Taking into consideration the imaging requirements for this type of application, the refractive index variation over the illuminated volume of the optical material should be better than 10-6, and hence optical elements should be prepared from ultra high purity materials.
By John Colapinto "Was every single element prepared exactly perfectly, technically correct?" M. asked.
Polycrystalline samples of n-type AgIn5Se8 were prepared from the constituent element and employed as electrodes in photoelectrochemical cells.
The NaSi Zintl phase is prepared from the elements by high temperature synthesis.
In this note, we adopted Nd YAG UV 213 nm LA-ICP-MS to determine trace element concentrations of glass beads prepared from a series of geological reference materials (GRMs).
The test solutions were prepared from single-element standard solutions (Inorganic Ventures, Virginia, U.S.A).
Mouse immune genes were identified from our gene expression database constructed using the 8638 element microarray and probed with mRNA prepared from 65 normal adult and fetal tissues.
A Cu-Ci oxygen-evolution catalyst (Ci is inorganic carbonate) is prepared from of the abundant elements copper.
CdSe prepared from Cd and Se elements in the first step was mixed with zinc acetate and sodium sulphide in the second step of milling to prepare a CdSe@ZnS nanocomposite.
However, because of the competition of multiple elements, more Cr is entered into the lattice of alumina prepared from the chromium-containing alumina sludge, and few Fe and Mg elements are entered.
