The research presented in this thesis explores the chemotherapeutic potential of metal-based compounds as chemotherapy agents, with an initial focus on the synthesis and DNA interaction studies of platinum and palladium compounds utilizing the [Pt(bapbpy)]2+ scaffold. The study identifies intercalation…

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.

Dissolution processes – next to aggregation processes - play an important role for fate prediction and environmental risk assessment of metal-based nanoparticles (MNPs). It is challenging to predict the kinetics of the dissolution process of MNPs in complex systems such as we can find in in vivo and…

Friday 30 January 2015 were the final presentations of the last course of the Minor Sustainable Development.

Studentenwelzijn is belangrijker dan ooit. Het staat hoog op de agenda van de Universiteit Leiden. De laatste tijd zijn er al veel nieuwe initiatieven ontstaan, waaronder de Wellbeing Week en POPCorner The Hague. Om al deze initiatieven te stroomlijnen en om nieuwe activiteiten voor het welzijn van…

Dit proefschrift gaat over de invloed van inductieprogramma’s op het welbevinden en de professionele ontwikkeling van beginnende docenten, en welke specifieke kenmerken van inductieprogramma’s daarvoor belangrijk zijn. Hiernaar is onderzoek gedaan met een interviewstudie en een grootschalige vragenl…

What physics controls the properties of quantum matter, such as how electrons flow inside high-temperature superconductors? This question has captivated the physics community and industry for decades, in part due to the great technological potential such materials have, but also because they have resisted…

Exploring the Meanings of Lands and Forests as an Avenue for Mutual Development of People and Nature in Ghana

Het is een belangrijk thema voor de universiteit en daarbuiten: studentenwelzijn. Al voor corona bleek uit onderzoek dat met name eenzaamheid en prestatiedruk voor grote problemen zorgen onder studenten, en met de pandemie is dit probleem enkel groter geworden. Inmiddels wordt er hard gewerkt om dit…

Tijdens de Student Well-Being Week organiseert de universiteit verschillende activiteiten waarbij studenten leren werken aan hun mentale en fysieke welzijn. Het doel van de week is het bespreekbaar maken en aankaarten van studentenwelzijn.

As leading cause of death worldwide, cancer is responsible for nearly 10 million deaths in 2020 according to World Health Organization (WHO). Cisplatin and its derivatives are commonly used chemotherapy agents for current cancer treatment in the clinics.

The global transition toward low-carbon energy systems and the rapid expansion of digital technologies, including artificial intelligence, are reshaping how modern societies produce, move, and process energy and information.

Seksueel misbruik van kinderen is een veelvoorkomend probleem: wereldwijd wordt ongeveer één op de vijf meisjes en één op de dertien jongens vóór hun achttiende jaar slachtoffer van een vorm van seksueel misbruik. Ondanks de hoge prevalentie zwijgen veel slachtoffers over deze ervaringen en wachten…

In surface science there is great effort to move from studying simple, flat model surfaces in vacuum to investigating more complex model catalysts in gas environments (in situ). This thesis gives three examples of such studies using microscopy and spectroscopy.

Cathodic corrosion is a relatively unknown phenomenon that can severely etch metallic electrodes at cathodic (negative) potentials.

To meet the rising demand for minerals driven by the global shift to clean energy technologies, ensuring responsible and resilient supply chains is critical. Minerals like cobalt, lithium, and nickel for batteries, neodymium and zinc for wind turbines, and indium for solar panels are essential.
