Fabrication of Compositionally Graded NiTi Shape Memory Alloy Laminated Composites Through Hot Roll Bonding and its Characterization

open access: yesAdvanced Engineering Materials, EarlyView.
A novel technique for fabricating monolithic functionally graded NiTi shape memory alloy (SMA) laminated hybrid composite has been developed. An excellent metallurgical bonding can be established between two compositionally different NiTi SMAs through spark plasma sintering joining/diffusion bonding followed by hot roll bonding.

Determining the direction of a nanowire's flexural vibrations by micro-lens optical fiber interferometer [PDF]

open access: yesarXiv, 2017
Nanowires are perfect transducers for ultra-sensitive detections of force and mass. For small mass sensing, recent advances in detecting more properties than their masses with high sensitivity for absorbed particles onto a nanowire rely on identifications of two orthogonal flexural vibration modes of the nanowire.
