Synthetic microswimmers take an important place within the interdisciplinary field of active soft matter.

This book focuses on the element of thresholds – makeshift gates, makeshift structures and house doors – as concepts of liminality in ancient Near Eastern magical rituals, and the idea of transformation they reflect.

In this thesis, we develop a novel technique called Optical Near-field Electron Microscopy (ONEM), which aims to combine the advantages of both optical and electron microscopy: the high resolution of electron microscopy and the low sample damage of optical microscopy.

How will we generate energy without further contributing to global warming? Industrial ecologist René Kleijn tells about low-carbon energy in tv and radio show Focus, and in VPRO Magazine.

Assistant professor Looi van Kessel writes in The Conversation about the passing of drag performer The Vivienne, reflecting on their significance for LGBTQ+ advocacy in Europe.

This year's RISE Award goes to emeritus professor Jetty Kleijn (LIACS). According to the board of RISE, Kleijn has dedicated herself in the past years to gender equality within LIACS and the Faculty of Mathematics and Natural Sciences. It is the first time since the introduction of the award in 2018…

The recent trade dispute between the U.S. and China has renewed the attention for the dependency of the U.S. and many other developed countries on the imports of critical materials. Recently this has led to an initiative by the U.S. government to team up with resource rich countries like Australia and…

The energy transition ranks high on the European policy agenda, but what does it take to get there? René Kleijn researches how we can extract, use and reuse raw materials in a responsible way. Since 1 March, he has been appointed professor of Resilient resource supply.

This book examines how gender relations were regulated in ancient Near Eastern and biblical law. The textual corpus examined includes the various pertinent law collections, royal decrees and instructions from Mesopotamia and Hatti, and the three biblical legal collections. The book explores issues beginning…

The Van Loon project sets out to safeguard the archives of Dutch archaeologist Maurits van Loon (Amsterdam, September 22, 1923 - Montpellier, October 12, 2006) and make them accessible for further study.

This volume publishes the proceedings of the eleventh annual University of Chicago Oriental Institute Seminar. It uses the sphere of legal institutions as a prism through which to consider gender relations in the ancient world, both in the Near East and beyond. It examines how similar issues were manifested…

Recycling of post consumer plastic waste is problematic in that the environmental benefits are questionable and the costs are significant. It would be better to separately collect the most useful parts through the expansion of the deposit system.

This thesis covers several aspects of quantum algorithms for near-term quantum computers and its applications to quantum chemistry and material science.

The goal of the research presented in this thesis was to explore the chemical space of ruthenium(II) photocages, investigate their ability to host potent chemotherapy drugs, and to red shift the activation wavelength of the most promising PACT candidates to conduct biological studies.

Les Cottés is one the rare site in western Europe with occupations in sequence by the very last Neandertals and the first anatomically modern humans.
