Cp*Rh(III)-catalyzed intermolecular C-C couplings between activated α-diazocarbonyl compounds and arenes bearing a range of azacyclic directing groups have been achieved. This catalytic alkylation reaction operates under mild conditions with good functional group tolerance.
A new technique for open quantum dynamics, combining reaction coordinate mappings and the polaron transform, allows efficient description of strong system-bath couplings, opening way novel applications in nanoscale transport thermodynamics.
This study offers an exclusive class of magnetic nanoparticles supported hyperbranched polyglycerol (MNP/HPG) that was functionalized with citric acid (MNP/HPG-CA) as a host immobilization of palladium nanoparticles. The MNP/HPG-CA/Pd catalyst was fully characterized using some different techniques such as thermogravimetric analysis (TGA), x-ray diffraction (XRD), transmission electron microsco...
In this paper, we review the roles of collective modes in nuclear reactions. We emphaize the strong couplings of various collective states with the monopole and quadrupole motions. In inelastic excitation, these couplings can be seen as an important source of anharmonicity in the multiphonon spectrum. In fusion reaction, the breathing and quadrupole motions strongly affects the oscillation of p...
The use of flow chemistry techniques has flourished over the past decade, with the field expanding to include the use of copper flow reactors in bench-top organic synthesis in recent years. These reactors are available in a variety of forms and possess a number of advantages over their batch reaction counterparts, in terms of both safety and yield. This review will highlight the current researc...
We show that the availability of longitudinally polarized electron beams at a 500GeV Linear Collider would allow, from an analysis of the reaction e+e− → W+W−, to set stringent bounds on the couplings of a Z ′ of the most general type. In addition, to some extent it would be possible to disentangle observable effects of the Z ′ from analogous ones due to competitor models with anomalous triline...
This paper describes the definition of maximum likelihood equivalent estimators of the Trilinear Gauge Couplings which include detector effects. The asymptotic properties of these estimators as well as their unbiasedness and efficiency when dealing with finite statistical samples are demonstrated by Monte Carlo experimentation, using simulated events corresponding to the reaction e+e− → qq̄lν at...
