Multiphase transport and evaporative cooling in fuel cell gas diffusion layers

Sarah van Rooij

The use of evaporative cooling in the gas diffusion layer (GDL) of polymer electrolyte fuel cells has been proposed as a simple yet impactful solution to simultaneously provide the functionality of cell cooling, thanks to the dissipation of the latent heat ...

Transferability of the SRP32-vdW specific reaction parameter functional to CHD3 dissociation on Pt(110)-(2 × 1)

Rainer Beck, Ana Gutiérrez González, Helen Jane Chadwick

Stepped transition metal surfaces, including the reconstructed Pt(110)-(2 × 1) surface, can be used to model the effect of line defects on cata- lysts. We present a combined experimental and theoretical study of CHD3 dissociation on this surface. Theoretic ...

Key Energy and Technological Aspects of Three Innovative Concepts of District Energy Networks

François Maréchal, Daniel Favrat, Samuel Henchoz, Patrick Chatelan

Energy needs in urban areas are heterogeneous by their nature, spatial distribution and temperature level required. Three concepts of district energy networks that could provide the energy services efficiently to a city centre are compared. The focus is on ...

Quantum chemical studies of reactive species in water

Daniela Trogolo

In this thesis, quantum chemical methods have been applied to elucidate the thermodynamics and the kinetics of reactions involving reactive species in water. Due to their high reactivity in water, many transient species are difficult to study by experiment ...

Key energy and technological aspects of three innovative concepts of District energy networks

François Maréchal, Daniel Favrat, Samuel Henchoz, Patrick Chatelan

In urban areas, the use of thermal energy services is intensive and relatively heterogeneous by their nature, spatial distribution and temperature level required. In this study three concepts of district energy networks that could provide these services ve ...

Temperature Sensitivity of Nanochannel Electrical Conductance

Philippe Renaud, Arnaud Bertsch, Mojtaba Taghipoor

Electrical measurement is a widely used technique for the characterization of nanofluidic devices. The electrical conductivity of electrolytes is known to be dependent on temperature. However, the similarity of the temperature sensitivity of the electrical ...

Nanocalorimetric platform for accurate thermochemical studies in microliter volumes

Martinus Adela Maria Gijs, Thomas Lehnert, Raphaël Etienne Jean Trouillon, Rima Padovani

A straightforward and general way for monitoring chemical reactions is via their thermal signature. Such approach requires however an experimental setup with a high thermal stability that simultaneously allows time-resolved heat detection with high sensiti ...

Latency Correction of Error Potentials Between Different Experiments Reduces Calibration Time for Single-Trial Classification

José del Rocio Millán Ruiz, Ricardo Andres Chavarriaga Lozano, Inaki Asier Iturrate Gil

One fundamental limitation of EEG-based brain- computer interfaces is the time needed to calibrate the system prior to the detection of signals, due to the wide variety of issues affecting the EEG measurements. For event-related potentials (ERP), one of th ...

Application of single pan thermal analysis to Cu-Sn peritectic alloys

Michel Rappaz, Thomas Campanella

Single pan thermal analyses (SPTA) have been performed on Cu-14.5 wt.% Sn, Cu-21.3 wt.% Sri and Cu-26.8 wt.% Sit peritectic alloys. For this purpose, a SPTA assembly has been built and calibrated. As the latent heat is a function of temperature and composi ...

Thermochemical properties from ab initio calculations: pi- and sigma-free radicals of importance in soot formation: (C3H3)-C-center dot (propargyl), (C4H3)-C-center dot, (C13H9)-C-center dot (phenalenyl), (C6H5)-C-center dot (phenyl), (C10H7)-C-center dot (naphthyl), (C14H9)-C-center dot (anthryl), (C14H9)-C-center dot (phenanthryl), (C16H9)-C-center dot (pyrenyl), (C12H7)-C-center dot (acenaphthyl), and (C12H9)-C-center dot (biphenylyl)

Michel Rossi

The calculated difference in the standard heat of formation Delta Delta H-f degrees(298.15) of n- and i-C4H3 center dot free radicals is 37.9 kJ mol(-1) for G3MP2B3 and 45.0 kJ mol(-1) for CCSD(T)-CBS (W 1 U) calculations, which seems to preclude the direc ...

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

Robin Schäublin, Thomas La Grange

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 ...
