Summary: Croconic acid, a highly electron-deficient building block, was used to create a conjugated microporous polymer (CTPA). The CTPA possessed strong donor-acceptor interactions, resulting in near-IR absorption, a narrow bandgap, and high electrical conductivity upon doping. Compared to its squaric acid counterpart (STPA), CTPA exhibited superior optical, electronic, and electrical properties.

Summary: Polymer membranes usually have a wide pore-size distribution, resulting in lower selectivity in ion separation compared to membranes made of crystalline porous materials. However, ion-sieving membranes based on conjugated microporous polymers with high uniform sub-nanometer pores can achieve high ion-separating performance with a sub-1 A size precision, attributed to their uniform and narrow pore-size distribution.

Summary: This study demonstrates the use of a solution-processable conjugated microporous thermoset (CMT) as an ultrathin ion sieving layer to overcome the issues of polysulfides shuttling and lithium dendrite growth in lithium-sulfur (Li-S) batteries. The CMT layer effectively blocks the shuttling of polysulfides while allowing the passage of Li ions, and it also acts as a buffer zone for uniform distribution of Li ions on the anode surface, resulting in high capacity, low attenuation rate, and long cycling lifespan.

Summary: The atomistic structural engineering of donor-acceptor polymer photocatalysts enhances charge separation and photocatalytic hydrogen production. Changing the electron affinity of the acceptor units allows for tuning of electron delocalization and exciton binding energy, resulting in improved efficiency. The optimized sample exhibits the highest H-2 production rate of 3207 mu mol g(-1) h(-1) when ascorbic acid is used as the sacrificial agent. Additionally, photocatalytic H-2 production can be coupled with near stoichiometric conversion of 5-hydroxymethyl furfural to 2,5-diformylfuran.

Summary: This study analyzes the Silurian volcanic rocks in the Wanbaogou area of the southern Kunlun Orogen to reveal the tectonic setting of this region during the middle to late Silurian. The volcanic rocks are divided into trachytic and basaltic groups, formed during the middle to late Silurian. The basalts show characteristics of within-plate volcanic rocks with high Nb/La ratios, while the trachytes likely formed through the melting of young basaltic crust. These findings are significant for understanding the tectonic evolution of the middle-late Silurian in the Kunlun Orogen.

Summary: S and O elements doped g-C3N4 nanosheets samples were prepared by calcinating the supramolecular precursor obtained through self-assembly of melamine and cyanuric acid using one-step double crucible method. Doping narrows the layer spacing of g-C3N4 in the O/S single-element doped sample, but in the S, O co-doped sample, this phenomenon disappears due to the compensation effect of S and O atoms in adjacent layers. The S, O co-doped g-C3N4 sample shows the best photocatalytic performance as the 3d orbitals of S atoms act as both donor and acceptor levels, contributing to the separation of photogenerated electrons and holes.

Summary: Developing dopant-free carrier-selective contacts for c-Si solar cells has attracted attention in recent years. In this study, a perovskite material, ZnTiO3, combined with an ultrathin SiO2 film and Al layer, is used as an electron-selective contact. Postmetallization annealing at 200-350 degrees C improves the efficiency of the perovskite/c-Si heterojunction solar cells by 3.5%. The annealing treatment leads to Al diffusion into the ZnTiO3 film, doping the film and reducing its work function, as well as improving the coverage of SiO2.

Summary: Due to the intrinsic defects in perovskite films, which cause undesired carrier recombination, the power conversion efficiency of perovskite solar cells is seriously affected. To eliminate these defects, a multifunctional Taurine molecule was introduced into the perovskite precursor solution. It was found that Taurine can bind with uncoordinated Pb2+ and I- ions and significantly reduce the defect density and suppress carrier recombination. PSCs with Taurine showed a higher power conversion efficiency of 13.19% compared to the control device (11.26%), and also demonstrated enhanced stability.
