Mountain Cedar Pollen

From December through February, many people experience an itchy, runny nose, sneezing, nasal blockage, excess tearing and itchy eyes.If you experience the above symptoms every year during these months, the chance is great that you have Mountain Cedar allergy. This conditions are mostly caused by this pollen.

Micro-Bokeh

Plumbonacrite is metastable form of basic lead carbonate hardly found in nature, as such this mineral has not been completely studied and its properties are not well known. In our research we are interested in the role it plays on the formation of the perovskite PbTiO3.

Phoretic Nano-swimmers

The Scanning Electron Microscope (SEM) image is of ‘Nano Swimmers’ that are currently being investigated for potential use as novel drug carriers. These coiled structures are 25 microns in length, 5 microns in diameter and 300 nanometres in thickness. They are composed of a polymer with nickel/titanium coating and were fabricated by the Multi-Scale Robotics Laboratory, ETH Zurich and in collaboration with the NanoMedicine Laboratory, UCL School of Pharmacy. The swimmers were imaged under a FEI Quanta 200F Scanning Electron Microscope; firstly, the sample was given a 5nm gold coating in a Quorum Q150 Sputter coater and imaged at 5KV. In addition a tilt angle of 65 degrees enhanced their full structure, high resolution digital images were captured and imported into photoshop, where they were artistically manipulated and coloured by Ms Annie Cavanagh.
