Traditionally, manufacturers have used one of three common semiconductor materials: germanium, silicon, and gallium arsenide. Go in depth on semiconductor materials. Discovered in 1886, germanium was the "original" semiconductor. However, germanium fell from grace after manufacturers realized silicon cost significantly less.

May 31, 2021 · A thorough exploration of the configurational space of gasphase Pt n + and GePt n−1 + (n=5–9) clusters using global minima search techniques and the subsequent electronic structure analysis reveals that germanium doping reduces the binding strength .

The organogermanium compound 3(trihydroxygermyl)propanoic acid (THGP) has various biological activities. We previously reported that THGP forms a complex with cisdiol,4Dihydroxyphenylalanine (LDOPA), a precursor of melanin, contains a cisdiol structure in its echol skeleton, and excessive melanin production causes skin darkening and staining.

The NIST Quantitative Infrared Database currently consists of a collection of absorption coefficient spectra of volatile organic compounds. These spectra were measured from primary gas standards prepared and verified at NIST. Spectra are provided in 5 resolutions from cm −1 to cm −1 using 5 apodization functions.

Aug 06, 2020 · 6. 3 M Young Scientist Lab. Heat Energy Virtual Lab. These are seriously cool and I wish they offered more than 6 choices. During our energy unit, I love to use the Wind Energy interactive. Students design, build, and test wind turbines as they try to power 400 homes for the cheapest price.

Jul 22, 2000 · An efficient synthesis of chlorogermane linker 12 is described. Economic introduction of germanium into this linker is accomplished by insertion of dichlorogermylene [from germanium(IV) chloride] into the homobenzylic C−Cl bond of 4(2chloroethyl)phenol 1. Using linker 12, transmetalation with lithiated 4acetophenone, 3acetophenone, and 4(4'methoxy)biphenyl followed by Mitsunobu .

Organic Germanium is found naturally in mushrooms, Allium sativum, Allium cepa, Panax ginseng, Pfaffia paniculata. Organic and inorganic forms of Germanium. In its inorganic from Germanium is present in the soil, rocks and coal, together with other minerals from which it can be extracted and transformed industrially into organic Germanium.

Sep 01, 2005 · Cultures supplemented with 60 mg l −1 organic germanium enhanced both fresh (565 ± 6 g) and dry (44 ± 2 g) biomass accumulations of adventitious roots and accumulation of Rb and Rg group of ginsenosides. This is the first report on organic germanium as an elicitor for ginsenoside accumulation in plant cell cultures.

On 1 May 2014 a paper published in Phys. Rev. Lett by J. Khuyagbaatar and others states the superheavy element with atomic number Z = 117 (ununseptium) was produced as an evaporation residue in the 48 Ca and 249 Bk fusion reaction at the gasfilled recoil separator TASCA at GSI Darmstadt, Germany. The radioactive decay of evaporation residues and their αdecay products was studied .

The organic germanium compounds present in panaxel and panaxel5 did not potentiate the anticarcinogenic or immuno stimulatory effects as much as biogeinseng. Preliminary clinical trials with panaxel and bioginseng were carried out in patients with precancerous lesions of the esophagus and endometrium. Panaxel was found to have a strong ...

Nanocrystalline germanium thinfilms deposited on glass by plasmaenhanced chemical vapor deposition from germane and hydrogen were doped with phosphorus and boron. We report some electrical transport and structural properties of Ge films as a function of dopant species and doping levels.

Germanium is a chemical element with the symbol Ge and atomic number 32. It is a lustrous, hardbrittle, grayishwhite metalloid in the carbon group, chemically similar to its group neighbors silicon and germanium is a semiconductor with an appearance similar to elemental silicon. Like silicon, germanium naturally reacts and forms complexes with oxygen in nature.
