Entropy‐Driven Design of Low‐Melting‐Point Alloys via Compositionally Complex Strategy

open access: yesAdvanced Engineering Materials, EarlyView.
Conventional low‐melting‐point alloys (LMPAs) are limited by a narrow compositional space and inherent property trade‐offs. This review presents an entropy‐driven design strategy that overcomes these limitations, ushering in a new class of low‐melting‐point compositionally complex alloys (LMCCAs).

On the dissipation of kinetic energy in the atmosphere

open access: yesTellus, 1963
After a discussion of some general aspects of the atmospheric energy cycle results from computations of the frictional changes of kinetic energy are given. Large losses of kinetic energy are found in the boundary layer and in the region near the tropopause below the level of maximum wind.

High‐Entropy Alloy Interlayers Toward Advanced Joining for High‐Performance Structural Applications: Current Progress and Emerging Challenges

open access: yesAdvanced Engineering Materials, EarlyView.
HEA interlayers offer a versatile route for joining high‐performance structural materials. Their compositional and structural design regulates interfacial reactions, suppresses brittle IMCs, and improves metallurgical bonding. Sandwich interlayers further integrate defect healing with precipitation strengthening, enabling improved strength–ductility ...

Cryogenic Deformation Behavior of TiAl and Insights Into Embrittlement After High‐Temperature Exposure Combined With Secondary Ion Mass Spectroscopy of Near Surface Chemistry

open access: yesAdvanced Engineering Materials, EarlyView.
Near‐surface deuterium enrichment profiles for different microstructural types of TiAl after exposure at 700 °C in a heavy water‐containing environment. The deuterium levels are significantly higher than expected from natural occurrence, indicating that the heavy water dissociated during the exposure treatment and entered the specimens.

Fate of Sulfoxaflor in a Tomato Plant and Soil and Its Efficacy Against Whitefly (Bemisia tabaci) and Aphid (Myzus persicae) [PDF]

open access: yesArab Universities Journal of Agricultural Sciences
The insecticide sulfoxaflor, a member of the sulfoximine family, is effective against a wide range of sap-feeding insects. However, information on its residual behavior under open-field conditions remains limited.

Historical Foundation and Practical Guideline for Ferroelectric Switching Kinetic Studies

open access: yesAdvanced Functional Materials, EarlyView.
The P and U pulses in the conventional PUND measurements are not identical because of the interplay between switching current and the measurement circuit components. This circuit effect can lead to a shift in polarization transients and misinterpreted physics in the switching kinetics.

A note on kinetic energy, dissipation and enstrophy [PDF]

open access: yesPhysics of Fluids, 1999
We show that the dissipation rate of a Newtonian fluid with constant shear viscosity has three constituents from dilatation, vorticity, and surface strain. The last one, being associated with the most complicated manners of fluid deformation, only contributes to the change of internal energy but not that of kinetic energy.
