Tiny clumps recycle themselves into complex structures
Manufacturers produce high-end technology mostly top-down with large machinery, but small particles are able to build structures by themselves from the bottom up. A major challenge is that these particles easily clump together. Leiden physicist Daniela Kraft has developed a method to use this phenomenon…

Diagnosing patients with the help of statistical physics
Doctors are there to diagnose and treat people. But sometimes a diagnosis can’t be made or doctors differ in opinion. Luckily, Alireza Mashaghi Tabari and his research team have developed a new framework to solve medical diagnostic problems. This framework can also be applied to many other research…

A matter of dark matter
Is our universe built up out of warm or cold dark matter? The standard model assumes cold dark matter particles, but astronomer Sylvia Ploeckinger is now testing the possibility of a warm counterpart: sterile neutrino’s. For this project, she received an NWO Physics/F grant, a special grant for women…

'Only when you give students freedom, exceptional results are possible'
It doesn't happen every day that the research project of a first-year bachelor’s student results in a scientific publication. And not only that, but as first author and on the cover of a leading physics journal. ‘We have given our lab education a thorough overhaul and it is paying off.’

Polypept(o)ide-based Cylindrical Polymer Brushes as Multifunctional Drug Delivery Systems
The polypept(o)ide hybrid material attracted more and more attention over the past decade by combining the multifunctional characteristics of polypeptides with the shielding characteristics of polypeptoid-pSar possessing similar properties as a shielding material as polvethylene glycol(PEG). Polysarcosine…

Die biblisch-hebräische Partikel נָא im Lichte der antiken Bibelübersetzungen. Unter besonderer Berücksichtigung ihrer vermuteten Höflichkeitsfunktion
My research addresses the function of the much-debated particle -nā in Biblical Hebrew, often translated with “please”, from the point of view of the most important ancient Bible translations (Greek, Syriac, Latin). It combines textual criticism, translation technique, discourse pragmatics, and the…
