In this project innovative technology for photovoltaics cells is developed and analysis of ecological and health related risks are explicitly accounted for.

OB associations are loose groups of young, massive stars. They constitute the last stage of the massive starformation process, and the context in which new stars are formed.

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.

With the energy transition toward a renewable energy supply and a CO2-neutral economy, electrification of the energy system is rising in importance, which leads to the challenge of long-term storage of renewable electricity.

In this research I assess the impact of the recently discovered gas reserves south off Cyprus on the escalation of the Cyprus conflict.

Het Solar Fish-project van hoogleraar biofysische organische chemie Huub de Groot, krijgt een plaats in het Llowlab op popfestival Lowlands.

The Honours Class From Solar to Fuel with Bio bestond vrijwel geheel uit de workshop Solar Biofuels from Microorganisms die eind maart/begin april ruim tachtig specialistische onderzoekers naar het Lorentz Center trok. De studenten Erica Wenker (scheikunde) en Jasper van Dobben de Bruijn (rechten) schreven…

Wetenschappers zijn druk bezig zonne-energie vast te leggen in CO2-neutrale ‘solar fuels’. Dat klinkt veelbelovend, maar er is ook kritiek. Zijn die brandstoffen wel echt wel CO2-neutraal en maakt concurrentie door alternatieven ze niet overbodig?

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.

Scattering of light in the presence of nano-structured materials, i.e. with features in the order of the wavelength of the light or smaller, reveals details of how light interacts with matter at the nanoscale.

What performance criteria does a new technology have to fulfill in order to be added to the list of future energy options and what constraints exist in terms of broad market penetration?

What are the life-cycle environmental impacts and risks to human health and ecosystems of a III-V/Si PV system? How can these be expected to change when the system is deployed at industrial scale? What are the most favourable recycling scenarios?

What is the environmental impact, the human health impact and the life cycle and production costs of the lab, pilot and commercial diffusion of nanowires and nanowire-based photovoltaic technologies?

The development of new environmentally sound technologies is seen as a key route towards achieving sustainability.

Over the past years it has been discovered that the population of extra-solar planets is large and diverse.

A century ago, it was unclear whether the stars in the sky were clustered in groups, or widely spread in the universe.

The growing demand of energy indicates that global energy resources in the form of fossil fuels will not be sufficient in the future. In order to solve potential future energy problems development of a sustainable hydrogen economy is highly desirable.

Human civilization consumes a huge amount of fossil fuels, which has resulted in an atmospheric CO2 level which has not been higher in over 800 millennia.

Planten, algen en bacteriën zetten zonlicht om in chemische energie. In een workshop van het Lorentz Center inventariseren onderzoekers de mogelijkheden om dit proces van fotosynthese te benutten en imiteren, met het oog op een duurzame brandstofvoorziening. De vrijdagmiddagsessie is openbaar.

Solar energy is used by photosynthetic organisms to drive energy required cellular processes. Is absorbed by two groups of pigments, located in the LHCs.

Sustainable energy from wind and solar is most readily available near the sea.

Solar energy harnessed by plants and algae has great potential to be converted into biofuels for future generations.

Ondanks de snelle vooruitgang in zonne- en windenergie blijft een volledig schone energievoorziening een enorme uitdaging. Sectoren als de zware industrie en de transportsector kunnen nog niet zonder koolstofhoudende brandstoffen. Willen we toch de klimaatdoelen behalen, dan moet ook in deze sectoren…

The thesis explores how interstellar chemistry evolves as a function of time and changing physical architectures during the formation of stars.

Hot astrophysical plasma is ubiquitous in the Universe, from comets in our Solar system to the largest scale structures -- the cosmic web filaments. These hot plasmas, with the temperature of a few millions of degrees, are often observed in the X-ray wavelength range.

This thesis describes the development and validation of new high-contrast imaging techniques, with the ultimate goal of enabling the next generation of instruments for ELT-class telescopes to directly image Earth-like extra-solar planets orbiting around nearby stars.

In this thesis chemical and physical processes in the ice mantles on interstellar dust grains are studied.

Synthetische brandstof is schoner dan natuurlijke olie, maar het productieproces is nog niet efficiënt genoeg. Nu hebben wetenschappers voor het eerst direct de moleculen waargenomen die uit het chemische proces ontstaan. Het opent de deur richting efficiënte ‘designer’ katalysatoren. Publicatie op…
