Abstract Cancer therapy necessitates the development of novel and effective treatment modalities to combat complexity this disease. In project, we propose a synergistic approach by combining chemo-photothermal using gold nanorods (AuNRs) supported on thiol-functionalized mesoporous silica, offering promising solution for enhanced lung cancer therapy. To begin, MCM-41 was synthesized surfactant-templated sol–gel method, chosen its desirable porous structure, excellent biocompatibility,...
In this work, the effects of size and wetting layer (WL) on subband electronic envelop functions, eigenenergies, linear nonlinear absorption coefficients, refractive indices a dome-shaped InAs/GaAs quantum dot (QD) were investigated. our model, dome InAs QD with its WL embedded in GaAs matrix was considered. A finite height barrier potential at interface assumed. To calculate envelope functions effective one-electronic-band Hamiltonian electron mass approximation used. The optical properties...
The increase in global demand consumption of sesame seeds as a nutritious food source and the limited areas suitable for cultivation have made world face challenge determining optimal storage conditions seeds.

A fraction of the fundamental beam energy deposited into nonlinear crystals to generate second harmonic waves (SHW) causes a temperature gradient within crystal. This inhomogeneity can alter refractive index medium leading well-known effect called thermal dispersion. Therefore, generated SHW suffers from lensing and longitudinal phase mismatching. In this work by coupling heat equation with generation (SHG) formalism applied type-II configuration along walk-off effect, we investigate...

A strong dependence P-to-S transition energy, dipole moment, oscillator strength, linear third-order nonlinear susceptibilities concluded. moment was shown to be purely in-plane polarization. absorption dispersion showed a red shift when increased. Our results revealed that...
In this work, the effects of shape and size on intersubband electronic optical properties three-dimensional self-assembled pyramid-shaped InAs/GaAs quantum dots (QDs) were investigated in detail. More precisely, in-plane- z-polarized transitions dipole moment (TDM), oscillator strength (OS), absorption coefficients P-to-S, WL-to-P, WL-to-S studied as a function QD height. The P-to-S TDM showed to be strong purely in-plane-polarized transition dominating two others. However, TDMs OSs WL-to-P...
In this article, we propose a class of high-performance and low-loss waveguide by exploiting the hybridization plasmon-phonon modes through coupling graphene with hexagonal boron nitride (hBN). It is found that inserting an ultra-thin hBN layer hyperbolicity behavior between thin low-index substrate leads to squeezing light into hBN, enabling propagation as compared traditional graphene/substrate plasmonic waveguide. Furthermore, results show choosing appropriate values for physical...
