  • Researchers discover ways to expand temperature stability range of solar cells

    Despite the potential for powering the world with energy from the sun - the most abundant source of renewable energy - only about 1 percent of the world's energy production currently comes through solar cell technology. That's because solar cells are expensive to produce and are susceptible to effic more

  • Obtaining of silicon nanowires becomes eco-friendly

    Scientists from the Faculty of Physics, the Lomonosov Moscow State University have worked out a new and more eco-friendly method of silicon nanowires obtaining, which allows to replace hydrofluoric acid (HF) by ammonium fluoride (NH4F). Silicon nanowires are streamlined, almost parallel to each othe more

  • Recharging on stable, amorphous silicon

    Next-generation anodes for lithium ion batteries will probably no longer be made of graphite. Silicon, which is a related material, can provide a much higher capacity than graphite, but its crystallinity poses problems. Chinese scientists have introduced a porous silicon form that is amorphous, not more

The Chemistry of Silly Putty

Silly putty (or science putty, as it’s sometimes referred to) is an odd material. Stretch it slowly and it happily deforms, and can be molded very easily. However, pull it apart with enough force and it’ll snap clean in two. It flows imperceptibly slowly, as if it were a thick liquid, but when rolle more

The Chemical Elements of a Smartphone

There are an isolated few graphics online that look at elements involved in the manufacture of a smartphone – for example, this ‘Periodic Table of iPhones’ – but there’s actually remarkably little easily accessible information out there that details the specific compounds used for specific purposes more

  • The Best Measurement

    It is now more than 30 years since attempts started to find a way of defining the kilogram based on an atomic constant or a fundamental physical constant. Since then, two methods have advanced sufficiently far to make it likely that there will be a new definition within the coming years, namely the Watt balance ­experiment for determination of Planck‘s constant h and the Avogadro experiment for determining the ­Avogadro Constant NA. more
