Thermomechanical Stability of Carbyne-Based Nanodevices
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...
متن کاملThermal stability of idealized folded carbyne loops
Self-unfolding items provide a practical convenience, wherein ring-like frames are contorted into a state of equilibrium and subsequently pop up' or deploy when perturbed from a folded structure. Can the same process be exploited at the molecular scale? At the limiting scale is a closed chain of single atoms, used here to investigate the limits of stability of such folded ring structures via f...
متن کاملToward carbyne: Synthesis and stability of really long polyynes*
Molecules composed of sp-hybridized carbon chains (polyynes) are the simplest of the known conjugated organic oligomers. In comparison to their counterparts such as polyacetylene and polydiacetylene, however, the formation of polyynes has traditionally posed a difficult synthetic challenge. In particular, there is no reliable method to form end-capped polyethynylene, and monodisperse polyynes h...
متن کاملEnzyme-Operated DNA-Based Nanodevices
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...
متن کاملTowards autonomous DNA-based nanodevices
Molecular recognition, programmability, self-assembling capabilites and biocompatibility are unique features of DNA. The basic approach of DNA nanotechnology is to exploit these properties in order to fabricate novel materials and structures on the nanometer scale. This cumulative dissertation deals with three aspects of this young research area: fast analysis, autonomous control of functional ...
