Abstract: Structures of a particle containing a core and at least one shell, a metal oxide material of which is necessarily doped to ensure protection of a material of the core from photodegradation. The core can include any of a thermochromic material, a phase-change material, and a judiciously defined auxiliary material that in turn contains organic and/or polymeric material. Derivative products utilizing a plurality of such particles. Methodologies for producing such particles and derivative products.

Abstract: Leachate remediation is performed by synergistic chemical oxidation and photocatalytic-oxidation enhancer system (SCOPES) of municipal landfill leachate to a level that is safe for disposal within regulatory guidelines. The physico-chemical (chemical, spectroscopic, elemental, microstructural and thermal) characteristics of the pre- and post-treated landfill leachate have been investigated to examine the utility of advanced oxidation (AO) processes such as SCOPES to decontaminate the municipal landfill leachate and/or toxic organic wastewater. The experimental results demonstrated successful lowering of chemical oxygen demand (COD) and UV-Vis absorbance for constituent contaminants in the leachate and/or wastewater solutions.

Abstract: A ternary hydrogen storage system having a constant stoichiometric molar ratio of LiNH2:MgH2:LiBH4 of 2:1:1. It was found that the incorporation of MgH2 particles of approximately 10 nm to 20 nm exhibit a lower initial hydrogen release temperature of 150° C. Furthermore, it is observed that the particle size of LiBNH quaternary hydride has a significant effect on the hydrogen sorption concentration with an optimum size of 28 nm. The as-synthesized hydrides exhibit two main hydrogen release temperatures, one around 160° C. and the other around 300° C., with the main hydrogen release temperature reduced from 310° C. to 270° C., while hydrogen is first reversibly released at temperatures as low as 150° C. with a total hydrogen capacity of 6 wt. % to 8 wt. %. Detailed thermal, capacity, structural and microstructural properties have been demonstrated and correlated with the activation energies of these materials.
