High entropy alloys (HEAs) are new potential materials for hydrogen storage applications which could help with the transition towards sustainable energy sources. The rate of hydrogen kinetics is one of the material properties that is important for the storage and other hydrogen related applications. One of the limiting factors on the rate of...

Large-scale hydrogen storage is a crucial part of the energy transition. The usage of salt caverns has a great potential in this process, but there are open questions regarding the construction’s lifetime which need to be investigated prior to their implementation. In this work, potential construction steels were studied. The conditions in a...

Silicon heterojunction (SHJ) solar cells have exhibited efficiencies well above 25%. To further boost the efficiencies of c-Si-based solar cells, high-bandgap perovskite cells are stacked on top achieving a record efficiency of 29.52%. However, as most of the high-quality perovskite films are solution-processed, the front surface of the bottom...

In this work, mechanical stability and kinetics of hydrogen (de)sorption of thin Palladium films (100 nm) magnetron sputter deposited on a magnetron sputtered Titanium intermediate layer were studied. In particular of two film morphologies, an open voided columnar morphology and a compact columnar morphology, the substrate-induced stress and its...

The global production of steel in a year is in the range of several millions of tonnes due to its essential function in industries such as automotive, manufacturing, and construction among others. However, a major challenge faced by the steel industry in the development of new steel grades is the inability to predict surface behaviour, such as...

Surface compositions play a predominant role in the efficiency and lifetime of membranes and catalysts. The surface composition can change during operation due to segregation, thus controlling and predicting the surface composition is essential. Computational modelling can aid in predicting the alloy's stability, along with designing surface...

Environmental factors in the field cause partial shading of Cu(In,Ga)Se2 (CIGS) thin-film photovoltaic modules. Partial shading forces shaded cells into reverse bias leading to irreversible efficiency loss. The origin of the irreversible efficiency loss is the formation of defects in the shaded cell. The defects are going by the name of ’worm...

An exponential growth in CO2 concentration over the past few decades has led to an accelerated impact of climate change on planet earth. In a bid to curb these emissions, people across the globe are slowly transitioning towards renewable energy sources with battery technology aiding this growth. Given that battery technology is still in its...

This work investigates the enhancement of photocatalytic activity of titanium dioxide (TiO2) commercial particles by ultrathin silicon dioxide (SiO2) films deposited via atmospheric pressure atomic layer deposition (ALD) carried out in fluidized bed reactor (FBR). The ALD process enabled precise control for the growth of ultrathin film at sub...

A precise control for the growth of thin film powered by atmospheric pressure atomic layer deposition (ALD) carried out in fluidized bed reactor makes the ultrathin conformal coating of SiO2 on Degussa P25 TiO2 nanoparticles possible. At an operating temperature which can be lowered to room temperature (~27°C), the growth per cycle (GPC) smaller...

Palladium (Pd) metal membranes are used for the production and effective storage of high purity hydrogen. To overcome the crack and de-lamination of Pd membranes at room temperature during several hydrogen loading and de-loading cycles, a Titanium (Ti) of very small thickness of less than 10 nm is introduced as an intermediate layer between the...

The aim of this thesis is to explore the use of topology optimization in designing materials for heat flow manipulation. Specifically shielding, concentrating or even inverting the heat current was examined. The possibility to scale the problem from macro- to nano-dimensions by using topology optimization for nanoscale heat conduction was also...

Computational modeling offers the possibility to design alloys in a cheaper and faster way. A model for surface segregation for binary alloys in vacuum and by adsorption and absorption of gases was developed and applied. The proposed model was used in conjunction with the Miedema semi-empirical model for the calculation of enthalpies of solution...
