The detection of light helicity is key for various applications, from drug production to optical communications. However, the direct measurement inherently impossible with conventional photodetectors based on III–V or IV–VI non-chiral semiconductors. prior polarization analysis by often moving elements necessary before sent detector. A method here presented effectively give dilute nitride GaAs-...

Huan Thermal conductivity (K) and thermal diffusivity (a) are two important physical properties essential for designing any food engineering processes. Recently a new transient plane-source method was developed to measu...

Yttria-stabilized zirconia (YSZ) is one of the primary choices for the electrolyte material in solid oxide fuel cells (SOFC), due to its excellent ionic conductivity at high temperatures. Nevertheless, such performance is usually limited by the ionic conductivity at grain boundaries, which is at least two orders of magnitude lower than that of bulk [1]. As a result, many studies have been perfo...

We describe the general aspects of ion chromatography and how on-line counted ion-exchange techniques can be utilized to determine pyruvic and lactic acids in plasma and vanillymandelic acid in urine. Pyruvate and lactate are extracted from deproteinized plasma by use of an ion-exclusion resin. After elution from the resin, the plasma extract is chromatographed on an anion-exchange column, with...

Amorphous molybdenum silicide compounds have attracted significant interest for potential device applications, particularly in single-photon detector. In this work, the temperature-dependent resistance and magneto-resistance behaviors were measured to reveal charge transport mechanism, which is of great importance applications but still insufficient. It found that Mott variable hopping conducti...

The present paper deals with the development and validation of analytical method based on a single column high performance Ion chromatography with cation suppressed conductivity detection, developed for quantitation of tartaric acid. The diluent used for the preparation of sample solution was water and injected into a standard chromatographic system connected with 250mm length, 4.0 mm ID and 5....
