Fourier transform infrared spectrometer (GX-1, Perkin Elmer, USA) was employed to examine the chemical structure of CSR.
The dried raw sample had some dent structure but also remained a relatively dense surface.
Compare to the original sample, the IL-treated sample was endowed with looser structure.

Keywords: salicyloyl hydrazone derivatives, cytotoxic activity, structure–activity relationships
Abstract.
Their structures were characterized by melting point, 1H-NMR, ESI-MS and elemental analyses.
However, there are few publications about their cytotoxic activity and structure-effect relationships.
On the basis of the experimental data, structure-effect relationships were discussed.
All of the products gave satisfactory analytical and spectroscopic data, which were in the full accordance with their depicted structures.

Abstract.
The newly determined corrected C factors, C = 0.06 for the cubic structures and C = 0.11 for the hexagonal structures, were used in the Kozeny-Carman model to determine the permeabilities of these structures.
In particular the cubic structure showed permeability values ranging from 1× 10-8 m2 to 2× 10-9 m2 for these structures.
The permeability depends on the surface area of the whole structure, on the material surface, the internal structure, and on the applied flow fluid.

Finally, flower-like TiO2 hierarchical structures with a diameter of 2 ~ 2.3 μm are assembled by these petal-like structures.
The electrochemical properties of the flower-like TiO2 hierarchical structures were studied by using these hierarchical structures as the anode material in a lithium-ion battery.

Etching chemistry was HF 0.5% at 30°C.
shows an etch profile of two ONO structures, the first one with an annealed LPCVD top oxide and the second one with thermal top oxide, obtained by in-situ steam oxidation of the nitride.

In this case two etching chemistries were used for profiling: HF 0.3% and a highly diluted BOE mixture.
Indeed, after the annealing treatment the etching rate becomes so low that it requires a different etching chemistry.
