A number of studies on 1,8-naphthyridine rings have shown that the N atoms in these compounds can effectively bind with transition metal ions and the nitrogenous bases of DNA through hydrogen bonding, so 1,8-naphthyridyl derivatives may find use in fluorescent materials, medicinal chemistry and biological fields[2][3].
The structure was fully characterized by multinuclear NMR spectroscopy, mass spectroscopy and elemental analyses.
The structured low-energy absorption bands has a large extinction coefficient (∼1.5×104 mol-1•dm-3•cm-1).

X-ray diffraction characterized results showed that the structure of the (Ba0.88Ca0.12)( Zr0.12Ti0.88)O3 powders was perovskite structure and the particle size was approximately 37nm.
The crystal structures of (Ba0.88Ca0.12)( Ti0.88Zr0.12)O3 powders and ceramics were determined by X-ray diffraction (XRD).
It can be seen that all the peaks corresponding to the perovskite structure.

The addition of boron compound promotes the thermostability of resin by improving the crosslinked structure.
That was due to the change structure of the resin from linear structure to net structure.
In the net structure, the B atom formed a B-O bond, which made aromatic ring and resin connected with a six-circular ring (-O-B-O-C-).

Introduction Because metal Ni-based coatings can not only have better performance in mechanical and magnetic, but also have steady chemistry property, it has been applied wildly in many kinds of field such as electric-found and micro-electronics industry.
In a pulse period, as electric current put through, electric chemistry polarization was increased and the coatings of more compact, uniform and refined crystals were formed on account of metal ion deposited adequately round cathode.
The pulse electroforming can improved physics and chemistry property of coatings by using of voltage and electric current vibrating, which can increase electric chemistry polarization and decrease concentration polarization round cathode.
The frictional pair was structured by fixation ring and rotating steel ring.
