Optical Emission Spectroscopic Investigation of CN-Related Emission Behavior and C-N-O Coupling in CO₂/N₂ Plasmas

Applied Sciences
Optical emission spectroscopy was used to investigate CN-related emission in atmospheric-pressure microsecond-pulsed spark discharges of pure N2, pure CO2, and CO2/N2 mixtures. This study examines how gas composition and pulse repetition frequency affect

Structural and biochemical analysis of a B12 superbinder

FEBS Letters, EarlyView.
BtuG proteins are vitamin B12 scavengers in Bacteroides thetaiotaomicron, a dominant human gut bacterium. We present crystal structures of three BtuG homologs bound to cobalamin and its precursor cobinamide, revealing picomolar binding affinities, among the highest known for any natural protein.

Selective C−C Coupling by Spatially Confined Dimeric Metal Centers

iScience, 2020
Summary: Direct conversion of carbon dioxide (CO2) to high-energy fuels and high-value chemicals is a fascinating sustainable strategy. For most of the current electrocatalysts for CO2 reduction, however, multi-carbon products are inhibited by large ...

Comparative assessment of crystallographic and cryo‐EM models in the Protein Data Bank

FEBS Open Bio, EarlyView.
Raw data obtained by X‐ray crystallography or cryo‐EM result in experimental maps, ultimately fitted by atomic models. Although the physical principles are different, the final results can be viewed, compared, and evaluated in the same way. With cryogenic electron microscopy (cryo‐EM) on track to surpass X‐ray crystallography as the preferred method ...

Gas-Sensing Performance of Gadolinium Ferrates with Rod and Butterfly Morphologies

Chemosensors, 2023
There is an urgent need to develop a low-cost and high-performance gas sensor for industrial production and daily life. Perovskite-type oxides are appropriate materials for resistive gas sensors.

Thermomechanical Fatigue and Creep–Fatigue Interaction of Inconel 718 Additively Manufactured by Laser Beam Powder Bed Fusion

Advanced Engineering Materials, EarlyView.
Thermomechanical fatigue tests of laser beam powder bed fusion (PBF‐LB) Inconel 718 show that the additively manufactured material reaches almost the lifetimes of conventionally‐rolled material under no‐dwell conditions. Introducing dwell times at the maximum temperature markedly reduces the lifetimes due to pronounced grain boundary sliding associated

Strain softened bending modulus of graphene oxide

Carbon Trends, 2022
Graphene oxide is attractive in flexible materials due to its biocompatibility. Herein, flexibility of graphene oxide under uniaxial tensile strain has been studied in term of the bending modulus. It is demonstrated that tensile strain plays an effective

Electron-beam spectroscopy for nanophotonics [PDF]

Nature Materials, 2019
Progress in electron-beam spectroscopies has recently enabled the study of optical excitations with combined space, energy and time resolution in the nanometer, millielectronvolt and femtosecond domain, thus providing unique access into nanophotonic structures and their detailed optical responses.

Towards Defect Phase Diagrams: From Research Data Management to Automated Workflows

Advanced Engineering Materials, EarlyView.
A research data management infrastructure is presented for the systematic integration of heterogeneous experimental and simulation data required for defect phase diagrams. The approach combines openBIS with a companion application for large‐object storage, automated metadata extraction, provenance tracking and federated data access, thereby supporting ...
