The rate of hydration influences many important physical properties of gypsum. Previous research examined the rate of gypsum hydration and related this to compressive strength and microstructure development using BET specific surface area analysis. The analysis of gypsum porosity in combination with BET surface area and rate of hydration remains to be done. In the present study, mesoporosity is...

A new method has been used to obtain pore size characteristics of MCM-41 catalyst supports and vanadiumsubstituted MCM-41 catalysts. The approach is based on the nonlocal density functional theory (NLDFT) model for nitrogen and argon adsorption in MCM-41, proposed recently. Samples with pore sizes varying from ca. 25 to 37 Å were prepared by hydrothermal synthesis. Two synthesis procedures empl...

Further research is needed to try utilize calcium carbonate from chicken eggshells as an adsorbent. The use of adsorbent expected minimize the amount waste generation and reduce environmental pollution. This aims Eggshell powder was activated with 0.1 M HCl solution for 48 hours, then heated in oven at 150°C 30 minutes which enlarge pores, increase surface area, volume create new pores that wil...

Despite their great potentials as biomacromolecues delivery vehicles, there are few, if any, reports on mesoporous silica nanoparticles (MSNs) simultaneously integrated with the merits of large pore size, small particle diameters and well-ordered mesostructure. Here, we designed a facile strategy for the synthesis of monodispersed MSNs using cationic surfactants (CSs) as templating agents, neut...

Various types of sodium and potassium titanate nanostructures (nanotubes, nanofibers, nanoribbons, nanwires) were synthesized and characterized by X-ray diffraction, SEM and TEM, as well BET and BJH methods. Adsorption of radiotracer 137Cs+ ions from aqueous solutions on synthesized titanate nanostructures was investigated in batch technique as a function of contact time, concentration of sodiu...

In this work, BSEA-SBA-15 was prepared for the first time, which was prepared by covalently anchoring Schiffbase compound (N,N ́-bis(salicylidene)ethylenediamine (BSEA) on SBA-15 by hydrothermal method. The structure and physicochemical properties were determined by elemental analysis, XRD, nitrogen adsorption– desorption, thermogravimetric analysis and FTIR spectroscopy, SEM, BET surface area a...
