In this work, a study of hydroxyapatite (HAp) powders obtained using both, porcine bones and chemical precursors was carried put. the case HAp by means bones, physical processes as cooking, washing milling were developed, for removing organic material from bones; after that, submitted to thermal treatment at 800 °C, during 12 h. This procedure out without adding alkalines that are harmful environment human health. On other hand, also synthetized precipitation method widely reported, showing...
We present an adaptive algorithm for the optimal phase space sampling in Monte Carlo simulations of 3D Heisenberg spin systems. Based on a golden rule Metropolis which states that acceptance rate [Formula: see text] is ideal to efficiently sample space, adaptively modifies cone-based update method keeping close text]. have assessed efficiency through four different tests and contrasted its performance with other common methods. In systems at low high temperatures anisotropies, proved be most...
In this work, iron oxide nanoparticles produced using the laser ablation technique were studied in order to determine characteristics of these as a function energy for possible application magnetic hyperthermia. Nanoparticles obtained by varying power considering values 90, 173, 279 and 370 mJ. The morphology was determined dynamic light scattering (DLS) transmission electron microscopy (STEM) techniques, confirming that size particles nanometers. A great influence on particle also observed,...
Silver nanoparticles (AgNPs) have aroused great interest for applications as fungicides in agriculture. This study reports the synthesis of AgNPs by green chemistry using silver nitrate (AgNO3) precursor agent and a coriander leaf extract reducing surfactant. The evaluation their antifungal properties was carried out when placed contact with Fusarium solani Rhizopus stolonifer phytopathogens. AgNP characterizations were performed UV-Vis spectroscopy, X-ray diffraction (XRD), Fourier...
In this study, we research the innovative application of multi-walled carbon nanotubes (MWCNTs) as corrosion inhibitors in Portland cement embedded steel. The physicochemical properties dispersion solutions were evaluated, varying storage time, to analyze their effect on resistance. Using a energy 440 J/g and constant molarity 10 mM, stable dispersions achieved for up 3 weeks. These characterized using Raman spectroscopy, UV-Vis spectroscopy Zeta potential assess stability structural damage...
We investigated the hysteresis, pseudo-critical, and compensation behaviors of a quasi-spherical FeCo alloy nanoparticle (2 nm in diameter) using Monte Carlo simulations with thermal bath-type algorithms 3D mixed Ising model. The nanostructure was modeled body-centered cubic lattice (BCC) through following configurations: spin S=3/2 for Co Q=2 Fe. These reveal that, under influence crystal magnetic fields, exhibits phenomena, exchange bias, pseudo-critical temperatures. Knowledge this type...
The aim of this study was to prepare nanogels based on gelatin and xanthan-aldehyde for the enhancement ibuprofen transdermal delivery. Firstly, process formulating using reaction Schiff’s base optimized experimental designs. Secondly, structural characterization performed laser particle size, zetometry, FTIR (Fourier Transform Infrared Spectroscopy), XRD (X-Ray Diffraction), SEM (scanning electron microscopy), thermogravimetric analysis. Finally, evaluation pharmacological characteristics...
Abstract Two computational methods based on the Ising model were implemented for studying temporal dynamic in co-authorship networks: an interpretative real networks and another simulation via Monte Carlo. The objective of is to evaluate if describes similar way network magnetic system, so that it can be found a generalized explanation behaviours observed networks. scientific papers used building acquired from WoS core collection. variables each record took into account bibliographic...
