钙钛矿太阳能电池设备中正确选择的光管理策略在实现高功率转换效率方面是必不可少的。应考虑降低反射损失，前表面的质地化，类似于已建立的太阳能电池技术中使用的反射损失。在本文中，使用滚筒纳米膜技术应用于平面钙钛矿太阳能电池，以最大程度地减少反射损失。The results show that the applied honeycomb pattern reduces the solar-weighted reflectance from 13.6% to 2.7%, which enhances the current density of the unmodified cell by 2.1 mA cm − 2 , outperforming the commonly used planar MgF 2 antireflective coating by 0.5 mA cm − 2 .实验结果与光学建模结合在一起，以发现优化的结构，并预测太阳模块中的光学行为。这项工作中使用的过程可以转移到Perovskite-Silicon串联太阳能电池，为未来设备的反射减少提供了有希望的途径。

社论：放线菌天然产品：隔离，结构阐明，生物学活性，生物合成和产量改善
Natural products from Actinobacteria,Hsi commonly known as actinomycetes, have historically provided humans with numerous antibiotics (e.g., streptomycin, gentamicin, and vancomycin) ( Schatz et al., 1944 ; Cooper and Yudis, 1967 ; Rake et al., 1986 ), anticancer agents (e.g., doxorubicin, bleomycin, and Calicheamicins（Shastri等，1971; Maiese等，1989）和Agrochemicals（例如Avermectin和pinosad）（West，1996; Molinari et al。，2010）。应强调，所有认可的抗生素中约有三分之二来自放线菌，主要由链霉菌物种衍生出来，强调了这些微生物的重要性（Barka等，2016）。从放线菌对新天然产物的发现和生物学评估是后基因组时代的无尽领域，主要是由微生物基因组学和合成生物学的进步驱动。了解放线菌天然产物的生物合成不仅阐明了自然如何从小型构件（例如氨基酸和酰基-COA）中构建这些复杂分子，而且还为提高工业发展的产量提供了基础。一些天然产品具有前所未有的结构支架和令人印象深刻的生物学活动，激发了合成和药物化学家设计和综合药物的下一代。此外，放线菌具有通过发酵技术实现天然产物的优势。

疲劳试验控制器的组成部分
Components of Fatigue Test Controller Manjula B K EEE Department BMSIT&M Abstract: This paper describes about the development of computer controlled single channel controller used in servo hydraulic test system for fatigue testing of materials. The closed loop control obtained with load cell and LVDT which provides an electrical signal to the controller proportional to the mechanical position of the actuator or load exerted by it. The electrical signal is passed through signal conditioning circuitry for amplification of the signal which is fed to the servo-controller to generate an error signal. The feedback mode whether in stroke (LVDT) or Load mode is compared with respective set points using a differential amplifier. Add -on boards of digital to analog converter is used to convert the set-points which are in digital form to analog value. The operations of the controller are displayed on the console of the computer. Keywords: Fatigue test, Controller DAC,ADC, Load mode and stroke mode 1. Introduction Fatigue testing is critical requirement of aircraft to determine the life span of the aircraft. A fatigue test helps determine a material's ability to withstand cyclic fatigue loading conditions. By design, a material is selected to meet or exceed service loads that are anticipated in fatigue testing applications. Cyclic fatigue tests produce repeated loading and unloading in tension, compression, bending, torsion or combinations of these stresses. Fatigue tests are commonly loaded in tension – tension, compression – compression and tension into compression and reverse. To perform a fatigue test a sample is loaded into a fatigue tester or fatigue test machine and loaded using the pre- determined test stress, then unloaded to either zero load or an opposite load[1]. This cycle of loading and unloading is then repeated until the end of the test is reached. The test may be run to a pre-determined number of cycles or until the sample has failed depending on the parameters of the test[2]. The purpose of a fatigue test usually is to determine the lifespan that may be expected from a material subjected to cyclic loading, however fatigue strength and crack resistance are commonly sought values as well. The fatigue life of a material is the total number of cycles that a material can be subjected to under a single loading scheme. A fatigue test is also used for the determination of the maximum load that a sample can withstand for a specified number of cycles. All of these characteristics are extremely important in any industry where a material is subject to fluctuating instead of constant forces. Types of fatigue tests: There are several common types of fatigue testing as well as two common forms: load controlled high cycle and strain controlled low cycle fatigue. A high cycle test tends to be associated with loads in the elastic regime and low cycle fatigue tests generally involve plastic deformations. Types of materials for fatigue tests Most of the materials may experience fatigue in one way or another during the lifespan of their application. However, in applications where fatigue is a factor it is common to find components made from metals or composites. These materials have a higher fatigue limit than others because of
