DOI: 10.1002/admi.201400493 wavelength and amplitude ( Figure 1 a). Further increase in the strain level triggered the transition from wrinkles to folds, creating well-defi ned closed channels with a diameter in the nanoscale range (Figure 1 b). The characteristic dimensions of the channels such as wavelength, amplitude, and diameter were robustly tunable by changing the duration of oxygen plas...

in this research, a semi empirical approach has been suggested for calculating the activation energyof unimolecular thermal decomposition of vinyl ethers yielding saturated products. the calculationprocedure is based on the use of molecular mechanics (mm) methods. these methods which involvethe construction of the transition state for a molecule mainly consider the formation of a “hydrogenbridg...

It is widely assumed that the ability of Candida albicans to switch between different morphologies is required for pathogenesis. However, most virulence studies have used mutants that are permanently locked into either the yeast or filamentous forms which are avirulent but unsuitable for discerning the role of morphogenetic conversions at the various stages of the infectious process. We have co...

Large-strain monotonic and cyclic loading tests of AZ31B magnesium alloy sheets were performed with a newly developed testing system, at different temperatures, ranging from room temperature to 250 °C. Behaviors showing significant twinning during initial in-plane compression and untwinning in subsequent tension at and slightly above room temperature were recorded. Strong yielding asymmetry and...

Correlated electron materials can undergo a variety of phase transitions, including superconductivity, the metal-insulator transition and colossal magnetoresistance. Moreover, multiple physical phases or domains with dimensions of nanometres to micrometres can coexist in these materials at temperatures where a pure phase is expected. Making use of the properties of correlated electron materials...

Strain is ubiquitous in solid-state materials, but despite its fundamental importance and technological relevance, leveraging externally applied strain to gain control over material properties still infancy. In particular, the diverse phase transitions topological states two-dimensional (2D) transition metal dichalcogenides (TMDs) remains an open challenge. Here, we exploit uniaxial stabilize l...

The structural, magnetic, and electronic properties of (STO)4/(YTO)2 superlattice consisting of Mott insulator YTiO3 (YTO) and band insulator SrTiO3 (STO) under strain are investigated by the density-functional-theory plus U method. It is found that an insulator-metal transition occurs when a compressive strain of 0.2% is applied. The structural analyses reveal that the presence of metallic sta...

We perform single-molecule DNA experiments to investigate the relaxation dynamics of knotted polymers and examine the steady-state behavior of knotted polymers in elongational fields. The occurrence of a knot reduces the relaxation time of a molecule and leads to a shift in the molecule's coil-stretch transition to larger strain rates. We measure chain extension and extension fluctuations as a ...

Abstract Topological materials host robust properties, unaffected by microscopic perturbations, owing to the global topological properties of bulk electron system. Materials in which invariant can be changed easily tuning external parameters are especially sought after. Zirconium pentatelluride (ZrTe 5 ) is one a few experimentally available that reside close boundary phase transition, allowing...

We show, through the use of Landauer-Büttiker (LB) formalism and a tight-binding (TB) model, that transport gap twinned graphene can be tuned application uniaxial strain in direction normal to twin band. Remarkably, we find Egap bears square-root dependence on control parameter ϵx−ϵc, where ϵx is applied ϵc∼19% critical strain. interpret this as evidence criticality underlying continuous phase ...
