The process enables control over particle size and surface chemistry, facilitating their use in agriculture, healthcare, and advanced materials. The valorization of lignin\u2014a major by-product of the pulp and paper industry\u2014supports circular-economy principles and provides a sustainable alternative to petroleum-derived materials.<\/span><\/p>\n<p><b>Status: <\/b><span style=\"font-weight: 400;\">Filled<\/span><\/p>\n<p><b>Contact: <span style=\"font-weight: 400;\">Prof. <\/span><a href=\"http:\/\/lattes.cnpq.br\/4741480538883395\"><span style=\"font-weight: 400;\">Leonardo Fernandes Fraceto<\/span><\/a><span style=\"font-weight: 400;\"> (UNESP Sorocaba)<\/span><\/b><\/p>","protected":false},"excerpt":{"rendered":"<p>T\u00edtulo:PROCESSO VERDE PARA OBTEN\u00c7\u00c3O DE FRA\u00c7\u00d5ES ESPEC\u00cdFICAS DE LIGNINA KRAFT E APLICA\u00c7\u00d5ES EM NANOTECNOLOGIA Tipo de prote\u00e7\u00e3o: Privil\u00e9gio de Inova\u00e7\u00e3o N\u00famero do registro: BR1020240201817 Institui\u00e7\u00e3o de registro: INPI \u2013 Instituto Nacional da Propriedade Industrial Data de dep\u00f3sito: 29\/09\/2024\u00a0 Titular(es): Universidade Estadual Paulista (UNESP) e Universidade Federal de S\u00e3o Carlos (UFSCar) Inventores: Dra.
