Microencapsulation has become a hot topic in chemical research. Technology mainly used for control release and protection purposes. The sol-gel micro encapsulation approach for fragrance and aroma in porous silica-based materials leads to sustainable odorant and flavored materials with novel and unique beneficial properties. Sol-gel encapsulation of silica based micro particles considered econo...

Nanocrystalline complex oxides have been synthesized by combination of sol–gel auto combustion and ultrasonic irradiation techniques using copper nitrate, zinc nitrate as metallic nitrates and glycine, urea and thiourea as fuels. Sol-gel combustion (combination of the chemical sol–gel process and the combustion process) as a proper synthesized technique is used to synthesize ZnO/CuO nanocomposi...

Thin films of organically modified silica (ORMOSILS) produced by a sol-gel method were imprinted with whole cells of a variety of microorganisms in order to develop an easy and specific probe to concentrate and specifically identify these microorganisms in liquids (e.g., water). Microorganisms with various morphology and outer surface components were imprinted into thin sol-gel films. Adsorptio...

objective(s): cao–mgo–sio2 system bioceramics possess good characteristics for hard tissue engineering applications. the aim of the study was to synthesize the nano powder by using a sol-gel method and evaluate of bioactivity in the cells culture. methods: to characterize of powder x-ray diffraction (xrd), transmission electron microscopy (tem) and to evaluate the bioactivity sample cell seedin...

the synthesis of titania via sol-gel method has been widely studied. in the present work, titania was deposited onto a titanium substrate via sol-gel method. different processing parameters such as the repetition number of dipping/heat treatment process and dipping time have been studied to obtain the homogenous titania coating. phase and microstructural evaluation of the powder and coating sam...

Here, we describe the development of a bi-enzymatic biosensor that simplifies the sample pretreatment steps for insecticide detection, and opens the way for a highly sensitive detection of phosphorothionates in food. These compounds evolve their inhibitory activity towards acetylcholinesterases (AChEs) only after oxidation, which is performed in vivo by P450 monooxygenases. Consequently, phosph...

An octadecyl-functionalized solid-phase microextraction (SPME) fiber was prepared by sol-gel technology with an anodized Ti wire as the substrate and dimethyloctadecyl[3-(trimethoxysilyl)propyl]ammonium chloride (C(18)-TMS) and tetraethoxysilane (TEOS) as sol-gel precursors. The anodized Ti wire has high mechanical strength and has numerous titanol groups on its surface for sol-gel reactions, c...

It is well known that in recent years magnetic materials have received increased attention due to their properties. For this reason a significant number of patents that were published during the last decade are oriented towards synthesis and study of such materials. The aim of this work is to create and study ferrite nanocrystalline materials with spinel structure, using sol-gel technology with...

A biofilm is a group of microorganisms that attach and grow on a solid surface. Biofilms are common in nature. They can cause clogs and corrode pipes, cause infections when formed on medical implants, and cost billions of dollars in damages, so it is desirable to prevent their growth. This work explores the ability of electrospun titanium dioxide to inhibit the growth of biofilms of pseudomonas...
