Identification of arachidonate epoxides/diols by capillary chromatography-mass spectrometry.

Journal of Lipid Research, 1995
The identification of epoxide regioisomers of arachidonic acid (EETs) as methyl esters is difficult because they coelute during gas chromatography and possess similar mass spectra.

Copper Doping Enhances the Activity and Selectivity of Atomically Precise Ag44 Nanoclusters for Photocatalytic CO2 Reduction

Advanced Functional Materials, EarlyView.
By a simple anti‐Galvanic reaction, up to six copper atoms could be preferably doped into the Ag2(SR)5 staple motifs and Ag20 dodecahedral shell of an atomically precise Ag44(SR)30 nanocluster. When anatase TiO2 is used as substrate, the (AgCu)44/TiO2 photocatalyst exhibited much improved activity in photocatalytic CO2 reduction compared to Ag44/TiO2 ...

Adalimumab‐Poloxamer Conjugate for Bio‐Better: Enhanced Stability and Function

Advanced Functional Materials, EarlyView.
Antibody‐polymer conjugates, particularly poloxamer conjugates, enhance antibody stability by improving tolerance to physicochemical stress and attenuating proteolysis by proteases. Furthermore, the higher affinity observed with poloxamer conjugation compared to standard PEGylation results in improved therapeutic efficacy in rheumatoid arthritis mouse ...

Rotating Liquid Marble Microreactors for Enhanced Enzymatic Reactions

Advanced Functional Materials, EarlyView.
Dynamic magnetic liquid marbles (LMs), stabilized by hydrophobic magnetic proteinaceous colloidosomes, function as effective microreactors for enzymatic processes. Precise magnetic manipulation allows for the rotation of these LMs, enhancing the efficiency of the enzymatic cascade reaction both at the air/water interface and within biphasic enzyme ...

Controlled Aggregation of Pyrene‐Based Supramolecular Nanostructures for Light‐Driven Switchable H2 or H2O2 Production

Advanced Functional Materials, EarlyView.
This work reports the self‐assembly of a pyrene derivative into two distinct nanostructures and their application in visible‐light photocatalysis. The two nanostructures exhibit completely different yet complementary photocatalytic activities, promoting either H2 or H2O2 evolution.
