Amadi-Ikpa Chidi NDUKA — 2026-08-30

Bacterial resistance to water purification processes reflects the capacity of microorganisms to adapt to changing environments, necessitating a critical re-evaluation of bacterial resistance patterns in drinking water. Although sachet drinking water often contains detectable microbial loads, the potential role of inadequate disinfection procedures within quality control units is frequently overlooked. This study investigated ten samples from each of four popular brands of sachet drinking water (Teenerx, Danchiz, Wisdom, and Fountino table water) purchased within the study area in Nigeria. Isolation and enumeration of bacteria were performed using the spread plate technique, while morphological and biochemical characterizations were conducted to identify specific bacterial genera. The results revealed detectable concentrations of non-fastidious bacteria across the samples, with mean total viable counts of 1.0 x 10², 7.0 x 10¹, and 4.5 x 10² CFU/mL for Teenerx, Danchiz, and Fountino table water, respectively, showing statistically significant differences (p < 0.05). The isolated bacteria were identified as Staphylococcus aureus, Staphylococcus epidermidis, and Proteus spp., all of which exhibited sensitivity to chlorine alongside distinct biofilm-forming features. While chlorine susceptibility indicates effective protein denaturation, the expression of biofilm structures serves as a cellular defense mechanism that enhances bacterial persistence in water systems. Although these levels may technically comply with specific baseline colony-forming thresholds, the presence of opportunistic pathogens poses potential public health concerns that warrant strict regulatory oversight. Therefore, this study recommends a comprehensive reassessment of bacterial resistance traits and optimization of disinfection protocols in sachet water production to ensure consumer safety.

Petrogenetic and Geothermobarometric Constraints on the Twin Panyam Volcanoes, Jos Plateau, North-Central Nigeria

Achuenu Ifeanyi — 2026-08-30

The Twin Panyam volcanoes of the Jos Plateau, north-central Nigeria, constitute one of the most prominent centers of Neogene–Quaternary alkaline volcanism within the Benue–Cameroon Volcanic Province. This study integrates petrographic, whole-rock geochemical, and mineral thermobarometric data to constrain the petrogenetic evolution and magmatic conditions of the Panyam volcanic system. Field observations and thin-section analyses reveal porphyritic to intergranular textures dominated by olivine, augite, labradorite, and Fe–Ti oxides, consistent with basaltic to trachybasaltic magma compositions. Whole-rock geochemistry classifies the lavas as alkaline basalts characterized by elevated total alkali contents (Na₂O + K₂O). Mineral-based geothermobarometric estimates yield crystallization temperatures of 800–1,000 °C and pressures of 6–9 kbar, indicating magma storage within upper-mantle to lower-crustal depths. These results suggest that the Twin Panyam volcanoes evolved through fractional crystallization of an alkaline basaltic magma derived from a mildly enriched lithospheric mantle source. Generally, the findings enhance current understanding of post-Miocene volcanic processes on the Jos Plateau and provide insights into its broader geodynamic connection with the Cameroon Volcanic Line.

Green and Sustainable Zeolite Synthesis: A Review of Waste-Derived Feedstocks and Energy-Efficient Methods

Piyumi Wathsala Kumari — 2026-08-30

Conventional zeolite manufacturing incurs escalating environmental and economic costs driven by costly reagent-grade precursors, energy-intensive autoclaved heating, and organic structure-directing agents requiring high-temperature calcination, which collectively generate significant waste and emissions. To address these issues, zeolites—defined as crystalline microporous aluminosilicates with well-defined pore architectures that underpin their widespread industrial utility as catalysts, adsorbents, and ion exchangers—are the focus of recent advancements. This review critically examines green and sustainable synthesis by focusing on two interconnected strategies: waste-derived aluminosilicate feedstocks such as coal fly ash, volcanic ash, kaolin, and waste glass as sustainable silica and alumina sources; and energy-efficient synthesis routes including microwave-assisted, solvent-free, and seed-assisted methods that dramatically lower crystallization time and energy consumption. Furthermore, the review analyzes the vital roles of alkaline fusion pre-treatment, structure-directing agents, Si/Al ratios, and gel compositions in precisely controlling framework type and crystallinity under sustainable constraints. Ultimately, a comprehensive comparative assessment of all major synthesis routes is provided alongside future research directions aimed at achieving scalable, template-free, and waste-valorizing zeolite production.
