Turning streetwear into solar power plants

Researchers at Empa and ETH Zurich succeeded in developing a material that works like a luminescent solar concentrator and can even be applied to textiles. This opens up numerous possibilities for producing energy directly ...

Shining light on the separation of rare earth metals

Inside smartphones and computer displays are metals known as the rare earths. Mining and purifying these metals involves waste- and energy-intense processes. Better processes are needed. Previous work has shown that specific ...

Physicists suggest new way to measure speed in liquid micro-flows

Scientists from ITMO University developed a novel optical method of measuring reagent delivery rates for "labs on a chip." The method is based on a dynamic interaction between a nanoantenna and luminescent molecules as the ...

Molecular switch detects metals in the environment

An international team led by researchers from the University of Geneva (UNIGE), Switzerland, has designed a family of molecules capable of binding to metal ions present in the surrounding environment and providing an easily ...

Positron luminescence outshines that of electrons

In old cathode ray TVs, a picture is generated when an electron beam excites a phosphor screen, causing the phosphor to radiate light. Now in a new study, researchers have found that a beam of positrons (positively charged ...
