The degree of conversion of organic matter can be measured by the conversion rate of organic matter in hydrocarbon source rocks in the sequence from low maturity to high maturity, which is usually referred to as the transformation ratio of organic matter— that is, TRHI. ...

The degree of conversion (DC) and monomer leaching of three experimental urethane dimethacrylate (UEDMA)-hydroxypropyl methacrylate (HPMA)-based resin systems were studied. Three experimental resins (E1: 70.6 wt% UEDMA + 27.4 wt% HPMA, E2: 80.6 wt% UEDMA + 17.4 wt% HPMA, E3: 90.6 wt% ...
To evaluate the effect of photo-initiator on the degree of conversion (DC) and elution of Bis-GMA and HEMA for 8 one-step adhesive formulations. We used Scotchbond Universal ('SBU-CQ/amine_4.0', 3M ESPE), containing about 2wt% camphorquinone (CQ) and 2wt% ethyl-4-dimethylamino benzoate...
Objectives: To verify the relationship between contraction stress and degree of conversion (DC) in different composites (Filtek Z250, Filtek A110, Tetric Ceram and Heliomolar). Methods: For the contraction stress test, composite (2 mm thick) was applied between two 5-mm diameter glass rods, mou...
Objective: Two major categories of dentin bonding systems (etch-and-rinse and self-etching) are available, which differs regarding the mode of use and the stability of the adhesive/dentin interface. The aim of this in vitro study was to compare two modes of use recommended by the universal ...
The results obtained were then fitted by a non-linear least square method to a rational function, which permitted the accurate calculation of the limiting degree of conversion. The latter was found to increase in the order Bis-GMA<Bis-EMA<UDMA<TEGDMA. This trend is discussed in connection ...
Aim: The aim of this study is to evaluate the influence of different combinations of irradiance and exposure time for a given radiant exposure on the degree of conversion (DC) and on the mechanical properties of two resin composites: Filtek Z250 and Filtek P90 LS (3M ESPE). Materials and ...
