We develop a simple tensorial contraction method to obtain analytical formula for X-ray resonant magnetic scattering. We apply the method considering first electric dipole-dipole and electric quadrupolequadrupole scattering in the isolated atom approximation and compare the results with previous works. Then we apply the method to derive phenomenological original formulas which account also for ...

[reaction: see text] Electrooptical sensors consisting of a conjugated chromophore undergoing a change in color and a redox-active moiety such as quinone fused to the chromophore were synthesized. Strong changes in colorimetric and electrochemical properties were observed in the presence of inorganic anions. A unique anion-specific response was observed for fluoride, pyrophosphate, and acetate....

We demonstrate and discuss a simple scheme that significantly enhances the detectivity of THz electro-optical sampling by introducing a sequence of Brewster windows that increases the ellipticity of the probe beam. By varying the window material or the number of Brewster windows, the enhancement factor can be adjusted; we demonstrate an enhancement factor of ≈20 with four ZnSe Brewster windows....

Construction of crystalline homo/heteroaggregation at micro/nanometer level from organic ?-conjugated systems is great importance because the controllable morphologies (i.e., size, shape, and dimension) could provide diverse optoelectronic properties for different applications in electrooptical devices. In this review, we summarize our recent progress self-assembly micro/nanostructures molecule...

-------------------------------------------------------------In the search for materials suitable for optical limiting applications to protect eyes and electrooptical sensors against laser radiation, fine carbon particles suspended in a liquid have been shown to possess highly desirable properties. This publication reports on the measurement of the threshold energy fluence for optical limiting ...

The development of new materials suitable for electrooptical studies has recently received a great deal of attention. One strategy deals with the preparation of zwitterionic molecules which are provided with a very high ground-state dipole moment [1, 2]. Michl and coworkers have presented in 1999 a tropylium ylide [12-C7H6-CB11H11] with a dipole moment of 11.25 D and a first hyperpolarizability...
