Biography

The creation of useful substances, and finding new ways of using existing ones, are at the heart of the modern science and technology evolution. Continued scientific advancement of new materials is essential for the global development of an ecologically clean environment, renewable energy sources, and ultimately, a better quality of life.

Computational Nanoscientist, Fedor Naumkin, PhD, Associate Professor of Chemistry in the Faculty of Science, has spent nearly three decades developing molecular systems to guide scientific advancement. His research program concentrates on predicting new stable structures and compositions; investigating relationships between various properties; and ultimately, designing systems with desirable characteristics. Practical applications include the development of new materials with unique properties, novel catalytic agents, elements of molecular electronics and machinery, molecular storage and transport, and energy storage at the molecular level.

A Project Leader of UOIT's Collaborative Laboratory for Applied and Interdisciplinary Mathematics (CLAIM), Dr. Naumkin's latest work focuses on modelling novel molecular systems and processes in order inspire and guide experiments. These systems are anticipated to have various useful properties such as high sensitivity to light, yielding efficient detection, and highly efficient storage of energy at molecular levels; increased polarity facilitating the development of novel stable aggregates of molecules up to materials, and to leading to a new types of chemical reactions.

Drawn to its interdisciplinary nature, Dr. Naumkin joined UOIT in 2004 as an Assistant Professor and was appointed to his current role in 2009. His previous international experience includes Visiting Assistant Professor in the Department of Chemistry at the University of Toronto; INTAS Visiting Researcher in the Department of Chemistry, University of Cambridge, England; MPI Visiting Scientist in the Institute of Theoretical Chemistry, University of Stuttgart, Germany; Royal Society post-doctoral fellow in the School of Chemistry at the University of Sussex, England; and Senior Research Associate in the General Physics Institute at the Russian Academy of Science. Dr. Naumkin received his Master of Science in Physics (Honours) from Moscow State Engineering Physics Institute, and his Doctorate in Laser Physics (Theoretical) from the General Physics Institute (RAS) in Moscow, Russia.

Reshaping and Linking of Molecules in Ion-Pair Traps Chemical Physics Letters

2016-01-01

A series of insertion complexes of small molecules trapped between alkali-halide counter-ions are investigated ab initio. The molecular shape is altered inside the complexes and varies in corresponding anions. Stabilities and charge distributions are investigated. Strong charge-transfer in the alkali-halide component effectively through the almost neutral molecule results in very large dipole moments. The most stable species is used to construct a dimer significantly bound via dipole–dipole interaction. Another complex with two alkali-halide diatoms trapping the molecule represents a unit of corresponding longer oligomer. This completes the array of systems with the molecule effectively in ion-pair, ion-dipole, dipole-pair electric fields.

Computational Cogitation of Cn@ Al12 Clusters ChemPhysChem

2014-10-05

A variety of novel CnAl12 core–shell nanoclusters have been investigated using density functional calculations. A series of Cn cores (n=1–4) have been encapsulated by icosahedral Al12, with characteristic physical properties (energetics and stabilities, ionisation energies, electron affinities) calculated for each cluster. Other isomers, with the Cn moiety bound externally to the Al12 shell, have also been studied.

A Computational Study of ‘Al-Kanes’ and ‘Al-Kenes’ Physical Chemistry Chemical Physics

2013-12-18

Two novel series of ‘Al-kanes’ (CnAl2n+2) and ‘Al-kenes’ (CnAl2n) have been studied theoretically in order to shed light on their structure, stability and properties. Density functional calculations suggest that the structures tend to be dictated by the constituent aluminium atoms, rather than the carbon backbone. This is the net effect of the aluminiums attempting to adopt preferred close-packed structures. Calculated energetics suggest a special stability of clusters with n(C) = 2 and 4 in both series and plausible interpretations are suggested.

Small Metal–Organic Molecular Sandwiches: Versatile Units for Induced Structure Manipulation Chemical Physics Letters

2013-12-18

Interfaces between metal atoms and organic molecules are key units of many important metal–organic systems. Presented are results of ab initio calculations for a series of complexes of 2nd-row metal atoms sandwiched between small unsaturated hydrocarbon molecules. Evolution of the system structure and stability is studied for different metal atoms, as well as upon excitation, ionization and electron attachment. Predicted interesting features include cooperative stabilization, unusual geometries, reversible charge- or excitation-governed geometry alterations. The observed variety of properties suggests potential applications of such species as intermolecular junctions and units with charge- or spin-controlled shapes in molecular devices and/or machines.

Book Chapter: Hydrogen in Light-Metal Cage Assemblies: Towards a Nanofoam Storage Progress in Theoretical Chemistry and Physics: Advances in Quantum Methods and Applications in Chemistry, Physics, and Biology

2013-01-01

Isomeric alternatives to usual metal-hydrides as hydrogen-storage materials are considered. Presented are results of ab initio calculations for Be n (n≤18) clusters with up to two endohedral H2 molecules which undergo in-cage dissociation. The systems structures and stabilities are discussed, including energy barriers for hydrogen exit from the cage. The origin of the observed metastability, allowing for a lower-temperature release of H2, is explored. Preservation of the cage integrity and hydrogen confinement is investigated when such core-shell units are merged into larger assemblies structurally resembling fragments of hydrogen-filled metal nanofoams, possible isomeric forms of metal-hydride solid. Different “nanofoam” isomers are composed of pairs or single H atoms suspended electrostatically inside the metal cage units (“nanobubbles”). Interesting features include simultaneous exit of two H atoms, etc. Structural extrapolations suggest potential hydrogen storage capacity up to ∼10 weight-%.

2011-01-01

Nanoscience is one of the most exciting areas of modern physical science as it encompasses a range of techniques rather than a single discipline. It stretches across the whole spectrum of science including: medicine and health, physics, engineering and chemistry. Providing a deep understanding of the behaviour of matter at the scale of individual atoms and molecules, it provides a crucial step towards future applications of nanotechnology. The remarkable improvements in both theoretical methods and computational techniques make it possible for modern computational nanoscience to achieve a new level of chemical accuracy. It is now a discipline capable of leading and guiding experimental efforts rather than just following others. Computational Nanoscience addresses modern challenges in computational science, within the context of the rapidly evolving field of nanotechnology.
