Abstract We investigate the effect of highly contrasting non-Newtonian liquid properties on formation jets with a focused shape. By using two nozzle-free ejection techniques, mechanically impact- and laser-induced, fast elastic (sodium polyacrylate) weakly (xanthan-gum) diluted polymer solutions are generated. A unique high-speed is encountered at jet onset solution. Its jet-tip speed average 1...

A new procedure is described for surface grafting polymer brushes by step-growth polymerization from initiator-embedded polymeric thin films and micron- and nanometer-scale patterns. An imprint lithographic process, nanocontact molding, was used to prepare thin patterned cross-linked polyacrylate network films on silicon wafers that incorporated 4-bromostyrene in the networks. These networks pr...

Curcumin is a yellow polyphenol with multiple medicinal effects. These effects, however, are limited due to its poor aqueous stability and solubility. A hydrogel of 3% octadecyl randomly substituted polyacrylate (PAAC18) has been shown to provide high aqueous stability for curcumin under physiological conditions, offering a route for photodynamic therapy. In this study, the excited-state photop...

impurities of drug substances may produce some side effects in patient. diclofenac na is a member of non-steroidal anti inflammatory drugs (nsaids) family, which is routinely used by patients for the treatment of rheumatoid arthritis and various pains. to develop a method for the determination of synthetic precursors which could be remained as impurities in raw drug materials, na diclofenac pow...

The inorganic compounds, lithium polysilicate (Li 2 Si 5 O 11 ), sodium polyphosphate ((NaPO 3 ) n and phosphate monobasic (H LiPO 4 were investigated as the sole binders in Si-alloy graphite electrodes for Li cells. Surprisingly, coating quality cycling performance of anodes with these is similar to those using state art polyacrylate (LiPAA) organic binder. Graphite show good despite having po...
