Use of Vibrational Optical Coherence Tomography to Analyze the Mechanical Properties of Composite Materials

open access: yesSensors, 2021
Energy storage and dissipation by composite materials are important design parameters for sensors and other devices. While polymeric materials can reversibly store energy by decreased chain randomness (entropic loss) they fail to be able to dissipate ...

Elastic Properties of Carbon Nanotubes and Nanoropes [PDF]

open access: yes, 1997
Elastic properties of carbon nanotubes and nanoropes are investigated using an empirical force-constant model. For single and multi-wall nanotubes the elastic moduli are shown to be insensitive to details of the structure such as the helicity, the tube ...

The theory and art of corneal cross-linking

open access: yesIndian Journal of Ophthalmology, 2013
Before the discovery of corneal cross-linking (CXL), patients with keratoconus would have had to undergo corneal transplantation, or wear rigid gas permeable lenses (RGPs) that would temporarily flatten the cone, thereby improving the vision.

Saddle-splay modulus of a particle-laden fluid interface [PDF]

open access: yes, 2008
The scaled-particle theory equation of state for the two-dimensional hard-disk fluid on a curved surface is proposed and used to determine the saddle-splay modulus of a particle-laden fluid interface.

Comparative Study on Complex Modulus and Dynamic Modulus of High-Modulus Asphalt Mixture [PDF]

open access: yesCoatings, 2021
In the French high-modulus asphalt mixture design system, the complex modulus of the mixture under the conditions of 15 °C and 10 Hz is taken as the design index. However, in China, the dynamic modulus under the conditions of 15 °C, 10 Hz, 20 °C, 10 Hz and 45 °C, 10 Hz was taken as the stiffness modulus index of high-modulus asphalt mixture.

Mechanical Anisotropy in Austenitic NiMnGa Alloy: Nanoindentation Studies

open access: yesCrystals, 2017
: Mechanical anisotropy in an austenitic ferromagnetic shape memory alloy (SMA), Ni50Mn26.25Ga23.75, is investigated along (010), (120), (121), (231) and (232) using nanoindentation. While (010) exhibits the highest reduced modulus, Er, and hardness, H, (

Origins of elastic properties in ordered nanocomposites [PDF]

open access: yes, 2004
We predict a diblock copolymer melt in the lamellar phase with added spherical nanoparticles that have an affinity for one block to have a lower tensile modulus than a pure diblock copolymer system.

Modulus Computational Entropy [PDF]

open access: yes, 2013
The so-called {\em leakage-chain rule} is a very important tool used in many security proofs. It gives an upper bound on the entropy loss of a random variable $X$ in case the adversary who having already learned some random variables $Z_{1},\ldots,Z_ ...

Effective Elastic Modulus of Wavy Single-Wall Carbon Nanotubes

open access: yesC, 2023
A simple method for determining the effective elastic modulus of wavy single-wall carbon nanotubes (SWCNTs) is presented in this paper. The effective modulus of curved SWCNTs is derived using Castigliano’s theorem.
