Influence of the electron donor properties of hypericin on its sensitizing ability in DSSCs
(Royal Society of Chemistry, 2019)
Rising demands for renewable energy sources have led to the development of dye sensitized solar cells. It
is a challenge to find a good and low cost sensitizer, which has a low environmental impact. In this work,
we ...
The influence of short thermal treatment on structure, morphology and optical properties of Er and Pr doped ceria pigments: Comparative study
(Faculty of Technology, University of Novi Sad, 2019)
Potential non-toxic pink and red ceramic pigments based on CeO2 were successfully synthesized by selfpropagating room temperaturemethod and thermally treated at 600, 900 and 1200°C for 15min. The structure, morphology and ...
Influence of welding parameters on pit initiation and pit growth in welded joints of X5CrNi18-10 stainless steel
(Springer, 2019)
The influence of welding parameters on the resistance to pitting corrosion in welded joints of X5CrNi18-10 stainless steel was studied. Welding was performed by a TIG procedure in a shielding gas containing different amounts ...
Thin-film four-resistor temperature sensor for measurements in air
(IOP Publishing, 2019)
A temperature sensor based on four thin-film resistors is presented. Four resistors are made in the form of thin metal layer meanders on the surface of a silicon chip. Two resistors are covered with a layer of 2.3 µm thick ...
Oscillatory Carbonylation of Poly(Ethylene Glycol)Methyl Ether Acetylene. Modelling of Reaction Mechanism and Stoichiometric Network Stability Analysis
(University of Kragujevac, 2019)
The reaction mechanism of palladium-catalysed oscillatory carbonylation of
poly(ethylene glycol)methyl ether acetylene (PEGA) was examined by stoichiometric
network analysis (SNA) of the stability of the dynamic states. ...
Furanocoumarin Content, Antioxidant Activity, and Inhibitory Potential of Heracleum verticillatum, Heracleum sibiricum, Heracleum angustisectum, and Heracleum ternatum Extracts against Enzymes Involved in Alzheimer’s Disease and Type II Diabetes
(Willey, 2019)
Hexane extracts of Heracleum verticillatum, H. sibiricum, H. angustisectum, and H. ternatum were studied for their furanocoumarin content antioxidant potential and acetylcholinesterase and α-amylase inhibitory activities. ...
Superior cellulolytic activity of Trichoderma guizhouense on raw wheat straw
(Springer Science and Business Media LLC, 2019)
Lignocellulosic plant biomass is the world’s most abundant carbon source and has consequently attracted attention as a renewable resource for production of biofuels and commodity chemicals that could replace fossil resources. ...
The influence of barium ferrite nanoparticles on morphological and mechanical properties of ethyl cellulose based nanocomposites
(Belgrade : Association for ETRAN Society, 2019)
This study presents preparation and characterization of ethyl cellulose based nanocomposites. Successful use of simple solvent casting technique provided nanocomposites with high loads of barium ferrite magnetic nanopowder ...
Experimental investigation and thermodynamic calculations of the Bi-Ni-Pb phase diagram / Eksperimentalno ispitivanje i termodinamička analiza Bi-Ni-Pb faznog dijagrama
(Beograd : Univerzitet u Beogradu - Tehnički fakultet u Boru, 2019)
The article presents an experimental study of a phase diagram of a ternary Bi-Ni-Pb system using differential thermal analysis (DTA), scanning electron microscopy (SEM) with energy dispersive spectrometry (EDS), and X-ray ...
