High-Velocity Shear and Soft Friction at the Nanometer Scale

open access: yesFrontiers in Mechanical Engineering, 2021
We study high-speed friction on soft polymer materials by measuring the amplitude dependence of cyclic lateral forces on the atomic force microscope (AFM) tip as it slides on the surface with fixed contact force.

Pseudo-capacitive and kinetic enhancement of metal oxides and pillared graphite composite for stabilizing battery anodes

open access: yesScientific Reports, 2022
Nanostructured TiO2 and SnO2 possess reciprocal energy storage properties, but challenges remain in fully exploiting their complementary merits. Here, this study reports a strategy of chemically suturing metal oxides in a cushioning graphite network ...

A general characterization method for nonlinearities in superconducting circuits

open access: yesNew Journal of Physics, 2019
Detailed knowledge of nonlinearity in superconducting microwave circuits is required for the optimal control of their quantum state. We present a general method to precisely characterize this nonlinearity to very high order.

Is there a shift to “active nanostructures”? [PDF]

open access: yesJournal of Nanoparticle Research, 2009
It has been suggested that an important transition in the long-run trajectory of nanotechnology development is a shift from passive to active nanostructures. Such a shift could present different or increased societal impacts and require new approaches for risk assessment.

Ferromagnetic resonance and interlayer exchange coupling in magnetic multilayers with compositional gradients

open access: yesAIP Advances, 2017
Ferromagnetic resonance (FMR) in magnetic multilayers of type F1/f/F2, where two strongly ferromagnetic layers F1 and F2 are separated by a weakly magnetic spacer f with a compositional gradient along its thickness, is investigated.
