Twisting Graphene Nanoribbons into Carbon Nanotubes
O. O. Kit, T. Tallinen, L. Mahadevan +2
Although carbon nanotubes consist of honeycomb carbon, they have never been fabricated from graphene directly. Here, it is shown by quantum molecular-dynamics simulations and class…
Scaling of many-particle correlations in a dissipative sandpile
N. M. Bogoliubov, A. G. Pronko, J. Timonen
The two dimensional directed sandpile with dissipation is transformed into a (1+1) dimensional problem with discrete space and continuous `time'. The master equation for the condit…
Impalement transitions in droplets impacting microstructured superhydrophobic surfaces
J. Hyväluoma, J. Timonen
Liquid droplets impacting a superhydrophobic surface decorated with micro-scale posts often bounce off the surface. However, by decreasing the impact velocity droplets may land on…
Brittle fracture down to femto-Joules - and below
J. Astrom, P. Di Stefano, F. Proebst +2
We analyze large sets of energy-release data created by stress-induced brittle fracture in a pure sapphire crystal at close to zero temperature where stochastic fluctuations are mi…
Crumpling of a stiff tethered membrane
J. A. Astrom, J. Timonen, Mikko Karttunen
first-principles numerical simulation model for crumpling of a stiff tethered membrane is introduced. In our model membranes, wrinkles, ridge formation, ridge collapse, as well as…
Effect of a columnar defect on the shape of slow-combustion fronts
M. Myllys, J. Maunuksela, J. Merikoski +4
We report experimental results for the behavior of slow-combustion fronts in the presence of a columnar defect with excess or reduced driving, and compare them with those of mean-f…
