Flocs generated in various aluminum coagulants treatment exhibit difference in size, strength and structure. The formation, breakage and re-formation of flocs were investigated by using a laser diffraction instrument (Malvern Mastersizer 2000, Malvern, UK). Different Al coagulants--conventional Al salt (AlCl(3)), polyaluminum chloride (PAC-1) and the(More)
In this paper, we use density functional theory to study the effect of the charge of solvophilic beads and concentration on the mesoscale structures of polyelectrolyte solution. The polyelectrolyte A6B12A6 was selected as the triblock polymer, and the solvophobic B blocks have no charges, while the solvophilic A blocks are charged. The simulation results(More)
Si<sub>x</sub>Ge<sub>1-x</sub> is typical thermoelectric materials used for higher temperature as thermoelectric generator. Their property is dependent on their composition. Here different dopants, including P, Ga, B, GaP, In, Sb and InSb, were used to investigate their effect on the thermoelectric properties of n type Si<sub>80</sub>Ge<sub>20</sub> alloys.(More)
The effect of Ca(2+) and Mg(2+) on the H-bonding structure around the headgroup of the surfactants sodium dodecyl sulfate (SDS) and sodium dodecyl sulfonate (SDSn) in solution has been studied by molecular dynamics simulation. Our results show that binding between the headgroup of the surfactant and Ca(2+) or Mg(2+) is prevented by a stabilizing(More)
Ni<sub>x</sub>Co<sub>4-x</sub>Sb<sub>12</sub> (x = 0.02~0.1) was fabricated by ultra high-pressure method. Composition, thermoelectric properties and the microstructure were investigated. The results indicate that Ni<sub>x</sub>Co<sub>4-x</sub>Sb<sub>12</sub> (x = 0.02~0.1) fabricated by ultra high pressure sintering has good thermoelectric properties. Low(More)
