As part of the Survey of Painters and Repairers of Auto bodies by Yale (SPRAY), the determinants of isocyanate exposure in auto body repair shops were evaluated. Measurements (n = 380) of hexamethylene diisocyanate-based monomer and polyisocyanate and isophorone diisocyanate-based polyisocyanate were collected from 33 auto body shops. The median total reactive isocyanate concentrations expresse...

Polymer-ceramic pressure-sensitive paint (PC-PSP) has been investigated as a surface-pressure sensor for unsteady aerodynamics and short duration measurements. This PSP provides a fast response to a change in pressures with a spray-coating ability. Because it is sprayed onto an aerodynamic surface, the thickness of PC-PSP may play an important role in determining the performance of this sensor....

Associations between isocyanate exposure and respiratory health effects have received little attention despite the extensive use of isocyanate compounds. Spray painters comprise a large population at risk, with potentially high isocyanate exposure because most lacquers contain hexamethylene diisocyanate. Repeated pulmonary function testing is not sufficient to diagnose and evaluate pulmonary to...

Layering a regenerative polymer scaffold on the surface of the heart, termed as a cardiac patch, has been proven to be effective in preserving cardiac function after myocardial infarction (MI). However, the placement of such a patch on the heart usually needs open-chest surgery, which is traumatic, therefore prevents the translation of this strategy into the clinic. We sought to device a way to...

At present, the common protection technology of power-transmission and transformation equipment is mainly coating hot-dip zinc protection. However, due to low adhesion epoxy zinc-rich coating, poor compatibility with top paint, environmental pollution, complex processing, high energy consumption other defects process, its development limited. In view above deficiencies, new anti-corrosion mater...

Digital fabrication, and especially 3D printing, is an emerging field that is opening up new possibilities for craft, art and design. The process, however, has important limitations; in particular, digitally designed artifacts are intrinsically reproducible. In stark contrast, traditional craft artifacts are individually produced by hand. The authors combine digital fabrication and craft in the...

In this paper, we report a study about the application of packaged fiber Bragg gratings used as strain sensors to monitor the stress kinetics during the drying process of commercial latex paints. Three stages of drying with distinct mechanical deformation and temporal behaviors were identified for the samples, with mechanical deformation from 15 μm to 21 μm in the longitudinal film dimension on...

The paint shop plant, as the largest energy consumer in automotive manufacturing process, requires special attention to optimize efficiency and thermal management, reduce environmental impact diminish total costs improve marketability. current review covers description of shop, recognition film layers, characterization spray applicators, evolution their technology's advancement, explanation coa...

We study laser irradiation behavior of multiwalled carbon nanotubes (MWCNT) and chemically modified graphene (rGO)-composite spray coatings for use as a thermal absorber material for high-power laser calorimeters. Spray coatings on aluminum test coupon were exposed to increasing laser irradiance for extended exposure times to quantify their damage threshold and optical absorbance. The coatings,...
