Abstract Thermosetting resins were formulated by mixing solid epoxy components, hardener and accelerator at elevated temperature. These mixtures ground into uncured, resin powders dispensed onto carbon fibres using a powder printer prior to vacuum curing. Using accelerators reduced curing time from 8 h 16 min. Manufactured cross-ply fibre laminates (0°/90°/0°) had comparable mechanical properti...
Combining several materials (“phases”) into a composite material permits creation of new materials with tunable overall response, e.g., elastic properties, which can be related to the elastic moduli, arrangement, and concentrations of the composite’s phases. A recent advance predicts use of one phase having correctly tuned non-positive-definite elastic moduli (i.e., negative stiffness) in a two...
Extended Abstract Introduction and Objective: To overcome the problems caused by animal feed shortages, efforts are made to increase the availability of nutrients and their digestibility, such as improving the nutritional value of forage plants through biological processing. Schizophyllum commune is an edible fungus of the basidiomycete’s family that has been used for biological processing of ...
The solid–liquid equilibrium (SLE) behavior and liquid–liquid extraction (LLX) abilities of deep eutectic solvents (DESs) containing (a) thymol L-menthol, (b) trioctylphosphine oxide (TOPO) L-menthol were evaluated. distribution coefficients (KD) determined for the solutes relevant two biorefinery cases, including formic acid, levulinic furfural, acetic propionic butyric L-lactic acid. Overall,...
