Ion cyclotron instability due to the thermal anisotropy of drifting ion species
(Blackwell Publishing Ltd, 2003)
In a recent study of ion cyclotron waves generated by the thermal anisotropy of oxygen ions, it was shown that the heavy ion drift velocity and a large thermal anisotropy of the heavy ions can destabilize proton-cyclotron ...
Ion cyclotron instability triggered by drifting minor ion species: Cascade effect and exact results
(2004)
On the basis of bi-Maxwellian velocity distribution functions it has been recently shown that the combined effect of heavy ion thermal anisotropy and drift velocity can trigger ion-cyclotron instabilities beyond the ...
The application of diffusion–reaction mixed model to assess the best experimental conditions for bark chemical activation to improve copper(II) ions adsorption
(Springer-Verlag, 2014)
Natural sorbents have been thoroughly assessed
to determine their adsorption capabilities to remove pollutants
from industrial wastewaters. Among them, pine
bark has demonstrated potential for carrying out the
removal ...
Graphene Oxide-ZnO Nanocomposites for Removal of Aluminum and Copper Ions from Acid Mine Drainage Wastewater
(MDPI, 2020)
Adsorption technologies are a focus of interest for the removal of pollutants in water treatment systems. These removal methods offer several design, operation and efficiency advantages over other wastewater remediation ...
Feasibility of Ion-cyclotron Resonant Heating in the Solar Wind
(IOP Publishing, 2020)
Wave-particle interactions are believed to be one of the most important kinetic processes regulating the heating and acceleration of solar wind plasma. One possible explanation for the observed preferential heating of alpha ...
Copper ions stimulate polyphosphate degradation and phosphate efflux in Acidithiobacillus ferrooxidans
(AMER SOC MICROBIOLOGY, 2004-09)
For some bacteria and algae, it has been proposed that inorganic polyphosphates and transport of metal-phosphate complexes could participate in heavy metal tolerance. To test for this possibility in Acidithiobacillus ...
AtHMA1 is a thapsigargin-sensitive Ca2+/heavy metal pump
(AMER SOC BIOCHEMISTRY MOLECULAR BIOLOGY INC, 2008-04-11)
The Arabidopsis thaliana AtHMA1 protein is a member of the P-IB-ATPase family, which is implicated in heavy metal transport. However, sequence analysis reveals that AtHMA1 possesses a predicted stalk segment present in ...
Magnetic manganese dioxide as an amphoteric adsorbent for removal of harmful inorganic contaminants from water
(2010)
Manganese dioxide (δ-MnO2) with magnetic properties has been synthesized by precipitation of MnO2 in the presence of magnetite. The resulting material has a particle size distribution between 0.5 and 5 μm. Magnetization ...
Electromagnetic ion cyclotron waves with frequency below the proton gyrofrequency in large β|| multicomponent plasmas
(1989)
Electromagnetic ion cyclotron waves below the proton gyrofrequency in multicomponent plasmas have been extensively studied in recent years. However, it has recently been suggested that an often used analytical approach ...
