Recycled Wastewater Usage: A Comprehensive Review for Sustainability of Water Resources

Received: 29 August 2022;  Published: 25 November 2022;  doi: 10.21926/rpm.2204026

Abstract

Water recycling is a potential tool for reducing the dependency on traditional water sources, which would eventually reduce the likelihood of volumetric restrictions and their impacts on the water sector. Therefore, exploration, development, and use of alternative water sources are required for sustainable development. Scientific studies on the efficient and economical use of nontraditional water sources developed using the recycling process have attracted the attention of agriculturists, planne [...]

Biocompatibility and Surface Integrity of Zirconia Ceramics Treated by Laser-plasma Driven Shock-waves

Received: 10 April 2022;  Published: 22 November 2022;  doi: 10.21926/rpm.2204025

Abstract

This is a multi-disciplinary paper focused on the preliminary results of deploying laser shock treatment (LST) to ZrO2 ceramics. This work has significance in several industrial sectors for components that will benefit from strengthening. These components are, namely: dental implants; cutting and drawing tools; valves, bearings, pressure vessels, heat exchangers and high-performance scissors and knives, where modification of hard, brittle materials properties s [...]

Pentachlorophenol Effect on Auxin Production by Pseudomonas fluorescens GU059580 and Its Application in Wastewater Bioremediation

Received: 29 July 2022;  Published: 18 November 2022;  doi: 10.21926/rpm.2204024

Abstract

Bioaugmentation by Pseudomonas strains is widely used for the removal of pollutants in wastewater. In this study, we aimed to determine the removal of pentachlorophenol (PCP, 800 mg·L–1) in secondary wastewater by the bioaugmentation process. We determined the effects of using three surfactants, namely sodium dodecyl sulfate (SDS), cetyl-tri-methyl-ammonium bromide (CTAB), and Tween 80 for PCP removal. We determined the effect of the role of PCP surfactant for [...]

Application of the Extrapolation Method in Battery Diagnostics for Electric Vehicles

Received: 17 August 2022;  Published: 14 November 2022;  doi: 10.21926/rpm.2204023

Abstract

In a lithium-ion battery, the crossing of its charging–discharging curves represents an unambiguous current capacity. The reproduction of a complete charging–discharging cycle defines the maximum possible charge for a current battery state. When obtaining of the curves experimentally, one should consider the duration of polarization or depolarization. It is reported that the battery capacity depends considerably on the value of the battery’s internal resistance as this value defines the location [...]

Strength Properties of Cellulosic Fibrous Mats Impregnated with Water Repellents Based on Reclaimed Polystyrene

Received: 23 August 2022;  Published: 28 October 2022;  doi: 10.21926/rpm.2204022

Abstract

Cellulosic fibrous mats were impregnated with various water-repellent formulations based on reclaimed polystyrene (5, 10, 15, and 20%), alkyd resin (5%), gum rosin (5%), and paraffin wax (0.5%). The mats were tested for their bursting strength and resistance to bending. They were also subjected to the ring crush test and short-span compression test. By increasing the concentration of total solid ingredients (5, 10, 15, 20, and 25.5%), the retention and grammage of the mats were increased, and al [...]

Elastohydrodynamic Squeeze-film Interaction in Synovial Joints with Nanofluid Lubrication

Received: 09 July 2022;  Published: 19 October 2022;  doi: 10.21926/rpm.2204021

Abstract

New lubrication events can be predicted using improved pathological non-Newtonian physiological fluids coupled to phospholipid-based bilayers in variable time-dependent magnetic fields under random non-steady conditions. In this study, we investigated nanofluid lubrication systems for synovial joints. The particles of PSPMA-g-HSNPs were used as nanoparticles. The hydrodynamic interaction between the knee bones separated by a nanofluid film was considered here [...]

Green Synthesis of Metal-Organic Biohybrid (Mob) Nanomaterials

Received: 02 August 2022;  Published: 17 October 2022;  doi: 10.21926/rpm.2204020

Abstract

Green synthesis of nanomaterials endeavors to reduce the use of high energy methods with those that may include lower temperatures and pressures, use of natural products, and bottom-up self-assembly. Here we describe the generation of metal-organic biohybrids (MOBs) with nanoscale features synthesized at physiological (37°C) and room temperature (25°C). These MOBs utilized the naturally occurring amino acid dimer cystine as the biological component, and a series of metals, including copper, silv [...]

Optical, Charge Transport, Thermal, Magnetic, Plasmonic, and Quantum Mechanical Properties of Iridium

Received: 30 July 2022;  Published: 12 October 2022;  doi: 10.21926/rpm.2204019

Abstract

Spectrophotometry has been widely used to retrieve the dielectric function of a bulk iridium sample using an extended version of the Drude–Lorentz model. The parameters of the model are optimized using a spectral-projected-gradient-method-assisted acceptance-probability-controlled simulated annealing approach. Furthermore, optimized values of Drude parameters corresponding to the optical response of electrons and holes (scattering frequency of electrons, the ratio between scattering frequencies [...]
