Revision of the opinion on Silica, Hydrated Silica, and Silica Surface Modified with Alkyl Silylates (nano form)

Self-assembly of colloidal particles into colloidal films has many actual and potential applications. While various strategies have been developed to direct the assembly of colloidal particles, fabrication of crack-free and transferrable colloidal film with controllable crystal structures still remains a major challenge. Here we show a centrifugation-assisted assembly of colloidal silica sphere...

In the emerging issue of increased multi-resistant properties in foodborne pathogens, silver nano particles are being used increasingly as antimicrobial agents. Thus, the minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) of Nano Colloidal Silver towards food-borne pathogens such as Escherichia coli O157:H7, Listeria monocytogenes, Salmonella enterica Serovar Ty...

to resolve handling problem of nanoparticles, due to their small size, a new methodology of electro-spraying and freeze-drying was developed for colloidal nanoparticles of silica and titania to transform them to solid macro-scale nanoparticle assemblies.  the assemblies were then redispersed in an aqueous system to investigate the effect of formulation of original solutions and the process para...

the effects of adding nano-silica particles on the compressive strength and water permeability of concrete and its comparison with that of micro-silica were investigated in this work. the effect of combination of nano- silica and micro-silica were also studied in this work, which resulted in an increase in compressive strength of concrete in comparison with other concrete specimens tested in th...

The synthesis of bulk imprinted silica using colloidal gold as a functional template is demonstrated. The imprinting approach relies on the isolation of colloidal gold in gold@silica nanoparticles synthesized via a 3-aminopropyltrimethoxysilane (APS) route. Gold@silica nanoparticles are then condensed within a silica framework for the synthesis of a composite gold-silica material containing ~30...
