- Introduction
Food quality assurance is becoming increasingly important in food processing industries as expectations from the consumers and competitions among food manufacturers continue to grow. Thus there is an increasing research interest in the area with a view to ensure safety products of foods. Honey, a natural viscous food which is well known for its high nutritional and medicinal...
- Introduction
Soft drink is a non-alcoholic beverage that typically contains carbonated water, a sweetener and a natural or artificial flavouring agent and any other additives such as caffeine, colorant, preservatives etc. However, the level of sugar in drinks plays a vital role in our bodies and as such determination of its level will never be over emphasized. Brix value depicts the sugar...
This study investigates the influence of plasma screening on the relativistic behavior of a hydrogen-like atomic system through the application of a screened Coulomb potential. By accurately solving the Klein-Gordon equation in spherical coordinates, under the assumption that the scalar and vector potentials are equivalent, we get the self-energy spectrum of our system along with its...
We study the non relativistic case of a Hydrogen-like atoms in a plasma environment. We use the screened Coulomb potential to model the phenomenon and we write an almost analytical formula for the energies for large wave lengths. We give also a method to compute the critical value of the wave numbers that ionize the atoms.

Improved Dy3+ + Sm3+ co-doped strontium magnesium borate glasses with the nominal compositions of 20SrO 10MgO (70 z) B2O3 0.7Dy2O3 ...
In order to implement the process of quantum teleportation, we evaluate quantum information resources through local quantum uncertainty, local quantum Fisher information, and quantum entanglement, as measured by the concurrence of the teleported output state. One of the main challenges of this work lies in the ability to create and analyze local non-classical correlations between the proposed...
Silicon nanoparticles of 2-10 nm size (Si-np) embedded into silicon nitride (Si3N4) thin films (70 nm thick) were synthesized and deposited on polycrystalline silicon wafers through plasma enhanced chemical vapour deposition (PECVD) technique using ammonia (NH3) and silane (SiH4) as precursor reacting gases. A second layer (50 nm) consisting of rare-earth neodymium oxide (Nd2O3) was added...

X-ray detectors play a crucial role in various fields, from medical imaging to high-energy physics. This study focuses on the simulation of both direct and indirect X-ray detectors using the Geant4 toolkit, a Monte Carlo-based software widely used for particle-matter interactions. The direct detector simulation models the immediate conversion of X-rays into electrical signals, while the...
We present Fourier–Bessel particle-in-cell (FBPIC) simulation results from a laser wakefield electron accelerator driven by Gaussian (G) and Bessel-Gauss (BG) laser beam. The particle-in-cell simulations show that electron bunch energies of tens of MeV can be obtained, within cm distances to obtain a high-quality beam with low energy spread and low slice emittance.
In this study, we conducted a computational optimization of four designs for CsSnBr3 perovskite solar cells using the SCAPS-1D simulation tool. We explored how variations in the thicknesses of the electron transport layer (ETL), hole transport layer (HTL), and perovskite layer, as well as changes in temperature, series and shunt resistances, and the acceptor doping density of the HTL,...
Abstract
According to Corpinot and Bučar, any reasonable improvement of the physics and chemistry of the solid state requires a theory of molecular packing [1]. In line with this, authors of this study report how lattice theory explains the crystal packing of N, N’-bis(4-chlorophenyl)thiourea N, N- dimethylformamide [2]. Here, we explore the type of crystal packing of the resulting lattice...
- Introduction
In nuclear reactors, the release of gases from fission products and the accumulation of light and heavy atoms, such as helium, hydrogen and xenon, during operation can significantly alter the structural integrity of reactor materials [1]. These gases may migrate and cluster, forming gas bubbles and inducing stress, which leads to defects within protective layers like...
Manganese steel is a high-carbon alloy known for its exceptional toughness, ductility, and wear resistance. A high manganese grades comprising approximately 22-44% manganese and 1% carbon, exhibits remarkable work-hardening properties, making it ideal for high-impact applications. While the metal grade specification does not indicate any chromium and molybdenum elements, these were found in...

Defect complexes have a significant impact on the structural, electronic, optical and electrical properties of semiconductors. Several defect complexes formed by n-type and p-type atoms in Ge have been implemented for the development of improved modern microelectronic devices. However, there is no reported study on the substitutional-interstitial defect complexes formed by trivalent atoms in...

Abstract
It has been shown that lycopene molecules have a substantial nonlinear optical third order susceptibility, ꭓ(3), because of their double bond conjugated electronic structure. It is demonstrated that natural Lycopene has a markedly higher 3rd order nonlinearity, ꭓ(3), as high as 2.65 10−6 esu, the highest value of any natural phytocompound studied to date, including β-carotene [1]....
