Summary: The preparation of high-performance electrode materials for supercapacitors is currently in high demand. Covalent organic frameworks (COFs), as a new type of organic porous material with ordered pore structure, high specific surface area, and designability, show great potential as electrode materials. However, the poor conductivity of COFs limits their application in supercapacitors. In this study, a highly crystalline triazine-based covalent organic framework, DHTA-COF, was in-situ grown on a modified α-Al2O3 substrate to obtain Al2O3@DHTA-COF composites. Some of the composites maintained crystallinity, stability, and a vesicular structure. Compared to the precursors α-Al2O3 and DHTA-COF, the 50%Al2O3@DHTA-COF composite exhibited superior electrochemical properties as electrode materials for supercapacitors, with specific capacitance values 6.2 and 9.6 times higher than DHTA-COF and α-Al2O3-CHO, respectively. Additionally, the 50%Al2O3@DHTA-COF electrode material showed long-term cycling stability even after 6000 charge-discharge cycles. This study provides a reference for the development of COF-based composite materials for energy storage.

Summary: This study successfully fabricated a lightweight composite phase change material (PCM) without liquid phase leakage, addressing the requirements for high enthalpy and solar-thermal energy conversion and storage. By utilizing a combination of melamine foam (MF), graphene nanoplatelets (GNP), and carbon nanotubes (CNT) as the supporting framework, along with octadecane as the core PCM, the composite PCMs with an 85.8% loading amount exhibited comparable phase transition enthalpy to that of pure octadecane. Furthermore, the composites showed minimal alterations in thermal performance after 350 simulated hot and cold cycles, and exhibited exceptional abilities in solar-thermal conversion and electrothermal conversion, with a photothermal conversion efficiency exceeding 95%. Consequently, the developed composite PCMs demonstrate significant potential for applications in thermal energy storage and conversion.

Summary: The development of new scaffolds and materials for tissue engineering is a wide and open realm of material science. Among solutions, the use of biopolymers represents a particularly interesting area of study due to their great chemical complexity that enables creation of specific molecular architectures. However, biopolymers do not exhibit the properties required for direct application in tissue repair-such as mechanical and electrical properties-but they do show very attractive chemical functionalities which are difficult to produce through in vitro synthesis. The combination of biopolymers with nanostructured carbon fillers could represent a robust solution to enhance composite properties, producing composites with new and unique features, particularly relating to electronic conduction. In this paper, we provide a review of the field of carbonaceous nanostructure-containing biopolymer composites, limiting our investigation to tissue-engineering applications, and providing a complete overview of the recent and most outstanding achievements.

Summary: In the study, a clean and curved CNT structure with specified curvature radius was synthesized through micro perturbation, demonstrating that the curved structure can maintain high output delivery in transistors even though it limits the on/off ratio significantly. The resistance induced by localized strain and the extra current delivery capability of the inner walls play a crucial role in this phenomenon, which can be explained by the energy band diagram model. Among the curved CNTs, incommensurate double-walled CNTs with higher diameter difference are identified as optimal candidates for delivering high current output by limiting intertube charge transfer.

Summary: Fibre batteries are a promising technology that can be woven into flexible textiles to create compact, wearable and lightweight power solutions. However, current manufacturing methods are inefficient and cannot meet the demands of real applications.

Our method has achieved a three-orders-of-magnitude increase in fibre length compared to previous reports.

Summary: Solar-driven interfacial evaporation is a promising technology for water desalination. By controlling assembly pathways, a hybrid material consisting of vinyltrimethoxysilane and bacterial cellulose fibrous network was created, leading to robust aerogels with distinct wettability. The aerogels, with superhydrophilic or superhydrophobic surfaces, were integrated into a double-layered evaporator for efficient water desalination. The aerogel evaporator exhibited high water evaporation rates, lightweight, structural robustness, long-term stability, and excellent salt-resistance, highlighting the advantages of synthesizing aerogel materials from a single molecular unit.

Summary: Visual temperature sensors using fiber fluorescent imaging based on aggregation-induced emission (AIE)-functionalized CO2-based PPC have been developed. A three-in-one strategy involving AIE, chain transfer, and co-catalytic properties was used to synthesize AIEgen end-labeled PPC as a thermometer material. The fiber thermometer obtained by melt spinning converts the invisible temperature gradient information into different fluorescent colors visible to the naked eye. It enables high-resolution (±1°C, 10μm) multiscale temperature visualization applications in the range of -40 to 140 °C, including regional temperature detection and internal 1D/2D temperature mapping.

Summary: Despite the progress in stimuli-responsive fluorescent materials, the influence of confinement on the fluorescence properties of fluorescent molecules created by crystalline polymer remains unclear. Computational simulations reveal that confinement induces aggregation-induced emission luminogens (AIEgens) to adopt a more planar conformation, resulting in a red-shifted emission spectrum. Further investigation shows that different fluorescence colors are activated by confinement created by various polymer crystalline forms. This confinement fluorescence effect is attributed to the spatial dimensions of the polymer amorphous layer between lamellar crystals where the AIEgens are located.
