“…The two investigations add to the developing comprehension of fitting nanomaterial properties for explicit applications. Pineda-Vásquez et al [9] showed the feasible combination of metal, metal oxide, and MOF nanoparticles from squander-printed circuit sheets. This study lines up with the eco-accommodating subject, displaying the capability of changing electronic waste into high-esteem nanomaterials.…”

This exploration explores eco-accommodating methodologies in the union of nanomaterials for reasonable medical services applications. Utilizing plant-intervened and microbial union techniques, biogenic platinum nanoparticles, zinc oxide nanorods, and iron oxide octahedral nanoparticles have been effectively manufactured. X-ray Diffraction (XRD) investigation affirmed the translucent designs, with trademark tops at 38.2°, 34.5°, and 30.1°, relating to (111), (101), and (220) gem planes, individually. Transmission Electron Microscopy (TEM) uncovered distinct morphologies, with normal sizes of 15 ± 2 nm for gold nanoparticles, 25 ±3 nm for zinc oxide nanoparticles, and 20 ± 1 nm for iron oxide nanoparticles. Fourier Change Infrared Spectroscopy (FTIR) demonstrated surface alterations, improving practical gatherings, including Gracious, C=O, and COOH. Measurable improvement through Plan of Experiments (DoE) and Reaction Surface System (RSM) yielded ideal amalgamation conditions, guaranteeing upgraded properties. Organic assessments exhibited the biocompatibility of the nanomaterials, with cytotoxicity tests uncovering cell viabilities of 95%, 85%, and 92% for gold, zinc oxide, and iron oxide nanoparticles, individually. Antibacterial action appraisals exhibited hindrance zones of 18 ± 2 mm, 15 ± 1 mm, and 22 ± 3 mm for silver, copper oxide, and titanium dioxide nanoparticles, individually. Natural effect appraisals uncovered low carbon impressions of 12.5 kg CO2, 8.2 kg CO2, and 10.1 kg CO2 for gold, zinc oxide, and iron oxide nanoparticles, individually. The orchestrated nanomaterials exhibit huge potential for manageable medical care applications, consolidating upgraded properties with negligible natural effects.

“…A higher amount of dispersion (1:1 and 1:1.5) reduces the stability, lowering the latent heat capacity. Kumar et al [30] observed that latent heat reduces in functionalised MWCNT/salt hydrate with SDBS surfactant. The addition of SDBS surfactant reduces the latent heat up to 16% due to the escalating temperature.…”

Advance research in phase change materials (PCMs) has been explored as a novel thermal energy storage (TES) material. The nano-filler of high-conductive material is very promising in improving the material’s thermal properties. Because of the high surface energy of nano-filler, it coagulates quickly and is difficult to disperse in PCMs. Surfactant has been explored by researchers to prevent particle cluster agglomeration and to stabilise particle suspensions. The two-step method has been used widely in synthesising Nano enhanced PCMs (NePCMs) with surfactants. Homogeneous and uniform surfactant dispersion was added not more than 1:1 to the nano-filler. Surfactant shows promising improvement in stabilising the nano-filler in PCMs. Moreover, it improves the NePCMs’ thermal conductivity (TC). However, the latent heat value drops as the nano-filler and surfactant concentrations increase.

“…Due to this, PCMs are a less preferable material for storing solar thermal energy. Researchers [6], suggested that doping of high conductive nanomaterials such as metals, fins, carbon nanotubes (CNTs), and metal oxides into the PCM increases the thermal conductivity [7]- [8]. Dispersing higher conductive nanoparticles (NPs) into the PCM increases the thermal conductivity and alters other thermal performance.…”

Thermal energy storage (TES) is a technique that is considered a very desirable technology with a high potential to overcome the gap between demand and supply. Phase change materials (PCMs) are considered to be a highly favourable thermal energy storage materials. Besides that, PCM has certain drawbacks, such as lower thermal conductivity and higher light transmission; owing to this, the heat transfer rate and energy storage density are less. The performance of the PCMs can be improved by adding highly conductive nanoparticles. In this study, various weight percentages (0.1% - 5.0%) of Copper (II) oxide nanoparticles are dispersed with salt hydrate phase change materials with melting temperature 50 °C and investigated the thermal and chemical properties using Thermogravimetric analyzer, thermal conductivity analyzer, and Fourier transform infrared spectrum. Results shows that the prepared nanocomposites have chemically and thermally stable up to 467 °C. The thermal conductivity was increased by 62.64%, at 3.0 wt% Copper (II) oxide with salt hydrate PCM. The developed nanocomposites have better thermophysical properties than pure salt hydrate, which may be applied for TES applications like solar water heating, photovoltaic thermal systems, and electronic cooling systems.
