Controlled synthesis of monodisperse α-calcium sulfate hemihydrate nanoellipsoids with a porous structure.
We report a facile and green chemical solution approach to synthesize monodisperse α-calcium sulfate hemihydrate (α-HH) nanoellipsoids with a length of 600 nm and a width of 300 nm by simply mixing Ca(2+) and SO4(2-) glycerol-water precursor solutions in the presence of Na2EDTA. The α-HH nanoellipsoid is formed through a Na2EDTA-mediated self-assembly of small primary building blocks (α-HH doma...
متن کاملINVESTIGATING THE RELATIONSHIP BETWEEN HEAT OF HYDRATION AND PHYSICO-MECHANICAL PROPERTIES OF CALCIUM SULFATE HEMIHYDRATE IN THE PRESENCE OF ADDITIVES
This article addresses the interplay between heat of hydration and physico-mechanical properties of calcium sulfate hemi-hydrate in the presence of retarding additives such as citric and malic acids and sodium citrate. The heat of hydration was measured using a semi-isothermal calorimeter. Results proved that citric and malic acids had superior impact on hydration and mechanical properties. Whi...
متن کاملKinetic Modelling of a Pyrolysis – Gasification Reactor
Biomass is of growing interest as a secondary energy source. Biomass could be converted to energy especially by pyrolysis or gasification. Understanding the mechanism and the kinetics of biomass pyrolysis and gasification could be the key to the design of industrial devices capable of processing vast amounts of biomass feedstock. There are multiple reactions describing the decomposition of biom...
متن کاملTheoretical and fuzzy modelling of a pharmaceutical batch reactor
This paper deals with the development of a batch-reactor model with a theoretical and a locally affine fuzzy model. The batch reactor is used in the pharmaceutical industry for the production of drugs, where a rapid and precise temperature control is necessary. The model has to be built to include all the main features necessary for the purposes of modelling. The development of the model for th...
متن کاملModelling and Simulation of a Batch Poly(Vinyl Chloride) Reactor
A population balance model for batch suspension polymerization of vinyl chloride is presented. Break up into two equal volumes of droplets, binary aggregation and random mass exchanges between the colliding droplets are assumed, while the kinetic data of vinyl chloride polymerization are taken from the literature. The model and the process are analyzed by simulation applying a novel Monte Carlo...
