In the last few years, the world has witnessed huge political upheaval such as Donald Trump’s election, Britain’s exit from the EU, the recent French election and this month’s snap election results in the UK. Meanwhile, four decades since its inception, nanotechnology continues to effect an increasingly diverse range of fields and promises to revolutionize […]
Bulk gold is chemically inert, but when the size of gold particles is reduced to nanometre or sub-nanometre dimensions they begin to have very different physical and chemical properties. A team of researchers at the National University of Singapore has now found that gold nanoparticles smaller than around 2 nm are antimicrobial and can kill […]
Carbon nanotubes zapped with microwaves can be used to locally heat up 3D-printed thermoplastic parts. This new result, from researchers at Texas A&M University, addresses one of the biggest challenges in 3D printing today and allows for strong welds in the build direction….. http://nanotechweb.org/cws/article/tech/69097
Scientists in the US have devised a microfabrication method that uses capillary channels in a photoresist to position nanorods of the tobacco mosaic virus (TMV). The team used the quick and simple new approach to create a supercapacitor with nanostructured electrodes, and the method can be applied to construct many other microdevices requiring high surface […]
An entirely artificial nano-biocatalyst for converting sunlight into hydrogen that works at ambient temperature in water at neutral pH has been developed by researchers at the Argonne National Laboratory in the US. The catalyst, which consists of a synthetic transmembrane proton pump and titanium-dioxide semiconductor nanoparticles, produces around 240 μmol and 17.74 mmmol of hydrogen […]
ANSES has submitted a proposal to the European Chemicals Agency (ECHA) for titanium dioxide to be classified as a Category 1B carcinogen by inhalation. Since 31 May 2016, this proposal has been the subject of a public consultation on the ECHA website to enable interested stakeholders to present their points of view, scientific arguments or […]
The purpose of the international research project NANOaers (= Fate of aerosolised nanoparticles: The influence of surface active substances on lung deposition and respiratory effects) is to establish where airborne, respirable particles remain after they have been inhaled…… http://www.nanowerk.com/nanotechnology-news/newsid=47038.php
The areas of flexible electrodes and strain sensors have seen a lot of growth in recent years, especially as materials with a flexible nature have become more commercialised. One such material used in these applications is reduced graphene oxide (rGO), and a team of researchers from India have now determined the crack dynamics involved when […]
The ability to successfully covalently-functionalise graphene and determine the completed process through Raman spectroscopy is currently used by many researchers today. However, one area which has remained elusive in this process is the determination (and resolution) of the individual lattice modes associated with the covalent bonding mechanism.…… http://www.azonano.com/article.aspx?ArticleID=4495
Graphene is a two-dimensional form of carbon arranged in one-atom thick layers. Carbon atoms in graphene are tightly packed in a regular hexagonal pattern. Mathematically, graphene can be treated as a considerably large aromatic molecule, and due to this electronic and distinctive physical structure, can create new electronic effects.….. http://www.azonano.com/article.aspx?ArticleID=4475
‘Coherent approach’ towards precautionary principle endorsed Germany has adopted its third nanotechnology action plan, which outlines a strategy for the safe and environmentally friendly production of nanomaterials from 2016-2020. The ministry of education and research (BMBF), which submitted the plan, said projects involving nanomaterials will focus on regulatory and safety matters…… https://chemicalwatch.com/50559/germany-launches-2020-nanomaterials-action-plan
Elsevier, a world-leading provider of scientific, technical and medical information products and services, announces the launch of NanoImpact, a new multidisciplinary journal that is devoted to publishing cutting edge research addressing the behavior and impact of nanomaterials on human health and environmental systems. NanoImpact welcomes article submissions in the following four main areas of research: […]
Globally existential threats due to ‘overpopulation momentum’ together with the top-heavy age structure leave by now no alternative to radical technological adaptation for anything that wants to survive ‘long term’. It is strictly too late to ‘go green’ except via a novel take on what constitutes ‘green’, including synthetic biology. Hyped for a long time, […]
Warnings about possible health risks from tiny particles used in some sunscreens have rocked Australians’ faith in them, a new federal government survey shows, and experts fear lives will be lost as a result….. http://www.theage.com.au/national/sunscreen-fear-a-risk-to-health-20130331-2h1hc.html
Nanomaterials are lurking in our foods, but which ones? As the food industry is leaving consumers in the dark, we are left guessing what’s in our food and how it may be slowly killing us. Louise Sales, specialist in the field of nanotechnology dishes out the truth behind the probable dangers and why we should […]
In the quantum world, our intuition for moving objects is strongly challenged and may sometimes even completely fail. Experimental physicists of the University of Innsbruck in collaboration with theorists from Munich, Paris and Cambridge have found a quantum particle which shows an intriguing oscillatory back-and-forth motion in a one-dimensional atomic gas…….. https://nano-magazine.com/news/2017/6/2/breaking-newtons-law
EPFL scientists have built a low-cost and ultra-stable perovskite solar cell that has been running at 11.2% efficiency for over a year, without loss in performance……. https://nano-magazine.com/news/2017/6/1/ultra-stable-perovskite-solar-cell-remains-stable-for-over-a-year
Fluorescent quantum dots are valuable tools used to tag and image biological processes in live animals. However, precise fluorescent imaging at the cellular and molecular levels has not been possible because of non-specific fluorescence and light scattering by surrounding tissues. Now researchers have created short wave infrared (SWIR) quantum dots that resolve many of these […]
Dr Hossein Eslambolchi, technical adviser at Facebook, quoted his top 10 Nano-technology trends earlier this year[1]. Whilst they are “trending”, they can hardly be described as trendy. The difference being, one gets scientists and engineers excited, the other gets the world excited, not about the science of nanotechnology, but about the applications……… https://nano-magazine.com/news/2017/6/2/top-5-trendy-nanotechnology-applications
For many, nanotechnology is viewed as merely a way to make stronger and lighter tennis rackets, baseball bats, hockey sticks, racing bikes, and other athletic equipment. But nanotechnology promises to do so much more. A more realistic view is that it will leave virtually no aspect of life untouched and is expected to be in […]
