Adsorption‐Engineered Hydrocarbon Ionomers for Durable Proton‐Exchange Membrane Fuel Cells

Advanced Materials, EarlyView.
Hydrocarbon ionomers suffer from oxidation‐driven interfacial degradation in PEM fuel cell cathodes, leading to catalyst instability. Here, adsorption‐engineered poly(fluorene) ionomers decouple interfacial anchoring from oxidative degradation, enabling strong catalyst–ionomer interactions while resisting electrochemical oxidation.

Poxvirus infection triggers remodeling of host m⁶A epitranscriptome and benefits from the m⁶A regulatory responses

Virology Journal
Background Understanding how host gene regulation responds to viral infection is essential for developing effective antiviral strategies. Emerging evidence suggests that host transcripts undergo dynamic chemical modifications to counteract viral invasion.

Modulation of miR‐23b Wnt/β‐catenin Axis Strengthens Endothelial Barrier Properties

Advanced Science, EarlyView.
Early blood‐brain barrier (BBB) disruption contributes to stroke and CNS disease pathology. miR‐23b was identified as a regulator of BBB integrity in brain endothelial cells. Inhibition of miR‐23b enhanced barrier‐associated properties, promoted repair‐related signaling, and reduced BBB leakage in experimental stroke models, supporting further ...

STRESS DISTRIBUTION IN THE MATERIAL AND DEVELOPMENT OF LOADS ON THE WALL DURING HOPPER FILLING

TASK Quarterly, 2003
Stress distributions developing in granular materials in hoppers during the process of filling is fundamental for an understanding of the phenomena observed in hoppers. Predictions of such stress distributions are therefore essential.

A Critical Time Window of Neocortex Modulation for Remote Fear Memory in Rats and Humans

Advanced Science, EarlyView.
This study identifies a delayed consolidation window around 18 h after fear learning in the mPFC essential for remote fear memory. VTA dopaminergic input during this window sustains remote memory in rats, while non‐invasive stimulation of homologous human mPFC at the corresponding time selectively weakens remote but not recent fear memory, revealing a ...

A NEW THREE PHASE INVERTER WITH LOW DISTORTION FOR UNINTERRUPTABLE POWER SUPPLY APPLICATIONS

Electrica, 2019
The ways of providing low distortion in inverter or UPS applications without using large and high cost filters are whether applying PWM technique [1] or producing several appropriate steps on the output waveform called as multilevel operation.

SYNTHESIS AND PROPERTIES OF EMULSIFIERS OF INVERT EMULSIONS BASED ON FATTY ACID MONOETHANOLAMIDES

Известия высших учебных заведений: Нефть и газ, 2018
The article discusses the results of synthesis of various derivatives of carboxylic acids and ethanolamine, namely monoethanolamides of stearic and tridecanoic acids. We used azeotropic distillation method for the synthesis. This research allows to value

Pre‐Regenerative Endothelial Cells Empowered by Antler Blood Exosomes Orchestrate Peripheral Nerve Repair

Advanced Science, EarlyView.
The pre‐regenerative vascular niche (PVN) is essential for nerve repair, yet its endothelial blueprint remains unclear. We identified angiogenic ECs (AECs) as the dominant pre‐regenerative subset and found that antler blood–derived exosomes (AB‐EXO) promote repair via IMP3.

Iron‐Mediated Release of Aged Dissolved Organic Carbon From Waterlogged Peatland Under Warming

Advanced Science, EarlyView.
This study conducts a five‐year in situ warming experiment in high‐altitude peatlands to examine dissolved organic carbon (DOC) release. The study shows that warming promotes the release of plant‐derived modern DOC in drained peatlands, but amplifies aquatic export of century‐old DOC from waterlogged peatlands via Fe‐mediated DOC mobilization—a ...
