Optical frequency metrology of an iodine-stabilized He-Ne laser using the frequency comb of a quantum-interference-stabilized mode-locked laser

, 2007
We perform optical frequency metrology of an iodine-stabilized He-Ne laser using a mode-locked Ti: sapphire laser frequency comb that is stabilized using quantum interference of photocurrents in a semiconductor.

Inherited metabolic epilepsies–established diseases, new approaches

Epilepsia Open, EarlyView.
Abstract Inherited metabolic epilepsies (IMEs) represent the inherited metabolic disorders (IMDs) in which epilepsy is a prevailing component, often determining other neurodevelopmental outcomes associated with the disorder. The different metabolic pathways affected by individual IMEs are the basis of their rarity and heterogeneity.

The research progress in polyethylene oxide polymer electrolytes

FlexMat, EarlyView.
Polyethylene oxide (PEO) has become the mainstream matrix material for solid polymer electrolytes (SPEs) due to its excellent lithium salt complexation ability and processability. However, its high crystallinity results in low ionic conductivity at room temperature and difficulty in suppressing lithium dendrite growth, which significantly hinders the ...
