Effects of Water Addition on a Catalytic Fluorination of Dienamine

Molecules, 2019
We investigate the effects of water addition on a highly stereocontrolled fluorination of dienamine generated by α-branched enals and 6′-hydroxy-9-amino-9-deoxy-epi-quinidine with N-fluorobenzenesulfonimide (NFSI) in the presence of Brø ...

Quantitative Approaches for the Determination of Volatile Organic Compounds (VOC) and Its Performance Assessment in Terms of Solvent Types and the Related Matrix Effects

Asian Journal of Atmospheric Environment, 2017
For the quantitative analysis of volatile organic compounds (VOC), the use of a proper solvent is crucial to reduce the chance of biased results or effect of interference either in direct analysis by a gas chromatograph (GC) or with thermal desorption ...

Microscopic mechanism for cold denaturation [PDF]

, 2007
We elucidate the mechanism of cold denaturation through constant-pressure simulations for a model of hydrophobic molecules in an explicit solvent. We find that the temperature dependence of the hydrophobic effect is the driving force/induces/facilitates ...

Pyrosol deposition of anatase TiO2 thin films starting from Ti(OiPr)4/acetylacetone solutions [PDF]

, 2007
TiO2 thin films were deposited on Si(100) and steel substrates by Pyrosol technique. The layer morphology depends on the concentration of titanium tetra-isopropoxide (TTIP) used as molecular precursor in solutions with acetylacetone (Acac).

Phase chirality and stereo-selective swelling of cholesteric elastomers [PDF]

, 2003
Cholesteric elastomers possess a macroscopic ``phase chirality'' as the director n rotates in a helical fashion along an optical axis $z$ and can be described by a chiral order parameter.

Structure and Dynamics of Solvated Polymers near a Silica Surface: On the Different Roles Played by Solvent [PDF]

, 2018
Whereas it is experimentally known that the inclusion of nanoparticles in hydrogels can lead to a mechanical reinforcement, a detailed molecular understanding of the adhesion mechanism is still lacking.
