This work aims to manufacture photodetectors from semiconducting bilayer materials of zinc oxide nanorods and coated with a thin layer CdZnS by chemical bath deposition method. The effect annealing time on the optical electrical properties prepared devices parameters was also studied. films were thermally treated at temperature 200 °C for several times purpose comparison. 15, 30, 35, 60 min, re...

The pulverized lime/limestone injection by top oxygen blowing lance during the basic furnace (BOF) process has gained much interest in recent years due to its advantages helping slag formation and consequently promoting refining reactions such as dephosphorization. In this pneumatic process, understanding motion behavior distribution of powder particles is importance for regulating designing sy...

Electric arc melting of oxide materials under the influence an external electromagnetic field is a high-current and high-temperature technological process, accompanied by powerful electric magnetic fields complex structural motion melt. In general case, movement melt in bath installation determined combination thermocapillary, thermal concentration, convections. this work, based on analysis con...

in the present work the recrystallization behavior of deep drawing grade al-killed low carbon steel sheets produced by mobarakeh steel plant (msp) has been studied. salt bath isothermal annealing has been applied to cold rolled samples and the resulted microstrucrures have been compared with the microstructure obtained from the box annealing process in msp. it is found that at 635 and 700ºc the...

chromate conversion coating is applied on aluminum 6061. the optimum conditions for chromate bath composition and immersion time are also obtained for standard requirements provision such as corrosion resistance in salt spray test, electrical resistance and coating quality. the applied coatings are electrochemically tested in sea and distilled water. according to tafel and cyclic polarization c...

Most rare earth elements (REEs) are critical materials of extreme prominence. Because their criticality, convalescence into metal from oxide (REO) and recycling end-of-life essential for the proficient use safeguard natural resources. With pyrometallurgical approaches using potential versus partial oxidation pressure (E-pO2-) diagrams, conditions making neodymium established by which REOs disso...

The local structures of U(V1) oxide precipitates produced as a function of LiOH concentration have been studied by XAFS. Curve-fitting analyses indicate that the solid formed in 0.1 M LiOH is similar to a schoepite-like phase where distinct linear uranyl ions (UO?) are bridged along the equator by OH ions. At higher LiOH concentrations, the uranyl groups become elongated and the precipitate str...
