Two-faced characteristics and performance of materials driven by asymmetric physical or chemical properties exist in Janus hybrid which show synergistic improved for a variety applications. Here, we report facile synthesis sustainable cellulose nanofibers (CNFs) sponge with wettability strong mechanical property excellent separation efficiency oil-water emulsions. Briefly, the CNF was fabricate...

Abstract Mesoporous silica is an inorganic material that has high potential to be applied in various industrial fields, one of its applications the adsorption method. To maximize mesoporous silica, modification surface was carried out by adding amine compounds. The compound used as a modifier dimethylamine (DMA), using glycidoxypropyltrimethoxysilane (GPTMS) linking compound. column method uses...

In this essay, lipase from Burkholderia cepacia was immobilized into 3-glycidoxypropyltrimethoxysilane (GPTMS) and tetramethoxysilane (TMOS) derived sol-gels. GPTMS:TMOS molar ratio of 1:3 was found to yield the best result. The morphological characteristics were investigated based on SEM and BET analysis. Sample mean pore diameter was 39.1 nm, it had a specific surface area of 60 m2/g prior to...

Microelectrodes for hydrogen permeation measurements were fabricated by photolithography. Although the application of a positive-type photoresist coating was effective formation circle-shaped pattern with diameter several tens micrometers on an iron surface, had poor adhesion to surface and durability in H2SO4 solution. However, addition silica derived from tetraethoxysilane (TEOS) as inner lay...

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...

Nanosized zinc oxide (ZnO) particles modified with different silane coupling agents (octyltriethoxysilane (OTES), octadecyltriethoxysilane (ODTES) and (3-glycidyloxypropyl)trimethoxysilane (GPTMS)) were synthesized in basic catalysis using the sol-gel method. The structure morphology characterized by dynamic light scattering (DLS), environmental scanning electron microscopy (ESEM) Fourier trans...
