Monodisperse graphene oxide （GO） microspheres were synthesized via microfluidics technology as a novel adsorbent for rapid （in 2 rain） and high efficiency （98%） removal of perfluorooctane sulfonate （PFOS） from water. This novel material is a potential solution for treatment of bioaccumulative organic polluted water. To achieve improved performance, Mg2＋ was introduced into GO, and the metal composite exhibited significantly improved PFOS removal effidency owing to bridging and interaction between Mg~＋ and the PFOS molecules, which was supported by density functional theory and X-ray photoelectron spectroscopy （XPS）. This facile strategy may be extended to the synthesis of other spheres with unique structural features for application in water treatment.

Dear Editor,This letter is concerned with stability analysis and stabilization design for sampled-data based load frequency control(LFC) systems via a data-driven method. By describing the dynamic behavior of LFC systems based on a data-based representation, a stability criterion is derived to obtain the admissible maximum sampling interval(MSI) for a given controller and a design condition of the PI-type controller is further developed to meet the required MSI. Finally, the effectiveness of the proposed methods is verified by a case study.

A novel SrSn(OH)_(6) photocatalyst with large plate and particle size were synthesized via a facile chemical precipitation method. The photocatalytic activity of the SrSn(OH)_(6) was evaluated by the removal of NO at ppb level under UV light irradiation. Based on the ESR measurements, SrSn(OH)_(6) photocatalyst was found to have the ability to generate the main active species of O_(2)^(·-), ^(·)OH and ^(1)O_(2) during the photocatalytic process. Moreover, SrSn(OH)_(6) photocatalyst not only exhibits high photocatalytic activity for NO removal (79.6%), but also has good stability after five cycles. The in situ diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS) was used to investigate the NO_(x) transfer pathway and the intermediate products distribution during the adsorption and photocatalytic NO oxidation process. The present work not only provides an efficient material for air pollutants purification at room temperature but also in-depth understanding of the mechanism involved in the photocatalytic NO removal process.

粒子激发X射线谱仪(APXS)是中国探月工程二期嫦娥三号月球巡视器的有效载荷之一。简要介绍APXS的工作原理、组成部分,以及它在月面的工作环境,通过模拟及实验研究了月面热环境对APXS的影响,结果显示,APXS将工作在显著的变温过程中。相对恒温过程,APXS在变温过程中的能量分辨率明显变差。为了消除该温度效应的影响,提出了一种基于皮尔逊卡方检验(Pearson’s chi-squared test)的修正方法,能够有效提高变温过程中的能量分辨率。通过温度循环试验中变温阶段的数据对该方法进行了测试,结果表明,该方法具有很好的修正效果和较高的可靠性。

Endoplasmic reticulum(ER) viscosity has emerged as a new potential biomarker for hepatic fibrosis(HF). Herein, we report the first ER-targeting viscosity-responsive near-infrared(NIR) fluorescent probe HBT-PP for investigations of HF *** twisted intramolecular charge transfer(TICT) and the excited state intramolecular proton transfer(ESIPT) are combined to endow HBT-PP with the selective response towards viscosity(～62-fold) and a super large stokes shift(～320 nm). HBT-PP mainly targets organelle ER and is able to image the drug-or alcohol-induced viscosity elevation in living cells. Significantly,HBT-PP was successfully applied to visualize the gender difference in HF and the protective role of estrogen in restraining HF progression. Of note, after 10 min of stain with HBT-PP, HF lesions showed a stage-based response, indicating the potential of this probe in fast and early diagnosis of HF. These results clearly demonstrated the promising application of HBT-PP as a new tool for exploring ER viscosity-involved physiological and pathological processes.
