Germanane Quantum Dots Promote Metabolic Reprogramming of Immune Cells Toward Regulatory T Cells and Suppress Inflammation In Vitro and In Vivo

Advanced Functional Materials, EarlyView.
Metabolic changes in immune cells direct the phenotype and function of the host immune system. Smart nanomaterials must target metabolic pathways to direct immune cell fate. This study reports the fabrication and first application of germanane quantum dots (GeHQDs) to modulate inflammation in vitro and in vivo.

Robust bifunctional aluminium–salen catalysts for the preparation of cyclic carbonates from carbon dioxide and epoxides

Beilstein Journal of Organic Chemistry, 2015
Two new one-component aluminium-based catalysts for the reaction between epoxides and carbon dioxide have been prepared. The catalysts are composed of aluminium–salen chloride complexes with trialkylammonium groups directly attached to the aromatic rings

Iminologous Epoxide Ring-Closure

Chemical Science, 2022
Herein, we apply the principle of iminology to the well-established epoxide ring-closure reaction. The synthesis of tetrasubstituted, nitrile-tethered epoxides can be achieved via activation of iminologous diols followed by fragmentation. Mechanistic study reveals the transformation to be stereoretentive, which is consistent with the concerted nature ...
