Item Nanostructured Composites of Transition Metal Doped Cadmium Chalcogenides with g-C3N4 and their Potential Applications(UMT.lahore, 2023-01-11) Malik Imran AfzalAdvances in modern technologies have drastically changed the globe today but at the expense of severe environmental deteriorations. Emission of greenhouse and toxic gases, industrial, agricultural and household effluents and antibacterial materials used to control the microbial infections have now become an essential but damaging part of our environment. Natural methods of treating the environment like planting more trees are not able to cope with the pollution produced on huge scale in aberrant ways. It has now become crucial to invent new smart catalytic materials for environmental treatment to keep the globe livable. These catalysts materials need to be inexpensive, nontoxic, efficient and stable.Item Development of Nanocomposites to Fabricate Electrochemical Sensors and Biosensors for Phenolic Compounds(UMT.lahore, 2023-09-22) Qasar SaleemWastewater treatment and sensing are crucial activities in contemporary society, due to the increasing quantity of environmental contamination caused by human’s developed processes. With low energy requirements, cost-effectiveness, and high sensitivity, electrochemical and bioelectrochemical techniques have developed as novel options for wastewater treatment and sensing. The development of a low-cost, rapid, sensitive, portable, and selective sensing device capable of conducting multiplex detections is crucial. This research investigates the effectiveness of nanocomposites as model modifier components for enhancing electrochemical detection techniques using electrochemical sensorsItem SYNTHESIS OF SILVER NANOCOMPOSITES FOR APPLICATIONS IN TEXTILE AND POLYMERS(UMT.lahore, 2023) MUHAMMAD AMJADThe main issues confronting the researchers are the removal of hazardous organic dyes from industrial effluents and bacterial diseases. Silver nanoparticles (AgNPs) and its derivatives efficiently inhibit the growth of a variety of bacteria. In the present study, firstly AgNPs were prepared using vegetable waste extract (VWE) as a reducing agent. The fabricated nanoparticles (NPs) were characterized by UV-Visible spectroscopy, Fourier-transform infrared spectroscopy (FTIR), Scanning electron microscope (SEM), and Energy-dispersive X-ray (EDX) spectroscopy. The synthesized particles exhibited efficient antibacterial properties (by inhibiting cellular respiration, disrupting the bacterial cell membrane and inducing oxidative stress) against poultry bacteria Salmonella gallinarum and Salmonella enteritidis (growth reduction of 31 mm and 18 mm at 80 mg/mL AgNPs). The results depicted that VWE-AgNPs inhibited the growth of tested bacterial strains and it had the potential to act as a green photocatalyst for the degradation of 87.7% of methylene blue (MB) and 90.76% of methyl orange (MO) nearly at 3.25 h and 1 h sunlight exposure time, respectively. In VWE-AgNPs, the highest antifungal activity was determined to be 36.5 mm and 31.8 mm against Alternata sp. and C. albicans.
