It is known that samples become contaminated in CO gas of high pressure unless care is taken with the gas supply line to an environmental transmission electron microscope. This technical note reveals the heterogeneous formation process of contaminati

Synergistic effects of steady state plasma irradiation and transient heat/particle loads to plasma facing materials are an important plasma surface interaction issue in future fusion devices. To investigate the effects systematically, a new plasma gu

The growth process of carbon nanotubes (CNTs) under CNT–CNT and CNT–substrate interactions has been observed directly by environmental transmission electron microscopy. Even a free standing CNT occasionally swings during the growth until it touch
