Multifunctional Matrix‐Activated Electrodes Enabling Efficient Proton Transport and Durable Low‐Pt Operation for High‐Temperature Proton Exchange Membrane Fuel Cells

Advanced Energy Materials, EarlyView.
This work introduces a CeHP‐enabled multifunctional matrix‐activated electrode (MME) for high‐temperature PEM fuel cells, forming an electrochemically and mechanically functional matrix within the catalyst layer. The design increases peak power density by 38% and reduces voltage decay by 62% at 240 °C, while using only 40% of the Pt loading of a ...

Surface‐Functionalized MXene for Enhanced Photocatalytic CO2 Reduction

Advanced Energy Materials, EarlyView.
Poly(catechol/p‐cresol)‐functionalized MXene (f‐MXene) enhances oxidation stability while preserving conductivity, enabling efficient interfacial electron transfer in a Cu/f‐MXene/reduced TiO2 photocatalyst. Strong Cu–f‐MXene synergy promotes CO2 activation and selective CH4 production, achieving a CH4 yield of 18.1 µmol g−1 (>200 × vs.

Atypical Cerebellar Responses are Associated with Altered Neural Habituation during Sensory Stimulation in Autism

Autism Research, EarlyView.
ABSTRACT Sensory processing atypicalities are highly prevalent in autistic youth; yet, the neural mechanisms underlying these differences are not well understood. While the cerebellum plays a key role in sensorimotor coordination and is structurally and functionally atypical in the autistic brain, it has been overlooked in research investigating ...

Acidogenic fermentation of pretreated food waste under psychrophilic conditions for volatile fatty acids production

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract Mixed‐culture fermentation generally produces volatile fatty acids (VFAs) as a mixture of C2–C6 acids. Among operational parameters, temperature has a distinct effect on the microorganisms' metabolic activity, which can shift the composition of the metabolites.

Functional Diversity and Oleaginous Potential of Fungal Strains From Hawaiian Soil Ecosystems

Biotechnology and Bioengineering, EarlyView.
ABSTRACT Fungi represent an important but underexplored resource for microbial lipid production, including nutritionally valuable polyunsaturated fatty acids. Hawaiian soils, shaped by volcanic parent materials and strong environmental gradients, provide a unique setting for discovering functionally diverse fungal strains with distinct metabolic traits.
