Tin electrodeposition applications have rapidly evolved in the past 25 years.

Food production in the Netherlands is an economic success but has led to many environmental issues, including nitrogen pollution. Recently, the policy to allow economic growth while reducing nitrogen losses was disapproved by the highest court in the Netherlands, casting the country into a nitrogen…

Door onduidelijke stikstofregels komen milieuzaken steeds vaker voor de rechter. De zaak van een Reeuwijkse varkenshouder leidt al tientallen jaren lang tot een getouwtrek tussen een milieuorganisatie, de provincie en de rechter. Rogier Kegge, universitair docent Staats- en bestuursrecht, bespreekt…

Voters sent a clear signal in the recent Dutch provincial council elections with the 'monster' victory for the Farmer-Citizen Movement (BoerBurgerBeweging, BBB). This sign of ‘social resistance’ has consequences for the policy on nitrogen emissions, according to Geerten Boogaard, Professor of Local…

Stratigraphy, Palaeoenvironment and Archaeology of the Middle and Late Pleistocene Deposits.

Geology and Paleobotany of the Area surrounding the Archaeological Excavation at the Hazendonk River Dune (Western Netherlands).

In Bronze Age Europe, an enormous amount of metalwork was buried in the ground and never retrieved.

The Cryogenics Department has a liquid helium production unit and an automatic liquid nitrogen filling plant.

The Leiden Science Young Talent Award is awarded yearly to a student who completed their bachelor’s degree with an excellent thesis.

Planets are formed in disks of gas and dust around young stars.

Ongoing microwear analysis of the flint artefacts from the Funnelbeaker period suggests that flint had a pivotal role in the representation and structuration of the cosmological order of Funnelbeaker society.

The Great Rift Valley in Africa is a real treasure trove for discovering early human fossils. The fossils found in this part of Africa have determined our view of human evolution. But was the Great Rift Valley really the place where evolution took place or just a place where fossils are well preserved…

Exploring Late Bronze Age attitudes towards martiality through experimentation and micro-wear analysis

A study on the utilisation of Iron Age rectangular structures and related depositional practices in the Low Countries

This project investigates the causes of the major archaeological change in the period of 40.000-20.000 BC in South Africa.

Crises like climate change and loss of biodiversity threaten our planet. That’s why sustainability is an important topic in research and education across Leiden University. On this website you read how scientists from many disciplines work together in researching sustainability.

We investigate the processes underlying the patterns. We aim to explain biodiversity by investigating the distribution, function, development, and evolution of body forms, as well as physiological and behavioural variety among species. We collaborate with those specialized in describing, archiving,…

Photocatalysis has emerged as a powerful tool for enabling challenging transformations in organic synthesis. This thesis explores the development of several photocatalytic reactions designed to form carbon-heteroatom bonds from less-functionalized precursors.

This thesis investigates the structural evolution and assembly of galaxies since the first few billions years after the big bang.

This thesis explores interfacial conductance and electric field-effects in LaAlO3/SrTiO3 heterostructures.

The aim of this project is to gain a better understanding of daily life, diet, mobility and health in late medieval Zeeland, as well as to test the potential of multi-isotopic analyses on a Dutch assemblage.

D. Fontijn, Quentin Bourgeois & Arjan Louwen (eds) (2012). This publication describes the history of “barrow landscape” near Echoput in Apeldoorn. Two burial mounds were examined and it became clear that our prehistoric predecessors carefully managed and maintained the open area for a long time, before…

Death, fire and identity in North-West Europe

In the Aarts lab we combine or structure materials, mostly in thin film form, in such a way that the hybrid has different and novel properties or functionalities.

Following the Beirut explosion, BBC's podcast series The Foodchain explores the chemical that caused the blast: ammonium nitrate. A compound that is widely used to produce fertilizer. Professor of Environmental sustaibability Jan Willem Erisman tells about the effects of nitrogen on the environment.

As part of LUGO’s focus on responsible recycling of e-waste (electronic waste) we participated in the Funky Phone Challenge.

Why should you publish your data? ... and how?

It is with great pleasure that we present to you the second volume of Inter-Section, published in 2016.

A Study of Middle Palaeolithic Riverside Settlements at Maastricht-Belvédère (The Netherlands).

The Western Mediterranean is a key region to understand human dispersal events within and out of the African continent as well as for the eventual replacement of Neanderthals by anatomically modern humans during the Pleistocene. Central to any conclusive interpretation of archaeological and palaeoclimatic…

Professor David Fontijn is fascinated by the question why people destroy objects that are dear to them. It is a phenomenon that you find everywhere in the world, gaining particular strength in the European Bronze Age. Fontijn wrote a book on this ‘economy of destruction’, published by Routledge.

The Middle Paleolithic site of Neumark was first discovered in the 1980’s by German geologist Matthias Thomae.

The research within the Food research programme at CML focuses on a transition towards sustainable food production and consumption systems. We investigate from a very small to a very large scale, at a local, national or international level. We do so by researching for example molecular tools, food systems,…

On 1 October 2019 the Hazelhoff Centre for Financial law hosted its 19th guest lecture starring Paul Sharma, managing director at Alvarez & Marsal and co-head of the European Financial Industry Regulatory Advisory Services practices.

MICRO-biome climate smart applications: Can we use indigenous microbial rice communities to reduce methane production in agricultural settings?

One of the key discoveries in exoplanet research over the past decade is the abundance of small planets in our Milky Way. Despite their high numbers, our understanding of their atmospheres remains limited, and it is unknown if they possess atmospheres at all.

Streptomyces are prolific producers of enzymes and secondary metabolites, including more than 50% of all clinical antibiotics. This makes them highly attractive for medical, biotechnological, and industrial purposes.

A dense region of a gaseous and dusty cloud collapses to form a protostar surrounded by a disk and an envelope. This thesis uses both observations and models to study physical and chemical conditions of these protostellar systems which are likely where planets start to form.
