Using the Age and Metallicity of 8 Star Clusters to confirm the Chemical Enrichment History of the LMC
(IOP Science, 2019)In this paper, we find the ages and metallicities of 8 Large Magellanic Cloud (LMC) star clusters obtained from integrated light spectra and use them to obtain the Chemical Enrichment History of the host galaxy. Our results ... -
Few-cycle laser driven reaction nanoscopy on aerosolized silica nanoparticles
(Springer Nature, 2019)Nanoparticles offer unique properties as photocatalysts with large surface areas. Under irradiation with light, the associated near-fields can induce, enhance, and control molecular adsorbate reactions on the nanoscale. ... -
B − L violating interactions in supersymmetric SO(10) models
(IOP Science, 2019)An analysis is given of B − L violating interactions in SO(10) arising from the integration of $10+\bar{10}$ of SU(5) of heavy Higgs. The analysis is done within the well defined missing partner model where the doublet-triplet ... -
Can the Full Spectrum Fitting Technique correctly detect Age Spreads in Young Star Clusters?
(IOP Science, 2019)Integrated spectra of star clusters have proven to be accurate tools for obtaining age, metallicity and reddening of extragalactic clusters for which resolved data is not available. In this work we investigate the possibility ... -
Recent Advances in Femtosecond Laser-Induced Surface Structuring for Oil–Water Separation
(MDPI, 2019)Femtosecond (FS) laser-induced surface structuring is a robust, maskless, non-contact, and single-step process for producing micro- and nanoscale structures on a material’s surface, which remarkably alters the optical, ... -
Application of Quasi-Phase Matching Concept for Enhancement of High-Order Harmonics of Ultrashort Laser Pulses in Plasmas
(MDPI, 2019)Novel methods of coherent short-wavelength sources generation require thorough analysis for their further amendments and practical implementations. In this work, we report on the quasi-phase matching (QPM) of high-order ... -
A Simple Model for the Fields of a Chirped Laser Pulse With Application to Electron Laser Acceleration
(Frontiers in Physics, 2019-12)A simple model is introduced for the fields of a chirped laser pulse. As an application, dynamics of laser-acceleration of a single electron by the fields of a pulse, with a sin4 envelope, is investigated. Multi-GeV energy ... -
Investigations of the Co-Pt alloy phase diagram with neutron diffuse scattering, inverse cluster variation method, and Monte Carlo simulations
(American Physical Society, 2020)The short-range order in a CoPt alloy was determined at 1203 and 1423 K using neutron diffuse scattering measurements. The effective pair interactions provided by data analysis reproduce well the experimental order-disorder ... -
Investigation and Optimization of Mxene functionalized Mesoporous Titania Films as Efficient Photoelectrodes
(MDPI, 2021)Three-dimensional mesoporous TiO₂ scaffolds of anatase phase possess inherent eximious optical behavior that is beneficial for photoelectrodes used for solar energy conversion applications. In this regard; substantial ... -
Synthesis and low-order optical nonlinearities of colloidal HgSe quantum dots in the visible and near infrared ranges
(Optical Society of America, 2021)We synthesize colloidal HgSe quantum dots and characterize their nonlinear refraction and nonlinear absorption using a Nd:YAG laser and its second harmonic. The 7.5 nm quantum dots were synthesized using the hot-injection ... -
Influence of gas environment on the dynamics of wetting transition of laser-textured stainless steel meshes
(American Institute of Physics Inc., 2021)We analyze the role of surrounding gas and aging in ambient air in the wettability behavior of laser-processed stainless steel meshes. Laser texturing of meshes was carried out in the presence of different gases (N₂, O₂, ... -
Renormalization functions of the tricritical O(N)-symmetric Φ⁶ model beyond the next-to-leading order in 1/N
(IOP Publishing, 2021)We investigate higher-order corrections to the effective potential of the tricritical O(N)-symmetric Φ⁶ model in 3-2ε dimensions in its phase exhibiting spontaneous breaking of its scale symmetry. The renormalization group ... -
