Inverse hall-petch relationship in nanocrystalline tantalum
(Elsevier Science SA, 2013-09-15)
Tantalum polycrystals (grain sizes varying from 2.5 to 30 nm) generated by Voronoi tessellation were subjected to tension and compression under uniaxial strain loading at strain rates on the order of 108–109 s−1 using ...
Discrete Kinetic Models from Funneled Energy Landscape Simulations
(Public Library of Science, 2012-12)
A general method for facilitating the interpretation of computer simulations of protein folding with minimally frustrated energy landscapes is detailed and applied to a designed ankyrin repeat protein (4ANK). In the method, ...
Manganese (II,III) Oxide-Activated Carbon Black Supported PtRu Nanoparticles for Methanol Electrooxidation in Acid Medium
(Wiley-VCH Verlag, 2018-05-04)
In this work, PtRu nanoparticles supported on hybrid manganese (II,III)-carbon composites were prepared by a microwave-assisted polyol process in ethylene glycol. The obtained PtRu/(100-x) C.xMn 3 O 4 catalysts were ...
Encapsulation of lactase in Ca(II)-alginate beads: Effect of stabilizers and drying methods
(Elsevier Science, 2017-10)
The purpose of the present work was to analyze the effect of trehalose, arabic and guar gums on the preservation of β-galactosidase activity in freeze-dried and vacuum dried Ca(II)-alginate beads. Freezing process was also ...
Magnetic viscosity in iron-rhodium nanowires
(Elsevier Science Sa, 2017-03-09)
Noble/transition bimetallic nanowires of nominal composition Fe90Rh10 are AC electrodeposited into 20 nm diameter hexagonally self-assembled alumina nanopores. Nanowires about 18 nm in diameter and 1 μm long are polycrystalline ...
Truncation of a β-barrel scaffold dissociates intrinsic stability from its propensity to aggregation
(Cell Press, 2012-11)
Δ98Δ is a functional all-β sheet variant of intestinal fatty acid binding protein (IFABP) that was generated by controlled proteolysis. This framework is useful to study the molecular determinants related to aggregation ...
Fracture and thermal behaviour of biomass ash polypropylene composites
(Sage Publications Ltd, 2014-07)
In this work, the fracture and thermal behaviour of environmentally friendly composites based on polypropylene (PP), an olefin block copolymer (OBC) and ash from biomass combustion was investigated. PP/OBC/ash composites ...
Meiosis and Development of the Embryo Sac in Gunnera insignis (Oersted) D.C. (Halorhagaceae)Título en español.
(University of Puerto Rico Mayagüez Campus Agricultural Experiment Station, 1962)
Methane production by mechanochemical processing of MgH2-Li2CO3 as sources of H2 and CO2 at room temperature
(Elsevier, 2020-09)
The reutilization of CO2 to produce valuable chemical fuels is an attractive approach to reduce the greenhouse effect and global warming. In this work, the room temperature production of CH4/H2 fuel mixtures via mechanochemical ...
