Removal of Cd(II) ions from contaminated water by a new modified magnetic chitosan nano composite

Magnetic chitosan nanocomposites are one of the more recent advanced groups of adsorbents used to remove contaminants from waste water. In this research, N- Nicotinyl-N', N"-bis (Hexamethylenyl) phosphoric triamide (HE) was used as an additive to form a new nanocomposite with the structure of chitosan / 5% Fe3O4 Nps/10% HE resulting in the highly efficient removal of Cd(II...

Optode positional calibration in diffuse optical tomography.

Although diffuse optical tomography is a highly promising technique used to noninvasively image blood volume and oxygenation, the reconstructed data are sensitive to systemic difference between the forward model and the actual experimental conditions. In particular, small changes in optode location or in the optode-tissue coupling coefficient significantly degrade the quality of the reconstruct...

Force Field for Mg, Mn, Zn, and Cd Ions That Have Balanced Interactions with Nucleic Acids

Divalent metal ions are of fundamental importance to the function and folding of nucleic acids. Divalent metal ion−nucleic acid interactions are complex in nature and include both territorial and site specific binding. Commonly employed nonbonded divalent ion models, however, are often parametrized against bulk ion properties and are subsequently utilized in biomolecular simulations without con...

High-Precision Measurement of the Ground-State Hyperfine Splitting of Cd Ions for an Atomic Clock

We report a high-precision measurement of the ground-state hyperfine splitting of Cd ions. This result is vital for an atomic clock based on the cadmium ions to estimate the frequency uncertainty. OCIS codes: (120.3940) Metrology; (300.6520) Spectroscopy, trapped ion.
