Bifunctional catalytic activity of Zn1−xFexO toward the OER/ORR: seeking an optimal stoichiometry
(Royal Society of Chemistry, 2020)
Eco-friendly and rapid microwave processing of a precipitate was used to produce Fe-doped zinc oxide (Zn1−xFexO, x = 0, 0.05, 0.1, 0.15 and 0.20; ZnO:Fe) nanoparticles, which were tested as catalysts toward the oxygen ...
Ideal efficiency of resonant cavity-enhanced perovskite solar cells
(Springer Science and Business Media LLC, 2020)
Perovskite solar cells (PSCs) have attracted significant attention in recent years due to the rapid increase in device efficiency (reaching over 25% in 2019), ease of fabrication, and the potential to produce low-cost ...
The Artificial Neural Networks Applied for Microelectronics Intergranular Relations Determination
(Taylor & Francis, 2020)
This paper is based on fundamental research to develop the interface structure around the grains and to control the layers between two grains, as a prospective media for high-level electronic parameters integrations. We ...
Bamboo‐Membrane Inspired Multilevel Ultrafast Interlayer Ion Transport for Superior Volumetric Energy Storage
(Wiley, 2021)
Interlayer transport of charges and carriers of 2D nanomaterials is a critical parameter that governs the material and device performance in energy storage applications. Inspired by multilevel natural bamboo-membrane with ...
Assessment of Grain Size and Grain Refinement Efficiency by Calculation of Released Heat Attributed to Formation of Primary Aluminum Crystals During Solidification of Al7Si4Cu Alloy
(Springer Science and Business Media LLC, 2021)
Assessing heat released only related to the formation of primary crystals provides results with a significantly higher sensitivity than a traditional assessment of undercooling value. In this work, two similar Ti5B1 master ...
The influence of the starch coating on the magnetic properties of nanosized cobalt ferrites obtained by different synthetic methods
(Elsevier, 2021)
To investigate the magnetic behavior of starch-coated cobalt ferrites, well-established synthetic methods, i.e., coprecipitation, mechanochemical, ultrasonically assisted coprecipitation, microemulsion, and microwave-assisted ...
The low-temperature sonochemical synthesis of up-converting β NaYF4:Yb,Er mesocrystals
(Elsevier BV, 2022)
In this paper, we report the mild sonochemical synthesis of hexagonal (β) NaYF4:Yb,Er mesocrystals at low temperature of 40 °C. The nucleation and transformation of crystal structures is investigated in the course of time, ...
Characterization of silicon carbide ceramics obtained from porous carbon structure achieved by plant carbonization
(Elsevier, 2020)
The aim of this research was to obtain a carbon solid residue by the carbonization process of biomass in an inert atmosphere which, through physical activation and chemical treatment (using TEOS - tetraethyl orthosilicate) ...
Changes in long-term properties and natural cycles of the Danube river level and flow induced by damming
(Elsevier BV, 2021)
In this paper we assessed changes in scaling properties of the river Danube level and flow data, associated with building of Djerdap/Iron Gates hydrological power plants positioned on the border of Romania and Serbia. We ...
Brownian fractal nature coronavirus motion
(World Scientific Pub Co Pte Ltd, 2021)
The goal of our research is to establish the direction of coronavirus chaotic motion to control corona dynamic by fractal nature analysis. These microorganisms attaching the different cells and organs in the human body ...
