Synthesis of macro-mesoporous Pt/alumina catalyst to enhance catalytic activity of hydrogen oxidation
Macro-mesoporous Pt/alumina catalysts were synthesized by the sol-gel process with the assistance of a PS colloidal crystal template to improve the catalytic activity of hydrogen oxidation. Macropores in catal...

A Novel Method for Fine Patterning by Piezoelectrically Induced Pressure Adjustment of Inkjet Printing
In this paper, a method is proposed for fine line pattern formation on polyimide films by drop-on-demand inkjet printing without the need to reduce the nozzle size. The rapid change in the shape of a piezoelec...

The Ferromagnetic Conditions for Ni3Al and Ni3Ga
We investigated the difference between Ni3Al and Ni3Ga in terms of their ferromagnetism. Using the analogy of our group model for high transition temperature superconductivity (HTSC), we determined the ferromagne...

Synthesis and thermoelectric characterization of bulk-type tellurium nanowire/polymer nanocomposites
A simple method to fabricate three-dimensionally (3-D) aligned thermoelectric nanowires attached polymer particle was demonstrated by combination of solution casting of thermoelectric nanostructures (e.g., tellur...
