Natuurkundigen, onder wie de Leidse Dorothea Samtleben, bouwen aan een reusachtige onderwatertelescoop om de oorsprong van neutrinos te ontrafelen en het mysterie rond donkere materie op te helderen. De eerste detector is inmiddels geïnstalleerd. Eenmaal af heeft de telescoop het volume van drie kubieke…

Nederland en China kunnen van elkaar leren slimmer om te gaan met afvalwater uit huishoudens en veeteelt. Leidse, Wageningse en Chinese wetenschappers gaan samen met betrokkenen werken aan haalbare oplossingen die milieu, gezondheid en economie vooruit helpen.

Wat heb je aan fundamentele wetenschap? Veel, zo bewijzen de sprekers tijdens Science Matters. Dit symposium werd op 18 maart 2016 gehouden ter ere van het tweehonderd jarig bestaan van de Faculteit der Wiskunde en Natuurwetenschappen.

Bio-energie met koolstofafvang en -opslag is een veelbelovende methode om CO2 uit de atmosfeer te halen en tegelijkertijd energie op te wekken. Maar deze methode is controversieel, omdat er veel grond en water voor nodig is.

This thesis focuses on the design and synthesis of activity-based probes and inhibitors targeting enzymes involved in the degradation of specific plant glycans.

Light-Harvesting Complex II (LHCII) is responsible for light absorption and excitation energy transfer in plants and photosynthetic algae, while in high light it undergoes conformational changes by which it quenches excitations to prevent photodamage.

In this thesis, I studied the origin and evolution of the non-thermal radiation in merging galaxy clusters.

A plasma is an ionized gas with very low electrical resistivity. As such, magnetic field lines are 'frozen in' and move with the fluid. Magnetic field lines that are linked, knotted and tangled, cannot be undone by the fluid motions.

Photocatalysis has emerged as a powerful tool for enabling challenging transformations in organic synthesis. This thesis explores the development of several photocatalytic reactions designed to form carbon-heteroatom bonds from less-functionalized precursors.

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

Molecular complexes can be used as electrocatalysts for oxygen reduction, water oxidation, and/or hydrogen peroxide production.

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

Gold nanoparticles show surprisingly strong interactions with light in the visible range, which can be divided into scattering, absorption, and photoluminescence.

In this thesis, topics relating to the optimization of high-throughput pipelines used for imaging are discussed. In particular, different levels of implementation, i.e., conceptual, software, and hardware, are discussed and the thesis outlines how advances on each level need to be made to make gains…

This thesis covers several aspects of quantum algorithms for near-term quantum computers and its applications to quantum chemistry and material science.

The work in this thesis demonstrates how to obtain an atomic-scale picture of a diverse set of complex surface structures observed using STM, under disparate conditions.

Quantum computers are a proposed fundamentally new type of computer. They aim to perform some computations much faster than previously possible by exploiting phenomena at the quantum scale, called superposition and entanglement.

This thesis investigates the evolution and fate of gaseous exoplanets, which are continuously shaped by stellar activity across both short and long timescales.

This thesis advance our understanding and the application of molecular catalysts relevant to the reduction of oxygen as well as reduction of nitrite.

If mankind wants to survive into the 22nd century, we will need to change the way we live drastically. The human impact on our planet is everywhere, we are changing the atmosphere, the oceans and the land, leading to global warming, climate change, loss of biodiversity and pervasive pollution. There…

Dit boek is een Festschrift ter ere van Sven Vleeming met bijdragen van 38 vrienden en collega’s, onder wie bekende specialisten binnen hun respectievelijke vakgebieden.

Leidse natuurkundigen hebben een nieuwe techniek ontwikkeld om elektrische geleiding te visualiseren in materiaal van gestapelde individuele atoomlagen. Jaap Kautz en Johannes Jobst, die dit jaar de NeVacprijs ontvingen voor hun onderzoek, publiceerden in Nature’s Scientic Reports.

Van waterzuiveringsinstallaties tot een lekkere warme douche, de CO2-uitstoot ten gevolge van het watergebruik in de VS staat gelijk aan dat van 50 miljoen auto’s die een jaar lang rondrijden. In The Washington Post raadpleegt journalist Tik Root verschillende experts om te leren over manieren om ons…

Decentralized plug and play systems for energy production are the future picture of our society. Artificial photosynthetic systems are used for this purpose.

Early time-resolved experiments by Frauenfelder on the ensemble of the kinetic rebinding of CO to myoglobin molecules resulted in a stretched exponential relaxa-tion due to a very large spread of the reaction rates of individual molecules.

The long-held desire - to link structure directly to function and to explain molecular mechanisms based on basic chemical or physical principles - is finally coming closer, satisfying not only our scientific curiosity but also offering new solutions to the many challenges in the field of health, energy…
