The role of material production as a driver of environmental impacts is increasing, which calls for a better understanding of global material flows. This thesis explores the role of in-use stocks of products, buildings and infrastructure as a key driver of global material demand and discusses the implications…

To limit the effects of climate change, global average temperature since pre-industrial measurements are to be kept well below 2 °C preferably even at 1.5 °C.

Where and how are critical materials currently used and how can this information be used to develop scenarios about their future demand.

The energy system is at the heart of two of the greatest challenges of the 21st century: decreasing CO2 emissions to meet the ambitions of the Paris agreement while fulfilling the growing energy demand associated with the economic aspirations of a growing world population.

BioSolar Cells is a five-year research project in which ten knowledge institutions and 45 private industries work together.

There is a linguistic hypothesis that states that all languages from Europe to India originate from a single mother language: Proto-Indo-European. This language is thought to have been spoken thousands of years ago. Researcher Alwin Kloekhorst plans to use linguistic genealogy to study the very first…

How much energy and greenhouse gas emissions can Dutch homes save? Xining Yang uses Leiden as an example and shows with his research how enormous the impact can be. At least, if we work harder on becoming more sustainable. Based on the models he developed, Yang will receive his doctorate on 28 June.

Challenges for the protection of traditional knowledge and genetic resources, traditional cultural expressions, and traditional knowledge of indigenous peoples in the international scenario.

In the CarbonCap project, consumption oriented technological options and policy measures are identified as an addition to the present EU and world climate policy.

In 2018, the number of mobile phone users will reach about 4.9 billion. Assuming an average of 5 photos taken per day using the built-in cameras would result in about 9 trillion photos annually.

Interactive exploration of large volumes of data is increasingly common, as data scientists attempt to extract interesting information from large opaque data sets. This scenario presents a difficult challenge for traditional database systems, as (1) nothing is known about the query workload in advance,…

Relevant safety issues are associated with hazardous materials transportation, especially when transport routes cross populated areas. This article for the Journal of Loss Prevention in the Process of Industries analyses a 2015 accident with a freight train in Tilburg, comparing it to the Viareggio…

The emissions of the Chinese industrial sector alone comprise 24.1% of global emissions (7.8 GtCyr−1 in 2015). This makes Chinese industrial emissions of unique national and international relevance in climate policy. This study reports a literature survey that quantitatively describes the evolution…

Clearance is the most important pharmacokinetic parameter for drug dose selection. Pharmacokinetic information is typically first available in the adult population, and in general only limited pharmacokinetic data are available in children when drugs enter into the market. It is therefore of the utmost…

In Europe a number of production and communication strategies have long tried to establish local products as resources for local development. At the foot of the Alps, this scenario appears in all its contradictions, especially in relation to cheese production. The Heritage Arena focuses on the saga…

This third issue of Ex Novo gathers multidisciplinary contributions addressing mobility to understand patterns of change and continuity in past worlds; reconsider the movement of people, objects, and ideas alongside mobile epistemologies, such as intellectual, scholarly or educative traditions, rituals,…

Middle Paleolithic stone tool technology is one of the major sources of information about Neandertal behavior and adaptations. The Balkan Middle Paleolithic often remains outside of the major debates and interpretations of Neandertal behavior.

A large diversity of exoplanetary systems has been found, but it is still unclear what drives this diversity.
