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.

Solute carrier (SLC) transporters are a large and diverse class of relatively understudied transmembrane proteins.

Biodiversity enables ecosystems to thrive through the synergy of functional differences among organisms. While human well-being strongly depends on biodiversity-driven ecosystem services, human actions are also at the root of current unprecedented biodiversity declines.

Op 1 juli 2020 verdedigde Niek Strohmaier zijn proefschrift 'Making Sense of Business Failure'. Het promotieonderzoek is begeleid door promotoren prof.dr. J.A.A. Adriaanse en dr. H. Pluut.

Food security is challenged by a growing global population and by climate change. Drought and soil salinity are considered the most important ones that inhibit crop yield and distribution. Worryingly, climate change is predicted to increase not only their frequency and severity, but also their co-occurrence,…

Globally and regionally, biodiversity is declining and there are shifts in species’ occurrences and functional traits.

Advanced sensing techniques require graphene with high quality and well-controlled surface chemistry.

Pericytes, the mural cells of blood microvessels, are important regulators of vascular morphogenesis and function that have been postulated to mechanically control microvascular diameter through as yet unknown mechanisms.

Metal complexes and 2D materials like graphene were combined to produce structures that can function as sensors.

Het belangrijkste doel van dit onderzoek was het bevorderen van de aspecten van de symbol sense die studenten in staat stellen algebraïsche formules te doorzien en niet-standaard algebra problemen aan te pakken.

The marine shipping industry is one of the strongest emitters of nitrogen oxides (NOx), a pollutant detrimental to ecology and human health. Over the last 20 years, the pollution produced by power plants, the industry sector, and cars has been decreasing.

From 5 to 7 June, the conference "The Senses, Cognition, and the Body in Medieval Devotional Practices" will take place at the University of Padova. The conference programme can be found below. The conference can be attended virtually through the registration link below.

The next generation of high-contrast imaging instruments on space-based observatories requires sophisticated wavefront sensing and control in addition to a high-performance coronagraph.

There is accumulating evidence for an increase in severe global drought events. In particular, Europe experienced several severe droughts in 2003, 2015, and 2018 (unprecedented in the past 2,110 years). Such droughts have caused serious and far-reaching impacts on terrestrial ecosystems.

Leidse fysici ontwikkelden een elegante meetmethode om supersnel elektrische geleiding in superdun materiaal te meten.

Image segmentation is a fundamental task in computer vision, with applications ranging from medical diagnostics to archaeological research.

Single-molecule spectroscopy has become a powerful method for using organic fluorescent molecules in numerous applications.

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.

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

One of the key limitations of the direct imaging of exoplanets at small angular separations are quasi-static speckles that originate from evolving non-common path aberrations (NCPA) to which the primary adaptive optics system is inherently blind. The main focus of this thesis is the development and…

Cardiovascular diseases (CVDs) are the leading global cause of mortality. Endothelial dysfunction, an early reversible stage of CVD development, is marked by decreased nitric oxide production linked to Ca2+ influx in endothelial cells.

In this work, we illustrate unconventional approaches towards the fabrication of edge functionalized graphene nanostructures and bidimensional architectures in polymeric and metallic supports, with an outlook towards molecular sensing devices.

Modeling and analysis of cyber-physical systems are still challenging. One reason is that cyber-physical systems involve many different parts (cyber or physical), of different nature (discrete or continuous), and in constant interaction via sensing and actuating.
