Chlorinated aliphatic hydrocarbons (CAHs) are prevalent groundwater contaminants at industrial sites in China. This pilot-scale study evaluated in-situ anaerobic bioremediation of CAHs-contaminated groundwater in a low-permeability bedrock fracture zone at depths up to 40 m. A self-developed anaerobic dechlorinating culture (BS-1), containing Dehalococcoides, Desulfitobacterium, and Dehalogenimonas, was injected alongside carbon sources (sodium citrate and emulsified vegetable oil) and nutrients. Pressurized nitrogen gas injection enhanced the distribution of amendments, achieving a radius of influence of 5.0 m. Over 399 days of monitoring, the combined use of slow-release and soluble carbon sources maintained anaerobic conditions (ORP < -100 mV) for over one year, providing sustained electron donors. The emulsified vegetable oil reduced injection frequency and operational costs. The BS-1 culture effectively dechlorinated vinyl chloride, cis-1,2-dichloroethylene, trichloroethylene, and chloroform, achieving removal efficiencies exceeding 95%. At times, groundwater quality met the Class IV standard of GB/T 14848-2017. This study demonstrates a green, economical, and effective solution for CAH-contaminated site remediation, with significant engineering application potential.

The global cold chain consumes vast amounts of energy and emits greenhouse gases, while many regions lack proper refrigeration. To address this, we developed a dual-layer electrospun membrane (PZ-PML) for energy-free fruit preservation. The top PVDF-HFP/ZIF-8 layer offers 97.64% solar reflectance and 92.5% mid-infrared emissivity, providing 70 W/m2 radiative cooling. The bottom PAN/MIL-101/LiCl layer, with 2.18 g/g water uptake at 80% RH, delivers ~156 W/m2 evaporative cooling, lowering surface temperature by 6.1 °C under ~400 W/m2 irradiation. The membrane also shows ≥99% antibacterial efficiency against E. coli and S. aureus. Applied to strawberries, it reduced dehydration to 20.2% after 9 days, compared to 68.2% and 74.4% in controls. Additionally, it demonstrates durability, superhydrophobicity, and UV stability. This scalable solution offers energy-free fruit cooling, reducing postharvest losses while maintaining quality and safety.

Lignocellulose-based electromagnetic interference (EMI) shielding materials are gaining prominence across multiple sectors, driven by the growing EMI issues associated with rapid advances in communication technologies and electronic devices. These materials have demonstrated significant superiority over traditional EMI shielding solutions, which are often hampered by high cost and environmental concerns. This review emphasizes the excellent potential of lignocellulose as a cost-effective and flexible alternative to deliver the hierarchical structures and functional properties that qualify it for EMI shielding applications. The underlying EMI shielding mechanisms are then elucidated, with a focus on the benefits conferred by lignocellulose in such material systems. Furthermore, typical fabrication strategies for lignocellulose-based EMI shielding materials are comprehensively summarized, along with a discussion of their emerging applications in diverse scenarios. Finally, the challenges encountered in developing lignocellulose-based EMI shielding materials and their significant prospects for future boosting high-performance design and application are also outlined. The insights presented herein are expected to promote the development of efficient and green lignocellulose-based EMI shielding materials that meet the evolving demands of modern society.
