Summary: We propose a multiple stream progressive restoration network to enhance and denoise light fields (LFs) under low light conditions. Three types of input are designed to fully utilize the supplementary information and preserve the epipolar information. A multi-stream interaction module is developed to aggregate features from different restoration streams. Multiple stages restoration is introduced to gradually reconstruct the LF.

Summary: Alkali metals (Li, Na, and K) show promise as high-performance rechargeable alkali metal battery anodes due to their high theoretical specific capacity and low electrochemical potential. However, challenges such as high chemical reactivity, uncontrolled dendrite growth, unstable solid electrolyte interphase, and volume expansion during cycling processes hinder their practical application. The introduction of carbon nanotube-based nanomaterials in alkali metal anodes provides a solution to these issues. These nanomaterials with high specific surface area, superior electronic conductivity, and excellent mechanical stability have attracted considerable attention. This review summarizes recent progress on the application of carbon nanotube-based nanomaterials in stable and dendrite-free alkali metal anodes, discusses the merits and issues of alkali metal anodes, as well as their stabilizing strategies, and explores the relationship between synthesis methods, nano- or microstructures, and electrochemical properties of carbon nanotube-based alkali metal anodes. Additionally, advanced characterization technologies on the reaction mechanism of carbon nanotube-based nanomaterials in alkali metal anodes are reviewed. Finally, the challenges and prospects for future study and applications of carbon nanotube-based AMAs in high-performance alkali metal batteries are discussed.

Summary: In this study, a highly active and durable N-CoP/CeO2 nanowire heterostructure electrocatalyst was developed, showing excellent catalytic activity for both oxygen evolution reaction (OER) and hydrogen evolution reaction (HER). The N-CoP/CeO2 catalyst exhibited low overpotentials of 215 and 74 mV at 10 mA cm-2 in 1.0 M KOH. The assembled water electrolyzer with N-CoP/CeO2 displayed super stability, maintaining 95.9% catalytic activity over 42 days at 1.52 V@10 mA cm-2. Theoretical calculations revealed that the metallic heterostructure interfaces of N-CoP/CeO2 enhanced the electrocatalytic activity through fast electron transfer and optimized adsorption/desorption processes.

Summary: The luminescence of non-conjugated polymers is an important subject of research in both fundamental and applied areas. However, the study on nonconventional luminescent polymers (NLPs) in terms of the structure regulation and emission mechanism is still in its early stages. This study reports the efficient NLP property of PA1212, a representative engineering plastic, which exhibits blue fluorescence, persistent room-temperature green phosphorescence, and high quantum yield (about 13%). The research demonstrates the crucial role of hydrogen-bonded amide groups in the emission and reveals the linear positive correlation between emission intensity and amide clusters constructed from ordered hydrogen bonds in the crystalline region.

Summary: In this study, a synergistically catalyzed atom transfer radical polymerization (ATRP) induced and controlled by the interplay between ball milling (BM) and piezoelectric nanoparticles (piezoNPs) was demonstrated for sustainable and eco-friendly polymer synthesis. The BM-induced electron transfer was achieved through the deformation of piezoNPs under impact force, acting as an external stimulus to mediate polymerization. The fabrication of a polymer with a well-defined molecular weight and low polydispersity was successfully achieved with ppm level copper loading. High-molecular-weight polymers ranging from 33 to 74 kDa were prepared by DMSO-assisted grinding. Besides, the ATRP approach showed good performance in terms of the availability of water as a liquid-assisted grinding additive, the recyclability of piezoNPs, and the formation of cross-linker-free composite resin, making it a green and practical option alongside existing heat-, electro-, and photo-induced methods.

Summary: Highly ordered TiO2 nanotube arrays (TNTAs) and their heterostructure nanocomposites were used as photocatalysts for efficient broadband photoinduced controlled radical polymerization (photoCRP). The combination of electron transfer acceleration from TNTAs' structure and the localized surface plasmon resonance (LSPR) effect with the formation of Schottky barrier via Au nanoparticle modification enabled efficient UV-visible light responsive photoCRP. The resulting polymers exhibited high conversion, living chain-ends, tightly regulated molecular weights, and excellent temporal control properties.

Summary: 4D printing has been a research hotspot in recent years. However, the limited availability of elastomer materials that can achieve reversible two-way shape memory effect (2W-SME) through selective laser sintering (SLS) has hindered the applications of 4D printing. This study successfully synthesizes a series of thermoplastic polyamide elastomers (TPAEs) with excellent thermal stability, flexibility, and resilience. The newly developed TPAE material not only expands the range of 4D printable materials, but also shows potential in the fields of soft robots, temperature sensors, and aerospace equipment.

Summary: The primary focus of structurally tailored and engineered macromolecular (STEM) gels is the postsynthesis polymeric modifications by grafting from the active sites. Reversible-deactivation radical polymerization (RDRP) techniques have been employed to more precisely tailor and tune STEM gels. Compared with atom transfer radical polymerization (ATRP) and reversible addition-fragmentation chain transfer polymerization (RAFT), nitroxide-mediated polymerization (NMP) has the advantages of simple components and pure products.

However, this study presents a simple and effective method to improve the dispersibility and thermal conductivity of BNNS by grafting polyacrylic acid (PAA) and immobilizing AuNPs onto BNNS. The resulting hybrid filler exhibits lower interfacial thermal resistance and higher thermal conductivity, making it suitable for high-efficiency thermal management materials in electronic devices.
