Hydrated Ions: From Individual Ions to Ion Pairs to Ion Clusters
The Journal of Physical Chemistry B, 2015 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 ...

Alzheimer’s Disease, a Lipid Story: Involvement of Peroxisome Proliferator-Activated Receptor α
Cells, 2020 Alzheimer’s disease (AD) is the leading cause of dementia in the elderly. Mutations in genes encoding proteins involved in amyloid-β peptide (Aβ) production are responsible for inherited AD cases.

Effect of the doping level on the 2.8-µm laser performance of Er3+:CaF2 crystals [PDF]
EPJ Web of ConferencesThe effect of doping level (0.1-10 at.%) on mid-infrared laser performance of Er:CaF2 crystals was investigated. The Er:CaF2 laser delivered 1.17 W at 2798 nm with 35.8% slope efficiency and was tuned across 2690-2830 nm.

Dynamic ion-ion and water-ion interactions in ion channels
Biophysical Journal, 1992 The dynamic interactions among ions and water molecules in ion channels are treated based on an assumption that ions at binding sites can be knocked off by both transient entering ions and local water molecules. The theory, when applied to a single-site model K+ channel, provides solutions for super- and subsaturations, flux-ratio exponent (n') greater
