文摘Green transplant refers to the realization of the importance of understanding and improving the environmental footprint of transplantation through sustainable practices.This involves assessing the entire transplantation process including preoperative evaluation,donation,organ and patient transportation,surgery,postoperative recovery,and follow-up.This is a topic that has not been fully addressed yet,but its importance is being increasingly appreciated in surgery.The aim of this study was to investigate the carbon footprint associated with transplantation and propose sustainable mitigating solutions.A comprehensive review of the existing literature on transplantation was conducted and supplemented with findings from the broader fields of surgical and perioperative care,given the scarcity of available data.The analysis identified the most involved environmental factors and attempted to offer practical solutions based on current sustainability practices.Notably,no study has yet examined the carbon footprint associated with the entire transplantation procedure.Only five studies have attempted to assess the environmental impact of kidney or liver transplants,but they focused,almost explicitly,on specific steps of the process.By employing an extrapolative methodology from the broader surgical field,we determined that the primary contributors to the environmental impact of transplantation are energy,consumables and materials,anesthesia and pharmaceuticals,transportation,and water.This review offers practical solutions utilizing the 5R framework,emphasizing sustainability to ensure transplantation remains clinically and environmentally relevant.

文摘Local Climate Zones(LCZs)provide a standardized framework for analyzing urban thermal environment.Examining the interactive effects of building and green space patterns on land surface temperature(LST)within LCZs is essential for uncovering urban cooling mechanisms and developing strategies for heat-mitigation urban design.Therefore,this study employed one-way ANOVA and Duncan's multiple comparison to test compare the significant differences of LST among LCZs 1-6,and applied the XGBoost model to quantify the interactive effects of building and green space indicators on LST,and to identify the threshold ranges of their cooling effects.The results showed that LCZ 2 exhibited the highest LST,while LCZ 4 recorded the lowest.Average building volume(BAV),building coverage ratio(BCR),green cover area(GCA),and the total edge length of green space(GTE)were identified as the key indicators driving the interactive effects on LST.In LCZ 2,when BAV exceeded 1800 m^(3),the interaction of higher GCA and GTE contributed to lower LST.When BCR was less than 0.6 in LCZs 4-5,lower GCA and GTE values enhanced the LST reduction.The results provided a strategic basis for urban thermal environment mitigation and sustainable development under the LCZ framework.

文摘Atrazine,a persistent triazine herbicide,poses environmental and health risks.This study examines the synergis-tic remediation of atrazine-contaminated soil using green manure plant(GMP)hairy vetch(Vicia villosa Roth,VV)and the exogenous atrazine-degrading bacterium Arthrobacter sp.ATR1.Soil samples contaminated with atrazine at 5 and 20 mg/kg were treated with control(CK),ATR1(CKatr),hairy vetch(VV),and combined hairy vetch and ATR1 remediation(VVatr).The results indicated that the VVatr treatment exhibited the most effective atrazine removal,achieving enhancements of 56.12%at 5 mg/kg and 54.51%at 20 mg/kg compared to CK after 28 days.Soil enzyme activities,including urease,sucrase,and alkaline phosphatase,were significantly elevated in the VV and VVatr treatments,contributing to improved soil quality.Additionally,the CKatr,VV,and VVatr treat-ments enhanced bacterial diversity and richness while altering the microbial community structure.The VV and VVatr treatments notably enriched indigenous atrazine-degrading bacteria and nitrogen-fixing bacteria in the rhizosphere.This microbial enrichment upregulated the Atrazine degradation and Nitrogen metabolism pathways,facilitating both atrazine removal and nitrogen cycling in the soil.And VVatr treatment promoted the stability of the microbial network and enhanced the cooperative relationship between key indigenous atrazine-degrading and nitrogen-fixing bacteria.These findings explain the mechanism of plantmicrobe combined remediation of atrazine-contaminated soil from the perspective of rhizosphere microorganisms and offer a theoretical basis for the practical application of this method.

文摘Trentepohliales is a completely terrestrial order within Ulvophyceae(the core Chlorophyta),and its closely related lineages are mainly marine macroalgae(green seaweeds).Despite the considerable interest in their biotechnological potential,little is known about their adaptations to challenging terrestrial habitats.Here,we assemble the high-quality reference genome of Trentepohlia odorata.This alga shows duplications of key genes associated with lipid metabolism and carotenoid synthesis,potentially facilitating intracellular accumulation of lipid droplets and carotenoids.We further reveal positive selection and expansion of gene families involved in vesicle trafficking and cell division regulation in T.odorata compared with other algae(cleavage furrow-mediated cell division)in Ulvophyceae,providing a genetic foundation for the evolution of phragmoplast-mediated cell division.The combined C_(4)-like and biophysical CO_(2)-concentrating mechanisms(CCMs)of T.odorata enable adaptation to fluctuating CO_(2) environments,and support efficient photosynthesis under CO_(2)-limited conditions.Adaptive strategies of T.odorata to terrestrial stressors,such as drought,intense light,and UV-B radiation,include horizontally acquired genes involved in cell wall synthesis and remodeling,homeostasis of aldehydes,and expanded genes associated with reactive oxygen species(ROS),DNA repair,and photoprotection.Our study provides a valuable genomic resource for studying aerial algae and improves understanding of plant terrestrialization.

文摘Cellulose frameworks have emerged as promising materials for light management due to their exceptional light-scattering capabilities and sustainable nature.Conventional biomass-derived cellulose frameworks face a fundamental trade-off between haze and transparency,coupled with impractical thicknesses(≥1 mm).Inspired by squid’s skin-peeling mechanism,this work develops a peroxyformic acid(HCOOOH)-enabled precision peeling strategy to isolate intact 10-μm-thick bamboo green(BG)frameworks—100×thinner than wood-based counterparts while achieving an unprecedented optical performance(88%haze with 80%transparency).This performance surpasses delignified biomass(transparency<40%at 1 mm)and matches engineered cellulose composites,yet requires no energy-intensive nanofibrillation.The preserved native cellulose I crystalline structure(64.76%crystallinity)and wax-coated uniaxial fibril alignment(Hermans factor:0.23)contribute to high mechanical strength(903 MPa modulus)and broadband light scattering.As a light-management layer in polycrystalline silicon solar cells,the BG framework boosts photoelectric conversion efficiency by 0.41%absolute(18.74%→19.15%),outperforming synthetic anti-reflective coatings.The work establishes a scalable,waste-to-wealth route for optical-grade cellulose materials in next-generation optoelectronics.

文摘The high hydrophilicity of pineapple leaf fibres(PALF)limits their use in cement-and gypsum-based composites exposed to moisture.This study evaluates,for the first time,the combined effect of palm kernel oil and beeswax on the hygroscopic resistance and mechanical stability of PALF.The fibres were functionalised with three formulations(oil,wax,and a 1:2 oil/wax blend)applied at different mass ratios(CR=0.5-2).Treatments increased the average bundle diameter by up to+46%(238μm)and reduced density down to 1.06 g/cm^(3).Hygroscopically,water absorption decreased from 202.4%(raw fibres)to 76.3%(CR=2),representing a maximum reduction of 59.4%in saline medium,while moisture regain dropped from 27.9%to 14.6%(−47.7%).The oil/wax blend proved most effective,simultaneously reducing water absorption(−51.2%)and moisture regain(−46.8%)at CR=1.Mechanically,the fibres retained tensile strength(415.2 vs.460.8 MPa,+11%at CR=1)and exhibited enhanced ductility(+62.5%,with elongation at break increasing from 1.6%to 2.6%),without significantly altering Young’s modulus(12.3 to 10 GPa).Water absorption kinetics were accurately described by the Czel and Mohsenin models(R^(2)>0.98).These findings clearly demonstrate that bio-based lipid coatings can provide an eco-friendly alternative to conventional chemical treatments.They improve hygroscopic resistance and preserve mechanical integrity of PALF,providing original quantitative data for their integration into durable cement-and gypsum-based composites subjected to humid or cyclic wet-dry conditions.

文摘Green manuring is essential for improving soil quality and nutrient uptake.With the gradual depletion of phosphorus(P)resources,more attention is being paid to the role of green manures in cultivation systems,such as maize-green manure intercropping,to find possible pathways for enhancing soil P utilization.A maize-green manure intercropping experiment was started in 2009 to investigate the effects and mechanisms for enhancing P uptake and yield in maize.Three species of green manures(hairy vetch(HV),needle leaf pea(NP),sweet pea(SP))and a sole maize treatment(CK)were used,resulting in four treatments(CK,HVT,NPT,and SPT)in the experiment.During 2020-2023,the intercropping treatments enhanced maize yields in 2020 and 2021,particularly in HVT with increases of 13.7%(1.96 t ha^(-1))and 13.0%(2.13 t ha^(-1))compared with CK,respectively.Grain P accumulation of maize was significantly higher in the intercropping treatments than CK in 2020,2021,and 2023,and with an average increase of 10.6%over the four years(5.2% for NPT,10.8% for SPT and 15.9% for HVT)compared with CK.Intercropping promoted maize growth with a greater root length density and a higher organic acid release rate.HVT changed the soil properties more dramatically than the other treatments,with increases in the acid phosphatase and alkaline phosphatase activities of 29.8 and 38.5%,respectively,in the topsoil(0-15 cm),while the soil p H was reduced by 0.37 units compared to CK(p H=8.44).Intercropping treatments facilitated the conversion of non-labile P to mod-labile P and stimulated the growth of soil bacteria in the topsoil.Compared with CK,the relative abundance of Gemmatimonadota,known for accumulating polyphosphate,and Actinobacteriota,a prominent source of bioactive compounds,increased significantly in the intercropping treatments,especially in HVT and SPT.A PLS-PM analysis showed that intercropping promoted soil P mobilization and the enrichment of beneficial bacteria by regulating maize root morphology and physiology.Our results highlight that maize-green manure intercropping optimizes root traits,soil properties and bacterial composition,which contribute to greater maize P uptake and yield,providing an effective strategy for sustainable crop production.

文摘Previous studies have shown that the Eocene oil shale sequences in the Green River Basin contain long-period astronomical age information.The fine-scale chronological characteristics of the oil shale laminae remain largely unexplored.We selected finely laminated oil shales formed in deep-water environments characterized by stable water column stratification as the primary focus of this study,using microscopy and micro-area X-ray fluorescence(μ-XRF)techniques.By integrating high-resolution elemental data with timeseries analysis,we identified significant periodic signals associated with solar activity(Hale and Schwabe cycles)and ENSO.The results indicate that the alternations of light and dark laminae in the Green River Formation oil shale correspond to alternating dry and wet climate regimes:the light laminae are dominated by carbonate minerals,reflecting drier and milder conditions,while the dark laminae are enriched in terrigenous clastics and organic matter,indicating periods of increased precipitation and warmer temperatures.The detected periodicities(23.5 years,13.3 years and 5.8 years)are highly consistent with modern observations,demonstrating that the lower Eocene Green River oil shale effectively records short-term solar activity and climate variability.Furthermore,our findings confirm that a persistent"permanent El Niño"state did not develop under Early Eocene greenhouse conditions,providing a refined chronological framework for highresolution paleoclimate studies during greenhouse intervals.

文摘Green ammonia,produced by harnessing renewable solar energy to split nitrogen,plays a pivotal role in both agricultural practices and forthcoming energy configurations,driving the sustainable development of human society with zero-carbon emissions.However,nitrogen photoreduction currently faces the challenges of poor activation ability and low yield,and it is still challenging to unravel the intertwined problems in this field and provide direction for its development due to the complex reaction mechanism and multidisciplinary aspects such as photochemistry,catalysis,interface science,and technology.This review focuses on capturing the latest advances in photocatalytic nitrogen-to-ammonia conversion,delving into fundamental principles regarding the process,efficient photocatalysts for practical ammonia synthesis,and well-designed catalytic environments.Besides,this article provides insightful guidelines for analyzing complicated reaction mechanisms and identifying key bottlenecks or specific rate-determining steps,such as reactant activation,interfacial reaction engineering,and hydrogen evolution side reactions.By integrating perspectives from atomic mechanisms,nanoscale photocatalysts,microscale interfacial engineering,and macroscale reaction system design,this review advances the development of nitrogen photoreduction from proof-of-concept discoveries to viable solar-to-chemical conversion technologies,while also providing a valuable entry point for researchers into this burgeoning field.

文摘Inclusive green growth(IGG)is a crucial pathway to high-quality economic development,with standardization serving as a key enabler.Standardization plays a critical role in reducing coordination costs and improving resource allocation efficiency by facilitating rule harmonization,factor integration,and collaborative governance.Examining IGG from a standardization perspective helps clarify the mechanisms through which economic,environmental,and social objectives can be jointly realized,and offers new insights into the institutionalized and sustainable pursuit of multiple development goals.However,how standardization promotes IGG by coordinating economic growth,environmental performance,and social equity remains insufficiently explored in the existing literature.Using panel data from 283 prefecture-level Chinese cities(2012-2021),this study treats the comprehensive standardization reform pilot as a quasi-natural experiment and applies a double machine-learning framework to test whether standardization promotes IGG.The analysis further explores the mediating roles of technological innovation,green finance,and employment quality,and examines heterogeneity across geographic location,resource endowment,industrial base,and city hierarchy.It also evaluates the regional coordination effects of standardization.Results show that standardization significantly advances IGG,though its impact varies by regional and structural characteristics.Standardization enhances IGG by strengthening innovation,expanding green finance,and improving job quality.Moreover,it helps bridge geographic divides,narrow interregional disparities,and enhance coordination.These findings offer empirical evidence for policymakers to design targeted standardization strategies that support sustainable and equitable urban development.
