Over two thousand mud volcanoes have been documented worldwide, predominantly forming in geologically active regions characterized by rapid sedimentation, recent magmatic activity, and compressional tectonics. These features originate from gravitative instability and fluid overpressure, which induce hydrofracturing of impermeable strata, allowing the release of water, gas, and sediments to the surface. As a result, mud volcanoes occur across a range of tectonic and sedimentary settings, including active margins, accretionary complexes, thrust belts, and deep sedimentary basins. They are generally classified as either submarine or terrestrial mud volcanoes, with the former typically associated with tectonic deformation and the later with sediment accumulation in continental settings. Beyond their geological significance, mud volcanoes contribute substantially to global geochemical and biogeochemical processes, influencing methane production and consumption, nutrient cycling, and organic matter transformation. Additionally, microbial communities are essential in the formation and maintenance of mud volcano structures by contributing to the biomineralization of carbonates and sulfates. The microbial communities found in different mud volcanoes are diverse, and their composition can vary based on location, depth, and geochemical conditions. Moreover, these microbial communities have evolved to utilize diverse sources of energy, including hydrogen, methane, and sulfur, to facilitate metabolic processes. This review summarizes the current insights into the formation, distribution, and environmental constraints of mud volcanoes, while highlighting the ecological relevance and metabolic capabilities of associated microbial communities based on metagenomics data to support interdisciplinary research into geobiological interactions in extreme ecosystems. © 2025

Using large-scale, real-time, quantum dynamics calculations, we present a detailed analysis of electronic excitation transfer (EET) mechanisms in a multiparticle plasmonic nanoantenna system. Specifically, we utilize a real-time, time-dependent, density functional tight binding (RT-TDDFTB) approach to provide a quantummechanical description (at an electronic/atomistic level of detail) for characterizing and analyzing these systems, without recourse to classical approximations. We also demonstrate highly long-range electronic couplings in these complex systems and find that the range of these couplings is more than twice the conventional cutoff limit considered by Förster resonance energy transfer (FRET)-based approaches. Furthermore, we attribute these unusually long-ranged electronic couplings to the coherent oscillations of conduction electrons in plasmonic nanoparticles. This long-range nature of plasmonic interactions has important ramifications for EET;in particular, we show that the commonly used "nearestneighbor" FRET model is inadequate for accurately characterizing EET even in simple plasmonic antenna systems. These findings provide a real-time, quantummechanical perspective for understanding EET mechanisms and provide guidance in enhancing plasmonic properties in artificial light-harvesting systems. © 2018 by TechConnect.

Introduction: The COVID-19 pandemic has created an urgent demand for research, which has spurred the development of enhanced biosafety protocols in biosafety level (BSL)-3 laboratories to safeguard against the risks associated with handling highly contagious pathogens. Laboratory management failures can pose significant hazards. Methods: An external system captured images of personnel entering a laboratory, which were then analyzed by an AI-based system to verify their compliance with personal protective equipment (PPE) regulations, thereby introducing an additional layer of protection. A deep learning model was trained to detect the presence of essential PPE items, such as clothing, masks, hoods, double-layer gloves, shoe covers, and respirators, ensuring adherence to World Health Organization (WHO) standards. The internal laboratory management system used a deep learning model to delineate alert zones and monitor compliance with the imposed safety protocols. Results: The external detection system was trained on a dataset consisting of 4112 images divided into 15 PPE compliance classes. The model achieved an accuracy of 97.52 % and a recall of 97.03 %. The identification results were presented in real time via a visual interface and simultaneously stored on the administrator's dashboard for future reference. We trained the internal management system on 3347 images, achieving 90 % accuracy and 85 % recall. The results were transmitted in JSON format to the internal monitoring system, which triggered alerts in response to violations of safe practices or alert zones. Real-time notifications were sent to the administrators when the safety thresholds were met. Conclusion: The BSL-3 laboratory monitoring system significantly reduces the risk of exposure to pathogens for personnel during laboratory operations. By ensuring the correct use of PPE and enhancing adherence to the imposed safety protocols, this system contributes to maintaining the integrity of BSL-3 facilities

Enhancing methanogenesis from long-chain fatty acids (LCFA) and enrichment of novel bacteria with resuscitation-promoting factors

引用

Bioresource Technology 2025年 432卷 132663页

作者： Fang, Bo Liu, Yi-Fan Wei, Hao-Xun Zhou, Lei Yang, Shi-Zhong Gu, Ji-Dong Mu, Bo-Zhong State Key Laboratory of Bioreactor Engineering and School of Chemistry and Molecular Engineering East China University of Science and Technology 130 Meilong Road Shanghai200237 China Environmental Science and Engineering Program Guangdong Technion Israel Institute of Technology 241 Daxue Road Guangdong Shantou515063 China Engineering Research Center of Microbial Enhanced Oil Recovery East China University of Science and Technology 130 Meilong Road Shanghai200237 China

Long-chain fatty acids (LCFA) are important intermediate metabolites in lipid hydrolysis during anaerobic digestion for biogas production. High LCFA loads inhibit microbial activity by toxicity, impairing the coupling of β-oxidation and methanogenesis, thus reducing LCFA degradation efficiency. This study employed and tested seven stimulants, including the resuscitation-promoting factors (Rpf and YeaZ), the quorum-sensing molecules (cAMP, and AHLs), the chemical stimulants (pyruvate), the growth promoter (fumarate), and yeast extract + peptone (YP) for enhancement of methanogenic degradation of LCFA. The results indicate that the chemical stimulants and resuscitation-promoting factors enhanced maximum methane-production rate 1.58 to 2.20 fold versus the NS, reducing the lag phase by 1.46–9.76 days. Analysis of the microbial community composition revealed that the quorum sensing factors only increased species richness, while Rpf, YeaZ fumarate, and YP stimulated the growth of core members of the communities. Metagenomic analysis detected three previously unreported LCFA-degrading bacterial taxa, Marinisomatota, Thermoanaerobaculaceae and Pelomonas. Particularly, Rpf and YeaZ significantly enriched LCFA-degrading bacteria such as Syntrophomonadaceae, Leptospiraceae, and Marine Group B within the core species, while YeaZ also stimulated methanogenic bacteria, possibly due to resuscitating dormant microbes from unfavorable conditions. Syntrophic interactions between LCFA degraders and non-degraders, rather than methanogen abundance, govern methanogenic LCFA degradation. These results demonstrate that the use of stimulants is an effective approach to enhance LCFA degradation and provide a new pathway for energy recovery. © 2025 Elsevier Ltd

Non-thermal plasma-catalytic processes for CO2 conversion toward circular economy: fundamentals, current status, and future challenges

引用

environmental science and Pollution Research 2024年 1-21页

作者： Mukhtar, Ahmad Saqib, Sidra Mohotti, Dinithi Ndeddy Aka, Robinson Jr. Hossain, Mokter Agyekum-Oduro, Ekow Wu, Sarah Department of Chemical and Biological Engineering University of Idaho MoscowID83843 United States Environmental Science Program University of Idaho MoscowID83844 United States

Practical and energy-efficient carbon dioxide (CO2) conversion to value-added and fuel-graded products and transitioning from fossil fuels are promising ways to cope with climate change and to enable the circular economy. The carbon circular economy aims to capture, utilize, and minimize CO2 emissions as much as possible. To cope with the thermodynamic stability and highly endothermic nature of CO2 conversion via conventional thermochemical process, the potential application of non-thermal plasma (NTP) with the catalyst, i.e., the hybrid plasma catalysis process to achieve the synergistic effects, in most cases, seems to promise alternatives under non-equilibrium conditions. This review focuses on the NTP fundamentals and comparison with conventional technologies. A critical review has been conducted on the CO2 reduction with water (H2O), methane (CH4) reduction with CO2 to syngas (CO + H2), CO2 dissociation to carbon monoxide (CO), CO2 hydrogenation, CO2 conversion to organic acids, and one-step CO2–CH4 reforming to the liquid chemicals. Finally, future challenges are discussed comprehensively, indicating that plasma catalysis has immense investigative areas. © The Author(s) 2024.

Understanding the strength behavior and leaching characteristics of mining tailings stabilized with alkali-activated cements in the short, medium, and long term is crucial for the feasibility of material applications. In this context, this study assessed the stabilization/solidification of iron ore tailings (IOT) using alkali-activated binder (AAB) composed of sugarcane bagasse ash and eggshell lime at curing times of 7, 28, 60, 90, 180, and 365 days. Additionally, leaching tests were conducted, along with the examination of possible changes in the chemical and mineralogical composition resulting from exposure to acidic environments. Tests included unconfined compression strength (UCS), leaching, X-ray diffraction, and Fourier-transform infrared spectroscopy for the IOT-AAB mixtures. The highest increase in UCS was observed between 7 and 60 days, reaching 6.47 MPa, with minimal variation thereafter. The AAB-bonded IOT exhibited no metal toxicity over time. Elements Ba, Mn, Pb, and Zn present in IOT and ash were encapsulated in the cemented matrix, with complete encapsulation of all metals observed from 90 days of curing time. The mineralogy of the stabilized/solidified tailings showed no changes resulting from leaching tests. Characteristic bands associated with the presence of N-A-S–H gel were identified in both pre-leaching and post-leaching samples for all curing times analyzed. Exposure to acidic environments altered bands related to carbonate bonds formed in the IOT-AAB mixture. © The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature 2024.
