Abstract: Atomic layer deposition (ALD) or ALD-like deposition processes are used to fabricate dilute nitride III-V semiconductor materials. A first composition of process gases may be caused to flow into a deposition chamber, and a group V element other than nitrogen and one or more group III elements may be adsorbed over the substrate (in atomic or molecular form). Afterward, a second composition of process gases may be caused to flow into the deposition chamber, and N and one or more group III elements may be adsorbed over the substrate in the deposition chamber. An epitaxial layer of dilute nitride III-V semiconductor material may be formed over the substrate in the deposition chamber from the sequentially adsorbed elements.

Abstract: Dilute nitride III-V semiconductor materials may be formed by substituting As atoms for some N atoms within a previously formed nitride material to transform at least a portion of the previously formed nitride material into a dilute nitride III-V semiconductor material that includes arsenic. Such methods may be employed in the fabrication of photoactive devices, such as photovoltaic cells and photoemitters. The methods may be carried out within a deposition chamber, such as a metalorganic chemical vapor deposition (MOCVD) or a hydride vapor phase epitaxy (HVPE) chamber.

Abstract: Syringes and methods of using are described which protect materials within the syringe barrel cavity from contaminants and photo-chemical degradation. A syringe is provided having an inspection window for viewing medications or other materials within the cavity of a syringe barrel. The syringe barrel and other syringe components may be colored, opaque, darkened, amber, tinted; or the syringe barrel may have applied thereto polarizing filters; or materials having light polarizing properties can be used to manufacture the syringe barrel and other syringe components of the syringe to cancel particular components of light.

Abstract: Syringes and methods of using are described which protect the syringe barrel cavity from contaminants. A first syringe is formed with a corrugated sheath or non-corrugated sheath which is positioned internal or external to the syringe barrel cavity. A second syringe is formed with a syringe barrel having a straight segment and a corrugated segment having the forward face of the plunger handle member molded to the rearward terminus of the corrugated segment of the syringe barrel. A third syringe is formed from mating syringe barrel and plunger member walls. The walls of the mating syringe barrel and plunger member are concentric and slide relative to each other while maintaining an enclosure around the plunger shaft. A fourth syringe is formed from inner and outer concentric syringe barrel walls mating with the walls of a plunger member. The mating walls are concentric and slide relative to each other while maintaining an enclosure around the plunger shaft.

Abstract: Syringes and methods of using are described which protect the syringe barrel cavity from contaminants. A syringe is formed with an end cap contaminant shield having an extension wall that is mated with the rearward end opening of the syringe barrel cavity. Alternatively, the end cap contaminant shield can be provided with a flat design without the extending wall and is bonded or molded to the rearward end terminus of the syringe barrel. The end cap contaminant shield designs are provided with an opening defining the shape of the cross-section of the plunger shaft.

Abstract: A portable headrest which includes two padded tubular segments connected by a flexible web is described. Each tubular segment has a free end portion that includes fasteners to permit the user to connect these free end portions adjustably and detachably to each other. The headrest may be made from one piece of fabric sewn to create a tubular structure having five compartments. The innermost compartment is the web. The two compartments immediately adjacent the web are the padded tubular segments. The two outermost compartments are the free end portions. Once the free end portions are connected, the user places the headrest such that the tubular segments are positioned adjacent opposing lateral sides of the back of his head. The headrest thus supports the user's head against uncomfortable rotation and tilting so that the user can sit and/or sleep while sitting more comfortably without straining his neck.

Abstract: A photocatalytic oxidation purification system includes an ultra violet light source and a filter that comprises a pleated wire mesh substrate with a nanophase metal oxide oxidation catalyst suspended on the substrate, wherein the catalyst is applied without an adhesive using an electromechanical plating process. As a fluid containing organic contaminants is directed through the filter in the presence of ultra violet light from the light source, the catalyst oxidizes and decomposes the organic contaminants into environmentally harmless components. Methods of making the purification system including preparing a solution of catalyst and applying the catalyst without adhesive binding material to the filter substrate electromagnetically.
