Assessment of Efficiency of Rare Earth Elements Recovery from Lignite Coal Combustion Ash via Five-Stage Extraction
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2021)
Rare earth elements (REE) are frequently referred to as ingredients for enhancements in modem industry, as they are extensively applied in many industrial branches due to their accented electro-magnetic and optical properties. ...
Prediction model based on artificial neural network for pyrophyllite mechano-chemical activation as an integral step in production of cement binders
(Elsevier Sci Ltd, Oxford, 2020)
The optimal outputs of pyrophyllite mechano-chemical activation in an ultra-centrifugal mill performing under different technological conditions were determined by analytical modeling and verified via Artificial Neural ...
Potential pathway for recycling of the paper mill sludge compost for brick making
(Elsevier Sci Ltd, Oxford, 2021)
This study's focus was to develop a potential pathway for recycling of the paper mill sludge compost (PMSC) in brick making. Composting reduces the paper mill sludge (PMS) moisture content considerably and shredding becomes ...
What is the most relevant method for water absorption determination in ceramic tiles produced by illitic-kaolinitic clays? The mystery behind the gresification diagram
(Sociedad Espanola de Ceramica y Vidrio, 2020)
This study presents the 51 mixtures of ceramic clays characterized by using XRF, XRD, granulometry, and dilatometry analyses. After firing in a 1000-1250 °C range, water absorption (WA) according to EN standards by boiling ...
Fired pressed pellet as a sample preparation technique of choice for an energy dispersive X-ray fluorescence analysis of raw clays
(Elsevier, 2022)
In this paper, the main subject concerns comparing different techniques to prepare raw clay samples for energy dispersive X-ray fluorescence spectrometry (EDXRF). Three kinds of sample preparation procedures are examined,such ...
Life Assessment of Corroded Wire for Prestressing
(MDPI, 2023)
The repair of structural elements for the prestressing of reinforced concrete is necessary
when existing prestressing wires are damaged or after a certain period of time. The objective of this
paper is to describe the ...
Structure and properties of ZnO/ZnMn2O4 composite obtained by thermal decomposition of terephthalate precursor
(Journal of the Serbian Chemical Society - JSCS, 2022)
A biphasic [Mn(dipya)(H2O)4](tpht)/{[Zn(dipya)(tpht)]·H2O}n complex material, I, (dipya = 2,2’-dipyridylamine, tpht2– = dianion of terephthalatic acid) was synthesized by ligand exchange reaction and characterized by XRPD ...
Failure analysis of ATR 72 tow bar–opportunity for re-design for inspection
(10th EASN Virtual International Conference on Innovation in Aviation & Space to the Satisfaction of the European Citizens, 2020)
The safe towing of aircraft is an important part in aviation security. Failures during the towing and parking
related operations are not so rare due to bad working circumstance, human error, etc. Tow bars are simple
but ...
Raw kaolinitic–illitic clays as high‑mechanical‑performance hydraulically pressed refractories
(Journal of Thermal Analysis and Calorimetry, 2022)
The usage possibility of 19 composites of raw refractory clays from Serbia containing approximately 53.29% of SiO2 and 26.73% of Al2O3 is presented. The sum of fluxing oxides was 57.74%, while these materials contained 32% ...
