Effects of Aqueous Organic Coatings on the Interfacial Transport of Atmospheric Species
… order to transport between either phase, however organic coated water surfaces are ubiquitous in the environment, and the physical and chemical processes that occur at organic coated aqueous surfaces are often different than those at pure air—water interfaces. Three studies were performed …

Service life of organic coatings: strategies for improving aesthetic and protective durability
It is probably needless to mention that organic coatings are of paramount importance nowadays. Although the huge number of applications and their wide spread can suggest that organic coatings have now reached a level of maturity, they are still mysterious from a certain point of view. The behaviour …

Investigation into corrosion protection by coatings using the electrochemical noise method
… investigate the corrosion protection afforded by organic coatings. A parameter called Noise Resistance (Rn) is derived from an Ohm law relationship using the potential noise (Vn) and current noise (In) values. The noise on the current and potential data sets is calculated as the standard deviation …

Investigation of the Magnetic Properties of Non-Thiolated Au Nano-Structures Grown by Laser Ablation
… are usually coated by thiol-containing organic caps, which are believed to be responsible for the magnetism. However, others suggest that organic capping is not necessary to observe magnetism in Au NPs, and magnetism may be an intrinsic property for nano-structured gold. For this …

In-situ early detection of metal corrosion via "turn-on" fluorescence in "smart" epoxy coatings
<p>Organic coatings (e.g., epoxy coatings) have been widely used to protect metal and metal alloys against corrosion. However protective coating fails with time, leading to corrosion of the metal substrate. When localized corrosion occurs, without being detected, it can result in disastrous failure …
