Electrochemical Energy Storage Studies on Sustainably Synthesized Co3O4 Nanoparticles for Supercapacitor Electrodes

Helen Osora, T. Jebakumar Immanuel Edison, David Kolkoma, Gabriel Anduwan, Mathew Waimbo, Senthilkumar Velusamy

November 2025: 1-13 DOI: 10.55121/nefm.v4i2.689

560 (Abstract) 400 (Download) PDF

In this study, a facile hydrothermal technique was used, and the commercially important cobalt oxide nanoparticles were synthesised for pseudocapacitor electrodes in supercapacitor applications. The prepared particles were subjected to different characterization techniques to determine their phase structure, topography, and elemental composition by XRD, FE-SEM, TEM, and EDAX. The XRD pattern confi... more

Morphology and Functional Behavior of Polyacrylamide Hydrogels Reinforced with Sustainable Montmorillonite Nanoclay

Abayomi I. Adeleke, Jonathan R. Sanders, Pedro E. Arce

November 2025: 43-54 DOI: 10.55121/nefm.v4i2.747

706 (Abstract) 231 (Download) PDF

Polyacrylamide (PAAM) hydrogels are widely used in electrophoretic separations of proteins, deoxyribonucleic acid (DNA), and cells due to their high resolving power, optical and ultraviolet (UV) transparency, electro-neutrality, and tunable pore structure. Incorporation of nanomaterials into PAAM gels has been proposed as a strategy to further tailor gel microstructure and transport properties. In... more

Effects of Bentonite Nanoplatelets and Low Magnetic Field Intensity on the Pore Structure of Polyacrylamide Gel

Abayomi I Adeleke, Mustafa M. Rajabali, Jonathan R Sanders, Pedro E. Arce

November 2025: 55-67 DOI: 10.55121/nefm.v4i2.782

395 (Abstract) 165 (Download) PDF

This study investigates the effects of low-intensity magnetic fields and nanoplatelet incorporation on the structure and transport behavior of polyacrylamide (PAAM) gel matrices. Gel nanocomposites containing environmentally benign montmorillonite (MMT) nanoplatelets were prepared under controlled magnetic field orientations during gelation and compared with pure PAAM reference gels. The resulting... more

Synthesis and Antimicrobial Properties Pectin + CuNi Films and Characterization by Scanning Electron Microscopy

Yamila Illanez, Corina Cangiano, Yesica Sabrina Lambrese, Cecilia Fernandez, Marcelo Ricardo Esquivel, Maria de los Ángeles Cangiano

November 2025: 68-78 DOI: 10.55121/nefm.v4i2.711

217 (Abstract) 185 (Download) PDF

The synthesis of pectin-based films containing nanoparticles of CuNi (NPs), with potential antimicrobial properties, as an active solid is presented in this work. The NPs were dispersed in pure pectin to be used as food packaging in the food industry. The samples obtained were laid flat to characterize the sample thickness. The goal of this work is to find appropriate electron microscopy technique... more
