    Magnetic resonance in films and photodiodes based on poly-(phenyl-phenylene-vinylene) (1996)

    Notes: Films of poly-(2-phenyl-1,4-phenylene-vinylene) (PPPV) and photodiodes with PPPV as an active layer were studied by optically (ODMR) and electrically (EDMR) detected electron-spin resonance (ESR). Two different signals were observed in ODMR: enhancement of the photoluminescence (PL) at g=2.01 due to recombination of the photogenerated polarons (s=1/2), and a half-field enhancement signal, attributed to the fusion of triplet excitons. Both processes lead to the formation of singlet excitons. The spectral dependence of the s=1/2 signal follows the low energy part of the PL spectrum, indicating that delayed recombination of distant polarons is influenced by ESR, whereas the cw PL contains both prompt and delayed contributions. The linewidth and the intensity of the ODMR signal depend on the PL excitation intensity. Both effects are due to a decrease of the recombination lifetime of the polaron pairs at higher intensities. The relative decrease of the short-circuit photocurrent ISC through a PPPV photodiode by ESR saturation is due to recombination of nonthermalized, nongeminate excess charge polarons in the active layer of the device. This effect is at least two orders of magnitude stronger than the enhancement of total PL at the same temperature. This feature is found to be common for conjugated polymers investigated so far, and reflects the fact that the total photogenerated ISC is spin dependent, whereas ODMR selects only the nongeminate portion of recombining species in the sample. © 1996 American Institute of Physics.

    Einseitige Nierenrindennekrosen mit seitenverschiedenen intravasalen Fibrinpräcipitaten beim akuten Nierenversagen (1970)

    Description / Table of Contents: Zusammenfassung Bericht über 2 Patienten mit einseitigen Fibrinabscheidungen und Nierenrindennekrosen im Verlauf eines akuten Nierenversagens. Im ersten Fall trat bei einem 62jährigen Mann nach thrombotischem Verschluß eines Aneurysma der rechten Arteria poplitea mit Gangrän und nachfolgender Amputation des rechten Beines ein akutes Nierenversagen auf, als dessen morphologisches Substrat sich auf der rechten Seite ausgedehnte Fibrinpräcipitate in den Glomerulumcapillaren und kleinen Rindengefäßen sowie umfangreiche Nierenrindennekrosen fanden, während in der linken Niere Fibrinpräcipitate fehlten, hier nur eine osmotische Nephrose und wenige Nekrosen ganz vereinzelter Tubuluszellgruppen vorhanden waren. Es wird angenommen, daß die Läsion des rechten Beines der bestimmende Faktor für die schweren morphologischen Nierenveränderungen auf der rechten Seite war. Im zweiten Fall trat bei einem 65jährigen Mann mit rechtseitiger Nephrolithiasis und Hydronephrose bei Steinverschluß des Ureters eine Pyelonephritis auf dieser Seite auf, der sich unter dem Bilde eines Sanarelli-Shwartzman-Phänomens ein akutes Nierenversagen anschloß, an dessen Folgen der Patient nach 5 Tagen verstarb. Bei der Obduktion fanden sich in der linken, primär nicht geschädigten Niere sehr viel ausgedehntere Fibrinpräcipitate und Nierenrindennekrosen als in dem rechten, hydronephrotischen und pyelonephritisch veränderten Organ. Offenbar ist es hier in der Phase der Fibrinpräcipitation zu einer vermehrten Einschwemmung gerinnungsaktiver Substanzen in die kleinen Blutgefäße des gesunden Organs mit Verstopfung der Gefäßlichtungen gekommen, in dem so ausgedehntere Nekrosen als in der anderen Niere auftraten.
    Notes: Summary As demonstrated in two cases, disseminated intravascular precipitation of fibrin with renal cortical necrosis in acute renal failure may be limited to one kidney although the main renal arteries are symmetrical and patent. Case 1. A 62 year old man developed acute renal failure after amputation of the right leg which was gangrenous owing to thrombotic obliteration of an aneurysm in the right arteria poplitea. Clots of fibrin were fond generally in the glomerular capillaries and smaller vessels with extensive cortical necrosis of the right kidney, whereas in the left kidney there was only an osmotic nephrosis and necrosis of only a few tubular cells without intravascular clots of fibrin. The lesions of the right leg presumably were the determining factor for the severe renal lesions on the right side. Case 2. A 65 year old man with nephrolithiasis, hydronephrosis after occlusive ureterolithiasis and pyelonephritis on the right side developed acute renal failure in the course of a Sanarelli Shwartzman phenomenon. At autopsy many more fibrin clots and much more extensive cortical necrosis were found in the formerly unaffected right kidney than in the left hydronephrotic organ. Obviously more coagulative material was carried into the smaller renal vessels of the unaffected organ during fibrin precipitation; that led to more extensive necroses than in the contralateral kidney.

    Comparison of superconducting and electronic properties of σ-and A-15 phase Nb−Al (1977)

    Notes: Abstract For both, the σ-phase and the A-15 phase structure of Nb−Al binary alloys the superconducting properties were investigated in connection with measurements of normal state electronic properties like resistance and NMR-frequency and line width. The A-15 phase shows a transition temperature ofT c ≈17.5 K. The σ-phase shows only weak transitions at the same temperature which can be explained by A-15 inclusions in a non-superconducting σ-matrix. The Al27-Knight shift at room temperature is reduced from 0.162% for pure Al to (0.024±0.002)% and (0.026±0.0025)% for the A-15 and the σ-phase, respectively. The corresponding temperature coefficients differ in sign: positive for the A-15 and negative for the σ-phase; this may have a relation to the different superconducting properties. The NMR line width and the resistance show no different behaviour for the two phases. In general, the electronic properties seems to be less important for the occurance of superconductivity in the Nb−Al system than the lattice structures.

    Notes: Abstract The superconducting properties of A15-, σ-, and tetragonal phases of the system Nb−Ir were investigated. The alloys were prepared by sintering and arc melting. They were subjected to optical and scanning electron microscopy. The lattice parameters were determined by x-ray diffraction technique. Superconducting transition temperatures,T c , as well as upper critical fields,H c2, were measured inductively and resistively. TheT c -values of the σ-phase vary between 2.15 and 2.40 K whereas for the A15-phase they vary between 1.83 and 2.73 K. TheT c -value of the tetragonal phase is 3.81 K. The upper critical fields of the tetragonal and the A 15-phase are nearly the same (≈13 kG) and lower compared with that of the σ-phase (≈18 kG). Several theoretically predicted values ofH c2(0) are evaluated and compared with the experimental ones.

    Notes: Abstract The superconducting properties of A 15- and σ-phases of the system Nb−Pt were investigated. Alloys of compositions Nb3Pt, Nb2Pt, and Nb62Pt38 were prepared by arc melting and subjected to optical microscopic and x-ray analysis for structure determination. The transition temperatures were measured inductively as well as resistively. The temperature dependences of critical fields were measured up to 35 kG. The A 15-phase has aT c value of 8.97K and a zero temperature upper critical fieldH c2(0) of 100 kG as compared to aT c value of 2.14K and anH c2(0) value of 14kG for the σ-phase. A comparison with theoretical upper critical field values seems to indicate that a spin-orbit coupling mechanism is responsible for the higher value ofH c2(0) in the case of the A 15-phase alloy. The temperature dependent resistance up to 300 K is also measured and discussed for both the phases.
