Chirality Transfer in Coassembled Organogels Enabling Wide-Range Naked-Eye Enantiodifferentiation

Enantiodifferentiation is crucial in organic chemistry, pharmacochemistry, material chemistry, and life science. However, it remains tremendously challenging to achieve a broad enantioselectivity to different types of chiral substrates via a single-material design. Here, we report a coassembled organogel strategy with chirality transfer to make an enantioselective generality possible. This…

Preparation and liquid crystal phase properties of discotic cellulose nanoparticles

Li, Chenxi; Evans, Julian; Wang, Nan; Guo, Tingbiao; He, Sailing

Understanding the behavior of fluids with inhomogeneous structural properties is critical for many industrial and biological materials. Sulfuric acid hydrolysis of cotton with ultrasonic treatment and low-speed centrifugation during purification yields “spiky” discotic cellulose particles. Amorphous cellulose remained in solution and forms discotic units which may be nucleated by crystalline…

Towards mechanical robust yet self-healing polyurethane elastomers via combination of dynamic main chain and dangling quadruple hydrogen bonds

Hu, Jin; Mo, Ruibin; Jiang, Xiang; Sheng, Xinxin; Zhang, Xinya

One of the greatest challenges of robust self-healing materials is the confliction between high chain mobility for self-healing and a stable structure for mechanical strength. Herein, dangling 2-ureido-4-pyrimidione (UPy)-functionalized side groups were introduced into the hard segments of thermoplastic polyurethane (TPU) elastomers, where embedded the dynamic disulfide bonds in the…

Aescin-Induced Conversion of Gel-Phase Lipid Membranes into Bicelle-like Lipid Nanoparticles

Geisler, Ramsia; Pedersen, Martin Cramer; Hannappel, Yvonne; Schweins, Ralf; Prévost, Sylvain; Dattani, Rajeev; Arleth, Lise; Hellweg, Thomas

Mixtures of the phospholipid 1,2-dimyristoyl-sn-glycero-3-phosphocholine (DMPC) and the saponin ?-aescin spontaneously form monodisperse, bilayered discoidal micelles (also known as “bicelles” or “nanodisks”) in aqueous solution. Such bicelles form below the melting temperature of DMPC when the phospholipids are in the rigid L?? state and are precursors of spontaneously formed vesicles.…
