We studied the OH oxidation of submicron aerosol particles consisting of pure palmitic acid (PA) or thin (near monolayer) coatings of PA on aqueous and effloresced inorganic salt particles. Experiments were performed as a function of particle size and OH exposure using a continuous-flow photochemical reaction chamber coupled to a chemical 5 ionization mass spectrometer (CIMS) system, for detect...

Silica-based sol-gel antireflective (AR) optical coatings are critical components of high peak power laser systems. Water vapor and volatile organic compounds can contaminate these coatings, reducing both their antireflective efficiency and laser-damage resistance. Previous work has shown that alkylation of free hydroxyl groups on the silica sol-gel with organosilicon compounds in solution can ...

Technical development and commercial implementation of the supercritical fluid spray process have produced the surprising result that coating appearance and performance can actually be improved by removing 60 to 80 percent of the organic solvent from solvent-borne coating formulations. Unlike normal diluent solvents and water, the decompressive release of supercritical carbon dioxide during spr...

The goal of a durable exterior clear coating has eluded generations of coatings technologists, despite long-standing desire amongst the public for such a coating. The journey towards this goal initially focused on modifications to coating formulation, but took a completely different direction when it was found that a UV-transparent silicone clear coating on wood modified with chromic acid met c...

We have produced passivating coatings on 80-nm aluminum particles by plasma-enhanced chemical vapor deposition (PECVD). Three organic precursors--isopropyl alcohol, toluene, and perfluorodecalin--were used to fabricate thin films with thicknesses ranging from 5 nm to 30 nm. The coated samples and one untreated sample were exposed to 85% humidity at 25 °C for two months, and the active Al conten...

Highly and homogeneously crosslinked poly(beta-ketoester) networks densely bearing robust nitroxide radicals were prepared via a click-type and stepwise Michael polyaddition. A half-battery cell composed of the thermally-cured radical network coatings displayed a rapid, reversible, and almost stoichiometric redox-activity even with a thickness of ca. 10 mum, which may be applicable as the elect...

Isocyanate-free cathodic ED coatings. Most of the resins used in the cathodic electrodeposition (CED) coatings are made from modified epoxy resin and blocked polyisocyanate in which the crosslinking is achieved by polyurethane and polyurea formation. A resin system has been developed that is isocyanate free and avoids not only the toxicity aspect, but also, to a great extent, the weight loss of...
