The feasibility of applying time-domain, terahertz spectroscopic imaging to the evaluation of underdrawings and paint layers embedded within wall paintings is demonstrated. Metallic and dielectric paint patterns and a graphite drawing are resolved through both paint and plaster overlayers using a pulsed-terahertz reflectometer and imaging system. We calculated the bulk refractive indices of fou...

Cuprous oxide-based antifouling paint is now the most common type in use, especially in the shipping industry. Anti-fouling paints prevent or slow down the growth of organisms attached to the hull, in order to improve a vessel’s performance and durability. However, copper is a scarce resource and never can be retrieved or recycled after leaching into the sea. The need to protect sensitive marin...

OBJECTIVES To evaluate the regional mechanical properties of dual-cure resin composites and their regional bond strengths to root canal dentin. METHODS One of the following dual-cure resin composites was placed in artificial post spaces: Unifil Core (UC), Clearfil DC Core (DC), Build-It FR (BI), Clearfil DC Core-automix (DCA), and photo-cured for 60s. After 24h storage, each specimen was seri...

Vehicle coating is an important component of automotive manufacturing. The paint shop constitutes the plurality of initial investment in an automotive assembly plant, consumes the majority of energy used in the plant's operation, and generates significant waste from paint overspray. The coating process also results in the emission of polluting volatile organic compounds (VOCs). New paint techno...

The U.S. Automotive industry is struggling with the adoption of a solvent-free powder coating technology as a replacement for traditional liquid painting technology which is considered to be environmentally harmful. The Low Emission Paint Consortium (LEPC) was formed by Chrysler, Ford, and General Motors to tackle many of the technical issues that are associated with bringing a new technology i...

The aim of this project was to determine whether any intersample variations between architectural paint products of the same brand could be established. Different batches of the same product were analysed to test whether they could be distinguished. Samples analysed included batches of white paint manufactured over several months and red and blue colour samples. Samples were analysed by microsc...

An oil painting by Claude Monet, Port-Goulphar, Belle-Ile 1887 (collection of the Art Gallery of New South Wales), was examined to determine both the identity of the pigments used by the artist in this painting and his technique of mixing colors and laying paint on the canvas. The extremely complex construction of the painting was revealed by optical microscopy, scanning electron microscopy (SE...

Title X of the Housing and Community Development Act of 1992 addresses the control of lead-based paint hazards in federally assisted housing. It also provides for consistency and quality control in evaluating and controlling lead hazards in all housing. At the time of sale or rental of privately owned housing built before 1978, the year the Consumer Product Safety Commission banned the resident...
