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 ...
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 ...
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 ...
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 ...
Structural and optical characterization of titanium–carbide and polymethyl methacrylate based nanocomposite
(Springer, 2022)
The rich chemistries and unique morphologies of titanium carbide MXenes, made them strong candidates for many applications like sensors and electronic device materials. During the synthesis procedure, chemical etching, ...
Micro-kinetic model of fructo-oligosaccharide synthesis for prebiotic products
(John Wiley and Sons Inc., 2023)
A new micro-kinetic model of the enzyme-catalyzed synthesis of fructo-oligosaccharides (FOS) was developed. A commercial enzyme mixture Pectinex® Ultra SP-L derived from Aspergillus aculeatus was used. A variety of initial ...
Structural, Mechanical and Electrical Characteristics of Copper Coatings Obtained by Various Electrodeposition Processes
(Electronics, 2022)
Mechanical (hardness and adhesion) and electrical (sheet resistance) characteristics of electrolytically produced copper coatings have been investigated. Morphologies of Cu coatings produced galvanostatically at two current ...
Enhanced antimicrobial properties and bioactivity of 3D-printed titanium scaffolds by multilayer bioceramic coating for large bone defects
(IOP Publishing, 2023)
The restoration of large bone defects caused by trauma, tumor resection, or infection is a major clinical problem in orthopedics and dentistry because postoperative infections, corrosion, and limited osteointegration of ...
Antioxidant and neuroprotective activities of selected 2-pyridones: In vitro and in silico study
(Elsevier B.V., 2022)
Series of twenty-four 2-pyridone derivatives were screened and selected using the antioxidant ABTS assay
in order to find the most prominent compounds for further in vitro and in silico analyses. Seven derivatives with ...
