In order to meet the growing demands for advanced nanomaterials possessing new functions within the International Center for Materials Nanoarchitectonics (MANA), the Group is focused on detailed studies of atomic structures, physical, chemical, mechanical and thermal properties of C and BN nanotubes, and a wide variety of inorganic nanostructures using state-of-the-art microscopy facilities and techniques. Based on fundamental findings the prototype routes towards practical applications of novel nanotubes are developed, such as field-effect transistors, nanomagnets, piezosensors, nanocables, field-emitters, small-mass conveyers, electrical switches and temperature sensors.


Stepwise absorption of carbon multi-walled nanotube inner shell packages by a tungsten electrode under Joule heating of the carbon tube/metal electrode interface in the STM-TEM holder. These results were reported by us in Jan. 2010; Adv. Mater. 22, 93 (2010).

  Melting/decomposition of an individual boron nitride nanotube under biasing to 140 V in the STM-TEM holder. Amorphous Boron ball growth on the tube surface preceding its sudden “explosion”-like destruction is evident. These results were reported by us in June 2009; Nano Lett. 9, 2251 (2009).

Stretching of a 3-branch soldered carbon nanotube network using AFM-TEM holder. The central Co-clamp displays extreme robustness with a breaking strength of 1-5 GPa The process of clamp creation involves in-tandem Joule heating and electron irradiation of two crossed tubes with a filled Co particle in one of them. These results were reported by us in Dec. 2009; Adv. Mater. 21, 4477 (2009); Cover Image Paper.
