Antibacterial activity of ZnO nanoparticle suspensions on a broad spectrum of microorganisms.

Nanoparticle metal oxides represent a new class of important materials that are increasingly being developed for use in research and health-related applications. Highly ionic metal oxides are interesting not only for their wide variety of physical and chemical properties but also for their antibacterial activity. Although the in vitro antibacterial activity and efficacy of regular zinc oxides have been investigated, little is known about the antibacterial activity of nanoparticles of ZnO.

Rapid and facile synthesis of siliceous MCM-48 mesoporous materials.

A rapid and facile synthesis of cubic MCM-48 mesoporous material based on the modification of Stöber synthesis in as little time as 30 minutes at room temperature is reported in this communication.

Synthesis of mesoporous aluminophosphate (AlPO) and investigation of zirconium incorporation into mesoporous AlPOs.

Mesoporous aluminophosphate materials with variable amounts of zirconium have been synthesized at room temperature using a nonionic surfactant tri-block copolymer (PEO(20)PPO(70)PEO(20)) as the structure-directing agent. Powder X-ray diffraction of as-synthesized and calcined AlPO and ZrAlPO mesoporous materials shows a single broad peak near 2theta = 2.5 degrees, indicative of the average pore-pore correlation distance.

Amphiphilic templating of magnesium hydroxide.

The synthesis of lamellar mesostructured Mg(OH)2 was achieved through a surfactant templating route. Amphiphilic compounds with different anionic headgroups (phosphate, sulfate, sulfonate, and carboxylate) were used as surfactants. Control of d spacing was achieved through the use of different alkyl carboxylate amphiphiles.
