Phase equilibria in the Au-Cu-Ge ternary system, including the solid state phase relations at 450 degrees C as well as four vertical sections, were studied by means of scanning electron microscopy (SEM), electron probe microanalysis (EPMA), X-ray diffracti ...
The properties of the interface between solid and melt are key to solidification and melting, as the interfacial free energy introduces a kinetic barrier to phase transitions. This makes solidification happen below the melting temperature, in out-of-equili ...
The increasing availability of large metabolomics datasets enhances the need for computational methodologies that can organize the data in a way that can lead to the inference of meaningful relationships. Metabolic models comprising the entirety of reactio ...
The GP(I) zone formation during quench is simulated in an industrial Aluminumalloy AA7449 75mmthick plate by using a multi-class precipitation model. For this purpose, results of in situ SAXS experiments are reported. A methodology is presented that takes ...
We demonstrate experimentally that a part-per-million addition of Sn solutes in Al-Mg-Si alloys can inhibit natural aging and enhance artificial aging. The mechanism controlling the aging is argued to be vacancy diffusion, with solutes trapping vacancies a ...
Experiments were conducted using the X2 expansion tube at two conditions representative of flight velocities of 10.0 km/s and 12.2 km/s for a vehicle entry into Earth's atmosphere. Calibrated spectral measurements were made of radiating shock layers ac ...
Aqueous electrophilic reactions are broadly important in environmental chemistry, but the thermodynamic equilibrium constants, rate constants, and mechanisms describing these reactions are often difficult to determine by experiment. Here we report on our e ...
Experiments were conducted using the X2 expansion tube at two conditions representative of flight velocities of 10.0 and 12.2 km/s for a vehicle entry into Earth's atmosphere. Calibrated spectral measurements were made of radiating shock layers across and ...
We theoretically demonstrate a mechanism for bright soliton generation in spinor non-equilibrium Bose-Einstein condensates made of atoms or quasi-particles such as polaritons in semiconductor microcavities. We give analytical expressions for bright (half) ...
This study presents a design strategy for Al-Mg-Si alloys to control natural aging. Recently, trace addition of Sn was shown to suppress natural aging for up to two weeks, which was explained by the strong trapping of vacancies to Sn atoms. Here we explore ...
