the heterogeneous photo-fenton degradation of crystal violet under visible light has been investigated usingcopper modified iron oxide. the photocatalyst has been prepared by coprecipitation method. the rate ofphotocatalyic degradation of dye was monitored spectrophotometrically. it has been observed thatphotocatalytic degradation follows pseudo first order kinetics. the effect of various param...

background methamphetamine (ma) is a highly addictive stimulant which has destructive effects. there is also evidence that methamphetamine use in some females, partly is due to their desire to lose weight. the purpose of this study was to determine the association between family flexibility, food preoccupation and body image among crystal abuser women. objectives this study tried to evaluate wh...

the clay crosslinked hydrogel nanocomposites were synthesized by graft copolymerization of acrylamide and itaconic acid in the presence of different amounts of laponite using ammonium persulfate and n,n,n',n'-tetramethylethylene diamine  )temed) as a free radical initiator and catalyst, respectively. the xrd patterns of nanocomposites showed that the clay layers are completely exfolia...
