Structural, morphological and luminescence properties of nanocrystalline up-converting Y1.89Yb0.1Er0.01O3 phosphor particles synthesized through aerosol route
(Elsevier, 2013)
Nanocrystalline up-converting Y₂ O₃Yb³⁺ Er³⁺ phosphor particles were processed in a dispersed system-aerosol, generated ultrasonically at 1.3 MHz from common nitrate precursor solution having fixed ytterbium-to-erbium ...
Development of lyophilized spherical particles of poly(epsilon-caprolactone) and examination of their morphology, cytocompatibility and influence on the formation of reactive oxygen species
(Paris : Association de pharmacie galenique industrielle, 2014)
A common limitation of using polymeric micro- and nanoparticles in long-term conservation is due to their poor physical and chemical stability. Freeze-drying is one of the most convenient methods that enable further ...
The impedance analysis of sintered MgTiO3 ceramics
(Elsevier, 2017)
In the present study the effect of preparation conditions on microstructure and electrical properties of MgTiO3 ceramics was investigated. Mixture of MgO and TiO2 powders was subjected to mechanical activation for different ...
Stochastic digital DFT processor and its application to measurement of reactive power and energy
(Elsevier, 2018)
In this paper we present the model of digital stochastic DFT processor. Compared to the classical DFT/FFT processors, the proposed model has two advantages: first, it is much simpler and cheaper to implement, and second, ...
A facile route for hydroxyapatite densification with an increased heating rate
(Elsevier, 2017)
The densification behavior of hydroxyapatite nanorods prepared by chemical precipitation method in open reactor conditions was investigated by application of different heating rates. The non-isothermal processing was ...
Aerosol route as a feasible bottom-up chemical approach for up-converting phosphor particles processing
(Elsevier, 2013)
The opportunities of the hot wall aerosol synthesis, i.e. conventional spray pyrolysis (CSP) method are demonstrated for the generation of highly spherical three-dimensional (3D) nanostructured phosphor particles with ...
Effects of low-intensity electrical stimulation and adipose derived stem cells transplantation on the time-domain analysis-based electromyographic signals in dogs with SCI
(Elsevier, 2019)
The application of low-intensity electrical stimulation (LIES) to neural tissue increases neurochemical factors responsible for regeneration as nerve growth factor. Stem cell (SC) therapy for patients with Spinal cord ...
Polyethersulfone/poly(acrylic acid) composite hydrogel membrane reservoirs for controlled delivery of cationic drug formulations
(Elsevier, 2018)
We present the innovative synthesis of polyethersulfone/poly(acrylic acid) composite hydrogel membranesperformed by combining photoirradiation with a traditional liquid phase inversion process.Fabricated membranes exhibited ...
Effects of mechanical-activation and TiO2 addition on the behavior of two-step sintered steatite ceramics
(Elsevier, 2019)
Steatite, as ceramic with composition predominantly resting on magnesium silicate, was produced from economic resources – talc, aluminosilicate clays, and either BaCO3 or feldspar as flux. Titanium dioxide was a doping ...
Properties of 3Y-TZP zirconia ceramics with graphene addition obtained by spark plasma sintering
(Elsevier, 2018)
In this study the influence of graphene addition on the microstructure, phase composition, mechanical, and electrical properties of 3Y-TZP ceramics was investigated. Blends of pure 3Y-TZP and with addition of 1 − 4 vol% ...
