Optimization of transition metal nanoparticle- phosphonium IL composite catalytic systems for deep hydrogenation and hydrodeoxygenation reactions
(Royal Society of Chemistry, 2015)
A variety of metal nanoparticle (NP)/tetraalkylphosphonium ionic liquid (IL) composite systems were evaluated as potential catalysts for the deep hydrogenation of aromatic molecules. Particles were synthesized by reducing ...
Modelling User Collaboration in Social Networks Using Edits and Comments
(ACM New York, NY, USA, 2016-07-13)
Research has shown that in Q&A social networks, collaboration between respondents results in quality answers. Since good answers are required to keep any Q&A social network active, it is important to understand the ...
Isolation of Carboxylic Acid-Protected Au25 Clusters using a Borohydride Purification Strategy
(American Chemical Society, 2015)
We report the synthesis of 11-mercaptoundecanoic acid (11-MUA) and 16-mercaptohexadecanoic acid (16-MHA) protected Au25 clusters with moderate yields (∼15%) using a NaBH4 purification strategy. UV–vis spectroscopy, ...
Investigation of the stability of glass-ceramic composites containing CeTi2O6 and CaZrTi2O7 after ion implantation
(Elsevier, 2017)
Glass-ceramic composite materials have been investigated for nuclear waste sequestration applications due to their ability to incorporate large amounts of radioactive waste elements. A key property that needs to be understood ...
In situ X-ray Absorption Spectroscopic Study of Fe@FexOy/Pd and Fe@FexOy/Cu Nanoparticle Catalysts Prepared by Galvanic Exchange Reactions
(American Chemical Society, 2015)
Fe@FexOy core–shell nanoparticles have been previously shown to be a versatile support for catalytic metals such as Pd and Cu. However, the resulting structure, metal speciation, and performance of such catalysts in catalytic ...
Putative mixotrophic nitrifying-denitrifying Gammaproteobacteria implicated in nitrogen cycling within the ammonia/oxygen transition zone of an oil sands pit Lake
(Frontiers, 2019-10-24)
Anthropogenically-impacted environments offer the opportunity to discover novel microbial species and metabolisms, which may be undetectable in natural systems. Here, a combined metagenomic and geochemical study in Base ...
Complexity or simplicity? Designing product pictures for advertising in online marketplaces
(Pergamon, 2016-01-31)
In online marketplaces, many sellers highlight product and service information directly within product pictures for advertising purposes. Such a strategy increases the visual complexity of the picture and provides more ...
Following the Thermal and Chemical Activation of Supported Au Clusters using X-ray Absorption Spectroscopy
(Royal Society of Chemistry, 2016)
Al2O3-supported Au25(SC8H9)18 clusters with various Au loadings were thermally and chemically treated in order to determine the most efficient method towards the removal of thiolate stabilizers while avoiding unwanted ...
Investigation of the Thermal Stability of NdxScyZr1−x−yO2−δ Materials Proposed for Inert Matrix Fuel Applications
(American Chemical Society, 2016)
Inert matrix fuels (IMF) consist of transuranic elements (i.e., Pu,
Am, Np, Cm) embedded in a neutron transparent (inert) matrix and can be
used to “burn up” (transmute) these elements in current or Generation IV
nuclear ...
