Sports have been shown to influence and shape humans in many ways. However, how sports background influences decision-making in early stage entrepreneurial ventures has not been examined closely. Hence, this thesis addressed this gap and explored how sports backgrounds influence decision-making in early-stage ventures. More specifically, it delved into how experience as an elite team sports athlet

Responsible for roughly 40 % of global greenhouse gas emissions, energy usefor heating and cooling in the built environment constitutes a significant portionof annual total carbon emissions. The effort to decarbonise the heating andcooling sector necessitates efficient production, distribution and end use ofenergy. In this context, district heating and cooling is considered one of thecost-efficien

The power extracted by reverse electrodialysis (RED) is often limited by the high resistance of low concentration compartment. This work aims to address this issue by demonstrating a reverse electrodeionization (REDI) design that can facilitate the ion transport and alleviate so called spacer shadow effects. In total, three different stack designs were assembled by substituting the conventional sp

To meet climate targets, a global shift away from fossil fuels is essential. For sectors where electrification is impractical, it is crucial to find sustainable energy carriers. Renewable methanol is widely considered a promising fuel for powering heavy-duty applications like shipping, freight transport, agriculture, and industrial machines due to its various sustainable production methods. While

The only way to combat the depletion of resources and climate crisis is to reduceour dependence on fossil fuels. Renewable sources, such as wind and solar energy,are increasingly used to meet our ever-growing energy demands; however, they areintermittent. One promising solution to the power crisis in the world is fuel cells,which, unlike the combustion engine, can operate on renewable fuels such a

Nonlinear effects play a central role in photonics as they form the foundation for most of the device functionalities such as amplification and quantum state preparation and detection. Typically the nonlinear effects are weak and emerge only at high photon numbers with strong drive. Here we present an experimental study of a Josephson junction -based high-impedance resonator. We show that by takin

Converters of AC-DC nature are pivotal to supplying power in electronics, charging equipment, and renewable energy integration. A closed-loop Cuk converter with switched capacitor network and PID controller was proposed in this paper to mitigate the limitations of open circuit Cuk converter topology to ensure improved power factor from input along with low distortion in output, making it ideal for

With simultaneous policy and scholarly attention to the pollution crisis and the climate crisis, there is growing recognition that the two are intimately interconnected through the demand for oil, gas, and coal generated by synthetic materials. Drawing on theoretical resources from international political economy and beyond, we show how petrochemicals sit at the intersection of a number of the pri

A near-unity unselective absorption spectrum is desirable for high-performance photovoltaics. Nanowire (NW) arrays are promising candidates for efficient solar cells due to nanophotonic absorption resonances in the solar spectrum. The absorption spectra, however, display undesired dips between the resonance peaks. To achieve improved unselective broadband absorption, we propose to enclose distribu

Distributed solar photovoltaic systems are considered an important renewable energy source for meeting renewable energy targets and mitigating climate change. In several markets, emerging firms have established new business models to offer residential customers solar panel systems. In California, the third-party ownership business model has been successfully established during the last decade, and

As semiconducting nanowires have promising applications for materials science, nanoelectronics and photovoltaic devices, absolute control of their structure, morphology and composition is a prerequisite for their functionality. Nanowires, grown through the vapor-liquid-solid (VLS) method, exhibit a complex relationship between their liquid seed particle and what properties, such as the aforementio

A novel method is introduced in this study to consider flexibility taking into account both system design and operation strategy by using fuzzy logic. A stochastic optimization algorithm is introduced to optimize the system design and operation strategy of the energy system while considering the flexibility. GPU (Graphics Processing Unit)-accelerated computing is introduced to speed up the computa

Metal contamination of water bodies has attracted global attention owing to its environmental toxicity, abundance and persistence. Metals such as arsenic, cadmium and mercury are of greater concern since they are toxic even at low concentrations. Mercury is present at 1000 times lower concentrations than the other two metals, but still has a negative impact on the environment due to its high trans

Drop-in biofuels from forest by-products such as black liquor can help deliver deep reductions in transport greenhouse gas emissions by replacing fossil fuels in our vehicle fleet. Black liquor is produced at pulp mills that can increase their pulping capacity by upgrading some of it to drop-in biofuels but this is not well-studied. We evaluate the techno-economic and greenhouse gas performance of

This paper considers a sensor network where relay nodes cooperate in order to minimize the total energy consumption for the unicast transmission of a message from a single source to a single destination. We assume Destination Energy Accumulation, i.e., the destination can accumulate the energy of multiple copies of the message, each of which is too weak to be reliably decoded by itself, while the

Electronic commerce (E-commerce) is one of the issues that are expected to influence the various logistics and supply chain processes/operations including: production, packaging, warehousing, transportation, etc. Consequently, the environmental implications of E-commerce are of concern and interest. In this regard, there are some pilot studies, but they are unable to deliver conclusions or general
