Atomically and Molecularly-Organized Catalytic Surface Science

Molecularly and atomically thin semiconductor and carbon nanoshells

Approaches to the formation of molecularly and atomically thin solid shells based on the transformation of thin planar films into more functional 3D precise shells are outlined. In the overview part of the present work several examples are given illustrating the possibility to obtain in bent films new effects never observed in planar films and to fabricate new nanomaterials from highly – ordere...

Science as organized scepticism.

Real progress in understanding how the natural world works only truly began with the Enlightenment, with its guiding principle that the truth is to be found not by appeal to authority but by experimental tests and evidence. Unfortunately, but understandably, science is too often seen--in school, in university and especially on quiz shows--as certainty. In fact, science (including social science...

Surface patterning by atomically-controller chemical forces: molecular dynamics simulations

The use of atomi~ly-controlled reactive chemical forces via modified sca~~g-probe microscope tips provides a potentially powerful way of building nanodevices. In this work, we use atomistic simulations to explore the feasibility of one such system, namely the selective abs~action of hydrogen from a diamond surface using a tip with a chemisorbed ethynyl radical. We characterize reaction rates an...

Surface science and catalysis.

During the last 20 years, surface scientists have developed a variety of techniques that make it possible to study, on the molecular level, the structure, composition, and chemical bonding in the surface monolayer. Both single-crystal model catalysts and real catalyst systems that are active in important chemical processes have been investigated by a combination of ultrahigh-vacuum surface scie...
