this paper presents theoretical and numerical state-of-the-art information in the field of hygro-thermo-mechanical deformation simulation in structural concrete. the aspects discussed include coupled hygro-thermo-mechanical performance of porous materials including concrete, multi-scale simulation of concrete properties especially the volumetric and structural deformation performance, and the m...

The porous structure within the cathode material influences capacity and operating performance of LiS batteries. Here, we prepared special carbon using sodium chloride as template/temporary space-holders to design mixture micro−/meso−/macroporous with large surface area through a facile water bath freeze-drying process. Such modification led high sulfur content 73.2% remarkable initial 1378 mAh...

High activity of a catalyst and its thermal stability over lifetime are essential for catalytic applications, including gas sensors. Highly porous materials attractive to support metal catalysts because they can carry large quantity well-dispersed nanoparticles, which well-accessible reactants. The present work investigates the long-term mesoporous Co3O4-supported Au–Pd (Au–Pd@meso-Co3O4), with...

We describe the synthesis and characterization of a new N-methylpyrrolidine-fused meso-tetracarboxyphenylchlorin with highly emissive features. The synthetic approach to obtain fluorescent chlorin involves microwave-assisted meso-tetrakis (4-methoxycarbonylphenyl)porphyrin, followed by 1,3-dipolar cycloaddition reaction this porphyrin azomethine ylide and, finally, ester hydrolysis under basic ...

A supramolecular chiral host consisting of N-(2-naphthoyl)-L-aspartic acid (L-1) and meso-1,2-diphenylethylenediamine (2) is effective in enantioseparation of 1-arylethanols (up to 96% ee with 100% inclusion ratio). Here we report three different methods to prepare the inclusion crystals and discuss the chiral recognition mechanism on the basis of X-ray crystallography results.

Hydrophobic silica titanium nanoparticles (STNPs) were successfully synthesized by the sol-gel process using liquid modification. Fourier transform infrared (FTIR) and X-ray fluorescence (XRF) studies were demonstrated the attachment of titanium on the silica surface. Titanium content enhanced the agglomeration of particles as shown in topography results. The N2 adsorption-desorption followed T...

In this study, bimodal meso-porous silica (UVM-7) synthesized and fabricated amino silane modified supports were characterized by powder X-ray diffraction (XRD), N2 adsorption/desorption, transmission electron microscope (TEM), elemental analysis and titration. Capacity of CO2 capture on modified bimodal pore structure silica at 70°C was calculated using breakthrough curves; and it was found th...
