Structure and thermal stability in hydrophobic Pluronic F127-modified silica aerogels
(2018-09-01)
Hydrophobic ambient pressure drying (APD) aerogels were prepared from hydrolysis of tetraethylorthosilicate (TEOS) in solutions with different concentrations of poly(ethylene oxide)–poly(propylene oxide)–poly(ethylene ...
Structure and diffuse-boundary in hydrophobic and sodium dodecyl sulfate-modified silica aerogels
(2016-03-15)
Small-angle X-ray scattering (SAXS) and nitrogen adsorption were used to study ambient pressure drying (APD) silica aerogels prepared from hydrolysis of tetraethoxysilane (TEOS) with additions of sodium dodecyl sulfate ...
Antibacterial activity against Staphylococcus aureus of chitosan/chondroitin sulfate nanocomplex aerogels alone and enriched with erythromycin and elephant garlic (Allium ampeloprasum L. var. ampeloprasum) extract
(2018)
The antibacterial activity against Staphylococcus aureus of aerogels fabricated from colloidal suspensions of chitosan/chondroitin sulfate nanocomplexes is analyzed. Upon freeze-drying the colloidal suspensions, the aerogels ...
Caracterización de aerogeles basados en óxido de grafeno y gelatina con carga de extractos de uva país como potencial agente hemostático.
(Universidad de Concepción.Departamento de Ingeniería QuímicaDepartamento de Ingeniería Química., 2020)
La hemorragia es una de las principales causas de muerte por traumas, incluso en
su tratamiento, debido al sangramiento continuo y coagulopatías. Por lo cual, el
desarrollo de nuevos materiales hemostáticos, es de vital ...
Production of silica aerogel microparticles loaded with ammonia borane by batch and semicontinuous supercritical drying techniques
(Elsevier Science, 2014-06)
Silica aerogel microparticles were prepared by supercritical drying and used as support for hydrogen-storing ammonia borane (AB). The formation of aerogel microparticles was done using two different processes: batch ...

Aerogel nanocompósito nanocelulose/hidroxiapatita com propriedades retardante de chama
(Joinville, SC, 2021-08-16)
Atualmente, aerogéis celulósicos, ultraleves e de recursos renováveis são um dos materiais de grande interesse devido à sua matéria-prima altamente abundante e barata, baixa condutividade térmica, entre outras propriedades. ...
A facile and green synthesis of a MoO2-Reduced graphene oxide aerogel for energy storage devices
(2020-02-01)
A simple, low cost, and green method of hydrothermal synthesis, based on the addition of l-ascorbic acid (L-AA) as a reducing agent, is presented in order to obtain reduced graphene oxide (rGO) and hybrid rGO-MoO2 aerogels ...
Graphenic Aerogels Decorated with Ag Nanoparticles as 3D SERS Substrates for Biosensing
(2020-07-01)
A versatile and efficient surface-enhanced Raman scattering (SERS) substrate based on a hybrid aerogel composed of reduced graphene oxide (rGO) decorated with silver nanoparticles (AgNPs), suitable for highly sensitive ...
