Radiative Heat Transfer in the Chemically Reactive Unsteady MHD Squeezed Flow of Second Order Fluid with Heat Source by Mann AB* in Crimson Publishers: Peer Reviewed Material Science Journals This study investigates the radiative heat and mass transfer effects on squeezed flow of unsteady MHD second order fluid with heat source and chemical reaction. This study is carried out between two parallel circular plates under the assumption of axisymmetric squeezed flow. Similarity transform method is used to reduce the system of partial differential equation (PDE’s) into the system of ordinary differential equations (ODE’s). Advanced Collocation Method is used to find the solutions of nonlinear ordinary differential equations for velocity profile, pressure distribution, and temperature and concentration field. Effects of pertinent physical parameters on the computational results for the radial and axial velocity, pressure distrinution, and temperature and concentration profile are presented v...

Behavior of the Chemicals in the Brain in Viewpoint of Learning Cognition by a Theoretical Simulation by Fatemeh Mollaamin* in Crimson Publishers: Peer Reviewed Material Science Journals This investigation aims to provide an account of language development in terms of the brain neurochemical transmitters such as dopamine that conducts human speech mechanism using theoretical methods. Brain neurochemical transmitters are effective in language processing, so this work aims to provide an account of language development in terms of the brain neurochemical transmitters such as dopamine that conducts human speech mechanism using theoretical methods. The neurochemical structures of dopamine, epinephrine, norepinephrine, histamine and serotonin have been simulated by Monte Carlo method (MC) which uses the increased temperature to the potential energy of the neurochemicals in the brain considering the geometry optimization of the compounds as an additional conformational level. https://crimson...

Influence of Temperature and Time of Acid Etching on the Surface Morphology of Titanium for Dental Implants by  Daniel J Fernandes*  in Crimson Publishers:  Peer Reviewed Material Science Journals The surface morphology of dental implants affects the primary stability (mechanical stability), the secondary stability (osseointegration), and the tertiary stability (long-term stability). In this work, the effects of surface etching on commercially pure titanium grade 4 (cp Ti G4) were investigated. The objective was to study the influence of temperature and time of acid etching on surface roughness and morphology. The roughness parameters were measured with 3D optical surface profilers and the surface morphology was analyzed by scanning electron microscopy. The results showed that the roughness parameters R a , R sk , R z , R ms , peak size and valley depth increased as the temperature and time of etching increased. An empirical mathematical model was developed relating the e...

Performance of Corncob Ash and Anthill Soil in Ternary Concrete Mixes by Ash Ahmed* in Crimson Publishers: Peer Reviewed Material Science Journals This work investigated the performance of ternary Corncob Ash (CCA) and Anthill Soil (AHS) in concrete mixes. CCA and AHS were replaced in concrete using equal proportions at replacements of 0%, 5%, 7.5%, 10%, 15%, 20%, 25%, and 30%. Investigations covered workability, density, compressive and tensile strengths and gain in strength over time of concrete, as these were found to be the major characteristics of Supplementary Cementitious Materials (SCMs). Results showed that the two materials could be used with an advantage over individual binary concretes in these areas. https://crimsonpublishers.com/rdms/fulltext/RDMS.000595.php For more Open access journals in Crimson Publishers please click on below link https://crimsonpublishersresearch.com/ For more article in Peer Reviewed Material Science Journals please click on below link https:/...

The Application of Phase Diagram for Interfacial Reactions in Electronic Packaging by Yee Wen Yen* in Crimson Publishers: Peer Reviewed Material Science Journals The phase diagram investigation is basically scientific study of materials science and engineering. The basic materials knowledge, such as material thermodynamics and kinetic, phase transformation, and solid state diffusion can be used to explain the intermetallic compounds (IMCs) formed at the interface. Meanwhile, the phase diagram information is one of the important tools, as well. The phenomena in the interfacial reaction should be combined with the phase equilibrium information. Therefore, we can have a clear understanding of the interfacial reaction between the atomic diffusion mechanism and the final equilibrium condition. In the electronic packaging process, lead-free solders are Sn-based alloys, and the substrate is likely to be the Ni/Cu structure. During the soldering process, both Cu and Ni are rapidly dissolved i...

The Rotating Magnetic Field for Confining and Heating Plasma by Vladimir Kuzmich Shilov* in Crimson Publishers: Peer Reviewed Material Science Journals To retain and simultaneously heat the high-temperature plasma, it is proposed to use a magnetic trap creating a closed rotating magnetic field. Such a magnetic field is created by applying magnetic fields from nine open traps placed in triads in three orthogonal planes. Each trap is connected to one of phases of a three-phase AC circuit and is set at 120 degrees to the other two traps located in this plane. https://crimsonpublishers.com/rdms/fulltext/RDMS.000592.php For more Open access journals in Crimson Publishers please click on below link https://crimsonpublishersresearch.com/ For more article in Peer Reviewed Material Science Journals please click on below link https://crimsonpublishers.com/rdms/

Film Dosage Forms Prepared with Alginate for Oral Candidiasis Treatment by Yoshifumi Murata* in Crimson Publishers: Peer Reviewed Material Science Journals A film dosage form (FD) incorporating an antifungal agent, miconazole, was prepared with sodium alginate for the treatment of Candida infections. To ensure the safety of oral administration, FD was modified with additives, such as alginate hydrolysate, to control the drug dissolution rate. A soft film with a thickness of approximately 70μm was obtained and each FD was sufficiently strong to be applied by hand. FD immediately swelled in limited dissolution medium and then disintegrated to release the incorporated drug. The drug dissolution rate was controlled by the amount of additive in the film base solution. FD prepared with sodium alginate and the hydrolysate is useful for the treatment of oral candidiasis as the dosage form can be administered into the oral cavity to act directly on the affected site.

Perspectives on Chemical Modification of Carbon Nanomaterials Assisted by Microwave Radiation by Hélio Ribeiro* in Crimson Publishers: Peer Reviewed Material Science Journals Carbon nanomaterials (CNMs) as graphene and carbon nanotubes (CNTs) have attracted attention of scientific community due to their high performance and applications. However, their potential applications as nanofillers, depends necessarily of their production which high structural quality, great compatibility with the host system. For instance, in polymeric matrices this issue involves several challenges due to their low dispersibility in water and organic solvents, thus different process of chemical modification of CNMs surfaces have been reported. In cases of functionalization with amino groups, most of them use in one of their chemical steps thionyl chloride (SOCl2) as intermediate reagent. In general, the use of SOCl2 limits the chemical process, due to of its dangerous nature and high level of toxicity. Anoth...

  CO Production of Critical Energy Materials by Corby Anderson* in Crimson Publishers: Peer Reviewed Material Science Journals This issue of material criticality has been receiving much attention recently from governments all over the world. The United States and the European Union have two different definitions of what makes a material critical.  https://crimsonpublishers.com/rdms/fulltext/RDMS.000593.php For more Open access journals in Crimson Publishers please click on below link https://crimsonpublishersresearch.com/ For more article in Peer Reviewed Material Science Journals please click on below link https://crimsonpublishers.com/rdms/
