Support‐Controlled Reaction Pathways via Dynamic Sulfur‐Mediated Interfaces for Selective Urea Electrolysis

Advanced Functional Materials, EarlyView.
Sulfur‐doped graphitized carbon nanofibers act as adaptive catalyst–support platforms, enabling dynamic sulfur‐mediated reconstruction and strong metal–support interactions. This unique behavior enhances catalyst stability and controls reaction pathways, achieving highly selective urea oxidation (∼92% N2) coupled with efficient hydrogen evolution ...

Safety operation of chromatography column system with discharging hydrogen radiolytically generated

EPJ Nuclear Sciences & Technologies, 2015
In the extraction chromatography system, accumulation of hydrogen gas in the chromatography column is suspected to lead to fire or explosion. In order to prevent the hazardous accidents, it is necessary to evaluate behaviors of gas radiolytically ...

Isotope effects in gas–liquid chromatography of steroids

Journal of Lipid Research, 1965
When gas–liquid chromatography was performed with steroids containing H3 and C14, the H3/C14 ratio of the effluent was higher at the beginning and at the tail of the steroid peak.

Interstitium‐Mimicking Porous Alveolar Membranes Enable Physiologic Aerosol Transport and Distinct Acute‐Chronic Lung Injury Responses

Advanced Functional Materials, EarlyView.
An interstitium‐mimicking membrane combines three‐dimensional alveolar geometry, high pore interconnectivity, and mechanical compliance to overcome transport limitations of conventional lung‐on‐chip barriers. The resulting platform supports physiologic aerosol transport, quantitative analysis of cross‐barrier particle movement, and reveals divergent ...

Motif Editing for Reaction Pathway Switching From Formate to CO in Single‐Atom Indium Catalysts via Adjacent Carbon Site Manipulation

Advanced Functional Materials, EarlyView.
This work presents manipulation of adjacent carbon site in single‐atom indium catalysts via editing In‐N4 motif to In‐N2O2 for reaction pathway switching. Incorporation of O atoms leads to significant electron enrichment on the adjacent carbon sites surrounding the In‐N2O2 motif, which facilitates *COOH adsorption and CO formation with high selectivity.

Fusogenic RNA Nanomodules for Fusion‐Mediated and Multiplexed siRNA Delivery

Advanced Functional Materials, EarlyView.
A fusogenic lipid‐layered RNA nanomodules (L‐CRAMs) enable high‐capacity and long‐lasting siRNA delivery through membrane fusion. These nanomodules carry exceptionally large siRNA payloads, avoid conventional endosomal uptake, and release multiple functional siRNAs through Dicer‐mediated processing.

Halide Perovskite Integrated Photovoltaic Cathodes Incorporating Pt on ZIF‐8‐Derived Carbon for Solar Hydrogen Production

Advanced Functional Materials, EarlyView.
A low‐Pt catalyst supported on zeolitic imidazolate framework (ZIF‐8)‐derived porous carbon and graphite is integrated with a halide perovskite photovoltaic, yielding cathodes that achieve a high photocurrent density (∼20 mA cm−2) under simulated sunlight and exhibit remarkable stability in acidic media over several days, thereby demonstrating a ...
