Calculation of the Forces Applied to a Superconductor in Levitation in an Inhomogeneous Magnetic Field

Received: 07 July 2022;  Published: 14 September 2022;  doi: 10.21926/rpm.2203018

Abstract

Stable levitation of systems consisting of a magnetic source and a superconductor is actively investigated due to the promising applications of this technology. While huge efforts have been made for modeling these setups with numerical simulations, analytical models, in spite of their us [...]

Indoor Built Environments Attended by Primary School Children and Its Microbiology: A Cross-Project Study

Received: 10 March 2022;  Published: 24 August 2022;  doi: 10.21926/rpm.2203015

Abstract

Exposure to indoor pollutants may exert a significant effect on children health as they spend most of their time in enclosed environments. This research compared the association of biological concentrations with indoor characteristics and building materials in places where children spend significant [...]

A Case Study on the Impact of Transportation of Mass Timber Products on the Cradle-to-Gate LCA Results for an Institutional Building

Received: 21 April 2022;  Published: 05 August 2022;  doi: 10.21926/rpm.2203014

Abstract

Mass timber products (MTPs) are being adopted in new building constructions and remodels in the last three decades, credited to their renewable and low carbon footprint characteristics. However, there are no mass timber manufacturers currently existing in Atlantic Canada. Extended distances of trans [...]

Effects of Chemical Stabilisation of Eggshells-Lime and Fly-Ash-Cement on the Structural Strength of Subgrade Soil in Rural Roads

Received: 15 May 2022;  Published: 04 August 2022;  doi: 10.21926/rpm.2203013

Abstract

This study examines the chemical compositions of eggshell powder (ESP) and lime as the soil stabilisers and compared with the compositions of cement and fly-ash to understand the optimal distribution of chemical stabilisers maximising the bearing capacity and structural integrity of subgrade soil. T [...]

Solubility of Dental Ceramics in Electric Fields

Received: 21 April 2022;  Published: 15 June 2022;  doi: 10.21926/rpm.2202012

Abstract

Combining dental ceramics with other prosthetic metallic restorations might release metal ions, thus affecting the oral tissues of the patients. In this study, we evaluated the electrochemical solubility of various dental ceramics in a galvanic experimental setup in vitro. Smooth and rough feldspath [...]

Modifications of Glass Ionomer Cements Using Nanotechnology: Recent Advances

Received: 01 May 2022;  Published: 01 June 2022;  doi: 10.21926/rpm.2202011

Abstract

Glass ionomer cements (GICs) are dental materials that were invented by Wilson & Kent in 1972. They can chemically bond to enamel and dentin and can exhibit anti-cariogenic activity that allows the release and uptake of fluoride ions. They also possess the ability to render color. The setting re [...]

Role of Point of Zero Charge in the Adsorption of Cationic Textile Dye on Standard Biochars from Aqueous Solutions: Selection Criteria and Performance Assessment

Received: 19 April 2022;  Published: 19 May 2022;  doi: 10.21926/rpm.2202010

Abstract

The point of zero charge (PZC) is an inherent electrokinetic property of biochars (BC). It influences the adsorption process under certain pH conditions. Herein, we report the method of determination of the PZC values of ten standard BCs. We used the salt addition method to select the BCs with suita [...]

4D Printed Shape Memory Polymers: Morphology and Fabrication of a Functional Antenna

Received: 17 February 2022;  Published: 29 April 2022;  doi: 10.21926/rpm.2202009

Abstract

Shape memory polymers (SMPs) are smart materials that can respond to certain thermal, chemical or electrical stimuli by inducing a structural conformation change into a temporary shape. In this work, a 3D printing process based on a Vat Photo-polymerization of a shape memory polymer (SMP) was invest [...]
