The Far Side of Carboranes: Anticancer Active Monocations and Ambiently Stable Dications
Angewandte Chemie, EarlyView.This work describes the synthesis of bench‐stable dicationic carboranes. Their enhanced electrophilicity is documented by opening the clusters with weak nucleophiles or dihydrogen. The surprising stability of positively charged carboranes in water enabled a study of their in vitro antiproliferative activity, which surpassed the effects of doxorubicin ...

Small‐Molecule Activation of mRNA Translation by Click‐to‐Release Reaction in Cells
Angewandte Chemie, EarlyView.A new method to control mRNA activity using bioorthogonal click‐to‐release reactions is presented. The 5′ cap is modified with a trans‐cyclooctene (TCO) that quickly reacts with hydroxyaryl‐tetrazines and efficiently releases the native cap 0. TCO‐capped mRNAs are initially translationally inactive but can be activated with non‐toxic, cell‐permeable ...

Advanced Engineering Materials, EarlyView.Copper‐based composites enhanced with carbon feature convenient mechanical properties and favorable electric conductivity. Processing via deformation and thermomechanical treatments can introduce advantageous microstructures further enhancing their performance. Herein, copper–graphene powder‐based composites are directly consolidated via rotary swaging

Advanced Functional Materials, EarlyView.AgCrP2S6 reveals a momentum‐indirect band edge (≈1.35 eV) and chain‐locked linear dichroism: the first direct transitions emerge at 1.6–1.8 eV for E||a. Resonant Raman and photoemission corroborate this assignment. In ACPS/graphene heterostructures, photocurrent turns on above ≈1.5 eV and follows the same polarization selection rules (anisotropy ≈0.53),

Liquid Metal Microrobots for Magnetically Guided Transvascular Navigation
Advanced Materials, EarlyView.Liquid metal‐based microrobots combine magnetic steering, intrinsic X‐ray visibility and softness, to navigate blood vessels even against flow. Under clinically relevant magnetic fields, liquid metal microrobots roll along vessel walls, cross endothelial barriers, and accumulate in target tissues.
