Materials The composition of studied renders is shown in Table 1 (w/d is the water to dry substances ratio by mass).
All studied materials had higher bending strength than the reference lime render R1.
As they also had the highest specific heat capacity their thermal diffusivity was lowest among the studied materials.

Introduction Titanium and its alloys are widely used as materials for permanent implants in orthopedics and dentistry.
To enhance bone bonding coatings with bioactive materials, such as HA, are developed.
The development of bioceramics becomes of great importance for bone replacement, repair or reconstruction – the population shows an increased ageing and a high diseases occurrence and new materials are needed to overcome the shortcomings of the current ones [3].
Materials and methods A Ti6Al4V bar with 24mm in diameter was cut with a metallographic cutter to obtain 1mm thick disks.

Due to the different thermophysical characteristics of the materials, such systems experience large thermal loads, especially in high-power semiconductor devices, which can lead to contact melting (CP) in multilayer metallization systems [4, 5].
Materials and Methods The objects of the research were structures of the metal-semiconductor (Al-Si) type.

According the failure criterion of material and adhesive surface, to determined the cracking mechanism and crack control of aerated concrete thermal insulation layer.
the calculation too complex to complete.So in this article a over-lapped model of composite material mechanics is used to construct the model needed in this study，using energy method obtained the solution of the stress between the wall layer in the form of series,compared with the exact solution of the beam on the elastic foudation form the material mechanic,translated the series solution into exact solution. using the equilibrium of the wall.

Microstructures provide the crucial link between solid state flow of rock materials in the laboratory and large-scale tectonic processes in nature.
However, most of our understanding of these processes in olivine comes from tests on coarse-grained materials that show grain size reduction through dynamic recrystallization.
In the case of olivine materials with a relatively large starting grain size grain refinement induces a switch from dominant GSI dislocation to deformation mainly by GSS flow.
In ceramic materials and metals it is often observed that GBS dominated flow is accompanied by dynamic grain growth.
