The chemical treatment of wood has been shown to increase its mechanical strength by forming composites with a variety polymers. Polyethylene glycol diacrylate (PEGDA) commonly used as polymer reinforcement the and resistance spruce for various applications, such protection from weathering. In this study, PEGDA was impregnated into samples polymerized dielectric barrier discharge (DBD) plasma f...

background : staphylococcus aureus strains exhibiting multiple antibiotic resistances are isolated from most communities and hospital infections. treatment of patients with these infections has been difficult. the aim of this study was to detect and extract, the egg yolk immunoglobulin y as a potential source of anti- s. aureus antibody. methods : specific igy was produced by immunizing hens wi...

This study presents a multi-walled poly(ethylene glycol) diacrylate hydrogel tube formed by the simple self-folding of a bi-layered hydrogel patch. The gel tube has the capability to release encapsulated molecules through designated pathways in a sustained manner. Therefore, the gel tube encapsulating the vascular endothelial growth factor significantly increases the vascular densities and vess...

abstract in order to study the effect of using somaclonal variation on production of resistant lines to water deficit conditions on carrot (daucus carota l.), an experiment was carried out in department of biotechnology of all russian research institute of vegetable crops (raas) in 2008-2009. coated seeds of four carrot cultivars which are cultivated in iran including, monarch, nantes improved,...

objective: due to recent advances in nanotechnology it is now possible to accumulate high atomic-number nanomaterial such as gold nanoparticles (gnps) in cancerous cells and take advantage of their absorbed dose enhancement property as radiosensitizing agents. this study aimed to investigate the absorbed dose enhancement factor due to the presence of pegylated gnps under the irradiation of an m...

pigeonpea (cajanus cajan (l) millsp.) is a drought tolerant legume widely grown in the arid and semi-arid tropics of the world which possesses a deep and extensive root system that succors a number of important physiological and metabolic functions to cope with drought. application of available functional genomics approaches to improve productivity under water deficit requires a better understa...

An efficient and green procedure for the synthesis of 2, 4, 6-triaryl-1H-imidazole in polyethylene glycol under microwave irradiation in excellent yield has been developed. Polyethylene glycol is non toxic, reusable, inexpensive and easily available.

polyethylene glycol was easily grafted to silica gel and used as a solid–liquid phase transfer catalyst in the reduction of aromatic nitro compounds. this silica-grafted polyethylene glycol is proved to be an efficient heterogeneous catalyst in the reduction of nitroarenes to the corresponding aromatic amines with zinc powder in water. the reduction reactions proceeded efficiently with excellen...
