Effect of Potassium Dihydrogen Phosphate Combined with Thermally Activated Nano Serpentine and Thermally Activated Nano Zeolite on Cadmium in Soil
نویسندگان
چکیده
The combined application of potassium dihydrogen phosphate (KH2PO4) and thermally activated nano serpentine KH2PO4 zeolite could immobilize cadmium (Cd) in contaminated soils by increasing soil pH value. results showed that adding nPS700-2.0 (KH2PO4 at 700 °C, 2% addition) exhibited better performance under the same treatment condition; it reduced DTPA-Cd 57.8% exchangeable Cd 48.76%. Adding nPF700 °C) 35.49–44.17% 35.89–42.57%, respectively. increase active adsorption points surface area bioavailability soil, indicating has great potential for immobilization soil.

Nano- and Macroscale Evidence of Thermally Activated Friction
The recent availability of very low wear materials that undergo primarily interfacial sliding has enabled studies that more directly probe the fundamental aspects of friction. This paper reports on variable temperature experiments that were conducted with common polymeric and lamellar solid lubricant materials. Friction coefficient consistently increased with decreased temperature well into the...
متن کاملQuantum effect on thermally activated glide of dislocations.
Crystal plasticity involves the motion of dislocations under stress. So far, atomistic simulations of this process have predicted Peierls stresses, the stress needed to overcome the crystal resistance in the absence of thermal fluctuations, of more than twice the experimental values, a discrepancy best-known in body-centred cubic crystals. Here we show that a large contribution arises from the ...
متن کاملThermally Activated Martensite: Its Relationship to Non-Thermally Activated (Athermal) Martensite
The classification of martensitic displacive transformations into athermal, isothermal or anisothermal is discussed. Athermal does not mean “no temperature dependence” as is often thought, but is best considered to be short for the notion of no thermal activation. Processes with no thermal activation do not depend on time, as there is no need to wait for sufficient statistical fluctuations in s...

متن کاملThermally activated conductivity in gapped bilayer graphene
This is a theoretical study of electron transport in gated bilayer graphene — a novel semiconducting material with a tunable band gap. It is shown that the quantum mechanical superposition between conduction and valence band states enhances the subgap conductivity and facilitates the thermally activated transport. The mechanism proposed can also lead to the non-monotonic conductivity vs. temper...
