A Simulative Approach for the Prediction of Mesoscale Residual Stress Fields in Solution‐Strengthened Ferritic Ductile Iron

open access: yesAdvanced Engineering Materials, EarlyView.
This study presents a 3D representative volume element‐based simulation approach to predict mesoscopic residual stress and strain fields in silicon solid solution‐strengthened ductile cast iron. By modeling phase transformation kinetics with an enhanced Johnson–Mehl–Avrami–Kolmogorov model, the effects of varying cooling rates on residual stresses are ...

Influence of neutron emission on the charge distribution of final fragments from thermal-neutron-induced fission of 233U

open access: yesResults in Physics, 2018
We use a Monte Carlo simulation method to calculate the effect of neutron emission on the distribution of mass, charge and kinetic energy of final fragments (after they emit neutrons) from the thermal-neutron induced fission of 233U.

Density functional scheme for calculating the pair density

open access: yes, 2006
The density functional scheme for calculating the pair density is presented by means of the constrained-search technique. The resultant single-particle equation takes the form of the modified Hartree-Fock equation which contains the kinetic contribution ...

CALPHAD‐Guided Prediction and Interpretation of Phase Formation in Ta–Mo–Cr–Ti–Al Refractory High‐Entropy Alloys

open access: yesAdvanced Engineering Materials, EarlyView.
This study designs Ta–Mo–Cr–Ti–Al refractory high‐entropy alloys with a disordered body‐centered‐cubic A2 crystal structure aiming for improved ductility, lower density, and oxidation resistance. Four alloy compositions are identified by thermodynamic calculations.

Kinetic energy flows in activated dynamics of biomolecules [PDF]

open access: yesarXiv, 2020
Protein conformational changes are activated processes essential for protein functions. Activation in a protein differs from activation in a small molecule in that it involves directed and systematic energy flows through preferred channels encoded in the protein structure.

Sudden viscous dissipation of compressing turbulence

open access: yes, 2016
Compression of turbulent plasma can amplify the turbulent kinetic energy, if the compression is fast compared to the viscous dissipation time of the turbulent eddies.

Reactive Interaction and Wetting of Fe‐ and Mn‐Containing, Secondary AlSi Alloys with Manganese Oxide Ceramic Filter Material for Fe Removal

open access: yesAdvanced Engineering Materials, EarlyView.
Fe‐ and Mn‐containing AlSi alloys undergo aluminothermic reaction with Mn oxide in sessile‐drop and crucible experiments forming poor‐wetting Al2O3 while Mn enriches in the alloy. Primary Fe‐containing particles are preferentially attached to the Mn oxide.

Analysis of energy transfer in quantum networks using kinetic network approximations [PDF]

open access: yesarXiv, 2012
Coherent energy transfer in pigment-protein complexes has been studied by mapping the quantum network to a kinetic network. This gives an analytic way to find parameter values for optimal transfer efficiency. In the case of the Fenna-Matthews-Olson (FMO) complex, the comparison of quantum and kinetic network evolution shows that dephasing-assisted ...

Removing Homocoupling Defects in Alkoxy/Alkyl‐PBTTT Enhances Polymer:Fullerene Co‐Crystal Formation and Stability

open access: yesAdvanced Functional Materials, EarlyView.
PBTTT‐OR‐R, a C14‐alkoxy/alkyl‐PBTTT polymer derivative, is of substantial interest for optoelectronics due to its specific fullerene intercalation behavior and enhanced charge‐transfer absorption. Comparing this polymer with (S) and without (O) homocoupling defects reveals that PBTTT‐OR‐R(O) forms stable co‐crystals with PC61BM, while PBTTT‐OR‐R(S ...
