Remote Absolute Roll-Angle Measurement in Range of 180° Based on Polarization ModulationSpringer Science and Business Media LLC - Tập 3 - Trang 228-235 - 2020
Xiuguo Chen, Jinbao Liao, Honggang Gu, Chuanwei Zhang, Hao Jiang, Shiyuan Liu
Remote measurement of object orientation is often required in many applications. Out of the six degrees of freedom (DoF) that determine object orientation in space, the roll angle is the most difficult to measure using optical methods. In this letter, we propose a remote Stokes roll-angle sensor that measures roll angles from the detected Stokes vectors of modulated polarized light retroreflected ...... hiện toàn bộ
Comparison of EUV Photomask Metrology Between CD-AFM and TEMSpringer Science and Business Media LLC - Tập 5 - Trang 91-100 - 2022
Gaoliang Dai, Kai Hahm, Lipfert Sebastian, Markus Heidelmann
Accurate metrology of extreme ultraviolet (EUV) photomask is a crucial task. In this paper, two different methods for reference EUV photomask metrology are compared. One is the critical dimension atomic force microscopy (CD-AFM). In the measurements, the contribution of its AFM tip geometry is usually the dominant error source, as measured AFM images are the dilated results of measured structures ...... hiện toàn bộ
Plowing-Extrusion Processes and Performance of Functional Surface Structures of Copper Current Collectors for Lithium-Ion BatteriesSpringer Science and Business Media LLC - Tập 5 - Trang 336-353 - 2022

Most copper current collectors for commercial lithium-ion batteries (LIBs) are smooth copper foils, which cannot form a stable and effective combination with electrode slurry. They are likely to deform or fall off after long-term operation, resulting in a sharp decline in battery performance. What is worse is that this condition inevitably causes internal short circuits and thus brings about secur...... hiện toàn bộ
Capillary Performance of Nanoporous Aluminum Braided Wicks Prepared by Anodic OxidationSpringer Science and Business Media LLC - Tập 5 - Trang 370-380 - 2022
Fei Gao, Longsheng Lu, Xiaokang Mei, Yu-Xiang Yu, Shitong Chai, Yang Shen, Yingxi Xie
With the rapid development of two-phase heat exchangers, the further improvement of the capillary performance of their internal wick faces a great challenge. As an important technology in the surface treatment of aluminum alloys, anodic oxidation has been widely used to develop various functional nanostructures. In this study, nanopores with diameters of 30–40 nm were fabricated on the surface of ...... hiện toàn bộ
Atomic-Scale Friction Studies on Single-Crystal Gallium Arsenide Using Atomic Force Microscope and Molecular Dynamics SimulationSpringer Science and Business Media LLC - Tập 5 - Trang 39-49 - 2021
Pengfei Fan, Saurav Goel, Xichun Luo, Hari M. Upadhyaya
This paper provides a fresh perspective and new insights into nanoscale friction by investigating it through molecular dynamics (MD) simulation and atomic force microscope (AFM) nanoscratch experiments. This work considered gallium arsenide, an important III–V direct bandgap semiconductor material residing in the zincblende structure, as a reference sample material due to its growing usage in 5G c...... hiện toàn bộ
Study on Mechanisms of Photon-Induced Material Removal on Silicon at Atomic and Close-to-Atomic ScaleSpringer Science and Business Media LLC - Tập 4 Số 4 - Trang 216-225 - 2021
Peizhi Wang, Jinshi Wang, Fengzhou Fang
AbstractThis paper presents a new approach for material removal on silicon at atomic and close-to-atomic scale assisted by photons. The corresponding mechanisms are also investigated. The proposed approach consists of two sequential steps: surface modification and photon irradiation. The back bonds of silicon atoms are first weakened by the chemisorption of chlorin...... hiện toàn bộ
Reinforcement of TiB2 Nanoparticles in Aluminium Piston Alloys for High Performance at Elevated TemperatureSpringer Science and Business Media LLC - Tập 1 - Trang 248-251 - 2018
Yijie Zhang, Sajjad Amirkhanlou, Shouxun Ji
Nano-TiB2 particles produced by in situ approaches were employed to reinforce the Mahle 174 piston alloy. Experimental results showed that, with TiB2 nanoparticles, the mechanical properties were significantly improved at ambient and elevated temperatures. The ultimate tensile property at room temperature was increased from 250 to 332 MPa. The ultimate tensile property at 300 °C was increased from...... hiện toàn bộ
Finite Element Investigation of the Influence of SiC Particle Distribution on Diamond Cutting of SiCp/Al CompositesSpringer Science and Business Media LLC - Tập 3 - Trang 251-259 - 2020
Shijin Lu, Zengqiang Li, Junjie Zhang, Jianguo Zhang, Xiaohui Wang, Yongda Yan, Tao Sun
Characteristics of internal microstructures have a strong impact on the properties of particulate reinforced metal composites. In the present work, we perform finite element simulations to elucidate fundamental mechanisms involved in the ultra-precision orthogonal cutting of aluminum-based silicon carbide composites (SiCp/Al), with an emphasis on the influence of particle distribution characterist...... hiện toàn bộ
