5-[Substituted]-1, 3, 4-thiadiazol-2-amines: Synthesis, Spectral Characterization, and Evaluation of their DNA Interactions
One of the most important aspects of the manufacture of medicinal drugs is the synthesis of novel thiadiazoles. Current medicinal chemistry research has focused on the properties of new compounds with possible…
New Methods for Solution Systems of Linear Partial Differential Equation of the First Order
A new method for solving first-order systems of linear partial differential equations has been proposed. We use methods for reducing several matrices at the same time. This can often lead to an…
Equilibrium Properties of Coulomb Glass
The equilibrium properties of Coulomb glass in two and three dimensions are discussed in this paper. To obtain various thermodynamic properties, we used Monte Carlo simulation. The device is annealed from a…
Swelling Studies of PVA/Gelatin Hydrogels Synthesized Using Gamma Irradiation Technique
The aim of this study was to use the gamma irradiation technique to create various compositions of PVA/gelatin hydrogels. PVA and gelatin aqueous solutions with equal concentration were mixed in various weight…
An Efficient Oxone-Mediated Esterification of Aldehydes Using Indium(III) Triflate
Indium has the atomic number 49 and is found in group 13 of the periodic table of elements. Indium is a chemical element that belongs to the post-transition metals group. Indium has…
Emphasizing the Impact of Experiments in Physics Lessons – “Why, When, How Often?”
Science teaching and learning are incomplete without practical practises. The majority of school laboratories nowadays are well-equipped with experimental instruments and computer-based experimentation systems (Vernier, Pasco). Our main research question is whether…
Recent Study on Synthesis of Novel Pyrimido Oxazine and Their Derivatives
The present study used chalcone and urea as starting materials to make novel oxazine (1). The resulting compound 6-(4-chlorophenyl)-4-phenyl-6H-1,3-Oxazin-2-amine(2) was further reacted with ethyl 2-cyano-3,3-bis (methylthio) acrylate in DMF under reflux conditions,…
Copper Cold Gas-Dynamic Spray Processing for Highly Effective Antipathogenic Coatings: An Integrated Microstructural, Mechanics, and Materials Chemistry Perspective
The motivation for this endeavour is to gain a better understanding of microstructural characteristics, materials surface and bulk chemistry, as well as properties of cold sprayed traditional copper and nanostructured copper coatings…
Understanding the Basic Metallurgy of Duplex Stainless Steel
To understand the phase stability of ferrite at such elevated temperatures, duplex stainless steels with varying chromium content are taken and heat treated between the temperatures of 900 and 1000°C. Since the…
