Organic semiconductors are emerging materials in the field of spintronics. Successful achievements include their use as a tunnel barrier in magnetoresistive tunnelling devices and as a medium for spin-polarized current in transport devices. In this paper, we give an overview of the basic concepts of spin transport in organic semiconductors and present the results obtained in the field, highlighting the open questions that have to be addressed in order to improve devices performance and reproducibility. The most challenging perspectives will be discussed and a possible evolution of organic spin devices featuring multi-functional operation is presented.

A new family of n-type dopants for organic semiconductors is reported. Changing the alkyl chain of these triazabicyclodecene (TBD) dopants alters their physical properties, including thermal stability, and influences their doping efficiency.

ABSTRACTTetrathiafulvalene and bis(ethylenedithio)tetrathiaful-valene radical-cation salts of the a-Keggin anion [PMo12O40] have been synthesized and characterized. They both are mixed-valence compounds and contain the paramagnetic anion [PMO12O40] 4-. The former contains irregular TTF ϱ+ chains isolated by the inorganic anions. From the IR spectrum a ϱ=+0.5 is suggested. The latter is two-dimensional, where BEDT-TTF molecules are ionised, ϱ=+0.5, and arranged in irregular chains. They show electrical conductivity typical of organic semiconductors.

Stimulation Of

Transient and very localized geophysical forces are hypothesized to be a major source of phenomena that have been traditionally labelled as haunts and poltergeists. They would be generated by increasing tectonic stresses and would display electromagnetic and gravitational characteristics. Materials would be influenced according to their physical properties. Dielectric materials would respond differently from conductors. Organic semiconductors, of which the human being is an important subcategory, would be affected as well. The conspicuous overlaps between (non-convulsive) complex partial epilepsy and many episodes of poltergeists and haunts are expected in light of the direct stimulation of the observer's brain by the transient, intense magnetic fields and the lability of temporal lobe structures. Implications and some general predictions for the distribution of these phenomena in time and space are discussed.

Ap Stars

The Ap stars are numerous - the photometric systems tool It would be very tedious to review in detail all that which is in the literature concerning the photometry of the Ap stars. In my opinion it is necessary to examine the problem of the photometric properties of the Ap stars by considering first of all the possibility of deriving some physical properties for the Ap stars, or of detecting new ones. My talk today is prepared in this spirit. The classification by means of photoelectric photometric systems is at the present time very well established for many systems, such as UBV, uvbyβ, Vilnius, Geneva and DDO systems. Details and methods of classification can be found in Golay (1974) or in the proceedings of the Albany Colloquium edited by Philip and Hayes (1975).

The bullet-shaped viruses are currently classified together on the basis of similarities in virion morphology and physical properties. Biologically and ecologically the member viruses are extremely diverse. In searching for further bases for making comparisons of these agents, the nature of host cell infection, both in vivo and in cultured cells, has been explored by thin-section electron microscopy.
