Dielectric characterisation of chitosan-based composite membranes containing fractionated kraft and organosolv lignin
(Elsevier, 2024-03)
Chitosan-based composite membranes with fractionated kraft and organosolv lignin were prepared by solvent casting. A small lignin fraction (1%) was added to the neat chitosan to obtain a good distribution. The influence ...
Self-assembly and crystallization of double crystalline aliphatic thermoplastic biopolyurethane and its nucleation with cellulose nanocrystals
(Elsevier, 2022-01-13)
[EN] An aliphatic segmented thermoplastic biopolyurethane (STPU), based on aliphatic hexamethylene diisocyanate (HDI) and 1,3 propanediol (1,3PD) as urethane rich phase and a poly(sebacate) as a macrodiol phase, with ~50 ...
Sustainable production of cellulose nanofiber from sugarcane trash: A quality and life cycle assessment
(Elsevier, 2021-09-29)
Developing green processes in the chemistry and engineering domains is one of the most significant challenges for sustainable production. Sugarcane trash (ST) generated during the sugar extraction process is an excellent ...
Poliuretanozko-itsasgarrien sintesia ligninan oinarritutako biopoliolak erabiliz

Cada vez hay más patógenos resistentes ante agentes antimicrobianos. Por ello, es indispensable desarrollar nuevas estrategias para hacer frente a este problema. Una estrategia interesante es la de combinar fármacos con ...
Development of Flame-Retardant Polylactic Acid Formulations for Additive Manufacturing
(MDPI, 2024-04-10)
Polymeric materials, renowned for their lightweight attributes and design adaptability, play a pivotal role in augmenting fuel efficiency and cost-effectiveness in railway vehicle development. The tailored formulation of ...
Optimization of Ink Composition and 3D Printing Process to Develop Soy Protein-Based Scaffolds
(MDPI, 2024-03-25)
Inks based on soybean protein isolate (SPI) were developed and their formulations were optimized as a function of the ink heat treatment and the content of other biopolymers to assess the effects of protein–polysaccharides ...
Preparation of Filter Paper from Bamboo and Investigating the Effect of Additives
(MDPI, 2024-04-24)
As air pollution escalates, the need for air filters increases. It is better that the filters used be based on natural fibers, such as non-wood fibers, which cause low damage to the environment. However, the short fiber ...
Thermally-Activated Shape Memory Behavior of Biodegradable Blends Based on Plasticized PLA and Thermoplastic Starch
(MDPI, 2024-04-16)
Biodegradable blends based on plasticized poly(lactic acid) PLA and thermoplastic starch (TPS) have been obtained. The influence of the PLA plasticizer as a compatibility agent has been studied by using two different ...
Tribological Performance of a Paraffinic Base Oil Additive with Coated and Uncoated SiO2 Nanoparticles
(MDPI, 2024-04-25)
Electric vehicles (EVs) have emerged as a technology that can replace internal combustion vehicles and reduce greenhouse gas emissions. Therefore, it is necessary to develop novel low-viscosity lubricants that can serve ...
Graphene-based versus alumina supports on CO2 methanation using lanthanum-promoted nickel catalysts
(Springer Nature, 2024-05)
The valorization of CO2 as a biofuel, transforming it through methanation as part of the power-to-gas (P2G) process, will allow the reduction of the net emissions of this gas to the atmosphere. Catalysts with 13 wt.% of ...
