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 ：
As a unique characteristic two-dimensional transition metal dichalcogenide, molybdenum disulfide (MoS2) has become a promising membrane material for organic solvent nanofiltration (OSN) due to its good separation performance and stability. In this work, an MoS2 tubular ceramic membrane is prepared via an in situ hydrothermal method, exhibiting quite good stability in organic solvent. The 3D nanoflower-like structure of the MoS2 layer endows the modified membrane with an excellent OSN performance. With separation of a methanol solution of Evans blue (EB), the methanol flux was 403.1 L m-2 h-1 MPa-1 and the rejection of EB was 98.1%. The adhesion structures at the surface of MoS2/Al2O3 were evaluated using density functional theory, and an interfacial distance of 3.2 Å was obtained. Considering non-bond S-O interactions in addition to van der Waals forces, the work of adhesion (0.55 J m-2) and charge transfer process between the MoS2 layer and the ceramic substrate indicate good stability. The MoS2 tubular ceramic membrane maintains separation stability after performing in organic solvents of DMF for 80 h under cross-flow. © 2021 the Partner Organisations.

Abstract ：
Cement based materials are especially vulnerable to serious temperature changes in saline land or marine environments, resulting in the degradation of structures and properties. As the main binding components in cement based materials, the investigation of the C−S−H gel structure and water molecules behaviors enabled the detail damage mechanism of cement-based material under different temperatures. In this study, C−S−H gel models were successfully constructed with the final chemical formula of (CaO)1.65(SiO2)(H2O)1.79. Systematical research works were performed on the structures and properties of both C−S−H gel and water molecules in different local environments by molecular dynamics (MD) under temperatures ranging from 100 K to 500 K. Subsequently, the time correlation function (TCF) and mean square displacement (MSD) methods were introduced to explore the dynamic properties of various chemical bonds. The volume expansion of C−S−H gel under higher temperatures resulted from stretched bond length between silicon atoms and oxygen atoms, and variation of corresponding bond angles. In addition, higher temperatures promoted the prolonged hydrogen bond length, thus reduced the number of hydrogen bond. Moreover, the polarization of water molecules was weakened gradually under higher temperatures, but water molecules’ orientation fluctuated obviously along the out of plane directions of interlayer region. Additionally, MSD results revealed that water molecules showed temperature dependent diffusion behaviors in different chemical environments. © 2020 Elsevier Ltd

Abstract ：
Molybdenum disulfide (MoS2) is widely used in membrane separation because of its outstanding chemical and structural stability. In this study, MoS2 nanosheets were in-situ grown on a tubular ceramic substrate through one-step hydrothermal synthesis with the graphene quantum dots (GQDs) incorporated in the precursor solution. The growth of the MoS2 nanosheets was inhibited due to the combination with GQDs through the Mo-O bond. Therefore, the number of transport channels in the MoS2/GQDs composite membrane were increased to improve the permeability. The results indicated that the MoS2/GQDs composite membrane have excellent permeances for both the aqueous solution and organic solvent. Moreover, the MoS2/GQDs composite membrane can be continuously operated in cross-flow filtration device for 100 h because the in-situ hydrothermal method has greatly improved the stability of membrane. The results indicated that the MoS2/GQDs composite membrane exhibits great potential in nanofiltration.

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 ：
The magnetic property of soft magnetic material is much dependent on its shape and anisotropy. In this work, the flake-like FeNi3 particles with 3D-network structure have been synthesized through hydrazine reduction at ambient condition in the presence of sodium lignosulfonate (SLS). The morphology and crystalline structure of the FeNi3 nanoparticles were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), Transmission electron microscopy (TEM) and energy dispersion spectrum (EDS). Both of the static and dynamic magnetic property of the FeNi3 particles were investigated. The results indicated that the morphology of the FeNi3 particles changed from spherical to flake shape with increasing SLS concentration or reaction time. The possible mechanism on the variation of particles morphology was proposed. The static magnetic property indicated that the flake-like FeNi3 showed a higher saturation magnetization and coercivity than that of the spherical particles. Dynamic magnetic performance showed that the flake-like FeNi3 particles also exhibited significantly higher real part (μ') and imaginary part (μ') of the complex permeability than the spherical particles, especially in the range 0.6–1.0 GHz. © 2021 The Society of Powder Technology Japan

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.
