Toward a facile synthesis of spherical sub-micron mesoporous silica: Effect of surfactant concentration

In this paper, a facile method for preparing sub-micron spherical mesoporous silica by the sol-gel process and cationic surfactant cetyltrimethylammonium bromide (CTAB) as a soft template was reported. Moreover, the effect of surfactant concentration on the specific surface area and the total pore volume was investigated. The specific surface area, pore characteristic, morphology, chemical comp...

Sol-Gel Synthesis, Characterization and Optical Properties of Bi 3+ - Doped CdO Sub-Micron Size Materials

Highly crystalline Bi3+-doped cadmium oxide (CdO) sub-micron structures were synthesized by calcination the obtained precursor from a sol-gel reaction. The reaction was carried out with cadmium nitrate (Cd(NO3)2.4H2O), bismuth nitrate (Bi(NO3)3.5H2O) and ethylene glycol (C2H6O2) reactan...

Effect of nano and micron WO3 on microstructure and electrical properties of lead free potassium sodium niobate piezoceramics

Lead free potassium sodium niobate (KNN) piezoceramics were synthesized via conventional solid state sintering route. Nano and micron WO3 were separately added to KNN through ball-milling. Dielectric and piezoelectric properties of samples sintered in the temperature range of 1110°-1145°C were measured by precision LCR-meter and APC d33-meter devices. The results revealed that micron WO3 partic...

Fused-core particles: a practical alternative to sub-2 micron particles.

The benefits of sub-2 micron particle size columns have been widely researched and published. The use of these columns on ultrahigh-pressure liquid chromatography (UHPLC) instrumentation may lead to increased efficiencies and higher throughput. However, these instruments may not be readily available to the pharmaceutical chemist. Within the past year, a practical alternative has been introduced...
