Quantum energy levels of hydrogen adsorbed on nanoporous carbons: an intrinsic probe for pore structure, and improving Monte Carlo simulations of adsorption [abstract]
(2009)
Hydrogen is the lightest molecule in nature, making both rotational and translational degrees of freedom eminently quantum mechanical (especially at low temperatures). For isolated molecules the first excited (degenerate) ...
Structural and energetic factors in designing a perfect nano-porous sorbent for hydrogen storage [abstract]
(2009)
Carbons are one of several promising groups of materials for hydrogen storage by adsorption. However, the heat of hydrogen physisorption in such materials is low, in the range of about 4-8 kJ/mol which limits the total ...
Output Power Enhancement of GaN Light Emitting Diodes with p-type ZnO Hole Injection Layer [abstract]
(2009)
The efficiency for LED lamps designed for replacement of incandescent bulbs for use in general home and commercial illumination has been steadily increasing, with an accompanying decrease cost in $/lumen. These LED lamps ...
Characterizations of Semiconductor Photodetectors for UV Detection [abstract]
(2009)
Wide band-gap semiconductors have shown great potential in UV light detection as modern optoelectronic devices. During the past decade, wide-bandgap GaN and AlGaN photodetectors have been developed and their UV characterizations ...
