Ordered mesoporous Cd(x)Zn(1-x)S ternary compound semiconductors were prepared with a simple nano-casting method using 3-D cubic Ia3d meso-structured silica, KIT-6, as a hard-template with the easily available precursors of 3CdSO4 x 8H2O and ZnSO4 x 7H2O. Thermal reduction of impregnated precursors resulted in the crystalline networks within the mesopore of the silica template, then the ordered...

A previous paper (Marks, 1957) describes work done on a number of substances to ascertain their protective effect on phagocytic cells in tissue culture against injury by silica dust. The most potent of those investigated was 48-80, a drug used in experimental pharmacology to release histamine from mast cells. In the present paper, several drugs related to compound 48-80 have been examined for t...

We have prepared thermoresponsive chromatographic matrices by introducing poly(N-isopropylacrylamide) chains onto silica beads for separation of bioactive compound in aqueous media [1]. This system is highly useful to control function and properties of the stationary phase for high performance liquid chromatography (HPLC) by only change in column temperature, and has advantages in maintaining b...

The idea of smart corrosion inhibition is basis on either inhibitor consumption where it is needed or reducing harmful matrix interaction with it. In addition, applying corrosion inhibitor in a coating causes many problems such as loss of inhibition capability, coating degradation, or both. A useful technique to overcome this problem is applying of inert host systems of nanometer dimensions as ...

In this contribution, an effective and soft method for removal of template from nanochannels of mesoporous silica (MCM-41) is proposed. This method is based on chemically-modified solvent extraction which enhanced by means of an auxiliary organic compound, i.e. benzene sulfonamide. Template removal was performed in soft condition, i.e. in the presence of diluted sulfuric acid and at ambient tem...

essential oil of the orange peel which was extracted by hydrodistillation method showed 50 different mono- and sesquiterpenes on gc-ms analysis, in which limonene had the highest percentage (92.4%). due to various important uses of the compound, a method was developed for isolation and purification of limonene. in this method, for extra purification, a fractional distillation on vigreux column ...

An efficient use of plasticizers in rubber compounds requires an understanding their miscibility behavior. Besides the chemical properties both and plasticizer, rigidity plasticizer plays important role for miscibility. The is investigated here using glass transition measured by differential scanning calorimetry broadband dielectric spectroscopy (BDS). Additionally, interfacial relaxation phase...

Calcium carbonate is the most abundant biomineral and a compound of great industrial importance. Its precipitation from solution has been studied extensively and was often shown to proceed via distinct intermediate phases, which undergo sequential transformations before eventually yielding the stable crystalline polymorph, calcite. In the present work, we have investigated the crystallisation o...
