Fog harvesting is considered a promising freshwater collection strategy for overcoming water scarcity, because of its environmental friendliness and strong sustainability. Typically, fogging occurs briefly at night in the early morning most arid semiarid regions. However, studies on from short-term fog are scarce. Herein, we developed patterned surface with highly hydrophilic interconnected microchannels superhydrophobic to improve droplet convergence driven by Young–Laplace pressure...

Hybrid hierarchically porous silica adsorbents were simply fabricated by the sol–gel method and modified with thiol or sulfonic groups. These materials pores on both micrometre nanometre scales exhibit a satisfactorily adsorptive property to various pollutants in water, including heavy metal ions (Hg2+, Cd2+, Pb2+, Cu2+, Ag+ CrO42−) organic compounds (dyes, biogenic amines, pesticides amino acids). The functionalized micro-foam (SH-HSM), which has low content (0.66 mmol g−1), shows...
