In this paper, we consider the derivation of the modified Wenzel’s and Cassie’s equations for wetting phenomena on rough surfaces from a three-dimensional phase field model. We derive an effective boundary condition by asymptotic two-scale homogenization technique when the size of the roughness is small. The modified Wenzel’s and Cassie’s equations for the apparent contact angles on the rough s...

This article reports the effects of gamma irradiation (dose ranges 0.1-10 kGy from 60Co source) on the characteristics of solid gelatin and the physico-mechanical, microstructural and bioactive properties of the scaffold prepared from irradiated gelatin solution. FTIR, intrinsic viscosity, bloom strength, thermal properties, SEM, tensile properties, water uptake ability and antimicrobial activi...

We investigate, using the framework of Γ-convergence, a phase-field model proposed in [Torabi et al, Proc. R. Soc. A, 2009] for strongly anisotropic systems; in particular, we prove a full Γ-convergence result for an anisotropic Modica-Mortolatype energy.

objective: to assess relative biological effectiveness (rbe) of 131i radiation relative to 60co gamma rays in glioblastoma spheroid cells. materials and methods: in this experimental study, glioblastoma spheroid cells were exposed to 131i radiation and 60co gamma rays. radiation induced dna damage was evaluated by alkaline comet assay. samples of spheroid cells were treated by radiation from 13...

Study has been made of the thermoluminescence (TL) response of silica-based Ge-doped cylindrical, flat and photonic crystal fibres (referred to herein as PCF-collapsed) to electron (6, 12 and 20 MeV) and photon (6, 10 MV) irradiation and 1.25 MeV γ-rays, for doses from 0.1 Gy to 100 Gy. The electron and photon irradiations were delivered through use of a Varian Model 2100C linear accelerator lo...

In this study, Acrylamide (AAM), Itaconic acid (IA) and nano TiO2 were copolymerized using gamma irradiation with 60Co γ-rays at a dose of 25 KGy to form poly (acrylamide-co-Itaconic acid/TiO2) (P(AAM-co-IA/TiO2)). Different compositions P(AAM-co-IA/TiO2) nanocomposites are prepared examined for Ce(III) sorption. The optimum composition is C6P(AAM-co-IA/TiO2); 61.54 AAM: 30.77 IA: 2.56 TiO2: 5....
