In pursuing sustainable bio-economy and bio-refinery advancements, enzymatic hydrolysis plays a pivotal role in converting starch-based feedstock into valuable products. Amylase, an enzyme crucial for starch hydrolysis, faces challenges in stability and reusability in industrial applications. This study explores the Immobilization of amylase on alginate to enhance enzyme stability and...

In this study, the optimal process conditions for the production of biodiesel from Gmelina arborea seed oil were investigated using the transesterification method. The impacts of process parameters such as catalyst concentration, reaction time, reaction temperature, methanol/sample ratio, and agitation speed were investigated separately and, in a matrix, to determine synergistic relationships....

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...

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...

This work is on developing a database for drying parameters of some Nigerian fruit crops: banana, guava, and plantain. Experimental data was collected and stored in a database. A relational database for drying parameters of three foodstuffs was developed using Microsoft Structured Query Language Server(MS SQL) 2012 database management system and Microsoft Visual Studio.Net 2013 framework was...

Every material in its various forms of existence possesses specific property and applications in various fields. In the similar way metamaterials are those hypothetical and expert to possess a specific property and applicable to various domains. These materials are engineered artificially with specific structures designed to exhibit the properties which are not available in naturally occurring...

In this study, the laboratory data of an experimental paper on separating the food process by ultrafiltration was used and entered as the input experimental data for the MLP multi-layer neural network modeling. The operating parameters were pressure, time, frequency, and flux. According to the created results and the regression coefficient R2 and MSE values evaluation, the Levenberg-Marquart...

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...

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...

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),...

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...

The novelty and the improved plagiarism of research work are significant for academic integrity. The study aimed to investigate the relationship between improved plagiarism levels and the novelty of academic research work using a linear regression model. The study tested the research work of 202 postgraduate students from Enugu State University of Science and Technology-ESUT in 2020-2023 academic...
