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 ...

Artificial leaf as mini-factory for medicine

Using sunlight for sustainable and cheap production of, for example, medicines. The 'mini-factory' in the form of a leaf that chemical engineers from Eindhoven University of Technology presented in 2016 showed that it is ...
