This dissertation was to develop effective graphene-based nanofluidic devices by developing scalable fabrication methods and elucidating proton transport mechanisms.

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…

Thanks to its early civilisation and continuous mix of influences, the Muslim world has a rich and varied culture. The study of material culture, books, stories, films and increasingly television series teaches us about the structure of modern-day Muslim societies.

By carrying out fundamental research and providing excellent education, universities become a breeding ground for innovation and entrepreneurship.

This thesis focuses on the application of lipid-based nanomedicine in drug delivery, including small molecular antitumor drugs and biomacromolecules including mRNA, and evaluates their biological performance.

Viral diseases constitute one of the major challenges in modern medicine. Membrane-targeting have broad-spectrum potential and could distinguish viral membranes from the host cell plasma membrane by the difference in membrane curvature.

This thesis describes the development of a variety of mannosylated conjugates. Antigen presenting cells bear mannoside recognizing receptors that actively transport antigen into the cell. This thesis exploits this feature for the development of improved vaccines.

The adsorption of D2 and CO2 on catalyst surfaces is studied using a molecular beam in ultra-high vacuum.

To be eligible for Chemistry at Leiden University, you must meet the following admission requirements.

The programme consists of 60 EC, to be completed in one year.

The adenosine receptors are proteins that reside in the extracellular membranes of cells. Activation of adenosine receptors plays a role in many physiological and pathological processes, such as immune responses and cancers.

Debate, Lunch discussion

Leiden researchers Arko Ghosh and Enea Ceolini analysed the usage data of hundreds of mobile phones and discovered that our body has rhythms ranging between 7 and 52 days. These cycles influence how we behave. Their research resulted in an article in npj Digital Medicine journal, a Nature Portfolio…

Huiselijk geweld is een ingrijpend probleem in Nederland, met jaarlijkse fatale gevolgen. De impact gaat verder dan alleen de slachtoffers zelf en raakt ook nabestaanden en de samenleving als geheel. Tot nu toe/Momenteel ontbreekt het echter aan een gestructureerde manier om fatale gevallen systematisch…

This subproject of 'From Homo Economicus to Political Animal' analyzes Greek economic thinking in late 5th- and 4th-century philosophical circles.

Former Leiden Observatory PhD candidate Danna Qasim has won no less than two prestigious prizes with her thesis, titled 'Dark ice chemistry in interstellar clouds'. Qasim received the IAU PhD Prize from the IAU. The Astrochemistry Subdivision of the American Chemical Society (ACS) honoured her work…

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

Drawing on the analogical lessons of the Great War, this article uses applied history to analyze how the four parallels discerned can help us make sense of contemporary Sino-American rivalry

Since its beginnings, Leiden University has been home to scholars with a broad and diverse expertise in the histories, languages, literatures and material cultures relevant to the study of Jews and Judaism from antiquity to modern times.
