Research Progress on Career Development of Nursing Staff

There are few studies on career development as an exclusive concept in the field of nursing in China.Currently,research related to the career development of nursing staff primarily relies on inductive evaluation tools,and there is less systematic summarization of this research.This paper reviews the concept,evaluation tools,and influencing factors of nursing career development,aiming to provide a reference for future research in this area.

Meta-Analysis of the Effect of the Escape Room Teaching Method on Nursing Education

Objectives:A meta-analysis was conducted to systematically evaluate the effect of the escape room teaching method on nursing education.Methods:We searched PubMed,Medline,Web of Science,CNKI,VIP,and Wanfang databases,with a search time frame from the first day of database establishment to October 2022.Two researchers evaluated the quality of the obtained literature and extracted the data.The RevMan5.4 software was used for meta-analysis.Results:A total of 7 studies involving 1487 nursing students were included.Compared with the control group,the escape room teaching method improved the professional performance of nursing students[standardized mean difference(SMD)=0.98,95%confidence interval(CI;0.38,1.59),P<0.0001].The critical thinking ability of nursing students was enhanced[mean difference(MD)=12.64,95%CI(7.91,17.37),P<0.0001],and the investment level of nursing students in learning was improved[MD=4.18,95%CI(1.74,6.62),P<0.0001].Conclusion:The escape room teaching method can improve nursing students’professional performance,critical thinking ability,and learning engagement level.There is no significant difference in the impact of nursing teaching satisfaction,and there is still a lack of data support.This paper is limited by the quality and quantity of included literature,and more high-quality studies are still needed to further demonstrate the above conclusions.

Optical Properties, Electronic Energy Level Structure and Electroluminescent Characteristics of Salicylaldehyde Anil Zinc

A new electroluminescent material, salicylaldehyde anil zinc （SAZ） was synthesized, which can form high quality, thermal stability, nano-scale amorphous films by vacuum evaporation. Its structure, thermal stability were characterized by infrared （IR） spectra, differential thermal analysis-thermogravimetry （DTA-TG） analysis, respectively. The optical properties of SAZ were investigated by UV absorption spectra, Photoluminescence （PL） excitation and emission spectra. The highest occupied molecular orbits （HOMO）, lowest unoccupied molecular orbits （LUMO） and optical band gap were evaluated by cyclic voltammetry curve and optical absorption band edge. The electroluminescent devices using SAZ as the emissive layer emit green light with a peak wavelength at 509 nm and a brightness of about 3.1 cd/m^2.

原子级化学反应促进可弱光探测有机光电倍增探测器的外量子效率超过10^(8)%

外量子效率远大于100%、低成本、溶液法制备的倍增型有机光电探测器(PM-OPDs)引起广泛关注.但该类器件因阳极欧姆接触带来暗电流的恶化,使其弱光探测并不理想.基于此,本文提出了原子级化学反应改善PM-OPDs暗电流及弱光探测策略,进而带来器件综合性能的显著提升.具体地,本文利用原子层沉积技术在空穴传输层PEDOT:PSS与活性层P3HT:PC71BM(100:1)之间引入0.8 nm厚的Al_(2)O_(3)界面层,通过对薄膜拉曼、XPS及FT-IR性能进行表征,发现原子级厚度的Al_(2)O_(3)可与PEDOT:PSS的化学基团发生反应,调节PEDOT:PSS的功函数,进而在阳极一侧形成肖特基接触.通过与阴极肖特基接触协同,器件在保持高倍增行为的同时,暗电流显著降低.最终,器件的弱光探测性能有所改善,相比于标准器件(可探测64 nW/cm^(2)弱光),Al_(2)O_(3)修饰器件可探测低至2.5 nW/cm^(2)的弱光,且相应的外量子效率和响应率分别达到4.31×10^(8)%,1.85×10^(6)A/W,达到目前报道PM-OPDs的最优值.此策略在新型柔性电子产品及医学成像领域具有很好的应用前景.

High detectivity photodetectors based on perovskite nanowires with suppressed surface defects

Solution-processable,single-crystalline perovskite nanowires are ideal candidates for developing low-cost photodetectors,but their detectivities are limited due to a high level of unintentional defects.Through the surfaceinitiated solution-growth method,we fabricated high-quality,single-crystalline,defects-suppressed MAPbI_(3) nanowires,which possess atomically smooth side surfaces with a surface roughness of 0.27 nm,corresponding to a carrier lifetime of 112.9 ns.By forming ohmic MAPbI_(3)∕Au contacts through the dry contact method,highperformance metal–semiconductor–metal photodetectors have been demonstrated with a record large linear dynamic range of 157 dB along with a record high detectivity of 1.2×10^(14) Jones at an illumination power density of 5.5 nW∕cm^(2).Such superior photodetector performance metrics are attributed to,first,the defects-suppressed property of the as-grown MAPbI_(3) nanowires,which leads to a quite low noise current in the dark,and second,the ohmic contact between MAPbI_(3) and Au interfaces,which gives rise to an improved responsivity compared with the Schottky contact counterpart.The realized high-performance MAPbI_(3) nanowire photodetector advances the development of low-cost photodetectors and has potential applications in weak-signal photodetection.

Passivation of degradation path enables high performance perovskite nanoplatelet lasers with high operational stability

MAPbI_(3)perovskite has attracted widespread interests for developing low-cost near infrared semiconductor gain media.However,it faces the instability issue under operation conditions,which remains a critical challenge.It is found that the instability of the MAPbI_(3)nanoplatelet laser comes from the thermal-induced degradation progressing from the surface defects towards neighboring regions.By using PbI_(2) passivation,the defect-initiated degradation is significantly suppressed and the nanoplatelet degrades in a layer-by-layer way,enabling the MAPbI_(3)laser to sustain for 4500 s(2.7×10^(7) pulses),which is nearly three times longer than that of the nanoplatelet laser without passivation.Meanwhile,the PbI_(2) passivated MAPbI_(3)nanoplatelet laser with the nanoplatelet cavity displays a maximum quality factor up to∼7800,the highest reported for all MAPbI_(3)nanoplatelet cavities.Furthermore,a high stability MAPbI_(3)nanoplatelet laser that can last for 8500 s(5.1×10^(7) pulses)is demonstrated based on a dual passivation strategy,by retarding the defect-initiated degradation and surface-initiated degradation simultaneously.This work provides in-depth insights for understanding the operating degradation of perovskite lasers,and the dual passivation strategy paves the way for developing high stability near infrared semiconductor laser media.
