Among the important optoelectronic devices, ultraviolet （UV） photodetectors show wide applications in fire monitoring, biological analysis, environmental sensors, space exploration, and UV irradiation detections. Research interest has focused on the utilization of one-dimensional （1D） metal oxide nanostructures to build advanced UV photodetectors through various processes. With large surface-to-volume ratio and well-controlled morphology and composition, 1D metal oxide nanostructures are regarded as promising candidates as components for building photodetectors with excellent sensitivity, superior quantum efficiency, and fast response speed. This article reviews the latest achievements with 1D metal oxide nanostructures reported over the past five years and their applications in UV light detection. It begins with an introduction of 1D metal oxide nanostructures, and the significance, key parameters and types of photo- detectors. Then we present several kinds of widely-studied 1D nanostructures and their photodetection performance, focusing on binary oxides with wide- bandgap （such as ZnO, SnO2, Ga203, Nb2Os, and WO3） and ternary oxides （such as Zn2SnO4, Zn2GeO4, and In2Ge2OT）. Finally, the review concludes with our perspectives and outlook on future research directions in this field.

为了探究锐钛矿相TiO_(2)(a-TiO_(2))对柴油中典型氮化物(吡啶、苯胺、喹啉)及非氮化物的吸附行为和选择性,利用模拟计算方法研究了吡啶、苯胺、喹啉及非氮化物在a-TiO_(2)(101)晶面吸附过程中的吸附构型、吸附能、Mulliken电荷、电荷密度、差分电荷密度和态密度等。结果表明:吡啶、苯胺、喹啉吸附于a-TiO_(2)(101)晶面的吸附能分别为-188.59,-100.99,-201.63 kJ mol,3种氮化物均能稳定吸附于a-TiO_(2)(101)晶面,其吸附稳定性由大到小的顺序为喹啉>吡啶>苯胺;在吸附过程中,氮化物将自身一定量的电荷转移到a-TiO_(2)(101)晶面,形成氮化物→a-TiO_(2)(101)晶面的电荷转移通道;吡啶和喹啉在a-TiO_(2)(101)晶面吸附时形成N—Ti化学键,苯胺的氨基H和a-TiO_(2)(101)晶面的O形成氢键。芳烃、烷烃、环烷烃等非氮化物在a-TiO_(2)(101)晶面的吸附强度相近,均弱于氮化物。a-TiO_(2)对氮化物有较好的吸附脱除效果,能选择性去除柴油中的碱性氮化物。

This study explores a novel WNbMoTaV high-entropy thin film(HETF)in amorphous structure via pulsed laser deposition *** formation of amorphous structure of this high-entropy alloy is ascribed to the high cooling rate during the deposition *** HETF shows a smooth surface with a height fl uctuation of less than 13 *** film has a high electrical resistivity of~320.6μΩ·cm and a low corrosion current density of 0.088μA/cm *** corrosion resistance of the HETF at ambient temperature is superior to the conventional AISI 316 L stainless *** high electrical resistivity and excellent corrosion resistance of the HETF are mainly attributed to its chemical disorder,cocktail effect and homogeneous amorphous *** experimental phenomenon not only provides a basis for the preparation of amorphous alloy films with low glass forming ability by pulsed laser deposition system,also promotes the potential application of WNbMoTaV HETF in the microelectronic components as resistivity sensors.

To construct strains of the filamentous fungus Trichoderma reesei with low cellobiohydrolases while high endoglucanase activity, the Pcbh1-eg3-Tcbh1 cassette was constructed and the coding sequence of the cellobiohydrolase I (CBHI) gene was replaced with the coding sequence of the eg3 gene by homologous recombination. Disruption of the cbh1 gene was confirmed by PCR, Southern dot blot and Western hybri- dization analysis in two transformants denoted as L13 and L29. The filter paper-hydrolyzing activity of strain L29 was 60% of the parent strain Rut C30, and the CMCase activity was increased by 33%. This relatively modest increase suggested that the eg3 cDNA under the control of the cbh1 promoter was not efficiently transcribed as the wild type cbhl gene. However our results confirmed that homologous recombination could be used to construct strains of the filamentous fungus Trichoderma reesei with novel cellulase profile. Such strains are of interest from the basic science perspective and also have potential industrial applications.

Objective: To provide evidence-based recommendations for clinical application and provoke thoughts for future researchers by conducting a comprehensive summary and evaluation of the current evidence profile for the role of Chinese medicine(CM) in treating myocardial infarction(MI). Methods: Online databases including Pub Med, EMBase, Cochrane Library, Chinese National Knowledge Infrastructure(CNKI), Chinese Biomedical Medicine(CBM), VIP Journal Integration Platform, and Wanfang database were systematically searched for literatures on CM in treating MI. After screening, studies were categorized into 5 types, i.e. systematic review(SR), randomized controlled trial(RCT), observational study, case report and basic research. General information was abstracted, and the quality levels of these studies and their conclusions were summarized and assessed. Results: A total of 452 studies including 10 SRs, 123 RCTs, 47 observational studies, 28 case reports, and 244 basic researches were selected. Clinical studies centered primarily on herbal decoction and mostly were not rigorously performed. High-quality studies were predominantly on Chinese patent medicines(CPMs) such as Danshen Injection(丹参注射液), Shenmai Injection(参麦注射液), Shengmai Injection(生脉注射液) and Qishen Yiqi Dripping Pills(芪参益气滴丸). The most frequently observed pattern of drug combination was decoction plus injection. Results of SRs and clinical studies showed that CM may reduce mortality, decrease risk of complication, reduce myocardial injury, improve cardiac function and inhibit ventricular remodeling. Findings from basic researches also supported the positive role of CM in reducing infarct size and myocardial injury, promoting angiogenesis, preventing ventricular remodeling and improving cardiac function. According to the current evidence body, CM has proven effects in the prevention and treatment of MI. It is also found that the effects of CPMs vary with indications. For instance, Shenmai Injection has been found to

A hybrid triple system of order v and index A, denoted by HTS（v, λ）, is a pair （X,B） where X is a v-set and B is a collection of cyclic triples and transitive triples on X, such that every ordered pair of X belongs to A triples of B. An overlarge set of disjoint HTS（v, λ）, denoted by OLHTS（v, λ）, is a collection {（Y／{y}, .Ai）}i, such that Y is a （v ＋ 1）-set, each （Y／{y}, Ai） is an HTS（v, λ,） and all Ais form a partition of all cyclic triples and transitive triples on Y. In this paper, we shall discuss the existence problem of OLHTS（v, A） and give the following conclusion： there exists an OLHTS（v, λ） if and only if λ= 1, 2, 4, v = 0, 1 （rood 3） and v ≥ 4.

A surface acoustic wave(SAW)gyroscope measures the rate of rotational angular velocity by exploiting a phenomenon known as the SAW gyroscope *** a gyroscope is a great candidate for application in harsh environments because of the simplification of the suspension vibration mechanism necessary for traditional microelectromechanical system(MEMS)***,for the first time,we propose a novel toroidal standing-wave-mode SAW gyroscope using focused interdigitated transducers(FIDTs).Unlike traditional SAW gyroscopes that use linear IDTs to generate surface acoustic waves,which cause beam deflection and result in energy dissipation,this study uses FIDTs to concentrate the SAW energy based on structural features,resulting in better focusing performance and increased SAW *** experimental results reveal that the sensitivity of the structure is 1.51µV/(°/s),and the bias instability is 0.77°/s,which are improved by an order of magnitude compared to those of a traditional SAW ***,the FIDT component can enhance the performance of the SAW gyroscope,demonstrating its superiority for angular velocity *** work provides new insights into improving the sensitivity and performance of SAW gyroscopes.
