Transferrin receptor 1‐mediated iron uptake supports thermogenic activation in human cervical‐derived adipocytes

FEBS Letters, EarlyView.
In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.

Amorphous Gallium‐Oxide‐Based Non‐Filamentary Memristive Device with Highly Repeatable Multiple Resistance States

Advanced Electronic Materials
A memristive device is presented based on a Ti/GaOx/W stack with an amorphous GaOx layer deposited at a low temperature (250 °C) using plasma‐enhanced atomic layer deposition. The device fabrication is compatible with a standard complementary metal oxide

Quantum size effects on magnetism in Eu2MnHfO6 nanoparticles: Role of surface-to-volume ratio, magnetic blocking, and magnetic phase transitions

Results in Physics
In this paper, we investigate the quantum size effects on Eu2MnHfO6 (EMHO) nanoparticles (NPs) synthesized via sol–gel and annealed at 500, 800, and 1000 °C.

Machine learning approaches to identify and design low thermal conductivity oxides for thermoelectric applications

Data-Centric Engineering, 2020
The search space for new thermoelectric oxides has been limited to the alloys of a few known systems, such as ZnO, SrTiO3, and CaMnO3. Notwithstanding the high power factor, their high thermal conductivity is a roadblock in achieving higher efficiency ...

Oxidation and low cycle fatigue life prediction [PDF]

, 1984
When a metallic material is exposed to a high temperature in an ambient atmosphere, oxidation takes place on the metallic surface. The formed oxides (both surface and grain boundary oxides) are mechanically brittle so that if the stress is high enough ...

Tau acetylation at K331 has limited impact on tau pathology in vivo

FEBS Letters, EarlyView.
We mapped tau post‐translational modifications in humanized MAPT knock‐in mice and in amyloid‐bearing double knock‐in mice. Acetylation within the repeat domain, particularly around K331, showed modest increases under amyloid pathology. To test functional relevance, we generated MAPTK331Q knock‐in mice.
