Nature often provides unique and elegant solutions for solving engineering problems. For example, cactus, desert grass, Nepenthes alata have provided inspirations the design of fog-collection water-transportation devices. Here, a bioinspired hybrid fog collector consisting cactus-inspired spines featuring longitudinal ridges on surfaces peristome-inspired bottom channels decorated with curved inclined arc-pitted grooves (C-IAPGs) is developed. Experimentally, was fabricated by custom-made...
Photocatalytic conversion of methane (CH4) to ethane (C2H6) has attracted extensive attention from academia and industry. Typically, the traditional oxidative coupling CH4 (OCM) reaches a high C2H6 productivity, yet inevitable overoxidation limits target product selectivity. Although nonoxidative (NOCM) can improve selectivity, it still encounters unsatisfied activity, arising being thermodynamically unfavorable. To break activity–selectivity trade-off, we propose conceptually new mechanism...
