European Research Council funds research into single-molecule devices by atom manipulation

Share this post:

A team formed by IBM Research scientist Dr. Leo Gross, University Regensburg professor Dr. Jascha Repp, and University Santiago de Compostela professor Dr. Diego Peña Gil has received a European Research Center (ERC) Synergy Grant for their project “Single Molecular Devices by Atom Manipulation” (MolDAM). The ERC funding of this interdisciplinary project includes up to more than €9 million, over six years.

Molecules are nature’s fundamental building blocks for life, having countless different roles, properties and functionalities. In MolDAM a team formed by physicists and chemists will aim to control single molecules and chemical bonds at will.

About MolDAM

Simply put, the main goal of MolDAM is to realize physicist and Nobel laureate Richard Feynman’s vision: building up matter from individual atoms the way we want, by controlling chemical reactions with the tip of a scanning probe microscope. This way, the team wants not only to resolve chemical reactions with unprecedented resolution in space and time, but also to discover completely new reactions.

With these funds, novel molecules and nanostructures will be designed and built with atomic precision using atom manipulation with scanning probe microscopes. Using ultrafast light pulses, MolDAM aims at obtaining “movies” of how a bond is formed, observing in time how atoms rearrange in the course of a chemical reaction. Controlling single-electron charges within the custom-built structures will enable the investigation of electron transfer, carrier generation and recombination and redox-reactions at the molecular level. In other words, the team will catch single molecules in action.

Building and studying atomically defined molecular devices on their intrinsic length and time scales will advance our fundamental understanding of the molecular world with impact on the fields of chemical synthesis, light harvesting, molecular machinery and computing.

From HPC Consortium’s success to National Strategic Computing Reserve

Founded in March 2020 just as the pandemic’s wave was starting to wash over the world, the Consortium has brought together 43 members with supercomputing resources. Private and public enterprises, academia, government and technology companies, many of whom are typically rivals. “It is simply unprecedented,” said Dario Gil, Senior Vice President and Director of IBM Research, one of the founding organizations. “The outcomes we’ve achieved, the lessons we’ve learned, and the next steps we have to pursue are all the result of the collective efforts of these Consortium’s community.” The next step? Creating the National Strategic Computing Reserve to help the world be better prepared for future global emergencies.

This ship has no crew and it will transform our understanding of the ocean. Here’s how

IBM is supporting marine research organization ProMare to provide the technologies for the Mayflower Autonomous Ship (MAS). Named after another famous ship from history but very much future focussed, the new Mayflower uses AI and energy from the sun to independently traverse the ocean, gathering vital data to expand our understanding of the factors influencing its health.

The remarkable work of women scientists and researchers at IBM Research

During the month of March, IBM Research put the spotlight on a number of women scientists and engineers, and asked them about their professional and personal motivations, journeys and experiences as women — and particularly, as women in STEM. They represent the breadth of career experiences at IBM Research, across disciplines, geographies, ethnicities, tenures and backgrounds, who share a passion for science and tech, as well as a commitment to help all women rise to meet their aspirations.
