摘要：基于第一性原理计算,我们通过将客体原子嵌入β-C_(3)N_(2)笼状结构的内在空腔中,预测了机械超硬和可控磁性的共存.以氢掺杂(H@β-C_(3)N_(2))和氟掺杂(F@β-C_(3)N_(2))为例,我们的研究表明两种掺杂构型是稳定的,并发现它们分别属于反铁磁半导体和铁磁半金属.这些有趣的磁相变源于它们在费米能级周围独特的能带结构,并可通过具有半填充占据的3D Hubbard模型和Stoner模型很好地解释.此外,H@β-C_(3)N_(2)和F@β-C_(3)N_(2)的高维氏硬度(49.0和48.2 GPa)表明它们具有笼状超硬材料特征.因此,氢和氟在β-C_(3)N_(2)笼中的掺杂分别产生了一种新型的超硬反铁磁半导体和超硬铁磁半金属,这些材料在极端条件下具有潜在的应用前景.我们的工作为设计具有优异机械性能和磁性的新型高性能多功能材料提供了一种有效的策略,这可能会为超硬材料未来在自旋电子学的应用提供理论依据.

摘要：Ⅳ族稀磁半导体因其优异的磁电性能,以及在与当前主流半导体集成技术兼容的自旋电子器件中具有广阔的应用前景而受到越来越多的关注.事实上,具有室温铁磁性的Ⅳ族稀磁半导体及其衍生器件更有望在实际中得以应用.本工作设计并制备了基于p型(Fe,Al)共掺杂SiGe薄膜和n型Ge衬底的磁性pn二极管.磁性测量以及磁阻和反常霍尔效应测试揭示了p型(Fe,Al)共掺杂SiGe薄膜的室温铁磁性.有趣的是,磁性pn异质结表现出磁场可调的整流和磁阻行为.我们的研究结果为制备具有室温铁磁性的Ⅳ族稀磁半导体提供了一种可选策略,并为Ⅳ族稀磁半导体的实际自旋电子应用提供了范例.

摘要：硼氮多重共振(MR)发光材料在宽色域有机发光二极管(OLEDs)中具有重要应用前景,因此受到广泛关注.其中,间位双硼骨架凭借其高效率和极窄的发光光谱,在蓝光发光材料的构筑中已展现出独特优势,但如何基于间位双硼骨架构筑绿光窄光谱发光分子却鲜有报道.本论文基于萘环稠合策略设计并合成了绿光发光分子BN-NAP和BNANAP,其最大发射峰分别为511和518 nm,并保持了窄光谱发光性质,其发光半峰宽(FWHM)仅为26和20 nm.利用BN-ANAP作为发光材料制备得到纯绿光OLED器件,其CIE坐标为[026,067],最大外量子效率(EQEmax)为21.0%,同时具有较小的效率滚降.

摘要：目的探索梅尼埃病患者多种症状之间的关系并通过症状网络分析将其可视化,从而帮助临床护理人员制订更加精准和个性化的干预措施。方法于2014年10月至2021年12月,选取复旦大学附属眼耳鼻喉科医院790例梅尼埃病患者进行调查。采用自行设计的症状自评量表对15个梅尼埃病相关症状进行评估,根据评估结果在R软件中构建症状网络。采用Qgraph包和Fruchterman-Reingold布局用于可视化网络。采用Bootstrapping方法评估网络的准确性和稳定性,然后采用3种中心性指标描述症状之间的关系。结果“焦虑、紧张”(98.3%)、“耳闷”(84.4%)及“耳鸣”(82.7%)是梅尼埃病患者常见症状,“耳鸣”“耳闷”及“言语识别率下降”是较严重的症状。病程越长,梅尼埃病患者各项症状的发生率及严重程度越高(P<0.05)。“单词识别能力下降”“疲劳”和“焦虑和紧张”是症状网络的核心,在整个样本中强度中心性和紧密中心性最大,对其他症状的影响最大。“言语识别率下降”“头痛”和“空间辨别和定向能力差”是整个样本中介中心性最高的症状,桥接效应最强。随着病程的发展,“跌倒发作”和“焦虑、紧张”的中心性增加,“头痛”的中心性下降。结论本研究揭示了不同病程梅尼埃病患者的症状网络。护理人员需要根据其症状严重程度和中心性的变化提供更精准的干预。当梅尼埃病患者出现多种症状时,应重点干预患者的言语识别率及其引起的不适感受。

摘要：柔性可穿戴的紫外线探测器在个体紫外线暴露监测、智能仿生眼和军事领域受到广泛关注.然而,传统不可拉伸的材料和器件结构设计限制了设备在可动态变形的人体皮肤和非平面表面上的精确监测应用和稳定附着.在本研究中,我们提出了基于氧化铜/碳-水凝胶-氧化锌/碳的新型应变隔离异质结构的本征可拉伸(拉伸应变或弯曲高达150%)紫外线探测器,该探测器具有高灵敏度(开/关比为2100%)、高稳定性(大于4000次循环),以及快速响应和恢复时间(分别为1.5和4 s).值得注意的是,该探测器通过水凝胶桥在氧化铜/碳和氧化锌/碳电极之间引入的p-n结能带结构,以及离子导电水凝胶中I^(-)/I_(3)^(-)的电化学反应机制,显著提高了其载流子效率和紫外线响应强度.本文通过集成传感器与所设计的电路板,进一步开发了一种无线紫外线报警系统,用于紫外线强度超标警报.此外,本文还设计了一种光电传感器阵列,并将其用作视网膜假体,以实现对环境紫外线强度的实时监测和成像.本文基于水凝胶基异质结构为开发可穿戴、可拉伸的光电紫外线传感器单元和成像阵列提供了一种新的可行方法.
