A new study shows that a 70-year-old malaria drug can block immune cells in the liver so nanoparticles can arrive at their intended tumor site, overcoming a significant hurdle of targeted drug delivery, according to a team of researchers led by Houston Methodist….. https://nano-magazine.com/news/2017/11/7/70-year-old-malaria-drug-found-to-improve-treatment-of-tumors/?email=ramjitti@nanotec.or.th
A leading scientist battling to halt the development of Multiple Sclerosis has revealed that clinical human trials will start by 2020, after her company was honoured with a major nano medicine award. Dr Su Metcalfe’s regenerative nanomedicine company, LIFNano™, was named Most Promising Nanomedicine Project at the International Nano Medicine Awards in Berlin on Tuesday, November […]
By incorporating divalent cations into alginate solutions, PhD student Thomas Valentin and colleagues at Brown University in the US have produced a noncovalently crosslinked hydrogel that is responsive to multiple stimuli. …… http://nanotechweb.org/cws/article/tech/70311
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
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 […]
Instead of cooling down a whole building in hot weather, it would be more cost-effective and environmentally friendly to simply wear clothing that could efficiently carry away excess body heat. ……… http://nanotechweb.org/cws/article/tech/70331
Parrotfish feed by biting stony corals so they need highly stiff, hard, fracture-tough and abrasion-resistant teeth. New chemical analyses, nano-indentation tests and polarization-dependent imaging contrast mapping experiments by a team of researchers in the US and Singapore has now revealed that they indeed have all these properties. ……… http://nanotechweb.org/cws/article/tech/70376
Flexible electronics, microfluidics and other cutting-edge engineering applications utilize two-dimensional (2D) metal oxides. These oxide layers are thin yet powerful sheets that combine the useful bulk electronic properties of the oxide with the high surface area activity of nanomaterials. …. http://nanotechweb.org/cws/article/tech/70377
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
Researchers at McMaster University in Canada are reporting on a new type of multi-spectral infrared camera that addresses many of the shortcomings of current IR cameras. …. http://nanotechweb.org/cws/article/tech/70388
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
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

UCF researcher Yang Yang has come up with a new hybrid nanomaterial that harnesses solar energy and uses it to generate hydrogen from seawater more cheaply and efficiently than current materials. The breakthrough could someday lead to a new source of the clean-burning fuel, ease demand for fossil fuels and boost the economy of Florida, […]
Strained interfacial phase-change materials (iPCMs) offer a fast and energy-efficient way to write and store computer data. Devices based on this technique could improve on current media by encoding information in three dimensions. Now, researchers in Singapore and China have shown that the speed at which interfacial phase-change proceeds is due to a self-reinforcing avalanche […]
Structural colours are unlike colours produced by chemical dyes and pigments in that they originate from resonant interactions between visible light and engineered nanostructures. These colours do not fade over time – the way ink does. A team of researchers from the US and Belgium has now developed a simple, one-pot reverse emulsion process to […]
