活性层形貌优化是实现高效、稳定的体异质结有机太阳能电池(OsC)的关键,添加剂工程被广泛用于优化OsC活性层的膜形貌.基于此,本文工作提出了一种利用具有简单结构的液晶分子4-氰基-4'-庚基联苯(7-CB)作为添加剂优化给体聚合物(PM6)在共混膜中聚集行为的策略.通过掠入射广角X射线散射、原位吸收光谱及分子动力学模拟等表征发现,7-CB通过与PM6的烷基侧链之间的范德华力和CH/π相互作用诱导PM6规整排列,增强了PM6之间的相互作用,提高了活性层薄膜的结晶度.得益于此,无任何后处理的活性层薄膜中电荷传输得到改善,电荷重组被大幅抑制.基于7-CB处理的PM6:L8-BO制备的硬质和柔性二元OsCs效率分别从15.41%和14.90%提高到18.01%和17.26%.

Thiswork investigates an oblique stagnation point flowof hybrid nanofluid over a rigid surface with power lawfluidas lubricated layers. Copper (Cu) and silver (Ag) solid particles are used as hybrid particles acting in water H2O asa base fluid. The mathematical formulation of flow configuration is presented in terms of differential systemthat isnonlinear in nature. The thermal aspects of the flow field are also investigated by assuming the surface is a heatedsurface with a constant temperature T. Numerical solutions to the governing mathematical model are calculatedby the RK45 algorithm. The results based on the numerical solution against various flow and thermal controllingparameters are presented in terms of line graphs. The specific results depict that the heat flux increases over thelubricated-indexed parameter.

在单位犯罪归责理论中,个人模式最大程度地契合了传统刑事责任理论,但其理论缺陷也较为明显,即无法适用于大型去中心化的现代企业,可能造成企业责任的严格化。组织模式充分契合了现代化的组织特征,对于激励企业合规也具有重要意义,然而,倡导组织模式不意味着对传统责任理论的摒弃,强调组织体绝对独立性的观点并不值得提倡。更合适的理论方案是,将个人模式与组织模式进行有益调和。如此,一则维持了传统刑事责任理论,不至于突破传统刑法;二则充分结合了现代组织特征,具有更强的合理性;三则有利于激励企业合规,以实现国家规制与企业自治的二元共治。

Despite the rapid development of probes for targeting single organelle, the construction of robust dual-organelle targeting probes with multicolor emission was rarely reported. Herein, two dual-emissive aggregation-induced emission luminogens(AIEgens)with donor-π-acceptor structures were designed and synthesized, namely QT-1 and QF-2. Both two AIEgens exhibited excitation wavelength-dependence defying the Kasha's rule, and could stain lipid droplets(LDs) and mitochondria in blue and red fluorescence, respectively. Moreover, thanks to the near-infrared emission and abundant reactive oxygen species(ROs) generation efficiency of QT-1, it was chosen as a photodynamic therapy agent to selectively kill cancer cells from normal cells. Upon light irradiation, an obvious decrease of mitochondrial membrane potential(MMP) and serious change of mitochondrial shape in cells were observed, which corresponded to the efficient inhibition of tumor growth in vivo. This work afforded a promising strategy for the construction of multicolor emission by tuning anti-Kasha behaviors and expanding their application in dualorganelle targeting-based phototheranostics.
