The excitation spectrum showed that this phosphor can be effectively excited by ultraviolet (UV)(395 nm) and blue (465 nm) light, nicely fitting in with the widely applied output wavelengths of ultraviolet or blue LED chips. The α-Gd2(MoO4)3 phosphor may be a good candidate phosphor for ...
DNA aptamers carrying Pt nanoparticles were prepared by the reaction of DNA aptamers (without functionalization with biotin, thiol, or other reactive groups) with K 2[PtCl 4] in solution at 60-90 degrees C. The DNA-Pt complexes possessed peroxidase enzymatic activity while retaining the specific ...
It is commonly accepted that at low temperature the active phase is crystalline PdO, which may exist in more than one form depending on the oxidized particles size and on the nature of the support, but at high temperature metallic Pd is the active phase for methane oxidation25. In our ...
This paper is a preliminary report on the preparation of silica glass containing very low amount of hydroxyl by the sol-gel processing technique. Gels were prepared from optimized amounts of tetraethyl orthosilicate, fumed silica and water. Acids and bases in small quantities were added for catalys...
The annealing temperature was shown to have a strong effect on the coercivity of the materials, which reaches 650 and 570 kA/m for compositions 1 and 2, respectively. 展开 关键词: Strontium Barium Ferrite Magnetic Composite Strontium Ferrite Glass Crystallization ...
Compared with other methods such as dip-coating, coaxial electrospinning is expected to provide significant advantages in the fabrication of ideal core-shell-type fiber structures, as it can definitely form gaps between the fibers as well as provide pores on the fiber surfaces; besides, it is a...
The molten polymer was then extruded out of the spinning head and drawn by the high-velocity hot air. Simultaneously, the electrostatic field between the frame and the mesh helped attenuate fiber diameter to form microfibers. Finally, the fabric was formed on the collecting mesh. A continuous ...
