Achieving stable operation of photoanodes used as components of solar water splitting devices is critical to realizing the promise of this renewable energy technology. It is shown that p-type transparent conducting oxides (p-TCOs) can function both as a selective hole contact and corrosion protection layer for photoanodes used in light-driven water(More)
The plastic material known as cyclic olefin copolymer (COC) is a useful substrate material for fabricating microfluidic devices due to its low cost, ease of fabrication, excellent optical properties, and resistance to many solvents. However, the hydrophobicity of native COC limits its use in bioanalytical applications. To increase surface hydrophilicity and(More)
Stable platinum nanoparticles were prepared by the self assembly of acetylene derivatives (1-alkynes, 4-ethylphenylacetylene, and 4-tert-butylphenylacetylene) onto bare Pt colloid surfaces. Transmission electron microscopic measurements showed that the nanoparticles exhibited an average core size of 2.85 ± 0.62 nm. FTIR study showed that with the acetylene(More)
Polymeric materials possess many attractive properties such as high toughness and recyclability. Some possess excellent biocompatibility, are biodegradable, and can provide various biofunctionalities. Proper combination of functional polymers and biomolecules can offer tailored properties for various biomedical applications. This overview article covers(More)
The severe adhesion between silicon and glass has limited its application as mold material in precision glass molding. In this paper, a novel coating approach to create non-stick silicon mold for glass molding was introduced by using carbide-bonded graphene, a two dimensional material with a patterned atomic structure. A graphene coated silicon mold was(More)
