Organic EL devices, or organic light-emitting diodes, are mainly composed of emission materials, hole-transporting materials and electron-transporting materials.
A number of emission materials and hole-transporting materials were reported.
In contrast, materials for electron-transporting materials are only a few [4].

This article deals with using recycled concrete in cement-based composite materials.
Introduction Increasing amount of construction waste, cost reduction of building materials and reduction of non-renewable resources consumption require more frequent use of recycled materials in construction [1].
Better sorting and good knowledge of the source material provide more efficient applications to new building materials.
Based on grain size and specific surface area results of FGRC and cement it can be assumed, that both materials were milled at a similar level.

The choice of similar materials and the design of mix proportions is a key step in landslide model test.
On the basis of experiment, we conduct a research for the similar materials which may sufficing volume weight, cohesive force, angle of internal friction, deformation modulus, and the infiltration coefficient on the same time.
Based on the predecessors' experience ,this paper conducts an exploration research on the new mix proportion of similar materials which satisfy the similarity of the deformation, destruction, and infiltration ( i.e, volume weight, deformation modulus, cohesive force, angle of internal friction and infiltration coefficient are all similar) to meet the practical landslide model test requirements. 2 Choices of Similar Materials and Schemes of Mix Proportion The landslide model test is based on the similarity between model and prototype.
According to the principles above and the overall requirements of the landslide similar materials, which is a kind of high volume weight, low cohesive force, low deformation modulus, low infiltration coefficient and the right angle of internal friction granular materials, I successively explores two sets of similar material test plan. 3 The First Set of Similar Material Test Plan The first kind of similar material is the mix of high-strength glass micro beads and talcum powder. 3.1 Physical Properties of the Similar Material High-strength glass micro beads are the primary counterweight material.

This shape of isotherm characterizes them as materials having also a slit porosity.
As shown by porometry and XRD, undopedsemiamorphous materials have hollandite/ramsdellite domains intergrowth with sizes of coherent scattering regions less than 20-50 Å.

Determination of Mechanical Properties of Metallic Materials from Very Small Volumes by Means of Small Punch Test DYMÁČEK Petr1,2,a*, DOBEŠ Ferdinand1, b and KLOC Luboš1,c 1Institute of Physics of Materials, Academy of Sciences of the Czech Republic, Žižkova 22, 616 62 Brno, Czech Republic 2CEITEC – IPM, Žižkova 22, 616 62 Brno, Czech Republic apdymacek@ipm.cz, bdobes@ipm.cz, ckloc@ipm.cz * corresponding author Keywords: Small punch test, uniaxial test, creep, stress relaxation Abstract.
The paper summarizes capabilities of the small punch tests on miniature disc specimens from metallic materials.
Initially developed as a ranking test for evaluation of irradiated materials [2] it has gained an important role in the domains where the material is not available in suitable amount or exposed material needs to be tested from components that are still in operation [3].
