Degree of double bond conversion in light-cured composites

Dental Materials, 1987
The curing pattern of five commercial light-cured composites was investigated. Micro-ATR infrared spectroscopy was used to evaluate the degree of cure as a function of distance from the exposed surface and curing time. KHN measurements were also obtained for each depth to relate the hardness pattern to the degree of conversion.

Macropolyhedral boron-containing cluster chemistry. Ligand-induced two-electron variations of intercluster bonding intimacy. Structures of nineteen-vertex[(eta(5)-C5Me5) HIrB18H19(PMe2Ph)] and the related carbene complex [(eta(5)-C5Me5)HIrB18H19{C(NHMe)(2)}] [PDF]

, 2004
Addition of PMe2Ph to fused-cluster syn-[(η5-C5Me5)IrB18H20] 1 to give [(η5-C5Me5)HIrB18H19(PMe2Ph)] 3 entails a diminution in the degree of intimacy of the intercluster fusion, rather than retention of inter-subcluster binding intimacy and a nido ...

Radicals in carbonaceous residue deposited on mordenite from methanol [PDF]

, 2016
It is shown that control of the degree of coking can lead to the observation of hyperfine structures in the carbonaceous residues deposited from methanol over mordenite (H-MOR) at temperatures relevant to the conversion of methanol to hydrocarbons.

90 degree polarization rotator using a bilayered chiral metamaterial with giant optical activity

, 2010
A bilayered chiral metamaterial (CMM) is proposed to realize a 90 degree polarization rotator, whose giant optical activity is due to the transverse magnetic dipole coupling among the metallic wire pairs of enantiomeric patterns.
