Unveiling the Influence of natural weathering on the nanomechanical properties of magnetorheological elastomers

Results in Engineering
Examining the physical aging of materials is essential for assessing their long-term performance and determining their suitability for specific applications. Material aging involves changes from their initial state, including deterioration or degradation.

Recent Development of Nanomechanical Property Measurement

Nihon Reoroji Gakkaishi, 2008
Nanomechanical mapping by atomic force microscopy (AFM) has been developed as the useful application to measure the physical properties of soft materials at nano-meter scale. To date, the Hertz theory was used for analyzing force-distance curves as the simplest model of contact mechanics between elastic bodies. However, the preexisting methods based on

Quantum Properties of a Nanomechanical Oscillator

, 2006
We study the quantum properties of a nanomechanical oscillator via the squeezing of the oscillator amplitude. The static longitudinal compressive force $F_0$ close to a critical value at the Euler buckling instability leads to an anharmonic term in the Hamiltonian and thus the squeezing properties of the nanomechanical oscillator are to be obtained ...

Deciphering the spatial and microstructural landscape in subchondral bone remodeling of temporomandibular joint osteoarthritis

Materials & Design
The pathological remodeling of subchondral bone is a hallmark of osteoarthritis (OA), yet the spatial heterogeneity and dynamic evolution of its microstructural, compositional, and nanomechanical properties remain poorly understood.

4.1 PROBING ARTERIAL STIFFNESS AT THE NANO-SCALE USING THE INTERNAL MAMMARY ARTERY AS A NOVEL TARGET

Artery Research, 2018
Introduction: Arterial stiffening is associated with structural and biomechanical alterations in the aorta. However, there are still gaps in our understanding as to how the structure and properties of arteries across the vasculature are altered with high
