Characterisation And Calibration Of Optical Tweezers

Characterisation and Calibration of Optical Tweezers [Mirror1] Optical Tweezer code Abstract Using the optical tweezers, three different methods of calibrating the trap stiffness were performed: power spectrum fit, sinusoidal movement and finally a flow method. Iinitally in order to understand the equipment I have attempted to characterize the components of the optical tweezers. This involved measurements…

Dipolar Ordering Of Clay Particles In Various Carrior Fluids

Dipolar Ordering of Clay Particles in Various Carrior Fluids  [Mirror] Z. Rozynek, H. Mauroy, R. C. Castberg, K. D. Knudsen and J. O. Fossum We investigate here examples of complexity in composite materials. The objective of the paper is to show that clay particles can be aligned in different hosting media, such as: silicone oil,…

Clay Alignment In Electric Fields

Clay Alignment in Electric Fields [Local Mirror] R. C. Castberg, Z. Rozynek, J. O. Fossum, K. J. Måløy, P. Dommersnes and E. G. Flekkøy The response of rotational alignment of lithium fluorohectorite (Li-Fh) to an external electric field has been studied by employing image analysis. Large aggregates consisting of many single clay particles were prepared using…

Tokyo iced tea

A fantasticly fresh drink with lots of lovely flavours, though be careful, there is quite a bit of alcohol in this and you won’t taste it if you made it right.
