Per- and polyfluoroalkyl substances (PFAS) are widely used in products such as non-stick coatings, waterproof fabrics, and firefighting foams due to their exceptional durability and chemical stability. However, their persistence in the environment and associated toxicity have rai ...
This master thesis explores strain-induced quantum emitters in hexagonal boron nitride (hBN) as novel optical nanoprobes for Förster resonance energy transfer (FRET)-based biosensors. These types of emitters could outperform conventionally used fluorophores due to their high bri ...

Optimization of the hot-filament chemical vapor deposition setup

Investigating the effect of filament placement and exploring the growth conditions for diamond synthesis

The hot-filament chemical vapor deposition (HF-CVD) method is widely used for the synthesis of thin films of polycrystalline diamond. These films are used in a broad range of applications, such as coating material on cutting tools, heat spreaders, and electrochemical sensors. HF- ...
Additive manufacturing technologies are widely gaining more attention, resulting in the development or modification of 3D-printing techniques and materials. At the same time, economical and ecological aspects force the industry to develop materials that are easier and quicker to ...
Boron-doped diamond (BDD) is a popular material for electrodes and it exhibits metal-like conductivity when a sufficient quantity of boron atoms is incorporated in the diamond lattice. BDD has distinct advantages over alternative electrode materials. It has diamond’s chemical sta ...
Boron-doped diamond (BDD) is an electrode material applied in high end advanced oxidation processes and electrochemical sensing. BDD has a low background current, is robust and has a high affinity for the production of oxidizing radicals. BDD shows better degradation rates comp ...

Effects of alkaline hydrothermal pre-treatment on sugars release and biogas composition

This study explored the interactions between alkaline hydrothermal pretreatment (AHPT) operational conditions temperature (°C), NaOH concentration (M) and residence time (min) on the compositional characteristics of the solid (SH) and liquid hydrolysate (LH) obtained from AHPT of ...

Carbon Dioxide Electroreduction on Gas Diffusion Electrodes

A study on electro-deposited copper catalysts

Rapid industrialization and use of carbon based fuels has caused a drastic increase in the atmospheric CO2 levels in the last few decades. The rising anthropogenic CO2 levels pose a significant threat to the environment as evidenced by the increase in the me ...
The exceptional material properties of bulk diamond like high stiffness, high thermal conductivity, wide optical transparency, chemical inertness and bio-compatibility make it the material of choice in many high-end applications. Most present-day diamond micro-devices are fabrica ...
Micro-/nanoimprint lithography is a high-throughput, high-resolution, and low-cost mass production fabrication process often used for creating microfluidic devices and optical components. In the imprint lithography process, a surface pattern of a stamp is replicated into a materi ...
Background: Soft-tissue grip is a challenge in minimally invasive surgery. Grasping instruments used in clinical practice require high pinch forces in order to generate sufficient grip for manipulating soft tissue without slipping.
In nature, several animals employ adh ...
Electrochemical sensing is a powerful tool for the rapid detection of (bio)molecules in fluids, and is frequently used in clinical analysis and diagnostics. Diamond is arguably the best electrode material for its robustness, wide potential window, very low background current, bi ...
