Abstract

Tryptophan capped Silver nanoparticles (AgNPs) were synthesized through a sonochemical method, utilizing tryptophan as a biocompatible and non-toxic capping agent. Based on UV–visible spectra, the optical band gap of the nanoparticles was found to be roughly 3.01 eV. The TEM and XRD measurements of the particle sizes showed a range of 10–22 nm. Under sun irradiation, these nanoparticles showed notable photocatalytic activity, destroying Methylene Blue (MB) dye by more than 79.4 %. With a pseudo-first-order apparent rate constant of 1.5×10−2min-1, the degradation kinetics were observed. The photocatalysis of MB dye was investigated using liquid chromatography in conjunction with electrospray ionization time-of-flight mass spectrometry (LC-ESI-TOF-MS) to determine the products generated and to clarify the degradation processes. Additionally, the antibacterial, anticancer potential showed thate the nanoparticles exhibited good antibacterial and notable anticancer properties. Furthermore, the antidiabetic activity was investigated through α-glucosidase inhibition, demonstrating a significant inhibition rate of 53.98 %. Antioxidant capabilities were also tested using ABTS and DPPH assays, revealing antioxidant activities of 73.9 % and 52.04 %, respectively. Overall, the synthesized tryptophan-capped AgNPs show promising applications in environmental remediation, as well as potential therapeutic uses.

Abstract

Friction Stir Welding (FSW) is one of the best choices of joining light weight metal structures involving lap joints as conventional welding methods find difficult in getting sound weld joints. Aluminium alloys are lightweight materials relatively used in space frame structures, ship buildings and panels of automotive vehicles. Main objective of this research is to investigate Al–SiC FSW lap joints and to examine the suitable pre-fill nanoparticles in the configured grooves to augment the weld strength. Three different volume additions of SiC nanoparticles and tool rotational speed were considered to fabricate lap joints for the investigations. Tool rotational speed and volume of SiC reinforcement have a significant impact on the dissemination of SiC in the weldment and weld quality. The spread of SiC nanoparticles in the weld area strongly affects the weld microstructure and mechanical characteristics. Nano SiC filled lap joint has shown a significant improvement in mechanical properties as compared to a joint without nanoparticles. The best lap joint is achieved with 20 vol% of SiC and 1500 rpm of rotational speed. The investigations imply that the tensile strength is decreased for joints with 26 vol% of SiC, due to clustering of reinforcement particles. The supplement of SiC nanoparticles restricts the growth of grains and refines the stir zone (SZ) microstructure and hence this method of weld process is recommended for lap weld joints in metal structures.
