Experimental study on the effect of hydrogen addition on methane/ethylene diffusion flame soot formation based on light extinction measurement

Energy Reports, 2021
In this study, the mixed diffusion flame soot of methane, ethylene and hydrogen were studied, and the two-dimensional light extinction measurement was applied to investigate the distribution characteristics of the ethylene flame soot concentration with ...

Engineering peptides into antibodies—opportunities and strategies for therapeutic innovation

FEBS Letters, EarlyView.
Peptides and antibodies occupy complementary therapeutic niches. Peptides recognize difficult targets in a compact format, while antibodies add specificity, long half‐life, and effector functions. This review examines strategies that merge both modalities—peptide grafting into loops, terminal and Fc fusions, and bioconjugation—highlighting how ...

Study of NO and CO Formation Pathways in Jet Flames with CH₄/H₂ Fuel Blends

Energies
The existing natural gas transportation pipelines can withstand a hydrogen content of 0 to 50%, but further research is still needed on the pathways of NO and CO production under moderate or intense low oxygen dilution (MILD) combustion within this range

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.

N-Sulfinylpyrrolidine-containing ureas and thioureas as bifunctional organocatalysts

Beilstein Journal of Organic Chemistry, 2021
The synthesis of bifunctional N-sulfinylureas and thioureas with an appended pyrrolidine unit is presented. These organocatalysts were evaluated in Michael additions of aldehydes to nitroalkenes both under solvent-free conditions and in solution.
