Evolution of the microstructure of disperse ZnO powders obtained by the freeze-drying method
(Lausanne : Elsevier Science, 2004)
Freeze-drying, as a cryochemical powder processing method is applied in the synthesis of ZnO submicrometer to narrosized powders. The process involves rapid freezing of the sprayed precursor solution, drying under vacuum ...
Gadolinium-labelled cell scaffolds to follow-up cell transplantation by magnetic resonance imaging
(Basel : MDPI, 2019)
Cell scaffolds are often used in cell transplantation as they provide a solid structural support to implanted cells and can be bioengineered to mimic the native extracellular matrix. Gadolinium fluoride nanoparticles ...
Analysis of the initial-stage sintering of mechanically activated SrTiO3
(ETRAN, 2019)
The initial-stage of sintering plays a significant role in determining the final microstructure that defines the main characteristics of electroceramics materials such as functional properties. In this article non-isothermal ...
Valorization of walnut shell ash as a catalyst for biodiesel production
(Elsevier, 2020)
The catalytic activity of the walnut shell ash was investigated in the biodiesel production by the sunflower oil methanolysis. The catalyst was characterized by the TG-DTA, XRD, Hg porosimetry, N2 physisorption, SEM, and ...
Deep insight into the photoluminescent monocrystalline particles: Heat-treatment, structure, mechanisms and mechanics
(Elsevier, 2019)
The red light emitting down-converting Ag@Y2O3:Eu3+ phosphor particles were synthesized by one-step ultrasonic spray pyrolysis and exposed further to the heat treatment at 1000°C (12h). A detailed investigation on structural ...
Fractal Nature of Advanced Ni-Based Superalloys Solidified on Board the International Space Station
(Basel : MDPI AG, 2021)
Materials science is highly significant in space program investigation, energy production and others. Therefore, designing, improving and predicting advanced material properties is a crucial necessity. The high temperature ...
Flexibility index and decreasing the costs in energy systems with high share of renewable energy
(Elsevier BV, 2021)
Recent European Green Deal includes decision to become carbon neutral and even carbon negative region in order to tackle the climate crisis. Main technical challenge and a key factor in techno-economic analysis of the ...
Graph theory applied to microelectronics intergranular relations
(Taylor & Francis Group, 2021)
The focus of this study is on the control of layers between grains by applying graph theory. We performed modification of BaTiO3 nanoparticles with Y2O3. The results of capacitance change on submicron level are the part ...
Spray drying of Gentiana asclepiadea L. root extract: Successful encapsulation into powders with preserved stability of bioactive compounds
(Elsevier BV, 2021)
Willow gentian as a source of bitter compounds is traditionally used for digestive disorders. Gentiana root extract was spray dried using five different carriers (maltodextrin, whey protein, pectin, starch, gelatine) at ...
Uticaj stabilizatora na fizičkohemijska svojstva nanočestica selena dobijenih hemijskom redukcijom
(Beograd : Savez inženjera i tehničara Srbije, 2021)
Nanočestice selena (SeNPs) su specifična forma ovog elementa koja je u poslednje vreme postala predmet brojnih istraživanja, pogotovo u oblasti biomedicine. Do sada je razvijeno više metoda sinteze SeNPs, među kojima se ...
