Slowing Down Water: Enhanced and Cation‐responsive MRI Contrast

Angewandte Chemie, Volume 138, Issue 29, 13 July 2026.
The controlled modification of mesoporous silica nanoparticle side walls with kosmotropic motifs supports an ability to reduce water diffusive mobility and dramatically increase MRI contrast to levels unprecedented for highly kinetically stable Gd‐DOTA configurations (both q = 1 and q = 0).

Isolation of a Highly Reactive CBNC Heterocumulene via Azidoborylene Photolysis: Facile Access to a Crystalline Dioxaborirane

Angewandte Chemie, Volume 138, Issue 29, 13 July 2026.
Azidoborylene photolysis results in the isolation of a reactive C═B═N═C heterocumulene bearing an ambiphilic boron centre. Addition of 3O2 to this species results in the clean conversion to a unique example of a dioxaborirane. ABSTRACT Oxidation of the formal boron(0) complex MeCAAC2B in the presence of tetrabutylammonium azide leads to the formation ...

Engineered Bacterial Membranes as Next‐Generation Platforms for Cancer Immunotherapy

Small Science, Volume 6, Issue 8, August 2026.
Engineered bacterial membrane platforms, including outer membrane vesicles, bacterial ghosts, genetically engineered membranes, and hybrid bacterial–tumor membranes, integrate tumor antigen presentation with intrinsic immune stimulation. These platforms promote dendritic‐cell activation, T‐cell priming, pyroptosis, and synergistic responses with ...

Metal‐Free, Mild, and Sustainable Synthesis of Bio‐Based Polyesters via EDC/DMAP‐Mediated Polycondensation: Structure–Property Relationships and Thermal Stability

ChemSusChem, Volume 19, Issue 14, 29 July 2026.
We developed a mild, metal‐free EDC/DMAP‐mediated polycondensation platform for bio‐based polyesters from FDCA (2,5‐furandicarboxylic acid) and succinic acid, enabling access to homopolyesters from unsaturated and aliphatic diols as well as heteropolyesters prepared by one‐pot or sequential routes.

Harnessing Random Polymers as Chemoselective Catalysts With Structural Adaptability: Epoxidation of Olefinic Quaternary Ammonium Salts via Charge Recognition

Chemistry – A European Journal, Volume 32, Issue 27, 17 July 2026.
The development of chemoselective catalysts that operate across structurally diverse substrates remains a long‐standing challenge. Here, we demonstrate that a random heteropolymer bearing carboxylic acid and urea residues functions as a general epoxidation catalyst for olefinic quaternary ammonium salts.
