CROSS-SECTION STRUCTURE OF PURE-COPPER ALLOY WIRE FOR ULTRASONIC BONDING PROBLEM TO BE SOLVED: To provide a cross-section structure of a wire which is wide in the width of a process window of an ultrasonic bonding even with a pure copper alloy connection wiring line....
of many first and second row transition metals in acidic conditions during the ORR, further alloy-based routes towards precious-metal elimination at low pH are limited7,8,9. In contrast, anion exchange membrane FCs (AEMFCs) offer a higher pH regime, enabling the stable use of less-expensive...
As seen for 3 nm-sized nanoparticles (NPs) anchored on well-defined rutile tita- nia nanorods, Au and Pd atoms form a solid-solution alloy, whilst Au and Rh atoms segregate into single-phase domains within the NPs15. Nevertheless, in both cases the interaction of the active metal (Pd,...
(CNN) model for learning and predicting the energy of a system by training geometries of cluster units containing both metal and non-metal atoms, viz. C5, N42−, N64−, Aun(n = 2 − 8) and AunAgm(2 ≤ n + m ≤ 8) clusters as prototype examples. ...

In particular the superelasticity derives from the fact that the crystal structure changes reversibly due to the martensitic transformation when loading and unloading stress, and creates flexibility as a rubber-like metal. The crystal structure of noble alloys for dental use depends on the alloy ...
