Electron Optics: Symposium in London

CAD in light optics and electron optics

In 1854 J. C. Maxwell devised his fish-eye lens a sphere with a radially diminishing refractive index [*1. The optical characteristics of this lens, which can produce aperfect image of an object, as the computer plot above suggests, are fairly easy to calculate analytically. This is not generally the case with optical elements of varying refractive index as used today for data transmission. The...

Electron optics in graphene

In ballistic graphene, electrons behave in many ways similar to photons. By changing the electrostatic potential locally, we realized elements in graphene that are known from optics. But in contrast to conventional optics, gapless p-n interfaces can be formed showing a negative index of refraction and the effect of Klein tunneling. Even more, electron trajectories can be bent by applying a magn...

Symposium on Pharmacovigilance of Herbal Medicines, London, March 28, 2006

On April 2006, the International Symposium ‘Pharmacovigilance of Herbal Medicines. Current Status and Future Directions’, was held in London, organized by the Royal Pharmaceutical Society of Great Britain (RPSGB) in conjunction with the most important international societies involved in the field. The Chairperson of the Congress was Prof. Joanna Barnes of the School of Pharmacy of the Universit...
