After synthesizing Ag nanoparticles and loading onto activated carbon (from olive stone), the adsorption of methyl orange (MO) onto the prepared nanoparticles was studied. In this connection, the effect of experimental parameters such as pH range, reagent concentration, contact time, dosage amount of adsorbent and so on, on the adsorption process were studied. The experimental results were anal...

Motivation: Children with systemic juvenile idiopathic arthritis (SJIA) are affected by a wide-range of complications. Partially arising from the difficulty of diagnosis due to the idiopathic nature of the indication. There may be a genetic basis for SJIA, which could help in both diagnosis, and treatment. Results: Two mutations in the Fc epsilon RI pathway, including PIK3CD, were detected in l...

Excessive amount of dyes in the discharged wastewater from textile industry becomes a severe problem water pollution due to presence unruly toxic organic compounds. Dyes are highly and carcinogenic compounds that cause extremely harmful effects on human health. The adsorption method is considered one best methods for dye removal because its availability, low cost, stability, large surface area ...

In this study, lignin was isolated from rice (Oryza sativa L.) husk using alkaline extraction method and used as an adsorbent for aqueous solutions of methyl orange (MO) bromothymol blue (BTB). The equilibrium removal rate MO found to be at 61.4%, with experimental adsorbate uptake, qe, 1.23 mg·g-1, achieved 150 minutes contact time. For BTB, the 78.3%, qe 1.57 Pseudo-first order (PFO) pseudo-s...

A organic-solution-processable functionalized-graphene (SPFGraphene) material has been studied on pre-concentration and determination of trace Mo(II)ions. In this process, the effects of pH solution, elution conditions on pre-concentration of trace Mo(II) were studied and the effect of interfering ions was also investigated. A selective method for the fast determination of trace amounts of Mo (...

We demonstrate an AlN/AlGaN high-electron-mobility transistor (HEMT) fabricated on a free-standing AlN substrate. A metal stack, composed of Zr/Al/Mo/Au, was found to show low contact resistivity for source and drain ohmic contacts. The fabricated AlN/AlGaN HEMT exhibited a maximum drain current of 38 mA/mm with a threshold voltage of -3.4 V. Negligible drain current degradation was observed at...

conclusions our results showed that mo extract may have a gastroprotective effect against experimental gastric ulcers in rats. the exact mechanism has not yet been determined, but it may be due to enhancing enzymatic antioxidant defenses and inhibiting lipid peroxidation. materials and methods male wistar rats (200 - 250 g) were starved for 24 hours prior to the induction of gastric ulceration ...
