Strange things happen when a crystal gets split in two

05-Feb-2018

When a crystal is broken along certain directions the atoms reorganize in amazing ways. Researchers in Vienna have watched this happen, and have learned to control it. The remarkable strength of ionic crystals is easily explained at the atomic scale: Positively and negatively charged atoms sit ...

Nanowires as Sensors in New Type of Atomic Force Microscope

19-Oct-2016

A new type of atomic force microscope (AFM) uses nanowires as tiny sensors. Unlike standard AFM, the device with a nanowire sensor enables measurements of both the size and direction of forces. Physicists at the University of Basel and at the EPF Lausanne have described these results in the ...

Researchers Watch Catalysts at Work

18-Aug-2016

Physicists at the University of Basel have succeeded in watching a silver catalyst at work for the first time with the aid of an atomic force microscope. The observations made during an Ullmann reaction have allowed the researchers to calculate the energy turnover and, potentially, to optimize ...

Viewing a catalytic reaction in action

Researchers monitors the steps of a chemical reaction mediated by a metallic surface

06-May-2016

To be able to follow and directly visualize how the structure of molecules changes when they undergo complex chemical transformations has been a long-standing goal of chemistry. While reaction intermediates are particularly difficult to identify and characterize due to their short lifetimes, ...

Nuclear Pores Captured on Film

04-May-2016

Using an ultra fast-scanning atomic force microscope, a team of researchers from the University of Basel has filmed “living” nuclear pore complexes at work for the first time. Nuclear pores are molecular machines that control the traffic entering or exiting the cell nucleus. In their article ...

Successful boron-doping of graphene nanoribbon

31-Aug-2015

Physicists at the University of Basel succeed in synthesizing boron-doped graphene nanoribbons and characterizing their structural, electronic and chemical properties. The modified material could potentially be used as a sensor for the ecologically damaging nitrogen oxides. Contrary to usual ...
