Cars, wind turbines, solar panels and smartphones. ‘Critical’ raw materials like platinum or cobalt are used in all the technologies that are essential for the energy and digital transition. But we should be aware of the scarceness of these materials, a new campaign warns.

With its Green Deal The European Union has set itself much-needed ambitious climate goals. But the energy crisis and geopolitical tensions are making these difficult to achieve. Seven researchers from the Leiden-Delft-Erasmus Universities (LDE) alliance have written a white paper offering solutions.

The Early Irish Hands project is inviting applications for a one-day Work-in-Progress workshop on materiality. Extended deadline: 7 February 2023.

Materials are either gas, liquid or solid, based on how their molecules respond to temperature and pressure. But what if the building blocks are self-spinning particles instead of ordinary molecules? Theoretical physicists found out what determines the phase of those artificial materials. Publication…

A scenario building web-tool and knowledge package to enable multi-level decision making for the transition to the Circular Economy

Minute nanoparticles are bringing about a completely new industrial revolution. But little is known about the possible dangers to the food chain. An international group will be examining this issue, and Leiden researchers will be playing a key role.

Materials like concrete, steel, plastic and fertiliser shape the world around us, but they’re also extremely polluting. If we want to build a more sustainable society, we can learn a lot from archeologists. How do we relate to these materials? And are there alternatives? Maikel Kuijpers is writing a…

This research develops and applies a new approach to study Aegyptiaca Romana from a bottom-up, Roman perspective.

An experimental approach to organic palaeolithic technology

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.

Scientists have developed a material that breaks one of the fundamental principles governing many physical systems. Ordinary materials transmit external forces equally, no matter where the pressure comes from. The newly developed material breaks this rule and could potentially be of interest in soft-robotics…

How an initially valueless object becomes worth hundreds of millions. And vice versa.

A number of different course curricula were presented at a training conference on ‘Islam in the Class’ op 17 November. The course materials were developed by Leiden academics in collaboration with teachers involved in pre-university education.

Martin van Hecke en Anne Meeussen publiceren in het tijdschrift Nature over mechanische metamaterialen. Ze hebben een nieuwe klasse multistabiele materialen ontdekt. Dit is gebaseerd op ribbeltjes plastic.

This year’s edition of the prestigious art festival Ruhrtriennale, carried in diverse locations around the cities of Essen, Bochum and Duisburg (Germany), has re-staged De Materie, ACPA professor Louis Andriessen’s exceptional opera which overcomes traditional patterns of the genre in terms of dramaturgy,…

Studying ancient materials and the way they were made can give us groundbreaking insights into the past. Not only that, the interplay between people and materials is highly relevant for society today, says Ann Brysbaert, Professor of Ancient Technologies, Crafts and Materials, at the Faculty of Archaeology.…

Students taking the new bachelor’s course ‘Social Movements and Political Violence’ are about to do something new. In addition to studying textbooks and academic articles, they will actively work with multimedia materials and engage in online storytelling. Course instructor Corinna Jentzsch (Leiden…

It appears to be a paradox: ultra-thin material that absorbs all the incident light. Nonetheless, it does exist. Two Leiden researchers report on their research in ‘Applied Physics Letters’. The article is among the Top 20 of the most downloaded articles of this reputable journal in May.

Researchers at FOM-institute AMOLF and the Leiden Institute of Physics (LION) have developed a rubber rod with strange bending behaviours. Beyond a certain point, it bends more under decreasing pressure. This behaviour doesn’t fit our expectations and does not conform to secular laws that predict the…

Astronomers from, among others, SRON and Leiden Observatory have discovered long-sought intergalactic gas with ESA’s space telescope XMM-Newton. This gas is one of the pieces of the puzzle to map the total amount of ‘normal’ matter in the universe. The research will be published in Nature on 21 June…

Annelou van Gijn and Diederik Pomstra took part in the Shire Project in Tigray, northern Ethiopia, to contribute to an exciting mix of lithic and use-wear analysis, as well as ethno-archaeological and experimental studies.

Martin van Hecke published an article in Nature, together with physicists from AMOLF and UvA. They have developed a metamaterial that folds itself up, even in multiple steps. Van Hecke appeared in the following media.

We live in a world of things and people in the past must have been as closely entangled with their material surroundings as we are now. In the Laboratory for Artefact Studies Van Gijn takes a close look at the biographies of objects: what kind of raw material an object is made off and what is its provenience,…

The electrochemical reduction of a group of organic compounds on platinum is strongly dependent on the arrangement of the atoms in the platinum surface. Christoph Bondue, postdoc in Marc Koper's group, published this in Nature Catalysis on 4 March. The reduction of such compounds is an important process…

Asteroids, pieces of matter orbiting round the sun, have turned out to be extremely valuable. Asteroid Psyche contains a quantity of metals that together are worth more than the entire global economy. NASA is heading for it.

Complex Structures Made Simple - Continuous Flow Production of Core Cross-Linked Polymeric Micelles for Paclitaxel Pro-Drug-Delivery

In unconventional high temperature superconductors, supercurrent vortices are known to spoil the Landau levels. In this thesis the emergence of Landau levels is studied in different types of superconductors: Weyl superconductors, and the Fu-Kane heterostructure.

The material and intellectual presence of Egypt is at the heart of Western culture, religion and art from Antiquity to the present. This volume aims to provide a long term and interdisciplinary perspective on Egypt and its mnemohistory, taking theories on objects and their agency as its main point of…
