Terahertz (THz) frequency radiation has many spectroscopic and imaging applications. Because it suffers from a limited propagation distance in air due to strong water absorption and a historic lack of inexpensive sources, radiation in the THz frequency range has not been commercialized to its fullest extent. Thermal generation of THz radiation is one common source, even though THz frequencies are...
A novel photocatalyst bismuth titanate mixed oxide (BTMO) was prepared by the solvent thermal synthesis method. The structure and morphology of BTMO were characterized by powder X-ray diffraction and scan electron microscope, respectively. Ultraviolet and visible diffuse reflection spectra were measured to account for the photoabsorption properties of BTMO. The tests of photocatalytic activity of...
The Cu6Sn5 intermetallic compound is generated at the interface between OSP substrate and Sn-3.5Ag based solder containing small amount of Co or Ni additives. A small fraction of Co or Ni additive is probed in Cu6Sn5-based crystal structure, which occupies the crystal space sites of Cu atoms. The first-principle approach within the density functional theory is employed herein to explore the favorite...
