Azimuthal distinguishability of entangled photons generated in spontaneous parametric down-conversion [PDF]

open access: yes, 2007
We experimentally demonstrate that paired photons generated in different sections of a down-conversion cone, when some of the interacting waves show Poynting vector walk-off, carry different spatial correlations, and therefore a different degree of ...

Uncompleted polymerization and cytotoxicity of dental restorative materials as potential health risk factors

open access: yesAnnals of Agricultural and Environmental Medicine, 2017
Introduction Composite materials used in dentistry indicate adverse biological effects in laboratory conditions. One reason for this activity is incomplete conversion of their polymer matrix, favoring chemical instability and release of biologically ...

Cytotoxicity and Degree of Conversion of Orthodontic Adhesives

open access: yesThe Angle Orthodontist, 2009
Abstract Objectives: To test the hypothesis that there is no difference in the cytotoxicity related to the modes of polymerization of five commercially available orthodontic bonding resins, with and without an oxygen-inhibited layer (OIL), and to evaluate the degree of conversion (DC) of these resins and correlate this to ...
