However, the limited utilization of biomass majorly focused on cellulose and hemicellulose restricts the economic and environmental feasibilities. To cope with this issue, we proposed an integrated process of co-producing 1,6-hexanediol(1,6-HDO) with tetrahydrofuran and adipic acid from biomass, referred to as Strategy A. To compare the impacts of lignin upgrading and feedstock, Strategy B, which co-produces tetrahydrofuran alone, and Strategy C, which is the traditional route to produce 1,6-HDO from fossil fuels, were used. Heat networks are also designed to reduce operating costs and indirect carbon emissions due to energy consumption, saving 87% and 83% of the heat and cooling requirements, respectively, in Strategy A. The market competitiveness of Strategy A was evaluated by determining the minimum selling price through techno-economic analysis, and sustainability was thoroughly investigated by quantifying the environmental impacts through both midpoint and endpoint life-cycle assessments(LCAs).Strategy A was found to be the most favorable both economically(USRDSCHARDOLLAR3,402/ton) and environmentally(-26.9 kg CO_(2)eq.). This indicates that lignin valorization is not only economically but also environmentally preferred. Finally, changes in economic and environmental feasibilities depending on economic, process, and environmental parameters were investigated using sensitivity and uncertainty analyses. The results of these analyses provide valuable insight into bio-based chemical production.展开更多

文摘Tantalum nitride is widely considered as a promising photoanode material for its suitable band structure as well as the high theoretical conversion efficiency in solar water splitting.However,it is limited to inefficient photoinduced electron–hole pair separation and interfacial dynamics in the photoelectrochemical oxygen evolution reaction.Herein,multiple layers including Ti_(x)Si_(y) and NiFeCoO_(x) were fabricated based on band engineering to regulate tandem electric states for efficient transfer of energy carriers.Besides,photothermal local surface plasmon resonance was introduced to accelerate the kinetics of photoelectrochemical reactions at the interface when the special Ag nanoparticles were loaded to extend the absorbance to near infrared light.Consequently,a recordable photocurrent density of 12.73 mA cm^(-2) has been achieved at 1.23 V versus RHE,approaching a theoretical limit of the tantalum nitride photoanode with full-spectrum solar utilization.Meanwhile,compared to the applied bias photon-to-current efficiency of 1.36%without photothermal factor,a high applied bias photonto-current efficiency of 2.27%could be raised by applying local surface plasmon resonance to photoelectrochemical oxygen evolution reaction.The efficient design could maximize the use of solar light via the classification of spectrum and,therefore,may spark more innovative ideas for the future design and development of the next-generation photoelectrode.
文摘BACKGROUND There is increasing incidence of alcohol-associated liver disease in females.Despite this recent increased incidence,there is a paucity of research on the clinical course and outcomes of alcohol-associated hepatitis(AH)in females compared to males.AIM To assess if there may be sex differences in severity,outcomes,and healthcare utilization for patients hospitalized for AH.METHODS This study used ICD-9-CM and ICD-10-CM codes to retrospectively identify inpatient encounters for AH at the University of Kentucky from 2012-2021 and obtained data on patient demographics and clinical outcomes.Encounters were cohorted by patient sex and differences in patient demographics and clinical outcomes were assessed.Multivariate logistic regression models were constructed to assess risk of mortality,sepsis,and mechanical ventilation during the encounter.RESULTS Of 1386 subjects,511(36.9%)were female and 875(63.1%)were male.Both sexes had similar baseline characteristics of race/ethnicity,discriminant function score,model of end-stage liver disease score,and length of hospital stay.However,the incidence of urinary tract infection,sepsis,and norepinephrine administration was significantly higher for females.Males had a significantly higher incidence of esophageal variceal bleed.On multivariate logistic regression analysis,females had higher odds of encounter sepsis(OR 1.41;95%CI:1.064-1.869)and mechanical ventilation(OR 1.352;95%CI:1.006-1.816).Odds of encounter mortality were significantly increased in encounters with sepsis(OR 2.309;95%CI:1.419-3.757)and mechanical ventilation(OR 9.301;95%CI:5.724-15.114).CONCLUSION This study shows sex-based differences in AH outcomes at the University of Kentucky.Future studies are warranted to assess whether tailoring treatments will improve clinical outcomes in females with AH.

文摘Lignocellulosic biomass is one of the viable solutions to alleviate the global warming. However, the limited utilization of biomass majorly focused on cellulose and hemicellulose restricts the economic and environmental feasibilities. To cope with this issue, we proposed an integrated process of co-producing 1,6-hexanediol(1,6-HDO) with tetrahydrofuran and adipic acid from biomass, referred to as Strategy A. To compare the impacts of lignin upgrading and feedstock, Strategy B, which co-produces tetrahydrofuran alone, and Strategy C, which is the traditional route to produce 1,6-HDO from fossil fuels, were used. Heat networks are also designed to reduce operating costs and indirect carbon emissions due to energy consumption, saving 87% and 83% of the heat and cooling requirements, respectively, in Strategy A. The market competitiveness of Strategy A was evaluated by determining the minimum selling price through techno-economic analysis, and sustainability was thoroughly investigated by quantifying the environmental impacts through both midpoint and endpoint life-cycle assessments(LCAs).Strategy A was found to be the most favorable both economically(USRDSCHARDOLLAR3,402/ton) and environmentally(-26.9 kg CO_(2)eq.). This indicates that lignin valorization is not only economically but also environmentally preferred. Finally, changes in economic and environmental feasibilities depending on economic, process, and environmental parameters were investigated using sensitivity and uncertainty analyses. The results of these analyses provide valuable insight into bio-based chemical production.

文摘Understanding livestock performance in typical steppe ecosystems is essential for optimizing grassland-livestock interactions and minimizing environmental impact.To assess the effects of different stocking rates on the growth performance,energy and nitrogen utilization,methane(CH_(4))emissions,and grazing behavior of Tan sheep,a 2-year grazing experiment in the typical steppe was conducted.The grazing area was divided into 9 paddocks,each 0.5 ha,with 3 spatial replicates for each stocking rate treatment(4,8,and 13 sheep per paddock),corresponding to 2.7,5.3,and 8.7 sheep ha^(–1).The results showed that the neutral detergent fiber(NDF)and acid detergent fiber(ADF)contents of herbage varied between grazing years(P<0.05),with a positive correlation between stocking rate and crude fiber content in the herbage(P<0.05).Dry matter intake(DMI)decreased with increasing stocking rate(P<0.05),and the average daily gain(ADG)was highest at 2.7 sheep ha^(–1)(P<0.05).Compared to 2.7 and 8.7 sheep ha^(–1),the5.3 sheep ha^(–1)treatment exhibited the lowest nutrient digestibility for dry matter,nitrogen,and ether extract(P<0.05).Fecal nitrogen was lowest at 8.7 sheep ha^(–1)(P<0.05),while retained nitrogen as a proportion of nitrogen intake was highest.Digestive energy(DE),metabolic energy(ME),and the ratios of DE to gross energy(GE)and ME to GE were highest at 8.7 sheep ha^(–1)(P<0.05).In contrast,CH_4 emissions,CH_4 per DMI,and CH_(4)E as a proportion of GE were highest at 2.7 sheep ha^(–1)(P<0.05).Stocking rate and grazing year did not significantly affect rumen fermentation parameters,including volatile fatty acids,acetate,propionate,and the acetate/propionate ratio.At 8.7sheep ha^(–1),daily grazing time and inter-individual distance increased,while time allocated to grazing,walking,and ruminating/resting decreased as stocking rates increased(P<0.05).This study highlights the importance of adjusting stocking rates based on the nutritional value of forage and grazing year to optimize grazing management.

文摘BACKGROUND Adolescence is a period marked by physiological and psychological imbalances,which pose an increased risk for adolescents with major depressive disorder(MDD)to commit non-suicidal self-injury(NSSI).AIM To investigate the moderating role of social support utilization in depression and NSSI among adolescents with MDD.METHODS This cross-sectional study enrolled 314 adolescents with MDD(258 with NSSI,56 without)from a Chinese tertiary psychiatric hospital(2021-2023).Participants completed validated scales,including the self-esteem scale,the Barratt impulsiveness scale,the self-rating depression scale,and the teenager social support rating scale.Logistic regression and hierarchical regression analyses were used to examine predictors of NSSI and the moderating effect of social support utilization.RESULTS Results showed that the NSSI group had higher depression levels,lower selfesteem,and greater impulsivity.While overall social support was higher in the NSSI group,social support utilization significantly moderated the depression-NSSI relationship.Specifically,higher utilization levels weakened the association between depression and NSSI(β=-0.001,P<0.05).CONCLUSION These findings suggest that effective utilization of social support,rather than its mere presence,is crucial in reducing NSSI risk among depressed adolescents.
