The Optimal Design of Heat Sinks: A Review [PDF]

open access: yesJournal of Applied and Computational Mechanics, 2020
Heat sinks are used in industrial equipment to dissipate the excess heat from their heat-generating parts to the ambient. In the last few years, efforts on manufacturing electronic or mechanical devices with less weight, space, and lower cost were spent.

An intracellular transporter mitigates the CO2‐induced decline in iron content in Arabidopsis shoots

open access: yesFEBS Letters, EarlyView.
This study identifies a gene encoding a transmembrane protein, MIC, which contributes to the reduction of shoot Fe content observed in plants under elevated CO2. MIC is a putative Fe transporter localized to the Golgi and endosomal compartments. Its post‐translational regulation in roots may represent a potential target for improving plant nutrition ...

Structural instability impairs function of the UDP‐xylose synthase 1 Ile181Asn variant associated with short‐stature genetic syndrome in humans

open access: yesFEBS Letters, EarlyView.
The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...

An experimental study on the filtration performance of a poly-alpha-olefin-compatible expanded polytetrafluoroethylene high-efficiency particulate air filter

open access: yesSouth African Journal of Chemical Engineering, 2022
Filter media made of expanded polytetrafluoroethylene filters are known to be incompatible with poly-alpha-olefin or any oil-based challenge particles, and thus, filters made of expanded polytetrafluoroethylene had limited use in pharmaceutical ...
