We present a comprehensive investigation of the charge-transfer (CT) effect in weakly interacting organic semiconductor mixtures. The donor-acceptor pair diindenoperylene (DIP) and N,N'-bis(2-ethylhexyl)-1,7-dicyanoperylene-3,4/9,10-bis(dicarboxyimide) (PDIR-CN2) has been chosen as a model system. A wide range of experimental methods was used in order to characterize the structural, optical, el...
We show an experimental and computational comparison between the resolution power, the contrast and the focal depth of a nonlinearly propagated diffraction-free beam and of other beams (a linear and a nonlinearly propagated Gaussian pulse): launching a nondiffractive Bessel pulse in a solution of Coumarine 120 in methanol creates a high contrast, 40 mm long, 10 microm width fluorescence channel...
Knowledge sharing is an important way for enterprise strategic alliance to participate in learning and dissemination of low-carbon knowledge. According the different size knowledge level participating enterprises, considering all kinds influencing factors willingness this paper constructs evolutionary game payment matrix obtains equilibrium solution. In view values absorption transformation abi...
Microsomal cytochrome b5 was 352-fold purified from potato tubers with a yield of 10.4%. To our knowledge, this is the first report relating the purification of higher-plant cytochrome b5. Its Mr (16 700) and absorption spectrum are similar to those of animal and yeast cytochrome b5.
In this paper we describe a case-based reasoning application developed for aiding engineers in the design of chemical absorption plants. Based on the notion of flow sheet, the paper describes how the application uses a highly structured representation of cases and similarity criteria based on chemical knowledge for designing solutions following an interactive case-based reasoning approach.
Knowledge of the monochromaticity of an x-ray source is increasingly important in fundamental experiments and critical applications. The bandwidth of an x-ray beam, selected from a synchrotron radiation spectrum for example, ultimately defines the limiting resolution of the synchrotron source. The development of x-ray technology through the use of characteristic line sources of fixed line shape...
We report on measurements of the light absorption efficiency of InSb nanowires. The absorbed 70 fs light pulse generates carriers, which equilibrate with the lattice via electron-phonon coupling. The increase in lattice temperature is manifested as a strain that can be measured with X-ray diffraction. The diffracted X-ray signal from the excited sample was measured using a streak camera. The am...
We propose a multiple beam illumination scheme to control the intensity of the light emitted by a thin luminescent layer. The experiment is designed to get as close as possible to the condition of Coherent Perfect Absorption (CPA) at a wavelength at which the absorption coefficient of the luminescent layer is low, and it is realized by externally acting on the phase difference between the incid...
The first application of atomic absorption spectra to chemical analysis was made as long ago as 1860 by Gustav Robert Kirchhoff (1824-87), who demonstrated the presence of various elements in the solar atmosphere. Together with Robert Wilhelm Bunsen (181199), he showed shortly afterwards that atomic spectra, whether in emission or absorption, could be the basis of a powerful method of chemical ...
