High

2013/2/19The phase transition, amorphization, and crystallization behaviors of the topological insulator bismuth selenide (Bi 2 Se 3) were discovered by performing in situ high-pressure angle-dispersive x-ray diffraction experiments during an increasing, decreasing, and recycling pressure process.

Vadim Evgenievich Lashkaryov (October 7, 1903 – December 1, 1974), a prominent Soviet experimental physicist, was born in Kyiv, currently the capital of Ukraine, to a family of a lawyer.He was an Academician of the National Academy of Sciences of Ukraine and is known for his fundamental contributions to physics of semiconductors Get price

Recent publications

In experiments, synthesized Bi 2 Se 3 is often heavily n-type doped due to selenium vacancies. Furthermore, it is discovered from experiments on bulk single crystals that Bi 2 Se 3 gets additional n-type doping after exposure to the atmosphere, thereby reducing the relative contribution of Get price

Mechanically induced amorphization of small molecule

2019/7/23We present a multiscale framework to predict mechanically induced amorphization without experimental information. The model requires as input only the molecular structure and starts with molecular dynamics simulations to determine elastic constants, melting temperature, crystal-amorphous interface energy, and the energy density difference between the amorphous and crystalline phases.

Amorphous

amorphous - Something amorphous has no real shape or is irregularly shaped—like pudding; an amorphous solid lacks the perfect ordered structure of crystals. He was supremely happy, perched like an amorphous bundle on the high stool, with his head thrown back, his eyes fixed on the opposite cornice, and his lips wide open, sending forth, with all his might, impromptu syllables to a tune Get price

Landfill is underrated and recycling overrated

There are some PV technologies that use rare elements such as indium and selenium, but they do not use rare-earth elements either; and, in any case, they have been pretty much priced out of the market by falling polysilicon costs. There are many kinds of Get price

Using Cytochrome c3 To Make Selenium Nanowires

We report on a new method to make nanostructures in aqueous solution at room temperature. We used the protein cytochrome c3 to catalyze reduction of selenate (SeO42-) to selenium Se0 by dithionite. Reduction was instantaneous. After a week spherical nanoparticles of red Se0 (about 50 nm diameter) precipitated, followed by self-assembling into crystalline nanowires, typically 1 μm long.

Antioxidants

Antioxidants interact with free radicals, terminating the adverse chain reactions and converting them to harmless products. Antioxidants thus minimize the oxidative stress and play a crucial role in the treatment of free radicals-induced diseases. However, the effectiveness of natural and/or synthetic antioxidants is limited due to their poor absorption, difficulties to cross the cell Get price

Copper

Copper does not react with water, but it does slowly react with atmospheric oxygen to form a layer of brown-black copper oxide which, unlike the rust that forms on iron in moist air, protects the underlying metal from further corrosion (passivation).A green layer of verdigris (copper carbonate) can often be seen on old copper structures, such as the roofing of many older buildings and the Get price

Amorphous silicon

Amorphous silicon (a-Si) is the non-crystalline form of silicon used for solar cells and thin-film transistors in LCDs. Used as semiconductor material for a-Si solar cells, or thin-film silicon solar cells, it is deposited in thin films onto a variety of flexible substrates, such as Get price
