• WACKER Acquires a Stake in UK Battery Materials Specialist Nexeon

  Wacker Chemie AG is intensifying its research activities on silicon-based materials for high-performance batteries by taking a holding in Nexeon Ltd. The Munich-based chemical company announced that it is acquiring a 25 percent stake in the UK specialist for new battery materials. WACKER and Nexeon more

• Porous silicon layers for more efficient lithium-ion batteries
  

  The Fraunhofer FEP has developed coating processes for industry for several years. Recently in the project PoSiBat, Fraunhofer FEP scientists were able to develop a non-toxic and efficient manufacturing process for porous silicon layers. The results of the recently completed project will be presente more

• Playfully discover atom manipulation
  

  The team of Toma Susi at the University of Vienna uses a state-of-the-art electron microscope, the UltraSTEM, to manipulate strongly bound materials with atomic precision. Since the instruments used are fully computerized, it is possible to show in a simulation how researchers actually use them. Thi 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

Group 4 Elements

This latest infographic focuses on the Group 4 (Group 14 in IUPAC nomenclature) elements. One extra fact to add for the curious: although tin has the greatest number of stable isotopes, Xenon trumps it comprehensively if unstable isotopes are also included in the count, with well over 30 possible is 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

• Novel magnetite nanorods decorated Si-Schiff base complex for efficient immobilization of U(VI) and Pb(II) from water solutions

  A novel silicon Schiff base complex (Si-SBC) and magnetite nanorods decorated Si-SBC (M/SiO2-Si-SBC) were synthesized and well characterized in detail. The synthesized materials were applied for the removal of U(VI) and Pb(II) from water solutions under various experimental conditions. The monolayer more

• Electro-analytical investigation of potential induced degradation in mc-silicon solar cells: case of sodium ion induced inductive loop

  Potential induced degradation of shunt type (PID-s) in multi-crystalline silicon (mc-Si) solar cells is becoming critical for performance reduction of solar panels in large scale photovoltaic (PV) power plants. In this article PID-s has been investigated by applying high voltage stress on mc-Si sola more

• Large area efficient interface layer free monolithic perovskite/homo-junction-silicon tandem solar cell with over 20% efficiency

  Monolithic perovskite/silicon tandem solar cells show great promise for further efficiency enhancement for current silicon photovoltaic technology. In general, an interface (tunnelling or recombination) layer is usually required for electrical contact between the top and the bottom cells, which incu more

• How the Avogadro constant was measured for the last time
  

  Since the 20th of May 2019, the mass unit kilogram is no longer defined by the international kilogram prototype but by the numerical value of the Planck constant, the most important fundamental constant in quantum physics. For this definition, the Planck constant needed to be measured with the greatest possible accuracy by two independent methods. 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
