Ethylene glycol assisted intermolecular Pauson-Khand reaction [PDF]

open access: yes, 2017
The use of ethylene glycol as additive in the N-oxide-promoted intermolecular Pauson-Khand reaction (PKR) has been studied. The addition of 15% ethylene glycol to the reaction mixture consistently increased (from 20% up to 2-4-fold) the reaction ...

Opto-fluidic third order distributed feed-back dye laser [PDF]

open access: yes, 2006
This letter describes the design and operation of a polymer-based third order distributed feed-back (DFB) microfluidic dye laser. The device relies on light-confinement in a nano-structured polymer film where an array of nanofluidic channels is filled by
