Breakdown of the Wiedemann-Franz law in a unitary Fermi gas

We report on coupled heat and particle transport measurements through a quantum point contact (QPC) connecting two reservoirs of resonantly interacting, finite temperature Fermi gases. After heating one of them, we observe a particle current flowing from c ...

Combined Exergy Analysis and Energy Integration for the Optimization of Nitrogen Fertilizer Plants

François Maréchal, Daniel Alexander Florez Orrego, Shivom Sharma

Modern ammonia production plants are equipped with efficient energy integration networks able to recover an important fraction of the enthalpy of reaction released by the exothermic chemical systems. However, to fully supply the exergy demands of the highl ...

Thermo-economic optimization of an ORC driven heat pump based on small scale turbomachinery and comparison with absorption heat pumps

Jürg Alexander Schiffmann, Luis Carlos Mendoza Toledo, Violette Mounier

The current paper presents the thermo-economic optimization and comparison, through a multi-objective algorithm, between HP-ORC and the competing single effect absorption heat pump (SEAHP), with the aim to find the best trade-off between investment cost an ...

Meso-scale ceramic hotplates - A playground for high temperature microsystems

Paul Muralt, Thomas Maeder, Bo Jiang

This paper presents a mesa-scale low-temperature co-fired ceramic (LTCC) hotplate system. Using embedded thick-film platinum heaters, the hotplate has been able to operate at about 600 degrees C in a reliable manner, while its operating temperature can be ...

Controlled release from a mechanically-stimulated thermosensitive self-heating composite hydrogel

Dominique Pioletti, Harm-Anton Klok, Mohamadreza Nassajian Moghadam, Vitaliy Kolesov

Temperature has been extensively explored as a trigger to control the delivery of a payload from environment-sensitive polymers. The need for an external heat source only allows limited spatiotem- poral control over the delivery process. We propose a new a ...

A Thermoelectric Heat Engine with Ultracold Atoms

Jean-Philippe Brantut

Thermoelectric effects, such as the generation of a particle current by a temperature gradient, have their origin in a reversible coupling between heat and particle flows. These effects are fundamental probes for materials and have applications to cooling ...

Dissipation Can Act as a Mechanobiological Signal in Cartilage Differentiation

Dominique Pioletti, Arne Christian Vogel, Philippe Abdel Sayed

Knee cartilage is a soft tissue having viscoelastic properties. Under cyclic loadings, viscoelastic materials dissipate mechanical loadings through heat generation. In knee cartilage, this heat might not be convected because of the tissue avascularity, res ...

Cartilage self-heating contributes to chondrogenic expression

Dominique Pioletti, Arne Christian Vogel, Philippe Abdel Sayed, Mohamadreza Nassajian Moghadam

Articular cartilage is a soft tissue showing inelastic properties. Under cyclic loading, inelastic materials may dissipate mechanical energy into heat. In knee cartilage, due to an intrinsic reduced heat convection related to its avascularity, a local temp ...
