A novel type of flexible [Fe3O4/PANI/PMMA]@{[Eu(BA)3phen + Tb(BA)3phen]/PMMA} (PMMA = polymethyl methacrylate, BA = benzoic acid, phen = phenanthroline, PANI = polyaniline) belt-shaped coaxial microcable possessing electrical conductivity, magnetism and color-tunable photoluminescence has been successfully fabricated by electrospinning technology using a specially designed coaxial spinneret. Ev...

Polymethyl methacrylate (PMMA) is one of the most popular synthetic polymers in aircraft windshields as an alternative to glass, due to its lightweight, high transparency and impact-resistant characteristics. The erosion behavior of PMMA is critical when used as an alternative to glass in an aircraft windshield. This paper presents experimental data on the effects of particle size, velocity and...

Polymethyl methacrylate (PMMA)-augmented cannulated pedicle-screw fixation has been routinely performed for the surgical treatment of lumbar degenerative diseases. Despite its satisfactory clinical outcomes and prevalence, problems and complications associated with high-strength, stiff, and nondegradable PMMA have largely hindered the long-term efficacy and safety of pedicle-screw fixation in o...

Introduction: Several attempts to invent implantable devices have done, and it is also necessary to develop biocompatible packaging materials for implantable devices. Thus, we evaluated the biocompatibility of polydimethylsiloxane (PDMS) and polymethyl methacrylate (PMMA) by analyzing of the changes of macrophage, macrophage migratory inhibitory factor (MIF) and inflammatory cytokines of the bl...

Polymethyl methacrylate (PMMA) resin is commonly used for the fabrication of a denture base heat curing polymerization. The objective this work to investigate effects using two types nanotube technology: Halloysite nanotubes (HNTs) and Multi-walled carbon (MWCNTs), on impact strength (IS), Vickers hardness (VH) PMMA base. composites were fabricated by incorporating powder, 0.5wt% benzoyl peroxi...

Abstract Background Changing of different denture base materials colours could have a detrimental impact on patients' satisfaction and make them seek more frequent adjustments to their prosthesis; hence this study was conducted investigate the colour stability conventional polymer (PMMA) polyamides. Methods Specimens PMMA thermoplastic polyamides were constructed according manufacturer instruct...

This study proposes a novel anti-icing model in which silicone rubber with low thermal conductivity is coated at different positions on material surface to change the continuity of surface. During test, surfaces aluminum alloy and polymethyl methacrylate (PMMA) are discontinuously rubber. Repeated experiments conducted verify effect proposed model. Results showed that compared conventional ice ...

Background: The purpose of this project was to derive the brachytherapy dosimetric functions described by American Association of Physicists in Medicine (AAPM) TG-43 U1 based on high dose rate 192I sources. Materials and Methods: The method utilized included both simulation of the designed Polymethyl methacrylate (PMMA) phantom using the Monte Carlo of MCNP4C and benchmarking of the simulation ...

Owing to the recent developments in polymer’s properties and application, demands for designing different structure of polymers are greater than ever. Crosslinked (CPs) a type porous materials that have variety potential applications. Because simple methods modification polymethyl methacrylate (PMMA), crosslinked PMMA considers most commonly polymeric adsorbents. A new melamine-based (C-PMMA/Me...

Abstract Strong light–matter coupling is of much interest for both fundamental research and technological applications. The recently studied bound state in the continuum (BIC) phenomenon photonics with controlled radiation loss rate significantly facilitates realization strong effect. In this work, we report experimental observation room temperature between quasi-BIC resonances supported by a z...
