Experimental study of the hydrodynamic and thermal performances of ventilated wall structures

The presence of a ventilated air gap behind the external cladding in a building envelope is known to have a tangible contribution to the overall performance of the wall assembly. In the present study, the hydrodynamic and thermal performances of ventilated ...

Development of High-Strength Aluminum Alloys for Additive Manufacturing

Marvin Lennard Schuster

Metal additive manufacturing (AM) offers the possibility to rapidly produce complex geometries that are not achievable with conventional manufacturing methods. The two most common technologies, Laser Powder Bed Fusion (LPBF) and Direct Metal Deposition (DM ...

Effect of post-heat treatment conditions on shape memory property in 4D printed Fe-17Mn-5Si-10Cr-4Ni shape memory alloy

Christian Leinenbach, Irene Ferretto

The influence of post-heat treatment on the microstructure and properties of 4D printed Fe-17Mn-5Si-10Cr-4Ni (wt. %) shape memory alloy (SMA) produced via a laser powder bed fusion process is investigated in this study. It is shown that heat-treatment temp ...

Mechanistic Study on Thermally Induced Lattice Stiffening of ZIF-8

Wendy Lee Queen, Kumar Varoon Agrawal, Pascal Alexander Schouwink, Jian Hao, Mehrdad Asgari, Deepu Joseph Babu, Qi Liu

The flexibility of the ZIF-8 aperture, which inhibits a molecular cutoff of 3.4 angstrom, can be reduced by rapid heat treatment to obtain CO2-selective membranes. However, the early stages of the structural, morphological, and chemical changes responsible ...

Influence of interfacial structural disorder and/or chemical interdiffusion on thermal boundary conductance for Ti/Si and Au/Si couples

Ludger Weber, Maïté Blank

This work aims at experimentally assessing the effect of structural disorder and/or chemical interdiffusion on thermal boundary conductance (TBC) at metal/dielectric interfaces. To this end, the TBC of Au/Si and Ti/Si interfaces was measured by time domain ...

Microfluidic and micromechanical in vivo studies of Caenorhabditis elegans

Roger Philippe Krenger

Caenorhabditis elegans is one of the most attractive model organisms in biomedical research for understanding human diseases and for drug testing at a whole-organism level, since many biological pathways and genes have been conserved between itself and hum ...

Neurotechnology-aided interventions for upper limb motor rehabilitation in severe chronic stroke

José del Rocio Millán Ruiz, Silvestro Micera, Friedhelm Christoph Hummel, Maximilian Jonas Wessel, Martina Coscia, John Donoghue

Upper limb motor deficits in severe stroke survivors often remain unresolved over extended time periods. Novel neurotechnologies have the potential to significantly support upper limb motor restoration in severely impaired stroke individuals. Here, we revi ...

Numerical Simulation of Solidification, Homogenization, and Precipitation in an Industrial Ni-Based Superalloy

Alain Jacot, Luc Rougier, Charles-André Gandin

A comprehensive simulation approach integrating solidification, homogenization, and precipitation during aging has been used to predict the formation of gamma/gamma' microstructures in the AM1 nickel-based superalloy. The particle size distribution of intr ...

Single trial prediction of self-paced reaching directions from EEG signals

José del Rocio Millán Ruiz, Ricardo Andres Chavarriaga Lozano, Eileen Lew Yi Lee

Early detection of movement intention could possibly minimize the delays in the activation of neuroprosthetic devices. As yet, single trial analysis using non-invasive approaches for understanding such movement preparation remains a challenging task. We st ...

Simulation de la formation des microstructures dans les superalliages à base de nickel de type AM1 durant la solidification et les traitements thermiques

Luc Rougier

Nickel base superalloys are used for the manufacturing of monocrystalline turbine blades, due to their outstanding mechanical properties at high temperature. The mechanical properties strongly depend on the presence of γ’ precipitates in the γ matrix. Impr ...

Reinforcement of CVD grown multi-walled carbon nanotubes by high temperature annealing

László Forró, Arnaud Magrez, Rita Smajda, Massimo Spina

We report on the increase of the Young's modulus (E) of chemical vapor deposition (CVD) grown multi-walled carbon nanotubes (MWNTs) upon high temperature heat treatment. The post heat-treatment at 2200-2800 degrees C in a controlled atmosphere results in a ...
