Possibilities of elimination of ammonia slip from technological water in power plants
(IOP Publishing, 2018-07-12)
The purpose of this study is to find new possibilities of elimination or separation of ammonium compounds from technological water produced by powerplants and incinerators, in which the secondary flue gas denitrification ...
Release of ammonia from conventional power plant fly ash after the introduction of SNCR process
(IOP Publishing, 2018-07-12)
The paper deals with a study of various factors affecting the release of ammonia from conventional power plant fly ash after introduction of SNCR (Selective non-catalytic reduction). SNCR is a method of flue gas denitrification ...
Effect of Quench Environment on the Conversion Coatings on Magnesium Alloy AZ91
(Mendel University Press, 2018-02-28)
The aim of the study is to achieve fine microstructure of AZ91, due to the optimized heat treatment processes, which can be easily coated with a normal conversion process as phosphating. Determination of the influence of ...
Density of bulk trap states of hybrid lead halide perovskite single crystals: temperature modulated space-charge-limited-currents
(Springer Nature, 2019-03-04)
Temperature-modulated space-charge-limited-current spectroscopy (TMSCLC) is applied to quantitatively evaluate the density of trap states in the band-gap with high energy resolution of semiconducting hybrid lead halide ...
The influence of barium sulphate and barium carbonate on the Portland cement
(Elsevier Ltd., 2016-08-03)
Shielding of different types of radiation should be studied these days when there is a great development in the field of nuclear science. Barium ions can shield different type of radiation, therefore, by incorporation of ...

Evaluation of the Surfactant Leaching from Alkali-Activated Slag-Based Composites Using Surface-Tension Measurements
(Institute of Metals and Technology, 2019-02-01)
This work tries to evaluatethe amount of surfactant leached from the AAS-based mortars using a very simple surface-tension (ST) measuring technique.Mortars based on AAS with and without2%ofPEGvarying in molecular weight ...
The Characterization of Fixation of Ba, Pb, and Cu in Alkali-Activated Fly Ash/Blast Furnace Slag Matrix
The fixation of heavy metals (Ba, Cu, Pb) in an alkali-activated matrix was investigated. The matrix consisted of fly ash and blast furnace slag (BFS). The mixture of NaOH and Na-silicate was used as alkaline activator. ...
Effect of Na3PO4 on the Hydration Process of Alkali-Activated Blast Furnace Slag
In recent years, the utilization of different non-traditional cements and composites has been increasing. Alkali-activated cementitious materials, especially those based on the alkali activation of blast furnace slag, have ...
