Online quadrupole mass spectrometry and gas chromatography were used to monitor the effluent gases from the semi-batch stirred autoclave reactors. Stearic, oleic, and palmitic acids were employed as model compounds. A catalyst lifetime exceeding 2200 turnovers for oleic acid deoxygenation was demonstrated at 300 °C and 15 atm under 10% H2. The initial decarboxylation rate of palmitic acid under 5% H2 decreases sharply with increasing initial concentration; in contrast, the initial decarbonylation rate increases linearly, indicative of first-order kinetics. Scale-up of diesel-range hydrocarbon production was investigated by increasing the reactor vessel size, initial FA concentration, and FA/catalyst mass ratio. Lower CO2 selectivity and batch productivity were observed at the larger scales (600 and 5000 mL), primarily because of the h...}, number={12}, journal={ENERGY & FUELS}, author={Ford, Jeffrey P. and Thapaliya, Nirajan and Kelly, M.

Astringency is thought to be caused by interaction of food components with saliva, often leading to aggregate formation. Such interactions decrease saliva lubrication, form rough particles, and probably increase friction on oral surfaces – changing mouth-feel. Dynamic in vitro models were constructed to reproduce the likely interaction of whey proteins with saliva in the mouth during the course of beverage ingestion. Aggregate formation in the models was examined for numerous whey protein solutions under different conditions. Trends observed in the models were consistent with previous reported sensory evaluations of whey protein astringency. For example, maximum turbidity changed little in the models with increasing protein concentration, consistent with literature describing little increase in astringency with increasing protein concentration. Modelling mouth conditions, to measure protein–saliva interactions, related to astringency better than mixing saliva and protein in simple ratios.}, number={8}, journal={INTERNATIONAL DAIRY JOURNAL}, author={Andrewes, P. and Kelly, M. and Vardhanabhuti, B. and Foegeding, E.

These nanoparticles were prepared by contacting Pd(hfac)2 dissolved in L-CO2 with the alumina at 6.9 MPa and 28.5 °C and then slowly venting gaseous CO2 until L-CO2 was completely evaporated. After depressurization to remove the CO2 and unabsorbed Pd(hfac)2, the impregnated Pd(hfac)2 was reduced in hydrogen at a relatively low temperature of 75 °C. The adsorption isotherm of Pd(hfac)2 on γ-alumina suggests a weak interaction between the organometallic compound and the support. The average Pd particle size on the low-surface-area α-alumina, measured by scanning electron microscopy, increased from 13.1 ± 3.5 to 59.9 ± 11.3 nm, and the metal dispersion, measured by pulsed CO chemisorption, decreased from 11 to 3%, as the Pd loading on the alumina was increased from 0.15 to 1.54 wt %.

At low deposition temperatures (25-250 °C), TDEAHf directly reacts with the Si-H surface, resulting in partial removal of Si-H bonds and formation of a four-membered Si-O-Hf-Si bonding structure that can rapidly oxidize. The hydrogen removal process is observed to continue through many cycles of TDEAHf/H 2 O exposure, signifying continued reactivity of the Hf precursor with the silicon surface. Density functional theory calculations have been performed for various reactions between tetrakis(dimethylamino) hafnium and Si-H surfaces, and several possible reaction pathways for hydrogen removal have been identified and analyzed. The calculations suggest that hydrogen removal proceeds by H abstraction by an amine ligand of the Hf precursor and that the abstraction reaction is made more facile by the presence of OH on the otherwise H-terminated Si surface.}, number={21}, journal={CHEMISTRY OF MATERIALS}, author={Kelly, MJ and Han, JH and Musgrave, CB and Parsons, GN}, year={2005}, month={Oct}, pages={5305–5314} } @misc{parsons_chambers_kelly_2003, title={High dielectric constant metal silicates formed by controlled metal-surface reactions}, volume={6,521,911}, number={2003 Feb. 18}, publisher={Washington, DC: U.S. Patent and Trademark Office}, author={Parsons, G.

Films are characterized by x-ray photoelectron spectroscopy, infrared absorption, and capacitance versus voltage analysis. We find that when we oxidize La metal sputter deposited on Si substrates, it reacts with the silicon substrate to form La silicate. La films as thick as 300 Å will react completely with Si under moderate oxidation conditions (900 °C for 10 min) suggesting a very rapid silicidation reaction between La and Si. Under some processing conditions the as-deposited films contain a small La2O3 component that reduces to La silicate upon anneal at high temperatures. La-silicate films do not phase separate into La2O3 and SiO2 upon annealing at 1050 °C, and their resistance to H2O incorporation depends critically on the oxidation temperature.

Interface reactions that occur during deposition and during postdeposition treatment are observed and compared for PVD and chemical vapor deposition (CVD) yttrium oxides and CVD aluminum-oxide systems. Silicon diffusion, metal-silicon bond formation, and reactions involving hydroxides are proposed as critical processes in interface layer formation. For PVD of yttrium silicate, oxidation is thermally activated with an effective barrier of 0.3 eV, consistent with the oxidation of silicide being the rate-limited step. For CVD aluminum oxide, interface oxidation is consistent with a process limited by silicon diffusion into the deposited oxide layer.}, number={9}, journal={JOURNAL OF APPLIED PHYSICS}, author={Niu, D and Ashcraft, RW and Kelly, MJ and Chambers, JJ and Klein, TM and Parsons, GN}, year={2002}, month={May}, pages={6173–6180} } @article{gougousi_kelly_parsons_2002, title={The role of the OH species in high-k/polycrystalline silicon gate electrode interface reactions}, volume={80}, ISSN={["1077-3118"]}, url={http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcAuth=ORCID&SrcApp=OrcidOrg&DestLinkType=FullRecord&DestApp=WOS_CPL&KeyUT=WOS:000175904600044&KeyUID=WOS:000175904600044}, DOI={10.1063/1.1485122}, abstractNote={In this letter, reactions occurring at the interface between polycrystalline silicon (poly-Si) and LaSiOx high-dielectric-constant (high-k) insulating layers are characterized using x-ray photoelectron spectroscopy.

Amorphous silicon was deposited on top by plasma-enhanced chemical vapor deposition from silane, followed by anneal at 650–1050 °C. We show that if the dielectric layer is exposed to sufficient water vapor before polysilicon deposition, annealing at 1050 °C for 10 s is sufficient to completely oxidize ∼25 Å of deposited silicon.
