    摘要： The present invention relates to the field of protecting value documents and value commercial goods against counterfeit and illegal reproduction. In particular, the present invention provides processes for producing optical effect layers (OELs) comprising non-spherical magnetic or magnetizable particles and comprising a motif made of at least two areas made of a single applied and cured layer, said motif being obtained by using a selective curing performed by irradiation with an actinic radiation LED source (x41) comprising an array of individually addressable actinic radiation emitters.

    摘要： Methods for forming and controlling morphology cracks in silicon dioxide (SiO2) film comprising: preparing SiO2precursor solution comprising solvent, precursor of SiO2, precursor of metal oxide nanocrystals, water, and acid; coating the solution onto substrate; drying the solution atop the substrate at a temperature between about 20° C. to 100° C. between 1 minute to 24 hours to form SiO2 film having uniformly dispersed metal oxide nanocrystals, wherein shorter drying times yield substantially spherical shaped metal oxide nanocrystals and longer drying times yield rod and disc shaped metal oxide nanocrystals; and thermally treating the SiO2 film between about 60° C. to 500° C. between 1 minute to 24 hours to form cracked mesh SiO2 film, wherein two cracks initiate from rod shaped metal oxide nanocrystals, three to four cracks initiate from spherical shaped metal oxide nanocrystals, and four or more cracks initiate from disc shaped metal oxide nanocrystals. Other embodiments are described and claimed.

    摘要： A unique fiber core sampler composition, related systems, and techniques for designing, making, and using the same are described. The sampler is used to interface with existing field instrumentation, such as Ion Mobility Spectrometer (IMS) equipment. Desired sampler characteristics include its: stiffness/flexibility; thermal mass and conductivity; specific heat; trace substance collection/release dependability, sensitivity and repeatability; thickness; reusability; durability; stability for thermal cleaning; and the like. In one form the sampler has a glass fiber core with a thickness less than 0.3 millimeter that is coated with a polymer including one or more of: polymeric organofluorine, polyimide, polyamide, PolyBenzlmidazole (PBI), PolyDiMethylSiloxane (PDMS), sulfonated tetrafluoroethylene (PFSA) and Poly(2,6-diphenyl-p-phenylene Oxide) (PPPO). Multiple polymer coatings with the same or different polymer types may be included, core/substrate surface functionalization utilized, and/or the core/substrate may be at partially filled with thermally conductive particles.

    摘要： This disclosure provides methods and systems that comprise a misting unit for atomizing a water-based or solvent-based composition, such as a liquid composition thereof to create a mist. Further, the disclosed methods and systems may include introducing, through an airtight aperture in a pipe or substrate, the mist into the pipe or the substrate. Further still, the disclosed methods and systems may include propelling, by an inert or non-inert gas, the mist onto at least a portion of the interior surface of a substrate connected to or integrated with the pipe within a closed system. The misting unit may be removably or irremovably connected to the pipe for optionally removably connecting to the substrate.
