High performance transition metal chalcogenides for water splitting catalyst prepared by anodic electrodeposition KU Leuven
The use of fossil energy is accompanied by large amounts of carbon dioxide emissions, which directly causes the greenhouse effect, and how to reduce carbon emissions is an urgent problem to be solved. Hydrogen is an ideal substitute for fossil fuel energy, and hydrogen production from water splitting is a viable method. However, the reaction has a high energy barrier and slow kinetic process, resulting in a great waste of electric energy. The ...
Contact to Semiconducting Transition Metal Dichalcogenides KU Leuven
The CMOS industry has made great strides in achieving enormous computational power by downscaling the metal oxide semiconductor field-effect transistors
(MOSFETs). Various technological innovations have been instrumental in achieving this transistor miniaturization. This scaling is reaching its limits
as short channel effects (SCE) significantly degrade the device performance. To enhance the electrostatic control and overcome SCE, ...
Synthesis of few layered transition metal dichalcogenides by ion implantation (SIMPLANT). KU Leuven
The SIMPLANT proposal addresses point 1 of the topic descriptions of the Graphene JTC areas, namely, "Synthesis and characterization of Layered Materials (LMs) beyond graphene". We propose a novel, large-scale method, based on ion implantation, for the controlled synthesis of few-layer transition metal dichalcogenides (TMDCs) of general formula MX2, where M is the transition metal and X the chalcogen element. Ion implantation is a highly ...
Electron, spin, and atom dynamics in excited transition metal oxide clusters KU Leuven
This research project deals with the study of electron, spin, and atom dynamics of excited transition metal oxide (TMO) clusters. The clusters will be driven out of equilibrium by short laser pulses and the position of the atoms, the electronic and magnetic states, as well as their dynamic interplay will be studied at any point in time thereafter. Hereto, different static and dynamic experimental techniques will be used such as magnetic ...

Mechanism of solvent extraction of transition metal ions by basic extractants KU Leuven
To date, solvent extraction is the best available technology for metal separation on industrial scale. Solvent extraction involves two immiscible liquid phases: an aqueous and an organic phase containing organic molecules (extractant). A metal distributes between the aqueous and the organic phase based on its affinity for the organic and aqueous phase. There exist three types of extractants: acidic, neutral and basic ones. The metal ...
Finite-Difference Time-Domain (FDTD) Modelling Algorithms for Transition Metal Dichalcogenides (TMDCs) in Nanoelectronic, Spintronic and Valleytronic Devices Ghent University
Two-dimensional (2D) materials attract a lot of interest for the development of novel nanoelectronic devices, owing to their monolayer nature, which allows for integration in planar devices. The most well-known example of such a material is graphene. Another class of 2D materials are transition metal dichalcogenides (TMDCs), which exhibit similar properties as graphene (superior carrier mobility, high cut-off frequency, etc), but are still ...
Mechanistic study of the activation of small molecules with transition metal active sites in zeolites KU Leuven
The activation of small molecules encompasses some of the most pressing challenges in catalysis. It relates to the upgrading of abundant molecules (O2, N2, CH4) for use in chemical industry, but also the remediation of malignant molecules (NOx, CO, greenhouse gases CO2, N2O, CH4). In this proposal I will use reactive oxygen species (ROS) in zeolites to achieve small molecule activation. Such zeolitic ROS are known on Cu and Fe exchanged ...
