Sacrificial bonds and hidden length: Unraveling molecular mesostructures in tough materials

Sacrificial bonds and hidden length in structural molecules and composites have been found to greatly increase the fracture toughness of biomaterials by providing a reversible, molecular-scale energy-dissipation mechanism. This mechanism relies on the ener ...

Irradiation-induced phase transformation in undeformed and deformed NiTi shape memory thin films by high-energy ion beams

Irradiation-induced transformations in sputter-deposited Ti-rich NiTi thin films have been investigated with special attention given to the effects of prior deformation on the response of martensite phase. Irradiation at low fluence was carried out at room ...

How reliable are thermodynamic feasibility statements of biochemical pathways?

Urs von Stockar

The driving force for organo- or lithotrophic growth as well as for each step in the metabolic network is the Gibbs reaction energy. For each enzymic step it must be neg. Thermodn. contributes therefore to the in-silico description of living systems. It ma ...

Integrated LTCC micro-fluidic modules - an SMT flow sensor

Peter Ryser, Thomas Maeder, Yannick Sébastien Fournier, Raphael Willigens

This paper presents a thermal flow sensor based on the calorimetric principle realized by using low temperature co-fired ceramic (LTCC) technology, where the tapes and flow channel have been structured by laser machining. A standard configuration of a calo ...

Reaction calorimetry in supercritical carbon dioxide - methodology development

Thierry Meyer, Sophie Fortini, Frédéric Lavanchy

Reaction calorimetry is an efficient tool used to obtain kinetic, thermodn. and safety data. A reaction calorimeter, RC1e-HP350, developed in collaboration with Mettler-Toledo GmbH, allows investigating chem. reactions under supercrit. conditions. The main ...

A new tool for the study of polymerization under supercritical conditions - preliminary results

Thierry Meyer, Sophie Fortini, Philip Nising, Frédéric Lavanchy

Efficient stirring is needed to realize heat flow anal. with a thermally homogeneous medium. Because dispersion polymn. with supercrit. fluids can be destabilized under stirring, a preliminary target has been to find a compromise between synthesis and basi ...

Mechanical spectroscopy of decagonal Al-Cu-Fe-Cr quasicrystalline coatings

Robert Schaller, Nadine Baluc

Mechanical spectroscopy measurements were performed on decagonal quasicrystalline Al-Cu-Fe-Cr coatings of three different thicknesses deposited on a mild steel substrate. The mechanical loss spectra indicate that the internal friction is mostly caused by t ...

Structure and characterization of CI3+[Al{OC(CF3)3}4]-; Lewis acidities of CX3+ and BX3

Ines Raabe, Nils Trapp

Prepn. of the title compd. (I) from starting materials CI4 and AgAl{OC(CF3)3}4 was performed with the complete exclusion of light and with carefully purified diiodine-free CI4, since CI4 decomps. within minutes in soln. in light with formation of I2 ...

Investigation of particle-based and monolithic columns for cation exchange protein displacement chromatography using poly(diallyl-dimethylammonium chloride) as displacer

Jutta Christine Wandrey

The overall topic of the investigation was the sepn. of basic proteins by cation exchange displacement chromatog. For this purpose two principal column morphologies were compared for the sepn. of RNase A and a-chymotrypsinogen, two proteins found in the bo ...

Non-Isothermal Fusion Bonding in Semicrystalline Thermoplastics

Pierre-Etienne Bourban, John Christopher Plummer

The development of the interfacial bond strength as a function of bonding conditions has been investigated in two representative semicrystalline thermoplastics, isotactic polypropylene and polyamide 12. If one side of the interface is well above the meltin ...
