Due to the complex nature of materials and objects, extremely sensitive, spatially resolved, multi-elemental and versatile analytical instruments were needed.
It can be concluded that these techniques in combination are powerful for the investigation of heterogeneous glassy materials.
Quantitative analysis of major, minor and trace elements of archaeological materials is crucial to answer questions associated with manufacturing technology, raw materials, origin, restoration and protective conservation.

The materials were doped into hybrid sol-gel (VTES:TEOS) matrix to form encapsulation material to insert in UV LED chip.
Fig. 2 shows the absorption spectra of Eu(tta)3phen and Tb(4DBBA)3TPPO phosphor materials.
The highest overlapped peak for both Eu(tta)3phen and Tb(4DBBA)3TPPO phosphor materials occurred at 380 nm of wavelength.

The higher order crack tip fields for an anti-plane crack in functionally graded piezoelectric materials (FGPMs) under mechanical and electrical loadings are studied.
The first two items of crack-tip higher order fields of FGPMs have the same mathematical forms as ones of homogeneous piezoelectric materials.

Experimental The materials Li1+xV3O8 were prepared by LiOH, NH4VO3 and C2H5NO2.
The materials Li1+xV3O8 were spreaded on Al foils and dried under vacuum.
Therefore, the materials prepared via this new method show better capacity retention, and the cycle life of the material with a V/C2H5NO2 ratio of 1.0/1.0 remains the best .

Introduction As we know, heterogeneous materials such as rock or rocklike material have a composite or heterogeneous microstructure or texture, which can be seen with the naked eye or with a microscope at various magnifications.
Moreover, the behaviour of rock or rocklike materials and the growth of cracks or microcracks in rock or rocklike materials are strongly influenced by this heterogeneous microstructure.
Consequently, the numerical methods used for studying the fracture behaviour of rock or rocklike materials should take the heterogeneity into consideration.
Sum of elastic energy release (ERE) of the all elements is total elastic energy release of brittle materials occurred at current loading step.
