Aerosol-assisted chemical vapor deposition (AACVD) was used for the first time in the preparation of thin-film electrochromic nickel(II) oxide (NiO). The as-deposited films were cubic NiO, with an octahedral-like grain structure, and an optical band gap that decreased from 3.61 to 3.48 eV on increase in film thickness (in the range 500-1000 nm). On oxidative voltammetric cycling in aqueous KOH ...

The scattering and backscattering properties of bubble populations in the upper ocean are estimated with Mie theory and a generalized bubble size spectrum based on in situ observations. Optical properties of both clean bubbles and bubbles coated with an organic film are analyzed; the results are compared with the corresponding optical properties of micro-organisms of similar size. Given a bubbl...

in order to investigate the effect of temperature and time of blanching process on the generation and extraction of reducing sugars and kinetics of color changes during blanching, the potato strips packaged in the polyethylene (hdpe with 10 micron thickness) film or without polyethylene packaging, were immersed in distilled water at temperature range of 50, 60, 70, 80 and 90 ºc for 120 minutes....

gaz is one of the traditional food products. ingredient of gaz has certain differences compared with other sweets & snacks, which in the preparation of them no oils, starch and flour is used. adverse color, taste and odor in gaz may has been created by oxidation in nuts at store condition. on the other hand, gaz becomes dry in inappropriate packaging at areas with low humidity and becomes soft ...

Heterogeneous "naked-eye" colorimetric and spectrophotometric cation sensors were prepared by immobilization of an azobenzene-coupled receptor onto mesoporous silica (AR-SiO(2)) or titania nanoparticles (AR-TiO(2)) via sol-gel or hydrolysis reactions. The optical sensing ability of AR-SiO(2) was studied by addition of metal ions such as K(+), Ca(2+), Sr(2+), Co(2+), Cd(2+), Pb(2+), Zn(2+), Fe(3...

AIM The aim was to develop an indicator sensor for real-time monitoring of meat quality and to compare the response of indicator sensor with meat quality parameters at ambient temperature. MATERIALS AND METHODS Indicator sensor was prepared using bromophenol blue (1% w/v) as indicator solution and filter paper as indicator carrier. Indicator sensor was fabricated by coating indicator solution...

Grain-finished, high-percentage Charolais steers (n = 36) were selected for uniformity. Immediately after jugular vein exsanguination, 27 steers were infused at 10% of live weight via the carotid artery with a solution developed by MPSC, Inc. (St. Paul, MN) consisting of 98.52% water, 0.97% saccharides, 0.23% sodium chloride, and 0.28% phosphate blend plus either 500 ppm vitamin C (MPSC+C; n = ...

Recently, the coating of thin oxide or nitride film on top of crystals of atomically-thin layered material (ATLM) has been introduced, which benefits optical and electrical properties of the materials and shields them from environmental contact, and has important implications for optoelectronics applications of layered materials. By calculating the reflection contrast, we show the possibility o...
