Mechanochemical preparation and characterization of CaO·ZnO used as catalyst for biodiesel synthesis
(Elsevier, 2012)
In this study, the synthesis of biodiesel or fatty acid methyl esters (FAME) from sunflower oil and methanol using CaO·ZnO catalyst was investigated. Catalyst was synthesized by ball milling of Ca(OH)2 and ZnO powder mixture ...
The contribution of fractal nature to BaTiO3-ceramics microstructure analysis
(Elsevier, 2012)
The structure of BaTiO3 based materials can be controlled by using different technological parameters and different additives. In this paper, microstructure and dielectrical properties of Er2O3 doped BaTiO3-ceramics, ...
Chapter 1 - Biomedical inorganic nanoparticles: preparation, properties, and perspectives
(Elsevier, 2019)
Nanotechnology has great potential in the biomedical field. Among other nanomaterials, inorganic nanoparticles have become extremely important since they possess unique physicochemical properties influenced by their specific ...
Application of raw peach shell particles for removal of methylene blue
(Elsevier, 2015)
A possibility to apply raw, powdered peach shells (PS) as a biosorbent for water purification was studied. The PSs are locally available as a solid waste in a fruit juice factory; methylene blue (MB) was chosen as ...
Preparation and characterization of Cu and Zn modified nickel manganite NTC powders and thick film thermistors
(Elsevier, 2013)
A simple ball milling/thermal treatment procedure was applied to obtain fine thermistor powders. Three different powder compositions were analyzed–Cu0.2Ni0.5Zn1.0Mn1.3O4, Cu0.25Ni0.5Zn1.0Mn1.25O4 and Cu0.4Ni0.5Mn2.1O4. XRD ...
Integer codes correcting double asymmetric errors
(The Institution of Engineering and Technology, 2016)
In this study, the authors present a class of integer codes capable to correct single and double asymmetric errors within a codeword. The encoding/decoding procedures for these codes are extremely simple, whereas the error ...
Soft chemistry routes for synthesis of rare earth oxide nanoparticles with well defined morphological and structural characteristics
(Journal of Nanoparticle Research, 2011)
Phosphors of (Y0.75Gd0.25)2O3:Eu3+ (5 at.%) have been prepared through soft chemistry routes. Conversion of the starting nitrates mixture into oxide is performed through two approaches: (a) hydrothermal treatment (HT) at ...
Poly(DL-Lactide-co-ε-Caprolactone)/Poly(Acrylic Acid) Composite Implant for Controlled Delivery of Cationic Drugs
(Wiley, 2019)
Poly(DL-lactide-co-ε-caprolactone)/poly(acrylic acid) implantable composite reservoirs for cationic drugs are synthesized by sequentially applying photoirradiation and liquid phase inversion. The chemical composition and ...
Analytical modeling of activation procedure applied in α-alumina thermo-mechanical synthesis
(Elsevier, 2015)
The impact of the mechanical processing parameters on the alumina grain-size distribution affiliated characteristics and on the γ to α phase transformation rate was investigated. The moderation in the alumina samples ...
Fractal frontiers in microelectronic ceramic materials
(Elsevier, 2019)
The world's perennial need for energy and microelectronic miniaturization brings with it a broad set of technological and scientific challenges. Materials characterized by precise microstructural architectures based on ...
