Heat transfer to a sphere immersed in a fluidized bed of coarse particles with transition from bubbling to turbulent flow regime
(Taylor & Francis Online, 2022)
The present work concerns an experimental study on heat transfer in gas-solid fluidized bed of coarse (Geldart D) particles to a larger immersed sphere at high superficial velocities from 2 to 5.5 Umf. The heat transfer ...
Calcium-pyro-hydrochar derived from the spent mushroom substrate as a functional sorbent of Pb2+ and Cd2+ from aqueous solutions
(SAGE Publications Ltd, 2022)
A calcium-pyro-hydrochar (Ca-PHC) can be distinguished as a novel sorbent of Pb2+ and Cd2+ from an aqueous solution. It was obtained using hydrothermal treatment of the spent mushroom substrate (SMS), followed by a CaCl2·5H2O ...
Analysis of inhibitory properties of Ce-citrate as a green corrosion inhibitor of low alloy steel in neutral chloride solution
(John Wiley and Sons Inc, 2022)
The new environmentally friendly corrosion inhibitor Ce-citrate was analyzed in 0.05 M NaCl solution on the AISI 4130 steel. For comparison, corrosion inhibitor Ce-chloride is tested in the same concentration as Ce-citrate ...
Statistical methods for designing a Geiger–Muller counter suitable for an early warning system
(Elsevier B.V., 2022)
The paper discusses statistical methods that can be applied when constructing the Geiger–Muller counters to obtain the same response to radiation, regardless of their dimensions. This issue is relevant for the improvement ...
Multispectral electromagnetic shielding and mechanical properties of carbon fabrics reinforced by silver deposition
(Materials Chemistry and Physics, 2022)
Electromagnetic interference (EMI) has become a widespread modern environmental pollutant. There is an essential need for practical and applicable materials for its attenuation. Therefore, the presented research has focused ...
Inhibitory effect of cysteine and lanthanides on AA7075-T6 in neutral NaCl solution
(John Wiley and Sons Inc, 2022)
The inhibitory effect of cysteine in the presence of selected lanthanide chlorides (LaCl3, NdCl3, and CeCl3) in a neutral 0.1 M NaCl solution was analyzed. The cysteine concentration of 0.3 mM was determined as an optimal ...
Volumetric and Transport Properties of Isoamyl Acetate Based Binary Systems-Experimental Determination and Modeling
(American Chemical Society, 2022)
Three binary mixtures consisting of isoamyl acetate and 1-butanol or isobutanol or isopentanol were experimentally investigated in terms of their density, viscosity refractive index, and ultrasonic speed of sound, in the ...
Multiblock copolymers containing poly(butylene succinate) and poly(ε-caprolactone) blocks: Effect of block ratio and length on physical properties and biodegradability
(Springer Science and Business Media B.V., 2022)
In order to obtain polymers with preserved thermal properties and tunable biodegradability multiblock copolymers comprising blocks of biodegradable polyesters poly(ε-caprolactone) (PCL) and poly(butylene succinate) (PBS) ...
Impact properties of Kolon/PVB fabrics reinforced with rice-husk silica particles
(Materials Letters, 2022)
This study presents the impact properties of the new form of hybrid thermoplastic composites. The Kolon fabrics were impregnated with the 10 wt% poly (vinyl butyral) (PVB)/ethanol solution with the addition of silica (SiO2) ...
Thermodynamic study of triacetin or ethyl levulinate and alcohol binary mixtures
(Academic Press, 2023)
The subject of presented research is the study of liquid binary mixtures consisting of ester and alcohol combination; triacetin or ethyl levulinate, as one component, and ethanol or isobutanol, as second component. ...
