A green one-pot approach is used to synthesize surface morphology controlled hollow silica spheres in aqueous solution under ambient conditions. Using cationic polystyrene particles as a template and aminopropyltriethoxysilane (APTES) as a structural directing agent, the surface roughness and wall thickness could be easily controlled by varying the concentration of tetraethoxysilane (TEOS). Smo...
Recently, quantum dots have been used as molecular probes substituting for conventional organic fluorophores. Quantum dots are stable against photobleaching and have more controllable emission bands, broader absorption spectra, and higher quantum yields. In this study, an array of ZnS-coated CdSe quantum dots on a slide glass has been prepared by photolithographic method. The array pattern was ...
We present a technique for hysteresis suppression in single-wall nanotube field effect transistors (SWNT-FETs) using chemical functionalization. We selectively modify the electrode surfaces and the device channel area with self-assembled monolayers (SAMs) of octanethiol and aminopropyltriethoxysilane (APTES), respectively. These can efficiently prevent surface adsorption of water molecules. We ...

The development of selective and cheap metal oxide gas sensor at ambient temperature is still a challenging idea. In this study, SnO2 surface functionalization was performed in order to obtain sensitive and selective gas sensor operated at ambient temperature. 3-aminopropyltriethoxysilane (APTES) was used as an intermediate step, followed by functionalization with molecules having acyl chloride...
• Moisture increases CO 2 adsorption in the material modified with a tertiary amine. 13 ssNMR and DFT methods provided molecular insights into mechanisms. Selectivity remarkably amine moisture. DFT/cluster calculations confirmed water effect on adsorption. The of minor amounts CH 4 primary secondary amine-functionalised mesoporous silicas (APTES@SBA-15 DEAPTES@SBA15, respectively) was studied c...
Abstract Soybean hulls (SBHs) are one of the main by-products soybean crushing, usually destined for animal feeding or to become a putrescible waste. In this work, we upgraded SBHs materials with antimicrobial properties. After extraction peroxidase from SBHs, an enzyme applicable in different technological sectors and naturally present hulls, exhausted biomass was subjected acid–base treatment...
