Van der Waals at its best!

Physicists measure van der Waals forces of individual atoms for the first time. Prof. Ernst Meyer et al, have succeeded in measuring the very weak van der Waals forces between individual atoms for the first time. To do this, they fixed individual noble gas atoms within a molecular network and determined the interactions with a single xenon atom that they had positioned at the tip of an atomic force microscope.

Prof. Ernst Meyer asked Scixel for a visual representation of their work, published in Nature Communications.

On fuelling biological machines

If I got this right, Dr. Ivan Lopez Montero et al, had fuelled ATPases by placing them in a lipid membrane over a modified metallic surface. Using this surface as an electrode, now they can make ATPase work creating ATP molecules wherever they are needed… Yes, I’m not kidding.

This is the kind of research that make you fantasize about the near future. Not surprise that their work made the cover of Angewandte Chemie International Edition

Pushing AFM capabilities to the limit

AFM was invented 35 years ago. Then, its capabilities were already impressive. But 35 years later, researchers have boosted its sensitivity and amazingly spread its spectrum of the quantities measured. Ricardo Garcia’s group, ForceTool, has participated in this process in a prominent position. In this last work , they’ve pushed these boundaries yet a little further.

This work is the result of the collaboration of Pataata and Scixel. We are expecting it to be just the first of many.
