While bioinformatics methods deal with the analysis of sequence information (be it proteins or DNA), the field of cheminformatics is concerned with the analysis of small-molecule datasets.

This dissertation for the first time provides a detailed description of Benchnon, a language spoken by approximately 200.000 people in Southwest Ethiopia.

The dissociative chemisorption of methane on metal surfaces is of fundamental and practical interest, being a rate-limiting step in the steam reforming process. The reaction is best modeled with quantum dynamics calculations, but these are currently not guaranteed to produce accurate results because…

This research focuses on the (Quantum) Dynamics (QD) of the reactive scattering of H2 from metal surfaces.

The global population speaks approximately 7,000 different languages and approximately half of the world’s population is bilingual. The unique orthographic characteristics of different languages can help us to gain insight into the seemingly simple process of transforming written to spoken words (i.e.,…

The solar system was formed approximately 4.56 billion years ago. Despite the numerous theories that have been developed over the years, the formation and evolution of the solar system still remain unclear.

The Department of Bachelor's Education staffs the workgroup education and safeguards the quality of the teaching of the workgroup education in the bachelor's programme in psychology.

Poly(lactic-co-glycolic acid) (PLGA) particles have been extensively studied as biodegradable delivery system to improve the potency and safety of protein-based vaccines. In this study we analyzed how the size of PLGA particles, and hence their ability to be engulfed by dendritic cells (DC), affects…

The LED3 Network, consisting of researchers from the Leiden Institute of Chemistry (LIC), the Institute of Biology Leiden (IBL) and the Leiden Academic Centre for Drug Research (LACDR), is very excited to organise the “LED3 Chemical Biology Talks”. This lecture series brings excellent researchers in…

Chemical reactions go hand-in-hand with an energy exchange with the environment in which they take place. Surfaces offer a variety of energy dissipation channels, constituted by the nuclear and electronic degrees of freedom of the atoms at the interface. Aiming at an improved future harvesting of energy,…

This book presents a comprehensive description of the grammar of Logba, one of the fourteen Ghana-Togo Mountain (GTM) languages spoken by approximately 7,500 speakers on the South-Eastern frontier of the Ghana-Togo border. It is the outcome of fifteen months research in Logba speaking communities.

As soon as young children are introduced to rules and start to learn to obey to those rules, it can be difficult for parents to remain sensitive when their children try to bend or break those rules. The short-term (preventive) VIPP-SD intervention aims at enhancing parental sensitivity in interaction…

Adverse drug reactions (ADRs) remain one of the major reasons for patient mortality and (early) drug withdrawal. Currently, different in vivo and in vitro models are used to assess the toxic potential of drugs in the pre-clinical phase. Unfortunately, the predictive value of this model does not fit…
