the optimization of process conditions for the degradation of acid blue 193 by uv/peroxydisulfate was investigated using response surface methodology (rsm). the effects of four parameters namely initial k2s2o8 concentration, uv irradiation, temperature, and initial dye concentration on two process responses, color removal and the rate constants of the first-order kinetic equations, were investi...

Solid bacterial agents are required to accelerate stover degradation in low-temperature areas. However, the laboratory-to-practice translation of bioprocessing techniques is hindered by high cost, poor practicality, and short shelf life. Using corn powder, starch, bran as additives, we screened Pseudomonas putida Acinetobacter lwoffii, which effectively degrades at low temperatures, develop a s...

Light-induced degradation (LID) in boron-doped Czochralski grown (CZ) silicon is a severe problem for devices such as solar cells or radiation detectors. Herein, CZ investigated by low-temperature photoluminescence (LTPL) spectroscopy. An LID-related peak already found while analyzing indium-doped p-type samples and associated with the ASi–Sii defect model. it whether similar present spectra of...

Dust is a common atmospheric phenomenon in Iran especially in central arid regions.  This severely affects environment as well as resident’s health. Among the results of this phenomenon are Respiratory diseases, bash radiation, accelerated soil erosion, Desertification and degradation of ecosystems. Some dusts are originated from local desert conditions but adjacency to neighboring countries de...
