Pure organic room-temperature phosphorescence（RTP） has drawn broad attention due to its long persistent luminescence and large Stokes shift. Although the doping strategy has become one of the most effective methods to construct organic RTP systems,there is still some fuzziness of impurities, mechanisms and luminescence regulation. This study develops a series of doping RTP systems based on exciplex, in which BPC@PPZ(where BPC is N-（4-bromophenyl）-carbazole, PPZ is 10-phenyl-10H-phenothiazine) achieved the highest quantum yield of 36.3%, while BPC@CE（where CE is coronene） showed the longest lifetime of 628.5 ms. The relevant data verify the mechanism that RTP comes from the charge transfer（CT） state of exciplex. Further, the introduction of Nile Red into the exciplex system results in the triple-singlet F?rster resonance energy transfer, exhibiting a red delayed fluorescence. Besides, when incorporating the coumarin derivatives into doping system, distinct1CT*&3CT* states are generated through the CT process, accompanying a brand-new long persistent luminescence excited by visible light. These findings present an approach to regulate the CT state for achieving different persistent luminescence in the multicomponent system.

为深入探究高速公路改扩建转换区发生严重冲突的原因,使用高精度雷达采集单车实时状态数据,对单车区间初速度与加速度进行K-means聚类组合。基于聚类组合内的冲突率与路段事故率,采用Pearson系数法确定车辆的严重冲突阈值。融合转换区单车、交通流和道路因素建立二项Logistic模型,分析严重冲突因素的影响程度。结果表明:速度在45.50~85.68 km/h且加速度在-3.53~-1.31 m/s^(2)区间,或速度在27.65~34.96 km/h且加速度在1.77~3.04 m/s^(2)区间存在严重冲突;车型、交通量、平均速度、加速度、单位长度行驶转角对发生严重冲突概率有非常显著的影响;通过交通组织分流大型车、增大转换区圆曲线半径、设置合理的限速标志,能有效降低高速公路改扩建转换区的严重冲突风险。

Chimeric antigen receptor natural killer (CAR-NK) cell therapy is an alternative immunotherapy that provides robust tumor-eliminating effects without inducing life-threatening toxicities and graft-versus-host disease. CAR-NK cell therapy has enabled the development of “off-the-shelf” products that bypass the lengthy and expensive cell manufacturing process1.

特色小镇景区具有面积大、内部景点多且离散、游客住民混行等特点。为缓解景区旅游高峰拥堵、人流集聚和逃票问题,研究了景点离散的游住混合特色小镇景区收费围合方案,并通过串并联收费系统可靠性以及人流分布的合理性进行对比验证。根据景点区块划分原则,阐述了开放式、封闭式收费系统的优缺点。应用系统可靠性原理和景区客流排队理论,提出了游住混合特色小镇景区内的离散景点围合方案,建立了串并联收费系统的可靠度计算模型、人流分布分析和仿真模型。通过对贵州瓮安县草塘景区的实例应用,发现开放式收费、景点分块围合形成的并联收费系统更适合于景点离散的游住混合特色小镇景区,可提高收费系统可靠性、降低排队长度。热点景区的人流集聚问题可采取信息化主动诱导或强制手段疏解人流达到集聚标准。该研究方法可为类似的区块围合设计和人流分布研究提供参考。
