The invention concerns a method for producing an optical article suitable for edging comprising an antifouling layer on which there is deposited a temporary overlayer for assisting with edging, comprising: depositing, on an optical substrate, an organic antifouling layer comprising at least a fluorinated polymer compound comprising hydrolysable functions; and depositing, on the antifouling layer, an overlayer for assisting with edging, of mineral nature, comprising one or more metal fluorides and/or one or more metal oxides or hydroxides;

method characterised in that it further comprises a step of accelerated grafting of the antifouling layer chosen from:

(a) a treatment of the deposited antifouling layer in a humid atmosphere of the deposited antifouling layer and

(b) a catalytic treatment in the acidic or basic vapour phase of the deposited antifouling layer.

A sealed article and methods of making the same. The sealed article includes a first and second glass pane. The first and second glass panes include inner surfaces opposite outer surfaces and at least one outer edge. The second glass pane is spaced apart from and positioned substantially parallel to the first glass pane with a low emissivity layer there between. An seal is formed between the first and second glass panes contiguous the low emissivity layer.

A method for forming a self-cleaning coating, comprises providing a first dispersion comprising plasmonic nanoparticles by suspending plasmonic nanoparticles in an organic medium and providing a second dispersion comprising a precursor of a photocatalytic matrix in an organic medium. The method further comprises forming a mixture of the first and second dispersion and coating the mixture on a surface. The method also comprises calcining the coated mixture.

A system for detection of low concentration of explosives via Raman spectroscopy is disclosed that is more specifically a Raman detection substrate having a surface-enhancement effect by using roughened glass (or frosted glass) with a gold/silver nanosponge alloy sputter-deposited onto it under increased pressure resulting in a nano-porous structure to hold the analyte.
