Coumarin-based fluorescent sensors have become popular for its particular structure.
Fluorescence emission spectra of CFe1 (5 μM) / Fe3+ (30 equiv.) and CFe1 (5 μM, pH 3.17) in Tris-HCl ( 0.02M ) solution (methanol/water =95/5, v/v, pH= 7.4). λ ex=470nm It is generally understood that chelating groups C=N, C=S and C=O exhibit a high affinity to transition metal cations, but less binding affinity toward alkali metal and alkaline earth metal cations due to the difference of electronic structure.
Conclusions A novel coumarin-based fluorescent sensor CFe1 was designed and synthesized by means of coupling coumarin aldehyde 3 with thiocarbazide to form Schiff base structure.

In recent years, carbon nanotubes have been applied to analytical chemistry fields in a form of solid due to the specific properties [4~11].
With the specific structure and electronic properties, CNTs has been applied to the electrochemistry since 1996 [4,5].
It may be because of c-CNTs can maintain its conjugate structure of the wall, so DBONBF could connected onto the wall by the π-π effect (Scheme1).
It is speculated that DBONPF attached to the c-CNTs wall through π- stacking, extending the conjugated structure of c-CNTs, resulting in the peak of -C=C stretching modes more intense.

The crystal structure of recast material is different from the base material, so their ability to resist etching should be different as well.
According to the knowledge of physical chemistry and previous studies on chemical etching, a kind of chemical solution which has its main etching effect on recast layer is confected.
But from beginning to end, the metallographic structure on the sample surface hasn’t been damaged apparently, implying that this chemical solution has the function to eliminate recast layer while protect the base material.

The figure shows that the industrial silica sol forms aggregated structures of homogeneous spherical particles of 20-30 nm.
Electron diffraction patterns obtained from such particles indicate a lack of crystal structures of the latter (coagulated silica).
Heating causes profound alterations in the structure of clay substance, which are initially caused by water releasing, and then by its recrystallization occured in the solid phase.
