  • Effect of different types of aramid fibres on mechanical and thermal properties of nano-cellulose composites for vehicle applications

    Natural-fibre composites have been embraced by car manufacturers and suppliers for door panels, seat backs, headliners, package trays, dashboards, and interior parts. Natural fibres offer such benefits as reductions in weight, cost, and CO2. Eco-friendly green/composites were fabricated from nano-cellulose and bacterial cellulose (BC) reinforced by aramid fibres (AF). The purpose of this study is ...

  • Water analysis

    A complete tap water analysis includes the determination of the pH value, the alkalinity and the total water hardness. Both the pH measurement and the pH titration by means of a standard pH electrode suffer from several drawbacks. First, the response time of several minutes is too long and, above all, the stirring rate significantly influences the measured pH value. Unlike these standard pH ...

  • Microstructural study of thermally treated reactor pressure vessel steels using spectroscopic methods

    Positron annihilation spectroscopy (lifetime and Doppler broadening techniques), transmission Mössbauer spectroscopy, integral low-energy electron Mössbauer spectroscopy and transmission electron microscopy were applied to examine thermally treated reactor pressure vessel steels (RPV). The results of these methods obtained for different types of steels are discussed and correlated with hardness ...
