Hydrogen diffusion and trapping in nanocrystalline tungsten
(Elsevier Science, 2015-01)
The hydrogen behavior in nanocrystalline W (ncW) samples with grain size of 5 and 10 nm is studied using Molecular Dynamics (MD) with a bond order potential (BOP) for the W-H system. The dependence of the hydrogen diffusion ...
Effects of Tungsten and Molybdenum on Sucrose Content and Hydrolytic Enzymes of Immature SugarcaneTítulo en español.
(University of Puerto Rico Mayagüez Campus Agricultural Experiment Station, 1965)
Nuclear properties of Tungsten under 14 MeV neutron irradiation for fusion-fission hybrid reactors
(Elsevier, 2020-11)
Monte-Carlo simulations were performed to study the behavior of Tungsten under 14 MeV neutron irradiation. At this energy, its multiplicative properties become relevant, especially due to the ðn; 2nÞ channel, but many other ...
Structure and Vibrational Properties of Potassium-Promoted Tungsten Oxide Catalyst Monomeric Sites Supported on Alumina (K2O/WO3/Al2O3) Characterized Using Periodic Density Functional Theory
(American Chemical Society, 2018-10)
Al2O3-supported tungsten oxide catalysts have been instrumental in many industrially relevant reactions and their reactivity is controlled by their molecular structure. In turn, their molecular structure has primarily been ...
PH-dependent bioavailability, speciation, and phytotoxicity of Tungsten (W) in Soil Affect Growth and Molybdoenzyme Activity of Nodulated Soybeans
(American Chemical Society, 2018-06)
Increasing use of tungsten (W)-based products opened new pathways for W into environmental systems. Due to its chemical alikeness with molybdenum (Mo), W is expected to behave similarly to its "twin element", Mo; however, ...
Highly selective tungstate transporter protein TupA from Desulfovibrio alaskensis G20
(Nature Publishing Group, 2017-12)
Molybdenum and tungsten are taken up by bacteria and archaea as their soluble oxyanions through high affinity transport systems belonging to the ATP-binding cassette (ABC) transporters. The component A (ModA/TupA) of these ...
The Interrelation Poverty-Unemployment from the Theory of Entropy in Modern Societies
(Institute of Electrical and Electronics EngineersPE, 2021-08-19)
In this paper, a mathematical model based on uncertainties to describe the potential interrelation between unemployment and poverty by using the Shannon’s entropy is presented. Essentially, when social systems that are ...
Hyper Secure Cognitive Radio Communications in an Internet of Space Things Network Based on the BB84 Protocol
(Institute of Electrical and Electronics EngineersPE, 2020-11-11)
Once constellation of satellites are working in a collaborative manner, the security of their messages would have to be highly secure from all angles of scenarios by which the praxis of eavesdropping constitutes a constant ...
