Superhydrophobic alkylsilane functionalized cellulose beads for efficient oil/water separation

Recent advances in nano-fertilizers: synthesis, crop yield impact, and economic analysis

“…74–76 This process is usually uncontrolled due to the reaction kinetics, resulting in a wide range of molecule sizes and uncontrolled particle morphology, with solids often agglomerating. 61,77–79 To produce nanoparticles with a narrow size distribution, high supersaturation levels, uniform spatial concentration distribution within a reactor, and uniform growth time for all particles are necessary. 80…”

Novel chemically reduced cobalt-doped g-C3N4 (CoCN-x) as a highly heterogeneous catalyst for the super-degradation of organic dyes via peroxymonosulfate activation

“…Hence, the absorption peaks occurring at 2900-3400 cm À1 were associated with vibrations of free amino groups -NH that resulted from incomplete polymerization, as well as adsorbed hydroxyl species (-OH). [55][56][57] Meanwhile, the peaks at 1200-1650 cm À1 and the characteristic peak at 809 cm À1 correspond to the typical stretching modes of C-N heterocyclic rings and the vibration absorption of the triazine units, respectively. 43 The FTIR analyses of CoCN-x samples showed that the spectra of g-C 3 N 4 remained unchanged after co-doping, except for a decrease in the peak intensity, as well as shifts in the peak positions.…”

Superhydrophobic Bud Protrusion-Polypropylene Fiber Membrane with Ultrahigh Flux for Oil–Water Separation

“…Superhydrophobic membranes coated on the substrate of cellulose filter paper, cotton cloth, and other covalent organic frameworks have shown efficient separation of oil–water mixtures and attracted more attention in the field of oil–water separation due to the unique wettability of their surfaces. He et al .…”

“…7 To treat large quantity of oily wastewater, it is urgent to explore membrane materials possessing high flux, excellent rejection, and organic solvent resistance. 8−10 Superhydrophobic membranes coated on the substrate of cellulose filter paper, 11 cotton cloth, 12 and other covalent organic frameworks 13 have shown efficient separation of oil− water mixtures and attracted more attention in the field of oil− water separation due to the unique wettability of their surfaces. He et al 14 successfully prepared a modified sponge (PCP@ MS, porosity >99.5%) by embedding Co-HHTP photothermal material and coating melamine sponge (MS) with low surface energy polydimethylsiloxane (PDMS).…”
