Monolayer polymer photocells. The opportunities
(
Academy of Sciences and Arts of the Republic of Serbia
, 2015 , Article)
The conversion of solar energy into electricity is in the focus of a large number of scientists. Because of the problems caused by the use of fossil fuels, the use of renewable and environmentally friendly energy sources ...
Effect of layered silicates on the thermal stability of PCL/PLA microfibrillar composites
(
Elsevier
, 2016 , Article)
This paper reports on an investigation of the influence of the presence of two different clays, Cloisite 15A
and Cloisite 30B, and fibre drawing on the degradation behaviour and kinetics of PCL/PLA composites. It
was ...
Influence of the Ce :YAG amount on structure and optical properties of Ce :YAG-PMMA composites for white LED
(
De Gruyter
, 2016 , Article)
Ce:YAG-poly(methyl methacrylate) (PMMA) composites were prepared by using a melt compounding method, adding several amounts of Ce:YAG in the range 0.1–5wt.%. The optical properties of the obtained composites and of the ...
Electrospun alginate nanofibres impregnated with silver nanoparticles: Preparation, morphology and antibacterial properties
(
Elsevier
, 2017 , Article)
Abstract Silver nanoparticles are amongst the most valuable nanoparticles with interesting properties, such as a non-toxic nature and high antibacterial efficiency, making them applicable for tissue scaffold, protective ...
Morphology and magnetic properties of the ethylene-co-vinyl acetate/iron nanocomposite films prepared by implantation with Fe6+ ions
(
Elsevier
, 2016 , Article)
Ethylene-co-vinyl acetate/iron nanocomposite films were fabricated by implantation with multiplecharged ions at different fluencies. The films obtained with ion fluency of 1 × 1017cm−2were used forspecific studies. It was ...
Investigation of the physico-mechanical properties of electrospun PVDF/cellulose nanofibers.
(
Wiley
, 2016 , Article)
The electro-activity and mechanical properties of PVDF depends mainly on the b-phase content and degree of crystallinity. In this study, cellulose fibers were used to improve these characteristics. This could be achieved ...
Preparation and characterisation of Ce:YAG -polycarbonate composites for white LED
(
Elsevier
, 2016 , Article)
Ce:YAG-polycarbonate composites were prepared with several amounts of Ce:YAG in the range 0.1–5 wt.% by using melt compounding. The structure and morphology of the composites were investigated by means of X-ray diffractometry ...
Direct electroreduction of indium and tin oxides in molten salts
(
Electrochemical Society Inc.
, 2014 , Article)
Indium is a rare metal. The largest end use for indium is in thinfilm coatings as indium oxide combined with 10 percent tin oxide (ITO). However, indium has recycling rates less than 1%. Indium and tin are especially well ...
One-dimensional facile growth of MAPbI3 perovskite micro-rods
(
Royal Society of Chemistry
, 2019 , Article)
One-dimensional microrods (4–5 mm) of PbI2 and CH3NH3PbI3 (MAPbI3) with unique structural and morphological properties have been grown at room temperature. X-ray diffraction (XRD) patterns of both types of micro-rods exhibit ...
Grain refining and improving mechanical properties of a warm rolled AZ31 alloy plate
(
Elsevier B.V.
, 2014 , Article)
The mechanical properties of an AZ31 magnesium alloy were improved after warm rolling. The study involved a pre-rolling condition in which the material consisted of twins, playing a key role in recrystallization grain ...
