Abstract: Methods for carrying out high temperature reactions such as biomass pyrolysis or gasification using solar energy. The biomass particles are rapidly heated in a solar thermal entrainment reactor. The residence time of the particles in the reactor can be 5 seconds or less. The biomass particles may be directly or indirectly heated depending on the reactor design. Metal oxide particles can be fed into the reactor concurrently with the biomass particles, allowing carbothermic reduction of the metal oxide particles by biomass pyrolysis products. The reduced metal oxide particles can be reacted with steam to produce hydrogen in a subsequent process step.

Abstract: Embodiments of the present disclosure provide novel compositions, methods of use and methods for single composition, multi-dose, thermostable vaccine formulations. In certain embodiments, the present disclosure provides compositions and methods for dehydrating immunogenic agents in the presence of glass-forming agents, and coating the particles formed by the glass-forming agents. In other embodiments, the present disclosure provides for generating compositions for administering an immunogenic composition to a subject multiple times using a single immunogenic composition capable of time-release administration. In other embodiments, single-dose immunogenic agent-containing particles can be directed to two or more pathogens. In other embodiments, incompatible immunogenic agents against two or more different pathogens of immunogenic agent-containing particles disclosed herein can be mixed together and coated for timed-release administration to produce single-administration formulations capable of eliciting an immune response to the two or more pathogens in a subject.

Abstract: A method for forming an oxygen reduction reaction (ORR) catalyst (200, 900) may include providing a carbon (210, 910) supported platinum nanoparticle (220, 920) substrate (Pt/C) (110) and applying a tungsten nitride (WN) film (940) onto the surface of the Pt/C substrate (210, 220, 910, 920) using atomic layer deposition (ALD) (120). The Pt/C substrate (210, 220, 910, 920) with the WN film (940) may then be oxidized at a low temperature (130) and annealed at a high temperature in order to reduce WN to metallic tungsten (W) (140). The metallic W forms a blocking layer (230, 930) over coarse Pt nanoparticles (220, 920) and improves the activity and the durability of the Pt/C catalyst (900, 200) when used in fuel cells or related applications.
