Summary: This study systematically varied the feed composition to synthesize polyaniline (PANi) and polyaniline-clay nanocomposites (PACN), and analyzed their thermal properties. The results showed that increasing the oxidant concentration decreased the thermal stability and melting point of PANi, while the reinforcement of PANi with clay increased its thermal stability and melting point. The optimal thermal stability and melting point of PANi were achieved by adding about 0.1 wt% of the oxidant.

Summary: The biosynthesis of copper oxide nanoparticles (CuONPs) using Halymenia dilatata seaweed aqueous extract was investigated. The biosynthesized CuONPs were characterized using UV, FTIR, XRD, SEM, EDAX, HRTEM, and zeta potential analysis. The results showed that the CuONPs had maximum absorbance at a wavelength of 270 nm and had a crystalline structure. Flavonoids and phenolic compounds in the CuONPs were found to reduce Cu2+ ions. The CuONPs exhibited spherical shape with a diameter of 60 nm and showed strong antimicrobial activity against human pathogenic bacteria, particularly B. subtillis, S. aureus, and K. pneumoniae. Furthermore, the CuONPs displayed significant anticancer activity against HeLa cell line with an IC50 value of 147.51 lg/ml after 48 hours of treatment.

Summary: Cobalt-nickel mixed ferrite (CNFO) and gadolinium doped cobalt-nickel mixed ferrite (G-CNFO) materials were synthesized using the microemulsion technique. The physicochemical features of the materials were examined, and G-CNFO showed better photocatalytic activity than CNFO under visible light. The optimal parameters for G-CNFO's catalytic properties were investigated, and its enhanced photocatalytic activity was attributed to its tuned band structure, high light harvesting abilities, reduced electron-hole recombination, and nanostructured morphology.

Summary: This study focuses on hydrogen production through electrocatalysis using a newly synthesized and characterized nano-hybrid composite electrocatalyst. The electrocatalyst consists of mixed metal oxides and reduced graphene oxide. Various characterization techniques were used to evaluate the structural and morphological characteristics of the electrocatalyst. Electrochemical methods, including linear sweep voltammetry, Tafel slope, and electrochemical active surface area measurements, provided valuable insights into the catalytic efficiency and effectiveness of the electrocatalyst for the hydrogen evolution reaction. The findings demonstrate that the electrocatalyst WO3-CuO/rGO exhibits exceptional catalytic efficiency, with a current density of 200 mA/cm2 at an overpotential of -400 mV, a Tafel slope of 44 mVdec(-1), and low charge transfer resistance. Furthermore, chronoamperometric analysis confirms the electrocatalyst's durability and potential for practical applications.

Summary: Electrocatalytic water splitting is a promising approach for massive hydrogen production, but the development of an active, stable, and low-cost electrocatalyst is challenging. MXene has shown potential as an electrocatalyst, but its poor stability and synthesis routes hinder its application. In this study, we synthesized MXene and its composites with CoNiFe2O4 using an acid-free wet chemical approach for efficient water splitting. We used a layer-by-layer assembly approach to prevent restacking of MXene flakes and achieved high electrocatalytic performance. The catalyst showed good overpotentials and high electrochemical stability, surpassing many reported catalysts. This study provides insights into the design of low-dimensional electrocatalysts for water splitting.
