The chemical looping reforming (CLR) process, which utilizes a transition metal oxide based redox catalyst to partially oxidize methane to syngas, represents a potentially efficient approach for methane valorization. The CLR process inherently avoids costly cryogenic air separation by replacing gaseous oxygen with regenerable ionic oxygen (O(2-)) from the catalyst lattice. Our recent studies sh...

objective(s): organic cation transporter 3 (oct3) as a high-capacity transporter contribute to the metabolism of metformin. the present study was conducted to determine the genotype frequencies of the variant oct3-1233g>a (rs2292334) in patients with newly diagnosed type 2 diabetes (t2d) and its relationship with response to metformin. materials and methods: this study included 150 patients wit...

polycyclic aromatic hydrocarbons (pahs) are one of the most important organic pollutants frequently found in the environment. in this experiment, the effect of phytoremediation as a cost effective method was studied on the concentration of anthracene (c14h10) which is one of pahs. the effect of sorghum (v1), hairy vetch (v2) and oat (v3) was studied under four concentrations of anthracene (s1, ...

Hexavalent chromium is highly toxic to most living organisms and a known human carcinogen by the inhalation route of exposure. Therefore, treatment of Cr(VI) contaminated wastewater is essential before their discharge to the natural water bodies. Cr(VI) reduction to Cr(III) can be beneficial because a more mobile and more toxic chromium species is converted to a less mobile and less toxic form....

The synchronous homopolar motor (SHM) with an excitation winding on the stator and a toothed rotor is good alternative to traction induction motors for hybrid mining trucks. main problem in design of SHM electric drives that magnetic flux forms three-dimensional loops and, as result, lack high-quality optimization methods, which leads need overrate installed power inverter. This article discuss...
