• Researchers first to link silicon atoms on surfaces

  A team consisting of various working groups from the fields of chemistry and physics are now the first to have linked silicon atoms on surfaces. From silicon polymers, the researchers hope for innovative material properties and new, promising candidates for potential applications. Materials such as more

• Lights on for silicon photonics
  

  When it comes to microelectronics, there is one chemical element like no other: silicon, the workhorse of the transistor technology that drives our information society. The countless electronic devices we use in everyday life are a testament to how today very high volumes of silicon-based components more

• From trash to treasure: Silicon waste finds new use in Li-ion batteries
  

  Li-ion batteries (LIBs) are widely used in various mobile electronics. Concerns of global warming and climate change have recently boosted the demand for LIBs in electric vehicles and solar photovoltaic output smoothing. Si has been studied as an active material with a high theoretical capacity of 3 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

• 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

• 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
