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

open access: yesAdvanced 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

open access: yesAdvanced 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.

LA-ICP-MS of two AMG-positive breast lobules.

open access: yes, 2020
Boxes in the hematoxylin-eosin (HE) stained sections in the upper row show the region of LA-ICP-MS analysis. Phosphorus (P) abundance indicates cellular density. Selected regions stained with autometallography (AMG) are indicated in the LA-ICP-MS mercury

Membrane‐aided simultaneous reaction–separation for liquid phase products

open access: yesAIChE Journal, EarlyView.
Abstract Conventionally, reaction and separation are conducted as separate steps in liquid‐phase manufacturing, with products formed during reaction and subsequently separated from unreacted reagents, solvents, and byproducts. Integrating these steps into a simultaneous reaction–separation process can improve efficiency and reduce costs.

Petrogenesis Research of Basic Rock in the Hongliugou Area of the Altun Orogen Based on Baddeleyite Chronology and Whole-Rock Geochemical Analyses

open access: yesYankuang ceshi
Previous studies suggest that the Alton Block may have participated in the breakup of the Rodinia supercontinent, however, there have been no prior reports of intraplate basic-ultrabasic rock bodies in the region.

pH‐Responsive Ultrasmall Iron Oxide Nanoassemblies for Activatable T2/T1 Magnetic Resonance Imaging

open access: yesAdvanced NanoBiomed Research, EarlyView.
This research reports a pH‐responsive ultrasmall iron oxide nanoparticle (USIONs)/polymer nanoassemblies for activatable magnetic resonance imaging. Amphiphilic diphosphonic acid block copolymers compactly encapsulate USIONs to generate T2‐weighted contrast at physiological pH, while acidic conditions trigger disassembly, activating T1‐weighted ...
