The mixture was sealed in a 100 mL Teflon-lined autoclave and was heated at 150 °C and maintained for 20 min under the temperature-controlled mode of an MDS-8 microwave hydrothermal system (Shanghai Sineo Microwave Chemistry Technology Co.
The flower structures that are built up by slightly bending flakes began to form.
From Fig.2, it can be concluded that all these CuS structures are constructed by nanoflakes.
The red shift of the maximum may be associated with the formation of the novel assembled CuS microsphere structure.

Their results show that the modification can effectively change the band gap structure of TiO2 and improve the photocatalytic performance further.
The phase structures were tested by D8ADVANCE X-ray diffractometer.
When the calcination temperature is 600°C, the amorphous structure of TiO2 samples almost transform into anatase structure completely.

Both texture and chemistry are important in battery operation for powdered LixCoO2.
The valence electronic structure formed by the transition metal and oxygen ions is flexible, so the variation in Li concentration with charging is possible.
A metal-insulator transition occurs in two crystallographically identical hexagonal structures (Chapter 2 of [1]).  
The synthesis of LiCoO2 at high temperatures (referred to as HT-LiCoO2 ) [3], [4] results in the ideal layered α - NaFeO2 -type or O3 structure (R3¯ m (166)) space group with an ABCABC stacking of layers, while low temperature (LT) synthesis results in the spinel structure (Chapter 1 of [1]) [4].

Pillared layered materials (PLMs) are another important class of porous materials, which have a special two-dimensional pore structure and a higher thermal stability [6,7,8].
The pore structure of PLMs can be controlled regularly with the variations of layer distance and the distribution of metal oxide pillars in interlayer space [9].
And the structure of one layered board is represented by a talc lamella here [14].
The adsorption of n-pentane, which reflects the characteristics of the special pore structure of PLMs, are also similar to the adsorption of fluids in zeolites [3,19].

This sensor can be applied in the many fields, i.e. physics, chemistry, biology, biochemistry, medical, and environment.
Such sensor has potential toreplace many conventional sensor systems because of a relatively low cost of production, high sensitive, rapid response, and a reduced size of the active area (typically 10-6 cm²) [1-3].Moreover, the microcantilever sensor has been applied in the fields of environment, medicine, chemistry, physics, and biology.
However, such method has a complex device structure which is still a major limitation in miniaturized humidity sensors for real-life applications.

., chemistry and physics) and/or life sciences (e.g., biology, microbiology and biochemistry) together with mathematics and economics to processes that convert raw materials or chemicals into more useful or valuable forms.
This relatively new scientific field investigates the relationship between the structure of materials at atomic or molecular scales and their macroscopic properties.
It incorporates elements of applied physics and chemistry.

The presence of symmetrical hydroxyl groups in the structure of the obtained compounds makes them suitable as chain extenders of low molecular weight diisocyanate prepolymers.
