Enhanced Biodegradability in Soil of Chicken Feather by Steam Explosion for Potential Application in Agricultural Biodegradable Plastics
Vadillo, Julen; Montes, Sarah; Grande, Hans-Jürgen; Verstichel, Steven; Almqvist, Jonna; Wrzesniewska-Tosik, Krystyna (MDPI, 2023-09-08)Feather waste is a major issue from an economic and environmental point of view. Even though there are already routes for the valorisation of feathers into fertilisers and feather meal, these are considered to have low ... -
Flexible Biocomposites with Enhanced Interfacial Compatibility Based on Keratin Fibers and Sulfur-Containing Poly(urea-urethane)s
Aranberri, Ibon; Montes, Sarah; Azcune, Itxaso; Rekondo, Alaitz; Grande, Hans-Jürgen (MDPI, 2018-09-21)Feathers are made of keratin, a fibrous protein with high content of disulfide-crosslinks and hydrogen-bonds. Feathers have been mainly used as reinforcing fiber in the preparation of biocomposites with a wide variety ... -
Fully Biodegradable Biocomposites with High Chicken Feather Content
Aranberri, Ibon; Montes, Sarah; Azcune, Itxaso; Rekondo, Alaitz; Grande, Hans-Jürgen (MDPI, 2017-11-09)The aim of this work was to develop new biodegradable polymeric materials with high loadings of chicken feather (CF). In this study, the effect of CF concentration and the type of biodegradable matrix on the physical, ... -
High performance carbon free bifunctional air electrode for advanced zinc-air batteries
Ramos Mainar, Aroa; Blázquez, José Alberto; Frattini, Domenico; Enterría, Marina; Ortiz-Vitoriano, Nagore; Urdampilleta, Idoia; Grande, Hans-Jürgen (Elsevier Ltd, 2023-04-01)Secondary zinc-air batteries (ZABs) offer a promising alternative for the future of sustainable energy storage. However, the current capability of secondary ZABs is far from satisfactory. The limitations for achieving high ... -
Improved Thermal Insulating Properties of Renewable Polyol Based Polyurethane Foams Reinforced with Chicken Feathers
Aranberri, Ibon; Montes, Sarah; Wesołowska, Ewa; Rekondo, Alaitz; Wrzesniewska-Tosik, Krystyna; Grande, Hans-Jürgen (MDPI, 2019-12-03)In the present work, sustainable rigid polyurethane foams (RPUF) reinforced with chicken feathers (CF) were prepared and characterized. The bio-based polyol used to formulate the foams was obtained from castor oil. This ... -
Influence of the Ambient Storage of LiNi0.8Mn0.1Co0.1O2 Powder and Electrodes on the Electrochemical Performance in Li-ion Technology
De Meatza, Iratxe; Landa Medrano, Imanol; Sananes Israel, Susan; Eguía Barrio, Aitor; Bondarchuk, Oleksandr; Lijó Pando, Silvia; Boyano, Iker; Palomares Durán, Verónica ; Rojo Aparicio, Teófilo ; Grande, Hans-Jürgen; Urdampilleta, Idoia (MDPI, 2022-07-28)Nickel-rich LiNi0.8Mn0.1Co0.1O2 (NMC811) is one of the most promising Li-ion battery cathode materials and has attracted the interest of the automotive industry. Nevertheless, storage conditions can affect its properties ... -
Systematic cycle life assessment of a secondary zinc–air battery as a function of the alkaline electrolyte composition
Mainar, Aroa R.; Iruin, Elena; Colmenares, Luis C.; Blázquez Martín, José Alberto; Grande, Hans-Jürgen (Society of Chemical Industry and John Wiley & Sons Ltd., 2018-05-30)Development of secondary zinc-air batteries goes through a proper specification of the electrolyte formulation adapted to extend the cycle life of the battery. However, defining an optimal formulation is not a trivial work ... -
The effect of the evaporation rate on electrochemical measurements with paper-based analytical devices and its minimisation by enclosure with adhesive tape
Lamas-Ardisana, Pedro J.; Martínez-Paredes, Graciela; Añorga, Larraitz; Grande, Hans-Jürgen (Elsevier, 2019-02-15)In this work, the effect of liquid evaporation on electrochemical measurements with electrochemical paper-based devices (ePADs) is studied. The time evolution of cyclic voltammograms of ferricyanide is used to study the ...
