In 2013, we proposed the organization of a molecule-car race
with different molecule-vehicles driven one by one, at the same time, by
pilots using different scanning tunneling microscopes (STM) and on the
same surface [1]. This was one consequence of a long period of research
on single molecule mechanics started with the first observation of a
single molecule in rotation [2] and followed by the construction of a
few molecule(s) machinery like the single molecule-wheelbarrow [3], the
molecular rack and pinion [4], a single molecule-rotor [5] and the first
observation that a single molecule alone has enough power to rotate one
way a few atoms [6] or another molecule [7].

With about 100 atoms, a molecule-vehicle has a molecular chassis
equipped with spacer chemical groups to hold it a few angstrom away from
the surface, paddles, switchable legs or wheels and a motorization
embedded on board [1]. For this first edition, pushing its
molecule-vehicle using the known pushing, pulling or sliding STM
manipulation modes was forbidden forcing each team to play with
inelastic tunneling effects for a drive on the Au(111) surface [8]. The
27th of April 2017 at 11:00 am, the departure flag was up in the
Toulouse control room with the 6 selected teams from around the world on
their starting atomic line, ready to nano-race. The anticipated run was
100 nm on a single Au(111) surface with 2 turns. After 2 days and one
night of intense efforts, the 29th of April 2017 at 17:00 pm, the first
ever international nano-car race was a success. We will describe the UHV
technologies created on purpose for this race involving in particular a
unique LT-UHV 4-STM i.e. a scanning tunneling microscope with 4 scanners
able to scan on the same surface and a special UHV sublimation system
with a dedicated masking set-up. We will present some of the nano-car
race sequences recorded during those 36 hours.

In 2018, we have announced the nano-car race second edition for spring
2021 organized under the new MEMO (Mechanics with molecule(s)) European
project. Ten teams from all over the world are already officially
registered [9]. The rules of this second edition will be given in a way
to attract more teams to join the fun of designing, synthesizing and
operating a single molecule machinery on a surface.

About the speaker:
Christian Joachim
is Director of Research Fellow (CNRS) at the
Nanoscience group CEMES/CNRS in Toulouse and since 2008 adjunct
Professor of Quantum Physics and Quantum Engineering at ISAE-Sup'Aero.
He was A*STAR VIP Atom Tech in Singapore (2005-2014) and is WPI
MANA-NIMS in Tsukuba since 2008. He had coordinated the Integrated
European projects "Bottom-up Nanomachines", "Pico-Inside" and "AtMol"
with the objective to construct the first ever molecular chip. He has
published more than 300 scientific publications (h-index = 59)
accompanied with over 380 invited talks on electron transfer through a
molecule, STM and Atomic Force Microscopy (AFM) image calculations,
tunnel transport through a molecule, single molecule logic gate, atomic
scale circuits, atomic scale electronics interconnects and single
molecule-mechanical machines. With its 1991 IBM France Prize, 1997
Feynman Prize, 1999 French Nanotechnology prize, 2001 CNRS Silver Medal
in Chemistry, 2005 Feynman Prize, he made its entry in the 2011 Guinness
for the smallest functioning molecule-gear. He got a European star in
2015 for the coordination of the AtMol project. He is at the origin and
the editor of the Springer Series "Advances in Atom and Single Molecule
Machines" with 11 volumes published since 2012. His book: "Nanosciences,
the invisible revolution" (Le Seuil (2008), World Scientific (2009)) is
describing the history of nanosciences and its political drawbacks to a
general public. He is also a permanent member of the Toulouse Academy of
"Sciences & Belles Lettres".
