文摘The development of efficient,cost-effective electrocatalysts for oxygen evolution reaction(OER)is crucial for advancing sustainable energy.In this study,we investigated the influence of the solvent type on the morphological evolution and electrocatalytic performance of cobalt-based ZIF-67 metal-organic frameworks(MOFs).Particularly,we demonstrated the significant effect of solvent-mediated morphological control on the OER performance using methanol(MeOH),N,N-dimethylformamide(DMF),and deionized(DI)water.The ZIF-L(W),synthesized in DI water,exhibited a unique 2D leaf-like structure,and achieved remarkably low overpotentials of 360,398,and 460 mV at current densities of 50,100,and 200 mA cm^(−2),respectively.This performance significantly surpasses those of the polyhedral ZIF-67(D)and ZIF-67(M)structures synthesized in DMF and MeOH,respectively.The superior OER activity of ZIF-L(W)was attributed to its larger pore size,enhanced electron transfer properties,and the formation of unsaturated coordination sites.These results present a scalable,low-temperature route for designing high-performance MOF-based electrocatalysts with potential applications in sustainable energy systems.
文摘Objective:To explore the application effect of the path for improving humanistic literacy of operating room nursing students based on the ORTCC model,in order to make up for the deficiency of systematic humanistic education in the traditional teaching model.Methods:120 nursing students who practiced in the operating room from June 2023 to June 2024 were randomly divided into the experimental group and the control group,with 60 students in each group.The control group received routine teaching,while the experimental group applied the ORTCC model on the basis of routine and intervened through setting humanistic literacy goals,formulating behavioral norms,conducting diversified training,implementing two-way assessment,and creating departmental culture.The effect of the intervention was evaluated using the Nurse Humanistic Quality Scale,the Clinical Communication Ability Assessment Scale for Operating Room Nursing Students,and a self-made nursing satisfaction questionnaire.Results:After the intervention,the total score of humanistic literacy in the experimental group(4 weeks of intervention:161.43±10.06 points,12 weeks of intervention:165.71±9.45 points)was significantly higher than that in the control group(139.38±10.95 points,143.31±10.52 points)(all p<0.001);The total score of clinical communication ability in the experimental group(109.69±8.05 points for 4 weeks of intervention,116.90±7.21 points for 12 weeks of intervention)was also significantly better than that in the control group(99.14±9.23 points,103.03±8.78 points)(all p<0.001);The total score of patient care satisfaction in the experimental group(94.2±4.3)was significantly higher than that in the control group(82.6±5.7)(p<0.001).Conclusion:The ORTCC model can systematically enhance the humanistic literacy,clinical communication skills and patient satisfaction of operating room nursing students,providing an effective approach for optimizing clinical teaching in the operating room.

文摘Thermocatalytic biofuel production via(trans)esterification can be highly enabled by solid alkali catalysts,while often suffering from serious saponification and unsatisfactory catalyst reusability when the bases are directly used for high-acid-value oils.Herein,room temperature single-step upgrading of various non-edible oils(acid values:66-21.5 mgKOHg^(-1))to biodiesel(>97%yields)after 37 min with satisfactory fuel properties was achieved under solar irradiation over a renewable heterogeneous Lewis base catalyst(Cs/GL-4),which was composed of adjacent Cs single atoms(ACs SA)anchored on graphene-like(GL)biomaterial.Infrared thermal imaging showed that Cs/GL-4 had good photothermal performance,while quantum calculations and COMSOL multiphysics disclosed that ACs S A exhibited the prominent pyroelectric effect which was closely correlated with super-alkalinity and good acid resistance,both contributing to rapidly producing biodiesel of high efficiency under ambient conditions(25℃).Moreover,the pronounced activity and reusability of Cs/GL-4 were verified by reaction kinetics and recycling studies.The life cycle assessment indicated significant advantages in terms of energy savings(68.86 MJ kg^(-1))and negative carbon emission(-2.42 kg_(CO_(2eq))kg^(-1))associated with the photothermaldriven protocol for renewable diesel production,suggesting its relatively positive overall environmental impact.The electronic structure of adjacent atomic sites further enhanced by the photothermal effect provides an alternative reference for the one-step and mild upgrading of raw biomass.

文摘Stimulus-responsive organic room temperature phosphorescent(RTP)materials have received significant attention in bioimaging,sensing,and data storage because of their controllable dynamic variability and rapid response.Organic cocrystals,with tailor-designed optical properties through manipulation of their aggregate structures,have proven to be very effective in elucidating the structureproperty relationship of organic RTP materials at the molecular level.Therefore,enhancing RTP through rigid frameworks that promote intersystem crossing is a valid approach.Notably,the realization of organic RTP co-crystal performance by altering the components or adjusting the crystal lattices is highly appealing;however,this has not been fully addressed.In this study,an organic RTP cocrystal,4,40-bipyridine(44BD),was employed as the host,and 1,4-diiodotetrafluorobenzene(DITF)and 4-bromo-2,3,5,6-tetrafluorobenzoic acid(TFBA)were employed as vips.The 44BD-DITF co-crystal exhibited an orange RTP,whereas 44BD-TFBA displayed a bright yellow RTP.Crystal analysis and theoretical calculations revealed that dense molecular packing and abundant intermolecular interactions within these co-crystals are crucial for the emergence of RTP.Notably,both co-crystals show a reversible acid/base stimulus response,that is,exposure to hydrochloric acid(HCl)fumes results in quenching of their RTP,which can be subsequently restored by triethylamine(TEA)fumigation.This study presents an effective approach towards reversible RTP switching in organic co-crystals,thus offering opportunities for the development of acid/base stimulus-responsive materials for next-generation applications.

文摘Traditional resistive semiconductor gas sensors suffer from high operating temperatures and poor selectivity.Thus,to address these issues,a highly selective nitrogen dioxide(NO_(2))sensor based on lead sulfide(PbS)quantum dots(QDs)–lead molybdate(PbMoO_(4))–molybdenum disulfide(MoS_(2))ternary nanocomposites operating at room temperature was fabricated herein.The ternary nanocomposites were synthesized using an in situ method,yielding Pb S QDs with an average size of~10 nm and PbMoO_(4)nanoparticles in the 10-to 20-nm range,uniformly distributed on ultrathin MoS_(2)nanosheets with an average thickness of~7 nm.The optimized sensor demonstrated a significant improvement in response to 1 ppm NO_(2)at 25℃,achieving a response of 44.5%,which was approximately five times higher than that of the pure MoS_(2)-based sensor(8.5%).The sensor also achieved relatively short response/recovery times and full recovery properties.Notably,the optimal sensor displayed extraordinary selectivity toward NO_(2),showing negligible responses to different interfering gases.Density functional theory(DFT)calculations were conducted to elucidate the underlying sensing mechanism,which was attributed to the enhanced specific surface area,the receptor function of both PbS QDs and PbMoO_(4)nanoparticles,and the transducer function of MoS_(2) nanosheets.

文摘Solid-state batteries(SSBs)with thermal stable solid-state electrolytes(SSEs)show intrinsic capacity and great potential in energy density improvement.SSEs play critical role,however,their low ionic conductivity at room temperature and high brittleness hinder their further development.In this paper,polypropylene(PP)-polyvinylidene fluoride(PVDF)-Li_(1.3)Al_(0.3)Ti_(1.7)(PO_(4))_(3)(LATP)-Lithium bis(trifluoromethane sulphonyl)imide(LiTFSI)multi-layered composite solid electrolyte(CSE)is prepared by a simple separator coating strategy.The incorporation of LATP nanoparticle fillers and high concentration LiTFSI not only reduces the crystallinity of PVDF,but also forms a solvation structure,which contributes to high ionic conductivity in a wide temperature.In addition,using a PP separator as the supporting film,the mechanical strength of the electrolyte was improved and the growth of lithium dendrites are effectively inhibited.The results show that the CSE prepared in this paper has a high ionic conductivity of 6.38×10^(-4)S/cm at room temperature and significantly improves the mechanical properties,the tensile strength reaches 11.02 MPa.The cycle time of Li/Li symmetric cell assembled by CSE at room temperature can exceed 800 h.The Li/LFP full cell can cycle over 800 cycles and the specific capacity of Li/LFP full cell can still reach 120 m Ah/g after 800 cycles at 2 C.This CSE has good cycle stability and excellent mechanical strength at room temperature,which provides an effective method to improve the performance of solid electrolytes under moderate condition.

文摘Objective The lack of clarity regarding the application performance of a hybrid operating room(HOR)and the uncertainty of surgical scheduling often lead to its inefficient application.This study aimed to review the clinical application of our neurosurgical HOR and propose a scale to score cases clearly.Methods We reviewed the operating procedures and duration of stay in 1865 HOR cases.The actual procedures of each case were summarized into 5 application types,and numerical assignment was used to distinguish the dependence of each type on our HOR:surgical procedures combined with interventional procedures(4 points,the highest dependence),surgical procedures combined with imaging procedures(3 points),interventional procedures(2 points),imaging procedures(1 point),and surgical procedures(0 points,the lowest dependence).Results A novel scale that could score 1865 cases into those 5 grades was developed.The percentages by grade were as follows:4 points,4.24%;3 points,4.88%;2 points,20.75%;1 point,69.38%;and 0 points,0.75%.The cumulative usage time was 4241.9 h,the duration of which was as follows:4 points,16.17%;3 points,15.50%;2 points,31.32%;1 point,35.62%;and 0 points,1.39%.Conclusions The HOR serves as a multifunctional room to treat neurosurgical diseases.The scale helps to quickly prioritize cases that rely more on HOR,providing guidelines for surgical scheduling.Although our HOR is unsuitable for emergency cases,it clearly shows the application performance of our HOR to provide a reference for promoting its efficient application.
文摘The Healthcare Failure Mode and Effect Analysis(HFMEA)model,as a proactive risk assessment tool,systematically identifies potential infection risk points during surgical procedures and evaluates the failure modes and their effects that may result from these risks.Evidence-based medicine,on the other hand,emphasizes making medical decisions based on the best available evidence.Combining these two approaches can provide more scientific and effective strategies for preventing infection in operating rooms.This paper delves into the application of the HFMEA model and evidence-based medicine in the field of infection prevention in operating rooms,aiming to offer new perspectives and methods for this critical aspect of healthcare.

文摘In recent years,research on nursing interruptions has been conducted at various levels in emergency departments,intensive care units,hemodialysis centers,operating rooms,and sterilization and supply centers.Nursing interruptions are closely related to adverse nursing events,and interruptions in operating room nursing can significantly impact the success of a patient’s surgery.However,there is a lack of in-depth theoretical research on safety risk assessment and response decision-making by operating room nurses when faced with nursing interruptions.This article reviews the concept,current status,and impact of nursing interruptions in the operating room,analyzes the cognitive level,coping strategies,and negative emotions of operating room nurses,and elaborates on management strategies to provide references for research and management of nursing interruptions in the operating room.
文摘Refractory high-entropy alloys(RHEAs),composed of multiple refractory elements,such as Nb,Mo,Ta,W,Ti,Zr,Hf,in nearor non-equiatomic ratios,have recently emerged as promising structural materials for extreme environments due to their high melting points,excellent high-temperature mechanical properties,and superior micro structural stability.Compared to conventional HEAs based on elements like Ni,Fe,or Cr,RHEAs offer enhanced elevated-temperature performance but face challenges including segregation during solidification,relatively poor room-temperature ductility,and,most important,high-temperature oxidation.
