Abstract: For present work, we are reporting a study on structural and dielectric properties of lead zirconate titanate and nickel zinc ferrite (PZT-NZF) composite having compositional formula 0.9PbZr_0.65Ti_0.35O₃ – 0.1Ni_0.8Zn_0.2Fe₂O₄ synthesized by solid state reaction route using microwave sintering. The composite sample was sintered at 1150^oC for 10 minutes. The presence of two phases (PZT and NZF) was confirmed by using x-ray diffraction technique. Experimental density of sintered pellet was calculated using Archimedes principle. Dielectric properties were studied as a function of temperature (35-500^oC) at 1, 10 & 100 kHz frequency and function of frequency (100 Hz- 1 MHz) at room temperature.

Keywords: Dielectric; Diffraction; Ferroelectric; Ferrite; microwave.

Abstract: Natural fiber from plant was chemically treated to expose the cellulose contents that gave stronger bonding during reinforcement for composite production. Chemical treatment of Kankan bile fiber was done using three different alkaline solutions; Potassium Hydroxide, Nitric acid, and Acetic anhydride. Optimization of process variables was done to get the optimum condition of the process and model equation was developed. The result showed that nitric acid gave the lowest value of 23.81% lignin removal at 10% concentration, 70minutes and 40^OCand highest  value of 44.19% removal at 14% concentration, 50minutes and 70^OC while Acetic anhydride gave the lowest value of  33.21% lignin removal at 10% concentration, 70minutes and 40^OCand  highest value of 46.3995% removal at 14% concentration, 50minutes and 70^OC. Also, Potassium hydroxide gave the lowest value of 29.89% lignin removal at 6% concentration, 90minutes and 50^OCand highest value of 41.24% removal at 14% concentration, 50minutes and 70^OC. Hence, acetic anhydride was the best chemical to removal lignin from Kankan bile fiber.

Abstract: Northern Nigeria faces acute electricity challenges due to weak grid infrastructure, transmission losses, water scarcity, and rising energy demand from population growth and industrialization. Renewable energy sources such as solar and wind, though abundant, are intermittent and insufficient to meet baseload requirements. In this context, Small Modular Reactors (SMRs) have emerged as a promising solution due to their modularity, safety features, scalability, and compatibility with hybrid energy systems. This study applied the Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS), a multi-criteria decision-making (MCDM) method, to evaluate and rank four SMR technologies Light Water Reactor SMR (LWR-SMR), High Temperature Gas-Cooled Reactor SMR (HTGR-SMR), Molten Salt Reactor SMR (MSR-SMR), and Sodium-Cooled Fast Reactor SMR (SFR-SMR). Fourteen decision criteria were developed based on Nigeria’s energy context, the results showed that LWR-SMR ranked highest (closeness coefficient = 0.5693), owing to its high technology readiness, proven commercial deployment, and financing maturity. HTGR-SMR ranked second (0.5575), excelling in water efficiency and renewable integration, which are vital in Northern Nigeria’s arid climate. In contrast, SFR-SMR (0.4097) and MSR-SMR (0.3598) ranked lower due to technological immaturity, higher complexity, and limited financing pathways. The study concludes that LWR-SMR and HTGR-SMR are the most suitable options for first-phase deployment in Northern Nigeria, while advanced designs such as MSR and SFR may be considered in the long term as technology and regulatory capacity evolve.

Abstract: Pharmaceutical residues in municipal wastewater pose a critical environmental and public health challenge, as conventional activated sludge treatment removes less than 50% of many pharmaceutical compounds. This systematic review compares three advanced tertiary treatment technologies: advanced oxidation processes (AOPs), biochar adsorption, and membrane filtration. The comparison evaluates removal efficiency, energy consumption, capital and operational costs, technology readiness level, and transformation product risks. Reverse osmosis and photo-Fenton oxidation achieve the highest removal efficiencies, exceeding 95% across diverse pharmaceutical classes. However, they require substantial energy inputs (1.5 to 6.0 and 0.5 to 2.0 kWh/m³, respectively) and significant capital investment. Biochar adsorption offers the most cost-effective solution for moderate removal targets (70 to 90%) with minimal energy requirements (less than 0.1 kWh/m³), making it particularly valuable for resource-limited settings. Hybrid systems that combine oxidation with biological treatment or adsorption consistently outperform standalone technologies by 10 to 20 percentage points. No single technology dominates across all decision criteria. Technology selection should incorporate treatment objectives, regulatory requirements, budget constraints, and local implementation capacity based on specific context. Future municipal wastewater systems will likely use combinations of technologies rather than relying on single universal solutions.

Keywords: advanced oxidation processes, biochar, pharmaceutical removal, membrane filtration, municipal wastewater treatment, technology comparison.
