An approach for preparing a vaccine using ultraviolet radiation is described. Aspects of this approach involve multiple iterations of inactivation of the vaccine using an ultraviolet radiation source at a set of different wavelengths and dosages. A recognition test of the vaccine using the set of different wavelengths and dosages is performed after the multiple iterations of inactivation. A controller compares results from the inactivation test and the recognition test to determine an area of acceptable radiation dosages and wavelengths generated from the ultraviolet radiation source that irradiate the live organisms without affecting efficacy and safety of the vaccine. The area of acceptable ultraviolet radiation dosages and wavelengths is representative of a difference between an ultraviolet radiation dosage that is required for inactivation and an ultraviolet radiation dosage that leads to a loss of recognition.

A metal-organic chemical vapor deposition (MOCVD) growth with temperature controlled layer is described. A substrate or susceptor can have a temperature controlled layer formed thereon to adjust the temperature uniformity of a MOCVD growth process used to epitaxially grow semiconductor layers. In one embodiment, the substrate and/or the susceptor can be profiled with a shape that improves temperature uniformity during the MOCVD growth process. The profiled shape can be formed with material that provides a desired temperature distribution to the substrate that is in accordance with a predetermined temperature profile for the substrate for a particular MOCVD process.

A solution for fabricating a structure including a light guiding structure is provided. The light guiding structure can be formed of a fluoropolymer-based material and include one or more regions, each of which is filled with a fluid transparent to radiation having a target wavelength, such as ultraviolet radiation. The region(s) can be created using a filler material, which is at least substantially enclosed by the fluoropolymer-based material and subsequently removed from each region. The structure can further include at least one optical element integrated into the light guiding structure.

A system capable of detecting and/or sterilizing surface(s) of an object using ultraviolet radiation is provided. The system can include a disinfection chamber and/or handheld ultraviolet unit, which includes ultraviolet sources for inducing fluorescence in a contaminant and/or sterilizing a surface of an object. The object can comprise a protective suit, which is worn by a user and also can include ultraviolet sources for disinfecting air prior to the air entering the protective suit. The system can be implemented as a multi-tiered system for protecting the user and others from exposure to the contaminant and sterilizing the protective suit after exposure to an environment including the contaminant.

A heterostructure for use in fabricating an optoelectronic device is provided. The heterostructure includes a layer, such as an n-type contact or cladding layer, that includes thin sub-layers inserted therein. The thin sub-layers can be spaced throughout the layer and separated by intervening sub-layers fabricated of the material for the layer. The thin sub-layers can have a distinct composition from the intervening sub-layers, which alters stresses present during growth of the heterostructure.

A semiconductor structure including an anodic aluminum oxide layer is described. The anodic aluminum oxide layer can include a plurality of pores extending to an adjacent surface of the semiconductor structure. A filler material can penetrate at least some of the plurality of pores and directly contact the surface of the semiconductor structure. In an illustrative embodiment, multiple types of filler material at least partially fill the pores of the aluminum oxide layer.
