文摘Biological contaminants(BCs),including but not limited to various pathogens and their endogenous pol-lutants such as intracellular pathogens and antimicrobial resistance genes(ARGs),are ubiquitously detected in effluent of wastewater and drinking water treatment systems which were originally designed to remove common indicator bacteria,resulting in potential impacts on public health.Although there are many emerging technologies that showing promising antimicrobial effects,few have progressed to the actual water scenarios.It’s crucial to understand the main knowledge gaps and thereby design the future developments to better meet engineering requirements.In this review,we first summarize the perfor-mance of conventional water treatment towards BCs removal.Then we showcase the advances of proof-of-concept strategies,including nanotechnology,advanced oxidation process,biological control process and integrated techniques,for BCs control in light of antimicrobial mechanisms,characteristics,proper niches in water treatment,challenges and latest improvements.Further,we proposed a semi-quantitative framework coupling life cycle assessment(LCA)and analytic hierarchy process(AHP)to assess and compare the application potential of representative pilot technologies,in which the antimicro-bial effects,economic issues and sustainability are comprehensively considered.For wastewater treat-ment,non-thermal plasma weights highest among the emerging technologies and outperforms conventional disinfection in terms of efficacy indicators(overall inactivation rate,ARGs removal rate,and growth inhibition),but fall behind overall mainly due to more energy input.Bacteriophage-based treatment has the potential to synergistically inactive the persistent pathogens in combination with con-ventional disinfection,serving as a cost-effective and environmental-friendly supplement.For drinking water treatment,the integrated photocatalytic nanocomposite receives the highest application potential among the emerging technologies and appears to be supplementary or even alternative next-generation disinfectants.This review shares valuable insights to propel the proof-of-concept antimicrobial trials towards industrial procedures.

文摘With the rapid growth of the global population and the increasing demand for healthier diets,improving the nutrient utilization efficiency of staple food crops has become a critical scientific and industrial chal-lenge,prompting innovation in food processing technologies.This review introduces first the common nutritional challenges in the processing of staple food crops,followed by the comprehensive examination of research aiming to enhance the nutritional quality of staple food crop-based foods through innovative processing technologies,including microwave(MW),pulsed electric field(PEF),ultrasound,modern fer-mentation technology,and enzyme technology.Additionally,soybean processing is used as an example to underscore the importance of integrating innovative processing technologies for optimizing nutrient utilization in staple food crops.Although these innovative processing technologies have demonstrated a significant potential to improve nutrient utilization efficiency and enhance the overall nutritional pro-file of staple food crop-based food products,their current limitations must be acknowledged and addressed in future research.Fortunately,advancements in science and technology will facilitate pro-gress in food processing,enabling both the improvement of existing techniques as well as the develop-ment of entirely novel methodologies.This work aims to enhance the understanding of food practitioners on the way processing technologies may optimize nutrient utilization,thereby fostering innovation in food processing research and synergistic multi-technological strategies,ultimately providing valuable references to address global food security challenges.
文摘High costs,technical difficulties,and policy uncertainties are the main challenges in carbon capture technology investments.Therefore,innovative financial products are required to develop projects that overcome these difficulties.Some issues must be considered when developing innovative financial products.An important problem in this process is that these features cannot possibly exist together in the new financial product,because each of these features incurs some costs.Therefore,identifying the most important features of innovative financial products is necessary.Accordingly,this study develops a new and innovative financial product to increase the effectiveness of investments in carbon capture technologies.For this purpose,a novel artificial intelligence(AI)-based fuzzy decision-making model is constructed.First,the weights of the experts were calculated by considering AI methodology.Second,the factors affecting investment in carbon capture technologies were weighted using a spherical fuzzy DEMATEL.Finally,the financial features required for investments were ranked using the spherical fuzzy ARAS method.This study’s main contribution is its creation of a novel fuzzy decision-making model by integrating AI methodology with fuzzy decision-making theory.In this process,the weights of the experts are calculated using an AI approach.It is concluded that cost-effectiveness must be prioritized in the development of new financial products.Technological competence is another aspect that should be considered in this process.However,innovative financial products should include risk management and flexible financing.

文摘With the depletion of shallow mineral resources,mining operations are extending to greater depths and larger scales,increasing the risk of water inrush disasters,particularly from confined aquifers intersected by faults.This paper reviews the current state of research on fault-induced water inrushes in mining faces,examining the damage characteristics and permeability of fractured floor rock,the mechanical behavior of faults under mining stress,and the mechanisms driving water inrush.Advances in prevention technologies,risk assessment,and prediction methods are also summarized.Research shows that damage evolution in fractured floor rock,coupled with fluid-solid interactions,provides the primary pathways for water inrush.Stress-seepage coupling in porous media plays a decisive role in determining inrush potential.Mining-induced stress redistribution can activate faults,with parameters such as dip angle and internal friction angle controlling stress evolution and slip.Critical triggers include the hydraulic connectivity among faults,aquifers,and mining-induced fracture networks,followed by hydraulic erosion.A multi-pronged prevention framework has been developed,integrating precise fault detection,targeted grouting for water sealing,drainage to reduce water pressure,optimized waterproof coal pillar design,and dynamic risk assessment and prediction.However,gaps remain in understanding multi-physical field coupling under deep mining conditions,establishing quantitative criteria for fault activation-induced water inrush,and refining control technologies.Future work should focus on multi-scale numerical simulations,advanced active control measures,and intelligent,integrated prevention systems to clarify the mechanisms of fault-induced water inrush and enhance theoretical and technical support for mine safety.
