Summary: To overcome the issues of low specific capacity, high cyclic capacity loss, and poor cycle performance in lithium-sulfur (Li-S) batteries, a heterojunction structure of multiferroic BiFeO3 anchored on hollow spheric TiO2 coated on Celgard separator is proposed. The multiferroic BiFeO3 provides a spontaneous polarization to trap polysulfides, and the hollow spheric TiO2 divides a large surface area for sulfur expansion and improves the conductivity of sulfur and BiFeO3 simultaneously. As a result, the discharge capacity remained at 754 mAh g-1 with coulombic efficiency over 99.2% and 83.7% retention of the initial specific capacity after 800 cycles at 1.0C.

Summary: We proposed a green cyclodepolymerization route for the efficient chemical recycling of poly(ethylene adipate) (PEA) to its cyclic oligomers, cyclic oligo(ethylene adipate)s (COEAs), using dibutyltin oxide as a catalyst and toluene as a solvent. Toluene was found to be a better solvent than chlorobenzene, providing higher yields and easier purification of COEAs from the reaction mixture. The yield of COEAs increased with reduced PEA concentration, prolonged reaction time, and increase of catalyst amount.

Summary: In this study, liquid crystalline binary mixtures of [60]fullerene with a wedge-shaped tris-(alkyl)gallate group were investigated. The phase behavior was determined by the volume fraction of the hydrocarbon moiety, and a transition from a low-temperature lamellar phase to a high-temperature phase was observed. Crystal melting behavior suggested a preference for the longer-chain component to occupy the outer layer of the lamellar phase. The research provides a way to adjust the cross-sectional ratio and tailor the level of cross-sectional mismatch for further soft matter self-assembly modes.

Summary: We demonstrate a bottom-up strategy for achieving helical crystals by chiral amplification in copolyesters through the incorporation of a small amount of (D)-isosorbide. The molecular chirality of isosorbide is transferred to the crystal chirality of poly(ethylene brassylate) and amplified by the formation of right-handed helical crystals. Increasing isosorbide content or reducing crystallization temperature leads to thinner PEB lamellae crystals, enhancing chiral amplification and improving the mechanical properties of aliphatic copolyesters.

Summary: This study addresses two challenges in practical rechargeable aqueous zinc metal batteries (RZMBs), namely the limited utilization of high-loading materials at the cathode and the formation of zinc dendrites at the anode. By using hydrophobic association, the researchers have developed amphiphilic hydrogel electrolytes with unique properties that enable full utilization of high-loading cathode materials and prevent dendrite formation. The use of these electrolytes in Zn||MnO2 batteries has resulted in high areal capacities and the demonstration of large-sized pouch batteries. This work opens up new possibilities for practical RZMBs with large capacities and sizes.
