In order to cleanly and efficiently extract zirconium from zircon sand (the main component is ZrSiO4), sodium hydroxide sub-molten salt was used to decompose ZrSiO4 in this study. When ZrSiO4 reacts with sodium hydroxide sub-molten salt, the formatio

Yttria-stabilized zirconia (YSZ) has been widely used in structural and functional ceramics because of its excellent physicochemical properties. In this paper, the density, average gain size, phase structure, and mechanical and electrical properties

The demand for low resistance metallization solutions has become an increasingly important issue as interconnect line sizes have approached and in some cases become smaller than the electron mean free path in Cu. Formation of reliable small damascene

Different gases have been successfully fingerprinted on the basis of the distinct transition frequencies measured by frequency tuning a THz source developed by us. Our further analysis illustrates that one can reliably separate isotopologues by measu

We have identified 68 rotational transitions from three isotopic variants of nitrous oxide, among which 29 were never observed previously. By deducing and comparing the rotational constants, we have reliably differentiated among three isotopic varian

We demonstrate that a widely-tunable far-IR source developed by us recently can be used to identify weak inversion and inversion-rotational transitions within the nu2=1 excited state of NH3 molecule. Seven transition peaks have been observed.

The transmission spectra of two CO isotopic variants, i.e., (12)CO and (13)CO, are measured with a recently developed widely tunable THz source. The pure rotational transition lines of J=6 --7, 10 --11, 11 --12, 12 --13, and 13 --14 have been identif

Using the widely-tunable monochromatic THz source developed by us recently, we have directly measured the transmission spectra of a few diatomic and triatomic molecules in the THz region. In addition, using the FTIR acquired from Bruker Optics, we ha
