The alkaline depolymerization reaction of poly(ethylene terephthalate) (PET) under quasi-solvent-free conditions was investigated. This is a new approach for recycling PET waste to its monomer building blocks: terephthalic acid and ethylene glycol. influence base particle size, temperature, rotational speed the employed laboratory kneader on yield in quasi-solid-solid depolymerized almost quant...

A resorcinol resin/water dispersion and a rubber latex are added to 1% 2,2,6,6,-tetramethylpyperidine-1-oxyl (TEMPO)-oxidized cellulose nanofibers (TEMPO-CNFs) dispersed in water, followed by oven drying at 40 °C for 20 h prepare dried TEMPO-CNF/resorcinol resin/latex (DTRL) mixture with weight ratio of 1/0.5/3. DTRL is then nitrile-butadiene (NBR) or carboxy group-containing NBR (X-NBR) sheet,...

Ketoconazole (KZ), an imidazole antifungal, was formulated into inclusion complexes via coprecipitation and kneading with β-cyclodextrin (β-CD) as a carrier in 1:1 and 1:2 drug to carrier ratios. The KZ-β-CD solid complexes were characterized by X-ray diffraction and differential scanning calorimetry (DSC). The diffraction pattern of the pure drug revealed the drug to be highly crystalline in n...
