Even after fifty years since its introduction, the empirical Thornton’s structure zone diagram remains a valuable tool for predicting thin film microstructure. This diagram is essential for understanding the correlation between synthesis, composition, structure, and physical properties in emerging applications. In this work, we critically appraise this diagram by examining Sn─O thin films grown at
As continuous access to energy is necessary for survival, the level of energy stores has a strong effect on fitness and survival. Behaviors by which energy stores are acquired and built up are known as foraging, and this is a very common topic in animal behavior studies. It is especially important for flying organisms to finely tune the level of energy reserves they carry. While most animals will
Today energy supply is moving towards more renewable, which brings challenges to the power grid. Intermittent power is difficult to predict and cannot be regulated in the same way as conventional power. If the grid is not dimensioned to handle the power peaks, the intermittent power can cause overload on the grid. Overload causes larger losses, can damage electrical components in the grid and/or a
We use energy in almost every aspect of our lives. Yet, often, we do not know the source of electricity that powers our homes or heats our food. In this episode, we explore energy communities as a form of decentralised and democratic energy production. Community energy sees people coming together to take control of their energy needs, by finding alternative ways to organise and govern the energy sWe use energy in almost every aspect of our lives.

The aim of this project was to create a model of the stand-alone LAES for use in future work at Siemens Industrial Turbomachinery (SIT). The model was created in IPSEpro with components developed from the software's standard library of power plant components. Required fluid properties were obtained from the Refprop DLL. This was accessed through the development of a DLL, functioning as a link
Management of intermittent renewable energy sources (RES) such as wind and solar is a significant issue for countries with interconnected electricity markets. Increasing amounts of electricity from intermittent RES increases the variability of electricity supply, causing electricity prices to become highly sensitive weather conditions. Unpredictable prices have a negative effect on new infrastruct

Electric power grids have a limited capacity for safe and reliable transfer of power. Due to the ongoing large-scale expansion of variable renewable energy sources, such as wind and solar, there is a growing need for rapid gridcapacity increase.This thesis explores methods for improving and expanding grid capacity through control of converter-interfaced energy resources, including wind and solar pElectric power grids have a limited capacity for safe and reliable transfer of power.
