Aerogel-based metasurfaces for perfect acoustic energy absorption

Fernandez-Marin, Antonio A.; Jimenez, Noe; Groby, Jean-Philippe; Sánchez-Dehesa Moreno-Cid, José; Romero García, Vicente (American Institute of Physics, 2019-08-05)

[EN] The unusual viscoelastic properties of silica aerogel plates are efficiently used to design subwavelength perfect sound absorbers. We theoretically, numerically and experimentally report a perfect absorbing metamaterial ...
Aerogeles biodegradables aplicados a la agroindustria

Sillero Vizcaíno, Claudia (Universitat Politècnica de València, 2023-09-14)

[ES] El aumento de los periodos de sequía supone uno de los principales problemas para el sector agrícola, tanto a nivel nacional como global. A causa del ascenso global de la temperatura media y el descenso de las ...
Effect of synthesis conditions on CO2 capture of ethylenediamine-modified graphene aerogels

Pruna, Alina Iuliana; Cárcel, Alfonso Cristóbal; Benedito-Borrás, Adolfo; Giménez Torres, Enrique (Elsevier, 2019)

[EN] Ethylenediamine-modified graphene oxide-based three-dimensional aerogels were fabricated by one-step hydrothermal technique. The influence of oxidation conditions and starting graphite material was studied by elemental ...
Enhanced CO2 Capture of Poly(amidoamine)-Modified Graphene Oxide Aerogels with the Addition of Carbon Nanotubes

Pruna, Alina Iuliana; Cárcel, Alfonso Cristóbal; Benedito, Adolfo; Giménez Torres, Enrique (MDPI AG, 2023-02)

[EN] Innovative dendrimer-modified graphene oxide (GO) aerogels are reported by employing generation 3.0 poly(amidoamine) (PAMAM) dendrimer and a combined synthesis approach based on the hydrothermal method and freeze-casting ...
Hydrothermal-Freeze-Casting of Poly(amidoamine)-Modified Graphene Aerogels towards CO2 Adsorption

Pruna, Alina Iuliana; Cárcel, Alfonso Cristóbal; Benedito, Adolfo; Giménez Torres, Enrique (MDPI AG, 2021-09)

[EN] This article presents novel poly(amidoamine) (PAMAM) dendrimer-modified with partially-reduced graphene oxide (rGO) aerogels, obtained using the combined solvothermal synthesis-freeze-casting approach. The properties ...
Proceso Certificación EASA para la Aprobación de un Certificado de Tipo mediante un Proceso DOA de un Nuevo Material Aeronáutico, Aerogel
