13C‐Labeled Mesoporous N‐Doped Carbon Nanospheres and N‐Doped Hydrothermal Carbon Aerogels as Model Materials for Carbon Corrosion Determination in Electrode Structures

Advanced Energy Materials, EarlyView.
By 13C labeling of carbon support materials used in energy storage and conversion applications, carbon corrosion can be investigated in situ via EC‐MS, giving information about the corrosion rate and whether the carbon support or other carbon‐containing materials in the system are degraded.

Direct Integration of Functionalized Bridges by One‐Step Superacid‐Catalyzed Reaction to Fabricate Porous Polymers for CO2 Capture and Separation

Angewandte Chemie, EarlyView.
The one‐step polymerization of unfunctionalized polyaromatic monomers and glyoxylic acid under superacid‐catalysis conditions promotes the simultaneous generation of highly porous 3D architectures and the controlled decoration of pore surfaces with aliphatic carboxylic acids. These ultra‐microporous frameworks and their ester and polyionic derivatives,

Cryogenic liquid-jet breakup in two-fluid atomizers [PDF]

A two-fluid atomizer was used to study the breakup of liquid-nitrogen jets in nitrogen, argon, and helium atomizing gas flows. A scattered-light scanner particle sizing instrument previously developed at NASA Lewis Research Center was further developed ...

Selective Electrochemical Reduction of CO2 to Metal Oxalates in Nonaqueous Solutions Using Trace Metal Pb on Carbon Supports Enhanced by a Tailored Microenvironment

Advanced Energy Materials, EarlyView.
Encapsulating trace lead (Pb) in carbon electrodes with a fluoropolymer tailors the microenvironment for carbon dioxide (CO2) reduction. This enhances efficiency and selectivity, offering a tunable approach to guide reaction pathways and improve product outcomes in electrochemical CO2 conversion.

In Situ/Operando Probing of Dynamic Phase Structures of Alumina‐Supported Ultrasmall Copper‐Gold Alloy Nanoparticles Under Reaction Conditions

Angewandte Chemie, EarlyView.
Supported ultrasmall copper‐gold alloy nanoparticles are active heterogenous catalysts. In situ TEM tracking under oxygen at different temperatures reveals atomic‐scale dynamic phase structures, whereas combined operando synchrotron HE‐XRD and DRIFTS characterizations uncover ensemble‐averaged ordering/disordering phase structures and oscillatory ...

Enhanced and Durable Light‐Driven Hydrogen Evolution by Cobalt‐Based Prussian Blue Analogs in Phospholipid Bilayers

Advanced Energy and Sustainability Research, EarlyView.
Light‐driven H2 evolution catalysis is reported for oleylamine‐capped MCo Prussian blue analogs (PBAs, M = Ni, Co, Zn, Cu) within phospholipid bilayers and using a ruthenium‐based amphiphilic photosensitizer. The hydrophobic interactions between the active units bring them in close proximity facilitating catalysis.
