Production of Mn3O4 nanoparticles from a manganiferous iron ore via reductive leaching, precipitation, and calcination
(ELSEVIER, 2022)
The synthesis of Mn3O4 nanoparticles from a manganiferous iron ore through reductive leaching, precipitation,
and calcination was investigated. The reductive leaching results showed that Mn (99.9%) was almost completely ...
Microstructure and mechanical properties of dense Si3N4 ceramics prepared by direct coagulation casting and cold isostatic pressing
(ELSEVIER SCIENCE SA, 2022)
Complex shaped dense Si3N4 ceramics were produced by using direct coagulation casting technique via
dispersant reaction method of Si3N4 suspension, followed by gas pressure sintering. The effects of solid content of
the ...
ASSESSMENT OF LOS ANGELES ABRASION VALUE (LAAV) AND MAGNESIUM SULPHATE SOUNDNESS (Mwl) OF ROCK AGGREGATES USING GENE EXPRESSION PROGRAMMING AND ARTIFICIAL NEURAL NETWORKS
(POLSKA AKAD NAUK, POLISH ACAD SCIENCES, 2022)
It has been acknowledged that two important rock aggregate properties are the Los Angeles abrasion value (LAAV) and magnesium sulphate soundness (Mwl). However, the determination of these properties is relatively challenging ...
Assessment of Böhme Abrasion Value of Natural Stones through Artificial Neural Networks (ANN)
(MDPI, 2022)
This present study explored the Böhme abrasion value (BAV) of natural stones through
artificial neural networks (ANNs). For this purpose, a detailed literature survey was conducted to
collect quantitative data on the BAV ...
Diffuse-layer surface potentials of colemanites mined in Turkey
(OFICYNA WYDAWNICZA POLITECHNIKI WROCLAWSKIEJWYBRZEZE WYSPIANSKIEGO 27, 50-370 WROCLAW, POLAND, 2022)
Colemanite crystal specimens were handpicked at Kestelek, Emet (Hisarcik, Espey), Bigadic
mines in Turkey for characterization of their composition and surface potential. X-ray diffraction
analysis revealed no differences ...
Nanoclay- and TiO2 Nanoparticle-Modified Poly( N-vinyl pyrrolidone) Hydrogels: A Multifunctional Material for Application in Photocatalytic Degradation and Adsorption-Based Removal of Organic Contaminants
(ACS Publications, 2022)
In recent times, access to clean water has become increasingly difficult and one of the most important problems for the sustainability of life due to environmental pollution. Based on this thought, in this study, a ...
Interplay between Charge Injection, Electron Transport, and Quantum Efficiency in Ambipolar Trilayer Organic Light-Emitting Transistors
(WILEY, 2022)
The fascinating characteristic of organic light-emitting transistors (OLETs) of being electrical switches with an intrinsic light-emitting capability makes them attractive candidates for a wide variety of applications, ...
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 ...
A Probability-Based Evaluation on Andesites for Their Use as Cladding Stone
(Shahrood University of Technology, 2022)
Andesites with a satisfactory quality have been mainly considered as dimension stones worldwide. However, practical approaches are required to evaluate the dimension stone quality due to the increasing demand for natural ...
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 ...
