Scalable processing of nanocomposites using photon-based methods

Using a modified CVD infusion process and femtosecond laser irradiation, the methods of the present invention demonstrate the ability to create core-shell nanoparticles of metal and metal oxide nanoparticles embedded within the bulk of an optically transparent substrate. Changes in the optical properties and changes in the structure, size, and shape of the nanoparticles were observed as a result of the methods.

The article may also include a reflective ribbon provided on an upper surface of the base layer, wherein the reflective ribbon positioned along a common plane extending in the second dimension varies as a function of distance across the common plane. has a dihedral angle.

Devices and methods for producing layers with optical effect, containing oriented non-spherical magnetic or magnetisable particles of pigment

FIELD: physics. SUBSTANCE: invention relates to magnetic assemblies and a method of producing layers with an optical effect (LOE) containing magnetically oriented non-spherical magnetic or magnetisable pigment particles on a substrate. In particular, the present invention relates to magnetic assemblies and methods of producing said LOE as counterfeit means on protected documents or articles to be protected or for decorative purposes. EFFECT: disclosed are devices and methods of producing layers with optical effect, containing oriented non-spherical magnetic or magnetized pigment particles. 15 cl, 11 ex, 47 dwg РОССИЙСКАЯ ФЕДЕРАЦИЯ (19) RU (11) (13) 2 715 166 C2 (51) МПК B05B 3/00 (2006.01) B05D 5/06 (2006.01) B05D 3/06 (2006.01) B42D 25/00 (2014.01) B32B 5/16 (2006.01) ФЕДЕРАЛЬНАЯ СЛУЖБА ПО ИНТЕЛЛЕКТУАЛЬНОЙ СОБСТВЕННОСТИ (12) ОПИСАНИЕ ИЗОБРЕТЕНИЯ К ПАТЕНТУ (52) СПК B05B 3/00 (2020.01); B05D 5/06 (2020.01); B05D 3/06 (2020.01); B42D 25/00 (2020.01); B32B 5/16 (2020.01) (21)(22) Заявка: 2018113804, 07.09.2016 (24) Дата начала отсчета срока действия патента: Дата регистрации: (73) Патентообладатель(и): СИКПА ХОЛДИНГ СА (CH) 25.02.2020 10.11.2015 EP 15193837.0 (43) Дата публикации заявки: 13.12.2019 Бюл. № 35 (56) Список документов, цитированных в отчете о поиске: US 20100040845 A1, 12.02.2010.
