Review on Some Important Research Progresses in Biodegradable Plastics/Polymers

Received: 15 March 2024;  Published: 27 June 2024;  doi: 10.21926/rpm.2402015

Abstract

Biodegradable plastics/polymers may serve as a promising solution to the global problem of plastic waste accumulation in oceans and soil and may significantly reduce carbon emissions from the manufacturing process, since the materials used to make biodegradable polymers are carbon-based and emitted during the synthesis processes. This article systematically reviewed the existing and closely related scientific literature on materials, biomaterials, and biodegradable materials to find answers on h [...]

Development of the Stochastic Interpretation of Quantum Mechanics by E. Nelson. Derivation of the Schrödinger-Euler-Poisson Equations

Received: 10 November 2023;  Published: 26 June 2024;  doi: 10.21926/rpm.2402014

Abstract

The article aims to develop the stochastic interpretation of quantum mechanics by E. Nelson based on balancing the intra-systemic contradiction (i.e., antisymmetry) between “order” and “chaos”. For the set task, it is proposed to combine two mutually opposite system-forming principles: “the principle of least action” and “the principle of maximum entropy” into one, the “principle of averaged efficiency extremum”. In a detailed consideration of the averaged states of a chaotically wan [...]

The Effect of Rake Angle and Cutting Edge Radius on the Orthogonal Cutting Process of Ti6Al4V Alloy

Received: 23 February 2024;  Published: 18 June 2024;  doi: 10.21926/rpm.2402013

Abstract

This paper investigates the effect of rake angle, α, cutting edge radius, r, and feed rate, f, on the cutting force and cutting zone temperature during orthogonal dry cutting of Ti6Al4V. A numerical model representative of the 2D orthogonal cutting process is developed using ABAQUS/Explicit software. Johnson-Cook, (JC) constitutive material model is used to describe material plasticity. JC damage model and energy-based fracture criterion are used to describe damage initiation and evo [...]

Spin Entanglement – A Unifying Principle for Superconductors and Molecular Bonding

Received: 20 December 2023;  Published: 03 June 2024;  doi: 10.21926/rpm.2402012

Abstract

The spin-statistics theorem is generalized to include quantum entanglement. Specifically, within the context of spin entanglement, we prove that isotropically spin-correlated (ISC) states must occur in pairs. This pairing process can be composed of parallel or anti-parallel states. Consequently, the article proposes using ISC states as a unifying principle to explain better Bose-Einstein condensates, the theory of superconductivity, and molecular and atomic orbitals, all of which inv [...]

Enhancing Thermal, Viscoelastic, and Mechanical Properties of Silicone Rubber Matrix through Reinforcements for Use as a Medical Implant

Received: 14 December 2023;  Published: 03 May 2024;  doi: 10.21926/rpm.2402011

Abstract

The use of silicone rubber as an implant is limited due to its weak properties. In this study, the impact of various reinforcements, such as TiO2 or SiO2 nanoparticles, carbon, or polypropylene fiber micro reinforcements, on the mechanical, thermal, and viscoelastic properties of silicone rubber composites with RTV-4125 matrix was investigated. The composites were evaluated through several tests, including tensile, compression, FTIR, TGA, DMTA, and w [...]

Whisker Bond: From Findings to Concept in Refractories

Received: 12 January 2024;  Published: 12 April 2024;  doi: 10.21926/rpm.2402010

Abstract

Ceramic bonds are conventionally formed during the burning of refractory bricks and by using pre-fabricated blocks or monolithic lining, which is characterized as the coalescence of the particles by liquid sintering. However, the whisker bond was discovered with the outstanding performance of unburnt periclase–spinel–Al bricks while substituting magnesia–chrome bricks in the chromium-free campaign of refractory lining of RH degassers. Thanks to the p [...]

Review on the Development of Titanium Diboride Ceramics

Received: 02 January 2024;  Published: 03 April 2024;  doi: 10.21926/rpm.2402009

Abstract

Titanium diboride (TiB2) materials have garnered significant attention due to their remarkable comprehensive properties. They offer potential applications in high-temperature structural materials, cutting tools, armor, electrodes for metal smelting, and wear-resistant parts. However, due to the low self-diffusion coefficient, the TiB2 exhibits poor sinterability, excessive grain growth at elevated temperatures, and inadequate oxidation resistance, li [...]
