Broadband Low Reflection Surfaces with Silicon Nanopillar Hexagonal Arrays for Energy Harvesting in Photovoltaics
(SPRINGER, 2022)
In this study, optimization of the silicon nanopillar arrays and thin films coated on silicon substrate has been investigated in order to minimize the optical reflection loss from the silicon substrate surface. Nanopillars’s ...
Indenofluorenes for organic optoelectronics: the dance of fused five- and six-membered rings enabling structural versatility
(Royal Society of Chemistry, 2022)
Polycyclic π-conjugated hydrocarbons (PCHs), either unfunctionalized or structurally modified derivatives, have attracted tremendous interest in the past few decades as high-performance semiconductors for use in new ...
Separation of Mn and Fe from a Manganiferous Iron Ore Using Horse Dung as Reductant: A Zero Waste Approach
(SPRINGER, 2022)
The separation of manganese and iron from a manganiferous iron ore using horse dung (biomass) as reductant was investigated in a sulfuric acid solution, and 99.80% Mn and 17.76% Fe were extracted into the solution under ...
Assessment of Deformation Properties of Coal Measure Sandstones Through Regression Analyses and Artificial Neural Networks
(Polska Akademia Nauk, 2021)
The deformation properties of rocks play a crucial role in handling most geomechanical problems.
However, the determination of these properties in laboratory is costly and necessitates special equipment.
Therefore, many ...
The surface charge of unsupported nano-structured titania ceramic membrane top layers with varying calcination temperatures
(University of Chemical Technology and Metallurgy, 2019)
Titania is one of the most preferable ceramic membrane materials of superior durability (as zirconia) when compared to that of other ceramics, e.g. alumina or silica. The surface charge of the membrane top layer is an ...
On the variation in several rock properties due to magnesium sulfate weathering tests ‒ a case study for limestones
(International Multidisciplinary Scientific Geoconference, 2019)
Contributions to the behavior of rock materials under various conditions provide a practical knowledge about issues relating the performance and long-term serviceability of rocks. In this study, various limestones with ...
An experimental investigation on rock crushability using jaw and cone crushers
(Baski, 2019)
This study covers the investigation of rock crushability using laboratory-scale cone and jaw
crushers for five types of hardrocks. For this purpose, physico‒mechanical properties of the investigated
rocks are determined. ...
Leaching of yahyali non-sulphide PB-ZN flotation tailing using organic acids
(Baski, 2019)
The laboratory scale leaching of Kayseri-Yahyali non-sulphide lead (Pb)-zinc (Zn) flotation tailing using two organic acids was experimentally investigated. The effect of citric and oxalic acid on the dissolution of Zn, ...
Color Simulation and Demonstration of Perovskite Nanocrystal Filters for Wide Color Gamut Displays
(Institute of Electrical and Electronics Engineers Inc., 2018)
In this study, we define spectral parameters of perovskite nanocrystals to improve LCD color gamut, replacing color filters (CFs) with perovskite based subpixels. The optimization of the CFs has been enhanced 15.8% (98.43% ...
Arrays of multi-color emitting cesium lead halide perovskite nanocrystals and efficient white light generation by tailored anion exchange reactions and electrohydrodynamic jet printing
(Optica Publishing Group (formerly OSA), 2018)
We employ highly efficient and narrow band emitter Cesium-lead-halide perovskite nanocrystals, optimized by the anion exchange method, for efficient white light generation by patterning multiple lines of different colors ...
