Item type:Publication, Advances in the Sustainable Development of Biobased Materials Using Plant and Animal Waste as Raw Materials: A Review(2024); ; There is substantial concern about critical environmental problems related to waste in production sectors such as textile, construction, and packaging. The materials ascribed to the sectorās unsustainability are primarily fabrics, plastic, and hazardous solvents, making developing new biobased materials imperative. As such, various strategies have been investigated to convert and recycle waste and give them commercial value via the manufacture of biobased materials. This review discusses the various types of raw materials as sources to develop new biobased materials that could promote the transition toward sustainability. According to the literature, the functional qualities of biobased materials are comparable to those of synthetic materials. Raw material sources such as biomass, derived from plant and animal-based waste, are attractive due to their low cost, abundance, and biodegradability. The manufacture of biomaterials, as well as their characterization and performance, are also discussed. Further, this review will offer a comprehensive view of the potential applicability and current commercial applications of the developed biobased materials in relevant areas such as packaging, construction, textile, and wastewater remediation. This could be a potential field of research to address the environmental challenges posed by the continuous growth of the global population.ScopusĀ© Citations 23 2 - Some of the metrics are blocked by yourconsent settings

Item type:Publication, Copper-Modified Cellulose Paper: A Comparative Study of How Antimicrobial Activity Is Affected by Particle Size and Testing Standards(MDPI AG, 2025-01-08); Viviana BenavidesThis study aims to provide evidence that when testing cellulose paper modified with copper particles (CuPs), the particle size and the analysis method influence the antimicrobial activity observed by this material. Commercial CuPs of nanometric size (2.7 nm, CuNPs) and micrometric size (2.5 Āµm, CuMPs) were used to modify cellulose paper sheets. CuPs were incorporated during the pulp disintegration phase (stage 1) of the sheet formation process, according to the ISO 5269-1:2005 standard. Modified paper sheets retained 16% and 14% of CuNPs and CuMPs, respectively. Additionally, CuPs were distributed randomly on the fiber surfaces, often forming aggregates. Finally, the antimicrobial activity of the modified paper sheets was evaluated using ISO 20645:2004 and ISO 20743:2013. The results showed that the antimicrobial activity assessed using each standard method is conditioned by the mechanism of action of the CuPs and, therefore, by their size. It was concluded that ISO 20645:2004 is suitable for evaluating the antibacterial effect of paper/CuNPs, as nanoparticles diffuse from the paper and are released into the culture medium. In contrast, ISO 20743:2013 can be used for both CuNP- and CuMP-based paper, as it evaluates the antibacterial effect based on the direct interaction between the copper particle and the bacteria.ScopusĀ© Citations 2 14 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Proyecto TID: Transferencia - InnovaciĆ³n - DiseƱo para la DiversificaciĆ³n Productiva Exportadora de la RegiĆ³n del BiobĆo, Chile(2020); HernĆ”n DĆaz GĆ”lvez<jats:p>BiobĆo es una de las regiones mĆ”s importantes de Chile a nivel productivo. Fuente de recursos forestales, agropecuarios y pesqueros, polo de desarrollo industrial, de formaciĆ³n de capital humano e investigaciĆ³n, es una de las zonas con mayor proyecciĆ³n de crecimiento y descentralizaciĆ³n. En este contexto, el ComitĆ© de Desarrollo Productivo Regional tiene como objetivo incrementar la capacidad innovadora y la competitividad del tejido empresarial, en especial de sus pequeƱas y medianas empresas. Es aquĆ donde el diseƱo posee un espacio que no se ha formalizado como tal. La Facultad de DiseƱo de la Universidad del Desarrollo ha tenido como misiĆ³n, desde sus comienzos, impulsar la realizaciĆ³n de proyectos acadĆ©micos que posibiliten a sus estudiantes estar en contacto directo con el emprendimiento y los procesos de desarrollo econĆ³mico. Gracias a la adjudicaciĆ³n del Fondo de InnovaciĆ³n para la Competitividad Gobierno Regional del BiobĆo, al apoyo del Instituto de InnovaciĆ³n Interdisciplinaria iCubo UDD y ProChile Regional, a partir de 2014, nace el proyecto TID, el cual permitiĆ³ fortalecer dicho vĆnculo y profundizar el trabajo colaborativo entre la universidad y el sector productivo. TID se planteĆ³ en su inicio como una experiencia piloto para fomentar la transferencia tecnolĆ³gica entre academia y empresa local, a travĆ©s de la disciplina del diseƱo. Su propĆ³sito fue contribuir a la visibilizaciĆ³n de oportunidades para instalar el diseƱo como pieza clave en el engranaje de generaciĆ³n de innovaciĆ³n a nivel regional, aportando al cambio de malla curricular; a la formaciĆ³n de capital humano de diseƱadores entrenados en innovaciĆ³n; a la implementaciĆ³n de infraestructura y tecnologĆas; a la ejecuciĆ³n de un programa piloto de transferencia de diseƱo a 12 empresas regionales; y a la implementaciĆ³n de diversas acciones de difusiĆ³n del diseƱo a nivel regional y nacional como un catalizador de competitividad tanto en economĆas desarrolladas como emergentes. La participaciĆ³n de representantes regionales de instituciones acadĆ©micas, gobierno, asociaciones gremiales y empresarios, y la transferencia de diseƱo a empresas, nos entregaron la oportunidad de contrastar visiones para un mejor entendimiento de la realidad de esta disciplina. Pero no solo eso, tambiĆ©n nos dieron la posibilidad de obtener valiosos aprendizajes, que son la base para la propuesta de desafĆos y responsabilidades a coordinar entre la triada Estado-Academia -Empresa (tambiĆ©n denominada triple hĆ©lice), para incorporar al diseƱo en la Estrategia Regional de InnovaciĆ³n.</jats:p>4
