Assessment of Mineral Gain in White Spot Lesions Using CPP-ACP and CPP-ACFP in Different Clinical Protocols: A Proof of Concept Study

Received: 28 September 2021;  Published: 26 November 2021;  doi: 10.21926/rpm.2104046

Abstract

Subsurface remineralization can be promoted by the topical application of nanoparticles of casein phosphopeptide-amorphous calcium phosphate (CPP-ACP). To assess changes in enamel white spot lesions, an in situ proof-of-concept investigation was performed using 5 subjects (all of whom we [...]

Meat Waste Valorization through Protein Hydrolysis using Different Types of Proteases

Received: 12 May 2021;  Published: 08 November 2021;  doi: 10.21926/rpm.2104045

Abstract

Five different commercial proteases (Alcalase 2.4L, Flavourzyme 1000L, Neutrase, Protamex, and PTN) were evaluated for the simultaneous recovery of protein and lipids through hydrolysis. The hydrolysis reaction was monitored using the pH-stat procedure, in which samples were collected af [...]

Reverse Mode Polymer Dispersed Liquid Crystal-based Smart Windows: A Progress Report

Received: 17 August 2021;  Published: 01 November 2021;  doi: 10.21926/rpm.2104044

Abstract

The reverse mode polymer dispersed liquid crystal (PDLC) is an emerging smart window technology. Unlike traditional PDLCs, a reverse mode PDLC can be transparent and opaque in the absence and presence of an external electric field. This report provides a brie [...]

Quantum Chemistry Estimation of Adhesion Strength of Hydroxyapatite with Titanium Substrate

Received: 12 May 2021;  Published: 27 October 2021;  doi: 10.21926/rpm.2104043

Abstract

One of the ways to improve the fusion of an implant with bone tissue is through the use of biocompatible coatings, in particular, hydroxyapatite (HAp). It is important to assess the strength of the HAp adhesion to the implant. The measure of the strength of the bond of the coating with t [...]

Efficient Debye Function Interpolation Formulae: Sample Applications to Diamond

Received: 17 June 2021;  Published: 22 November 2021;  doi: 10.21926/rpm.2104042

Abstract

The well-known classical heat capacity model developed by Debye proposed an approximate description of the temperature-dependence of heat capacities of solids in terms of a characteristic integral, the T-dependent val [...]

Durability of Alkali-Activated Materials Made with a High-Calcium, Basic Slag

Received: 09 June 2021;  Published: 13 October 2021;  doi: 10.21926/rpm.2104041

Abstract

Alkali activated (AA) materials have been investigated for decades as an alternative to Portland cement (PC) products. Most consist of a silicate waste activated with alkalis, which leads to lower green-house gas emissions and a substantial drop in the use of unrenewable material resourc [...]

Hydration and Microwave Curing Temperature Interactions of Repair Mortars

Received: 24 June 2021;  Published: 09 October 2021;  doi: 10.21926/rpm.2104040

Abstract

Microwave curing of repair patches provides an energy efficient technique for rapid concrete repair. It has serious economic potential due to time and energy saving especially for repairs in cold weather which can cause work stoppages. However, the high temperatures resulting from the combination of [...]
