Tunable sieving of ions using graphene oxide membranes. [PDF]
Graphene oxide membranes show exceptional molecular permeation properties, with promise for many applications. However, their use in ion sieving and desalination technologies is limited by a permeation cutoff of ∼9 Å (ref.

Ion/ion chemistry of high-mass multiply charged ions [PDF]
Electrospray ionization has enabled the establishment of a new area of ion chemistry research based on the study of the reactions of high-mass multiply charged ions with ions of opposite polarity. The multiple-charging phenomenon associated with electrospray makes possible the generation of multiply charged reactant ions that yield charged products as ...

Polarized spectroscopy of Sm3+ ions in monoclinic KGd(WO4)2 crystals [PDF]
We report on a polarization-resolved spectroscopic study of Sm3+-doped monoclinic KGd(WO4)2 crystals. The transition probabilities for Sm3+ ions were calculated using a modified Judd-Ofelt theory.

An ion trap-ion mobility-time of flight mass spectrometer with three ion sources for ion/ion reactions [PDF]
This instrument combines the capabilities of ion/ion reactions with ion mobility (IM) and time-of-flight (TOF) measurements for conformation studies and top-down analysis of large biomolecules. Ubiquitin ions from either of two electrospray ionization (ESI) sources are stored in a three dimensional (3D) ion trap (IT) and reacted with negative ions from

Hydrated Ions: From Individual Ions to Ion Pairs to Ion Clusters
The structure of hydrated ions plays a central role in chemical and biological sciences. In the present paper, five ions, namely, Na(+), K(+), Mg(2+), Ca(2+) and Cl(-), are examined using molecular dynamics simulations. In addition to hydrated individual ions and ion pairs identified previously, hydrated ion clusters containing 3, 4, 5, or more ions ...

Distribution of Oil, Water, and Ions Near the Neutral Calcite Surface in the Presence of Low and High Salinity Water: Molecular Dynamics Simulation [PDF]
Low salinity water flooding has a significant impact on the recovery of carbonate reservoirs. In this paper, the molecular dynamics simulation was carried out to investigate the distribution of ions (Na+, Cl-, Ca2+, Mg2+, and SO42-), water, and oil ...
