Can phenyl-propanedione influence Knoop hardness, rate of polymerization and bond strength of resin composite restorations?

William Cunha Brandt et al.

Journal of dentistry, 39(6), 438-447 (2011-04-23)

The aim of this study was to evaluate the degree of conversion (DC), rate of polymerization (R(p)(max)), Knoop hardness (KHN) and bond strength between tooth/restoration of composite resins containing different photo-initiators photo-activated by different light-curing units (LCUs). A mixture of

Direct determination of ephedrine intermediate in a biotransformation reaction using infrared spectroscopy and PLS.

Marcello G Trevisan et al.

Talanta, 75(4), 1021-1027 (2008-07-01)

Fourier transform mid-infrared spectroscopy (FT-MIR) coupled with a homemade attenuated total reflectance (ATR) flow-cell was used for on-line monitoring of a biotransformation reaction. The reaction was also monitored off-line by gas chromatography-mass spectrometry (GC-MS) enabling to establish a multivariate model

Effect of various visible light photoinitiators on the polymerization and color of light-activated resins.

Hiroyuki Arikawa et al.

Dental materials journal, 28(4), 454-460 (2009-09-02)

The purpose of this study was to investigate effects of various visible light photoinitiators on the polymerization efficiency and color of the light-activated resins. Four photoinitiators, including camphorquinone, phenylpropanedione, monoacrylphosphine oxide (TPO), and bisacrylphosphine oxide (Ir819), were used. Each photoinitiator

Effect of co-initiator ratio on the polymer properties of experimental resin composites formulated with camphorquinone and phenyl-propanedione.

Luis Felipe J Schneider et al.

Dental materials : official publication of the Academy of Dental Materials, 25(3), 369-375 (2008-10-14)

To evaluate the effect of amine ratio (ethyl 4-dimethylaminobenzoate, EDMAB) on the maximum rate of polymerization (R(p)(max)), degree of conversion (DC), Knoop hardness (KH), water sorption (Wsp), water solubility (Wsl) and color changes (DeltaE) over time of resin composites formulated

Conformational flexibility, UV-induced decarbonylation, and FTIR spectra of 1-phenyl-1,2 propanedione in solid xenon and in the low temperature amorphous phase.

Susy Lopes et al.

The journal of physical chemistry. A, 109(25), 5560-5570 (2006-07-13)

1-Phenyl-1,2-propanedione has been isolated in low-temperature xenon matrixes and studied by FTIR spectroscopy, supported by DFT(B3LYP)/6-311++G(d,p) calculations. In good agreement with previous electron diffraction data [Shen, Q.; Hagen, K. J. Phys. Chem. 1993, 97, 985], the calculations predicted the existence
