The objective of net-zero emissions involves a need for highly efficient geological storage of CO2. Deep saline aquifers are identified as the most favorable geological storage sites throughout the initial evaluation and subsequent implementation at pilot projects. The optimization of the microbubbles CO2 (MB CO2) injection strategy for enhancing carbon storage capacity in tight reservoirs is carried out to address issues related to the limited utilization of reservoir pores. This work directly observes the effect of variable injection conditions on CO2 transport in saturated cores at 320 K with pressure of 12.5 MPa. From the spatiotemporal evolution of the fluid phase distribution, the capillary fingering pattern is observed in all cases, while MB CO2 with greater mass transfer rates shows greater mobility within tiny pores. The flow of MB CO2 in sandstones is characterized by channelling pattern, which is determined by stratification and property differences of the core. The results confirm that CO2 saturation increased by 11.2% at gas breakthrough time, and 15.5% at steady state using the MB CO2 injection strategy. Differences in local CO2 saturation levels are seen as a function of injection distance. By altering the flow rate of displacement phase, the most favorable results are found at capillary number (Ca) Ca =3.30×10-10 with a medium injection rate. The average CO2 saturation are found to be above 11.9% and 7.5% for higher and lower injection rates, respectively. © 2023, The Authors. All rights reserved.

Vanadia-based catalysts are widely applied in NOx reduction, while the promoting effect of WO3 and MoO3 is still under debate. Herein, we prepared V2O5/TiO2, V2O5-WO3/TiO2, and V2O5-MoO3/TiO2 catalysts and revealed that WO3 and MoO3 enhanced the activity of V2O5/TiO2, particularly under wet conditions. In situ DRIFTS, two-dimensional correlation spectroscopy (2D COS), and DFT calculations demonstrated that NH3 adsorption on Lewis acid sites of V2O5/TiO2 resulted in the formation of NH3ads-L1 (1284 cm-1, Ti sites of O=V-O-Ti) and NH3ads-L2 (1604 cm-1, V=O sites). By using 2D COS, we firstly found that the NH3ads-L1 exhibited higher reactivity towards NO to produce NH2NO* via NH2*, which was promoted by WO3. Moreover, WO3 and MoO3 doping inhibited H2O adsorption, and promoted its desorption at elevated temperature, thus protecting the V=O sites on V2O5/TiO2. Also, 2D COS analysis provides a new perspective for in-depth understanding of the active sites and intermediates in NH3-SCR reaction. © 2023, The Authors. All rights reserved.

With the increase of people's consumption of beef and milk products, a numerous amount of cow dung generates all over the world. However, the treatment efficiency of this cow dung remains at relative low level. Previous studies have shown that the addition of riboflavin-loaded conductive materials can promote direct interspecies electron transfer, leading to improved anaerobic digestion. However, its effect on the practical anaerobic digestion of cow dung remained unclear. In this study, carbon cloth loaded with riboflavin (carbon cloth-riboflavin) was added into an anaerobic digester treating cow dung. The carbon cloth-riboflavin reactor was operated stably at an OLR of 5 kgCOD/(m3·d) (HRT of 10 days), and showed higher COD removal efficiencies, methane production rates, and methane concentration than other two reactors. The metagenomic analysis revealed that Methanothrix on the surface of the carbon cloth predominantly utilized the CO2 reduction pathway for methane production, with this proportion being further enhanced after riboflavin addition, while Methanothrix in bulk sludge were using the acetate decarboxylation pathway. Furthermore, the carbon cloth-riboflavin positively influenced methanogenesis by enriching various major methanogenic pathways and activating a large number of enzymes associated with methane metabolism. Riboflavin's presence altered the microbial communities and the abundance of functional genes relate to DIET, ultimately leading to a better performance of anaerobic digestion for cow dung. © 2023, The Authors.

Human health/socioeconomic development is closely correlated to environmental pollution, highlighting the need to monitor contaminants in the real environment with reliable devices such as biosensors. Recently, variety of biosensors gained high attention and employed as application, in real-time, and cost-effective analytical tools for healthy environment. For continuous environmental monitoring, it is necessary for portable, cost-effective, quick, and flexible biosensing devices. These benefits of the biosensor strategy are related to the Sustainable Development Goals (SDGs) established by the United Nations (UN), especially with reference to clean water and sources of energy. However, the relationship between SDGs and biosensor application for environmental monitoring is not well understood. In addition, some limitations and challenges might hinder the biosensor application on environmental monitoring. Herein, we reviewed the different types of biosensors, principle and applications, and their correlation with SDG 6, 12, 13, 14, and 15 as a reference for related authorities and administrators to consider. In this review, biosensors for different pollutants such as heavy metals and organics were documented. The present study highlights the application of biosensor for achieving SDGs.

Cereal products can prevent the occurrence of chronic metabolic diseases such as hyperglycemia and hyperlipidemia. In this study, red kidney bean flour and wheat gluten were used as raw materials, and long-chain inulin phosphate monoester (PFXL) was added to improve the quality of miscellaneous grain dough, prepare high-quality steamed bread, and explore its health effect on type 2 diabetes. The results showed that the addition of PFXL improved the water distribution and rheological properties of coarse grain dough and enriched the flavor of coarse grain steamed bread. In addition, the glycemic index (GI) of steamed bread was lower, which could reduce fasting blood glucose and glycated serum protein by 21.55% and 26.11%, respectively, and could significantly improve oral glucose tolerance and blood lipid levels in diabetic mice, and had a certain protective effect on liver injury. These findings provide a scientific basis for the development of functional foods. © 2024, The Authors. All rights reserved.

Antimicrobial resistance has gained increasing attention since the awareness of its potential health risks. In this study, ultraviolet light emitting-diode (UV-LED) at two different wavelengths, i.e., 265 and 285 nm, were applied to irradiate an Escherichia coli strain carrying multiple resistance independently or combined. Inactivation, photoreactivation, cell membrane integrity, metabolic activity, and ARG removal were assessed. It was commonly revealed that the inactivation efficiency of E. coli strain measured by cultivability had approximately 5-log after 30 min irradiation, and the photoreactivation was suppressed to less than 1% during storage among all the three conditions. Flow cytometry showed obviously intermediate region between "live" and "dead" population, indicating a process of intact cells developed to slightly damaged cells and then to severely damaged cells, especially in the condition of 265/285 nm UV-LED. However, ATP and esterase activity seemed not in consistent with cell structural damage. Furthermore, 265/285 nm UV-LED performed significantly ARG removal, referring to 3.65, 5.05, and 3.19 log removal for tet A , cat 1 , and amp C , respectively. Overall, the combination of 265 nm UV-LED and 285 nm UV-LED can be a promising method for ARG control in water. © 2022, The Authors. All rights reserved.

Developing S-scheme photocatalysts with excellent catalytic activity and convenient retrieval is highly desirable for wastewater purification. Herein, a novel S-scheme MIL-101(Fe)/WO3 heterojunction on carbon cloth is successfully synthesized via a facile solvothermal approach. The optimized MIL-101(Fe)/WO3 composite (MWC-1.5) has been found to be highly effective in activating peroxymonosulfate (PMS) and then degrading tetracycline hydrochloride (TC-HCl) with a 100% degradation rate when exposed to visible light (Vis) within a period of 20 minutes. Such MWC-1.5/PMS/Light system also shows a stable cycling performance and good recyclability. The remarkable photocatalytic degradation performance is mainly attributed to the powerful intrinsic electric field that accelerates the separation of photogenerated charge carriers via the S-scheme charge transfer. Radical quenching experiments and electron paramagnetic resonance (EPR) results suggest that ·SO4- and ·OH- are the major oxidizing substances in the photocatalytic processes. Three potential degradation pathways are deduced based on an in-depth analysis of the degradation intermediates and the degradation mechanism is also elucidated through a rational combination of the experimental studies and theoretical calculations. This novel hybrid photocatalyst system has been shown to be a promising strategy for environmental remediation, while also suggesting a feasible approach for the development of photocatalysts with both remarkable activity and stability. © 2024, The Authors.

With the rapid increase of sludge production from sewage treatment plants, the treatment of sludge drying condensate rich in a large amount of pollutants urgently needs to be addressed. Due to the unique characteristics of sludge drying condensate (high ammonia nitrogen and COD concentration), there are almost no reports on biological treatment methods specifically targeting sludge drying condensate. In this study, A/O-MBR process was proposed for sludge drying condensate treatment and the effects of ammonia nitrogen loads, alkalinity and aeration intensity were explored. Experimental results show that under the ammonia nitrogen load of 0.35 kg NH4+-N/(m3·d) and the aeration intensity of 0.5 m3/(m2·min), the removal rate of COD and NH4+-N could reach 94% and 99.86% with the addition of alkalinity (m(NaHCO3): m(NH4+-N) = 7:1), respectively. The distribution of living and dead microbial cells in the activated sludge of three reactors also proved that the supplement of alkalinity in the influent can ensure the feasible living conditions for microorganisms. In addition to traditional nitrifying bacteria, through the supplementation of alkalinity and the reduction of aeration intensity, the system had also domesticated high abundance heterogeneous nitrification aerobic denitrification (HN-AD) and aerobic denitrification bacteria (both more than 10% of the total bacterial count). The denitrification process of sludge drying condensate was simplified and the denitrification efficiency was greatly improved. The findings of this study could provide important theoretical guidance for the biological treatment process of sludge drying condensate. © 2023 Elsevier Ltd

Electrocatalysts with densely exposed sites and high intrinsic activity are desired for high-efficiency oxygen evolution reaction (OER). In this paper, we report the microwave assisted solvothermal growth of NiMoO4 nanoflowers on electrodeposited Ni(OH)2 nanosheets, forming a high specific surface area (132.5 m2g-1) nanoflower-like NiMoO4/Ni(OH)2 configuration supported on a conductive nickel foam (NF) substrate. The as-prepared NiMoO4/Ni(OH)2/NF behaved efficiently as a self-supported 3D catalyst electrode for alkaline OER, compared with commercial RuO2 (298 mV overpotential at 10 mA cm-2 and Tafel slope of 84.3 mV dec-1), needing a low overpotential of 292 mV to attain 10 mA cm-2, with a small Tafel slope of 81.0 mV dec-1 and good stability for 10 h running at 10 mA cm-2 in 1.0 M KOH. Aside from enlarged surface area for more exposed edge sites for catalysis, the modulated synergy between Ni and Mo atoms probably contributes to enhanced intrinsic activity. A more electronegative Mo increases the electron density of Ni, thus accelerating the deprotonation of intermediates and driving the transition from Ni to NiOOH, leading to modulated thermodynamics and kinetics for OER catalysis. © 2023, The Authors.

Iron (Fe) migration in soil-plants is a critical part of Fe biogeochemical cycling in the earth surface system. Fe isotope fractionation analysis in the soil-rice system is promising for quantitatively assessing various pathways and clarifying Fe transformation processes. However, the mechanisms of Fe isotope fractionation in the soil-rice system are not well understood. In this study, the Fe isotopic compositions (δ^(56)Fe) of rhizosphere soils, pore water, Fe plaque, and rice plant tissues at the jointing and mature stages of the plants were determined. The rice plants were slightly enriched in heavier δ^(56)Fe by 0.3‰ relative to the soil, and the stele and cortex showed similar δ^(56)Fe values, indicating that the uptake of Fe by rice plants predominantly occurred via Fe(III)-phytosiderophores (Fe(III)-PS) chelation, but not Fe(III) reduction. Additionally, at both the jointing and mature stages, the rice plant tissues showed similar δ^(56)Fe values. However, the Fe isotope fractionation between the roots and stems (Δ56Feroot−stem) was 1.39 ± 0.13‰, which is similar to the previously Ab initio-calculated values between Fe(III)-citrate and Fe(III)- 2-deoxymugineic acid (DMA), indicating that both the phloem and xylem have similar δ^(56)Fe values, and the major Fe-chelating substances in the phloem of the rice plants are Fe(III)-DMA and Fe(II)- Nicotianamine (NA). Therefore, this study demonstrates that Fe isotope fractionation can be used as a signature for interpreting the Fe uptake and translocation mechanism in the soil-rice system.
