Amomum villosum Lour. (A. villosum) is widely utilized in culinary and medicinal contexts due to its rich diversity of bioactive compounds. In this study, an ultrasonic-assisted extraction (UAE) method using a natural deep eutectic solvent (NaDES) was employed extract flavonoids from A. villosum. The NaDES composed betaine glycerol (Bet-Gly) exhibited effective performance as solvent, evidenced by high efficiency. Optimal conditions (water content: 30 %, solid-liquid ratio: 1:20 g/mL,...
Previous studies used to take the regular configuration as element of cellular structures, then carry out geometric optimization on initial structures. Nowadays, more and bionic metamaterial have been studied for their unique properties, such honeycomb tubular nested structure, sinusoidal honeycomb, butterfly bamboo beetle forewing thin-walled Here, we report a novel gardenia-shaped (GSH) by observing gardenia from nature. Two valuable mechanical properties within GSH were explored in this...
Theories of moiré deflectometry are presented based on scalar diffraction theory. It is shown that the effect not a pure geometric phenomenon but actually result multishearing interference. By performing zeroth-order or first-order filtering, field in plane observation seen to be double- triple-shearing interference, respectively. With intensity distribution proved strict cosinusoidal distribution, and effect, which depends distance between two gratings, affects just phase shift fringes....

Ultrafine copper powders were prepared by the air-jet milling of oxide (CuO) and a subsequent hydrogen (H2) reduction. After milling, particle size grain CuO decreased, while specific surface area structural microstrain increased, thereby improving reaction activity. In pure H2 atmosphere, process reduction was conducted in one step, followed pseudo-first-order kinetics model. The smaller after exhibited higher rates lower activation energies compared with those without milling. Based on...
