Cover Story:Ceramic Matrix Composites (CMCs) are enabling materials for use in next-generation engine hot-sections. They allow for the use of higher operating temperatures that that results in reduced environmental emissions, and which along with their lower density increases engine efficiency. The full potential of these materials is not being realized at present due to the lack of suitable mechanistic analytical models that can make use the limited test data that are usually available for these materials within a comprehensive design framework. Such a modeling approach is described herein and applied to analyzing and determining the operating life of a CMC vane. View this paper

Open Access Review

Quantum Semiconductors Based on Carbon Materials for Nanophotonics and Photonics Applications by Electron Shuttle and Near Field Phenomena

Received: 16 September 2023;  Published: 26 December 2023;  doi: 10.21926/rpm.2304037

Abstract

This review intended to resume key Research reports and publications that open many themes and topics related to Carbon-based semiconductors and Quantum emitters. The Design and synthesis of highly pure materials such as Graphene, Carbon Nanotubes, fullerenes, and other Carbon-based allotropes were shown. They presented their most important and promising properties concerning new studies and developments in photonics. Carbon-based Quantum dots, semiconductors, and higher sized Nanoplatforms allo [...]

Stress Analysis and Life Prediction of a Ceramic Matrix Composite Vane Using a Micromechanics-Based Approach

Received: 06 September 2023;  Published: 01 December 2023;  doi: 10.21926/rpm.2304035

Abstract

The results of stress analysis of a ceramic matrix composite (CMC) vane using a physics-based model developed for two-dimensional woven CMCs are presented. The model considers the inherent defects and micromechanical damage in woven CMCs along with time-dependent deformation of the constituents. Predictions include damage state under general load conditions and the global deformation response of the vane. Strain-gage data from burst tests are compared to stra [...]

Open Access Short Review

Versatile Surface Chemistry of Carbon-Based Nanoplatforms by Covalent Bonding, Non-Covalent Linking, Crosslinking, and Self-Assembling

Received: 28 July 2023;  Published: 15 November 2023;  doi: 10.21926/rpm.2304034

Abstract

This mini-review discussed the best-known chemical and synthetic methodologies used in the last years to modify carbon allotropes, with an interest in nanotechnology. In this perspective, chemistry with optoelectronics applications and recent trends within bio-applications focusing mainly on graphene and its derivatives were considered. So, the mini-review intended to focus on methodologies to add functional groups with varied reactivities, polymer chemistry, and nanoscale control. T [...]

Mesoscale Modeling of Extrusion and Solidification During Material Extrusion Additive Manufacturing

Received: 22 August 2023;  Published: 25 October 2023;  doi: 10.21926/rpm.2304033

Abstract

In this work, we apply a multiphysics approach to fused deposition modeling to simulate extrusion and solidification. Restricting the work to a single line scan, we focus on the application of polylactic acid. In addition to heat, momentum and mass transfer, the solid/liquid/vapor interface is simulated using a front-tracking, level-set method. The results focus on the evolving temperature, viscosity, and volume fraction and are cast within a set of parametric studies, to include the [...]
