Influence of hemicelluloses and lignin content on structure and sorption properties of flax fibers (Linum usitatissimum L.)
(Springer, Dordrecht, 2018)
In this work, alkali and oxidative treatments were employed to obtain flax fibers with different content of hemicelluloses and lignin, in order to study the influence of chemical composition on structure and sorption ...
Optical properties of composite restorations influenced by dissimilar dentin restoratives
(Elsevier Sci Ltd, Oxford, 2018)
Objectives. To evaluate optical properties (color and translucency) of 'sandwich' restorations of resin-based composites and esthetically unfavorable dentin restoratives. Methods. Cylindrical 'dentin' specimens (8 mm in ...
Experimental design of the Cu-As-Sn ternary colour diagram
(Academic Press Ltd- Elsevier Science Ltd, London, 2018)
The aesthetic appearance of metals has long been recognised in archaeometric studies as an important factor driving inventions and innovations in the evolution of metal production. Nevertheless, while studies of ancient ...
Antibacterial activity of Cu-based nanoparticles synthesized on the cotton fabrics modified with polycarboxylic acids
(Elsevier Sci Ltd, Oxford, 2018)
The fabrication of antimicrobial textile nanocomposite by in situ synthesis of Cu-based nanoparticles on cotton fabrics modified with different polycarboxylic acids was discussed in this study. In order to evaluate the ...
Alginate/soy protein system for essential oil encapsulation with intestinal delivery
(Elsevier Sci Ltd, Oxford, 2018)
Preparation of alginate-soy protein isolate (AL/SPI) complex beads containing essential oil of thyme was carried out by emulsification of thyme oil in aqueous sodium alginate solution blended with SPI solution, followed ...
Mesoporous Silica and Organosilica Nanomaterials as UV-Blocking Agents
(Amer Chemical Soc, Washington, 2018)
Mesoporous silica nanoparticles (MSN) and periodic mesoporous organosilica nanoparticles containing bridging benzene (PMOBTB) and ethane (PMOBTE) moieties are synthesized, characterized, and evaluated for application in ...
Development of material with strong antimicrobial activity by high pressure CO2 impregnation of polyamide nanofibers with thymol
(Elsevier Sci Ltd, Oxford, 2018)
This study discusses the potential of high pressure (supercritical and liquid) CO2 impregnation to load electrospun polyamide nanofibers with thymol as an antimicrobial agent. The influence of selected pressures and ...
Achieving high antimicrobial activity: Composite alginate hydrogel beads releasing activated charcoal with an immobilized active agent
(Elsevier Sci Ltd, Oxford, 2018)
New composites based on Ca-alginate hydrogels were produced that release activated charcoal (AC) particles with adsorbed povidone iodine (PVP-I) as a model antimicrobial substance in a physiological-like environment. ...
Urtica dioica L. leaf extract modulates blood pressure and oxidative stress in spontaneously hypertensive rats
(Elsevier Gmbh, Urban & Fischer Verlag, Jena, 2018)
Background: Urtica dioica L. (Stinging nettle) has been used for centuries for the treatment of numerous health issues. Purpose: This study investigates the antioxidant capacity and the most abundant phenolic compounds of ...
Composite materials from fully bio-based thermosetting resins and recycled waste poly(ethylene terephthalate)
(Elsevier Sci Ltd, Oxford, 2018)
During the last two decades, interest in bio-based polymers, especially in bio-based composite materials, has grown as a result of environmental concerns. In this paper new composites obtained from fully bio-based unsaturated ...
