Mouse Anti-MET Hybridoma [6E6.22.7]

In situ electron microscopy can be an effective tool to investigate the underlying science of many transformation mechanisms in materials science. Useful utilization of these experimentations will provide greater insight into many of the existing theories, as microstructural changes can be visualized in real time under some applied constraints. In this study, we have investigated two basic phase transformation phenomena: diffusionless and diffusional mechanisms with the help of in situ cooling and heating techniques in scanning electron microscope (SEM). In situ cooling experiments have been carried out on secondary hardening ultra-high-strength steels to understand the diffusionless transformation of austenite to martensite. Nucleation and growth of the martensites have been observed with cooling in different steps to -194 degrees C. Details of the formation of different variants of martensites in steel were studied with the help of orientation imaging microscopy. Diffusional transformations were studied in terms of oxidation of pure copper in SEM using in situ heating technique. Different heating cycles were adopted for different samples by in situ heating to a maximum temperature of 950 degrees C for the oxidation study. Nucleation of copper oxides and subsequent growth of the copper oxides at different temperatures were studied systematically. Raman spectroscopy and orientation imaging were done to confirm the formation of oxides and their orientations. The thermal cycling phenomenon was replicated inside SEM with heating and cooling and it has been demonstrated how the nature of copper and its oxides changes with the thermal cycle. This article is part of a discussion meeting issue 'Dynamic in situ microscopy relating structure and function'.

In this article, a module-based plug-n-play (PnP) dc microgrid (MG) is introduced to help rural electrification. It provides a bottom-up way to form an MG with multilayer expandability and PnP feature. The module-based MG overcomes the drawback of conventional MG that requires central design and implementation which leads to high upfront cost and long lead time. It provides an organic way to form an MG that allows user to scale up the system as their demands grow, and fully utilize the existing resources. The proposed MG module is expandable on different layers that can meet the requirements of customers with different power consumption requirements. Each module, which contains PV generation and energy storage, can work as a stand-alone solar home system. Multiple modules can be connected as a group to scale up the local power supply. Groups can be interconnected through a public bus with gateway converter modules to form a community network, which can supply public usage and enable power exchange in a community range with relatively high distribution efficiency. The control of the proposed MG is in a fully decentralized manner such that central control and communication network can be omitted, which makes the system more user-friendly and highly robust. Detailed design, analysis, and implementation of the proposed PnP MG is provided in this article. Simulation and experimental results have been provided to verify the concept and analytical study.
