Physical properties of chemically conditioned sludges
… objectives of this study were to quantify the physical properties of sludges following chemical conditioning by a variety of conditioning chemicals. Water and wastewater sludge samples from full-scale Blacksburg water and wastewater treatment plants were used. The iron sludge was made in the …

Chemistry and physical properties of axinites
Electron microprobe analyses of 37 axinites substantiate the conclusions of Sanero and Gottardi (1968) as to the substitutional solid solution between octahedrally coordinated divalent cations Ca, Fe, and Mn. The analyses also suggest the substitution of Fe³⁺ for Al in the AlO₅(OH) octahedra for …

Evaluation of physical properties of ionic liquids
Firstly, experimental data for ionic liquids properties; density, viscosity of pure ionic liquids, viscosity of binary ionic liquid mixtures, and solubility in molecular solvents were collected from the literature and thus four databases were compiled. Then mathematical gnostics was used to analyse …

The Chemical and Physical Properties of Tourmaline
The decomposition temperature of schorl was found to be 880 ± 10°C using X-ray and optical methods. The main crystalline product in decomposed schorl and dravite was found to be a boron containing mullrte, the composition of this phase was found to become closer to that of mullite (3Al203.2Si02) as …

Physical properties of alkanes and their mixtures
Alkanes and their mixtures are some of the physically simplest molecules and are widely used in industry, yet the connection between their structure and physical properties is still poorly understood. To make progress, we study the properties of pure alkanes with neural networks and molecular …

Structure and Physical Properties of Hydrogrossular Mineral Series
… modeling to investigate the structures and properties for hydrogrossular series for x = 0, 0.5, 1, 1.5, 2, 2.5, 3. Results indicate that for x > 0 and x < 3, the structures are tetragonal. This shows that there is structural change related to the lowering of overall symmetry associated with …

Multiphase Galactic Outflows: Physical Properties and Feedback Effects
… In the first part of this thesis, I study the physical mechanisms driving outflows as well as whether outflows are capable of suppressing star formation using a study of molecular gas outflows with ALMA and archival data. In a sample of 50 local galaxies with outflow signatures in low-J carbon …

Studies of physical properties of novel lithium polymer electrolytes.
… polymer electrolyte system. The mechanical properties of the systems showed that at low plasticiser content the stiffiless of the polymer electrolytes is less affected but has a low ionic conductivity. In summary, results from SEM spectroscopic data in conjunction with thermal analysis show …
