Silicon Products Bitterfeld GmbH & Co.KG (SPB) operates in Bitterfeld-Wolfen (close to city of Leipzig), Germany, a large-scale silicon production plant. The sale of Silicon Products Bitterfeld GmbH & Co KG from PV Crystalox Solar Silicon GmbH to Silicon Products Research Engineering Production Gmb more
By inerting with SilcoNert 2000 you prevent the adsorption of active components on reactive surfaces and make your trace analysis more precise more
In addition to Ampere, Kelvin, Mol and Co., the kilogram also is now defined by a natural constant. In concrete terms, this means that the original kilogram, which has been the measure of all things for 130 years, has now served its purpose in Paris. This is made possible by the single crystals grow more
Daimler AG has acquired a minority equity stake in U.S. battery material specialist Sila Nanotechnologies Inc. (Sila Nano) as part of its research and development activities. Founded in 2011, Sila Nano is a leading developer of new battery materials, which outperform existing lithium-ion technologie more
Longer lifetimes, larger ranges and faster recharging - developments such as electric mobility or the miniaturisation of electronics place new requirements on rechargeable batteries. With its enormous storage capacity, silicon has decisive advantages over the materials used in commercially available more
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
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
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
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
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
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
Polysilicon has a major influence on its end markets - Semiconductor and Photovoltaic industry. Polysilicon is the substrate upon which primarily all semiconductors are manufactured. Polysilicon is an important component for silicon-based solar cells. Consumption of solar industry grew more than its more
Silicon metal is used by the chemical and aluminum industries as a key input or raw material into large number of consumer and industrial products, which range from cosmetics, sealants, computer chips to solar panels. Worldwide silicon metal market entered an average-growth phase in 2010, in respons more
Chemplast Sanmar Limited (Chemplast Sanmar) engages in manufacturing and sale of chemical products. Chemplast Sanmar is a subsidiary of the Sanmar Group. Chemplast Sanmar's product portfolio includes PVC, caustic soda, chlorine, silicon wafers, refrigerant gases, methylene chloride, chloroform, T more
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
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
