A catalytic synthesis of ultrahard fullerite

Pressure of ultrahard fullerite synthesis is decreased by a factor of 2 in the presence of a catalyst. Thus, pressure decreases from 18 to 6-7 GPa under conditions of large plastic deformation at room temperature; upon temperature increasing the synthesis pressure further decreases.

Nanostructured and modifi ed by fullerene C₆₀ metals

A theoretical shear-strength limit for nanostructured and modified by C60 aluminum is achieved. Example: The dependence of hardness of nanostructured and modified by C60 aluminum upon grain size. Maximal hardness H of Al-C60 is 7 GPa which appropriates to yield stress τ* ≈ 0.33 H ≈ 2 GPa. The theoretical shear-strength limit of aluminum is τ*theor ≈ G/(10-15) ≈ 2 GPa also (shear module of aluminum G = 27 GPa)

Nanostructured and modified by carbon nanoclusters thermoelectric materials based on Bi₂Te₃ and Si-Ge

• Synthesized nanocomposites consists of nanocrystals of thermoelectric material covered by layers of C₆₀ molecules or other carbon nanoclusters show high figure of merit (ZT) values.
• The carbon layers in the composites prevent recrystallization of nanocrystals during sintering.
• Discovery of a modulation of electron transport properties (Seebeck coefficient S, electrical conductivity σ, mobility μ) by quantum confinement effect.
• Figure of merit ZT = S2σT/k increases by 20% as a result of independent variation of the parameters S, σ, k in the nanocomposites.
