Contribution of marine and continental aerosols to the content of major ions in the precipitation of the central Mediterranean
(Elsevier, 2006)
The region of the investigated receptor is situated in the southern part of the Adriatic Sea in the Mediterranean. The measuring station is located on the seashore, which, being considered as a border area, is representative ...
Heat capacities and thermodynamic functions of neodymia and samaria doped ceria
(Elsevier, 2021)
Doped ceria materials are ionic conductors currently under investigation for use in solid oxide fuel cells, catalysts, and other applications. We measured the heat capacity of several doped ceria samples from 1.8 K to 300 ...
Application of Iridium Catalized Allylic Substitution Reactions in the Synthesis of Branched Triptamines and Homologues via Tandem Hydroformylation/Fischer Indole Synthesis
(Royal Society of Chemistry, 2008)
Combination of enantioselective allylation reactions with a tandem hydroformylation–Fischer indole synthesis sequence as a highly diversity-oriented strategy for the synthesis of tryptamines and homologues was explored. ...
Syntheses of Tetrahydro-β-Carbolines via Tandem Hydformylation / Pictet-Spengler Reaction, Scope and limitations
(Royal Society of Chemistry, 2008)
A novel one-pot synthesis of tetrahydro-β-carboline systems via tandem hydroformylation–Pictet–Spengler reaction starting from olefins and aryl ethylamines is described. This tandem procedure allows fast and convenient ...
Change of water redox potential, pH and rH in contact with magnesium enriched kaolinite–bentonite ceramics
(Elsevier, 2008)
It was established that the addition of Mg to the mixtures of kaolinite and bentonite can provide clay compositions which, after
sintering at high temperatures, produce very porous ceramics with microcrystalline and ...
A study of Roman glass from Mala Barutana/Belgrade Fortress irradiated with pulsed CO2, Nd:YAG and ruby laser — Comparison
(Elsevier, 2012)
Application of non-contact and rapid laser technique, which is minimally invasive, non-contaminant and efficient method, for ancient glass investigation and cleaning is highly desirable for restoration purposes. Irradiation ...
Direct Visualization of Charge-Extraction in Metal-Mesh Based OPV Cells by Light-Biased LBIC
(Institute of Electrical and Electronics Engineers (IEEE), 2017)
Metal-mesh based electrode systems are a highly conductive, versatile, and inexpensive alternative to ITO-electrodes for organic photovoltaic (OPV) cells. However, they do not offer full surface conductivity and are, ...
In vitro investigation of electrophoretically deposited bioactive hydroxyapatite/chitosan coatings reinforced by graphene
(Elsevier, 2017)
Graphene (Gr) and natural polymer chitosan (CS) were introduced to hydroxyapatite (HAP) to produce a three-component composite coating, which was fabricated by cathodic electrophoretic deposition on Ti substrates in an ...
Influence of film formation on light-trapping properties of randomly textured silicon thin-film solar cells
(The Japan Society of Applied Physics, 2014)
The influence of film formation on light-trapping properties of silicon thin-film solar cells prepared on randomly textured substrates was studied. Realistic interface morphologies were calculated with a three-dimensional ...
A Potential Source of Free Radicals in Iodine-Based Chemical Oscillators
(American Chemical Society (ACS), 2011)
The iodide-peroxide system in an acidic medium was investigated as a potential source of free radicals in iodine-based chemical oscillators. The radicals were detected by EPR spintrapping using spin-trap 5-(tert-butoxyca ...
