By utilizing buckling, which is a phenomenon that a structure under loading becomes unstable resulting in a sudden change in its shape, it may be possible to realize novel nanoscale devices that convert mechanical input to some different forms of output (i.e. the abovementioned functional aspects).
To investigate the mechanical properties and deformation behavior of nanostructured materials, atomistic modeling simulations such as molecular dynamics (MD) are usually employed.
The localization of the instability mode vectors implies that the nanotube loses mechanical stiffness in the vicinity of the Stone-Wales defect under a large compressive stress.
Since these factors are likely to affect the behavior of instability modes, further analyses are under way for more in-depth understanding of the buckling mechanism.

In recent years, compared with LCD, OLED flat-panel display and plasma display, the advantages of flexible displays have become increasingly prominent, because of its ultra-thin, light weight, durable, large storage capacity, the design freedom, crooked, winded and impact resistance and other properties[1-2].
The processing quality and precision of ultra-thin stainless steel will directly affect the performance of the device [8].

These factors influence the speed and uniformity of the filtration process.
This study provides a foundation for further exploration into the impact of the shape and geometric parameters of filter boxes on the protective and ergonomic properties of respirators [23].
However, structural factors still present considerable difficulties in analysis.

Introduction The grain, grain boundary and unit of ceramic micro-structure are in the level of micro-dimension, because its grain is fined, and the number of grain boundary increases greatly, material strength, hardness and super-plastic may be improved, which has important influence on its properties such as mechanics, electrics, optics, calorifics, magnetics and etc..
Al2O3 powder is used as coating material, and 40Cr as substrate, its coating is re-melted by CO2 laser, and residual stresses of Al2O3 coating are measured, and the effected factors of residual stress are discussed, and the forming reasons of residual stress and strengthening mechanism are analyzed.
When the time of laser thermal action is long, the grain is growed up easily, and caloric dispersion also needs longer time, more longer the time of caloric staying, more bigger the heat-affected zone, its hardness is relatively lower.

Given that corrosion is causing considerable financial costs of reconstruction, whether in infrastructure, construction, mechanical engineering or monuments, and it also causes failure and reduces the reliability of the structural components, which can lead to serious consequences of various kinds of property damage to loss of life, it is good to know the atmospheric environment in which the exposed material will be used in order to eliminate the possible economic consequences [2, 3].
The key factors of this standard are temperature, humidity, sulfur dioxide pollution and salinity [4].
On the other hand, the results may be affected by a lower number of measuring stations of SHMU.
An important factor in Eq. 1 is chlorides, but there are only 5 stations measuring this parameter.
The main factors obtained in this standard STN EN ISO 9223 could be based on the dose-response function uncertainty or by measurements of air pollution and climatic data.
