Summary: The self-assembled behaviors between calixpyridinium and two pyrenesulfonate guests were studied, revealing differences in morphology, properties, and iodine capture capability. PS guests formed spherical aggregates, while PyTS guests formed rodlike aggregates. The calixpyridinium-PyTS aggregates showed strong green fluorescence and had the ability to adsorb iodine in both liquid and vapor phases, whereas the calixpyridinium-PS aggregates could not capture iodine. The diverse capabilities were determined by the self-assembled structure at the molecular level.

Summary: This study presents a spatially compartmentalized artificial organelle for correcting intratumoral metabolite analysis. The organelle consists of a zeolitic imidazolate framework-8 immobilized glucose oxidase-horseradish peroxidase cascade core and catalase-directed shell, which function as signal transduction and guarding rooms, respectively. The core and shell provide appropriate spaces to enhance biocatalytic efficiency and tolerate complex tumor microenvironments. Moreover, catalase decomposes endogenous H2O2 to O-2, overcoming interference in signal output and alleviating hypoxic states, thus maximizing glucose oxidation. The artificial organelle demonstrates great potential for accurate intratumoral metabolite analysis in vitro and in vivo.

Summary: The formation of porous and non-porous polymorphs in different solvents is shown to depend on a solvophobic effect driven by dispersion interactions, with weak dispersion interaction facilitating porous packing. Dense packing is a universal tendency of organic molecules in the solid state, but a solvophobic approach allows for the successful synthesis of porous polymorphs.

Summary: The development of peptide-metal frameworks as proteomimetic materials has been limited by the restricted choice of side chains and few variable residues compatible with metal ions. In this study, a noncovalent strategy using g-stacking bipyridyl residues was developed to assemble longer peptides into crystalline frameworks. These materials exhibited proteomimetic behaviors and could be optimized for increased affinity towards complex organic molecules.

Summary: Compared with solid alkali metal anodes (Li, Na, K), liquid metal anodes (LMAs) have unique advantages such as self-healing property and no dendrites, enabling high-energy batteries. Among LMAs, liquid Na-K alloy anode has received attention due to its high theoretical capacity, low redox potential, and formation at room temperature. However, utilizing liquid Na-K alloy as an electrode is challenging, especially at room temperature with high surface tension. In this study, an amorphous hollow carbon film (AHCF) consisting of hollow spheres with significant surface defects was designed to quickly infiltrate Na-K liquid alloy at room temperature, forming a composite electrode (Na-K@AHCF). The Na-K@AHCF symmetric cell exhibited a cycle lifespan of up to 400 hours at 0.1 mA/cm2 and demonstrated stable stripping/deposition even at 5 mA/cm2. When combined with sulfurized polyacrylonitrile (SPAN) cathode material, the resulting K-S full cell showed good cycle stability and rate performance.

Summary: A phototransistor memory based on air-stable Zr-CsPbI3 perovskite nanocrystals (PNCs) is designed, with broadband photoresponse capability. By utilizing the different electron capture ability of Zr-CsPbI3 PNCs to 650 and 405 nm light, an artificial synapse and non-volatile memory can be created on-demand and quickly reconfigured within a single device for specific purposes. The optically reconfigurable and wavelength-aware operation between short-term plasticity (STP) and long-term plasticity (LTP) modes enables integrated blue feature extraction and target recognition in a homogeneous neuromorphic vision sensor array.

Summary: To address the sluggish oxygen evolution kinetics of bismuth vanadate (BiVO4) photoanodes, a vanadium oxide (VOx) with enriched oxygen vacancies was grown on BiVO4 photoanodes using a photo-assisted electrodeposition process. The optimized BiVO4/VOx photoanode showed a significantly enhanced photocurrent density of 6.29 mA cm(-2) at 1.23 V, which was 385% higher compared to the pristine counterpart. The presence of oxygen vacancies in VOx improved the adsorption of water molecules and promoted charge transfer during the oxygen evolution reaction, resulting in excellent photoelectrochemical (PEC) water splitting performance.

Summary: As a crucial parameter in biochemical analysis, the pH value plays an essential role in cell function, food preservation and production, as well as soil and water sources. Therefore, it is increasingly important to explore pH detection methods. This paper introduces a pH-responsive SERS probe using a cyano Raman tag, which can detect pH values based on the displacement of the cyano Raman peak. The cyano Raman tag exhibits excellent sensitivity within the pH range of 3.0-9.0, with a limit of detection of pH 0.33, and shows anti-interference performance and stability (the relative standard deviation is calculated to be 6.68%, n = 5). These results suggest that this pH SERS probe with the Raman cyano tag could open up new research directions in biological detection, bioimaging, and environmental detection.

Summary: We have successfully achieved photoactivated afterglow emission in a variety of amorphous copolymers through self-doping and polymer rigidification. By regulating the oxygen concentration, the afterglow lifetimes can be increased significantly. Moreover, programmable and reusable afterglow patterns and pulse-width indicators have been established using these stimuli-responsive afterglow polymers. These findings provide a new approach to construct single-component polymeric systems with photoactivated organic afterglow features and demonstrate the superiority of stimuli-responsive materials for remarkable applications.

Summary: This work addresses two key challenges toward fully-sprayed organic solar cells (OSCs): the printing of a high-quality photoactive layer free of coffee rings and the spray of the top electrode without the need of evaporation nor solvents. By depositing the photoactive layer using electrospray on a cooled substrate, coffee rings are eliminated, resulting in homogeneous films and improved performance. A spray-printed alloy electrode with a melting point of 62 degrees C is optimized for coverage and film thickness. The fully-sprayed OSCs achieve a power conversion efficiency (PCE) of 15.09%, showing a viable route towards high-performance fully-sprayed OSCs.

Summary: This study focuses on the enhancement of specific capacity and cycling stability of organic electrode materials (OEMs) for sodium-ion batteries (SIBs) through molecular design. The researchers synthesized a new heteroaromatic molecule (HATN-6OH) with redox-active moieties and conjugated core structures, which exhibited a high specific capacity and stable long-term cycling performance in SIBs. The synergetic coupling of redox-active sites on OEMs could be a key factor in improving the performance of SIBs and other metal-ion batteries.
