GSID: Q_ypQb9F5rwJ
J Turner, A Parisi - Teaching Science, 2008 - search.informit.org

A take-home experiment kit has been developed to reinforce the concepts in a first year physics course that both on and off campus students from a variety of educational backgrounds can successfully use. The kit is inexpensive and is...

On the Angular Dependence of the Vicinal Fluorine-Fluorine Coupling Constant in 1,2-Difluoroethane:  Deviation from a Karplus-like Shape.

Journal of chemical theory and computation

Provasi PF, Sauer SP.
PMID: 26633061

The angular dependence of the vicinal fluorine-fluorine coupling constant, (3)JFF, for 1,2-difluoroethane has been investigated with several polarization propagator methods. (3)JFF and its four Ramsey contributions were calculated using the random phase approximation (RPA), its multiconfigurational generalization, and both...

We describe the synthesis and the physical properties of polyaromatic hydrocarbons (PAHs) containing a phosphorus atom at the edge. In particular, the impact of the successive addition of aromatic rings on the electronic properties was investigated by experimental (UV/Vis...

Saffman-Taylor problem on a sphere.

Physical review. E, Statistical, nonlinear, and soft matter physics

PMID: 11308768
Phys Rev E Stat Nonlin Soft Matter Phys. 2001 Mar;63(3):036307. doi: 10.1103/PhysRevE.63.036307. Epub 2001 Feb 27.

The Saffman-Taylor problem addresses the morphological instability of an interface separating two immiscible, viscous fluids when they move in a narrow gap between two flat parallel plates (Hele-Shaw cell). In this work, we extend the classic Saffman-Taylor situation, by...

Reaction of mono-O-alkylated calix[4]arenes 2 with tri- to pentaethylene glycol ditosylates and K(2)CO(3) affords asymmetrical (1,2)-calix[4]crown ether derivatives 3 as the main product, along with minor amounts of calix[4]arene dimers 4 and mixed syn-distal di-O-alkylated calix[4]arenes 5. A reaction...

Shape recognition of alkylammonium ions by 1,3-bridged calix[5]arene crown-6 ethers: endo- vs exo-cavity complexation.

PMID: 11856007
J Org Chem. 2002 Feb 08;67(3):684-92. doi: 10.1021/jo015982k.

A series of tri-O-substituted 1,3-bridged calix[5]arene crown-6 ethers bearing alkyl, arylalkyl, alkoxyalkyl, and alkoxycarbonylmethyl residues at the lower rim and either (t)()Bu or H substituents at the upper rim have been synthesized. (1)H NMR studies have shown that p-tert-butylcalix[5]crowns,...

Stereochemical dependence of NMR geminal spin-spin coupling constants.
