Influence of Gd3+ doping on the NaYF4 :YB3+,ER3+ structural and up-conversion properties
(Budapest : [s. n.], 2019)
application as lasers, displays, photo-thermal agents and biomarkers. Due to efficient two-phonon excitation and the large anti-Stocks shift UCNPs are able to emit visible or UV photons under excitation by near-infrared ...
Electrochemical oxidation of maricite NaFePO4 in mild aqueous solutions as a way to boost its charge storage capacity
(Belgrade : Institute of Technical Sciences of SASA, 2019)
Lithium has a low abundance in the Earth's crust, which in a few years will lead to difficult lithium production, and therefore difficult production of lithium-ion batteries. Sodium-ion batteries, on the other hand, have ...
Synthesis temperature influence on the structure, morphology and electrochemical performance of NaxMnO2 as cathode materials for sodium-ion rechearchable batteries
(Belgrade : Institute of Technical Sciences of SASA, 2019)
The lithium-ion batteries are the most commonly used for energy storage in portable devices. Since lithium is relatively rare on earth but rapidly consumed, it is necessary to find an adequate replacement. Owing to the ...
The structure and electrochemical properties of fayalite Fe2SiO4
(Belgrade : Materials Research Society of Serbia, 2019)
Fayalite has been found various applications in many fields. Here is presented its use as anode material for lithium ion batteries. The syntheses of Fe2SiO4 and its composite with carbon are conducted through solid-state ...
Cost effective alloys based catalysts for alkaline fuel cells application
(Belgrade : Materials Research Society of Serbia, 2019)
Alkaline fuel cells (AFCs) have recently become attractive as environmental friendly future power sources. It was really important having in mind that in alkaline media less expensive non noble catalysts could be used. ...
Friction at Nanoscale
(Belgrade : Serbian Ceramic Society, 2019)
In many technical fields a contact between two surfaces is very important and often the subject of research. The numerous physical phenomena that occur at the contact between two materials indicate the complexity of the ...
Morphological, structural, and functional properties of vertically aligned carbon nanotubes deposited on porous silicon layers by ultrasonic spray pyrolysis
(Elsevier, 2020)
In this work, we reported the fabrication of hybrid structures by growing the multi-walled carbon nanotubes (MWCNT) on porous silicon (PS) as a template. Aligned multi-walled carbon nanotubes have been successfully synthesized ...
Electronic ceramics fractal microstructure analysis - Minkowski Hull and grain boundaries
(Taylor & Francis, 2019)
Consolidation parameters have influence and can be used to control structure of BaTiO3 based materials. Microstructure and dielectric properties of Yb2O3 doped BaTiO3-ceramics, sintered from 1320 °C to 1380 °C have been ...
Rare-earth (Gd 3+ ,Yb 3+ /Tm 3+ , Eu 3+ ) co-doped hydroxyapatite as magnetic, up-conversion and down-conversion materials for multimodal imaging
(Springer Nature, 2019)
Taking advantage of the flexibility of the apatite structure, nano- and micro-particles of hydroxyapatite (HAp) were doped with different combinations of rare earth ions (RE3+ = Gd, Eu, Yb, Tm) to achieve a synergy among ...
Chapter 1: Biomedical Applications of Nanostructured Polymeric Materials
(Elsevier, 2019)
Nanostructured polymeric materials have been extensively used in different areas of biomedicine. They are polymeric materials in nanometer scale or composites containing polymeric nanomaterials. In particular, improvements ...
