Icing, fogging, and frosting cause safety hazards, reduced energy efficiency, operation difficulties in various sectors including aerospace renewable energy. Traditional methods for mitigating these hazards are often based on active transducers that either inconvenient, intensive, or utilizing chemicals detrimental to the environment lacking long-term stability. To tackle challenges of situ monitoring fogging icing structural surfaces, we explored an integrated platform by combining...

First principles density functional calculations are used to study the uniaxial strain effects on energy band structures of single- and multi-walled boron nitride nanotubes. Simulation results show that tensile induces a slight decrease in gaps, while small large compressive strains induce increases decreases respectively. The maximum change gap is ~0.5 eV. all nanotubes not sensitive strain, which means could be blue UV light-emitting devices under strain.

Molecular dynamics simulations with Tersoff potentials were used to study the tensile and compressive mechanical behavior of SiC nanowires torsion strain. The simulation results show that small strain does not affect nanowires. However, large induces decrease critical stress. With strain, collapse occurs in before failure buckling, deformation zone collapsed part.

The mean-field expressions derived from the transverse Ising model are used to investigate second-order ferroelectric phase transition. With this theory, properties of thin films formed by inserting a monolayer material B into A in middle was studied. Firstly, recursive equation for transition film with one distinct inserting-layer obtained. Next, effect exchange interaction and field parameters materials on diagrams investigated. results show that modification parameter values B,...

Simulations have been carried out on [001]-oriented Ni 3 Al nanowires with square cross-section the purpose to investigate mechanism of failure under tensile and compressive strain. Simulation results show that elastic limit nanowire is up about 15% strain yield stress 5.99–6.48 GPa Under stage, deformation mainly through uniform elongation bonds between atoms. With more strain, slips in {111} planes occur accommodate applied at room temperature And by forming twins within nanowires.

The melting behavior of Ni 3 Al alloys in one, two and three dimensions were studied by adopting molecular dynamics simulations with many-body interatomic potentials. results simulation show that temperatures the nanowires nanofilms rise increase size nanostructures to a saturation value, finally reach proximate temperature bulk . also reveal begin melt at surface, then it rapidly extends interior as increase. large surface-to-volume ratio may account for decreased observed present simulations.
