| 1 | Evaluation of factors affecting the edge formability of two hot rolled multiphase steels显示文摘In this study, the effect of various factors on the hole expansion ratio and hence on the edge formability of two hot rolled multiphase steels, one with a ferrite–martensite microstructure and the other with a ferrite-bainite microstructure, was investigated through systematic microstructural and mechanical characterization. The study revealed that the microstructure of the steels, which determines their strain hardening capacity and fracture resistance, is the principal factor controlling edge formability. The influence of other factors such as tensile strength, ductility, anisotropy, and thickness, though present, are secondary. A critical evaluation of the available empirical models for hole expansion ratio prediction is also presented. | Monideepa Mukherjee Sumit Tiwari Basudev Bhattacharya | 2018 | International Journal of Minerals,Metallurgy and Materials2018，25，2： | 2 |
| 2 | Impact of Hierarchical Architecture of Cryptotermes brevis Wing on the Modulation of Bacterial Adhesion显示文摘The wing architecture is an inspiration to fabricate novel materials with exquisite properties.The current study characterizes the structure and biological function of a termite’s wing.The topography of the surface of the wing was studied by electron microscopy,and surface profilometer.The physicochemical property of the surface was analyzed by Fourier transform infrared spectroscopy,X-ray diffraction spectroscopy,energy-dispersive X-ray spectroscopy,and gas chromatography-mass spectrometry analysis of the epicuticle content.Water Contact Angle measurement confirmed the hydrophobicity of the wing surface.When microorganisms come in contact with the surface of the wing,they adhere to the wing surface due to cell surface properties of their own and the surface chemistry of the wing.The current study reported the adhesion behavior of two bacterial species.The bactericidal activity of the wing was confirmed by counting the bacterial cell viability and examination under a confocal laser scanning microscope.Adhesion of bacteria was observed under the electron microscope.Bacterial oxidative stress,the topography of the wing,and the surface chemistry of the wing are the crucial factors that induce bactericidal activity.The nanostructure along with the chemical composition of the wing can be mimicked for the fabrication of novel material with antibacterial properties. | Sanjeev Kumar Paikra Sumit Mukherjee Nibedita Nayak Janmejaya Bag Monalisa Mishra | 2022 | Journal of Bionic Engineering2022，19，2： | 0 |
