The main purpose of cementing of the well is to provide effective zonal isolation for the entire life of wells. The standard cements cannot prevent loss of zonal isolation when the stress level in the well cement is severely fluctuated. Since elastic cements improve elastic properties, recently, a number of studies have been done in this area. For this purpose, a nanoparticle, named EX-RIPI, wa...

Elastic deformation on the surfaces of molecular crystals can be imaged using a variant of lateral force microscopy in which the tip is scanned parallel to the cantilever axis. The shear force transverse to this direction has a distinctly different origin than the friction force as determined by the tip velocity and temperature dependence of the cantilever torque. An elastic deformation model f...

Several analytical approaches can be utilized to estimate the elastic properties of polycrystalline silicon. In experimental studies, notion an macroscopically isotropic aggregate is introduced while single crystals obey cubic symmetry. We here give a synopsis on predict and apply them effective parameters Here, predictions are based associated with shear solely. The results juxtaposed in terms...
