  text: Two closely related FeII complexes with 2,6-bis(1-ethyl-1H-1,2,3-triazol-4yl)pyridine
    and 2,6-bis(1,2,3-triazol-5-ylidene)pyridine ligands are presented to gain new
    insights into the photophysics of bis(tridentate) iron(II) complexes. The [Fe(N^N^N)2]2+
    pseudoisomer sensitizes singlet oxygen through a MC state with nanosecond lifetime
    after MLCT excitation, while the bis(tridentate) [Fe(C^N^C)2]2+ pseudoisomer possesses
    a similar 3MLCT lifetime as the tris(bidentate) [Fe(C^C)2(N^N)]2+ complexes with
    four mesoionic carbenes.

  text: When performing measurements, the effects of the measurement system itself
    on the measured data generally must be eliminated. Consequently, those effects,
    i.e. the system’s dynamic behavior, need to be known. For the piezo-composite
    transducers in an ultrasonic transmission line, a model based approach is used
    to describe their dynamic behavior and take into account its dependence on the
    environment temperature and the acoustic impedance of the target medium. Temperature-dependent
    model parameters are presented, which are obtained by performing a multiplepart
    identification process on the transducer model, based on electrical impedance
    measurements [1]. The identification process uses an inverse approach for optimizing
    a subset of the model parameters. Additionally, algorithmic differentiation methods
    are used to determine accurate derivatives. In a final optimization step, impedance
    measurements taken at different temperatures are used to determine the temperature
    dependencies of the model parameters. These can then be used to assess the plausibility
    of the identification results. Additionally, the parameters can be expressed as
    polynomials in the temperature to take different operating conditions into account.

  text: For devices having non-linear contact, load plays a fundamental role. Variations
    in the characteristics of the load cause change in eigenfrequency and amplitude
    of the vibration. In most technical applications, this unwanted behaviour is cancelled
    by the use of control algorithms. However, multiple applications, like bond quality
    monitoring or chemical and pressure sensors, have found that the load may be characterised
    by interpreting the change in characteristics of a resonant vibrating device used
    as a sensor. Surgical resection of tumours is a very difficult task. After localising
    the tumour by the use of imaging techniques, the resection demands the surgeon
    to decide where and what to resect based on visual and tactile differentiation
    of tumour and healthy tissue. Exactness of this process could be enhanced if we
    can provide the surgeon with a device capable of evaluating mechanical characteristics
    of the tissue much more accurately than the surgeon himself can do. As the mechanical
    characteristics of tumour and healthy tissue differ but slightly, the task is
    to design a system with high sensitivity. Therefore, we have developed a resonant
    actuator-sensor that allows the differentiation among distinct media that have
    similar mechanical characteristics to tumour and healthy tissue using a piezoelectric
    bimorph. The design is based on the detection and evaluation of frequency shift
    and amplitude variation of the fundamental and higher harmonics using one layer
    for the resonant excitation of vibration and the other one as the sensing element.
