“…Additionally, the presence of a peak at 522.87 cm -1 confirms the Au-O metal binding to oxygen [14]. This observation further solidifies the notion that hydroxyl groups actively participate in the creation of a protective layer surrounding the AuNPs, thus guaranteeing their long-term stability [15].…”

Gold nanoparticles (AuNPs) have garnered significant interest in the field of biomaterials and biomedical engineering due to their wide-ranging applications, excellent biocompatibility, low toxicity, and customizable stability. This study focuses on synthesizing AuNPs through an environmentally friendly approach, specifically by utilizing the aqueous leaf extract of Allium tuberosum as both a reducing and capping agent. The synthesized AuNPs were characterized using UV-Vis Spectroscopy, revealing an absorption peak at 548 nm within the surface plasmon resonance (SPR) of AuNPs. Morphological analysis conducted via SEM showed a mixture of rod-shaped and spherical-shaped AuNPs, with dimensions of 41.0 nm (width) and 181.6 nm (length) confirmed through DLS measurements. EDX analysis confirmed the high abundance of gold in the synthesized AuNPs. Furthermore, a zeta potential value of -26.2 mV indicates that the AuNPs have decent stability. Phytochemical analyses and FT-IR results implicated that the Saponin present in the Allium tuberosum leaf extract played a crucial role in reducing metal ions and stabilizing the AuNPs. The potential of Allium tuberosum leaf extract for synthesizing diverse metal nanoparticles highlights its promise for biomaterials and biomedical engineering. The synthesized AuNPs show versatility for applications like targeted drug delivery, non-invasive imaging, and emerging biomedical uses.

“…Various conditions, including temperature (25,35,45, and 55 °C) and relative humidity (20-85%), were tested to determine the adsorption isotherm for water vapours. At 25°C and 85% relative humidity, NTPM was tested for its adsorption kinetics.…”

“…Due to the fact that at lower humidity levels, the water molecules were strongly bound to the surface functional groups of the NTPM and mostly manifested as bounded water, it was discovered that Hs values were comparatively greater at lower adsorption capacities. Although the partial pressure of water molecules increased as the relative humidity increased and they started penetrating deeper into the internal structure of the adsorbent, the values of ∆Hs were relatively modest because the bulk of the water molecules were present as free molecules [25]. NTPM has ∆Hs values ranging from 47 to 54 kg/mol (Table 2).…”

The production of innovative materials with improved features applicable in many domains is a key application of nanotechnology with far-reaching implications for modern society. Nanoparticle-based polymer composites are quickly becoming one of the most promising new materials, with potential uses spanning the chemical, physical, and biological sciences as well as engineering. Application of nanoparticle-based polymer composites for indoor air quality maintenance was discussed, as were their production, hybrid functionalization, and feasible synthesis procedures (filter membrane). The batch foaming procedure has been used to create foam from the thermoplastic polymer polypropylene (PP). Foaming is a blown process, where carbon dioxide is utilised as the blowing agent. Nanoparticles of titanium oxide (nano TiO2) are also used for reinforcement. Scanning electron microscopy (SEM) was utilised to investigate the NTPMs' surface morphology, while other physio-chemical characteristics were investigated by means of various analytical methods, including Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), and thermo-gravimetric analysis (TGA). The adsorption isotherm and kinetics of water vapours were analysed to get insight into the water vapour adsorption characteristics of the NTPMs. The kinetics of adsorption pointed to a combination of intraparticle diffusion and liquid field driving processes for the transport of water vapours. Because of their high dehumidification effectiveness, synthetic NTPMs have the potential to replace many of the currently used traditional solid desiccant materials
