We have studied the diversity and specificity of interactions of amphibactin produced by Vibrio genus bacterium (Vibrio sp. HC0601C5) with iron and various metal ions in + 3 oxidation state in an octahedral (Oh) environment. To survive in the iron-def
In the case of TiO2_HSAc500-Pt sample the photocatalytic activity increased after the deposition of platinum under both visible and UV light irradiation. The photocatalytic activity gain – in the case of visible light irradiation – could be attributed to the rutile content of the sample, since...
The open circuit voltage Voc of piezoelectric material is calculated by;(3)VOC=dijεrε0σijgewhere σij is the applied stress, dij is the piezoelectric coefficient, ge is the distance between the top and bottom electrodes, εr is relative dielectric constant, and ε0 is the permittivity. ...
In order to get the hydrogen gas into solution a Teflon-bonded platinum black catalyst is used, similar to that used in fuel cells. This platinum electrode has the added advantage that it can recombine oxygen with hydrogen extremely fast. Since the only bad chemical reaction during over charge...
the precious metals such as platinum, palladium, ruthenium, rhodium, and the like, and the precious metals plated onto other metals, such as, for example, titanium and tantulum. The precious metal type anodes, however, suffer from the disadvantages of being relatively expensive and somewhat susce...
a) preparing a solution of carfilzomib in methanol; b) isolating the amorphous carfilzomib. In an aspect, the present invention provides a HPLC method for analysing carfilzomib, wherein the mobile phase comprises first liquid A and a second liquid B, and the relative concentration of the liquids...
In the sensing mechanism, multiple micro-hair structures used as micro-switches respond to air flows (Figure 17A).As represented in Figure 17A, the micro-hairs are printed at an offset of 45 μm from the common contact terminal (platinum wire with 160 μm diameter) of the adjacent micro-...
in the studies focusing on the atomic composition ratio, the field-effect mobilities in the range 0.5–10.0 cm·V−1s−1 were controlled by varying the ratio of In:Zn or In:Zn:Ga, and the thickness, roughness, and crystallinity of the semiconductor film were investigated relative to the...
At present, most of the four-wire platinum resistance is used to measure temperature. The resistance value and temperature of the platinum resistance temperature sensing element are close to the linear relation in a fairly wide temperature range, the precision is high, the stability is good,...
