Producing green energy has become the main goal in our society in the search of reducing or eliminating the carbon emission from fossil fuels.

The International Course on Water Use and Management in Cagayan Valley The Philippines (2011-2015)

This thesis examines the impacts and challenges of water use of electric power system. This thesis found that there are large differences in water use of electricity technologies, with hydropower and thermal power being two large water users.

Astronomical observations of cold regions in the universe show a rich inventory of ices. Part of these ices may end up on planets like our own, but in that journey they will be exposed to considerable amounts of radiation.

Water is all around us and is vital for all aspects of life. Studying the various compounds and life forms that inhabit natural waters lets us better understand the world around us.

In the search for sustainable energy solutions, the idea of artificial photosynthesis has been proposed as an approach with which to use water and sunlight to produce hydrogen.

Consequences for sediment stability and seston trapping

To design the ideal water oxidation catalyst, understanding of the catalytic mechanism and decomposition pathways is essential.

In this dissertation iron-based homogeneous catalysts were synthesized, characterized and investigated for water oxidation activity.

As a virtually inexhaustible source, solar energy plays a major role in future global energy scenarios.

Nederland telt een achttal echte eilanden, of negen als ‘Rottum’ (Rottumeroog en Rottumerplaat) voor twee wordt gerekend. Daarnaast zijn er zeventien voormalige eilanden, waar de sfeer van vroeger nog voelbaar is. Jan Bank en Doeko Bosscher, fervente eilandliefhebbers, onderzoeken de geschiedenis van…

Before the large scale use of renewable energy sources can be implemented in our society, the storage of electrical energy needs to be tackled. Storage the energy as hydrogen via the reduction of protons is a good option.

Op 18 januari is de studie ‘Stille wateren hebben diepe gronden – Een analyse van de inkomensverdeling en haar determinanten over de afgelopen veertig jaar’ verschenen. Op deze website kunnen de studie en het achterliggend cijfermateriaal geraadpleegd worden.

In this dissertation, the synthesis and characterization of a series of iron complexes based on different ligand platforms are described.

Climate change is one of the largest challenges faced by humanity. To combat this research into alternatives to fossil fuels is ongoing. Dihydrogen is considered a good alternative fuel, since its burning only forms water.

Ice, the solid state of water, plays an important role on our planet as well as the entire universe.Despite the fact that an individual water molecule has a very simple structure, its chemical bonding in the solid phase can be surprisingly complex.

Biological cells, the basic building blocks of all life forms, are surrounded by a lipid membrane. More than half of the membrane is occupied by membrane proteins, which can regulate the cell functionality through specific arrangements.

Achter de relatief stabiele inkomensongelijkheid in Nederland gaan grote veranderingen schuil. De inkomensongelijkheid is de afgelopen veertig jaar wel toegenomen maar viel vooral minder sterk uit doordat vrouwen in lagere inkomensgroepen meer zijn gaan werken. Ondertussen is het inkomen van mannen…

The intracluster medium (ICM) is a hot, tenuous and X-ray emitting gas that pervades galaxy clusters.

Patterned detectors are an existing technology that can be found in almost all color cameras.

The work presented in this thesis is based on ALMA surveys of protoplanetary disks in three star-forming regions: Lupus, OMC-2, and NGC 2024.

For optimization problems, it is often unclear how to choose the most appropriate optimization algorithm. As such, rigorous benchmarking practices are critical to ensure we can gain as much insight into the strengths and weaknesses of these types of algorithms.

Streptomyces are bacteria abundant in soil that participate in diverse and complex interactions. These bacteria are the main producers of the antibiotics we currently use in the clinic.

Galaxies form and live inside dark matter haloes. As a consequence, they are exposed to the tidal fields generated by the surrounding matter distribution: this imprints a preferential direction to the galaxy shapes, which leads to a coherent alignment on physically close galaxies, called intrinsic a…
