“…Thus the green synthesis of nanoparticles has developed as an alternative to conventional physical and chemical methods and has the potential to mitigate some of their damaging impacts (Ahmad et al, 2022). Green synthesis is a fascinating method for producing nanoparticles since it is straightforward, cost-effective, and eco-friendly (Aravind et al, 2021).…”

The conventional chemical methods of nanoparticles synthesis have been effectively replaced by nanoparticle synthesis mediated by plants. The current study describes the environmental friendly synthesis of chromium oxide nanoparticles (Cr2O3 NPs) using Erythrophleum guineense plant extract. The synthesis of Cr2O3 NPs was validated by UV/VIS spectroscopy, Energy Dispersive X-Ray (EDX), Scanning Electron Microscopy (SEM), and X-ray diffraction (XRD) studies. The appearance of the Sharpe peak at 460 nm in the UV/Vis spectrum and the colour change caused by surface plasma resonance confirmed the formation of Cr2O3 NPs. The EDX spectrum of Cr2O3 nanoparticles revealed the presence of carbon, oxygen, and chromium, while SEM analysis revealed an irregular round morphology (with a size below 400 nm). In addition, XRD studies suggested their crystalline nature by the characteristic peaks at 34° and 36° and 42° (2Ɵ), respectively. The green synthesized Cr2O3 NPs showed promise as in-vitro cholinesterase inhibitor at tested concentrations (62.5–1,000 μg/ml), with IC50 values of 120 and 100 μg/ml against Acetylcholinesterase (AChE) and Butyrylcholinesterase (BChE), respectively. The results suggested that the green synthesized Cr2O3 NPs could be used in the future to stop enzyme from working and for other biological activities.

Nanocomposite polymers have become a major topic of research in nanotechnology. Nanoclays nanocomposite technology be able to improve the mechanical, thermal, and barrier performance properties with a minimum addition of <10 wt%. Deficiency of acrylonitrile butadiene styrene (ABS) component materials is flammability, so a method needed to increase ABS thermal which is through the synthesis of ABS nanocomposite by mixing graphene, nitrile butadiene rubber (NBR) and montmorillonite nanofil 15 (N15) in ABS mixture. Core tray has low heat resistance, easily damaged and understands composite processes that can improve the thermal properties of the materials used. This program focuses on helping to improve industri knowledge in solving the problem of processing raw materials used to produce core trays. Nanoparticle can provide industri with an understanding of the application of nanoparticles to ABS materials. Data obtained that get an increase in the knowledge, skills and income of partners. The conclution is necessary to monitor the application of nanocomposites by mixing the raw materials for making nanoparticles with graphene, NBR and N15 in a mixture of ABS, conducting increased research in plastic materials to improve quality and impact on competitive prices, establishing partnerships to product improvement with conducting research and product testing.

“…Other reports have only presented the influence of much fewer factors individually, with one response variable during bacterial-mediated AuNPs [ 9 , 18 , 22 , 28 ]; see also Table S1 . Just very recently, the fractional factorial design has been employed to investigate the determining factor for green synthesis of AuNPs by employing coffee extract [ 36 ], tuber extracts [ 37 ], and upland cress [ 38 ]. However, to our knowledge, the investigation of initially active bacterial cells of two species for AuNPs synthesis in a fractional factorial design has not been reported so far.…”

Green synthesis of gold nanoparticles (AuNPs) using microorganisms has been generally studied aiming for high-yield production and morphologies appropriated for various applications, such as bioremediation, (bio)sensors, and (bio)catalysis. Numerous approaches showed the individual effect of factors influencing the synthesis of AuNPs with limited analysis of the governing factors enhancing the production and desired quality of the precipitates. This study proposes a fractional-factorial design to investigate the simultaneous influence of seven environmental factors (cell concentration, temperature, anoxic/oxic conditions, pH, gold concentration, electron donor type, and bacterial species) on the recovery yield and synthesis of targeted AuNPs. Various sizes and morphologies of the AuNPs were obtained by varying the environmental factors studied. The factors with significant effects (i.e., 0.2 mM Au and pH 5) were selected according to statistical analysis for optimal removal of 88.2 ± 3.5% of gold and with the production of valuable 50 nm AuNPs, which are known for their enhanced sensitivity. Implications of the cytochrome-C on the bacterial mechanisms and the provision of electron donors via an electrochemical system are further discussed. This study helps develop gold recovery and nanoparticle synthesis methods, focusing on the determining factor(s) for efficient, low-cost, green synthesis of valuable materials.
