Hydrogen fuel cells are expected to be pivotal in the energetic transition towards renewable energy sources such as solar and wind power. However, their industrial scalability is severely hindered by the high cost and degradation rate of platinum catalysts, one of their key components. Addressing this…

This study investigates how two social and political developments, in the UK and Germany, impacted on the experiences of minorities and the attitudes of majorities vis-à-vis tolerance in those two countries. The results provide a thought-provoking picture of the views of minority and majority groups…

The study of orchid flowers, fruits, and inflorescences is crucial due to the remarkable diversity of orchid species and their unique adaptations to pollinators and seed dispersers. However, our understanding of the evolution and development of these organs within the orchid family remains limited.

This research delves into a region of space known as the interstellar medium (ISM), which is essentially the area between the stars filled with gas and dust.

The aim of this thesis is to develop and study a robust and adaptable scaffold for supramolecular polymer self-assembly in water.

How to facilitate the translation of science into innovation

This article researches the public perception of terrorist attacks by measuring the importance the public assigns to attributes of terrorist attacks.

The focus of the described research in this thesis is on the oxidative stress response (Nrf2 pathway). The aim of the research presented in this thesis is to obtain more information concerning microRNAs which are involved in the Nrf2 pathway, to determine and evaluate the application of microRNAs for…

On Tuesday 3 September 2024 Straton Papagianneas successfully defended a doctoral thesis and graduated.

What drives public agencies’ propensity to engage in more extensive practices and/or to initiate more far-reaching mechanisms of accountability than those mandated by law? In other words, what are the drivers of voluntary accountability?

This thesis studied in depth the energy use and CO2 emissions of the industrial sector in China.

Introduction to Medieval Europe 300–1500 provides a comprehensive survey of this complex and varied formative period of European history, covering themes as diverse as barbarian migrations, the impact of Christianisation, the formation of nations and states, the emergence of an expansionist commercial…

Reactions and reaction times in cognitive tasks.

In the Psychology Lab on Wheels, we conduct innovative research together with citizens. We drive our mobile lab to people all over the country helping to bridge the gap between science and society.

Solar energy is used by photosynthetic organisms to drive energy required cellular processes. Is absorbed by two groups of pigments, located in the LHCs.

Wetland plants are distinguished from plants of other terrestrial ecosystems by their adaptations to specific habitat stresses, including waterlogged and flooding and the subsequent abundance of phytotoxic compounds.

Has there been continuity or change in US counterterrorism policy since 9/11? What factors led to the continuity or change, and how do we classify any such continuity or change?

Solar energy harnessed by plants and algae has great potential to be converted into biofuels for future generations.

A large diversity of exoplanetary systems has been found, but it is still unclear what drives this diversity.

Mechanical forces are known to play an important role in bacterial colonies. In this dissertation, we study the self-organization at various stages of growing bacterial colonies, and focus on the mechanical effects of cell growth.

A key challenge in neuroscience is understanding how neurons in hundreds of interconnected brain regions integrate sensory inputs with previous expectations to initiate movements and make decisions.

The rapidly increasing commercial application of metallic nanoparticles within products will inevitably enhance the amount of NPs being released into soil.

The function of TLRs in innate immunity has aroused worldwide attention soon after its discovery. Because of the broad functions of TLR2 in innate immunity, the drive for the development of TLR2-targeted vaccines or therapeutic treatments has accelerated in the last decades.

Atherosclerosis is the most important underlying process that drives cardiovascular disease, and is characterized by an accumulation of cholesterol which triggers an inflammatory response in the vessel wall.

This thesis is concerned with the constitution of chiral responsive matrix assemblies that may undergo light-driven conformational changes and self-select vibrations to develop vibronic states for driving semi-classical coherent transfer with nearly 100% yield in a lossless NCAP process.

The master’s specialisation Evolutionary Biology at Leiden University investigates biology at all levels. The specialisation includes genomics, functional developmental genetics, paleobiology, behavioral biology and evolutionary ecology.

Organic amendments applied to agricultural fields can partially offset our carbon emissions to the atmosphere and improve the resilience of agriculture to the effects of climate change. Driving these benefits, however, are complex and poorly understood interactions between organic amendment properties,…
