Abstract ：
Within the family of halide solid electrolytes (SEs), Li2ZrCl6 demonstrates high oxidative stability, cost-effectiveness, and mechanical deformability, positioning it as a promising candidate for SEs. However, the application of Li2ZrCl6 as a SEs was hindered by its low ionic conductivity at room temperature. Current strategies to enhance the ionic conductivity of Li2ZrCl6 primarily are focused on single cation or anion sublattice-engineering, each with distinct advantages and limitations. Here, we propose a novel cation and anion-sublattice-engineering strategy, termed CASE, to increase the amorphous content and thus enhance ionic conductivity. The incorporation of Cu2+ and O2- induces distinctive structural modifications within Li2ZrCl6. This structure corroborated through analytic data of X-ray absorption spectroscopy, the neutron diffraction, and ab initio molecular dynamics. Consequently, the amorphous Li2.1Zr0.95Cu0.05Cl4.4O0.8 achieves an enhanced ionic conductivity of 2.05 mS cm-1 at 25 degrees C. Furthermore, all-solid-state lithium batteries utilizing the amorphous Li2.1Zr0.95Cu0.05Cl4.4O0.8 as an electrolyte and LiNi0.83Co0.11Mn0.06O2 as a cathode exhibit a superior long-term cycling stability retaining 90.3% of capacity after 1000 cycles at 2 C under room temperature, which are much higher than those of Zr-based halide electrolytes in publications. Such a result might stimulate the development of more amorphous structures with high ionic conductivity in the CASE strategy.

Abstract ：
Ultraviolet (UV)-induced damage and limited solar spectrum utilization often hinder the performance of perovskite solar cells (PSCs). Here, a thermally activated delayed fluorescent (TADF) molecule, 4CzIPN, is introduced to address these challenges. Acting as a down-conversion agent, 4CzIPN can convert UV light to visible light via Forster energy transfer, enhancing light absorption and reducing photon loss. Additionally, it can bind Pb2+ defects and prevents organic cation degradation through cationic it-effects, stabilizing the perovskite structure. By serving as a crystal growth site, 4CzIPN can promote intermediate phase formation and delay the crystallization process, and improve film quality while mitigating residual stress due to its high thermal expansion coefficient. Furthermore, its UV filtration and hydrophobic properties would reduce perovskite decomposition and device degradation. These advancements yield a device with a remarkable power conversion efficiency (PCE) of 24.23 % and enhanced optoelectronic properties. The modified device demonstrates outstanding moisture and UV light stability, retaining 90 % of its initial efficiency after 1680 h under ambient conditions (25 +/- 5 degrees C, 15 +/- 5 % RH) without any encapsulation.

Abstract ：
Transition metal dichalcogenides (TMDs) have enormous commercial potential as anode materials for all-solidstate lithium-ion batteries (ASSLIBs). Herein, the copper sulfides (CuS) with a hierarchical nanosphere structure are designed through a facile one-step solvothermal synthetic route. When employed as an anode for ASSLIBs, the CuS hierarchical nanospheres (hn-CuS) exhibited a high capacity of 350 mA h g(-1) after 50 cycles at a current density of 250 mA g(-1) and an outstanding rate capability. The unique three-dimensional (3D) structure of hn-CuS plays an important role in alleviating the volume expansion, thus obtaining excellent electrochemical properties. Moreover, ex-situ X-ray diffraction was used to investigate the possible kinetics and reaction mechanism of the hn-CuS anode. This work inspired a new promise for preparing the other TMDs as anode materials for ASSLIBs with high performance.

Abstract ：
Perovskite solar cells (PSCs) fabricated of TiO2 electron transporting material (ETM) have aroused tremendous attention, but their power conversion efficiency (PCE) needs further improvements. In this study, for the first time, zirconium (Zr)-doped brookite TiO2 nanorods (ZTO) are synthesized by a facile route and subsequently employed as an ETM in PSCs which finally achieves a considerable PCE of 19.42 % by optimizing all operating conditions. Further characterizations have been undertaken to explore in detail the effects of Zr doping on the nature of the perovskite active layer and the photovoltaic performance. As a consequence, the enhanced PCE can be ascribed to the high quality perovskite crystals and a more favorable energy level alignment between the perovskite layer and ZTO mesoporous layer.

Abstract ：
It is of great difficulty to create a new antimonite with second-harmonic-generation (SHG) intensity larger than 6 times that of KDP. In this study, a polyfluoroantimonite strategy has been proposed to explore fluoroantimonites with large nonlinear optical (NLO) coefficients. Under the cooperation of chemical (highly asymmetric pi-conjugated organic amine) and physical (viscous reaction medium ethylene glycol) methods, two novel polyfluoroantimonites, namely, (3PC)(2)(Sb4F14) and (3AP)(2)(Sb4F13), have been achieved. Interestingly, these two structures contain two new polyfluoroantimonite groups respectively, an isolated (Sb4F14)(2-) four-member polyhedral ring and an infinite [Sb4F13](infinity)(-) helical chain. More importantly, the polar (3AP)(2)(Sb4F13) displays a strong SHG intensity of 8.1 x KDP, a large birefringence of 0.258@546 nm and a high laser-induced damage threshold (LIDT) value of 149.7 MW cm(-2). Theoretical calculations indicated that its strong SHG effect stems from the synergistic effect of the helical [Sb4F13](infinity)(-) polyfluoroantimonite chain and pi-conjugated 3AP(+) cation, with a contribution ratio of 48.93% and 50.77% respectively. This work provides a new approach for the design and synthesis of high-performance fluoroantimonites.

Abstract ：
Spiro-OMeTAD, as a crucial component of hole-transporting layer (HTL), exhibits limited mobility and conductivity, and the lithium bis-trifluoromethanesulfonimide dopant is sensitive to water vapor, which imposes restrictions on the photovoltaic properties of perovskite solar cells (PSCs). Herein, the iron-porphyrin (FePP) is introduced into Spiro-OMeTAD solution as additive, which facilitates the oxidation process of Spiro-OMeTAD, leading to the enhancement of hole mobility and hole extraction and transport. Besides, the surface Pb2+ defects of perovskite film are cured by the presence of carboxylic acids (-COOH) in FePP. As a result, the photovoltaic properties of PSCs with FePP additive have been improved with a power conversion efficiency (PCE) of 21.58%. Moreover, FePP can further anchor Li+ ions in HTL to prevent it from being invaded by water vapor. Dramatically, the degradation of unencapsulated devices with FePP is suppressed significantly, which retains 82.0% of its original PCE under 10-20% relative humidity (RH) after 7100 h and maintains about 79.6% of its original PCE under 50-60% RH after 1000 h. Thus, this study shows that the design and development of multifunctional HTL additives holds great potential for achieving highly efficient and durable PSCs. The iron-porphyrin additive can not only promote the oxidation of Spiro-OMeTAD and improve the extraction and transport of holes of HTL, but also passivate the Pb2+ defects of perovskite film and prevent the Li+ from being invaded by water vapor, which enhance the power conversion efficiency and stability of perovskite solar cells significantly.image (c) 2024 WILEY-VCH GmbH

Abstract ：
Hydrogen-bonded organic frameworks (HOFs) hold significant promise for catalytic applications. However, the collapse of pores upon solvent removal significantly restricts the utility of HOFs in photocatalytic processes for energy production and storage. This work describes HOF-based catalysis with a stable pore structure and efficient catalytic activity that has been designed and tested for CO2 photo-reduction in pure water. In this system, based on HOFs, the 1,3,6,8-tetra(4-carboxyphenyl)pyrene (H(4)TBAPy) molecules segment the large pore spaces into multiple domains. These molecules, anchored to the HOF via strong CH & ctdot;pi interactions, act as rigid auxiliary linkers, notably improving the structural stability within the HOF. Additionally, the incorporation of electron-rich H(4)TBAPy molecules expedited electron transport within the HOF, markedly enhancing its catalytic activity. This work provides a new strategy for designing stable and high-performance HOF photocatalysts.

Abstract ：
Silicon-based anodes heavily depend on the binder to preserve the unbroken electrode structure. In the present work, natural flaxseed gum (FG) is used as a binder of silicon nanoparticles (SiNPs) anode for the first time. Owing to a large number of polar groups and a rich branched structure, this material not only anchors tightly to the surface of SiNPs through bonding interactions but also formed a hydrogen bonding network structure among molecules. As a result, the FG binder can endow the silicon electrode with stable interfacial adhesion and outstanding mechanical properties. In addition, FG with a high viscosity facilitates the homogeneous dispersion of the electrode components. When FG is used as a binder, the cycling performance of the Si anode is greatly improved. After one hundred cycles at an applied current density of 1 A g-1, the electrode continues to display remarkable electrochemical properties with a significant cyclic capacity (2213 mA h g-1) and initial Coulombic efficiency (ICE) of 89.7%. FG is used as a silicon-based anode binder for lithium-ion batteries for the first time. As FG possesses abundant polar groups and branched chains, it enhances the mechanical properties of the silicon electrode and greatly improves the cycling stability of the silicon electrode. image
