Advanced Science, EarlyView.A well‐designed experimental model reveals a trade‐off between intrinsic activity and catalytic site density in performance optimization, due to inherent diffusion resistance arising from substrate adsorption at catalytic sites. Abstract Enhancing intrinsic activity and increasing catalytic site density are two widely employed strategies to improve ...

Angewandte Chemie, EarlyView.A dimethylsulfoniopropionate lyase (DddK) was identified as an efficient aza‐Michaelase for the addition of amines to acrylate. Screening 74 amines with wild‐type DddK and its W26G variant yielded N‐substituted and N,N‐disubstituted β‐amino acids in 30%–93% isolated yield.

Abrupt and Reversible Stretching in an Azobenzene Single Crystal via Thermal Phase Transition
Advanced Science, EarlyView.Crystals of azobenzene compounds exhibit abrupt and reversible stretching and shrinking in response to thermal and photo stimulation. The single‐crystal‐to‐single‐crystal phase transition between two polymorphs involving reorientation of CH–π hydrogen interactions are demonstrated. Furthermore, the abrupt photoinduced stretching of the crystals is used

RNA G‐Quadruplex RIBOTAC‐Mediated Targeted Degradation of lncRNA TERRA
Advanced Science, EarlyView.This study introduces a selective RNA degradation strategy targeting long noncoding RNA (lncRNA) TERRA, upregulated in ALT (alternative lengthening of telomeres) cancer cells. Using ribonuclease‐targeting chimeras (RIBOTACs), RNase L is recruited to catalytically degrade TERRA, uncovering a novel approach to affect a disease associated lncRNA in ALT ...

Driving Multi‐Step Regioselectivity in On‐Surface Polymer Synthesis by Molecular Coverage
Angewandte Chemie, EarlyView.Regioselective polymerization of dicyclopentaanthracene on Au(111) can be controlled by tuning molecular coverage. Low coverage yields 1D polymers, medium coverage produces quasi‐1D staircase polymers, and higher coverage drives 2D porous networks.

Advanced Energy and Sustainability Research, EarlyView.Considerable improvement in the performance of fully‐hydrocarbon‐based fuel cells is necessary to replace and compete with Per‐ and polyfluoroalkyl substances‐containing fuel cells. Herein, a way to enhance the ionic conductivity of the catalyst layer (CL) by incorporating insoluble ionomer particles into the CL is presented.

Aggregate, EarlyView.A multifunctional nanoplatform (USiCeCurAu) integrating UCNPs, AuNPs, CeO2, and TK‐CUR‐TPP enables synergistic PDT, CDT, and mPTT. The AuNPs act as pore lockers, UCNPs convert NIR into UV/Vis emission, which triggers AuNPs aggregation, TPP‐CUR‐mediated mitochondria damage for HSP70 suppression, and CeO2‐enabled dual role in ROS generation and ...
