Estimation of absorbed doses to target and healthy tissues during cone-beam ct radiotherapy imaging of the chest
(Romanian Journal of Physics, 2021)
The aim of this study was to assess volumetric imaging dose and image quality during radiotherapy in case of Hodgkin lymphoma. The absorbed doses were measured using ionization chamber in thorax phantom. For the same setup, ...
Photocatalytic degradation of methylene blue under natural sunlight using iron titanate nanoparticles prepared by a modified sol–gel method
(Royal Society Open Science, 2020)
The aim of this work was to synthesize semiconducting oxide nanoparticles using a simple method with low production cost to be applied in natural sunlight for photocatalytic degradation of pollutants in waste water. Iron ...
Effect of Ru3+ ions on the formation, structural, magnetic and optical properties of hematite (α-Fe2O3) nanorods
(Journal of magnetism and magnetic materialsJournal of magnetism and magnetic materials, 2021)
Nanosized hematite (α-Fe2O3) is a widely investigated material due to its favourable properties (chemically stable, environmentally safe, inexpensive) and very good performance in several advanced applications. Properties ...
Boron-doped diamond electrode as efficient sensing platform for simultaneous quantification of mefenamic acid and indomethacin
(Diamond and Related Materials, 2020)
Mefenamic acid and indomethacin, medicaments belonging to the group of non-steroidal anti-inflammatory agents, were determined separately and simultaneously at anodically prepared BDDE. Differential pulse voltammetry was ...
Thermally induced phase transformation of Mn-LTA and Mn-FAU zeolite to anorthite phases
(Science of Sintering, 2021)
Data on thermally induced transformations of Mn exchanged zeolites LTA and FAU topology are presented in this paper. Thermally induced phase transformation of Mn-exchange zeolites are followed in the range from 700 to ...
Downregulation of CD73/A2AR-Mediated Adenosine Signaling as a Potential Mechanism of Neuroprotective Effects of Theta-Burst Transcranial Magnetic Stimulation in Acute Experimental Autoimmune Encephalomyelitis
(Brain SciencesBrain Sciences, 2021)
Multiple sclerosis (MS) is a chronic neurodegenerative disease caused by autoimmune-mediated inflammation in the central nervous system. Purinergic signaling is critically involved in MS-associated neuroinflammation and ...
Suppressing Platinum Electrocatalyst Degradation via a HighSurface-Area Organic Matrix Support
(ACS Omega, 2021)
Degradation of carbon-supported Pt nanocatalysts in fuel cells and electrolyzers hinders widespread commercialization of these green technologies. Transition between oxidized and reduced states of Pt during fast potential ...
Structural and magnetic properties of P25 TiO2 nanoparticles doped by Co
(Journal of Magnetism and Magnetic Materials, 2020)
The present work reports on the structural and magnetic properties of TiO2 P25 Degussa powder doped with cobalt. Dissolution of cobalt in TiO2 matrix was achieved by precipitation of tris(diethyldithiocarbamato) cobalt(III) ...
Influence of secondary phases in A356 MMCs on their mechanical properties at macro- and nanoscale
(Journal of the Brazilian Society of Mechanical Sciences and Engineering, 2020)
Metal matrix composites are very inhomogeneous materials, and their properties depend on various parameters (production process, constituents, their interfaces, etc.). The influence of SiC microparticles (40 mu m) reinforcement ...
Effect of Hyperbaric Oxygen Therapy on Fatty Acid Composition and Insulin-like Growth Factor Binding Protein 1 in Adult Type 1 Diabetes Mellitus Patients: A Pilot Study
(Canadian Journal of Diabetes, 2020)
Objective: Metabolic changes in insulin-dependent diabetes mellitus (IDDM) impair vasodilation, and this leads to tissue hypoxia and microvascular pathology. Hyperbaric oxygen therapy (HBOT) can significantly improve the ...
