Capillary Zone Electrophoresis Analysis of Isocyanates in Spray-Painting Operations
… monomers and polyisocyanate oligomers exist in spray painting formulations and are known to be harmful to workers who are exposed to a spray-painting environment. Several methods were used for the sampling and analysis of airborne 1,6- hexamethylene diisocyanate (HDI) monomer and polyisocyanate …

New Sampling and Analysis Method for Isocyanates in Spray-Painting Operations
… HDI. Exposure to isocyanate vapor and aerosol in spray paintings is known to cause a range of disorders in humans. The National Institute for Occupational Safety and Health (NIOSH) has already set the Recommended Exposure Limit for several diisocyanate monomers. The measurement of isocyanates in …

Enabling methodologies for optimal coverage by multiple autonomous industrial robots
… coverage for tasks such as grit-blasting and spray painting several problems need to be addressed. One problem is to partition and allocate the surface areas that multiple AIRs can reach. Another problem is to find a set of appropriate base placements for each AIR and to determine the visiting …

Manufacturing all-polymer laminar flow-based fuel cells
… electrodes are traditionally fabricated by hand-painting or spray painting a catalyst ink onto a gas diffusion electrode or membrane, however electrodes prepared via these techniques do not always have a uniform distribution of catalyst. Recently, e-jet printing has been developed as a method to …

Nonlinear dynamics of complex fluids in fragmentation and fracture
… application of pharmaceutical and agricultural sprays, as well as involuntary physiological processes such as sneezing, are common examples in which the atomized/fractured material contains synthetic or biological macromolecules that result in viscoelastic fluid characteristics. For many of …
