Presence of heavy metal ions in wastewater is an important public concern. Adsorption are commonly used technique to remove various pollutants, including the ions, from contaminated water sources. However, common methods for adsorption are not completely efficient at low ion concentrations and the adsorbent should be improved in order to reaching the acceptable levels of adsorption efficiency. ...

The relationship between mass and charge has been a crucial topic in mass spectrometry (MS) because the mass itself is typically evaluated based on the m/z ratio. Despite the fact that this measurement is indirect, a precise mass can be obtained from the m/z value with a high m/z resolution up to 105 for samples in the low mass and low charge region under 10,000 Da and 20 e, respectively. Howev...

The goal of ultra-relativistic heavy-ion collisions is to create new states of hadronic matter that are believed to have existed until a few tens of microseconds after the ’big bang’. These efforts were largely stimulated by lattice QCD predictions that hadronic matter at high energy density undergoes a phase transition to a plasma of deconfined quarks and gluons. At present the lattice calcula...

Simulations of charging and profile evolution during etching of high aspect ratio polysilicon gates in typical high-density plasmas containing heavy ions ~e.g., BCl3 , Cl2 !, predict a reduction in charging and notching when lighter ions ~e.g., He! are added. The reduction occurs because of the influence of the ion mass on the ratio R of the ion sheath transit time to the rf period, which deter...

background: industrial development has caused the release of various pollutants including heavy metals into the environment. these toxic compounds are extremely dangerous to living beings and the environment due to their non-biodegradability, severe toxicity, carcinogenicity, the ability to be accumulated in nature and the ability to contaminate groundwater and surface water. the aim of the pre...
