Influence of a Low Content of PEO Segment on the Thermal, Surface and Morphological Properties of Triblock and Diblock PCL Copolymers
(Springer, Dordrecht, 2016)
Two series, one of triblock (PCL/PEO/PCL) and the other of diblock (PCL/PEO) copolymers were prepared by ring-opening polymerization of epsilon-caprolactone catalized with tin(II) octoate and by using dihydroxy or monohydroxy ...
Electrochemistry of carbon dioxide corrosion mitigation using tall oil diethylenetriamine imidazoline as corrosion inhibitor for mild steel
(Wiley-VCH Verlag Gmbh, Weinheim, 2016)
The inhibition effect of tall oil diethylenetriamine imidazoline (TOFA/DETA imidazoline) on corrosion of mild steel in CO2-saturated 3wt% NaCl solution was investigated by electrochemical impedance spectroscopy (EIS), ...
Design of biocompatible immobilized Candida rugosa lipase with potential application in food industry
(Wiley-Blackwell, Hoboken, 2016)
BACKGROUNDBiocatalysts are a promising alternative for the production of natural flavor compounds. Candida rugosa lipase (CRL) is a particularly important biocatalyst owing to its remarkable efficiency in both hydrolysis ...
Use of up-flow percolation test to assess the environmental properties of raw and treated fly ash
(Gheorghe Asachi Technical University of Iasi, Romania, 2019)
Fly ash (FA) is a by-product created from the burning of coal in thermal power plants. FA mainly consists of mineral compounds that make them naturally caustic. Despite this, research has shown that FA may be utilized as ...
Ultra-high pressure densification and properties of nanostructured SiC
(Elsevier Science Bv, Amsterdam, 2016)
Cubic SiC nano-powder particles were synthesized by a sal-gel process with an average grains size of 9.5 nm which were subsequently densified by using a high-pressure "anvil-type with hollows" apparatus at a pressure of 4 ...
Volumetric and thermodynamic properties of binary mixtures of p-cymene with alpha-pinene, limonene and citral at atmospheric pressure and temperatures up to 323.15 K
(Journal of Molecular Liquids, 2021)
An experimental analysis of density, refractive index, speed of sound and the viscosity at atmospheric pressure and temperatures T = (288.15 to 323.15) K has been carried out for the three binary systems, i.e. (p-cymene + ...
New Theoretical Insight into Fluorination and Fluorine-Fluorine Interactions as a Driving Force in Crystal Structures
(Amer Chemical Soc, Washington, 2020)
Fluorination of compounds causes an increase in the proton-donating ability and a decrease in the proton-accepting capacity of groups in their vicinity. The formation of F center dot center dot center dot F interactions ...
The re-use potential of espresso spent coffee grounds: Optimization of microwave-assisted extraction of polyphenols by use of response surface methodology and their effects on platelet function - pilot study
(Coffee: Production, Consumption and Health Benefits, 2016)
A huge amount of espresso spent coffee grounds (SCG) are obtained as a waste product during the preparation of coffee beverages (cialdes, K-cups and in metallic filters). Although considered a waste and an ecological threat, ...
Antioxidant edible films based on chitosan and starch containing polyphenols from thyme extracts
(Elsevier Sci Ltd, Oxford, 2017)
The aim of this study was to analyse the antioxidant activity of different polymeric matrices based on chitosan and starch, incorporating a thyme extract (TE) rich in polyphenols. TE provided the films with remarkable ...
Composite nanostructured hydroxyapatite/yttrium stabilized zirconia dental inserts - The processing and application as dentin substitutes
(Elsevier Sci Ltd, Oxford, 2018)
The objective of the study was to process nano-structured hydroxyapatite/yttrium-stabilized zirconia bioceramic and to investigate the possibilities of its application as dentin replacement in the form of dental inserts. ...
