Elastic Properties of Carbon Nanotubes and Nanoropes [PDF]
, 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
Indian 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]
, 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]
Coatings, 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.

Nanoindentation of bone: Comparison of specimens tested in liquid and embedded in polymethylmethacrylate [PDF]
, 2004 Elastic modulus of bone was investigated by nanoindentation using common methods of sample preparation, data collection, and analysis, and compared to dynamic mechanical analysis (DMA: three-point bending) for the same samples. Nanoindentation (Berkovich,

Mechanical Anisotropy in Austenitic NiMnGa Alloy: Nanoindentation Studies
Crystals, 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, (

Modulus on graphs as a generalization of standard graph theoretic quantities
, 2015 This paper presents new results for the modulus of families of walks on a graph---a discrete analog of the modulus of curve families due to Beurling and Ahlfors. Particular attention is paid to the dependence of the modulus on its parameters.
