α-Tricalcium phosphate/fluorapatite-based cement – Promising dental root canal filling material
(University of Novi Sad, Faculty of Technology, 2022)
α-Tricalcium phosphate/fluorapatite (α-TCP/FAp) mixed powders were prepared in order to obtain dental root canal filling cements. Different liquids for cement pastes have been investigated and the most suitable one for ...
Electrospun polyacrylonitrile fibers incorporated with microporous carbon for improved airborne PM2.5 filtration
(Elsevier Ltd, 2022)
Particulate matter 2.5 (PM2.5) pollutant particles have been identified as significant participants in air pollution, thus, special attention is paid to air filtration as a method of their efficient removal. A novel and ...
Thermal and dielectric properties of low-density polyethylene/NaA zeolite composites
(Polymer International, 2022)
The effect of the weight fraction of NaA zeolite on thermal properties (specific heat capacity, thermal diffusivity, thermal conductivity) and dielectric properties (electrical conductivity, real and imaginary electric ...
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 ...
Blocking the 2,3-butanediol synthesis pathway of Klebsiella pneumoniae resulted in l-valine production
(Springer Science and Business Media B.V., 2022)
Klebsiella pneumoniae is a 2,3-butanediol producing bacterium. Nevertheless, a design and construction of l-valine production strain was studied in this paper. The first step of 2,3-butanediol synthesis and branched-chain ...
Studies of Clinoptilolite-Rich Zeolitic Tuffs from Different Regions and Their Activity in Photodegradation of Methylene Blue
(MDPI, 2022)
The present study focuses on clinoptilolite (CLI)-rich natural zeolitic tuffs and their photocatalytic activity in the degradation of cationic organic dyes. CLI from different regions was tested in the photocatalytic ...
Recovery of Rare-Earth Elements from Printed Circuit Boards by Vacuum Pyrolysis and Multiple Electrostatic Separation
(MDPI, 2022)
The influence of the multi-stage electrostatic separation (ESS) of mechanically treated and magnetically separated waste electronic material and the pyrolysis of the selected ESS fraction on the distribution of metal ...
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 ...
TiO2 nanotubes film/FTO glass interface: Thermal treatment effects
(ETRAN, 2022)
Pure Ti films deposited by radio-frequency magnetron sputtering on FTO glass were anodized to fabricate TiO2 nanotubes (NTs) arrays. The TiO2 NTs/FTO samples were sintered at 450, 550 and 630°C, in ambient air. The thermal ...
