1‐Azabicyclo[1.1.0]butanes (ABBs) on the Map: Mechanistic Pathways for Catalytic Ring Opening and Functionalizations

Angewandte Chemie, EarlyView.
Catalytic strain‐release ring opening and functionalizations of 1‐azabicyclo[1.1.0]butanes (ABBs) represent a promising strategy for accessing diverse azetidine products. These transformations proceed via polar pathways, radical pathways, and hybrid mechanisms that combine both.

Dual Element (C/Cl) Isotope Analysis Indicates Distinct Mechanisms of Reductive Dehalogenation of Chlorinated Ethenes and Dichloroethane in Dehalococcoides mccartyi Strain BTF08 With Defined Reductive Dehalogenase Inventories

Frontiers in Microbiology, 2020
Dehalococcoides mccartyi strain BTF08 has the unique property to couple complete dechlorination of tetrachloroethene and 1,2-dichloroethane to ethene with growth by using the halogenated compounds as terminal electron acceptor. The genome of strain BTF08

Gate Metal‐Driven Sensing and Memory Bifunctionality in Intrinsically Stretchable Organic Electrochemical Transistors for Soft Neuromorphic Systems

Advanced Science, EarlyView.
Intrinsically stretchable OECTs enable bifunctional operations via gate engineering. Polarizable Ag/AgCl gates provide volatile sensing, while Au gates enable non‐volatile memory. The SEBS‐blended channel maintains performance under strain, supporting reliable signal transduction.

Active Metal Template Synthesis of Rotaxanes From BINOL‐Phosphate Macrocycles

Angewandte Chemie, EarlyView.
The use of macrocyclic BINOL‐phosphates allows for the active metal template synthesis of [2]rotaxanes via Cu(I)‐mediated alkyne‐azide cycloaddition. DFT calculations, control experiments, and kinetic experiments support a dinuclear phosphate‐Cu2 intermediate.

Chlorine Isotope Effects from Isotope Ratio Mass Spectrometry Suggest Intramolecular C-Cl Bond Competition in Trichloroethene (TCE) Reductive Dehalogenation

Molecules, 2014
Chlorinated ethenes are prevalent groundwater contaminants. To better constrain (bio)chemical reaction mechanisms of reductive dechlorination, the position-specificity of reductive trichloroethene (TCE) dehalogenation was investigated.

Controlled Atom Transfer Radical Depolymerization

Advanced Science, EarlyView.
Controlled atom transfer radical depolymerization allows for precise, uniform shortening of polymer chains to yield monomers on demand. By tuning catalyst concentration and temperature, this strategy prioritizes deactivation to maintain molecular weight control throughout depolymerization.

Development of Versatile Nanoparticle System for Efficient Drug Delivery into Pulmonary Endothelium

Advanced Science, EarlyView.
Pediatric acute respiratory distress syndrome (PARDS) suppresses the FOXF1 transcription factor and disrupts lung development. This study shows that the FOXF1‐activating small‐molecule compound, TanFe[F], can be precisely delivered to lung endothelial cells using the innovative LEDD nanoparticle system.

Effect of chlorinated ethene conversion on viability and activity of Methylosinus trichosporium OB3b [PDF]

, 1997
The effect of transformation of chlorinated ethenes on the cell viability of Methylosinus trichosporium OB3b was investigated. A comparison of the loss of viability with the decrease in transformation rates shelved that for the monooxygenase-mediated ...
