The sustainable utilization of biochar produced from biomass waste could substantially promote the development of carbon neutrality and a circular economy. Due to their cost-effectiveness, multiple functionalities, tailorable porous structure, and thermal stability, biochar-based catalysts play a vital role in sustainable biorefineries and environmental protection, contributing to a positive, planet-level impact. This review provides an overview of emerging synthesis routes for multifunctional biochar-based catalysts. It discusses recent advances in biorefinery and pollutant degradation in air, soil, and water, providing deeper and more comprehensive information of the catalysts, such as physicochemical properties and surface chemistry. The catalytic performance and deactivation mechanisms under different catalytic systems were critically reviewed, providing new insights into developing efficient and practical biochar-based catalysts for large-scale use in various applications. Machine learning (ML)-based predictions and inverse design have addressed the innovation of biochar-based catalysts with high-performance applications, as ML efficiently predicts the properties and performance of biochar, interprets the underlying mechanisms and complicated relationships, and guides biochar synthesis. Finally, environmental benefit and economic feasibility assessments are proposed for science-based guidelines for industries and policymakers. With concerted effort, upgrading biomass waste into high-performance catalysts for biorefinery and environmental protection could reduce environmental pollution, increase energy safety, and achieve sustainable biomass management, all of which are beneficial for attaining several of the United Nations Sustainable Development Goals (UN SDGs) and Environmental, Social and Governance (ESG). © 2023 The Authors

Photocatalytic and photoelectrocatalytic H 2 O 2 production has been identified as a significant pathway within environmental pollution control, green energy, medical treatment, sterilization and disinfection. However, conventional single-material photocatalysts struggle to fulfill the stringent criteria of high efficiency, stability, cost-effectiveness, and responsiveness to visible light. The elevated recombination rates of photogenerated charge carriers, coupled with the suboptimal utilization of visible light, have collectively constrained the photocatalytic and photoelectrocatalytic H 2 O 2 production. Heterojunction catalysts for the production of H 2 O 2 has become a focal point of research. This review commences by elucidating the fundaments underlying the photocatalytic and photoelectrocatalytic H 2 O 2 production. Subsequently, it delineates the distinctive electron transfer mechanisms of Z-scheme and S-scheme heterojunctions, which exhibit enhanced efficiency in the photocatalytic and photoelectrocatalytic H 2 O 2 production, along with a summary of strategies for the improvement of photocatalyst and photoelectrocatalyst performance. Furthermore, this review also outlines the latest fabrication strategies, state-of-the-art in-situ characterization techniques, machine learning and density functional theory (DFT) simulations for Z-scheme or S-scheme catalysts for the photocatalytic and photoelectrocatalytic H 2 O 2 production, and briefly describes the multifunctional applications in H 2 O 2 production. Ultimately, the review contemplates the prospective developmental trajectories and application potential of these heterojunction configurations for the photocatalytic and photoelectrocatalytic H 2 O 2 production.

Online sequential extreme learning machine (OS-ELM) is a method of online learning, which can handle the problem of data arriving or chunk-by-chunk with varying chunk size. However, the input weights (connections between the input and hidden layers) and the hidden layer biases of OS-ELM are randomly determined, which will cause an inaccurate classification result, that varied a lot, and in the field of fault diagnosis, the diagnostic mode is mainly divided into two types: online and offline. At present, many offline learning and diagnostic methods have been proposed by researchers, but there are few online sequential learning and monitoring methods. Therefore, in this paper, a new classification method PSO-OSELM (Particle Swarm Optimization and Online Sequential Extreme Learning Machine) is proposed for classification and engineering application. In the PSO-OSELM method, PSO is used to determine the optimal input weights and thresholds of OS-ELM, which minimizing the classification error of OS-ELM. Contrastive experiments between PSO-OSELM and OSELM have been conducted on wine datasets. The results show that PSO-OSELM has higher classification accuracy than OS-ELM, and PSO-OSELM is further applied to diagnose the faults of roller bearing. It can be seen from the training and testing results that the fault classification accuracy of PSO-OSELM is better than OS-ELM © Proceedings of the 26th International Congress on Sound and Vibration, ICSV 2019.

Triclocarban (TCC) is the principal component in personal and health care products because it is a highly effective, broad-spectrum, and safe new antibacterial agent. TCC has recently been discovered in aquatic creatures and has been shown to constitute a health danger to aquatic animals. Although several studies have looked into toxicological effects of TCC on a variety of aquatic animals, from algae to fish, the possible gut-toxicity molecular pathway in zebrafish has never been thoroughly explored. We investigated the gut-toxic effects of TCC on zebrafish by exposing them to different TCC concentrations (100, 1,000 g/L) for 21 days. We discovered for the first time that MAPK and TLR signaling pathways related to gut diseases were significantly altered, and inflammation (up-regulation of TNF-α, IL-6, and IL-1) caused by TCC was confirmed to be largely mediated by AHR and its related cytokines, using the results of qPCR, transcriptome analysis, and molecular docking (AHR, AHRR, CYP1A1 and CYP1B1). Furthermore, high-throughput 16S rDNA sequencing demonstrated that TCC exposure reduced bacterial diversity and changed gut microbial composition, with the main phyla Fusobacteria and Proteobacteria, as well as the genera Cetobacterium and Rhodobacteraceae, being the most affected. TCC exposure also caused damage to the gut tissue, including an increase in the number of goblet cells and a reduction in the height of columnar epithelium and the thickness of the muscular layer, as shown by H&E staining. Our findings will aid in the understanding of the mechanism of TCC-induced aquatic toxicity in aquatic species. © 2022, The Authors. All rights reserved.

Real-time 3D human pose estimation is crucial for human-computer interaction. It is cheap and practical to estimate 3D human pose only from monocular video. However, recent bone splicing based 3D human pose estimation method brings about the problem of cumulative error. In this paper, the concept of virtual bones is proposed to solve such a challenge. The virtual bones are imaginary bones between non-adjacent joints. They do not exist in reality, but they bring new loop constraints for the estimation of 3D human joints. The proposed network in this paper predicts real bones and virtual bones, simultaneously. The final length of real bones is constrained and learned by the loop constructed by the predicted real bones and virtual bones. Besides, the motion constraints of joints in consecutive frames are considered. The consistency between the 2D projected position displacement predicted by the network and the captured real 2D displacement by the camera is proposed as a new projection consistency loss for the learning of 3D human pose. The experiments on the Human3.6M dataset demonstrate the good performance of the proposed method. Ablation studies demonstrate the effectiveness of the proposed inter-frame projection consistency constraints and intra-frame loop constraints. Copyright © 2021, The Authors. All rights reserved.

Hydrogel-anchored caffeic acid-copper ions coating: Integrated defensive and offensive strategy for synergistic antifouling

Chemical engineering Journal 2025年 515卷

marine biofouling poses significant global challenges for maritime activities, resulting in serious economic losses and environmental issues. Biomimetic coatings have drawn extensive attentions due to their environmentally friendly antifouling properties. Herein, an innovative strategy is reported for constructing antifouling coating composed of caffeic acid-copper ions (CA-Cu2+) anchored on a Kevlar hydrogel. The resultant coating achieves good adhesion (1.3 MPa) to various substrates via the bioinspired polymerization of metal-polyphenol networks (MPNs). The hydrophilic nature and synergistic antimicrobial effects enable efficient self-cleaning, anti-protein (100 %), anti-bacterial (100 %), and anti-algae (99.84 %) performance. Strikingly, the coating exhibits superior acid and alkali tolerance, abrasive resistance, and long-term stability over 60 days in real seawater, owing to the hydrogen bonds and coordination interactions between the Kevlar hydrogel and the CA-Cu2+ functional layer. Further research demonstrates that the antifouling performance are realized via the synergistic antifouling models. The hydration layer formed by the synergistic action of the hydrogel and CA effectively prevents the attachment of microorganisms, and the chemodynamic antibacterial mode triggered by Cu2+ can actively kill the microorganisms adhered to the material surface. Importantly, the Cu2+ release profile of the H/PCA-Cu coating meets the environmental requirements. The "defensive" and "offensive" integrated antifouling strategy provides groundbreaking performance for broad-spectrum biofouling control, which greatly desired for marine facilities. Our work not only expands the family of MPNs application in marine antifouling coatings, but also pioneers a rational pathway toward developing long-lasting and environmentally friendly broad-spectrum antifouling coatings. © 2025 Elsevier B.V.

Nationwide screening of landfill-derived organohalide-respiring bacteria elucidates a unique cross-feeding interaction for microbial reductive dehalogenation

Water Research 2025年 284卷 123964页

作者： Rui Shen Qihao Li Qihong Lu Zhili He Xiaosong He Shanquan Wang School of Environmental Science and Engineering Environmental Microbiomics Research Center Guangdong Provincial Key Laboratory of Environmental Pollution Control and Remediation Technology Sun Yat-Sen University Guangzhou 510006 PR China Southern Marine Science and Engineering Guangdong Laboratory (Zhuhai) Zhuhai 519080 PR China State Key Laboratory of Environmental Criteria and Risk Assessment State Ministry of Ecology and Environment Key Laboratory of Simulation and Control of Groundwater Pollution Chinese Research Academy of Environmental Sciences Beijing 100012 PR China

Landfill as a major reservoir of organohalide pollutants provides a unique niche for selective enrichment of organohalide-respiring bacteria (OHRB), playing a critical role in cycling of anthropogenic organohalides in natural environments. Nonetheless, information on the landfill-derived OHRB and associated microbial interactions for microbial reductive dehalogenation remains unknown. In this study, dehalogenation microcosms were established with nationwide landfill leachate samples collected from 45 cities in China, which dechlorinated a common anthropogenic organohalide - tetrachloroethene - to chloroethenes in varied extent. Both the 16S rRNA gene amplicon-sequencing and metagenomics analyses suggested critical roles of unknown Dehalococcoidia and phylogenetically-diverse facultative OHRB in microbial reductive dehalogenation in landfills. Further culture-based interaction examination showed a complicated metabolic network among OHRB, sulfate-reducing bacteria, fermenting bacteria and methanogenic archaea. Particularly, the acetate competition between obligate/facultative OHRB and methanogens were shown to have a threshold concentration of 0.06/0.20 mM, above which the methanogenic Methanosarcina became more competitive, in contrast to the dominance of acetotrophy of obligate/facultative OHRB under the threshold concentration. Accordingly, the Methanosarcina and OHRB preferred acetate transfer from fermenting Clostridium and sulfate-reducing Desulfovibrio , respectively, which was determined by the “Maximum Power Principle” to maximize ecological fitness through optimizing energy utilization efficiency. This study provided the first insight into landfill-derived OHRB and their metabolic interactions with associated functional microorganisms, which could support future bioremediation of organohalide-contaminated landfills.
