Quantifying the effects of airflow distortion on anemometer wind speed measurements from merchant ships [PDF]
, 2003 Anemometers on Voluntary Observing Ships (VOS) are usually located above the bridge in a region where the effects of air flow distortion, created by the presence of the ship, may be large.

Advanced Engineering Materials, EarlyView.The tribological behavior of 100Cr6 steel spheres textured via Vickers microindentation is evaluated under lubricated sliding by varying both dimple size and density. Fine and dense textures significantly reduce friction across all lubrication regimes, while large dimples increase it.

Lattice Distortion and Phase Stability of Pd-Doped NiCoFeCr Solid-Solution Alloys
Entropy, 2018 In the present study, we have revealed that (NiCoFeCr)100−xPdx (x= 1, 3, 5, 20 atom%) high-entropy alloys (HEAs) have both local- and long-range lattice distortions by utilizing X-ray total scattering, X-ray diffraction, and extended X-ray ...

Pressure-Induced Suppression of Static Disorder and Lattice Distortion in Pyrochlore Bi2Ru2O7
Bi2Ru2O7 is a weak metal pyrochlore with static disorder from lone-pair electrons. The suppression of static disorder can be observed by in situ Raman spectroscopy, and the abnormal turning point in resistivity can be found at high pressure.

Advanced Engineering Materials, EarlyView.This study presents a reversible temperature sensor with high switching ratio, ∼103. The device is fabricated using PET‐ITO and carbon nanotube dispersions in alkane. Considering its application in cold chain logistics, a proof‐of‐concept with LED is showcased. Thus, a temperature drop below the threshold temperature (crystallization temperature of the
