2. 1. Towards the Improvement of Salt Extraction from Lake Katwe Raw Materials in Uganda

   Author : Hillary Kasedde; Pär Jönsson; Anders Tilliander; Eric Forssberg; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lake Katwe; salt extraction; brine; evaporites; saltpan; characterization; evaporation - crystallization; solubility; Pitzer ’s ion - interaction model; PHREEQC software; dissolution kinetics; Avrami model.;

   Abstract : Uganda is well endowed with economic quantities of mineral salts present in the interstitial brines and evaporite deposits of Lake Katwe, a closed (endorheic) saline lake located in the western branch of the great East African rift valley. Currently, rudimentally and artisanal methods continue to be used for salt extraction from the lake raw materials. READ MORE

4. 2. Model for activity coefficients and solubilities of Na2CO3 and Na2SO4 in high-temperature solutions

   Author : Marta Anna Bialik; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; scaling; Pitzer model; activity coefficient; solubility; sodium carbonate; sodium sulfate; boiling point raise; double salt; solid solution; burkeite;

   Abstract : Scaling of sodium sulfate and sodium carbonate double salts has long been recognized as a problem in the black liquor evaporation process. These salts are abundant in black liquor and often tend to precipitate on heat transfer areas, thereby significantly decreasing the heat transfer efficiency. READ MORE

5. 3. On the Thermodynamic Solvation of Biomolecules in Solution

   Author : Stefan Hervö Hansen; Beräkningskemi; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Solubility; Solvation; Aggregation; Statistical thermodynamics; Molecular dynamics; Monte Carlo simulations; Free energy calculations; Energy-representation theory of solvation; Proteins; Salt bridges; Caffeine;

   Abstract : The topic solvation thermodynamics is an important aspect of chemistry, dealing with the effects introduced by solvents onto solutes. In particular, biological systems are highly heterogeneous in their choice of solvent typically characterized by either being in a polar or non-polar environment. READ MORE

6. 4. Innovative process solutions towards recycling of salt cake from secondary aluminum smelting

   Author : Peng Li; Lidong Teng; Sankaran Subramanian; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermal diffusivity; Model; Solubility; CO2; AlN; Crystals; Hydrolysis; Enhance; Hinder; Leaching; Absorption; Synthesis; SiMgAlON; Oxidation; Arctan; Activation energy; Mullite; Liquid; Crystallization.; SRA - Production; SRA - Produktion;

   Abstract : To offer better solutions for the recycling of salt cake from secondary aluminum melting, several innovative investigations were carried out based on hydrometallurgical and pyrometallurgical views.Thermal diffusivity measurements as a function of temperature on salts-Al composites having various compositions (0, 2, 4, 6, 8, 10, 12wt pct metallic Al) were carried out.

7. 5. Molten Salt Electrolytes for Calcium Batteries

   Author : Johanna Timhagen; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Batteries; Metal anodes; Molten salt electrolytes; Calcium;

   Abstract : Batteries are in higher demand than ever before as well as increased requirements in terms of energy and power density. The desire for higher energy density has meant that electrolytes are pushed above their electrochemical stability limits and hence they decompose, but typically this is under control and a new beneficial phase is created at the electrode surface; the solid electrolyte interphase (SEI).
