Experiments Hardware and Methods

Three materials were extensively experimented with throughout the research here TiN, iridium and iridium oxide (IrOx). The solution used in the experiments to mimic the surrounding tissue in the application is phosphate buffered saline (PBS). Before continuing with the investigation of different electrode materials and their characteristics, the hardware and methods developed and used here are explained briefly. 

Users of chemometric methods should select their own software tools, on the one hand according to their desires and the tasks which are to be served, and on the other hand, according to personal experience, costs, and the hardware available. 

Because of the continued development of both computer hardware and modeling software, it will be increasingly possible to use even more sophisticated models and methods for modeling of zeolites and related systems. The need to reduce the complexity of a system as much as possible will diminish, meaning, in general, that models used in the future can produce results that should be more comparable to experiment than is possible at this moment.

Organophosphorus Chemistry series regularly lists new mass spectra in the Physical Methods chapter . With this in mind, an approach which considers fundamental aspects of organophosphorus ions (i.e. structure and reactivity) in the gas phase has been adopted. The gas-phase structure and reactivity of ions can be probed via several different techniques, including thermochemical measurements, kinetic energy release of metastable ions, collisional activation mass spectrometry, neutralization reionization mass spectrometry and ion-molecule reactions. An example is the molecule HCP (Table 1) its ionization potentiaP, proton affinity and the IR and rotational spectroscopy of the HCP ion " have all been determined in the gas phase. Another important tool for understanding the structure and reactivity of gas phase ions is ab initio molecular orbital theory. With advances in computational hardware and software, it is now possible to carry out high-level ab initio calculations on smaller systems. Indeed, the interplay between experiment and theory has fuelled many studies ... 

Product Service Experience Service experience (i.e., previous or current usage of the component) may be used to substantiate Development Assurance for previously developed hardware and for COTS components, where change is not introduced within this application. Note that in this context, this is direct product service history evidence, and not colloquial here say evidence. Data from non-airborne applications is not specifically excluded under RTCA/DO-254, although often these applications lack the necessary failure reporting data in order to be able to assess the product service experience. RTCA/DO-254 defines criteria on how to evaluate product service history. It should be noted that this is an onerous process, and many product service history cases do not have sufficient data in order to successfully evaluate product service history. Therefore, the architectural mitigation or advance verification methods must be used.
