Transport of fullerene molecules along graphene nanoribbons

We study the motion of C₆₀ fullerene molecules and short-length carbon nanotubes on graphene nanoribbons. We reveal that the character of the motion of C₆₀ depends on temperature: for T < 150 K the main type of motion is sliding along the surface, but for higher temperatures the sliding is replaced by rocking and rolling. Modeling of the buckyball with an included metal ion demonstrates that th...

INTERACTION OF PROTEINS WITH SMALL MOLECULES

Controlling protein transport by small molecules.

Many proteins are transported from the nucleus to the cytoplasm by the exportin CRM1, which recognizes cargo proteins through a leucine rich nuclear export signal (NES). This nuclear export process can be inhibited by several small molecules, both natural products and fully synthetic compounds. The structural basis for the inhibition of nuclear export by leptomycin (LMB) based on disruption of ...

Applications of Small Molecules in Muscle Tissue Engineering

Introduction: Skeletal muscles account for about 40% of the total body weight. Every year, hundreds of people lose at least part of their muscle tissue due to illness, war, and accidents. This can lead to disruption of activities such as breathing, movement, and social life. To this end, various therapeutic strategies such as medication therapy, cell therapy and tissue transplantation have been...

Black hole evaporation along macroscopic strings.

We develop the quantization of a macroscopic string which extends radially from a Schwarzschild black hole. The Hawking process excites a thermal bath of string modes that causes the black hole to lose mass. The resulting typical string configuration is a random walk in the angular coordinates. We show that the energy flux in string excitations is approximately that of spacetime field modes. Th...
