Metal-air batteries have achieved great proceedings in the past decade. This review summarizes progresses of cathode evolution and anode protection strategies in the area of Li/Na-air batteries and prototypes of flexible batteries are presented. More details are discussed in the article by Zhang et al. on page 32—42.

Chiral structure is very common in nature. especially, the chiral materials could rotate the polarized light. Light-matter interaction is very important for process of nature. Inorganic nanomaterials with unique chiral configuration and suitable size have shown exquisitely chiral recognition and selective catalysis function, similar to natural restriction endonuclease. There are no unbridgeable gulf between organic molecules and inorganic materials. The physical and chemical mechanisms involved in chiral phenomenon are very helpful to exploit novel application of chiral materials in biological sensing, imaging, gene editing and information communications. More details are discussed in the article by Kuang et al. on page 25—31.

Bioluminescence is an amazing natural phenomenon and has been applied broadly. We have been devoting to the mechanistic investigation of bioluminescence. Here theoretical study on firefly bioluminescence was systematically introduced.

A copper-catalyzed enantioselective arylcyanation of styrenes was developed with the readily available anilines as aryl radical precursors under mild conditions, which allows the access of chiral 2,3-diaryl propionitriles with moderate to good enantioselectivities. This reaction exhibits broad substrate scope and functional group tolerance.

A catalytic asymmetric syn-selective vinylogous Mannich-type reaction is developed based on copper(I)-Et₃N-catalyzed facile dienolization of α,β-unsaturated pyrazoleamides. By using β,γ-unsaturated pyrazoleamide, α,β-unsaturated pyrazoleamide, (R)-DTBM-SEGPHOS, and (S)-DTBM- SEGPHOS, all four isomers of both the vinylogous product and a chiral 2,3-disubstituted piperidine are synthesized efficiently.

We developed an environmentally benign protocol for α-bromination of furan-2-carboxylates with LiBr and K₂S₂O₈ in good yields. The resulting 5-bromofuran-2-carboxylates further underwent palladium-catalyzed reductive homocoupling reactions in alcohols using as reductants to afford [2,2’]bifuran-5,5’-dicarboxylic acid esters as the monomers of promising polymer.

The skeleton of (–)-palmyrolide A is disassembled into five structural modules, each of which possesses two orthogonal functional groups and is ready for modular assembling reactions. Four of the five modules are commercial reagents, enabling concise synthesis of the target molecule.

For diamondback moth, 8m exhibited better activity than Chlorantraniliprole at a hundred fold preference. The calcium imaging technique experiment results suggested that compound 8m could increase the intracellular [Ca²⁺]_i and further experiments confirmed that the target of this series of compounds could be RyRs in the central larvae neurons of oriental armyworm.

Wide-range photoluminescence modulation of an Ag₁₄ nanocluster was achieved by site-specific surface modification with a variety of fluorescent pyridyl ligands.

The structures of C₆₀ dimer and its nitrogen doping species (C₅₉N)₂ are discussed in detail, and the differences between computational and experimental geometrics are described.

Four ruthenium(II) complexes 1—4 [RN=CH-(2,4-(^tBu)₂C₆H₂O)]RuH(PPh₃)₂(CO) (R = C₆H₅, 1; R = 4-MeC₆H₄, 2; R = 4-ClC₆H₄, 3; R = 4-BrC₆H₄, 4) bearing Schiff base ligands were successfully synthesized. Their structures were fully characterized by elemental analysis, IR, NMR spectroscopy and X-ray crystallography. These Ru(II) complexes exhibit high catalytic performance and good functional-group compatibility in the acceptorless dehydrogenation of secondary alcohols, affording the corresponding ketones in 82%—94% yields.

A concise, protecting-group free total synthesis of a putative natural spirooxindole alkaloid, cabucine oxindole A (1) is described. Biological investigation of 1 and its synthetic intermediates revealed that lactone 2 has mild inhibitory activity against MOLT-4 and MCF7 cell lines.

Cationic rare-earth aryloxide complexes based on tridentate NNP ligands are prepared and applied for RE/P Lewis pair polymerization of methyl methacrylate, which afford isotactic polymers when using ligands with substituent on the pendant arm.

A combined method upon galvanostatic intermittent titration technique and electrochemical impedance spectroscopy has been carried out. As a consequence, more diffusion coefficient at more states could be also calculated. Ultimately, the kinetic parameters including the evolution of transport/reaction resistivity as well as the diffusion coefficient could be determined, and whereby the irreversible ability from the electrochemical kinetics could be well understood.

This review focuses on research advances of lithium plating on graphite anode, including the forming mechanisms of Li deposition, corresponding influence factors, detecting methods and hazard of Li plating.

A copper-catalyzed aerobic oxidative ring expansion reaction of isatins with 1,2,3,4-tetrahydroisoquinoline for the synthesis of tetracyclic quinazolinones has been developed.

5-Bromofuran-2-carboxylates were conducted in a palladium-catalyzed reductive homocoupling reactions in the presence of alcohols as the reductant to afford [2,2’]bifuran-5,5’-dicarboxylic acid esters, which are essential monomers of poly(ethylene bifuranoate), serving as an green and versatile alternative polymer for traditional poly(ethylene terephthalate).
