Mechanical activation and silver supplementation as determinants of the antibacterial activity of titanium dioxide nanoparticles
(Elsevier, 2024)
Metals and metal oxides have subpar antibacterial activities compared to those of small-molecule antibiotics, yet there are hopes that with proper compositional and structural adjustments this gap might be bridged. In this ...
Microplastics in the Danube River and Its Main Tributaries - Ingestion by Freshwater Macroinvertebrates
(MDPI, 2024)
This study was carried out at the Danube River and its tributaries during the Joint Danube
Survey 4 (JDS4) expedition. Three freshwater benthic species were used to estimate the quantity
of microplastics (MPs): Corbicula ...
A Novel Two-Step Electrochemical Deposition Method for Sn-Pd Electrocatalyst Synthesis for a Potential Application in Direct Ethanol Fuel Cells
(MDPI, 2023)
Sn-Pd electrocatalysts with a constant atomic ratio of 60 at.% Sn‒40 at.% Pd suitable for
potential application in direct ethanol fuel cells were synthesized using a novel two-step electrodeposition method. First, Sn was ...
Multiferroic Heterostructure BaTiO3/ε-Fe2O3 Composite Obtained by in situ Reaction
(Belgrade : International Institute for the Science of Sintering, 2021)
Solid-state reaction between BaTiO3 and Fe2O3 was used to produce a multiferroic heterostructure composite. Commercial BaTiO3 and Fe(NO3)3•9H2O were suspended in ethanol for 30 minutes in an ultrasound bath. The prepared ...
Advances in Understanding Metal Electrolysis Process
(Switzerland : Multidisciplinary Digital Publishing Institute (MDPI), 2023)
Advancements in technologies related to the electrorefining and electrodeposition
of metals—as important manufacturing process steps—continue to receive significant
attention. Specifically, novel ideas that focus on the ...
Deterioration Characterization during Thermal Shock Testing
(International Institute for the Science of Sintering (IISS), 2023)
Thermal shock stability plays a great role in the selection of optimal refractory material. Different methods of characterization were developed for this purpose, including the implementation of nondestructive testing. ...
Understanding the Effect of Synthesis and Sintering Temperature on the Functional Properties of Barium Titanate/ Cobalt Ferrite Composites
(Association for ETRAN Society, 2023)
To investigate the effect of synthesis procedure and sintering temperature on the functional properties of perovskite/spinel ceramics, BaTiO3/CoFe2O4 composites were prepared by thermal decomposition, coprecipitation, and ...
Improved Oxygen Reduction on GC-Supported Large-Sized Pt Nanoparticles by the Addition of Pd
(Švajcarska : MDPI, 2022)
PdPt bimetallic nanoparticles on carbon-based supports functioning as advanced electrode materials have attracted attention due to their low content of noble metals and high catalytic activity for fuel cell reactions. ...
Bio-Inspired Nanomembranes as Building Blocks for Nanophotonics, Plasmonics and Metamaterials
(MDPI AG, 2022)
Nanomembranes are the most widespread building block of life, as they encompass cell and organelle walls. Their synthetic counterparts can be described as freestanding or free-floating structures thinner than 100 nm, down ...
Investigation of Nonlinear Piezoelectric Energy Harvester for Low-Frequency and Wideband Applications
(MDPI AG, 2022)
This paper proposes a monostable nonlinear Piezoelectric Energy Harvester (PEH). The harvester is based on an unconventional exsect-tapered fixed-guided spring design, which introduces nonlinearity into the system due to ...
