CNTs into a tank containing spiders. Afterwards, they collected silk the spiders had produced, compared it with silk from before they had their carboniferous lunch, and obtained surprising results….. https://nano-magazine.com/news/2017/9/18/graphene-munching-spiders-produce-stronger-silk/?email=pr@nanotec.or.th
