Scientists develop tungsten-based hydrogen detectors

A team of physicists from Immanuel Kant Baltic Federal University together with their colleagues from National Research Nuclear University MEPhI (NRNU MEPhI) has developed a tungsten oxide-based detector of hydrogen in gas ...

An unlikely marriage among oxides

The term alloy usually refers to a mixture of several metals. However, other materials can also be alloyed. In the semiconductor industry, for instance, oxide and nitride alloys have long been used successfully to tune the ...

Rewritable material could help reduce paper waste

Even in today's digital age, the world still relies on paper and ink, most of which ends up in landfills or recycling centers. To reduce this waste, scientists have now developed a low-cost, environmentally friendly way to ...

Nano plates as catalysts for solar fuels

Solar fuels, clean fuels from sunlight, water and CO2, form an attractive way for storing solar energy in hydrogen or hydrocarbons, for example. The efficiency of this technology still needs a 'boost'. Researcher Kasper Wenderich ...

Super-slick material makes steel better, stronger, cleaner

Steel is ubiquitous in our daily lives. We cook in stainless steel skillets, ride steel subway cars over steel rails to our offices in steel-framed building. Steel screws hold together broken bones, steel braces straighten ...

Anti-aging treatment for smart windows

Electrochromic windows, so-called 'smart windows', share a well-known problem with rechargeable batteries – their limited lifespan. Researchers at Uppsala University have now worked out an entirely new way to rejuvenate ...

Collecting light with artificial moth eyes

All over the world researchers are investigating solar cells which imitate plant photosynthesis, using sunlight and water to create synthetic fuels such as hydrogen. Empa researchers have developed such a photoelectrochemical ...
