Based on the particle linear depolarization ratio (PLDR) and single-scattering albedo (SSA) values obtained for 1020 nm from Aerosol Robotic Network (AERONET) Version 3 Level 2.0 data collected in five regions, namely, northern China, Northwest Asia, Tibetan Plateau, southern China Southeast we classified seven types of aerosol (viz., purely dust, dust-dominated, pollution-dominated, non-absorb...

Twenty-one Lori–Bakhtiary sheep were randomly allocated into 3 groups to compare the effects of oral selenium nano particles (Se NPs) and sodium selenite (Na-Se) supplementation on serum selenium, copper, zinc, molybdenum, manganese and cobalt concentration. Groups 1 and 2 orally received Se NPs and Na-Se (1 mg/kg) for 10 consecutive days, respectively ...

Microchemical glass standards were used to validate a quantitation method based on peak-to-background (P/B) ratios from electron probe x-ray microanalysis spectra. This standardless method was applied to the determination of concentrations of individual particles from Malpha or Lalpha lines, as well as from Kalpha lines. The algorithm was tested on particulate glass samples for diameters rangin...

The influence of impurities on the N NQR lineshape of Na1_^AgcN02 and [NaN02],_,[BN03]^ (B = Na, K) at room temperature has been investigated. Carrying out spectral analysis in conjunction with classification of the local field inhomogeneities according to the structurally isomorphic, Na]_xAgxN02, and anisomorphic [NaNO^.JBNC^b systems, enabled an understanding of the microscopic nature of impu...

Nano thin film materials play an indispensable role in modern electronics and other field of material sciences especially a photovoltaic technology. The scope this research is to grow Zinc Sulphide (ZnS) characterize structurally understand the benefits study choosing chemical deposition method (The aerosol spray pyrolysis), combination analysis annealing temperature. Specifically on strength i...

Marine stratocumulus clouds often become decoupled from the vertical layer immediately above the ocean surface. This study contrasts cloud chemical composition between coupled and decoupled marine stratocumulus clouds for dissolved nonwater substances. Cloud water and droplet residual particle composition were measured in clouds off the California coast during three airborne experiments in July...

A method for producing high surface area nano-sized mesoporous alumina from inexpensive Iranian kaolin as raw material is proposed. In this method, first, kaolin was purified for purifying Kaolin, High Grade Magnetic Separation and leaching with HCl and chemical bleaching treatment by using sodium dithionite (Na 2 S 2O4 ) as reducing agent in acidic media (H 2SO 4 ) were used. Pur...

it is very important to determine the stable nitrogen isotope ratio for the nitrogenous substances in aerosols and the geochemistry behavior of stable nitrate ion isotopes in aerosols in order to elucidate the chemical and physical functions of clouds. hence, aerosol field sampling was conducted in the skies offshore from malibu beach and santa barbara, california, u.s.a. on 16 and 18 july 2009...
