Spectrally Coordinated Plasmonic–Photothermal Photocatalysts for Mineralization of Mixed Indoor VOCs Under White LED Illumination

open access: yesAdvanced Materials, EarlyView.
A plasmonic–photothermal–photocatalytic hybrid comprising Cu(II)‐grafted TiO2, yolk–shell Au@SiO2, and reduced graphene oxide sheets (CuT/AuSi‐GS) harvests full‐spectrum white light‐emitting diode (LED) light via complementary photocatalytic oxidation, localized surface‐plasmon‐resonance‐induced electric‐field enhancement, and photothermal acceleration.

Pulsed Oxidative–Reductive Electrolysis Over Dual Cu and Co Single‐Atom Sites for Urea Electrosynthesis

open access: yesAdvanced Materials, EarlyView.
Alternating oxidative–reductive pulses synchronize CO2‐derived *CO and NH3‐derived *NHx intermediates over dual Cu and Co single‐atom sites, enabling urea and ethyl urea formation with a total C─N Faradaic efficiency of 42 ± 4%. In situ spectroscopy and theoretical calculations elucidate complementary Cu and Co functions, while oxidative controls ...

Elevated and atmospheric‐level methane consumption by soil methanotrophs of three grasslands in China

open access: yesGrassland Research, 2023
Background Methane (CH4) oxidation driven by soil aerobic methanotrophs demonstrates the capacity of grassland as a CH4 sink. Methods In this study, we compared the oxidation characteristics of atmospheric‐level and elevated concentration (10%) CH4 in a ...

Adaptive Supramolecular Interactions Govern Redox‐Active Molecules in Aqueous Redox Flow Batteries

open access: yesAdvanced Materials, EarlyView.
Adaptive supramolecular interactions overcome the solubility‐stability trade‐off in aqueous redox flow batteries. Hydrophobic anions disrupt intrinsic π–π stacking to enable high solubility, while redox‐state‐dependent spin pairing and cation coordination dynamically stabilize reactive intermediates during operation.

Robotics in Ionizing Radiation Environments: Vulnerabilities, Hardening, and Future Directions

open access: yesAdvanced Robotics Research, EarlyView.
Radiation exposure causes cumulative degradation in robotic sensors, actuators, and electronic logic, often leading to undetected failures. This study maps component vulnerabilities, evaluates hardening and shielding strategies, and identifies testing gaps that must be addressed to enable next‐generation radiation‐tolerant robotic systems.

Unearthing the ecology of soil microorganisms using a high resolution DNA-SIP approach to explore cellulose and xylose metabolism in soil

open access: yesFrontiers in Microbiology, 2016
We explored microbial contributions to decomposition using a sophisticated approach to DNA Stable Isotope Probing (SIP). Our experiment evaluated the dynamics and ecological characteristics of functionally defined microbial groups that metabolize labile ...

A Perspective on the Applications of Triphasic Gas Storage in Electrochemical Systems

open access: yesAdvanced Science, EarlyView.
Gas storage in microporous materials positioned locally at an electrode or electrocatalyst surface enhances electrochemical processes. Abstract Microporous materials store gases under dry conditions (e.g., hydrogen or oxygen via physisorption), but in some cases microporous materials also show triphasic (e.g., in a solid|gas|liquid system) gas storage ...

Dead bacterial biomass-assimilating bacterial populations in compost revealed by high-sensitivity stable isotope probing

open access: yesEnvironment International, 2019
Pathogens are known to survive in compost and to regrow under the influence of certain factors, such as moisture content, temperature and nutrient availability. Dead biomass, by providing available nutrients, is a factor that may affect pathogen regrowth.

Near‐Unity Selectivity Inversion Between CO2 Electroreduction and H2 Evolution via Atomic Coordination Editing

open access: yesAdvanced Science, EarlyView.
Atomic coordination editing functions as an on/off switch that toggles single‐atom catalysts between CO2 electroreduction and hydrogen evolution. ABSTRACT Precise atomic coordination editing of single‐atom catalysts (SACs) provides an effective strategy to tune their electronic structures and catalytic selectivity. Yet, achieving near‐unity selectivity
