Piezoelectric ultrasonic motors are superior to electromagnetic micro motors, because their efficiency remains theoretically constant during miniaturization. However, the still relatively recent technology has a considerable unexploited optimisation potent ...
This thesis presents a methodology to analyse the integration of heat recovery energy conversion technologies and biorefinery concepts in existing pulp and paper facilities. By using innovative process integration techniques and thermo-economic optimisatio ...
Mixed ionic–electronic conducting La0:5Sr0:5 Fe1 xBxO3 δ (B: Al, Cr, Zr, Ga, Ti, Sn, Ta, V, Mg, and In with x=0, 0.1, 0.2) perovskite materials were produced via solid-state synthesis. In order to study the effect of Bsite substitution on the expansion beh ...
The behavior of a pile subjected to thermo-mechanical loadings was studied in situ with the aim of quantifying the thermal influence on the bearing capacity of heat exchanger piles. A pile situated in a building under construction was equipped with a chann ...
Multistage hydraulic systems and methods for converting the potential energy of a pressurized gas, particularly air, into mechanical work operating in motor, and for producing compressed gas from the mechanical work of the rotating shaft (A1.1 ) when rotat ...
Mixed ionic electronic conducting perovskite materials have been receiving considerable attention for the application of oxygen separation membranes. These membranes have potential to be integrated in industrial processes that require pure oxygen and to pr ...
The reliable prediction of pressure drop in two-phase flow is an important prerequisite to accurate optimization of thermal systems. Because of the complexity of these types of flow, empirical or semiempirical relationships are only of limited reliability ...

Using petrol as a main source of energy, during the 20th century, has caused considerable amounts of damage among which are atmospheric pollution and global warming. At the same time, many geologists and economists expect that the discovery rate of new pet ...
