Synthesis, characterization, and testing of supported Au catalysts prepared from atomically-tailored Au38(SC12H25)24 clusters.
Nearly monodispersed Au(38)(SC(12)H(25))(24) clusters (1.7 ± 0.2 nm) were synthesized using a modified Brust process while utilizing a "thiol etching" approach for the ligand exchange. HRTEM, MALDI, FTIR, and XAS analysis confirmed the formation of the 38-atom clusters in solution. This solution was used to impregnate a microporous TiO(2) support to give 0.7% Au(38)/TiO(2) catalyst. Subsequent ...
متن کاملSynthetic Models for the Cysteinate-Ligated Non-Heme Iron Enzyme Superoxide Reductase: Observation and Structural Characterization by XAS of an Fe-OOH Intermediate
Superoxide reductases (SORs) belong to a new class of metalloenzymes that degrade superoxide by reducing it to hydrogen peroxide. These enzymes contain a catalytic iron site that cycles between the FeII and FeIII states during catalysis. A key step in the reduction of superoxide has been suggested to involve HO2 binding to FeII, followed by innersphere electron transfer to afford an FeIII-OO(H)...
متن کاملSpectrally Adaptive Nanoscale Quantum Dot Sensors
The potential use of nanotechnology for hyperspectral (HS) and multispectral (MS) sensing and imaging is described in this article. It is noted how HS and MS sensors/imagers have great potential for a variety of applications important to the intelligence community; such applications range from monitoring chemical-agent production to identifying geographical terrain. It is also noted that, by se...
متن کاملGains from diversification on convex combinations: A majorization and stochastic dominance approach
By incorporating both majorization theory and stochastic dominance theory, this paper presents a general theory and a unifying framework for determining the diversification preferences of risk-averse investors and conditions under which they would unanimously judge a particular asset to be superior. In particular, we develop a theory for comparing the preferences of different convex combination...
متن کاملImproved immunogenicity of tetanus toxoid by Brucella abortus S19 LPS adjuvant.
BACKGROUND Adjuvants are used to increase the immunogenicity of new generation vaccines, especially those based on recombinant proteins. Despite immunostimulatory properties, the use of bacterial lipopolysaccharide (LPS) as an adjuvant has been hampered due to its toxicity and pyrogenicity. Brucella abortus LPS is less toxic and has no pyrogenic properties compared to LPS from other gram negati...
