Voltammetry plays a crucial role in modern scientific research by offering valuable insights into the electrochemical properties of materials, with wide-ranging applications in fields such as materials science, energy storage, corrosion studies, and sensor development.

Galaxies in the local Universe fall into two main categories of spirals and ellipticals. In this Thesis, we explore the structural evolution of galaxies into this bimodal distribution.

In astronomy, the interpration of observations and measurements plays a crucial role: we rely purely and fundamentally on the information that reaches us as observers. And 80% of all matter in the universe is undetectable directly.

The expanding population and economic activity are driving up global energy consumption. Simultaneously, there is an urgent need to transition from fossil fuels to renewable sources to mitigate the climate crisis, primarily caused by fossil fuel combustion.

Mycorrhizas are symbiotic associations between soil fungi and most plant species.

This thesis examines the impacts and challenges of water use of electric power system. This thesis found that there are large differences in water use of electricity technologies, with hydropower and thermal power being two large water users.

One of the most important puzzles in modern astrophysics is the nature of dark matter.

Prostate cancer (PCa) is one of the most prevalent cancer in males.

The largest genus within the Phyllanthaceae family is a group called Phyllanthus L. Recent studies have shown, that Phyllanthus is paraphyletic with the genera Glochidion, Breynia and Synostemon nested within it.

A remarkable population of short period transiting rocky exoplanets with equilibrium temperatures on the order of 2,000 K has recently been discovered.

International trade has played a major role in defining the modern global economy. Trade, however, entangles the environmental pressures of economic sectors, giving the illusion of environmental improvements, while the opposite may be occurring.

It has been a long-standing mystery how complex biological structures emerge from such seemingly uncoordinated building blocks as cells and tissues, in the presence of only minimal environmental guidance.

A convolutional neural network (CNN) is a biologically inspired algorithm, highly capable at processing images and videos.

Plant diversity is essential for us and our planet as it sustains the stability of our ecosystems, provides vital materials and food to us and supports many ecosystem services.

How can prospective LCA be streamlined in a way that its practical application in research and technology development increases?

In this thesis, we developed new ways to use a technique called electroextraction (EE) to extract charged molecules from one liquid into another using an electric field.

A complex community of microbes develops in the infant gut shortly after birth. We call this community the infant gut microbiota. The microbiota influences the health of the infant, which makes the composition and function of the infant gut microbiota an important topic to study.

There is a need for alternative methods to replace, reduce and refine (3R) animal experimentation. Combining experimental data from high-throughput in vitro studies with in silico modeling is a promising approach to unravel the effect of chemicals on living cells and to gain a better understanding of…

Graphene nanoribbons (GNRs) are used as a current carrying substrate in investigation of current-induced forces in a low-temperature STM (chapter 2).

Where does the urge to collect come from? What are the explicit or underlying reasons for gathering large amount of objects?

Membrane fusion is a vital process in living organisms and is mediated by zipper-like proteins.

Global healthcare is on the verge of an antibiotic availability crisis as bacteria have evolved resistance to nearly all known antibacterials. Identifying new antibiotics that operate via novel modes-of-action is therefore of high priority.

This thesis is about the study of hydrocarbons via infrared spectroscopy.

Chinese materia medica (CMM), comprising a diverse array of natural substances from plants, animals, and minerals, has been integral to Traditional Chinese Medicine (TCM) throughout history. This study investigates the dynamic evolution of CMM, noting shifts in species for improved therapeutic effects…

Songbirds as vocal learners learn their songs and song preference from social tutors⁠. Tutor choice for both song and preference learning are important to characterize for understanding individual learning performance and cultural transmission of song⁠.
