Carbon nanotubes (CNTs) have been attracting attention because of their characteristic mechanical and electronic properties. It has been pointed out that a single-walled CNT can stretch in the axial direction at 30% strain without any bonds breaking. Therefore, it is of interest to investigate electronic properties of CNTs under high axial strain. In this study, we investigate the change in ele...

A total of 151 strains of Mycoplasma hyorhinis isolated from porcine lung lesions (weaned pigs, n=71, and finishers, n=80) were investigated for their in vitro susceptibility to 10 antimicrobial agents. Thirty-one strains (28 from weaned pigs and 3 from finishers) showed resistance to 16-membered macrolide antibiotics and lincomycin. The prevalence of the 16-membered macrolide-resistant M. hyor...

There are some precipitates that undergo transition from a coherent to semi-coherent state during growth. An example of such a precipitate in steel is carbide with a NaCl-type structure, such as TiC and NbC. The interface energy between carbide precipitate and iron is obtained via large-scale first-principles electronic structure calculation. The strain energy is estimated by structure optimiza...

We experimentally investigate the influence of slit-like confinement on the coil-stretch transition of single DNA molecules in a homogeneous planar elongational electric field. We observe a more gradual coil-stretch transition characterized by two distinct critical strain rates for DNA in confinement, different from the unconfined case where a single critical strain rate exists. We postulate th...

The electric field-induced antiferroelectric-to-ferroelectric phase transition is investigated through detailed measurements of electric polarization P, longitudinal strain x33, and transverse strain x11 developed under applied electric fields in a series of Pb0.99Nb0.02[(Zr0.57Sn0.43)1−yTiy]0.98O3 ceramics with compositions close to the antiferroelectric/ferroelectric phase boundary. It is fou...

Arterial stiffness has been shown to be a good indicator of arterial wall disease. However, a single parameter is insufficient to describe the complex stress-strain relationship of a multi-component, non-linear tissue such as the aorta. We therefore propose a new approach to measure the stress-strain relationship locally in vivo noninvasively, and present a clinically relevant parameter describ...

We investigate the electrostrictive response across a ferroelectric phase transition from first-principles calculations and show that $M$, field-induced tensor, controlling amplitude of electric-field induced strain, can be made arbitrarily large through strain engineering. take as case study epitaxial strain-induced para- to ferroelectricity ${\mathrm{KTaO}}_{3}$. magnitude electrostriction di...
