Constructing the stable,low-cost,efficient,and highly adaptable visible light-driven photocatalyst to implement the synergistic effect of photocatalysis and adsorption has been excavated a promising strategy to deal with antibiotic pollution in water bodies.Herein,a novel 3 D ternary Z-scheme heterojunction photocatalyst Ni_(2)P/Bi_(2)MoO_(6)/g-C_(3)N_(4)(Ni_(2)P/BMO/CN)was fabricated by a simple solvothermal method in which the broad spectrum antibiotics(mainly tetracyclines and supplemented by quinolones)were used as target pollution sources to evaluate its adsorption and photocatalytic performance.Notably,the Zscheme composite significantly exhibit the enhancement for degradation efficiency of tetracycline and other antibiotic by using Ni_(2)P nanoparticles as electron conductor.Active species capture experiment and electron spin resonance(ESR)technology reveal the mechanism of Z-scheme Ni_(2)P/BMO/CN photocatalytic reaction in detail.In addition,based on the identification of intermediates by liquid chromatography–mass spectroscopy(LC–MS),the possible photocatalytic degradation pathways of TC were proposed.

Designing an effective and stable composite photocatalyst is of significance for the further realization of practical applications. In this study, a series of CoP/CoO composites are successfully prepared by a straight one-step phosphating method. The reasonable design and controllable preparation of CoP/CoO composite make it exhibit improved photocatalytic performance for overall water splitting and excellent stability under visible light irradiation in comparison with pure CoO, which is derived from the CoP nanoparticles well dispersed on the(111) facets of CoO octahedrons, intimate interface between them and efficiently accelerated of photo-induced electrons from CoO to CoP. This study presents a simple method to design highly-effective composite photocatalysts for overall water splitting to meet the energy demand.

The compound[(CH3)2 CH-C3 H17 N][CoBr4](1)based on quinuclidine derivatives was achieved by the solution synthetic method and characterized by elemental analysis,infrared spectroscopy,single-crystal X-ray structural analysis and dielectric measurement,respectively.Variable-temperature single-crystal X-ray diffraction suggested that the compound unde rwent the phase transition from the space group C2/c to Cc.The polarization curve was measured using the Sawyer-Tower circuit.The structural phase transitions of 1 was ascribed to the distortion of a[(CH3)2 CH-C3 H17N]2+cation from this inorganicorganic hybrid material[(CH3)2 CH-C3 H17N][CoBr4].The strong change in dielectric anomalies makes compound 1 a suitable candidate for promising switchable dielectric materials.This work represents a feasible strategy thought for the targeted harvesting of low temperature ferroelectrics.

A highly stable and luminescent metal-organic framework(LMOF) with layered structure,namely,C6H4N5OZn(1) has been successfully achieved and fully characterized by single crystal X-ray diffraction,powder X-ray diffractions,fluorescence titration and thermogravimetry.This blue-light emitting compound 1 exhibit outstanding stability and can detect Fe3+ and Cu2+ in water specifically,presenting potential application in the field of fluorescent probe technology.Fluorescence titration experiments indicate that the detection of Fe3+ ions by 1 is more significant than that of Cu2+ ions in terms of Ksv value.Furthermore,guest-assisted exfoliation of layered MOF 1 is efficiently carried out through ether O—H hydrogen bond or π…π interactions between the layered host structure and intercalated guest molecules(4,4’-oxybisbenzoic acid and triphenylamine).Tyndal scattering was observed in the suspensions of obtained MOF nanosheets.This study shows that the compound 1 with unique metal ion sensing properties can be applied as a probe material in water pollution treatment field,but also opens up the opportunity for synthesizing luminescent MONs through the "bottom-up" guest intercalation methodology.

背景:随着检查技术的革新,不同分期脊柱转移瘤患者逐年增多,经皮椎体成形是脊柱转移瘤重要的治疗手段,但其治疗不同分期、不同活动方式肿瘤的术后生物力学疗效尚未见报道。目的:基于三维有限元模型模拟胸椎T_(10)骨肿瘤转移不同位置的应力及位移情况。方法:根据1例30岁健康男性胸椎三维CT扫描数据,采用Mimics软件构建胸椎(T_(9)-T_(11))的三维几何模型,包括肋骨、韧带及椎间盘。模拟被胸椎转移瘤侵袭的T_(9)-T_(11)椎体及其后胸椎不同部位的三维模型,包括椎体结构完整的对照组,单侧转移累及椎体区(实验组1),单侧转移累及椎体和椎弓根区(实验组2),单侧转移累及椎体、椎弓根和横突区(实验组3),双侧转移累及椎体、椎弓根和横突区(实验组4)。利用Abaqus软件创建三维有限元模型,对负重、屈曲、伸展、旋转工况下VonMises应力分布及模型的位移情况进行分析。结果与结论:①在对不同实验组加载点在负重、屈曲、伸展、旋转工况下最大总位移的研究中,随着转移瘤侵袭部位及侵袭面的增多,加载点的总位移在增大,整体刚度降低,尤其实验组4加载点的总位移最大;②在屈曲工况下椎体、椎弓根破坏后明显增加最大Von Mises应力值,而在此基础上增加胸肋关节破坏,其最大Von Mises应力值基本不变;③有限元分析并模拟骨肿瘤模型的基础上,将骨水泥区域的单元设置为一个单独的set集合,后将骨水泥区域设置为对应的材料属性以模拟骨水泥填充,结果发现,负重、屈曲、伸展、旋转工况下最大总位移均小于各实验组;④模拟经皮椎体成形治疗后患者在负重、屈曲、伸展、旋转工况下的最大应力值相较于骨肿瘤模型大幅度降低;⑤提示基于胸椎T_(9)-T_(11)的三维有限元模型构建有利于对胸椎骨肿瘤转移生物力学特性的研究,并能够在胸椎骨肿瘤转移模型的基础上准确模拟经皮椎体成形后加载点在不同工况下的总位移及最大VonMises应力情况。

In order to solve the conflict between indoor lighting and PV cells in building-integrated photovoltaic/thermal(BIPV/T) systems, a glass curtain wall system based on a tiny transmissive concentrator is proposed. This glass curtain wall has a direct influence on the heat transfer between indoor and outdoor, and the operating parameters of air and water inlet temperature, indoor and outdoor temperature, and radiation intensity have a significant influence on the heat transfer characteristics of the glass curtain wall. The 3D model is established by SoildWorks software, and the thermal characteristics of the new glass curtain wall system are simulated through computational fluid dynamics(CFD) method. Thermal performance was tested under actual weather for the winter working conditions. The CFD simulation results are verified by the test results under actual weather. The results show that thermal efficiency simulation results are in good agreement with the experimental results of the new glass curtain wall system. The simulation conditions were designed by using the orthogonal method, and the significance analysis of the influencing factors of the indoor wall surface heat gain was carried out. With the increase of the bottom heat flux and the air velocity, the heat absorption of the inner wall surface increases. When the wind speed is 0.1 m/s, the heat flow on the bottom surface rises from 500 W/m^(2) to 2500 W/m^(2), and the heat flow intensity on the interior wall changes from 10.31 W/m^(2) to -29.12 W/m^(2). Under typical working conditions, the new glass curtain wall system can reduce the indoor heat load by 47.5% than ordinary glass curtain wall.

The technique of facial attribute manipulation has found increasing application,but it remains challenging to restrict editing of attributes so that a face’s unique details are preserved.In this paper,we introduce our method,which we call a mask-adversarial autoencoder(M-AAE).It combines a variational autoencoder(VAE)and a generative adversarial network(GAN)for photorealistic image generation.We use partial dilated layers to modify a few pixels in the feature maps of an encoder,changing the attribute strength continuously without hindering global information.Our training objectives for the VAE and GAN are reinforced by supervision of face recognition loss and cycle consistency loss,to faithfully preserve facial details.Moreover,we generate facial masks to enforce background consistency,which allows our training to focus on the foreground face rather than the background.Experimental results demonstrate that our method can generate high-quality images with varying attributes,and outperforms existing methods in detail preservation.
