Experiments on the intrinsic stress in immiscible Cu/W nanomultilayers (NMLs) show two unusual features: a compressive-to-tensile transition as a function of NML deposition conditions and extremely high interface stresses under both high- and low-pressure ...

Cesium-formamidinium lead iodide (CsxFA1-xPbI3) perovskites are a promising methylammonium-free alternative for efficient single-junction solar cells. However, they have not been fully explored by vapor-phase deposition techniques. Herein, a template-assis ...

Integrating unconventional HfO2-based ferroelectrics in thin film transistors (TFTs) has proven effective in enhancing performance by stabilizing negative capacitance (NC). This is achieved by incorporating the ferroelectric in series with a high-permittiv ...

Although important for atmospheric processes and gas-phase catalysis, very little is known about the hydration state of ions in the vapor phase. Here we study the evaporation energetics and kinetics of a chloride ion from liquid water by molecular dynamics ...

Tissue phantoms are materials designed to mimic the dielectric properties of biological tissues. This work proposes eco-friendly tissue phantoms of cartilage, cerebrospinal fluid and stomach in the frequency range between 0.4 and 6 GHz. For reaching this p ...

The chemistry of divalent lanthanides has generated increasing interest in the past years due to their redox properties and unique reaction pathways. Notably, molecular complexes of low-valent lanthanides have been shown to be suitable one-electron reducta ...

Hydrogels have emerged as promising materials for bioelectronic interfaces due to their tissue-like properties and high-water content. However, conventional hydrogels often suffer from poor electrical conductivity and mechanical stability, limiting their p ...

The goal of my PhD was the development of a new method for unselective surface labeling, not substrate-specific, that would give access to direct visualization of any surface interactions. In order to achieve this challenging goal, we wanted to develop a g ...

The production of single-layer polymer ribbons and sheets composed of fused porphyrin rings, named porphene, an analog to graphene, has been aimed over the years as a promising material for applications. Several attempts to polymerize porphyrin rings have ...

Microbially induced calcium carbonate (CaCO3) precipitation (MICP) is one of the major sustainable alternatives to the artificial cementation of granular media. MICP consists of injecting the soil with bacterial- and calcium-rich solutions sequentially to ...

Single-cell impedance flow cytometry (IFC) is a rapid, label-free diagnostic capable of resolving the dielectric properties of individual cells. Here, single-cell IFC is employed to investigate the effects of plasma-activated water (PAW) on E. coli. This d ...

Knudsen flow experiments and its interpretation in terms of adsorption/desorption kinetics as well as quantitative uptake on substrates of interest is presented together with the description of critical design parameters of the Knudsen Flow Reactor (KFR). ...

With the development of wide band-gap devices, Silicon Carbide (SiC) semiconductor devices in 10 kV–15 kV voltage class offer potentials in medium-voltage (MV) systems. To ensure reliable operation of these MV SiC devices, gate driver power supplies must m ...

In this thesis we present the design of two setups to study low-energy collisions between neutral species: an electron velocity map imaging for chemi-ionisation reactions and a merged electrostatic guide for polar molecules scattering. In the past few yea ...

Polycrystalline perovskite light-emitting diodes (PeLEDs) have shown great promise with high efficiency and easy processability. However, PeLEDs using single-cation polycrystalline perovskite emitters have demonstrated low efficiency due to defects within ...

Understanding and describing the dynamics of proteins is one of the major challenges in biology. Here, we use multifield variable-temperature NMR longitudinal relaxation (R-1) measurements to determine the hierarchical activation energies of motions of fou ...

The production of radioisotope beams at the ISOLDE (Isotope Separator OnLine DEvice) facility at CERN is achieved by irradiating target materials (e.g. uranium carbides and metal foils) with protons. The materials are usually operated at temperatures above ...

Supported Pd-based catalysts used in heterogeneously catalyzed liquid phase processes often undergo an activation step through reduction of the oxide phase or of the oxidic passivation layer prior to reaction. An oxidized Pd/Al2O3 catalyst was reduced by u ...

Vapor-based processes are particularly promising to deposit the perovskite thin film absorber of solar cells. These deposition methods are up-scalable, involve a controlled solvent-free environment, have the ability to conformally coat rough substrates, in ...

Recordings of the physiological history of cells provide insights into biological processes, yet obtaining such recordings is a challenge. To address this, we introduce a method to record transient cellular events for later analysis. We designed proteins t ...
