We introduce two new low temperature bonding technologies for the assembly of microstructured glass substrates for the realisation of microchannels for miniaturised chemical analysis applications. A first method consists of a proper cleaning of the two gla ...
Poly-quasicrystalline samples of an icosahedral Al-Cu-Fe alloy have been deformed in compression tests under constant-strain-rate conditions at temperatures ranging from room temperature up to 1020 K (m approximate to 1150 K, where T-m is the melting tempe ...
Some basic ideas of the heat transfer of ice slurries are discussed. The equations des-cribing a flow of a Bingham fluid through a tube with a heat flux over the boundary are presented. The theory shows that familiar Relations known in the field of heat ex ...

Bismuth-based layered compounds have been considered during the last years as interesting materials fur high temperature piezoelectric applications, due to their stability and wide thermal range of the ferroelectric activity. The high electrical conductivi ...
Superconducting power cables are one of the most promising energy applications of high-temperature superconductors, Losses in superconducting power cables are mainly due to AC, thermal and dielectric effects. The interplay of cable geometry, operating cond ...
We consider a nonlinear elliptic-parabolic system which stems from the modelling of heat induction processes in which a sinusoidal electromagnetic field is applied at the boundary of the inductor. The magnetic field satisfies an elliptic equation whereas t ...
Polycrystalline specimens of the ferritic-martensitic OPTIMAX A steel have been irradiated on the one hand with neutrons at 523 K to a dose of 2.5 dpa and with 590 MeV protons at ambient temperature and 523 K to doses of about 0.3 and 1 dpa on the other. C ...
The acoustic phonon dispersion curves of the hexagonal perovskite CsNiCl3 were measured at room temperature in the vicinity of the Gamma-point along the [0 0 1] and [1 1 0] directions. The derived velocity of sound values for the longitudinal and transvers ...
Fatigued state of the Pt-PZT-Pt system is studied by means of low-temperature conduction measurements. It is shown that the conduction in the temperature interval of 100-140 degrees K is determined by the cold field emission of electrons (tunneling conduct ...
Poly(dimethylsiloxane) copolymers containing a small fraction of carboxylic acid or Zn-carboxylate groups were prepared and compared regarding reversible gelation by hydrogen-bonding and ion-pair interaction. The polymers were synthesized by condensation o ...
