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Background There is a growing focus on using various plant-derived agricultural by-products to increase the benefits of pig farming,but these feedstuffs are fibrous in nature.This study investigated the relationship between dietary fiber physicochemical properties and feedstuff fermentation characteristics and their effects on nutrient utilization,energy metabolism,and gut microbiota in growing pigs.Methods Thirty-six growing barrows(47.2±1.5 kg)were randomly allotted to 6 dietary treatments with 2 apparent viscosity levels and 3β-glucan-to-arabinoxylan ratios.In the experiment,nutrient utilization,energy metabolism,fecal microbial community,and production and absorption of short-chain fatty acid(SCFA)of pigs were investigated.In vitro digestion and fermentation models were used to compare the fermentation characteristics of feedstuffs and ileal digesta in the pig’s hindgut.Results The production dynamics of SCFA and dry matter corrected gas production of different feedstuffs during in vitro fermentation were different and closely related to the physical properties and chemical structure of the fiber.In animal experiments,increasing the dietary apparent viscosity and theβ-glucan-to-arabinoxylan ratios both increased the apparent ileal digestibility(AID),apparent total tract digestibility(ATTD),and hindgut digestibility of fiber components while decreasing the AID and ATTD of dry matter and organic matter(P<0.05).In addition,increasing dietary apparent viscosity andβ-glucan-to-arabinoxylan ratios both increased gas exchange,heat production,and protein oxidation,and decreased energy deposition(P<0.05).The dietary apparent viscosity andβ-glucanto-arabinoxylan ratios had linear interaction effects on the digestible energy,metabolizable energy,retained energy(RE),and net energy(NE)of the diets(P<0.05).At the same time,the increase of dietary apparent viscosity andβ-glucan-to-arabinoxylan ratios both increased SCFA production and absorption(P<0.05).Increasing the dietary apparent viscosity andβ-glucan-to-arabinoxylan ratios increased the diversity and abundance of bacteria(P<0.05)and the relative abundance of beneficial bacteria.Furthermore,increasing the dietaryβ-glucan-to-arabinoxylan ratios led to a linear increase in SCFA production during the in vitro fermentation of ileal digesta(P<0.001).Finally,the prediction equations for RE and NE were established.Conclusion Dietary fiber physicochemical properties alter dietary fermentation patterns and regulate nutrient utilization,energy metabolism,and pig gut microbiota composition and metabolites.

文摘CO_(2)-responsive gels,which swell upon contact with CO_(2),are widely used for profile control to plug high-permeability gas flow channels in carbon capture,utilization,and storage(CCUS)applications in oil reser-voirs.However,the use of these gels in high-temperature CCUS applications is limited due to their rever-sible swelling behavior at elevated temperatures.In this study,a novel dispersed particle gel(DPG)suspension is developed for high-temperature profile control in CCUS applications.First,we synthesize a double-network hydrogel consisting of a crosslinked polyacrylamide(PAAm)network and a crosslinked sodium alginate(SA)network.The hydrogel is then sheared in water to form a pre-prepared DPG suspen-sion.To enhance its performance,the gel particles are modified by introducing potassium methylsilan-etriolate(PMS)upon CO_(2) exposure.Comparing the particle size distributions of the modified and pre-prepared DPG suspension reveals a significant swelling of gel particles,over twice their original size.Moreover,subjecting the new DPG suspension to a 100℃ environment for 24 h demonstrates that its gel particle sizes do not decrease,confirming irreversible swelling,which is a significant advantage over the traditional CO_(2)-responsive gels.Thermogravimetric analysis further indicates improved thermal sta-bility compared to the pre-prepared DPG particles.Core flooding experiments show that the new DPG suspension achieves a high plugging efficiency of 95.3%in plugging an ultra-high permeability sandpack,whereas the pre-prepared DPG suspension achieves only 82.8%.With its high swelling ratio,irreversible swelling at high temperatures,enhanced thermal stability,and superior plugging performance,the newly developed DPG suspension in this work presents a highly promising solution for profile control in high-temperature CCUS applications.

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Global climate change has become one of the most pressing challenges of the 21st century.As anthropogenic CO_(2) emissions from fossil fuel consumption and industrial processes continue to disrupt Earth’s carbon cycle,atmospheric CO_(2) concentrations have reached unprecedented levels-exceeding 420 parts per million(ppm)in 2023 compared to pre-industrial 280 ppm.This rapid accumulation of greenhouse gases has resulted in measurable con-sequences including rising global temperatures,ocean acidifica-tion,and increased frequency of extreme weather events.
文摘Objectives:This scoping review aims to methodically identify and analyse the determinants which influence maternal mortality and healthcare utilization in women of childbearing years in Nigeria.The review specifically addresses the difficulties faced in assessing medical care,and the ongoing initiatives to lower the maternal mortality ratio.Methods:Primary studies(published after year 2000)focused on maternal mortality,health determinants,and the utilization of maternal healthcare services in Nigeria were retrieved following a systematic search across multiple databases,including Scopus,PubMed,Google Scholar,and Web of Science.These were screened using defined inclusion and exclusion criteria.Data from these studies were extracted and thematically analysed to identify common themes and trends.Results:A total of 21 publications were included in this review comprising 2 qualitative,17 quantitative,and2 mixed study designs.Major health determinants identified in these studies include hypertensive disorders of pregnancy,haemorrhage,and sepsis/septicaemia,contributing as much as 29%,24%,and 14.2%of maternal deaths respectively in over 10%of the reviewed studies.Similarly,social-economic determinants including poverty,maternal education,health system issues and culture significantly impacted the utilization of maternal healthcare services,inadvertently impacting maternal mortality.Despite various maternal health interventions such as the"Abiye"Safe Motherhood Initiative,the Integrated Maternal,Newborn,and Child Health Strategy and strengthening emergency obstetric care by governmental and non-governmental agencies,early childbearing,unemployment,large family sizes,and dependence on male spouses continued to result in suboptimal utilization of services and adverse maternal outcomes.Conclusion:This scoping review comprehensively integrated existing data from published studies to provide a detailed picture of maternal mortality,its health determinants,and factors influencing care utilization among women of childbearing age in Nigeria and approaches to reduce maternal mortality in the country and possibly in the West African sub-region.
