Abstract (in Japanese) (See Japanese page) 
(in English) A "microscopic nanomechanical measurement method" was developed by combining a transmission electron microscope (TEM) sample holder with a length extension resonator (LER) of quartz crystal and an ultra-high vacuum transmission electron microscope capable of maintaining a clean surface to observe the arrangement of the individual atoms that make up the material and measure their bond strength. Using this method, we discovered that a chain-like material consisting of platinum atoms arranged in a single row has strong atomic bond strength and unique mechanical properties so that the atomic bond does not break even when stretched considerably larger than in the case of bulk platinum crystal. First-principles calculations, supporting the experimental results, revealed that such a chain-like material is not a stable structure with minimum energy, but a structure in which the tension required for its formation is minimal. We believe that the elucidation of the unique properties of such one-dimensional materials is a major achievement that will provide guidelines for the creation of functional materials controlled at the atomic scale, which is expected to become more and more important in the future.
