Summary: With the needs of lightweight and sustainable development, the integration of natural fibers through multiscale surface modification has gained attention. Jute fibers (JFs) stand out due to their unique structure, low cost, and good mechanical properties. This study proposes a facile and effective method for preparing ZnO nanorods (NRs) @JFs. The introduced ZnO NRs not only reinforce the fiber, but also provide additional functionalities. The optimized ZnO@JFs show significant improvements in surface energy, tensile strength, elongation at break, thermal stability, and microwave absorption.

Summary: This study presents the design and synthesis of sulfated disaccharide inhibitors based on IdoA(2S)-GlcNS(6S), which showed potent inhibition of Sulf-2. The results suggest that IdoA(2S)-GlcNS(6S) is the shortest fragment size required for effective inhibition of Sulfs, and a trisulfated disaccharide is identified as the minimal fragment size of heparan sulfate for effective endosulfatase inhibition.

Summary: The self-adaptability of galvanostatic electrolysis was found to be helpful in a multistage chemo- and diastereoselective electrochemically promoted cyclodimerization of chalcones. Through a series of reductive events, densely functionalized cyclopentanes with five contiguous stereocenters were obtained (25 examples, yields up to 95%, dr values up to >20:1). Further experimental and electrochemical investigations indicated the crucial role of dynamic kinetic resolution of the aldol intermediate in the reaction mechanism.
