H2 sensors based on WO3 thin films activated by platinum nanoparticles synthesized by electroless process
Platinum (Pt) nanoparticles were successfully synthesized on tungsten oxide (WO3) thin films by electroless process without any further post-treatment. The prepared Pt nanoparticles were characterized by X-ray diffraction, X-ray photoelectron spectroscopy and field-emission scanning electron microscopy. Gas sensors based on the Pt–WO3 films were found to provide repeatable and significant respons...

181. Morphology and Photocatalytic Property of Hierarchical Polyimide/ZnO Fibers Prepared via a Direct Ion-exchange Process.
A simple and efficient method has been developed for preparing hierarchical nanostructures of polyimide (PI)/ZnO fibers by combining electrospinning and direct ion-exchange process. Poly(amic acid) (PAA) nanofibers are first prepared by electrospinning, and then, the electrospun PAA fibers are immersed into ZnCl2 solution. After a subsequent thermal treatment, imidization of PAA and formation of Z...

122. Can spherulitic growth rate accelerate before impingement for a semicrystalline polymer during the isothermal crystallization process?
Isothermal crystallization processes in the temperature range from 110 to 140 °C were studied by using polarizing optical microscopy (POM) for poly(L-lactide) (PLLA) film samples with and without confinement conditions. The PLLA film samples were prepared by melt pressing between two cover glasses to provide the surface confinements and by removing the top cover glasses or by solution cas...

Preparation of Mesoporous Submicrometer Silica Capsules via an Interfacial Sol-Gel Process in Inverse Miniemulsion
Mesoporous silica capsules with submicrometer sizes were successfully prepared via the interfacial hydrolysis and condensation reactions of tetraethoxysilane (TEOS) in inverse miniemulsion by using hydrophilic liquid droplets as template. The inverse miniemulsions containing pH-controlled hydrophilic droplets were first prepared via sonication by using poly(ethylene-co-butylene)-b-poly(ethyl...

A sol-gel process for fabrication of NiO/NiCo2O4/Co3O4 composite with improved electrochemical behavior for electrochemical capacitors
Transition metal oxides possess multiple oxidation states that enable rich redox reactions for pseudo capacitanc. They have been investigated as promising electrode materials to achieve high energy density. In this study, NiO/NiCo2O4/Co3O4 composite with high specific surface and mesoporous structure is fabricated by a sol−gel process then calcined at 250 °C. Benefits from the improved e...

Facile preparation of super-hydrophobic and super-oleophilic silica film on stainless steel mesh via sol-gel process
A super-hydrophobic and super-oleophilic silica film on stainless steel mesh was obtained by simple sol-gel method using tetraethoxysilane (TEOS) and methyltriethoxysilane (MTES) as precursors. The super-hydrophobic and super-oleophilic properties were achieved owing to the hierarchical structure of the silica film with methyl groups terminated domains constructed on the mesh. The effects of the p...

Stretching-Controlled Micromolding Process with Etched Metal Surfaces as Templates Towards Mass-Producing Superhydrophobic Polymer Films
A novel technique is described that uses stretching-controlled thermal micromolding with etched metal surfaces as templates for the mass-production of superhydrophobic polymer films. First, the metal surface is etched and then used as a template to thermally replica-mold the polymer (e.g., polyethylene). The resulting film surfaces exhibited stable superhydrophobicity with water contact angles >...
