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 ...
Preparation and characterization of novel P(HEA/IA) hydrogels for Cd2+ ion removal from aqueous solution
(Elsevier Science Bv, Amsterdam, 2015)
Series of novel hydrogels based on 2-hydroxyethyl acrylate (HEA) and itaconic acid (IA), P(HEA/IA) copolymers, were prepared by free radical cross-linking copolymerization and investigated as potential adsorbents for Cd2+ ...
Composite poly(DL-lactide-co-glycolide)/poly(acrylic acid) hydrogels synthesized using UV and gamma irradiation: comparison of material properties
(Pergamon-Elsevier Science Ltd, Oxford, 2020)
Composite hydrogels capable of controlled drug delivery via ion exchange are an interesting group of materials for the construction of implantable drug reservoirs for electrically charged drugs. In this study, we synthesized ...
Second harmonic generation at the quantum-interference induced transparency in semiconductor quantum wells: The influence of permanent dipole moments
(IEEE-Inst Electrical Electronics Engineers Inc, Piscataway, 2001)
The influence of permanent dipole moments of quantized states on intersubband second harmonic generation based on quantum-interference induced transparency in semiconductor quantum wells is explored using the harmonic ...
Gain-maximized GaAs/AlGaAs quantum-cascade laser with digitally graded active region
(Amer Inst Physics, Melville, 2002)
An advanced strategy for the optimal design and realization of a GaAs/AlGaAs quantum-cascade laser is presented. It relies on recently established inverse scattering techniques to design an optimal smooth active region ...
Impedance analysis of milk quality using functionalized polyamide textile-based sensor
(Computers and Electronics in Agriculture, 2021)
Present paper demonstrates design and characterization of a textile based microfluidic chip sensor for the detection of milk adulteration through measuring the real part of the impedance and impedance phase angle. Polyamide ...
On the interdiffusion-based quantum cascade laser
(IEEE-Inst Electrical Electronics Engineers Inc, Piscataway, 2002)
Design procedure for the active region of current pumped quantum cascade laser is proposed, so to achieve maximal gain. Starting with an arbitrary smooth potential, a family of isospectral Hamiltonians with predefined ...
A generic concept to overcome bandgap limitations for designing highly efficient multi-junction photovoltaic cells
(Nature Publishing Group, London, 2015)
The multi-junction concept is the most relevant approach to overcome the Shockley-Queisser limit for single-junction photovoltaic cells. The record efficiencies of several types of solar technologies are held by series-connected ...
Characterization of sodium alginate/D-limonene emulsions and respective calcium alginate/D-limonene beads produced by electrostatic extrusion
(Elsevier Sci Ltd, Oxford, 2015)
In this study, calcium alginate beads immobilizing D-limonene (solid systems) have been manufactured starting from emulsions of this flavor in sodium alginate (liquid systems). The effects of alginate concentration (0.02 ...
In vitro evaluation of enzymatically derived blackcurrant extract as prebiotic cosmetic ingredient: extraction conditions optimization and effect on cutaneous microbiota representatives
(Springer Science and Business Media Deutschland GmbH, 2023)
Background Blackcurrant is a rich source of polyphenols with proven physiological activity, that have lately been classified as emerging prebiotics, making its extracts suitable for application in functional food and ...
