TL;DR: MoS2 sheets show high elasticity and an extremely high Young's modulus, which make them a potential alternative to graphene in applications requiring flexible semiconductor materials.
Abstract: We fabricate freely suspended nanosheets of molybdenum disulphide (MoS2) which are characterized by quantitative optical microscopy and high-resolution friction force microscopy We study the elastic deformation of freely suspended nanosheets of MoS2 using an atomic force microscope The Young’s modulus and the initial pretension of the nanosheets are determined by performing a nanoscopic version of a bending test experiment MoS2 sheets show high elasticity and an extremely high Young’s modulus (030 TPa, 50% larger than steel) These results make them a potential alternative to graphene in applications requiring flexible semiconductor materials PACS, 7361Le, other inorganic semiconductors, 6865Ac, multilayers, 6220de, elastic moduli, 8140Jj, elasticity and anelasticity, stress-strain relations

TL;DR: In the ceramic-inlay models, the greatest von Mises stress was observed on the lateral walls, vestibular and lingual, of the cavity, and indirect resin-composite inlays performed better in terms of stress dissipation.

TL;DR: In this paper, a composite model has been developed in which water ingress may be estimated by changes in overall elastic behaviour of the polymer, and the composite model gives values of the coefficient of diffusion, D, for the bulk adhesive in satisfactory agreement with those obtained by gravimetric analysis.

TL;DR: Contrary to previous reports on ensembles of gold nanorods, it is found that the single particle elastic moduli agree well with bulk values.
Abstract: We present the first acoustic vibration measurements of single gold nanorods with well-characterized dimensions and crystal structure The nanorods have an average size of 90 nm × 30 nm and display two vibration modes, the breathing mode and the extensional mode Correlation between the dimensions obtained from electron microscope images and the vibrational frequencies of the same particle allows us to determine the elastic moduli for each individual nanorod Contrary to previous reports on ensembles of gold nanorods, we find that the single particle elastic moduli agree well with bulk values
