Abstract ：
Molybdenum disulfide-based membranes have received wide attention for their excellent performance in chemical separation field. Yet, manipulating the structure of MoS2 membranes still remains an unprecedented challenge. In this work, the tubular MoS2 ceramic membranes were prepared by in-situ hydrothermal method using aqueous solution of thiourea and ammonium molybdate as precursor solution. The structure and morphology of the membranes were manipulated by introducing different alcohols into the precursor solution. The results indicated that the presence of alcohols drove the transformation of MoS2 morphology from nano sheets to spherical aggregates. As the molecular weight of the alcohols decreased, more small-sized molybdenum disulfide spheres were formed on the tubular ceramic substrate, which resulted in the formation of a great number of large transportation channels and promotion of surface area, and thereby improved the permeability of the membrane. Moreover, the addition of different alcohols enhanced the negative charge of the membrane surface, which ensured an effective rejection while enhancing the membrane permeability. The results demonstrate that the membranes prepared in a water-ethanol mixed solvent possess an excellent permeability for water (33.2 L/(m(2) h bar)) and methanol (52.2 L/(m(2) h bar)), with a rejection of more than 97% for Eriochrome black T, and an excellent pressure resistance as well as long-term running stability under cross-flow filtration. In addition, such membrane exhibited a below 30% rejection for salts, which can be utilized for dye desalination.

Abstract ：
In order to obtain low-cost and excellent adsorption materials, this paper used calcium acetate and water glass as raw materials to synthesis hydrated calcium silicate gel by precipitation method. The performance and structure of hydrated calcium silicate gel were systematically studied by X-ray photoelectron spectroscopy, fourier transform infrared spectroscopy, specific surface area analyzer and scanning electron microscope. Studies have shown that, non-crystal hydrated calcium silicate gel (CSH) were successfully prepared, and the removal rate of lead ion using CSH reached more than 90%. The adsorption process is consistent with the pseudo-second-order kinetic model and Langmuir adsorption isotherm model, and the limit adsorption capacity reaches 263.17 mg·g-1. The acid treatment experiment proved that the adsorption capacity of lead ion using CSH was satisfactory, and the adsorption rate remained at >60% after 5 cycles. The research may provide a low-cost, high-efficiency and high stability adsorbent.

Abstract ：
Organic solvent nanofiltration is a promising separation technology for removing solute from an organic medium. However, the fabrication of organic solvent nanofiltration membranes with stable separation performance is still a challenge. Herein, a hydrophobic polyelectrolyte multilayer membrane was prepared through a layer-by-layer self-assembly and counterion exchange method. Poly(diallyl dimethyl ammonium chloride) (PDDA)/polyacrylic acid (PAA) multilayer was self-assembled on the surface of the hydrolyzed polyacrylonitrile substrate through electrostatic interaction. Simultaneously, calcium silicate hydrate (CSH) nanoparticles were in situ grown during the multilayer formation process due to the incorporation of precursor in polyelectrolyte solutions. Therefore, the surface roughness of the membrane was enhanced and the anti-swelling property of the polyelectrolyte multilayer was also improved. The hydrophilic [(PDDA/PAA-CSH)2.5]+Cl− membrane was then converted to the hydrophobic membrane through the counterion exchange between Cl− and perfluorooctanate (PFO−) ions. The obtained [(PDDA/PAA-CSH)2.5]+PFO− membrane has a water contact angle of 118°, which can be used to separate dyes from ethanol. Both the separation performance and stability of the polyelectrolyte multilayer membrane were improved through the in situ growth of calcium silicate hydrate nanoparticles and counterion exchange by perfluorooctanate ions. Therefore, this strategy may open a new avenue to prepare organic solvent nanofiltration membranes. © 2020 Elsevier B.V.

Abstract ：
Isophorone diisocyanate (IPDI) was encapsulated successfully within double-layered shells, and final microcapsules showed outstanding self-healing functions in cement paste. The well-dispersed microcapsules had a diameter of 347.0 +/- 103.4 mu m, shell thickness of 3.1 +/- 0.4 mu m, and core fraction around 74.8% +/- 1.9% by weight. The diameters of microcapsules were adjustable by varying agitation rates. The beginning weight-loss temperature of microcapsules was 200 degrees C, implying good thermal stability. The final microcapsules affected slightly the workability and setting time of fresh self-healing cement paste. Although the mechanical strength of hardened self-healing cement paste was decreased with the increase of microcapsule concentrations, the open porosity was improved obviously from 33.5% (control samples) to 31.8% when 5.0% by weight of microcapsules was introduced. The interfaces of microcapsules were compatible enough with cement paste without obvious delamination. Especially, the self-healing cement paste showed outstanding self-healing functions in open air when 10.0% by weight of microcapsules was introduced. (C) 2021 American Society of Civil Engineers.
