New Semiconductor Has Promise For 2D Physics And Electronics
2014-03-21 16:13:43

Lynn Yarris, Berkeley Lab From super-lubricants, to solar cells, to the fledgling technology of valleytronics, there is much to be excited about with the discovery of a unique new two-dimensional semiconductor, rhenium disulfide, by researchers at Berkeley Lab’s Molecular Foundry. Rhenium disulfide, unlike molybdenum disulfide and other dichalcogenides, behaves electronically as if it were a 2D monolayer even as a 3D bulk material. This not only opens the door to 2D electronic...

Rotten Egg Gas Now Visible
2013-06-18 16:29:55

Watch the video "Chemical Lights Up Rotten Egg Gas In Body's Cells" Brett Smith for redOrbit.com - Your Universe Online Researchers from Southern Methodist University in Dallas have devised a chemical probe that allows for the visualization of an important process in the human body, the generation of hydrogen sulfide. Best known for its role in producing the “rotten egg” smell associated with certain bodily processes, hydrogen sulfide is also very important for the...

Microwave Oven Used To Cook Up Solar Cell Material
2013-05-06 09:16:00

University of Utah Nanocrystal semiconductor for photovoltaics, medical sensors, heat reuse University of Utah metallurgists used an old microwave oven to produce a nanocrystal semiconductor rapidly using cheap, abundant and less toxic metals than other semiconductors. They hope it will be used for more efficient photovoltaic solar cells and LED lights, biological sensors and systems to convert waste heat to electricity. Using microwaves "is a fast way to make these particles that...

It stinks and strikes fear in the hearts of those who work underground, but the toxic gas hydrogen sulfide may be a lifesaver for patients with heart failure. In a recent study, low concentrations of hydrogen sulfide gas improved functioning in the hearts of mice with heart failure. After heart failure was induced in mice, the gas was administered intravenously once a day for a week. Four weeks after the heart failure event, mice treated with hydrogen sulfide had about a one-third higher...

Chalcocite, copper(I) sulfide (Cu2S), is an important copper mineral ore. It is opaque, being colored dark-gray to black with a metallic luster. It has a hardness of 2½ - 3. It is a sulfide with an orthorhombic crystal system. Chalcocite is sometimes found as a primary vein mineral in hydrothermal veins. However, most chalcocite occurs in the supergene enriched environment below the oxidation zone of copper deposits as a result of the leaching of copper from the oxidized minerals. It is...

Cinnabar (German Zinnober), sometimes written cinnabarite, is a name applied to red mercury(II) sulfide (HgS), or native vermilion, the common ore of mercury. The name comes from the Greek, used by Theophrastus, and was probably applied to several distinct substances. Other sources say the word comes from the Persian zinjifrah, originally meaning "lost". Cinnabar was mined by the Roman Empire for its mercury content and it has been the main ore of mercury throughout the centuries. Some...

Sulfur (or Sulphur; see spelling below) is the chemical element in the periodic table that has the symbol S and atomic number 16. It is an abundant, tasteless, odorless, multivalent non-metal. Sulfur, in its native form, is a yellow crystaline solid. In nature, it can be found as the pure element or as sulfide and sulfate minerals. It is an essential element for life and is found in several amino acids. Its commercial uses are primarily in fertilizers but it is also widely used in gunpowder,...
