The extensional rheological properties of dilute polymer solutions play a dominant role in many commercial processes such as air-assisted atomization. This is a high deformation rate process important in application of diverse materials such as paints, fertilizer sprays and delivery of airborne drugs. Dilute polymeric solutions which have identical values of high shear-rate viscosity (HSV) ofte...

Robots are being increasingly utilized for various operations in industrial and household applications. One such application is spray painting, wherein atomized paint particles sprayed on a surface to coat the with paint. As there different models of robots available job, it becomes crucial select best among them. Multi-criteria decision-making (MCDM) techniques widely used fields tackle select...

Graffiti on facades often has a heavy impact in social and economic terms, particularly when historical and artistic artefacts are affected. To limit the damages to the surfaces, preventive plans are implemented and anti-graffiti coatings are used as a protective measure. In this study, the distribution of a spray paint inside a highly porous stone, with and without anti-graffiti protection, wa...

For automated spray painting robots, the choice of a start curve from which all subsequent paths will be determined, plays a critical role in ensuring uniform coverage of the target surface. In this paper, we ultimately propose a method to determine the start curve for two different procedures of coverage path construction. For the first procedure, we average the target surface normal to optimi...

Traditional photolithography begins with single-photon absorption of patterned light by a photo-initiator to locally expose a resist. In two-color photo-initiation/inhibition (2PII) lithography, these exposed regions are confined by a surrounding pattern of inhibitors generated by one-photon absorption of a second color in a photo-inhibitor. Like a stencil used to confine spray-paint to a thin,...

Many applications in a diverse demographic of engineering fields require knowledge of the thickness of thin films and coatings. An example of some applications for which thin film thickness is critical are semiconductors, optics, and protective coatings. There are various methods for measuring thin film thickness, however, many of them are destructive, or are only capable of measuring thickness...

The high activity of metallic zinc particles with water, and consequently the short pot lift a mixed waterborne organic zinc-rich paint, are most well-known problem for their application. In this study, powders were modified by silane-crosslinked potassium silicate paint’s life was prolonged. Electron microscopy analysis showed that spheres in paint encapsulated shell consisted resin. modificat...
