Production of activated carbon derived from waste hemp (Cannabis sativa) fibers and its performance in pesticide adsorption
(Elsevier, Amsterdam, 2015)
The main objective of this work was to find optimal production parameters for the preparation of activated hemp fibers (ACh) with good adsorption properties toward pesticides. In order to examine the role of manufacturing ...
Damage behavior of orthopedic titanium alloys with martensitic microstructure during sliding wear in physiological solution
(Sage Publications Ltd, London, 2019)
Wear damage behavior of new orthopedic Ti-13Nb-13Zr (mass %) alloy with martensitic microstructures developed by different thermo-mechanical treatments were examined during sliding in simulated physiological solution. The ...
Natural Macromolecules as Carriers for Essential Oils: From Extraction to Biomedical Application
(Frontiers Media Sa, Lausanne, 2020)
Essential oils (EOs) and their main constituents, the terpenes, are widely studied, mostly relating to their antioxidant ability and bioactivity, such as antimicrobial, anticancer, anti-inflammatory, and range of other ...
Use of carbon paste electrode and modified by gold nanoparticles for selected macrolide antibiotics determination as standard and in pharmaceutical preparations
(Elsevier B.V., 2020)
In this work, carbon paste electrode (CPE) and carbon paste electrode modified with gold nanoparticics (AuNPs/CPE) were employed with rapid direct anodic square wave voltammetry (SWV) for macrolide antibiotics erythromycin ...
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 ...
Optimization of forced periodic operations in milli-scale fixed bed reactor for Fischer-Tropsch synthesis
(Elsevier, Amsterdam, 2020)
One-dimensional pseudo-homogenous dynamic reactor model, incorporating detailed Fischer-Tropsch kinetics, was applied in a theoretical analysis of forced periodic operations. A milli-scale fixed-bed reactor was analyzed, ...
Pt supported on nano-tungsten carbide as a beneficial catalyst for the oxygen reduction reaction in alkaline solution
(Elsevier, 2012)
Platinum nanocatalyst at nano-tungsten carbide was synthesized, characterized and tested for oxygen reduction reaction (ORR) in 0.1 mol dm−3 NaOH, at 25 °C. Tungsten-carbide islands on nano-tungsten particles (WC) was ...
Experimental and numerical research on the failure of railway vehicles coupling links
(Engineering Failure Analysis, 2021)
Two modes of failure are analysed for coupling links, the mechanical connections that transmit traction forces between vehicles along the length of a train. Coupling links are designed to withstand the dynamic loads in ...
Volumetric and Viscometric Study of 1-Hexanol-Based Binary Systems: Experimental Determination and Modeling
(Amer Chemical Soc, Washington, 2020)
Density, viscosity, and refractive index of four binary mixtures with 1-hexanol are experimentally determined at seven temperatures, in the temperature range from 288.15 to 318.15 K and at atmospheric pressure. The choice ...
Thermodynamic study of ester diethyl tartrate and its binary systems with iso-alcohols
(Elsevier, Amsterdam, 2020)
Densities of pure ester diethyl tartrate and alcohols isobutanol and isopentanol are measured on high pressures up to 60 MPa and temperatures from 293.15 K to 413.15 K, while thermophysical properties for two systems ester ...
