poly n-isopropylacrylamide was successfully grafted onto a polystyrene cell culture dish by gamma ray. in this study, the effect of a radiation dose (radiation absorbed dosages of 10, 20, 30, 40 kgy) under appropriate temperature and grafting conditions was investigated. the ftir analysis showed the existence of the graft pnipaam on the substrate. the optimal value of the dose for grafting was ...

Abstract Mefenamic acid is a nonsteroidal anti-inflammatory drug (NSAID) that has analgesic,anti-infammatory and antipyretic actions. It is used to relieve mild to moderate pains. Solid-phase extraction of mefenamic acid by a polymer grafted to silica gel is reported . Poly allyl glycidyl ether/iminodiacetic acid-co-N, N-dimethylacrylamide was synthesized and grafted to silica gel and was used ...

the current experiment was carried out to evaluate qualitative and quantitativeof three melons (cucumis melo gp. ameri) accssions named zardjalal, ananasi and khanoti. the experiment was conducted in a randomized complete block design (rcbd) with 16 treatments and three replications at research field of jahad-e-daneshgahi, campus of agriculture and natural resources, university of tehran. five ...

background: flexural strength of prosthesis made with dental composite resin materials plays an important role in their survival. the aim of this study was investigating the effect of nanoclay fillers and poly (methyl methacrylate)-grafted (pmma-grafted) nanoclay fillers loading on the flexural strength of fiber-reinforced composites (frcs). materials and methods: standard frc bars (2 × 2 × 25 ...

the effect of grafting on yield and some other quantitative and qualitative characteristics of two green¬house cucumber cultivars, namely roberto and danito grafted on five rootstocks of shintoza, kiroshintoza (cucurbita maxima × c. moschata), cucurbita maxima (c. maxima cv. goriki), fig leaf gourd (c. ficifolia cv. korodome), and bottle gourd (lagenaria siceraria) was investigated in this stud...

in this study, a landrace melon zarde jalali as the scion and commercial varieties of cucurbita rootstocks cv., shintozwa and ferro-rz was used as the rootstock. grafted plants upon commercial varieties of cucurbita with own-rooted and ungrafted at three irrigation levels of 60, 80 and 100% (respectively 4984.32, 6124.82 and 7239.41 m3ha-1) based on total available water depletion with drip irr...

By employing coarse-grained molecular dynamics simulation, we simulate the spatial organization of the polymer-grafted nanoparticles (NPs) in homopolymer matrix and the resulting mechanical performance, by particularly regulating the grafted chain length and flexibility. The morphologies ranging from the agglomerate, cylinder, sheet, and string to full dispersion are observed, by gradually incr...
