文摘This study reports the development of a novel amino‐functionalized ionic liquid catalyst,namely 1‐butyl‐3‐methylimidazolium amino triazole([EMIM]ATZ),for the efficient and sustainable synthesis of ethyl methyl carbonate(EMC)via transesterification of dimethyl carbonate(DMC)and ethanol(C_(2)H_(5)OH)at room temperature.Addressing the limitations of conventional catalytic systems that require elevated temperatures(>75℃),[EMIM]ATZ achieves 62%DMC conversion and 56%EMC yield within 8 h under room temperature(25℃),while conventional ionic liquids([EMIM]Cl,[EMIM]BF_(4),[EMIM]PF_(6) etc.)showed almost no activity at room temperature.The catalyst's superior activity stems from its strong basicity(pH≈9.2)and enhanced CO_(2) absorption capacity(200 mg·g^(−)1),which synergistically activate C2H5OH and stabilize reaction intermediates.Structural characterization via FTIR and thermogravimetric analysis(TGA)confirmed the catalyst's thermal stability and recyclability,with no significant degradation observed over five reuse cycles(89%activity retention).In addition,the ionic liquid was also able to catalyze the synthesis of methyl propyl carbonate(PMC)and methyl butyl carbonate(BMC)at room temperature.
文摘Objective:To explore the application effectiveness of the“Six-Step”Scenario-Based Teaching Method in operating room nursing education.Methods:Seventy nursing students undergoing clinical training in the operating room of a certain hospital from January 2024 to June 2025 were selected.They were randomly divided into an observation group(n=35)and a control group(n=35)using a random number table.The control group received traditional“mentor-apprentice”on-the-job training,while the observation group underwent the“six-step”scenario-based teaching method.The two groups were compared on final assessment scores,comprehensive competency,surgical nursing emergency response ability,and teaching satisfaction indicators.Results:The observation group achieved significantly higher final assessment scores(85.54±5.05)than the control group(78.63±4.75);After instruction,the observation group scored significantly higher than the control group in:mastery of basic duties and procedures(4.22±0.30 vs.3.98±0.30),understanding of surgical nursing essentials(4.39±0.19 vs.3.98±0.30),proficiency in surgical assistance(4.11±0.33 vs.3.98±0.30),aseptic awareness(4.32±0.24 vs.3.98±0.30),risk awareness(4.22±0.17 vs.3.98±0.30),and occupational safety awareness(4.01±0.23 vs.3.98±0.30).(4.01±0.23),which were significantly higher than the control group’s scores(3.36±0.28),(3.14±0.27),(3.29±0.24),(3.53±0.36),(3.17±0.25),and(3.51±0.18),respectively.Students in the observation group scored significantly higher than the control group in emergency hands-on skills(24.53±1.85 points),surgical coordination skills(27.65±1.87 points),emergency coordination skills(25.34±1.83 points),and patient condition observation skills(24.34±1.79 points)were significantly higher than those of the control group(20.78±1.74 points,26.31±1.95 points,22.92±1.69 points,and 21.58±1.77 points,respectively).The satisfaction rate with operating room nursing education among students in the observation group(97.00%)was significantly higher than that in the control group(77.00%).All differences were statistically significant(p<0.05).Conclusion:The“Six-Step”Scenario-Based Teaching Method effectively enhances operating room students’mastery of theoretical knowledge,practical skills,and core comprehensive abilities,while significantly improving their teaching satisfaction.It warrants promotion and application in operating room nursing education.

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Objective:To explore the application of moderate and hypothermia control in patients undergoing cerebral hemangioma surgery.By adjusting the precise body temperature of the patients and controlling the changes,the intraoperative and postoperative risks can be reduced,thereby better promoting postoperative recovery.Methods:Thirty patients undergoing cerebral hemangioma surgery were randomly selected as the subjects.All the patients were inpatients in the neurology department between May 2023 and May 2024.The control group received traditional routine nursing management.For the patients in the experimental group,in addition to traditional nursing management,there was also moderate and hypothermia intervention.The body temperature was monitored at three points:the tympanic membrane,esophagus,and rectum.The body temperature was effectively monitored to make it fluctuate within a relatively ideal range.The postoperative recovery was paid attention to and monitored.Key monitoring will be conducted on the intraoperative body temperature changes,hemodynamic indicators of the patients,as well as the postoperative awakening time and neurological function recovery indicators of the patients.Results:Compared with the control group,the patients in the experimental group with moderate to low body temperature had relatively gentle body temperature curves and little fluctuation in body temperature.In terms of hemodynamics,patients in the experimental group were more stable than those in the control group.Meanwhile,they recovered faster after the operation,the time required for patients to regain consciousness was shortened,and the incidence of postoperative complications was lower,especially infection,cerebral edema,and electrolyte abnormalities were more prominent.The comfort level and satisfaction of patients were relatively higher compared with those in the control group.Therefore,it can play a very good promoting role for the patient in the postoperative recovery.Conclusion:The application of moderate and low body temperature in cerebral hemangioma surgery can better stabilize the patient’s condition,reduce the occurrence of complications,and is conducive to the recovery of the patient’s neurological function.This method has changed the deficiency of body temperature management in traditional nursing and created a more ideal surgical environment for patients.

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Lithium-carbon dioxide(Li-CO_(2))batteries using high ion-conductive inorganic molten salt electrolytes have recently attracted much attention due to the high energy density and potential application of carbon neutrality.However,the poor Li-ion conductivity of the molten-salt electrolytes at room temperature(RT)makes these batteries lose most of their capacity and power as the temperature falls below 80℃.Here,inspired by the greenhouse effect,we report an RT molten salt Li-CO_(2)battery where solar energy can be efficiently harvested and converted into heat that is further localized on the cathode consisting of plasmonic ruthenium(Ru)catalysts and Li_(2)CO_(3)-based products via a greenhouse-like phenomenon.As a result,the solar-driven molten salt Li-CO_(2)battery demonstrates a larger full discharge/charge capacity of 9.5 mA h/8.1 mA h,and a longer cycle lifespan of 250 cycles at 500 mA/g with a limited capacity of 500 mA h/g at RT than the molten salt Li-CO_(2)battery at 130℃.Notably,the average temperature of the cathode increases by 8℃ after discharge to 0.75 mA h,which indicates the infrared radiation from Ru catalysts can be effectively suppressed by discharged Li_(2)CO_(3)-based products.This battery technology paves the way for developing low-temperature molten salt energy storage devices.

文摘Realizing ferromagnetic semiconductors with high Curie temperature TC is still a challenge in spintronics.Recent experiments have reported two-dimensional(2D)room temperature ferromagnetic metals,such as monolayer Cr_(3)Te_(6).In this paper,through density functional theory(DFT)calculations,we propose a method to obtain 2D high TC ferromagnetic semiconductors through element replacement in these ferromagnetic metals.We predict that monolayer(Cr_(4/6),Mo_(2/6))_(3)Te_(6),created via element replacement in monolayer Cr_(3)Te_(6),is a room-temperature ferromagnetic semiconductor exhibiting a band gap of 0.34 eV and a TC of 384 K.Our analysis reveals that the metal-to-semiconductor transition stems from the synergistic interplay of Mo-induced lattice distortion,which resolves band overlap,and the electronic contributions of Mo dopants,which further drive the formation of a distinct band gap.The origin of the high TC is traced to strong superexchange coupling between magnetic ions,analyzed via the superexchange model with DFT and Wannier function calculations.Considering the fast developments in fabrication and manipulation of 2D materials,our theoretical results propose an approach to explore high-temperature ferromagnetic semiconductors derived from experimentally obtained 2D high-temperature ferromagnetic metals through element replacement.

文摘Supersolidity is a counterintuitive quantum phase of matter where the long-range spatial order of a solid coexists with the frictionless flow characteristic of a superfluid.Recently,evidence of supersolidity has been demonstrated in polariton condensates in III-V photonic crystal microcavities by condensing into a topological bound state in the continuum,offering a new light-matter hybrid platform for exploring such quantum phase.In this work,we propose a theoretical scheme for realizing room-temperature supersolidity based on halide perovskite exciton polaritons operating in the optical parametric oscillation regime.By employing a waveguide microcavity geometry,we confine polariton scattering direction in reciprocal space,enabling controlled momentum selection.Leveraging the intrinsic nonlinear interactions among polaritons,we theoretically demonstrate the spontaneous breaking of both continuous translational symmetry and global phase symmetry,i.e.,the evidence of supersolidity.Furthermore,we identify a tunable phase transition sequence in our system:from a Bose-Einstein condensate to a supersolid phase,and ultimately to an insulating phase,as the nonlinear interaction strength increases.
文摘Optically detected magnetic resonance(ODMR)has emerged as a powerful technique for quantum sensing,enabling high-sensitivity detection of physical quantities even at room temperature.Solid-state defects,such as nitrogen-vacancy(NV)centers in diamond,have demonstrated remarkable capabilities in this domain[1–4].However,these systems are limited by their rigid lattice structures and lack tunability.
