Entropy‐Driven Design of Low‐Melting‐Point Alloys via Compositionally Complex Strategy
Advanced 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 VERIFICATION OF UPPER-AIR WINDS BY VERTICAL SHEAR AND EXTREMES
Monthly Weather Review, 1961 Abstract The existence of undetected errors in recorded wind observations may have a biasing influence on a statistical study. In the progress of some studies it has been found necessary to reexamine the data being used. A series of upper-air winds has been checked by using available listings of vertical shear and extreme winds. The developed procedure

Advanced Engineering Materials, EarlyView.This study proposes a potential device design for joint cartilage replacement. Silica‐polytetrahydrofuran (SiO2‐PolyTHF) hybrids with customizable mechanical properties were developed to mimic the characteristics of a natural meniscus. These were synthesized through a two‐pot sol–gel hybrid process.

Crosswise Wind Shear Represented as a Ramped Velocity Profile Impacting a Forward-Moving Aircraft
International Journal of Aerospace Engineering, 2019 Abrupt changes in wind velocities over small distances in a lateral or vertical direction can produce wind shear which is known to have serious effects upon the performance of an aircraft.
