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.

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.

Metal production is not only energy-intensive and a major source of greenhouse gas (GHG) emissions, but is also associated with other impacts affecting human health and ecosystems.

What is the effect of light at night on plant phenology and physiology, and how does this affect plant interactions with other species?

Lorenza Colzato wil onderzoeken of het gebruik van probiotica en tryptofaan de sociaal-cognitieve achteruitgang die optreedt bij het ouder worden, kan vertragen. Daarvoor ontvangt Colzato samen met haar collega's in Duitsland en Spanje een JPI 'A Healthy Diet for A Healthy Life' Joint Transnational…

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.

This thesis focuses on the social dimensions of crane and wetland conservation in rural landscapes in Kenya, Uganda and Zimbabwe.

The investigations described in this thesis lay out strategies aimed at advancing antibiotic research and development. The examples presented revolve around two main approaches: understanding drug-target interactions and target identification.

To conclude, this thesis provides valuable methodological insights to address data gaps and improve environmental impact assessments within the circular economy, with a particular focus on product reuse and sharing practices. Through empirical analysis and innovative approaches, it aims to support informed…

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.

This study has been carried out in the community of Sukamiskin, a kelurahan (‘village’) in Bandung, the Capital of West Java Province, located in the Sunda Region of Indonesia.

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

Afgelopen jaar zijn ongeveer 2000 internationale studenten gestart met een master aan de Universiteit Leiden.

IoT technology poses serval opportunities to supply chains. This thesis employs grey correlation and forecasting models, system dynamics, agent-based modeling, and ex-ante LCA to investigate and quantify the opportunities and risks of IoT-enabled sustainable supply chain operations from both industrial…

There are many interpretations of quantum mechanics, and ultimately experiments are needed to verify or falsify these interpretations.

Geometric phases lead to a nontrivial interference result when an electron's different quantum mechanical paths choices encircle a magnetic coil in an Aharonov-Bohm experiment.

Microbiome composition of the spermosphere and the rhizosphere of wild and modern bean accessions grown in an agricultural and a native soil from Colombia was characterized by metagenomics and cultivation-dependent approaches.

Plant-microbe interaction resulted in different physio/chemical responses by host plant and interacting rhizobacteria.

The spindle-assembly checkpoint (SAC) is a safety mechanism which secures accurate chromosome segregation during mitosis.

Increasing the efficiency of gene targeting (GT) as a genome editing tool in plants has been an important goal in plant biotechnology.
