  text: In diesem Forschungsprojekt wurde ein Messverfahren zur Bestimmung akustischer
    Materialparameter von Polymeren im Ultraschallfrequenzbereich entwickelt. Das
    Verfahrens sollte, die üblichen standardisierten Prüfmethoden erweitern, die bislang
    primär im quasistatischen oder niederfrequenten Bereich eingesetzt wurden. Im
    Gegensatz zu bestehenden Verfahren wie dem Zeitstandversuch oder der Dynamisch
    Mechanischen Analyse (DMA) nach [DIN6721] sollte die neue Methode eine nicht-invasive
    Charakterisierung der (visko-)elastischen Materialparameter im Frequenzbereich
    von 0,75 MHz bis 2,5 MHz ermöglichen. Das entwickelte Ultraschallmesssystem arbeitet
    nach dem Puls Echo-Prinzip und kann eine räumlich segmentierte, ringförmige Anregung
    erzeugen. Die Bestimmung der frequenzabhängigen Materialparameter geschieht hierbei
    über ein inverses Verfahren. Die Ergebnisse des Projekts zeigen, dass die Segmentierung
    der Anregung, die Geometrie der Probe sowie das Puls-Echo-Messprinzip die Messergebnisse
    sowie die Sensitivität gegenüber Scherparametern wesentlich beeinflussen. Im Rahmen
    des Projektes wurde auch eine statistische Auswertung des Optimierungsverfahrens
    hinsichtlich transversal-isotroper Materialsymmetrie mit Rayleigh-Dämpfung durchgeführt.
    Die Ergebnisse zeigen, dass das entwickelte Verfahren gute Konvergenzeigenschaften
    aufweist und sich durch verbesserte Robustheit auszeichnet.

  text: This research project involved developing a measurement method to determine
    the acoustic material parameters of polymers within the ultrasonic frequency range.
    The aim of this method is to extend the range of standardised tests that operate
    in the quasi-static or low-frequency range. In contrast to existing methods such
    as the creep test or dynamic mechanical analysis according to [DIN6721], the developed
    method is capable of non-invasive characterisation of the (visco-)elastic material
    parameters in the frequency range of 0,75 MHz bis 2,5 MHz. The developed ultrasonic
    measurement setup utilises the pulse-echo principle and can generate a spatially
    segmented, ring-shaped excitation. The frequency-dependent material parameters
    are determined using an inverse method. The final results of the project show
    that the segmentation of the excitation, the geometry of the specimen and the
    pulse-echo measurement principle have a significant influence on the measurement
    results and the sensitivity to shear movements. As part of the project, a statistical
    evaluation of the optimisation process was also carried out with regard to transversely
    isotropic material symmetry with Rayleigh damping. The results show that the developed
    process has good convergence properties and is characterised by improved robustness.

  text: The controlled delivery of active pharmaceutical ingredients to the site of
    disease represents a major challenge in drug therapy. Particularly when drugs
    have to be transported across biological barriers, suitable drug delivery systems
    are of importance. In recent years responsive delivery systems have been developed
    which enable a controlled drug release depending on internal or external stimuli
    such as changes in pH, redox environment or light and temperature. In some studies
    delivery systems with reactivity against two different stimuli were established
    either to enhance the response by synergies of the stimuli or to broaden the window
    of possible trigger events. In the present review numerous exciting developments
    of pH-, light- and redox-cleavable polymers suitable for the preparation of smart
    delivery systems are described. The review discusses the different stimuli that
    can be used for a controlled drug release of polymer-based delivery systems. It
    puts a focus on the different polymers described for the preparation of stimuli-sensitive
    systems, their preparation techniques as well as their stimuli-responsive degradation.

  text: Polymer Laser Sintering (LS) is one of the most used Additive Manufacturing
    (AM) technologies for the tool-less production of polymer parts. The raw material
    is a polymer powder which is melted layerwise by the use of laser energy. Especially
    for the production of single parts, small series, individualized and complex structures,
    the technology is yet established in few branches. However, inhomogeneous and
    hardly controllable thermal effects during manufacturing limit the build reproducibility.
    The present work focuses on temperatures within so-called part cakes, their time
    dependency and their influence on process quality. Therefore, a temperature measurement
    system is implemented into a commercial laser sintering machine. Based on the
    experimental data a model to simulate heat transfer within part cakes is set up.
    Individual thermal histories during processing are successfully correlated with
    position dependent powder ageing effects. Another focus is on the analysis of
    a recycling optimized material. First results of correlations between thermal
    histories and part properties are shown in order to provide an outlook to further
    research. The data and knowledge gained through this work can be used to understand
    thermal effects in greater depth and to increase the process quality via optimizations.

  text: A large proportion of plastics today is compounded, which means the process
    from refining a raw material to the processable material. For this process compounding
    extruders are used which mostly involve tightly intermeshing, co-rotating twin
    screw extruders. These extruders consist of two closely spaced screws which rotate
    in the same direction and convey the raw material to the screw tip. These screws
    are surrounded by several barrel modules which heat or cool the material. As the
    whole design of the machine is modularly arranged the process behavior of a twin
    screw extruder depends for the main part on the arrangement of the screw and the
    barrel elements. Until today this arrangement and process optimization is conducted
    by experienced engineers and with the help of trial-and-error methods. Furthermore,
    theoretical models are used with which the behavior of the extruder is estimated.
    As these models are mostly very complex they are only made available with the
    realization in different software projects. One of the tools is called SIGMA.
    Within this paper SIGMA is introduced as a software to optimize a twin screw extruder.
    SIGMA supports the engineer already in the early stages of the extruder arrangement.
