PhD Project at CSEM: VISUAL AND NON-VISUAL EFFECTS OF LED-BASED OFFICE LIGHTING ON HUMANS

PhD proposal CSEM

The objective of the proposed PhD project is to investigate and quantify visual and non-visual effects produced by LED lighting on humans across a wide spectral and photometric parameter space. The proposed research will combine the vast experience and facilities of Professors Cajochen and Scartezzini on the physiological aspects of lighting with those of CSEM in the field of integrated light management solutions for solid-state lighting.

PhD Position: Cascade reaction in giant vesicles

Candidates are invited to apply for a PhD position in the field of nanoscience ay of the University of Basel

In the first step the PhD project has the aim to optimize and further develop the formation of giant vesicles with different block polymers.

In a second important step, the aim is to encapsulate enzymes into the giant polymersomes or other polymersomes/liposomes to get compartmentalized vesicles, as well as the insertion of membrane protein into the artificial polymer membrane to from different kinds of nanoreactors

Project: Cascade reaction in giant vesicles

In the first step the formation of giant vesicles with different block polymers has to be established and optimized. It includes the formation of double emulsion droplets with a microfluidic device to from giant polymersomes, similar to the work already published by Weitz et al.1–4 and the further dewetting process3. There are some informative reviews for further information about droplet microfluidics5–7. During the project, there is also the room for new creative ideas for microfluidic devices.

In a second step, the aim is to encapsulate enzymes into the giant polymersomes or other polymersomes/liposomes to get compartmentalized vesicles, as well as the insertion of membrane protein into the artificial polymer membrane to from different kinds of nanoreactors. The applications are broad, as for example in the field of medical application, energy storage, artificial cells as model system or in material science etc. The direction of the project can be chosen in agreement with your supervisor.
