Mechanical metamaterials are carefully engineered materials whose properties are controlled by their structure, not by their composition, which allows using metamaterials to study and control physical effects in detail⁠.

The application of nanomaterials in industrial processes and consumer products provides many societal benefits, but can also lead to the release of nanomaterials into the environment. The work in this dissertation aims to provide insights into the potential environmental impacts that may follow from…

The archaeology domain produces large amounts of texts, too much to effectively read or manually search through for research. To alleviate this problem, we created a search system (called AGNES), which combines full text search with entity and geographical search.

The main focus of this thesis is the behaviour of two-dimensional materials, namely (anti)-ferromagnetic materials in the first two chapters, which show topological phases, and energetic square ice in the third and fourth chapter.

In eight chapters, the thesis of Rafaël Vos covers the effect of temperature and pressure on the electrochemical CO2 reduction.

This volume was edited by Jeroen Duindam, Jill Harries, Caroline Humfress, and Nimrod Hurvitz.

The aim of current study was to develop a dried inactivated polio vaccine (IPV) formulation with minimal loss during the drying process and improved stability when compared with the conventional liquid IPV.

How have British cities changed in the years since the Second World War? And what drove this transformation? This innovative new history traces the development of the post-war British city, from the 1940s era of reconstruction, through the rise and fall of modernist urban renewal, up to the present-day…

In this thesis, two potential therapeutic targets for diabetic nephropathy were dentified and investigated. First, we show that glomerular clusterin is upregulated in diabetic nephropathy and demonstrated that recombinant clusterin protein can protect the podocytes against oxidative stress in vitro.…

This article aims to explore the determinants of inclusive leadership. This type of leadership is valued for social equity and fairness.

Deepfakes are videos that have been manipulated to replace one person’s likeness with that of another. They can be difficult to distinguish from authentic videos. In our study, we found that people who score high on conspiracy thinking and people who use social media more are better at distinguishing…

This thesis tackles the urgent challenge of antimicrobial resistance (AMR) through the design of novel antibacterial agents.

Hydrogen peroxide (H2O2) generation via electrochemical oxygen reduction is a sustainable production method for this bulk chemical. However, the selectivity of molecular catalysts for electrochemical H2O2 generation has hardly been investigated in a systematic manner, and it is unknown if their stability…

In Chapter 1 we provide some background information about modular forms, describe the correspondence between half-integral and integer weight modular forms and explain how the coefficients of half-integral weight modular forms encode the central values of L-functions of twisted modular forms.

In this thesis, both the obscured and unobscured star formation of high-redshift galaxies (UV-bright galaxies and serendipitously identified [CII]-emitters) is investigated.

Efficiently responding to others’ emotions has great survival value, especially for social species, such as primates, who establish close, long-term bonds with group members. The closest living relatives to humans are the chimpanzee and the bonobo. Studying these species, and comparing them on the exact…

How do we get to the strategic plan? The infographic below shows the path we are taking in the coming period.

The STRINGS project is mapping development pathways for science, technology and innovation that best address the UN Sustainable Development Goals. A consortium of seven universities led by Tommaso Ciarli at SPRU at the University of Sussex and the UNDP (United Nations Development Programme) have worked…

Spontaneously helping one another, why do we bother? It is believed that lending a hand to others promotes social bonding, helping us to connect with each other and even build friendships. In our experiment, in which the adult researcher ‘accidentally’ dropped matches on the floor, most adolescents…

This article discusses the coevolution of several species of the tribe Phyllantheae and moths of the genus Epicephala.

We have examined sequences from the ligand-binding domain of the nicotinic acetyl choline receptor (nAChR) in 148 vertebrate species. We are in interested in this receptor because the α-neurotoxins of many venomous snakes binds to this receptor in its location at the neuromuscular junction in all ve…

This thesis contains results on the arithmetic and geometry of del Pezzo surfaces of degree 1.In Chapter 1 we give the necessary background, assuming the reader is familiar with algebraic geometry.

How do urban residents in Brazil and the Netherlands (The Hague and Leiden) perceive the cultural benefits of urban forests? How are these benefits spatially distributed across cities? How do socio-demographic factors shape these perceptions, and do these differences vary between countries?

In Quantum mechanics, particles can be in multiple positions simultaneously. Yet, when a measurement is made, the particle is found only in one place. Technology has come to a point where we may design experiments that will tell us how.

In this thesis, we investigate how deep generative models (AI models that can create new designs) can be better utilized for technical and industrial design. Our goal is to generate designs that are not only realistic (plausible), but also efficient, reliable, and usable in complex 2D and 3D applica…

This article describes the phenomenon of firearms violence and the importance of including non-lethal firearms violence in understanding this phenomenon.

This thesis is comprised of three chapters covering the theme of studying semistable varieties by looking at their dual combinatorial objects.

This work describes several studies into the electroreduction of carbon dioxide (CO2RR), both regarding mechanistical aspects and catalyst stability considerations. Mechanistic insights into carbon-carbon bond formation on a silver catalyst are described in Ch 2, were we find an acetaldehyde-like surface…

This article by Honorata Mazepus and Florian van Leeuwen in the journal Governance: An International Journal of Policy, Administration and Institutions looks at how evaluations of authorities were influenced by four aspects of a governmental response to a hypothetical disaster.

This thesis is a (biased) journey through very different topics in astrophysics: quasars and new populations of active galactic nuclei, gravitational waves from merging black holes, and protoplanetary discs around young stars.

Breast cancer is the most common cancer in women worldwide. Metastasis, the process by which cancer cells spread to other parts of the body, makes treatments less effective. It is important to unravel the mechanism of metastasis.

A management strategy has been developed for field margins to reduce pesticide drift to non-target areas and to promote biodiversity on arable land. To this end, 3 and 6 m wide strips along the edges of winter wheat, sugar beet and potato crops have been left unsprayed with herbicides and insecticides…
