GC-MS/MS and LC-MS/MS analysis followed by risk ranking of mepiquat and pyrethroids in coffee
(Academic Press Inc., 05-2024)
Pesticides used in coffee cultivation may remain behind and pose a risk to humans even after various processing stages of coffee beans (washing, drying, roasting, and grinding). In addition to pesticides applied to battle ...
Comparative chemometric and quantitative structure-retention relationship analysis of anisotropic lipophilicity of 1-arylsuccinimide derivatives determined in high-performance thin-layer chromatography system with aprotic solvents
(Elsevier B.V., 2020)
Numerous structurally different amides and imides including succinimide derivatives exhibit diverse bioactive potential. The development of new compounds requires rationalization in the design in or- der to provide structural ...
Failure analysis of welded joint with multiple defects by extended Finite Element Method and Engineering Critical Analysis
(Elsevier Ltd., 06-2024)
Failure analysis of welded joint with multiple defects was performed taking into account the effect of all defects, not just a dominant one. Four cases of multiple defects in welded joint under the uniaxial tensile loading ...
Viscosity of methyl and ethyl esters: Experiments and modeling
(Elsevier B.V., 2023)
Viscosity and density have been measured for a number of ethyl esters (ethyl ethanoate, ethyl butanoate, ethyl dodecanoate and ethyl tetradecanoate) at four temperatures between 288.15 and 323.15 K at 101.3 kPa. The ...
Palladium-copper bimetallic surfaces as electrocatalysts for the ethanol oxidation in an alkaline medium
(Elsevier B.V., 2023)
Two types of Cu-modified Pd catalysts supported on high area carbon were prepared: Pd nanoparticles modified with a sub-monolayer of underpotentially deposited Cu (Cu@Pd/C) and Pd-Cu alloy nanoparticles (Pd-Cu/C), and ...
The chicken eggshell calcium oxide ultrasonically dispersed over lignite coal fly ash-based cancrinite zeolite support as a catalyst for biodiesel production
(Elsevier, 2021)
Lignite coal fly ash (FA) from a domestic thermal power plant was converted into a pure cancrinite zeolitic material (ZMFA) using a novel, custom-made, rotating autoclave reactor system by a short-term alkali activation ...
Implementation of the Chicot-Lesage Composite Hardness Model in a Determination of Absolute Hardness of Copper Coatings Obtained by the Electrodeposition Processes
(Metals, 2021)
The influence of various electrolysis parameters, such as the type of cathode, composition of the electrolyte and electrolysis time, on the morphology, structure and hardness of copper coatings has been investigated. ...
Recovery of Vanadium (V) Oxyanions by a Magnetic Macroporous Copolymer Nanocomposite Sorbent
(Metals, 2021)
An amino-functionalized magnetic macroporous copolymer of glycidyl methacrylate (GM) and ethylene glycol (E) dimethacrylate (m-poly(GME)-deta) was synthesized, fully characterized, and used to investigate the adsorption ...
Native bovine hemoglobin reduces differentiation capacity of mesenchymal stromal cells in vitro
(Elsevier, Amsterdam, 2020)
We have tested in vitro effects of hemoglobin from bovine slaughterhouse blood (BHb) on stromal cells of mesodermal origin, with an aim to explore its use as a component of cell culture media. Human peripheral blood ...
