A highly sensitive laser induced fluorescence detector for capillary electrophoresis is described. With an argon laser at 488 nm for excitation, the emitted light was collected by an optical fiber and measured by it PMT. Various elements that affected the sensitivity of the detector were discussed in detail. The detection limit for fluorescein was 5.4 amole.

A series of thermodynamic functions are applied to generalize the Benedict-Webb-Rubin equation. The method has been successfully applied to this equation, which reduced the constants of BWR equation from eight to one. The calculation of PVT behavior of water over the entire thermodynamic surface is successful with satisfactory deviation.

Low-temperature fabrication of black-phase CsPbI3 perovskite films is first demonstrated by using diphenylphosphinic chloride additive under 30-50 degrees C, arising from the steric effect and chloride insertion ***-area high-quality all-inorganic perovskite films with fewer defects enhanced crystallographic orientation, and excellent environmental stability is *** record performances are demonstrated for flexible wearable photodetectors with a responsivity of 42.1 A W-1, a detectivity of 1.3 x 1014 Jones, high-fidelity image, photoplethysmography sensor functions, and high mechanical stability. Flexible wearable optoelectronic devices fabricated from organic-inorganic hybrid perovskites significantly accelerate the development of portable energy, biomedicine, and sensing fields, but their poor thermal stability hinders further applications. Conversely, all-inorganic perovskites possess excellent thermal stability, but black-phase all-inorganic perovskite film usually requires high-temperature annealing steps, which increases energy consumption and is not conducive to the fabrication of flexible wearable devices. In this work, an unprecedented low-temperature fabrication of stable black-phase CsPbI3 perovskite films is demonstrated by the in situ hydrolysis reaction of diphenylphosphinic chloride additive. The released diphenyl phosphate and chloride ions during the hydrolysis reaction significantly lower the phase transition temperature and effectively passivate the defects in the perovskite films, yielding high-performance photodetectors with a responsivity of 42.1 A W-1 and a detectivity of 1.3 x 1014 Jones. Furthermore, high-fidelity image and photoplethysmography sensors are demonstrated based on the fabricated flexible wearable photodetectors. This work provides a new perspective for the low-temperature fabrication of large-area all-inorganic perovskite flexible optoelectronic devices.

In this paper, the multi-agent systems(MASs) typically with heterogeneous unknown nonlinearities and nonidentical unknown control coefficients are studied. Although the model information of MASs is coarse, the leader-following consensus is still pursued, with a prescribed performance and zero consensus errors. Leveraging a powerful funnel control strategy, a fully distributed and completely relative-state-dependent protocol is designed. Distinctively, the time-varying function characterizing the performance boundary is introduced, not only to construct the funnel gains but also as an indispensable part of the protocol,enhancing the control ability and enabling the consensus errors to converge to zero(rather than a residual set). Remark that when control directions are unknown, coexisting with inherent system nonlinearities, it is essential to incorporate an additional compensation mechanism while imposing a hierarchical structure of communication topology for the control design and analysis. Simulation examples are given to illustrate the effectiveness of the theoretical results.

A new equation of state based on hard-sphere perturbed theory was developed. This equation combined the CS repulsive term and Guo-Du attractive term. Parameters of 38 substances were estimated, the pressure-volume-temperature properties were calculated and compared with two other equations. The results show that this equation is more accurate.

秦代律篇主要是以职官律和职事律间杂方式进行分篇,至秦末职官律逐渐向职事律转化。汉初完全继承了秦代的法律体系,并将与盗、贼、亡、收、复、迁等犯罪行为逐渐作为重要的约束对象,而对于抓捕、鞫审、告劾、拘押等有关官吏规范法律进行集合,形成了规范刑事犯罪为主体的“狱律”,其他具有规范性质的律章则放入了“旁律”。至此形成了“狱律”“旁律”体系的二分结构,而“旁律”则作为“狱律”条文的重要来源。

社区社会组织作为基层社会治理格局中的重要治理主体,其有活力、有秩序的发展并融入基层社会治理格局是我国社会发展过程中的重要现象。作为顺应现实需求和政策推动的产物,社区社会组织的自身发展经历了从动顺应到行政吸纳的发展过程,并形成了吸纳秩序。然而,随着社区社会组织自身的规范性发展以及治理性功能显现,其逐步超越了吸纳秩序从而实现策略性合作。目前,社区社会组织正通过融合融入、结构调适、外部驱动等策略,在基层社会治理格局中实现目标方向、多元利益、外部资源等多层次的整合性发展。
