    Antimony removal from dilute solutions using a restrained bed electrochemical reactor (1974)
    Springer
    Journal of applied electrochemistry 4 (1974), S. 69-73 
    Details
    ISSN: 1572-8838

    Topics: Chemistry and Pharmacology , Electrical Engineering, Measurement and Control Technology
    Notes: Abstract The electrochemical removal of Antimony from 1m sulphuric acid in a restrained bed reactor was studied in terms of current, flow velocity, bed depth, bead size and pressure drop. Current efficiencies are quoted as a function of current density and information is given so that they may be calculated in terms of the above variables. Experimentally-obtained limiting current densities are compared with calculated values, using empirical formulae from the literature.

    Mass-transport problems and some design concepts of electrochemical reactors (1974)
    Springer

    Notes: Abstract Electrochemical cells, designed to operate with reactants at low concentrations, require special provisions to be made for enhancement of mass transport of the reactants to the electrode surface. The different concepts for doing this in industrial or large-scale cells are reviewed. Examples are given of cells and processes in which these ideas have been used. A comprehensive literature survey of the quantitative relationships pertaining to the different configurations is given. The various cell designs are compared on a quantitative basis, usingi lim, and some advantages and disadvantages are discussed.

    Notes: Abstract Experimental data relating to the performance of a fast flow parallel plate electrochemical reactor are reported, using very dilute reactant solutions. The results are shown to conform to the Chilton-Colburn analogy. The significance of such reactors, in terms of both electrochemical processing and treatment of dilute aqueous effluents, is discussed.

    The efficiency of chlorine evolution in dilute brines on ruthenium dioxide electrodes (1972)

    Notes: Abstract The efficiency of chlorine evolution from dilute brines (0.5–0.1m) was studied on RuO2 and IrO2 coated Ti anodes at 20°C and 70°C. Efficiencies are generally much higher than on graphite electrodes. However at low current densities at 70°C the efficiency on RuO2 is considerably lower than on IrO2.

    Experimentelle Rekonstruktion der Orbita beim Schaf mit biodegradablen Implantaten (1998)

    Description / Table of Contents: Summary In a complex animal model in sheep, polydioxanone (PDS®) and polylactic membranes were used for the reconstruction of large orbital-wall defects. In a long-term experiment over 1 year, polylactic implants alone showed the best performance as compared with combinations involving autogenous bone grafts and titanium miniplate fixation. As soon as these polylactic implants are approved for human surgery, they will be used to solve the still challenging problem of anatomical reconstruction of large comminuted fractures of more than one orbital wall.
    Notes: Zusammenfassung In einem experimentellen Modell wurden biodegradierbare Membranen aus Polydioxanon (PDS ® ) resp. Polylaktat zur Rekonstruktion großer Orbitawanddefekte bei Schafen verwendet. Im Langzeitversuch über ein Jahr zeigten diejenigen Rekonstruktionen die besten Resultate, bei welchen ausschließlich biodegradierbare Implantate aus Polylaktat zur Anwendung kamen. Bei gleichzeitiger Verwendung von autologen Knochentransplantaten und Titan-Miniplatten-Osteosynthesen war die anatomische Form der rekonstruierten Orbita weniger zuverlässig gewährleistet. Es darf erwartet werden, dass die klinische Zulassung der Polylaktat-Implantate die chirurgische Wiederherstellung ausgedehnter Trümmerfrakturen mehrerer Orbitawände wesentlich erleichtern wird und zu vorhersehbaren, anatomischen Rekonstruktionen führt.

    Free expansion of a Bose–Einstein condensate from an Ioffe–Pritchard magnetic trap (1998)

    Notes: 5 rubidium-87 atoms released from an Ioffe–Pritchard magnetic trap is investigated experimentally. The expansion dynamics depend only on the trap frequencies, which are determined independently. The data are in good agreement with the expected expansion of a condensate, and are clearly distinct from the behaviour of a classical gas in the hydrodynamic regime.

    Controlled generation of single photons from a strongly coupled atom-cavity system (1999)
    Springer
    Applied physics 69 (1999), S. 373-377

    ISSN: 1432-0649
    Keywords: PACS: 32.80.Qk; 42.50.Ct; 42.65.Dr

    Notes: Abstract. We propose a new method for the generation of single photons. Our scheme will lead to the emission of one photon into a single mode of the radiation field in response to a trigger event. This photon is emitted from an atom strongly coupled to a high-finesse optical cavity, and the trigger is a classical light pulse. The device combines cavity-QED with an adiabatic transfer technique. We simulate this process numerically and show that it is possible to control the temporal behaviour of the photon emission probability by the shape and the detuning of the trigger pulse. An extension of the scheme with a reloading mechanism will allow one to emit a bit-stream of photons at a given rate.

    Rekombinationsverluste und IHR einfluss auf das Auflösungsvermögen von p-i-n-Zählern Sowie einige Messmethoden für τ, μ und die Homogenität (1966)

    Description / Table of Contents: Zusammenfassung Eine allgemeine Gleichung der Rekombinationsverluste in p-i-n-Detektoren wurde abgeleitet, die bei Kenntnis der Lebensdauer der Ladungsträger in der i-Schicht gestattet, diese Rekombinationsverluste zu berechnen. Für einzelne Fälle von Teilchenbahnen wurden vereinfachte Beziehungen gefunden. Das Impulsspektrum bei Querbestrahlung wurde theoretisch abgeleitet und experimentell nachgewiesen. Einige Meßmethoden der Lebensdauer und Beweglichkeit von Ladungsträgern in p-i-n-Detektoren wurden auf Grund der Spannungsabhängigkeit der Rekombinationsverluste und der Durchlaufzeit entwickelt. Erstaunlich sind die gefundenen niedrigen Werte der Lebensdauern unter 2 μs, die auf Rekombinationszentren in den Silizium-i-Schichten hinweisen. Die Rekombinationsverluste wurden auch zur Messung der Homogenität von p-i-n-Detektoren herangezogen. Es wurden die statistischen Schwankungen der Rekombinationsverluste, Oberflächenrekombination sowie Temperatur- und Spannungsabhängigkeit der Impulsspektren qualitativ untersucht und über einige experimentelle Ergebnisse berichtet.
    Notes: Abstract The general solution for the recombination losses was derivsd and some simpler equations for the different cases of irradiation were found. The theoretical spectrum of pulses for irradiation perpendicular to the field as a result of the general solution was proved experimentally. Some new methods of measuring the lifetime and mobility in p-i-n-type counters by means of the voltage dependence of the recombination losses and the transit time and new methods of measuring the detector homogeneity were developed. Different influences on the fluctuations of recombination losses and energy resolution, surface recombination, and the voltage and temperature dependence of the pulse spectra are treated in turn.
