An approach is developed to predict stability of carbyne-based nanodevices. Within this approach, the thermo-fluctuation model of instability and break of contact bond in nanodevices, containing carbyne chains and graphene sheets, is offered. Unlike the conventional models, it does not include empirical constants. The results of DFT calculations are used as initial data for this model. Possibil...

Functional molecular nanodevices and nanomachines have attracted a growing interest for their potential use in life science and nanomedicine. In particular, due to their versatility and modularity DNA-based nanodevices appear extremely promising. However, a limitation of such devices is represented by the limited number of molecular stimuli and cues that can be used to control and regulate thei...

One of the most important physical parameters to describe the quality of a piece of semiconductor material is the electron scattering length le. Also referred to as the mean-free path, it stands for the average distance between the randomly distributed scatterers in the material, such as lattice defects, impurities, and phonons. The electron mean-free path is typically a few nanometers (1 nm = ...

333 converted into homozygous parental breeding lines, as desirable allele combinations are lost through recombination during meiosis. That obstacle has been overcome by Wijnker et al. who have reverse bred Arabidopsis thaliana parental lines from heterozygous hybrids using a process that involves preventing meiotic crossing over. The authors used RNA interference (RNAi) to silence DISRUPTED ME...

Advances in nanotechnology have made it possible to assemble nanostructures into a wide range of micrometer-scale sensors, actuators, and other novel devices... and to place thousands of such devices on a single chip. Most of these devices can benefit from intelligent control, but the control often requires full programmability for each device’s controller. Routing thousands of signals off-chip...
