In this study, we present a novel and sustainable approach for the synthesis of silver nanoparticles (AgNPs) using waste materials, dried banana pith extract (BPE) and rice water. The synthesised AgNPs exhibit a size of 43 nm and zeta potential of −24.1 mV. A maximum temperature rise of 4°C with an efficiency of 41% is achieved within a short time by the photothermal activity. The qualitative colorimetric detection of Fe3+ and its quantitative spectroscopic detection are achieved in a linear detection range of 20–80 μM and with a limit of detection of 8.5 μM. The sensing mechanism is explained in terms of cooperative binding of Fe3+ ions to BPE-AgNPs. A homogeneous, flexible and stable AgNP-rice starch gel is formed.

The prepared NiFeS underwent a thorough investigation, which included analyses of its optical, electrical, structural, morphological, elemental, and functional group properties. Cubic crystal formations with prominent peaks were visible from the structural pattern. Nanoflakes and pebbles were visible, and their elements were determined through elemental dispersive X-ray diffractometer (EDX) spectrum. The film’s crystallinity increased after incorporating carbon ions and its optical properties improved, with energy band gap values ranging from 1.50 eV to 1.15 eV as the peaks became more distinct. The materials produced could be utilised in the production of solar cells and optoelectronic devices. The electrical conductivity diminishes with increasing thickness. Carbon ion radiation increases carrier concentration, which increases electrical conductivity.Research highlightsNiFeS was irradiated using 500 keV carbon C++ ions beam irradiationNiFeS without irradiation has a bandgap of 1.50 eV, while the irradiated material had bandgaps between 1.35-1.15 eV.The film’s crystallinity was enhanced by incorporating carbon ionsNanogels and nanoflakes were seen in the micrographs of the unirradiated materials.KEYWORDS: NickelNiFeSions beamcarbonenergy bandgapirradiation Disclosure statementThe authors affirm no financial or interpersonal conflicts affected the research in this study.Data availability statementData can be given upon request.Authors’ credit statementIjabor Okeoghene Blessing, Haneef Shah, Imosobomeh L.
