Microwave-assisted extraction of cellulose nanocrystals from almond (Prunus amygdalus) shell waste
(Frontiers Media, 2023-01)
Almond (Prunus amygdalus) is one of the most common tree nuts on a worldwide basis. This nut is highly regarded in the food and cosmetic industries. However, for all these applications, almonds are used without their shell ...
Enzymatic upgrading of nanochitin using an ancient lytic polysaccharide monooxygenase
(Springer Nature, 2022-08-15)
Numerous enzymes have the potential to upgrade biomass, converting it into high-tech materials for new applications. However, the features of natural enzymes often limit their use beyond chemical conversion of the substrate. ...
Influence of Process Parameters in Graphene Oxide Obtention on the Properties of Mechanically Strong Alginate Nanocomposites
(MDPI, 2020-02-28)
Sodium alginate, a biopolymer extracted from brown algae, has shown great potential for many applications, mainly due to its remarkable biocompatibility and biodegradability. To broaden its fields of applications and improve ...
Towards Circular Economy: Different Strategies for Polyurethane Waste Recycling and the Obtaining of New Products
(MDPI, 2018-11-22)
As a consequence of the high production and simultaneous consumption of polyurethanes
(PU) a great volume of PU waste is landfilled. In this scenario, suitable and efficient routes for PU
waste recycling have been searched ...
Lignocellulosic Biomass as a Source of Raw Materials for the Synthesis of Polyurethanes
(MDPI, 2018-11-06)
Precursors have been satisfactorily synthesized from lignocellulosic biomass for later use in the synthesis of polyurethanes resulting in competitive final properties with those of petroleum derived polyurethanes
Superabsorbent bacterial cellulose spheres biosynthesized from winery by-products as natural carriers for fertilizers
(Elsevier, 2021-11-30)
[EN]Soil contamination, sustainable management of water resources and controlled release of agrochemicals are the main challenges of modern agriculture. In this work, the synthesis of sphere-like bacterial cellulose (BC) ...
Genome sequence and characterization of the bcs clusters for the production of nanocellulose from the low pH resistant strain Komagataeibacter medellinensis ID13488
(Wiley, 2019-02-22)
Komagataeibacter medellinensis ID13488 (formerly Gluconacetobacter medellinensis ID13488) is able to produce crystalline bacterial cellulose (BC) under high acidic growth conditions. These abilities make this strain desirable ...
Water Uptake Behavior and Young Modulus Prediction of Composites Based on Treated Sisal Fibers and Poly(Lactic Acid)
(MDPI, 2016-05)
The main aim of this work was to study the effect of sisal fiber surface treatments on water uptake behavior of composites based on untreated and treated fibers. For this purpose, sisal fibers were treated with different ...
An Alternative Approach for the Incorporation of Cellulose Nanocrystals in Flexible Polyurethane Foams Based On Renewably Sourced Polyols
(Elsevier, 2016-11-16)
Este trabajo analiza tanto el efecto de los nanocristales de celulosa en las propiedades finales de espumas flexibles de poliuretano basadas en castor oil y maíz, sino que además se realiza un análisis en profundidad sobre ...
Strain sensitive conductive polyurethane foam/graphene nanocomposites prepared by impregnation method
(Elsevier, 2017-03-14)
Se prepararon nanocompuestos de espuma de poliuretano conductores mediante la incorporación de flakes de grafeno. Los flakes de grafeno se obtuvieron a partir de grafito por el método de exfoliación líquida en N metilpirrolidona ...
