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.

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

FEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

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

Copper catalyzed one-pot synthesis of beta-ketophosphine oxides from ketones and H-phosphine oxides

, 2017
A facile and efficient copper catalyzed one-pot method has been developed for the formation of beta-ketophosphine oxides from ketones and H-phosphine oxides under air at room temperature, in which vinylhydrazinedicarboxylate was formed as the key ...

Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation

FEBS Letters, EarlyView.
Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.

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 ...
