Given the major applications of optical random laser in the next generation devices, tissue imaging is proposed in this article by the aid of plasmonic random laser media. For this purpose, we use Rhodamine 6G as the main gain medium and fill it by Gold nanoparticles, Graphene and the mixture of them as random laser […]
The manuscript is about the head-on collision of two dust-ion acoustic solitary waves (DIAS waves) in dusty plasma including inertial ions, negatively charged stationary dust particles and nonextensive electrons. For this purpose, using the extended Poincaré–Lighthill–Kuo (PLK) approach, two Kortwege–de Vries equations with solitonic solutions are derived and then phase shifts of DIAS waves after […]
In this paper, we study the quantum dynamic of the Klein-Gordon particles/antiparticles with generalized Deng-Fan potential. We determine the energy spectra and the corresponding wave function expressed in terms of confluent Heun function using the extended Nikiforov Uvarov method. The influence of the potential parameters on the energy spectra is discussed in details.
In this paper, the role of physical constants in the definition of Planck mass is reviewed. The hidden concepts of Planck base units are then examined in three quantities: Planck length, Planck time or Planck frequency, and Planck mass. In an extension, a new combination of physical constants reveals the hidden nature behind the definition […]
Zeolitic imidazolate framework (ZIF) is a new class of metal organic framework (MOF) with imidazolate ligands as linkers and metal ions as metal centers. A bismuth zeolitic imidazolate framework (Bi-ZIF) was prepared by laser ablation in liquid environment as a physical bottom-up method for the first time. The samples were characterized by Fourier transform infrared […]
CuO thin films were spray-deposited onto a glass substrate and the deposition temperature was varied from 450 to 550 ℃ with 25 ℃ steps. The 450 ℃ deposition temperature was found to be the optimum condition for crystal growth. However, the FESEM images revealed that the grain size increases with raising the deposition temperature. To […]
Metal organic frameworks (MOFs) are new drug delivery systems because they have large surface area, tunable pore sizes, and controlled drug release. In the present work, Zn2(BDC)2(DABCO) MOF is prepared by a quick and simple method. Then, thymol is loaded into MOF (thymol@MOF) and its chitosan (MOF-CH) at room temperature. And finally, the release of […]
FePt3 and CoPt3 compound nanoparticles were studied, magnetically and structurally. Compound ordering in crystal structure of these nanoparticles is formed at 600ºC. Meanwhile, the shape and size of grains are prominent to be controlled. In this work, layers of FePt3 and CoPt3 nanoparticles with thicknesses of respectively 20nm and 10nm were fabricated on Si wafer, […]
In this research, the effect of corona discharge surface modification on surface properties and water purification efficiency of electrospun polyacrylonitrile and thermoplastic polyurethane )PAN/TPU( nanofiber membranes has been investigated. The corona-treated PAN/TPU membranes were studied using field-emission scanning electron microscopy (FE-SEM), Attenuated total reflectance–Fourier transform infrared spectroscopy (ATR–FTIR), water contact angle, detection and enumeration of […]
This article delves into the intricate interplay between quantum information, black hole dynamics, and spacetime emergence. We explore the fundamental phenomenon of quantum entanglement, which challenges traditional distance boundary concepts. The AdS/CFT correspondence is examined, revealing a profound connection between gravitational theories and quantum fields. It also emphasizes the holographic nature of our universe. The […]
This work discusses the synthesis of (Cu-Se) core-shell nanoparticles using a plasma jet, using aqueous solutions of copper and selenium salts as a precursor. The structural properties of the resultant (Cu-Se) core-shell nanostructures were examined using UV, XRD, and SEM. The diameter of the granules with a concentration of 3:7 is 17 nm. Thus, utilising […]
In recent years, extracting water from the air in hot and humid areas has been studied as a clean and optimal way to supply fresh water. In this research, painted steel surfaces were modified by vacuum plasma, and hydrophilic and hydrophobic grooves were made on them in millimeter scale. Then, by building a steam reactor, […]
This work aims to provide an overview of the synthesis and characterization method employed for the Graphene/Cobalt nanocomposite, along with highlighting its applications. In this research, we report the synthesis of Graphene/Cobalt nanocomposite using Two-steps Laser ablation technique. The experiments were performed with the first harmonic (1064 nm, 10 ns, 6 Hz) output of a […]
Nuclear radiation from radioactive elements may cause genetic abnormalities or causes dangerous diseases such as cancer. For this reason, it is essential to measure food contamination with radionuclides, especially seafood prepared from areas contaminated with industrial pollution. In this case, it is necessary to calculate the risk of developing cancer and determine the permissible amount […]
This study provides a comprehensive bibliometric analysis of global research trends in terahertz (THz) generation. Terahertz radiation, which has a frequency between microwaves and infrared regions of the electromagnetic spectrum, has drawn substantial scientific attention because of its unique properties and potential uses in telecommunications, security screening, medical imaging, and material characterization. In order to […]
