the our main goal of the present research is evaluating the performance of mno2 nanoparticles-agx zeolite composite as a novel adsorbent catalyst for the decontamination reactions of two most known sulfur mustard simulants; 2-chloroethyl phenyl sulfide (2-ceps), 2-chloroethyl ethyl sulfide (2-cees) at room temperature and monitoring by gas chromatography flame ionization detector (gc-fid) and g...

Nickel doped TiO2nano particles (1% w/w) were prepared and immobilized on NaX zeolite and after characterization by X-ray diffraction and scanning electron microscopy used as photo catalyts for degradation of orange G. The X-ray diffraction patterns show that the supported TiO2 are crystallized in anatase form and the intensity of the zeolite peaks decreases with the incre...

Sulfur-containing organic and inorganic compounds are the main harmful component of natural gas oil, as well products their processing. Since sulfur have acidic properties, content leads to corrosion technological parts in production processes. The hydrogen sulfide transported should not exceed 20 mg/m3. In Uzbekistan, motor vehicles run mainly on liquefied gas. Sulfur corrode cylinders, result...

1. Introduction Pulsed Field Gradient (PFG) NMR has proved to be a valuable tool to probe the intracrystalline diffusion of molecules adsorbed in microporous materials [1]. It is well-known that the purely intracrystalline diffusivity D intra can only be attained, if the root mean square (rms) displacement of the molecules during the observation time is much smaller than the diameter of the cry...

Nax is a sodium-concentration ([Na+])-sensitive Na channel with a gating threshold of ~150 mM for extracellular [Na+] ([Na+]o) in vitro. We previously reported that Nax was preferentially expressed in the glial cells of sensory circumventricular organs including the subfornical organ, and was involved in [Na+] sensing for the control of salt-intake behavior. Although Nax was also suggested to b...

23Na MAS, 2D nutation MAS, and DOR NMR spectroscopy has been applied to characterise the location of sodium cations in dehydrated zeolite NaX (Si/Al = 1.23). The 23Na MAS NMR spectra recorded at three different magnetic field strengths were decomposed by computer simulation into five lines, which were attributed to five crystallographically distinct cation sites known from X-ray diffraction stu...

In the preceding companion article, we reported high-temperature molecular dynamics (MD) simulations to trace single-molecule as well as collective mean square displacements over a range of temperatures (6001500 K) and loadings (infinite dilution to four benzenes per supercage) to evaluate respectively the selfdiffusivities and cooperative (alternatively Maxwell-Stefan) diffusivities of benzene...
