Abstract:
Described herein are devices for providing drinking fluid from feed sources comprising: a first reservoir, a filter for mechanically removing particles and a second reservoir for receipt of the processed feed fluid. A continually disinfecting element is disposed in either or both reservoirs to remove additional materials from the fluid. Drinking fluid is provided in a portable device. Optional light sources are provided to interact with the disinfecting elements and/or provide an indication of the contained suitability of such disinfecting elements. A method for creating drinking fluid from a feed source is also disclosed.
Abstract:
Described herein are coatings based on a hydrophobic polymer matrix and hydrophobic nanoparticles that provide a damage tolerant hydrophobic, superhydrophobic, and/or snowphobic capability, wherein the nanoparticles can comprise modified and phyllosilicate nanoclays. The micro and nano roughness of the composite surface is described. Methods of creating snow resistant materials by employing the aforementioned coatings are also described.
Abstract:
Described herein are heterogeneous materials comprising a p-type semiconductor comprising two metal oxide compounds of the same metal in two different oxidation states and an n-type semiconductor having a deeper valence band than the p-type semiconductor valence bands, wherein the semiconductor types are in ionic communication with each other. The heterogeneous materials enhance photocatalytic activity.
Abstract:
Some embodiments disclosed herein include a lighting apparatus having a composite. The composite may include a first emissive layer and a second emissive layer. The first emissive layer may include a first garnet phosphor having a common dopant. The second emissive layer may include a second garnet phosphor having the common dopant. In some embodiments, the first emissive layer and the second emissive layer are fixed together. Some embodiments disclosed herein include efficient and economic methods of making the composite. The method may include, in some embodiments, sintering an assembly that includes pre-cursor materials for the first emissive layer and the second emissive layer.
Abstract:
Described herein are elements comprising a p-type semiconductor comprising mixed valence oxide compounds and an n-type semiconductor having a deeper valence band than the p-type semiconductor valence bands wherein the semiconductor types are in ionic communication with each other. The elements enhance photocatalytic activity.
