A novel approach has been adopted for synthesizing composite polymer electrolytes with a blend of atactic poly(methyl methacrylate) (a-PMMA) and isotactic PMMA (i-PMMA) owing to their ability to form stereocomplex structures, especially double helix like structures. Nanocomposite polymeric electrolytes based on gel polymeric electrolyte (GPE) consisting of stereocomplex PMMA, propylene carbonat...

The multiplication of Plasmodium falciparum in culture, as measured by [3H]hypoxanthine incorporation, was inhibited in a dose-dependent manner by rabbit tumor necrosis serum. The regimen by which tumor necrosis serum is produced caused significant increases in the levels of triglycerides and lipid peroxides, with the latter being indicated by the level of malondialdehyde in the serum. When tum...

Using differential scanning calorimetry, we show that the addition of solute(s) to emulsified water lowers the freezing temperature to <231 K, the homogeneous nucleation temperature of pure bulk water, or even completely suppresses freezing. In the latter case, freezing upon warming occurs above T(X) ≈ 150 K and leads to a phase separation into pure ice and a freeze-concentrated solution (FCS) ...

Thermal wetting can simply, selectively and reversibly join patchy particles into clusters (2D and 3D) and also colloidal crystals over the narrow temperature range of 1-2 °C. This is demonstrated with Janus particles (gold half-coated silica spheres) immersed in a binary mixture of water/2,6-lutidine, such that the relative strength of gold-gold bonding through hydrophobic interaction and sili...

Stripping is one of the major distresses within asphalt concrete pavements caused due to penetration water interface asphalt-aggregate matrix. In this work, grade cement (40-50) was mixed with variable percentages three types additives (fly ash, fumed silica, and phosphogypsum) obtained an modified resist effect stripping phenomena .The specimens have been tested for physical properties accordi...
