Abstract

Molecular modelling and simulation were used to examine the efficacy of iron nanoparticles (Fe3O4–NPs) in removing amoxicillin (AMX) from aqueous media and determine the optimal conditions. Fe3O4–NPs were initially ascertained using scanning electron microscopy, and Fourier transform infrared spectroscopy. The molecular optimisation modelling via DFT confirmed AMX molecule has chemical potential (–3.59), and electrophilicity index (2.14). The results established that a small chemical hardness = 3.0 eV and molecular energy gap of 6.01 eV, which makes it reactive. The molecule of the antibiotics could interact and be absorbed by the lactase enzyme. The parameters: pH (3–7), time (15–80 min), Fe3O4–NPs dosage (0.1–1.0 g/L), and antibiotic concentration (10–100 mg/L) were studied. The impact of optimum variables pH3, and dosage (0.5 g/L) for adsorption of AMX molecules onto coated Fe3O4–NPs translated to 98% efficiency at 60 mg/l of AMX and 60 min. The adsorption data fitted the Langmuir (R2: 0.9245) with minimal error metrics RMSE ≤ 1.2 when compared to the Freundlich isotherm R2 (0.88) and intraparticle diffusion model R2 (0.58). The maximum adsorption capacity of AMX to Fe3O4–NPs corresponds to 6.47 mg/g with a corresponding adsorption constant of 2.8. Furthermore, AMX adsorption onto Fe3O4–NPs followed pseudo-second-order at R2 (0.9999), with an adsorption constant (k = 3.6 × 10−2g/mg.min). [ABSTRACT FROM AUTHOR]

Abstract

The advancement of nanofluids as an enhanced liquid combination with a low percentage of nanometer-sized solid particles in suspension has only been studied for a few decades. A nanofluid is a fluid with nanometer-sized particles. Nanoparticles are dispersed in a common base fluid such as water, oil, ethylene glycol etc. In this work a study of nanofluids and its fluid flow applications and theoretical physics in a variety of areas, including chemical engineering, biomedical technologies, materials used in sustainable modern architecture studies will be conducted. The characteristics of nanofluids are discussed, as well as their applications in fields such as energy, mechanics, and biomedicine. The characteristic that challenges the utilization of nanofluids in various applications is then explained, and ultimately, nanofluids are proposed for further research. At a very low volume fraction nanofluids enhance the thermal conductivity of suspended particles. Nanofluids are now being utilized efficiently in alternative energy sources to absorb sunlight and raise temperature. [ABSTRACT FROM AUTHOR]

Abstract

In recent years, many researchers have focused on the cognitive aspects and mental structures of the managers to identify the strategies. They claim that in order to become familiar with how strategies are formulated and developed, they should evaluate the mind of the strategists and somehow decode the black box. Therefore, the present study aimed to understand the managers' strategic thinking process and to investigate the similarities in their thinking processes. Semi-structured interviews were conducted based on Zaltman metaphor elicitation technique (ZMET) interviews process. Interviews were conducted with 18 managers from two dairy industry companies. The data were analyzed based on emerging approach to grounded theory. The results of this study demonstrated that the managers of a company are using a shared mental model during strategic thinking. This similarity in their thinking process can be considered to be due to their communications and collaborative work experience. In addition, comparing the common mental model in the two companies, no significant similarity was found in their thinking process. But, there are some similarities between the mental structures of the managers of the two companies. [ABSTRACT FROM AUTHOR]
