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 ...

MS and GC–MS Analytical Methods for On-Line Thermally Induced Evolved Gas Analysis (OLTI-EGA)

Chemosensors
Mass spectrometry (MS) and coupled gas chromatography-mass spectrometry (GC-MS) are globally recognized as the primary techniques for the analysis of gases or vapors due to their selectivity, sensitivity, accuracy, and reproducibility.

Harnessing Interfacial Cl− Ions for Concurrent Formate Production at Industrial Level via CO2 Reduction and Methanol Oxidation

Advanced Functional Materials, EarlyView.
The replacement of the anodic OER in CO2RR with energy‐saving methanol oxidation reaction and the creation of a favorable microenvironment through interfacial Cl− ions enable concurrent formate production at industrial‐level current densities. Abstract The efficient electrocatalytic conversion of CO2 to formate is often impeded by the high energy ...

Determination of ifosfamide by gas chromatography—mass spectrometry

Analytica Chimica Acta, 1991
Ifosfamide, an oxazaphosphorine, is thermally stable during elution in gas chromatography (GC) at temperatures above 200 °C, in contrast to its structural isomer cyclophosphamide. Both 2.65-µm and 0.32-µm OV-1 columns were efficient for GC of ifosfamide without derivatization.

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.
