Development & demonstration of low environmental impact innovation and optimization practices in pharma production.

What performance criteria does a new technology have to fulfill in order to be added to the list of future energy options and what constraints exist in terms of broad market penetration?

The transition to electric vehicles (EVs) reduces vehicle emissions to combat climate change. EVs raise concerns regarding the production of lithium-ion batteries and related emissions; while batteries can also provide energy storage services for the electricity system.

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…

This PhD-thesis analyses the relationship between the parties’ choices in the CPB Netherlands Bureau for Economic Policy Analysis’ assessments of the election manifestos and coalition agreements over the period 1986-2017, and tries to explain this relationship.

Material circularity and energy efficiency are highly relevant and intertwined issues for the transition towards a carbon-neutral and circular built environment. In the Netherlands, the building sector has been rendered a priority towards a circular and low-carbon society.

What are the environmental trade-offs for SMEs considering moving from monoculture aquaculture practice towards IMTA? What are the environmental trade-offs comparing IMTA species with their conventional monoculture alternatives?

‘In Hong Kong, the elderly found our popular nature routes boring, so they now cycle our action-packed routes through New York.’ What once started as an assignment for the Master Programme Media Technology, has grown into the international market leader in the field of virtual reality exercises for…

As part of the NEXUS1492 project, this project will use ancient DNA techniques to shed new light on the demographic and health history of the Caribbean and the impact of European colonization on indigenous communities in the region.

Freshwater biodiversity has been threatened by eutrophication due to excessive nutrients in the environment. Releasing the freshwater species from such pressures requires efforts from industry and manufacturers to avoid emissions to vulnerable and high-risk regions.

Meet Thomas King, alumnus BA International Studies: ‘I’m currently living in London which is a really amazing experience! I’m a British citizen and I moved to the Netherlands to study BA International Studies back in 2017. I had the best three years ever living in The Hague and studying at Leiden.’

What are the life-cycle environmental impacts and risks to human health and ecosystems of a III-V/Si PV system? How can these be expected to change when the system is deployed at industrial scale? What are the most favourable recycling scenarios?

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

Consequences for sediment stability and seston trapping

Mattias Brand defended his thesis on 10 April 2019

The life cycle of comets near the star Beta Pictoris is similar to that of comets in our own solar system. This is the conclusion of a team of astronomers from the Netherlands, France and Brazil. It seems that, just like in our own solar system, there are fewer comets as the star gets older. The researchers,…

A framework for prospective/ex-ante life cycle assessment (LCA) and ecological risk assessment (ERA) of emerging technologies is developed and applied to a case study of III-V/silicon photovoltaic panels.

Just like the professional riders from the Jumbo-Visma team, amateur cyclists will soon be able to analyse and improve their performance. Leiden data scientists working with the cycling team are making their smart data model available so that every serious cyclist can keep track of their fitness.

With a headwind of 80 kilometres per hour, pouring rain and freezing temperatures, Jurjun van der Velde cycles down the Oosterscheldekering. On his traditional Dutch bike with back pedal brake, he is the second PhD student from the faculty to win the title.

Het is een wijdverbreid idee dat (post-)middeleeuwse steden een sterfteoverschot hadden en zij slechts in leven konden blijven door de toestroom van migranten; een fenomeen dat bekend staat als het ‘urban graveyard’-effect. Over details valt te twisten, maar duidelijk is dat de stad en de dood dichter…

Een scheepswrak, zijn bemanning en het leven in de 18de eeuw

Leiden bachelor students analyse data EC soccer Students are now familiar with something sports journalists already knew: summer holidays can be a time of hard labour. Everybody else is lying on the beach, but for you, it is the busiest time of the year. Leiden bachelor students collected the data…

Inaugural lecture

This project investigates how the first generation of Dutch printed books (the incunabula, 1473-1501) affected late medieval spirituality, religious practice and visual culture in the Low Countries.

In-use stocks of products can be considered as intermediaries between human needs and the physical world.

This thesis aims to address offshore wind energy (OWE)-related environmental impacts.

Alzheimer’s disease and cancer are two examples of diseases that are related to malfunctioning cellular patterns. The examination of cell tissue, however, takes a lot of time and generates a lot of data. To make the analysis of data easier, Antonios Somarakis of the Data Science Research Programme (DSRP)…

In May and June of 2021, Bachelor 1 and 2 students of the Faculty of Archaeology joined in the excavation at Oss. After the fieldwork itself, a second post-excavations week started in Leiden where each of them participated in small groups conducting archaeological find processing and working on creative…
