Organic photovoltaic devices (OPVs) have major potential as a principal source of clean electricity for the future. However, the large-scale introduction of OPVs onto the market is currently limited by their stability. The StableNextSol Action aims to create a highly interdisciplinary network of academic and industry researchers to study the degradation mechanisms occurring in state-of-the-art OPVs.
Until now, if you want to print a greeting card for a loved one, you can use colorful graphics, fancy typefaces or special paper to enhance it. But what if you could integrate paper-thin displays into the cards, which could be printed at home and which would be able to depict self-created symbols or even react to touch?
To enable society to build and sustain a green economy, the associated concept of 'green nanotechnology' aims to exploit nano-innovations in materials science and engineering to generate products and processes that are energy efficient as well as economically and environmentally sustainable.
The aim of ACIN 2015 is to offer an update of recent innovations in both fundamental and applied aspects highlighting new advances and progress in the field of nanomaterials (inorganics, hybrids, molecular and bio-inspired).
Optical dyes can be used to control color and light in applications ranging from laser welding to production of sunglasses and plasma TVs. The dyes used for this purpose are often expensive; others are cheap but apt to decompose when exposed to heat. A better set of options - optical dyes that are both economical and stable - is about to hit the market.
Researchers have developed a novel method for improving silicon-based sensors used to detect biochemicals and other molecules in liquids. The simplified approach produces micro-scale optical detection devices that cost less to make than other designs, and provide a six-fold increase in sensitivity to target molecules.
Green tea has long been known for its anti-oxidant, anti-cancer, anti-aging and anti-microbial properties. A group of researchers has taken the health benefits of green tea to the next level by using one of its ingredients to develop a drug delivery system, which kills cancer cells more efficiently.
Nanoparticles have the potential to revolutionize the medical industry, but they must possess a few critical properties. First, they need to target a specific region, so that they do not scatter throughout the body. They also require some sort of sensing method, so that doctors and researchers can track the particles. Finally, they need to perform their function at the right moment, ideally in response to a stimulus. Scientists are trying to develop new particles with unprecedented properties that still meet these requirements.
Nanoparticles can emit light into ultra-thin glass fibres. Physicists have now managed to select the direction of the light using an unusual kind of coupling between spin and the direction of propagation.
