Measurement of segmental mobility during constant strain rate deformation of a poly(methyl methacrylate) glass [PDF]

, 2013
We describe an apparatus for performing constant strain rate deformations of polymer glasses while simultaneously measuring the segmental mobility with an optical probe reorientation method. Poly(methyl methacrylate) glasses were deformed at Tg - 19 K, for local strain rates between 3.7x10-5/s and 1.2x10-4/s.

A hydroxamic acid-methacrylated collagen conjugate for the modulation of inflammation-related MMP upregulation [PDF]

Journal of Materials Chemistry B 2018, 2018
Medical devices with matrix metalloproteinase (MMP) modulating functionality are highly desirable to restore tissue homeostasis in critical inflammation states, such as chronic wounds, rotator cuff tears and cancer. The introduction of MMP-modulating functionality in such devices is typically achieved via loading of either rapidly-diffusing chelating ...

Dental sealants and restorations and urinary bisphenol A concentrations in children in the 2003-2004 National Health and Nutrition Examination Survey.

The Journal of the American Dental Association (1939), 2014
BACKGROUND Resin-based dental sealants and composites contain bisphenol A-glycidyl methacrylate, a bisphenol A (BPA) derivative. The authors hypothesized that a greater number of sealants or restorations would be associated with higher urinary BPA ...

Biocompatibility and cytotoxicity of two novel low-shrinkage dental resin matrices

Journal of the Formosan Medical Association, 2014
To reduce the polymerization shrinkage of dental composite resin, we used two different ratios of toluene 2,4-diisocyanate (TDI) or 1,6-hexamethylene diisocyanate (HDI) as functional side chains of bisphenol A-glycidyl methacrylate (bis-GMA) to ...
