Subsequent solvent exchange followed by vacuum drying yielded polymeric foams with different morphologies.
The Eucalyptus nanofibril-based films, made by free drying, yield lower densities than the corresponding P. radiata nanofibril-based films.
Polymer P2 was synthesized using the same method as P1, giving a white powder after drying (yield = 85%%).
Spray drying yield, particle size, size distribution, moisture content and protein stability were evaluated as the responses.
The solid was collected, and extracted with methanol by Soxhlet apparatus for 24 h, brown solid was obtained after drying (yield ~95%).
The dissolved polymer was then precipitated in 100 ml of methanol and washed again with the same, giving a white powder after drying (yield = 81%%).
The aqueous extract was then concentrated by heating at 60°C and was later subjected to freeze- drying (yield 7.36% and 11.61% w/w, dry weight basis for leaf) and was stored in a container until further use.
The analysis of sludge sampled before and after different unit operation steps (i.e., anaerobic digestion, sludge heat treatment, and sludge drying) yielded insights into the extent and location of TCC and TCS transformation.
Surface coating, any mixture of film-forming materials plus pigments, solvents, and other additives, which, when applied to a surface and cured or dried, yields a thin film that is functional and often decorative.
The effect of the studied parameters on the spray dried yield, loading efficiency and in vitro release were thoroughly investigated.
