Equations were obtained from response surface models to show how the ultimate tensile strength (UTS) and percent elongation at break (%E) of solution-cast films vary with relative amounts of starch. poly(vinyl alcohol) (PVA). poly(ethylene-co-acrylic acid) (EAA) and glycerol in the formulation. Equations found from the response surface methodology were used to optimize the relative amounts of t...

Rodlike two-component mixed crystals composed of 1-(5-methyl-2-phenyl-4-thiazolyl)-2-(5-methyl-2-p-tolyl-4-thiazolyl)perfluorocyclopentene (1a) and 1,2-bis(5-methyl-2-p-tolyl-4-thiazolyl)perfluoroc...

Graphene oxide/poly(vinyl alcohol) (GO/PVA) composite hydrogel was prepared and utilized for selective drug release at physiological pH.

Novel nanocomposite films based on amylose (AM) and Fe3+-montmorillonite (Fe3+–MMT) in the matrix of poly (vinyl pyrrolidone) (PVP) were fabricated by using a solution casting method. The X-Ray diffractional analysis indicated that an ion-exchange process occurred between Fe3+–MMT and PVP. Thermogravimetrical analysis (TGA), differential termogravivetrical analy...

Organic solvents are widely used as reaction media and/or for the separation and purification of synthetic products in chemical pharmaceutical industries [...]

We develop coarse-grained force fields for poly (vinyl alcohol) and poly (acrylic acid) oligomers. In both cases, one monomer is mapped onto a coarsegrained bead. The new force fields are designed to match structural properties such as radial distribution functions of various kinds derived by atomistic simulations of these polymers. The mapping is therefore constructed in a way to take into acc...

throughout the present, caseinate based edible films containing extracts of pomegranate peel were prepared in 3 levels of ×1, ×1.5 and ×2 (mic) and the physicomechanical, thermal, antimicrobial, and barrier properties of the films studied. to assess the microstructure changes resulting from the addition of the antimicrobial extracts, sem images were prepared from the surface and cross-section o...
