Porous Gallium Nitride Generated by Electroless Etching: Morphology, Optical Properties, and Sensing Applications
… several possible applications for porous GaN have been explored. Currently, because there is not a route for the growth of bulk GaN, GaN films must be grown heteroepitaxially. Substrates for GaN growth are not ideal, and introduce strain and defects. Porous GaN has been studied as …

Bismuth nanowire and antidot array studies motivated by thermoelectricity
Porous anodic alumina (PAA) films were utilized to template the fabrication of nanostructures of bismuth, antimony and bismuth-antimony alloys. The cylindrical template pores were used to synthesize nanowires by electrochemical methods. The porous surface of the template was used as a substrate for …

Doped tungsten oxide nanocrystals for next generation electrochromic windows
… electrochromic windows compared to bulk thin films. The difference lies in intrinsic WO₃ [subscript -x] NC properties of shape and crystalline anisotropy with localized surface plasmon resonance absorption in the shorter wavelength near-infrared range, which can directly affect the major …

Unconventional structured semiconductors and their applications in optoelectronics and photovoltaics
… electroless etching technique is used to produce porous GaN (PGaN), which is of particular interest for optoelectronics due to its large direct bandgap (3.4 eV). PGaN is also promising for use as a substrate for epitaxial growth and for chemical and biosensing. Several possible applications for …

Electrodeless electro hydrodynamic printing of personalized drug dosages
… unit dosages were prepared by precisely loading porous hydroxy methylcellulose film matrix with controlled drops of model drugs dissolved in lowly volatile polyethylene glycol carrier. Dissolution tests were performed following United States Pharmacopeia (USP) protocol, and the drug release data …

Adsorption Studies of Polysaccharides and Phospholipids Onto Cellulose
Interactions between biomolecules and cellulose films at solid/liquid interfaces was studied by surface plasmon resonance spectroscopy (SPR), quartz crystal microbalance with dissipation monitoring (QCM-D) and in situ atomic force microscopy (AFM) measurements. This dissertation shows the porous …
