In this study, thermal Casimir-Polder potential is calculated for an atom in the presence of a dielectric sphere using the formula given in terms of the Green’s function. Then, the limiting cases of large and small sphere are investigated. In the limiting case of a large sphere, the formula of thermal potential for an excited atom in the presence of a dielectric half-space and then a perfectly ...
In this paper, we construct the Gazeau-Klauder coherent states of a two- dimensional harmonic oscillator on a sphere based on two equivalent approaches. First, we consider the oscillator on the sphere as a deformed (non-degenerate) one-dimensional oscillator. Second, the oscillator on the sphere is considered as the usual (degenerate) two--dimensional oscillator. Then, by investigating the quan...
The application of nano drug delivery systems, particularly those utilizing natural bioactive compounds with anticancer properties, has gained significant attention. In this study, a novel nano-phytosome-loaded phenolic rich fraction (PRF) derived from Allium ampeloprasum L. was developed. antitumor activity the formulation evaluated in BALB/c mice TUBO colon carcinoma. PRF-loaded nano-phytosom...
see through the wall radar, is a relatively new small range radar that uses electromagnetic waves to detect targets behind wall. because of its symmetry, a conducting sphere is often used as a reference scatterer to calibrate radars. in this paper, to simulate received signal for see through the wall radar, scattering model of a conducting sphere in free space is presented. then using a dielect...
nowadays, the use of innovative nano-technology in the food industry quality control has significantly increased and it is widely employed in numerous fields such as diagnosis of microbial toxin of foods using nano-biosensors, increasing food shelf-life with the help of nano-clay and nano-silver packaging, as well as changing some of the unpleasant organoleptic properties such as taste, color, ...
Abstract Transfer printing based on switchable adhesive that heterogeneously integrates materials is essential to develop novel electronic systems, such as flexible electronics and micro LED displays. Here, we report a robust design of thermal actuated dry adhesive, which features stiff sphere embedded in thermally responsive shape memory polymer (SMP) substrate encapsulated by an elastomeric m...
We study the properties of a hard-sphere dense gas near the hard walls of micro and nano-channels. Analytical techniques, Monte Carlo (MC) methods and molecular dynamics (MD) simulation methods have been used to characterize the influence of the characteristic parameters such as number density, reduced density, width of the system and molecular diameter, on the equilibrium properties of the gas...
