Dye pollution has become one of the main pollution sources in the world, and the water pollution caused by it needs people's close attention. Nanocellulose is a sustainable biomaterial that is abundant in nature and has many advantages, such as high crystallinity, high hydrophilicity, high Young's modulus, high strength, and high surface activity. Its surface has abundant hydroxyl functional groups, making nanocellulose and its composites well used in adsorbing dyes from wastewater. In this paper, the adsorption mechanism and adsorption process of nanocellulose and its derived materials on cationic dyes and anionic dyes were discussed comprehensively. The specific adsorption mechanism was summarized, including adsorption isotherm model, adsorption kinetics process, adsorption thermodynamics process, etc. In addition, this article also looks forward to the future development of nanocellulose and related materials in the field of water treatment, and proposes new development directions.

As shale gas is an unconventional energy source, it is believed to be essential for achieving green resource development and improving the energy supply-demand balance. However, owing to shale's substantial anisotropic properties and various microstructures, its gas flow characteristics and transport mechanisms are exceedingly complex. Therefore, accurately predicting gas permeability evolution in shale pores was considered to be important for energy development.

Context: TEMPO-oxidized cellulose nanofibers (TOCNFs) show significant potential for developing high-performance resistive humidity sensors due to their hydrophilicity and structural adaptability. However, the underlying atomic-scale mechanisms governing their humidity response remain poorly understood. Using molecular dynamics simulations, this study investigates how crystal facets, nanopore widths, and humidity levels influence the surface wettability, water permeability, and swelling of TOCNFs.

The primary extraction way for unconventional oil/gas resources is hydraulic fracturing to alter the reservoir for commercial production. However, hydraulic fracturing technology consumes a large amount of water, and the flowback water can easily be mixed with hydrocarbon substances to form emulsions. To achieve the recycling of water, it is necessary to develop an efficient continuous demulsification method for treating the flowback fluid.

Spatially resolved characterization of proteoforms has substantial potential to significantly advance the understanding of physiological and disease mechanisms. However, challenges remain regarding throughput and coverage. A robust method is developed for high-throughput proteoform imaging (HTPi) by combining matrix-assisted laser desorption ionization mass spectrometry imaging (MALDI MSI) and region-specific top-down proteomic analysis.

Fluoride is ubiquitously present in the natural environment, and its excessive levels can pose serious threats to human health and industrial production. Among various fluoride pollution control methods, adsorption is recognized for its optimal cost-effectiveness and adaptability. The mechanism of fluoride adsorption and the adsorption capacities of various modified adsorbents have been comparatively analyzed:natural minerals, biomass materials, metal oxides, and several emerging types of adsorbents, among which metal-based adsorbents show the best performance.
