Summary: Biomass-derived cellulose carbon aerogels with a 3D network structure were synthesized from Typha Orientalis (TO). The TO cellulose carbon aerogels have light mass, super-hydrophobicity, and large specific surface areas, making them suitable for multifunctional adsorbent materials in various applications. The research demonstrates the material's hydrogen storage capacity, CO2 adsorption capacity, and its promising reusability for o-xylene adsorption, indicating its potential for energy storage and environmental protection.

Summary: The adsorption technique is widely used in water purification, and this research focuses on the iodide removal performance of two high-surface-area carbon aerogels. The results show that both aerogels have outstanding adsorption capacity and their surface chemistry plays a distinct role in the removal. The study also found that the kinetics of iodide removal followed a first-order reaction with different half-lives for each aerogel.

Summary: In this work, a double-cross-linking strategy is used to prepare compressible COF/chitosan (COF/CS) aerogels under mild conditions. The resulting aerogels have a highly porous structure and low density, enabling self-floating and practical applications. This method offers a facile and eco-friendly approach for producing COF-based aerogels with potential applications in environmental remediation.

Summary: Researchers have designed and fabricated a hybrid material by encapsulating covalent organic frameworks (COFs) into ultralight cellulose aerogels for efficient iodine capture. The hybrid aerogels exhibit excellent absorption performances and high uptake capacities toward solvent-dissolved and vaporized iodine. Moreover, the aerogels can be shaped into columns for continuous operations, providing a new way for COF materials shaping and inspiring the design of high-performance iodine capture platforms.

Summary: The global push toward decarbonization and electrification has led to a growing research effort to achieve higher device performance goals. Thick electrodes are being explored as a way to increase the fraction of active materials in electrochemical energy storage devices (EESDs), but overcoming ion-transport limitations is a challenge. Promising strategies, such as additive manufacturing techniques and the development of 3D-printable inks and resins, are being identified to address these limitations and improve the performance of EESDs.

Summary: This paper introduces a multifunctional aerogel based on graphene/silk, in which a highly ordered three-dimensional reduced graphene oxide (rGO) conductive network is established through an alkali-induced hydrothermal self-assembly strategy, and silk fibroin (SF) is uniformly distributed throughout the network by electrostatic interactions with graphene oxide (GO). The aerogel exhibits resistance variation with compression and can be used for flexible pressure sensors, with good linear response, stability, and durability, as well as applications in health monitoring, speech recognition, and motion capture.

Summary: Nowadays, there is a growing concern about environmental pollution caused by fossil fuel-based products, leading to the need for environmentally friendly and reusable materials. This study developed a novel method to fabricate biomass carbon aerogel from coconut pith-derived cellulose, which is a major cause of environmental issues. By using polyamide amine-epichlorohydrin (PAE) to cross-link cellulose fibers and subsequent freezing and lyophilization, cellulose aerogels with low density, high porosity, and excellent hydrophobicity were obtained. The pyrolyzed cellulose aerogels showed a high adsorption capacity for oils and solvents and maintained a minimal decline after multiple adsorption-regeneration cycles. This method has great potential in oil spill recovery and wastewater treatment.

Summary: This study investigates the use of chitosan hydrogel microspheres as a template for growing an extended network of MOF-type HKUST-1. Different drying methods (supercritical CO2, freeze-drying, and vacuum drying) were used to generate three-dimensional polysaccharide nanofibrils embedding MOF nanoclusters. The resulting HKUST-1@Chitosan beads exhibit uniform and stable loadings of HKUST-1 and were used for the adsorption of CO2, CH4, Xe, and Kr. The maximum adsorption capacity of CO2 was found to be 1.98 mmol center dot g(-1) at 298 K and 1 bar, which is significantly higher than those of most MOF-based composite materials. Based on Henry's constants, thus-prepared HKUST-1@CS beads also exhibit fair selectivity for CO2 over CH4 and Xe over Kr, making them promising candidates for capture and separation applications.
