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.

Engineering an Artificial Metalloenzyme for Efficient Photo‐Enzymatic CO2 Conversion

Advanced Science, EarlyView.
We built a light‐driven artificial metalloenzyme by covalently conjugating formate dehydrogenase (FDH) with a tailored rhodium complex (Rh‐L6) to overcome spatial‐separation‐limited electron transfer. This integration boosts NADH regeneration and CO2 conversion, giving 2.31‐fold higher formate yield than physical mixtures, due to a narrowed bandgap and

Precision Matters: Minor Concentration Deviations of DMSO May Cause Major Efficacy Shifts

Angewandte Chemie, EarlyView.
Low‐concentration dimethyl sulfoxide (DMSO) has long been regarded as biologically safe in drug discovery. However, increasing DMSO from 0.1% to 0.9% reduces photosensitizer PNA‐9 particle size from 657 nm to 260 nm, enhancing endocytosis and photodynamic therapy outcomes.

Photocatalytic degradation of photosensitizing and non-photosensitizing dyes over chromium doped titania photocatalysts under visible light

, 2017
A series of 0.5–4 mol% Cr-doped TiO2 photocatalysts were tested over photocatalytic degradation of photosensitizing (Methylene Blue) and non-photosensitizing (Congo Red) dyes under visible light irradiation.
