This thesis is concerned with the constitution of chiral responsive matrix assemblies that may undergo light-driven conformational changes and self-select vibrations to develop vibronic states for driving semi-classical coherent transfer with nearly 100% yield in a lossless NCAP process.

This thesis investigated how microphones and loudspeakers could become musical instruments.

Multicellular giant algae Chara species have been widely used in physiological studies for decades.

Confetti, stilt walkers and the new Einstein Fountain. On Monday, 2 September, the Gorlaeus Building of the Faculty of Science was festively opened. Together with Constantijn van Oranje, our students cut the ribbon. Dean Jasper Knoester: ‘The building is ready, now it is up to our students and researchers…

Fewer CO2 emissions, less airborne viral transmission, and a more sustainable form of food production: seven consortia of researchers and societal partners will put a budget of 32 million euros towards developing technological innovations. Important Leiden research on circular electronics by Prof. Dr.…

Leiden physicist Milan Allan and his group have discovered an apparent paradox within a material that has zero electrical resistance. They measured trapped charges, while charges should in theory keep flowing in the absence of resistance. The discovery could provide a missing piece of one of the big…

This thesis proposes multiple paths towards the development of a performance practice in Computer Music.

During post-embryonic development into adults, animals face an environment that fluctuates constantly. For example, in nutrient availability, temperature, and osmolarity (e.g., salt concentration).

A consortium of researchers from the Leiden Institute of Physics (LION), the Institute of Biology Leiden (IBL), and the Leiden Institute of Chemistry (LIC) received a FOM program grant to develop a novel way of studying individual proteins inside a cell using gold nanorods.

Aleydis Nissen published a feature article on the South Korean electronics industry in Eos magazine. The Pascal Decroos Fund sponsored this article.

How can you ensure that more experimental drugs reach the finish line? At the moment, only one in twenty cancer drugs that are tested on humans makes it to the market. This is an enormous loss for patients and society. With a grant from the National Growth Fund, Oncode-PACT aims to efficiently select…

STM scanning experiments on poorly conducting materials are challenging, and can cause a distortion effect. A new model corrects for this effect, allowing physicists to better study materials in their quest to understand unconventional superconductivity. Publication in Physical Review B as Editor’s…

In my research, I used a comparative wood anatomical approach to address wood evolution of the (largely) tropical flowering plant families Apocynaceae and Sapotaceae.

Hydrodesulfurization (HDS) is an ubiquitous part of oil refining that ensures that fuels are cleaned of impurities and environment release of pollutants such as SOx and NOx gasses are minimized.

The thesis describes the use of electron paramagnetic resonance (EPR) spectroscopy, in continuous wave and pulse modes, to address the interaction of α-Synuclein (αS) with membranes and the aggregation of αS.

What started as an idea during a social gathering led to an unexpected breakthrough in research on resistant bacteria. Biologists and chemists from Leiden developed a new substance that proves to be effective against bacteria resistant to antibiotics. They published their discovery in Nature Chemist…

On Monday 27 October, Jasper goes on safari in the Van Steenis building. And will he manage to stay dry more often than he gets soaked cycling between meetings? You’ll find out – along with the rest of Jasper’s day – in this column.

I will give a general introduction to the field of molecular electronics, its history, methods and challenges. I will also introduce the subject of my investigation and provide a brief outlook to the remainder of our thesis.

The nanoscale structure of a catalyst under reaction conditions determines its activity, selectivity, and stability. For the production of sustainable energy and materials, new catalysts are needed. By understanding the structure-activity relationships of catalysts under reaction conditions, insight…

The majority (80%) of e-waste generated globally are recycled informally in developing countries.

This thesis describes the synthesis, analysis of various tetrazine bearing compounds and use in bioorthogonal chemistry.

To construct catalysts that can produce fuels from CO2 innumerable times, we need to learn much more about how catalysis works. Irene Groot is conducting groundbreaking research into catalysis at the atomic level.

Composer, bass player and ACPA alumnus Ilya Ziblat Shay presented a paper at the Music Weekend and Midlands New Music Symposium, organised by Nottingham Forum for Artistic Research.

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.
