Source: NIMSTsukuba, Japan, Jan 28, 2014 - (ACN Newswire) - Japan's National Institute for Materials Science (NIMS) and the Swiss Federal Laboratories for Materials Science and Technology (Empa) have signed a 5-year collaborative agreement to co-publish the open access journal Science and Technology of Advanced Materials (STAM). Their goal is to make STAM one of the world's leading publications in materials science. Founded in 2000, Science and Technology of Advanced Materials provides an...

Recipe For High-efficiency Solar Cells
2013-11-06 09:44:43

Swiss Federal Laboratories for Materials Science and Technology (EMPA) For many years scientists and engineers have been trying to provide low-cost solar energy by developing a cheap solar cell that is both highly efficient and at the same time simple to build, enabling it to be mass produced. Now, the team led by Empa researcher Ayodhya N. Tiwari has made a major leap forward: the researchers are presenting a new manufacturing technique for CIGS solar cells, in which tiny quantities of...

Flame retardants are often extremely harmful to health. Despite this, they are found in many types of synthetic materials which would otherwise ignite quickly. Empa researchers have now succeeded in producing non-harmful flame retardants. Synthetic materials made from organic polymers usually burn very well due to their high carbon content; when turned into foams, they ignite even more easily – and, depending on their chemical compositions, they produce toxic gases such...

First tops, then flops. That is one way of summing up the history of biofuels so far. A new study led by Empa gives an up-to-date picture of the ecobalance of various biofuels and their production processes. Only a few are overall more environmentally friendly than petrol. In recent years, the demand for supposedly environmentally friendly biofuels has increased significantly worldwide; on the one hand, this has resulted in the increased cultivation of so-called energy plants and, on the...

For 75 years Empa has been conducting research on all aspects relating to wood. Beginning with an investigation into the properties of various types of indigenous woods, today this has grown into a research area with many branches — from fundamental research on the structure of wood to chemically or biologically modified woods, novel wood fiber products and surface technologies. Empa scientists examine each of the material´s properties in minute detail and use these results to...

True luxury has only one color — gold. A nanometer-thin layer of pure gold now lends ties and pocket handkerchiefs that authentic gold sheen, thanks to a new Empa-developed process. The yarn, which is coated using a high-tech plasma process, is soft and easy to weave. It is also washing machine compatible. A limited number of gold ties will be placed on the market before Christmas, making a truly exclusive present. Further fashion accessories will follow in 2012. Gold radiates with a...

Nanotech is opening up new markets and offering novel solutions to numerous challenges in a very varied range of areas. This was the tenor of the 1st Swiss NanoConvention which took place on May 18 and 19 in Baden. The event was organized by Empa, the Paul Scherrer Institute (PSI) and the ETH Zurich, and offered the 300 or so decision-makers who participated a practical platform on which to discuss and exchange ideas not just about developments in the nanosector which are beneficial to...

Researchers at Empa, in cooperation with textile designer Annette Douglas and silk weavers Weisbrod-Zrrer AG, have developed lightweight, translucent curtain materials, which are excellent at absorbing sound. This is a combination that has been lacking until now in modern interior design. And the new "noise-quenching" curtains have just gone onto the market. Noise is annoying. It interrupts communication, reduces productivity and tires people out "“ in extreme cases it can even make...

Breezy research for the 'Smart Cities' of the future A typical city: row upon row of houses built almost on top of each other, with asphalted roads between them and with very few green areas to be found. Urban areas built on this pattern warm up more strongly than their rural surroundings, creating islands of warmth. The waste heat emitted by vehicles and machinery (such as air conditioning equipment) causes yet more heating, and even during the night the city hardly cools down to any...

Computational power against noise Working together with an international project team, Empa's acoustic specialists have developed a computer model which allows them to calculate noise levels along the entire Swiss rail network. The program describes how much sound is radiated and how it is attenuated. The results will one day show in high precision where residents are particularly exposed to noise and what abatement measures will be most effective in protecting them. Goods trains move at...
