Metal-based thermocompression bonding enables the creation of hermetic seals formed at relatively low processing temperatures and occupying a small portion of the device area. In the current study we have investigated the application of scanning acoustic microscopy (SAM) for assessing the quality of...
The alloy systems Al–Cu–Mg (2xxx) and Al–Zn–Mg (7xxx) are hardened by metastable nano-precipitates formed during heat treatment. The precipitate phases of the two systems are very different: 2xxx alloys have GPB-zones and S phases, which are needle-shaped, and have their main growth and coherency...
Large-scale CO2 injection problems have revived the interest in simple models, like percolation and vertically-averaged models, for simulating fluid flow in reservoirs and aquifers. A series of such models have been collected and implemented together with standard reservoir simulation capabilities...
The Au(III) complex Au(OAcF)2(tpy) (1, OAcF = OCOCF3; tpy = 2-p-tolylpyridine) undergoes reversible dissociation of the OAcF ligand trans to C, as seen by 19F NMR. In dichloromethane or trifluoroacetic acid (TFA), the reaction between 1 and ethylene produces Au(OAcF)(CH2CH2OAcF)(tpy) (2). The...
The customer journey approach is increasingly being taken up by practitioners and researchers to support the design and management of services. As part of this approach, customers and internal resources are often involved as contributors of input in design and management processes. In the current...
The oxygen nonstoichiometry in the misfit calcium cobaltite (Ca2CoO3)0.62(CoO2) has been studied experimentally and by density functional theory (DFT) calculations. The standard oxidation enthalpy ΔH0Ox of oxygen deficient (Ca2CoO3)0.62(CoO2) was measured directly using simultaneous thermogravimetry...
Optimal design and operation of a planned full-scale UASB reactor at a dairy farm are determined using optimization algorithms based on steady state simulations of a dynamic AD process model combined with models of the reactor temperature and heat exchanger temperatures based on energy balances...
