several samples of mesoporous silica were prepared via sol-gel chemistry in the presence of ctab as template with variation of stirring intensity and aging time, ratios of ctab/sio2 and nh4oh/h2o in synthesis mixture. effects of aging temperature, hydrothermal treatment and ter-butanol addition to the synthesis mixture on the textural properties of obtained samples were also studied. results of...

to improve the corrosion protection of copper metal, 0.01m concentration of 1h-1,2,4-triazole-3-thiol (tat) was incorporated into the hybrid sol-gel monolayers containing 3-glycidoxypropyltrimethoxysilane (gptms) and tetraethoxysilane (teos). it was further subjected to hydrolysis and condensation reaction to form a sol-gel matrix. the tat-doped hybrid sol-gel coating was applied over the coppe...

Light transducing phycobiliproteins are encapsulated in optically transparent sol-gel matrices. Absorption and fluorescence spectroscopies are used to characterize the effect of the sol-gel encapsulation on the conformation and aggregation states of the three major phycobiliproteins present in phycobilisomes: phycoerythrin, phycocyanin, and allophycocyanin. It is found that the effects of sol-g...

Silver nanoparticle-containing silica sol–gel coatings were synthesised using tetraethylorthosilicate (TEOS), HNO3 and AgNO3 as the main precursors and 3-(2-aminoethylamino)propyl trimethoxysilane (DIAMO) as a stabiliser. The stability and the barrier properties of the coatings were studied by means of UV/Vis spectroscopy, FTIR reflection absorption spectroscopy (IRRAS), spectroscopic Ellipsome...

We investigate the effect of the thickness of the silicon nitride (SiN x ) diffusion barrier on the structural and photocatalytic efficiency of TiO2 films obtained with different processes. We show that the structural and photocatalytic efficiency of TiO2 films produced using soft chemistry (sol-gel) and physical methods (reactive sputtering) are affected differentially by the intercalating SiN...

This work demonstrates the ability of sol-gel derived materials to support the differentiation of neuronal cells, and investigates the physiochemical interactions between the surface and extracellular matrix proteins as a mediator of the effects of surface features on differentiation. We have applied fluorescence resonance energy transfer (FRET) spectroscopy to study the conformational changes ...

Sol-gel derived GeO2-doped silica thin films (x)GeO2 :(12x)SiO2 with x 5 5 to 40 mol % were studied for heat-treatments from 500 to 1000°C. In the conventional single component sol-gel process, temperature is the process parameter that controls the porosity of the film. However, our results revealed that by varying Ge-doping, the film porosity, as determined by spectroscopic ellipsometry, can b...

Ridge and buried channel waveguides were fabricated on different substrates such as SiO2-on-Si, Si, glass wafers and Printed Circuit Boards by a sol-gel processing together with a photolithography process using photopatternable hybrid sol-gel materials. Thick sol-gel films of up to 100 microns were developed using a modified sol-gel process and ridge waveguides with vertical smooth sidewalls we...
