Multi-resonance thermally activated delayed fluorescence(MR-TADF)emitters can enable narrowband emission with high color purity and electroluminescence ***/carbonyl(N/c=O)system is receiving increasing attention while the nitrogen/boron(N/B)system has been widely *** decoration is an effective approach for N/B type MR-TADF system but always leads to broadening and red-shifting of the emission band in N/c=O MR-TADF *** attribute these unfavorable phenomena to the formation of intramolecular charge transfer between the MR-core and peripheral *** address this issue,we have developed a new strategy by decorating DMQAO(a fused N/c=O MR-core)with a triazine acceptor and a neutral terphenyl group to construct MTDMQAO and MBDMQAO,*** introduction of the triazine acceptor not only realizes efficient narrowband emission in MTDMQAO,but also accelerates the reverse intersystem crossing process through enhanced spin-orbital *** a result,MTDMQAO exhibits a significantly higher external quantum efficiency of 29.4%compared to the referent emitters,validating the rationality of our derivation *** study highlights the potential of the N/c=O system for MR-TADF emitters and provides important insights for understanding the difference between N/B and N/c=O systems.

对未经授权而处理已公开个人信息的行为,刑法理论与实务中存在入罪论、出罪论和折衷论三种观点。入罪论所根据的“二次授权必要说”存在规范衔接错位之虞;出罪论所依据的“二次授权不要说”弱化了知情同意机制的功能;折衷论中,“合理处理”“公开目的”判断标准模糊,“场景理论”逻辑不周延,“一般可访问”标准考察维度较为单一且存在客观归罪之嫌。通过明确“已公开个人信息”的范围,并从公开的主体、范围和形式三重维度分层建构,不失为一条合理路径。据此,处理非法公开的个人信息具有法益侵害性;处理完全公开的个人信息一般无须征得信息主体同意;信息主体自愿在特定范围内公开个人信息的,信息业者只有在超越该范围进行处理时才有必要取得同意。处理依规定在特定范围内公开的个人信息,信息主体有权处分时应征得同意,信息主体无权处分时不得擅自处理;信息主体处分权限不完整时,应取得双重授权。

Fluorine owing to its inherently high electronegativity exhibits charge delocalization and ion dissociation capabilities; as a result, there has been an influx of research studies focused on the utilization of fluorides to optimize solid electrolyte interfaces and provide dynamic protection of electrodes to regulate the reaction and function performance of batteries. Nonetheless, the shuttle effect and the sluggish redox reaction kinetics emphasize the potential bottlenecks of lithium-sulfur batteries. Whether fluorine modulation regulate the reaction process of Li-S chemistry? Here, the TiOF/Ti3c2MXene nanoribbons with a tailored F distribution were constructed via an NH4F fluorinated method. Relying on in situ characterizations and electrochemical analysis, the F activates the catalysis function of Ti metal atoms in the consecutive redox reaction. The positive charge of Ti metal sites is increased due to the formation of O-Ti-F bonds based on the Lewis acid-base mechanism, which contributes to the adsorption of polysulfides, provides more nucleation sites and promotes the cleavage of S-S bonds. This facilitates the deposition of Li2S at lower overpotentials. Additionally, fluorine has the capacity to capture electrons originating from Li2S dissolution due to charge compensation mechanisms. The fluorine modulation strategy holds the promise of guiding the construction of fluorine-based catalysts and facilitating the seamless integration of multiple consecutive heterogeneous catalytic processes.

霍尔传感器作为磁传感领域最常用的传感器类型,在工业生产、汽车电子、航空航天以及生物医学等方面均有广泛应用.本文利用宽禁带氮化镓(GaN)半导体耐高温、高迁移率等优点,采用标准半导体芯片制造工艺研制出AlGaN/GaN异质结结构霍尔传感器.高温应用环境下的传感器要求封装材料耐高温、产生应力低以及对传感器关键指标影响小.本文通过软件仿真树脂橡胶类3种不同封装材料封装后对传感器及键合线的性能影响规律,并通过实验验证不同材料封装前后传感器灵敏度、失调电压、温漂系数等物理参量的变化,遴选出综合性能最优的、可在550 K高温环境下使用的封装材料.最终得到封装后的霍尔传感器失调电压在1.0 mA激励电流时小于115μV,信号线性度在0~3.0 mA激励电流和0~1.0 T磁场测量范围内优于0.3%,而温漂系数在300~550 K温度范围内仅有-120.9 ppm/K,优于目前文献报道结果,因此有望应用于极端环境磁场检测中.
