Purpose: To compare the effect of different treating agents on the shear bond strength (SBS) between zirconia and orthodontic brackets.
Methods: Fifty zirconia specimens were randomly divided into 5 groups(n=10), and treated with sandblasted and 37% phosphoric acid.Group A was control sample without any treatment; Group B was treated with silane coupling agent; Group C was treated with silane coupling agent and SE Bond; Group D were treated with Z-Prime(TM) Plus; Group E were treated with Z-Prime(TM) Plus+SE Bond.
[Study on synthesis and photoluminescence of the complexes of rare earth Eu(III) with 4-vinyl pyridine copolymer].

Department of Chemsical Engineering, North China Institute of Technology, Taiyuan 030051, China.
Rare earth (Eu)-polymer ternary complexes were synthesized using copolymer of 4-vinyl pyridine-methyl acrylate as ligand, and using phen and bipy as coordination ligand. The compositions of the complexes were characterized by FTIR and elemental analysis. The photophysical process of photoluminescence of the complexes were characterized by FTIR and elemental analysis.
