Study of the interfacial mechanical degradation in all-solid-state lithium batteries Vrije Universiteit Brussel

Annick Hubin
Materials and Chemistry, Faculty of Engineering
Lithium-ion batteries have become a key technology in our everyday lives, and great interest has grown during the past decade towards new materials and new configurations of the cells. Solid state lithium batteries (SSBs) allow having higher energy density without compromising power and capacity, while assuring high safety at variable temperatures and good cycle stability. However during the charge and discharge of these batteries, there are ...

On-demand Interfacial Coverage and Composition using Double Emulsion Templating KU Leuven

Paula Moldenaers, Jan Vermant
Soft Matter, Rheology and Technology Section

Emulsions are dispersions of an immiscible liquid into another liquid. We encounter them on daily basis, such as in food and personal care products. However, emulsions are thermodynamically unstable due to the high cost of the interface between the droplets and matrix fluid. For this reason, emulsions tend to coarsen over time by morphological processes such as coalescence and Ostwald ripening to reduce their interfacial energy. Therefore, ...

Local probing of interfacial coupling in correlated electron systems. KU Leuven

Kristiaan Temst
Quantum Solid State Physics (QSP), Nuclear and Radiation Physics
This research proposal focuses on thin-film correlated electron systems in which layers with different functionalities (ferromagnet, antiferromagnet, superconductor) are confronted with each other at their mutual interface. The intimate contact between two dissimilar layers leads, in general, to a proximity effect that influences the intrinsic properties of the constituent layers. In some cases the proximity effect can have a quite drastic ...

Utilizing interfacial impedance- and heat-transfer phenomena in advanced monitoring- and switching devices KU Leuven

Patrick Wagner
Soft Matter and Biophysics

Electrochemical impedance spectroscopy (EIS) is an established technique for probing the conductive and dielectric properties of matter in wide frequency ranges. Applications are numerous and cover the determination of salinity of sea water equally well as the detection of neurotransmitters and proteins in food- and blood samples. The applicants have found a ‘thermal counterpart’ to impedance spectroscopy in 2012 in which the electrical ...

Membranes synthesized via interfacial polymerization using 'new chemistry' monomers. KU Leuven

Ivo Vankelecom
Centre for Surface Chemistry and Catalysis

Membrane applications have gained an important place in separation processes and have been gradually combined with or have been substituting more traditional, industrial separation processes, such as distillation, adsorption and extraction. The majority of today’s industrial membranes for wastewater treatment and/or desalination are synthesized via interfacial polymerization, a technique which enables the synthesis of thin, dense top-layers ...

Mineral filler modification for improved material interfacial interactions KU Leuven

Veerle Vandeginste
Sustainable Materials Processing and Recycling (SeMPeR)
The exponential increase in the use of plastics is a result of their lightweight yet strong, tough and durable material properties. However, they have caused one of the greatest environmental challenges ever. Biodegradable plastics can offer a solution, but their material properties still need to be improved for specific applications, and this can be achieved by the use of mineral particle fillers (and fibres) in polymer composites. In this ...

Controlling the Dynamics of Liquid Interface KU Leuven

Jan Vermant
Soft Matter, Rheology and Technology Section
The main focus of the research described in this thesis is the development and analysis of interfacial rheometers. This development involves improvement of the data interpretation of existing interfacial rheometers,as well as the design and experimental validation of some novel approaches. Interfacial rheometry is classified based on the kinematics of the applied deformation into shear, extensional and dilatational rheology. This work ...

Unravelling two-phase expansion by experimental research on optical accessible volumetric machines Ghent University

Steven Lecompte
Department of Electromechanical, Systems and Metal Engineering

Two-phase expansion is seen in various applications and in many cases, it allows increasing the overall efficiency of the system. For example organic Rankine cycles (ORC), a mature technology to convert low temperature heat to electricity, can benefit from this. The modified cycle, also called a Trilateral cycle (TLC), can boost the power output up to 30%. The main challenge however is the development of high efficiency expanders that can ...

Modelling of two-phase expansion in volumetric expanders based on in situ flow characterization. Ghent University

Michel De Paepe
Department of Electronics and information systems, Department of Electromechanical, Systems and Metal Engineering, Department of Flow, heat and combustion mechanics

In the last decade, the organic Rankine cycle (ORC) has become a mature technology to convert

low temperature heat to electricity. However these ORCs are all of the subcritical type. Yet, studies

in scientific literature and our own research clearly shows the potential for increased performance

with alternative cycle architectures. The trilateral cycle (TLC) is one of the most promising

modifications and can boost the ...
