Geometrical Monte Carlo model of liquid-phase sintering

Liquid-phase sintering (LPS) is an industrial process used to consolidate materials composed of two different kinds of metallic and/or ceramic powders. At constant temperature, the amount of the present liquid-phase is constant. However, the shape of parti ...

Peritectic solidification of Cu-Sn alloys

Frédéric Kohler

Many commercially important alloys such as Fe-C, Fe-Ni, Cu-Zn, Cu-Sn and Ti-Al exhibit peritectic transitions on solidification. In the two-solid phase region of peritectic metallic systems, a wide spectrum of microstructures has been revealed during direc ...

Fixed bed reactor for solid phase surface derivatization of superparamagnetic nanoparticles

Heinrich Hofmann, Jatuporn Salaklang, Alke Fink, Benedikt Steitz, Andrija Finka

The functionalization of nanoparticles is conditio sine qua non in studies of specific interaction with a biological target. Often, their biological functionality is achieved by covalent binding of bioactive molecules on a preexisting single surface coatin ...

Ultrasonic measurements in ice slurry generation by direct contact evaporation

Didier Albert Simon Vuarnoz

Important reductions of refrigerant amounts can be achieved by using secondary refrigeration fluids. Ice slurry is a two-phase fluid and thus, compared to single phase secondary refrigeration fluids, offers the advantage of the latent heat of fusion when t ...

Adaptive finite elements with high aspect ratio for the computation of coalescence using a phase-field model

Marco Picasso, Alain Jacot, Erik Burman

A multiphase-field model for the description of coalescence in a binary alloy is solved numerically using adaptive finite elements with high aspect ratio. The unknown of the multiphase-field model are the three phase fields (solid phase 1, solid phase 2, a ...

Modelling, mathematical and numerical study of a solutal phase-field model

Daniel Kessler

We investigate a thermodynamically consistent isothermal solutal phase-field mode1 describing the solidification of a binary alloy. The system is characterized by two variables: phase-field and concentration. The phase-field locally describes the phase sta ...

Bioactive biomaterials

Jeffrey Alan Hubbell

The most important advances in the field of biomaterials over the past few years have been in bioactive biomaterials. Materials have been developed to incorporate bioactivity through biological recognition, including incorporation of adhesion factors, poly ...

Conformational and orientational order and disorder in solid polytetrafluoroethylene

Ursula Röthlisberger

The low-pressure phase diagram of solid poly(tetrafluoroethylene) (PTFE/Teflon) has been investigated using const.-temp./const.-pressure mol.-dynamics techniques and a new all-atom potential model for fluorocarbons. The simulation was started in an ordered ...

Numerical Simulation of Macrosegregation : a Comparison between FVM and FEM Predictions and a Confrontation with Experiments

Michel Rappaz, Jacques Rappaz, Jean-Luc Desbiolles

Micro-macrosegregation calculations have been performed for a rectangular cavity containing either a Pb-48 wt pct Sn alloy or a Sn-5 wt pct Pb alloy. The numerical results calculated with a finite volume method (FVM) and a finite element method (FEM) are c ...

Temperature-Jump 2D NMR Spectroscopy in Crystalline Solids: A Technique for Correlating Molecular Reorientation across the Phase Boundaries of an Order-Disorder Lattice

Geoffrey Bodenhausen

The authors describe a two-dimensional high-resoln. solid-state NMR methodol. for correlating the dynamics of mol. rearrangements around the crit. points of equil. phase transitions in mol. solids. It combines the techniques of temp.-jump and two-dimension ...
