| 1 | Manufacture and characterization of graphene membranes with suspended silicon proof masses for MEMS and NEMS applications显示文摘Graphene’s unparalleled strength,chemical stability,ultimate surface-to-volume ratio and excellent electronic properties make it an ideal candidate as a material for membranes in micro-and nanoelectromechanical systems(MEMS and NEMS).However,the integration of graphene into MEMS or NEMS devices and suspended structures such as proof masses on graphene membranes raises several technological challenges,including collapse and rupture of the graphene.We have developed a robust route for realizing membranes made of double-layer CVD graphene and suspending large silicon proof masses on membranes with high yields.We have demonstrated the manufacture of square graphene membranes with side lengths from 7µm to 110µm,and suspended proof masses consisting of solid silicon cubes that are from 5µm×5µm×16.4µm to 100µm×100µm×16.4µm in size.Our approach is compatible with wafer-scale MEMS and semiconductor manufacturing technologies,and the manufacturing yields of the graphene membranes with suspended proof masses were>90%,with>70%of the graphene membranes having>90%graphene area without visible defects.The measured resonance frequencies of the realized structures ranged from tens to hundreds of kHz,with quality factors ranging from 63 to 148.The graphene membranes with suspended proof masses were extremely robust,and were able to withstand indentation forces from an atomic force microscope(AFM)tip of up to~7000nN.The proposed approach for the reliable and large-scale manufacture of graphene membranes with suspended proof masses will enable the development and study of innovative NEMS devices with new functionalities and improved performances. | Xuge Fan Anderson D.Smith Fredrik Forsberg Stefan Wagner Stephan Schroder Sayedeh Shirin Afyouni Akbari Andreas C.Fischer Luis Guillermo Villanueva Mikael Ostling Max C.Lemme Frank Niklaus | 2020 | Microsystems & Nanoengineering2020，6，1： | 4 |

| 5 | Nanoelectromechanical Sensors Based on Suspended 2D Materials显示文摘The unique properties and atomic thickness of two-dimensional(2D)materials enable smaller and better nanoelectromechanical sensors with novel functionalities.During the last decade,many studies have successfully shown the feasibility of using suspended membranes of 2D materials in pressure sensors,microphones,accelerometers,and mass and gas sensors.In this review,we explain the different sensing concepts and give an overview of the relevant material properties,fabrication routes,and device operation principles.Finally,we discuss sensor readout and integration methods and provide comparisons against the state of the art to show both the challenges and promises of 2D material-based nanoelectromechanical sensing. | Max C.Lemme Stefan Wagner Kangho Lee Xuge Fan Gerard J.Verbiest Sebastian Wittmann Sebastian Lukas Robin J.Dolleman Frank Niklaus Herre S.Jvan der Zant Georg S.Duesberg Peter G.Steeneken | 2020 | Research2020，，1： | 1 |

| 7 | LED照明产品光色参数测量比对及结果分析显示文摘为了更好地了解LED照明产品的测量差异,寻找存在差异的原因,提高实验室之间测量结果的一致性,中国、德国两个国家的六个实验室对两组商用LED照明产品,包括LED球泡灯、LED筒灯、LED路灯进行了测量比对。两个国家的不同实验室采用了不同的测试设备,并分别溯源至本国的计量标准,比对结果表明各实验室间光通量的差异在±5%内,色温的偏差为±250 K内,虽大于中德两国光通量和色温单位量值之间的偏差,但仍然可以满足产品生产过程中的质量控制及国际贸易的需求。这表明只要测量设备按期校准、测试样品的测试条件尽量接近,不同实验室测试结果之间的偏差可以控制在可接受的范围之内。 | 孙雪娇 赵丽霞 GANEV Hristo WAGNER Max KHANH Tran Quoc | 2019 | 照明工程学报2019，30，2： | 0 |
| 8 | Physics, chemistry, and Hirshfeld surface analyses of gamma-irradiated thalidomide to evaluate behavior under sterilization doses显示文摘Thalidomide was indicated as a sedative and antiemetic and prescribed for pregnant women. Its tragic teratogenic effects culminated in withdrawal from the market. Since the discovery of its anti-angiogenic and anti-inflammatory actions, thalidomide has been used in the treatment of leprosy and multiple myeloma,which justify studies of its stability. We investigated the effects of irradiation of thalidomide up to 100 k Gy(fourfold the usual sterilizing dose for pharmaceutics). The β polymorph of thalidomide was obtained in an isothermal experiment at 270 °C. All samples underwent gamma irradiation for specific times. At different doses, decomposition of the pharmaceutical was not observed up to 100 k Gy. The observed effect was angle turning between the phthalimide and glutarimide rings modulated by repulsion towards the carbonyl group,leading to a stable energetic configuration, as measured by the equilibrium in the torsion angle after irradiation. The thalidomide molecule has a center of symmetry, so a full turn starting from 57.3° will lead to an identical molecule. Further irradiation will start the process again. Samples irradiated at 30 and 100 k Gy have more compact unit cells and a lower volume, which leads to an increase in the intermolecular hydrogen interaction within the unit cell, resulting in higher thermal stability for polymorph α. | Valner A.F.S.N.Mussel Max R Ferreira Maria B.E Marques Maria I.Yoshida Mariana R.Almeida Bernardo L.Rodrigues Wagner N.Mussel | 2018 | Journal of Pharmaceutical Analysis2018，8，3： | 0 |
