Several composites based on an L-rich poly(lactic acid) (PLA) and mesoporous Santa Barbara Amorphous-15 (SBA-15) are prepared by their addition through two methods: solution-mixed (solvent casting) or melt-mixed (extrusion). Subsequently, films of all the materials processed compression molding. The nucleating capacity silica PLA crystallization is found to be strongly dependent protocol used f...

In this study, matrix-type transdermal patches of glibenclamide were developed using a combination hydrophilic and hydrophobic polymers for investigating the efficacy carriers. A cellulose derivative, HPMC E50, was used as matrix-forming polymer, Eudragit RS 100 polymer. The solvent casting technique employed to develop blend patch formulation chloroform methanol solvent. No drug–polymer intera...

Abstract Carbon dioxide (CO 2 ) is responsible for approximately 80% of greenhouse gases emission that the main source to global climate change causing notable environmental impacts. Poly (ethylene glycol) diacrylate (PEGDA) have polar PEG repeating units, which provide a strong affinity towards carbon molecules has been blended with 3-aminopropyltrimethoxysilane (APTMS) synthesize membrane CO ...

Coal fly ash with the addition of Al₂O₃ was recycled to produce mullite/alumina composites and the camphene-based freeze casting technique was processed to develop a controlled porous structure with improved mechanical strength. Many rod-shaped mullite crystals, formed by the mullitization of coal fly ash in the presence of enough silicate, melt. After sintering at 1300-1500 °C with the initial...

An optimal environment for glucose oxidase (GOx) in Nafion membranes is achieved using an advanced immobilization protocol based on a nonaqueous immobilization route. Exposure of glucose oxidase to water-organic mixtures with a high (85-95%) content of the organic solvent resulted in stabilization of the enzyme by a membrane-forming polyelectrolyte. Such an optimal environment leads to the high...
