The compound (n-Bu4N)2Tc2Br8 was prepared by the metathesis of (n-Bu4N)2Tc2Cl8 with HBr (g) in dichloromethane and characterized by X-ray absorption fine structure spectroscopy and UV-vis spectroscopy. Analysis of the data gives a Tc-Tc distance of 2.16(1) A and a Tc-Br distance of 2.48(1) A. The Tc(III) oxidation state was inferred by the position of the edge absorption, which reveals a shift ...

UNLABELLED Pure zinc oxide and zinc oxide/barium carbonate nanoparticles (ZnO-NPs and ZB-NPs) were synthesized by the sol-gel method. The prepared powders were characterized by X-ray diffraction (XRD), ultraviolet-visible (UV-Vis), Auger spectroscopy, and transmission electron microscopy (TEM). The XRD result showed that the ZnO and BaCO3 nanocrystals grow independently. The Auger spectroscopy ...

The feasibility of identifying habitat of sulfur fumigated Radix Astragali and of determining its sulfur dioxide residue using UV-vis and short wave near-infrared diffuse reflectance spectra coupled with chemometrics was first investigated. The results show that by using UV-vis-SWNIR DRS combined with PCA, the habitat of Radix Astragali is identified definitely, whether it is sulfur-fumigated, ...

There are many chemical molecules whose names are Cannabigerol (CBG), cannabidol (CBD), cannabichromene (CBC), tetrahydrocannabivarin (THCV), cannabigerovarinic acid (CBGV) and cannabidiolic acid (CBDA) derived from Marijuana. Theoretical methods were used to compare the chemical and biological activities of the six major molecules. Molecules were compared with their chemical activities using m...

Observations of ozone from satellite platform is a key source of information to monitor and understand processes that may have a relevant impact on public health, air quality and climate. To achieve at the same time a reasonable spatial resolutions and a sufficient sensitivity, nadir UV/VIS sensor may be exploited. The topic of the PhD thesis work summarized here is the use of neural networks (...

Three new open-framework aluminoborates (ABOs), Rb2AlB5O10·4H2O (), [C5N2H16]AlB5O10 (, C5N2H16 = N-ethyl-1,3-diaminopropane) and [H2dap][(CH3)2NH]AlB5O10 (, dap = 1,2-diaminopropane) have been made under solvothermal conditions and characterized by elemental analysis, IR, TGA, UV-vis, powder XRD, single-crystal XRD, fluorescence spectra and NLO determination, respectively. These three ABOs dis...

ZnS nanoparticles of different size have been synthesized using a colloidal particles method. ZnS nanoparticles prepared with capping agent (mercaptoethanol) then were characterized using X-ray diffraction (XRD) and UV-Vis spectroscopy. The particle size of the nanoparticles calculated from the XRD patterns has been found in the range 1.85-2.44nm. Absorption spectra have been obtained using UV-...

the reduction capacity of ammonia while present even at ppm level can be demonstrated by the increased encounter probability between ammonia and methylene blue dye (mb+) incorporated in nanomordenite and na-mor zeolites. the rate of reduction methylene blue dye by ammonia on the surface nanomordenite zeolite is faster than na-mordenite (na-mor) zeolite.because nanomordenite zeolite with high si...
