According to XRD data, the phase composition of ZrO2(Y2O3) was presented by high-temperature tetragonal and low-temperature monoclinic modifications of ZrO2.
A restoration of geometric shapes of micro- and nanocrystals and their symmetry occurs; a higher degree of uniformity and a reduction of anisotropy of magnetic properties are observed as well.

Banik et al. [7] investigated the flexural creep behavior of Polypropylene composites in the range of temperatures varies between 20 °C to 80°C, a great agreement was seen between the resultant data and Findley power law model results.
Moreover, a broad reduction in creep-rupture resistance happened with increasing temperature especially for unreinforced PA66 and that attributed to the fact of any increase in applied temperature higher than Tg will be increased the mobility of molecular chains and finally results a high deformation level, while with the presence of reinforcement materials, the molecular chains were restricted and the composite appeared a high resistance against deformation.

The data obtained allow us to assert that the addition of a nanodispersed fraction in an amount of 0.5 wt.% leads to an increase in the relative density of the sintered products and does not depend on the sintering method.

The increase uses of wood products in construction can lead to constant reduction in general effects on the environment, especially to reduce GHG (greenhouse gas) associated with the construction process.
Through rigorous scientific methods, lots of indices data of the two houses have been analyzed and compared, including total amount of heat supply, average energy consumption, hourly indoor and outdoor air temperatures and relative humidity values, building heat-storage capacity, heat-transfer coefficient of envelope structure, inner surface temperature distribution on thermal bridges in building enclosure structure and etc..
