Bismuth therapy has shown efficacy against two majors gastrointestinal disorders: peptic ulcer disease and diarrhea. It is as effective as the H2-receptor antagonists in peptic ulcer disease, costs considerably less, and offers a lower relapse rate. ...…
What is Bisthmuth?Bisthmuth is a dark gray or black powder composed of nearly spherical particles of bismuth of under 100nm in diameter; bismuth powders see usage in various fields, including manufacturing, metallurgy, and countless specialty applica...…
The Ti-doped Bi 2 Te 3 with concentrations 1, 3, and 5 in % Ti were synthesized using a simple powder metallurgy method. It is revealed that the optimum Ti addition in parent material changes the conduction type from undoped n-type into p-type with 1...…
In 1821, T.J. Seebeck discovered the Seebeck effect when he noticed that a compass needle was deflected when a metal was heated with a heat gradient. He called the effect thermomagnetism. Oersted later redefined it when he observed that an electric c...…
Eighteen years before anyone understood what an electron was or that they existed, back when the current was thought to be an incompressible fluid, Edwin Hall, while working on his dissertation, discovered that when applying a current along a thin go...…
An experimental investigation of the electronic transport properties of bismuth telluride nanocomposite materials is presented. The primary transport measurements are electrical conductivity, the Seebeck coefficient, and the Hall effect. An experimen...…
Bismuth telluride (Bi2Te3) is a gray or black hexagonal platelet with a metallic luster or gray powder. It is an alloy of two metallic elements (Bismuth and tellurium), also known as Bismuth (III) telluride. When alloyed with antimony or selenium, it...…

The electronic transport properties vary significantly with alloy composition. Pisarenko plot fits of Seebeck versus Hall carrier concentration using a single valley effective mass model assuming potential deformation scattering find that the Seebeck...…
Bismuth telluride, bismuth selenide, and all intermediate alloys Bi2Te3−xSex have the tetradymite crystal structure in the symmetry group R3¯m. The material is comprised of repeating quintuple layers of X(1)–Bi–X(2)–Bi–X(1), where the number in paren...…
The n-type Bi2Te3-Bi2Se3 alloy is less straightforward. Mass contrast alloy scattering modeling does not match thermal conductivity values reported in the literature, and there is wide variability in qualitative trends reported. The electronic band s...…
Bismuth telluride is the dominant thermoelectric material for applications near room temperature due to its inherently low lattice thermal conductivity and high electronic weighted mobility. Its performance is ultimately limited by the harmful effect...…
A vanadium aryl hydride gel was prepared by thermal decomposition and subsequent hydrogenation of tetraphenyl vanadium and evaluated for electrochemical and hydrogen storage performance. Characterization by IR, XRD, XPS, nitrogen adsorption, and TGA ...…
EDEP can be used to disperse, defoam, or in other formulations. The Ethylenediamine block polyether polyoxypropylene and polyoxyenthylene: EDEP can be used to disperse, defoam, or in other formulations. It is a global trusted brand Ethylenediam...…
Modern industry cannot function without ultrafine alumina. Alumina powders with ultrafine or fine grain have a different surface electronic structure, and the crystal structure has also changed. This leads to surface effects, and smaller sizes, that ...…
