Development of a laser-based heating system for in situ synchrotron-based X-ray tomographic microscopy

Michel Rappaz, Marco Stampanoni

Understanding the formation of materials at elevated temperatures is critical for determining their final properties. Synchrotron-based X-ray tomographic microscopy is an ideal technique for studying such processes because high spatial and temporal resolut ...

Experimental DSC-based method to determine glass transition temperature during curing of structural adhesives

Thomas Keller, Anastasios Vassilopoulos, Omar Moussa

A new DSC-based experimental method to efficiently establish the glass transition temperature, Tg, vs. curing degree, α, relationship for structural adhesives was developed. The method approaches the continuous Tg-α relationship with a trilinear curve esta ...

Thermocouple Thermal Inertia Effects on Impingement Heat Transfer Experiments Using the Transient Liquid Crystal Technique

Peter Ott, Alexandros Terzis, Bernhard Weigand

The transient liquid crystal technique is widely used for impingement heat transfer experiments. Additionally, due to the difficulty of producing pure temperature steps in the flow, many authors assumed the fluid temperature evolution as a series of step c ...

The important role of pressure in supercritical fluid process development revealed by reaction calorimetry

Thierry Meyer, Charalampos Mantelis

The technique of reaction calorimetry adapted for use with reactions in supercritical fluids was used to study some safety aspects of the free-radical dispersion polymerization of methyl methacrylate in scCO2. The reaction heat rate profile was found to ch ...

Order-disorder phase transition and stress-induced diffusion in Au-Cu

Daniele Mari, Robert Schaller, John Hennig

Isothermal mechanical spectroscopy by means of a forced torsion pendulum (measuring internal friction/mechanical loss) was used to study the interplay of long-range atomic order and stress-induced diffusion (Zener relaxation) in Au57%Cu43%. Our results sho ...
