This work undertakes the study of the detoxification reactions of O, S-dimethyl phosphoramidithioate (methamidophos) as an organophophorus insecticide on the 14.7 wt% magnetite (Fe3O4) nanoparticles/Ag-NaY faujasite molecular sieve zeolite (FMSZ) composite. The influence of solvent (methanol, acetonitrile and n-hexane) on the detoxification potential of composite was inves...

In retrospective radon measurements, the 22-y half life of (210)Pb is used as an advantage. (210)Pb is often considered to be relatively immobile in glass after alpha recoil implanted by (222)Rn progenies. The diffusion of (210)Pb could, however, lead to uncertain wrong retrospective radon exposure estimations if (210)Pb is mobile and can escape from glass, or lost as a result of cleaning-induc...

mntio3-zeolite-y nanocomposites were synthesized with 5-10-20% (w/w) of mntio3 by stearic acid gel method. then, the gels were calcined at 900 °c for 4 hours and the resulted spectra were investigated at 20% (w/w) concentration. also, the presence of rhombohedral phase of mntio3 in zeolite-y matrix was confirmed by xrd, sem, edx and bet. the vsm results showed the antiferromagnetic properties f...

NaY zeolites with different framework Si/Al ratios were synthesized via hydrothermal technique. Structural characteristics of the synthesized zeolites were determined by using XRD, XRF, SEM, BET analyses. The effects of operating conditions of hydrothermal dealumination, i.e. time, temperature and partial pressure of water vapor on dealumination of the Y zeolites framework and their structure w...

Discharge of organic substances into air has been strongly prohibited since some decades ago, to preserve comfortable natural environment. Though hydrocarbons, alcohols and chlorinated hydrocarbons had been used as the degreasing agent in industries, these solvents may also affect to our environment, and it is necessary to remove them from air as much as possible. This study was performed aimin...

sNN p 1⁄4 5.02 TeV. Events are selected with a dimuon pair produced either in the rapidity interval, in the laboratory frame, 2.5 < y < 4 (p-Pb) or −3.6 < y < −2.6 (Pb-p), and no other particles observed in the ALICE acceptance. The measured cross sections σðγ þ p → J=ψ þ pÞ are 33.2 2.2ðstatÞ 3.2ðsystÞ 0.7ðtheorÞ nb in p-Pb and 284 36ðstatÞþ27 −32 ðsystÞ 26ðtheorÞ nb in Pb-p collisions. We mea...
