Summary: Yttrium oxide/CuO nanocomposite with different concentrations of Y2O3 were synthesized and investigated for their structural, morphological, and photocatalytic properties. The nanocomposite exhibited a porous morphology with significant aggregation and showed efficient photocatalytic degradation of both carmine and methylene blue. The results indicated that UV light had a more pronounced effect on the reaction rate compared to visible light, and carmine was degraded faster than MB. The nanocomposite also demonstrated stability over repeated use.

Summary: In this study, sulfide and chloride ions were successfully doped into ZnO through hydrothermal method. The doped ZnO nanostructures showed no significant change in morphology, retaining the wurtzite crystal structure with a red shift in XRD results. The successful doping of sulfide and chloride ions was confirmed by elemental analysis. Importantly, the optical band gap of ZnO was reduced upon doping, leading to enhanced photocatalytic properties. The doped ZnO photocatalyst achieved a high photo-degradation efficiency of methylene blue.

Summary: Zinc oxide nanoparticles were successfully synthesized using glycine nitrate solution combustion synthesis. The synthesized nanoparticles exhibited a pure hexagonal wurtzite-like structure of ZnO. They showed effective visible light catalytic activity in the degradation of methylene blue dye, degrading 98% of the dye in 120 minutes with 0.1 g/L of catalyst loading. Photoluminescence studies suggested that the enhanced photocatalytic activity may be attributed to the presence of singly ionized oxygen vacancy or intrinsic defects.

Summary: CeO2/CuO nanocomposites were prepared using the solution combustion technique with urea as the fuel. The materials were characterized using various techniques, including XRD, FT-IR, UV-Vis spectroscopy, and PL. The CeO2/CuO nanocomposites showed cubic and monoclinic phases, with average crystallite sizes of 5.16 nm, 13.87 nm, and 10.36 nm for CeO2, CuO, and CeO2/CuO respectively. The FTIR analysis confirmed the presence of metal-oxygen stretching and other bonds. The band gap values were determined, and the photoluminescence spectra showed UV emissions. The surface morphology of the nanocomposites was observed using FE-SEM, and the elemental composition was confirmed using EDAX. The nanocomposites exhibited significant antimicrobial activity against both gram-positive and gram-negative bacteria. The photocatalytic activity of the nanocomposites was also investigated for the degradation of methylene blue under visible light irradiation.

Summary: Wastewater from the textile industry, which contains various organic dyes, poses a chronic and hazardous problem for human health. A study conducted on the treatment of this wastewater using low-cost and efficient photocatalyst technology found that ZnO microstructures grown in the presence of psyllium husk showed enhanced photocatalytic activity towards the degradation of methylene blue. The psyllium husk modified the surface of the ZnO microstructures, created defects in the crystal structures, and altered the morphology of the nanostructured material. The addition of carbon from the thermal combustion of psyllium husk further improved the photocatalytic performance. The research also explored the optimal dosage of photocatalyst for efficient photodegradation of methylene blue.

Summary: Cu2WS4 nanoparticles were successfully synthesized through solvothermal decomposition using a heterobimetallic single source precursor, WCu2S4(PPh3)(3). The precursor WCu2S4(PPh3)(3) was characterized using multinuclear NMR spectroscopy, while Cu2WS4 nanoparticles were characterized by powder X-ray diffraction (PXRD) with Rietveld refinement. Additionally, FESEM and EDAX analyses were performed to assess the morphology and composition of Cu2WS4. Electrochemical studies in acidic and basic media showed that Cu2WS4 nanoparticles exhibited efficient bifunctional activity towards electrochemical hydrogen and oxygen evolution reactions. Linear sweep voltammetry (LSV) in 0.5 N H2SO4 indicated an onset potential for the HER of 462 mV and a Tafel slope of 140 mV dec(-1). LSV in 0.1 M KOH showed an onset potential for the OER of 190 mV and a Tafel slope of 117 mV dec(-1).

Summary: Drug delivery science is an important field of study that focuses on delivering therapeutic drugs to target cells while minimizing toxicity to healthy tissues. This project specifically investigates the targeted delivery of a polarity-sensitive solvatochromic model drug called ANSA to a model bio-membrane. The drug delivery is facilitated through the binding of ANSA with cyclodextrin as a drug transporter. Through detailed spectroscopic studies, it is found that the dye ANSA can be successfully delivered to the lipid-water interface region of lipid bilayers through encapsulation within cyclodextrin.
