Determination of Critical Parameters of Drug Substance Influencing Dissolution: A Case Study
(Hindawi Publishing Corporation, 2014-09-15)
The purpose of this study was to specify critical parameters (physicochemical characteristics) of drug substance that can affect dissolution profile/dissolution rate of the final drug product manufactured by validated ...
The field of solid solutions in ternary system of synthetic apatite-type alkaline earth element-yttrium-silicate oxybritholite phases of the composition: AEE(delta)Y(10-delta)[SiO4](6)O3-0.5 delta, where AEE=Ca, Sr and Ba
(Elsevier Ltd, 2016-01-08)
This contribution deals with the synthesis, properties and investigation of the field of solid solutions formed between the three end-members of apatite-type alkaline earth element-yttrium-silicate oxybritholites with the ...
The formation of feldspar strontian (SrAl2Si2O8) via ceramic route: Reaction mechanism, kinetics and thermodynamics of the process
The reaction mechanism, the equilibrium composition, the temperature range of stability of formed intermediates as well as the kinetics and thermodynamics of activated state during the formation of monoclinic strontium-a ...
The influence of starting materials´ solubility on tobermorite structure formation under the hydrothermal conditions
(IOP Publishing, 2018-07-12)
Overall, the tobermorite mineral crystallises under the hydrothermal conditions from the CaO-SiO2-H2O system. The system of calcium hydrosilicates species is extremely complex and many factors play an important role. The ...
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 ash from fluidized bed combustion as a donor of sulfates to the Portland clinker
The paper deals with possibilities of using solid residues from fluidized bed combustion of coal, bed and filter ash in the production of composite Portland cements. The ash from fluidized bed combustion contains a high ...
