On behalf of the Editorial Team and Reviewers, I have the great pleasure of presenting this volume 4, issue 3 of the Journal of the Nigerian Society of Physical Sciences (JNSPS) to the research community and the world at large, comprising those seeking to publish their works and those who wish to keep up with the latest findings in their areas of research.
This current edition includes 23 articles by authors from eight different countries: Nigeria, Malaysia, India, UK, Oman, Iraq, Pakistan, Botswana. The papers included in this issue are in the areas of atmospheric physics, nuclear physics, computational mathematics, numerical analysis, atmospheric and environmental physical chemistry, multicollinearity, machine learning, material science, mathematical modelling, graph theory, and distribution.
Some of the useful investigations conducted therein contribute to a fundamental understanding of the effect of graphene materials (GRMs) on the optoelectronic properties of perovskite solar cells (PSCs), and it confirms the promising prospects of achieving low-cost, efficient, and stable PSCs for commercialization with graphene materials. Other findings were found to be useful in providing a perception of the treatment caused by excessive consumption of fatty foods, thereby lowering the risk of cancer, hypertension, and many heart-related diseases. Another study also found that the synthesized ZnO nanoparticles provide antimicrobial efficacy against clinical strains of Bacillus subtilis and Staphylococcus aureus, as well as against standard strains of Escherichia coli. Several fields, including cosmetics and pharmaceuticals, can benefit from biosynthesized nanoparticles.
In general, this issue would be of interest to researchers and practitioners working in related fields, as well as the general public interested in physical sciences.
