Herein, a single molecule detection technology based on glass nanopore is established to analyze xylan dissolved in ionic liquid. The nanopore detection technology shows the structural difference of heterogenous branched chain and homogeneous straight chain based on the single characteristic current blocking signal and statistical information, providing a research basis for the structural analysis of water insoluble polysaccharides. More details are discussed in the article by He et al. on page 1720—1726.

According to the existing forms of rare earth elements, we classify rare earth promoted transition metal sulfides into rare earth doped transition metal sulfides, rare earth interface promoted transition metal sulfides, and rare earth structure promoted transition metal sulfides. We also prospect their applications in OER, HER, ORR, and CO₂RR, as well as in other electrocatalytic fields. In today's increasingly serious energy problem, it is of great significance to rationally utilize rare earths to promote the regulation of transition metals, enabling them to achieve more efficient and stable energy storage and conversion. More details are given in the article by Xi et al. on page 1740—1752.

We herein report the synthesis and structures of a heteroarene-azo functionalized photoswitchable 19-nuclei Mn cluster. This cluster shows quick trans-to-cis transformation and magnetic change.

A nickel/photo-cocatalyzed and chiral Quinim ligand promoted asymmetric carbamoyl-acylation of unactivated alkenes tethered to carbamoyl chloride with various aldehydes is reported here. The reaction is featured by broad substrate scope with high enantioselectivity, providing diverse valuable γ-lactam products carrying an acyl transformable functionality. The success application of Quinim ligand in this reaction demonstrates more applicable possibilities in other catalytic asymmetric transformations.

Skeletal Reorganisation of Cyclobutanones: We for the first time demonstrates that Pd-catalyst is also capable of cleaving C(carbonyl)−C bonds of cyclobutanones via oxidative addition. According to Pd-catalyzed condition, the skeletal reorganization of cyclobutanones involving successive cleavage of C(carbonyl)−C bonds and C—H bond cleavage proceeds smoothly to deliver diverse indanones.

A strategy to tune polymer molecular weight distribution in cationic polymerization was demonstrated by mixing two cationic RAFT agents with different chain transfer constants. Moreover, the product can be used for both cationic and radical RAFT chain extension.

Zinc dendrites are easily produced on anode surface during the cycling of zinc-based batteries. The introduction of TU-CQDs in alkaline electrolyte can uniform the zinc deposits and improve the reversibility of zinc plating/stripping processes.

Nucleophilic substitution reaction and 1,3-dicarbonyl compounds have become an emerging research area in organic chemistry. Here, we demonstrate the successful nucleophilic substitution polymerization of 1,3-dicarbonyl compounds, where non-traditional intrinsic luminescent poly(1,3-dicarbonyl)s have been successfully prepared with high yield (up to >99%) under mild conditions.

A new kind of hybrid membranes consisting of porous polymer and flexible organic frameworks was developed, which enables ions to flux with high efficiency at the polymer-framework interface, resulting in high osmotic energy harvesting efficiency.

The heterogenous branched chain and the homogeneous straight chain structure can be distinguished from the single characteristic current blocking signal and current blocking statistical information base on nanopore technology.

Metal ions induce the G-quadruplexes hydrogel formation of the conjugation of guanine and peptide epitope.

An unprecedented Pd-catalyzed migration reaction of [60]fullerene with allyloxy-tethered aryl iodides is presented for the preparation of rare [60]fullerene-fused allylbenzofurans. The reaction features high chemo- and regio-selectivity. This transformation proceeds via a sequential C—O bond cleavage/allyl-migration/intermolecular cycloaddition cascade process.

Constructing monolithic tandem solar cells (TSCs) is an effective method to break the Shockley–Queisser (S–Q) radiative efficiency limit for single-junction solar cells. Here, we summarize the current progresses in monolithic perovskite/organic TSCs. The front subcell based on wide bandgap mixed halide perovskites, rear subcell based on low bandgap organic molecules and the interconnection layer (ICL) are discussed, respectively, which aims to open a pathway to realize highly efficient monolithic perovskite/organic tandem device.

This cover picture shows a ligand-controlled, palladium-catalyzed migration reaction of [60]fullerene with allyloxy-tethered aryl iodides. Using 1,2-bis(diphenylphosphino)benzene (DPPBz) as a ligand, the chemoselectivity is switched to synthesize [60]fullerene-fused allylbenzofurans instead of previous spirocyclic derivatives through a sequential C—O bond cleavage/allyl-migration/intermolecular cycloaddition cascade process. Such transformation provides a unique and efficient route to rare [60]fullerene-fused benzofurans. More details are discussed in the article by Liu et al. on page 1733—1739.

This work developed a G-quadruplexes-based hydrogel consisting of guanine and peptide epitope to form a supramolecular hydrogel in the presence of metal cations. Using the metal ion-responsive peptide epitope from the ion channel to replace sugar motif at N⁹ position of guanosine results in a novel nucleopeptide. The results show that the gelation time, the diameter of nanofibers, the anisotropic property, and the mechanical property of the nucleopeptide hydrogel can be simply controlled using metal cations. This work may provide a strategy for gluing pre-existing fibers to form a hydrogel with tailored structures. More details are discussed in the article by Wang et al. on page 1727—1732.
