Synthesis and rheological study of some maleic acid and fumaric acid stereoregular polyesters - 8. Unsaturated polyester fibers
(Springer, New York, 1992)
First unsaturated polyester fibers were prepared starting from stereoregular, macromolecular poly(octamethylene fumarate). Fibers obtained from octamethylene copolyesters of fumaric and terephthalic acids manifested improved ...
Supercritical and ultrasound-assisted extracts fromPleurotus pulmonariusmushroom: chemical profiles, antioxidative, and enzyme-inhibitory properties
(Wiley, Hoboken, 2021)
Background This study provides an insight into the impact of ultrasound-assisted extraction with water as solvent (UAEW) and extraction by supercritical carbon dioxide (SC-CO2) with 5% EtOH on antioxidant and enzyme ...
Predicting Low-Modulus Biocompatible Titanium Alloys Using Machine Learning
(MDPI, 2023)
Titanium alloys have been present for decades as the main components for the production of various orthopedic and dental elements. However, modern times require titanium alloys with a low Young’s modulus, and without the ...
Synthesis of mullite nanostructured spherical powder by ultrasonic spray pyrolysis
(Pergamon-Elsevier Science Ltd, Oxford, 1998)
In this paper the synthesis of nanostructured spherical particles of mullite powders by ultrasonic spray pyrolysis is presented. The mullite crystallization and the nanostructure development during heating were examined ...
Formic acid oxidation on pure and Bi-modified Pt(111): Temperature effects
(Amer Chemical Soc, Washington, 2000)
Temperature effects on the kinetics of formic acid electrooxidation are studied on Pt(111) and on Pt(111) modified by irreversibly adsorbed Bi under both potentiodynamic and potentiostatic conditions. We propose two modes ...
Electrooxidation of H-2, CO, and H-2/CO mixtures on a well-characterized Pt70Mo30 bulk alloy electrode
(Amer Chemical Soc, Washington, 1998)
The electrochemical oxidation of hydrogen (H-2), carbon monoxide (CO), and their mixtures (500 ppm-2%) on a well-characterized Pt70Mo30 bulk alloy was examined using the rotating disk electrode technique in 0.5 M H2SO4 at ...
Influence of the synthesis parameters on the properties of the sepiolite-based magnetic adsorbents
(Elsevier Science Bv, Amsterdam, 2017)
The magnetic nanocomposites (MNCs), used as adsorbents for Cd2+ ions, were prepared by a co-precipitation method using both the untreated natural (SEP) and the partially acid-activated (ASEP) sepiolites as supports for ...
Solids holdup and pressure drop in gas-flowing solids-fixed bed contactors
(Amer Chemical Soc, Washington, 2003)
Fundamentally based model for pressure drop in gas-flowing solids-fixed bed contactors is presented, together with a phenomenological semiempirical model for prediction of dynamic holdup. These simple models do not require ...
Lead spatio-temporal pattern identification in urban microenvironments using moss bags and the Kohonen self-organizing maps
(Pergamon-Elsevier Science Ltd, Oxford, 2015)
The first investigation of the use of the Kohonen self-organizing map (SOM) which includes lead concentration and its isotopic composition in moss bags to assess the spatial and temporal patterns of lead in the urban ...
Antimicrobial activity of celery fruit isolates and SFE process modeling
