This study delves into the phonon spectra, martensitic transformations, and magnetic properties of Ni₂MnGa, Ni₂MnAl, and Pd₂MnZ (Z = Ga, Ge, As) alloys. Focusing on Ni₂MnGa, we observe a martensitic transformation at 202 K, closely related to a pre-transformation phase at 260 K, reflecting the compound's sensitivity to temperature and external influences. Investigations into supercell... Read More

In this study, heterocyclic Schiff base ligands derived from 2-amino-4,6-dihydroxypyrimidine and 2-hydroxy-1-naphthaldehyde (L1) were synthesized. These ligands were used in the synthesis of Fe(III) complexes. The synthesized compounds were characterized using FT-IR, 1H-NMR and UV-Vis techniques for the ligands, and TLC, molar conductivity and magnetic susceptibility measurements for the... Read More

Citrus peel wastes were studied for bioethanol production using the H2SO4 pretreatment method and the fermentation of Saccharomyces cerevisiae. This study investigates the potential of acidic pre-treatment for 3 h at 100 °C to remove D-Limonene. The results obtained from FT-IR analysis confirmed that D-limonene was significantly decreased from 0.21% to below 0.01%. The density of the... Read More

One way to get nutrients from trees and grasses is to transport them through the roots. As plants use their roots, nutrients pass through the xylem. There has been interest in estimating the above nutrient amount to select the required increase in plant body weight. For estimation, we consider a model of the vertical rise of a saline solution in the xylem. We analyze the kinematic changes of the... Read More

In this study, the iron oxide nanoparticles were synthesised by green synthesis technique using lotus seed extract. The phytoconstituents present in the seed extract play a significant role in the fabrication of nanoparticles and act as a stabilizing, reducing and capping agent. The prepared iron oxide nanoparticles were analysed using various techniques such as X–ray diffraction (XRD),... Read More

In this paper, we introduce an approach to increase the integration rate of the p-n-junctions framework of a neutral point-clamped three-level inverter. Framework the approach we consider a heterostructure with special configuration. Several specific areas of the heterostructure should be doped by diffusion or ion implantation. Annealing of dopant and/or radiation defects should be... Read More
