This work presents the saturable absorption(SA) properties of CsPbBr_3 perovskite quantum dots(QDs). The perovskite QDs show excellent SA performance with a nonlinear absorption coefficient of-35 × 10^(-2) cm∕GW and a figure of merit of 3.7 × 10^(-14) esu cm. Further, their use as saturable absorbers in a passively Q-switched visible solid-state laser for the generation of soliton pulses is demonstrated. These results demonstrate thepotential for the perovskite QDs to act as saturable absorbers.

提出一种基于机器学习的合金快速设计系统(ARDS),以定制所需性能的合金制备策略或预测制备策略所对应的合金性能。为此,分别对3种回归算法:线性回归(LR)、支持向量回归(SVR)和人工神经网络(BPNN)进行建模和比较以训练多性能预测模型。其中,应用SVR构建的机器学习模型被证明是最佳的。然后,基于生成对抗网络(GAN)模型原理,构建Al-Zn-Mg-Cu系铝合金快速设计系统(ARDS)。对ARDS的预测可靠性进行验证。结果表明,为了能够获得准确的制备策略,系统中极限抗拉强度(UTS)、屈服强度(YS)和伸长率(EL)的输入上限分别约为790 MPa、730 MPa和28%。此外,基于ARDS预测结果,制备了一种性能优异的新型铝合金材料,其UTS为764 MPa、YS为732 MPa、EL为10.1%,进一步验证了ARDS的可靠性。

Mechanically robust and dynamic supramolecular polymer networks enabled by [an]daisy chain backbones

Supramolecular polymer networks（SPNs） have garnered significant research interest due to their dynamic properties. However,while current developments primarily focus on managing supramolecular crosslinks, the role of polymer backbones—equally crucial to SPN properties—has not yet been sufficiently explored. Herein, we utilize mechanically interlocked [an]daisy chain as backbone to prepare a class of SPNs, where the force-induced motion of successive mechanical bonds toughens and reinforces the networks. In specific, the [an]daisy chain backbones connect with polynorbornene chains through quadruple H-bonding in the SPN networks. Compared to the control with non-slidable backbone, The representative SPN-2 exhibits a robust feature in tensile tests with high maximum stress（14.7 vs. 7.89 MPa） and toughness（83.8 vs. 48.6 MJ/m3）. Moreover, it also has superior performance in energy dissipation benefitting from the [an]daisy chain backbones as well as supramolecular crosslinks. Additionally, the SPN-2 displayed exceptional self-healing and reprocessing capabilities due to their dynamic quadrable H-bonding crosslinkers. These findings demonstrate the untapped potential of [an]daisy chain as a polymer skeleton to develop SPNs and open the door to design mechanically robust supramolecular materials with diverse smart functions.

The velocity interferometer system for any reflector(VISAR) coupled with a streaked optical pyrometer(SOP) system is used as a diagnostic tool in inertial confinement fusion(ICF) experiments involving equations of state and shock *** validate the process of adiabatically compressing the fuel shell through precise tuning of shocks in experimental campaigns for the double-cone ignition(DCI) scheme of ICF, a compact line-imaging VISAR with an SOP system is designed and implemented at the Shenguang-II upgrade laser facility. The temporal and spatial resolutions of the system are better than 30 ps and 7 μm, respectively. An illumination lens is used to adjust the lighting spot size matching with the target size. A polarization beam splitter and λ/4 waveplate are used to increase the transmission efficiency of our system. The VISAR and SOP work at 660 and 450 nm, respectively, to differentiate the signals from the scattered lights of the drive lasers. The VISAR can measure the shock velocity. At the same time, the SOP system can give the shock timing and relative strength. This system has been used in different DCI campaigns, where the generation and propagation processes of multi-shock are carefully diagnosed.
