Alkali activated slag cement doped with Zn-rich electric arc furnace dust
(Elsevier, 2020)
Steel production in electric arc furnaces yielding formation of two waste materials, toxic electric arc furnace dust (EAFD) and non-hazardous electric arc furnace slag (EAFS). EAFD presents a potential hazard to the ...
In-depth quantitative profiling of post-translational modifications of Timothy grass pollen allergome in relation to environmental oxidative stress
(Pergamon-Elsevier Science Ltd, Oxford, 2019)
An association between pollution (e.g., from traffic emissions) and the increased prevalence of respiratory allergies has been observed. Field-realistic exposure studies provide the most relevant assessment of the effects ...
Dispersion effect in formic acid oxidation on PtAu/C nanocatalyst prepared by water-in-oil microemulsion method
(Elsevier Science Bv, Amsterdam, 2019)
Low loading PtAu nanoparticles supported on high area carbon were synthesized by water-in-oil microemulsion method and examined for formic acid and methanol oxidation. Prepared catalyst powder was characterized by Xray ...
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 ...
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 ...
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 ...
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 ...
Catalytic hydrogenation reaction micro-kinetic model for dibenzyltoluene as liquid organic hydrogen carrier
(Elsevier Ltd., 07-2024)
The implementation of the liquid organic hydrogen carrier (LOHC) technology for efficient energy storage requires the development of a reliable kinetic model for both hydrogenation and dehydrogenation processes. In this ...
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 ...
RuxTi1-xO2 as the support for Pt nanoparticles: Electrocatalysis of methanol oxidation
(Elsevier, Amsterdam, 2015)
Two binary Ru-Ti oxides, Rum Ti0.9O2 and Ru0.7Ti0.3O2, were synthesized by the sol-gel method and used as an electrocatalyst support. The system was characterized by XRD, EDS, TEM and cyclic voltammetry. The Rum Ti0.9O2 ...
