Technology Update

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

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 […]

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 […]

Nanotechnology has been hailed as the next big thing for decades, but it is only now that it is truly becoming a reality in the medical device space. The term nanotechnology itself dates back to the 1980s, when it was coined by U.S. engineer Eric Drexler. In the past few decades, nanotech has found a […]

At one time you could wander through the labs of pharmaceutical companies and hardly ever see light being used to mediate chemical reactions. Now “photoredox catalysis” has become an essential way to synthesize novel organic compounds……. https://nano-magazine.com/news/2017/5/29/light-emitting-quantum-dots-could-ease-synthesis-of-novel-compounds

The shells of marine organisms take a beating from impacts due to storms and tides, rocky shores, and sharp-toothed predators. But as recent research has demonstrated, one type of shell stands out above all the others in its toughness: the conch….. https://nano-magazine.com/news/2017/5/27/conch-shells-spill-the-secret-to-their-toughness

Heterostructures based on 2D layered semiconductors such as gallium selenide (GaSe) and conventional 3D semiconductors such as gallium nitride (GaN) could be used to make novel, high-performance electronics and optoelectronics devices. However, such devices will require high-quality materials at the wafer scale with excellent crystalline order and sharp interfaces. A team of researchers at The […]

Researchers at the University of Virginia and Johns Hopkins University School of Medicine in Baltimore have developed a new, non-invasive and non-toxic genetic therapeutic technique to restore dopaminergic neuron function in rats suffering from Parkinson’s disease. The technique, which makes use of magnetic-resonance-image-guided ultrasound and brain-penetrating nanoparticles, reverses neurodegeneration thanks to expression of the neurotrophic […]

“Thermally activated delayed fluorescence” (TADF) materials are promising for a number of applications ranging from imaging and security, to solar cells and light-emitting diodes and the pixels used in flat panel displays. However, most of the TADF materials made so far are based on metal-organic complexes and organic molecules that have lifetimes of only several […]

Researchers at Columbia University in New York have observed a Bose-Einstein condensate of excitons in the quantum Hall regime in a double bilayer graphene heterostructure. Such a system is thought to host an excitonic analogue of the superconducting state at high temperature and zero magnetic field and so could be used to study strongly interacting […]

The sun is a good source of Vitamin D which is very important to the body. On the other hand, overexposure to the heat of the sun can lead to skin cancer. Thus, doctors advise people to put on some sunscreen for protection. Recently, nanotechnologists have developed a sunscreen that produces melanin…… https://nano-magazine.com/news/2017/5/24/scientists-created-a-sunscreen-that-produces-melanin

Nanolabs, a company specialised in nanotechnology, has been able to increase the production of melons by up to 40% on a farm in Almeria, thanks to the installation of ASAR systems in the irrigation system of the farm…….. https://nano-magazine.com/news/2017/5/18/up-to-40-more-melons-thanks-to-nanotechnology  

A plant grower from the UK has helped grow what is believed to be the world’s hottest chilli pepper, after “introducing nanofeed into the plant”….. https://nano-magazine.com/news/2017/5/22/worlds-hottest-chilli-pepper-grown-using-nanofeed
