Recyclable flame retardant phosphonated epoxy based thermosets enabled via a reactive approach
Véronique Michaud, Valentin Rougier
The development of reusable fire-safe polymers with a prolonged lifetime heralds the switch for a transition towards circular economy. In this framework, we report a novel phosphonated thermoset which is composed of networked phosphonate esters containing ...
ELSEVIER SCIENCE SA2023Multi-Scale Study of High-Temperature Latent Heat Storage With Metallic Phase Change Materials
Energy storage is a central issue in the green economy with half the global end energy usage being heat. Latent heat thermal energy storage (LHTES) provides an energy dense heat storage solution with a well-defined discharge temperature. Utilizing low-cost ...
EPFL2022Multi-configuration evaluation of a megajoule-scale high-temperature latent thermal test-bed
Sophia Haussener, Clemens Gregor Suter, Selmar Rudolf Binder, Nithin Mallya, Alberto Ortona, Maurizio Barbato
Thermal energy storage via latent heat provides an energy dense solution and, during discharge, a hot stream at a well-defined temperature. Utilizing metal phase change materials (PCMs) and high-temperature operation might enable fast (dis)charging and app ...
PERGAMON-ELSEVIER SCIENCE LTD2022Seasonality of density currents induced by differential cooling
Alfred Johny Wüest, Damien Bouffard, Hugo Nicolás Ulloa Sánchez, Tomy Doda
When lakes experience surface cooling, the shallow littoral region cools faster than the deep pelagic waters. The lateral density gradient resulting from this differential cooling can trigger a cold downslope density current that intrudes at the base of th ...
2022Conductive Heat Transfer in Partially Saturated Gas Diffusion Layers with Evaporative Cooling
Sophia Haussener, Felix N. Büchi, Mirco Magnini
Heat transport is an important, though often neglected function of gas diffusion layers (GDLs) of polymer electrolyte membrane fuel cells. Thermal conductivity is a key property, especially in partially water saturated GDLs and when the phase change of wat ...
2022Variation in Indoor Thermal Environmental Parameters in an Open Space Office
Dolaana Khovalyg, Verena Marie Barthelmes, Arnab Chatterjee
Building energy modelling is an indispensable component of today’s design method. However, as per research findings, real-life buildings could utilize almost twice the amount of their ideal energy performance. Thus, it is important to understand the variat ...
TU Delft2022Interspace and Vacancy Modulation: Promoting the Zinc Storage of an Alcohol-Based Organic-Inorganic Cathode in a Water-Organic Electrolyte
Expanding interspace and introducing vacancies are desired to promote the mobility of Zn ions and unlock the inactive sites of layered cathodes. However, this two-point modulation has not yet been achieved simultaneously in vanadium phosphate. Here, a stra ...
WILEY-V C H VERLAG GMBH2022Innovative Renewable Technology Integration for Nearly Zero-Energy Buildings within the Re-COGNITION Project
Alessandro Francesco Aldo Virtuani
With the 2010/31/EU directive, all new buildings shall be nearly zero-energy buildings (nZEB) from 2020 onward, with the aim of strongly reducing the energy consumption related to the building sector. To achieve this goal, it is not sufficient to focus on ...
MDPI2021Design optimization of the primary coil for induction heating
In this project we investigates a new design method for an optimized primary coil design for induction heating. Induction heating is used in many different application in the industry to heat up metallic materials. There could be many different reasons for ...
2021Hybrid Two-Phase Cooling Technology For Next-Generation Servers: Thermal Performance Analysis
John Richard Thome, Jackson Braz Marcinichen, Raffaele Luca Amalfi, Filippo Cataldo
This paper advances the work presented at ITHERM 2020 where a novel passive two-phase technology was introduced for more efficient cooling of datacenters compared to air-based cooling solutions (e.g. In-Room, In-Row, etc.). The proposed hybrid two-phase co ...
