Nanocellulose Xerogels With High Porosities and Large Specific Surface Areas
Frontiers in Chemistry, 2019 Xerogels are defined as porous structures that are obtained by evaporative drying of wet gels. One challenge is producing xerogels with high porosity and large specific surface areas, which are structurally comparable to supercritical-dried aerogels ...

Magnetic Study of CuFe2O4-SiO2 Aerogel and Xerogel Nanocomposites
Nanomaterials, 2021 CuFe2O4 is an example of ferrites whose physico-chemical properties can vary greatly at the nanoscale. Here, sol-gel techniques are used to produce CuFe2O4-SiO2 nanocomposites where copper ferrite nanocrystals are grown within a porous dielectric silica ...

Investigation of silica - PVA xerogel microstructure evolution during thermal treatment by SANS experiment [PDF]
, 2004 The purpose of the study was to investigate the appearance of certain microstructures developing in the SiO2/PVA nanocomposite xerogels at different temperatures by small-angle neutron scattering (SANS). The samples were prepared by the alcoxide route of

The Role of Cations in Resorcinol–Formaldehyde Gel Textural Characteristics
Gels, 2022 The production of resorcinol–formaldehyde xerogels has yielded insight into the gelation processes underpinning their structures. In this work, the role of the cation species from the catalyst is probed by studying the simultaneous addition of sodium ...

Podoplanin immunopositive lymphatic vessels at the implant interface in a rat model of osteoporotic fractures [PDF]
, 2013 Insertion of bone substitution materials accelerates healing of osteoporotic fractures. Biodegradable materials are preferred for application in osteoporotic patients to avoid a second surgery for implant replacement. Degraded implant fragments are often

Porosity in Polysilsesquioxane Xerogels [PDF]
MRS Proceedings, 1999 ABSTRACTPolymerization of organotrialkoxysilanes is a convenient method for introducing organic functionality into hybrid organic-inorganic materials. However, not much is known about the effects of the organic substituent on the porosity of the resulting xerogels.

Exploring the difference in xerogels and organogels through in situ observation [PDF]
Royal Society Open Science, 2018 Solvent–gelator interactions play a key role in mediating organogel formation and ultimately determine the physico-chemical properties of the organogels and xerogels.

Ceramic nanostructure materials, membranes and composite layers [PDF]
, 1989 Synthesis methods to obtain nanoscale materials will be briefly discussed with a focus on sol-gel methods. Three types of nanoscale composites (powders, membranes and ion implanted layers) will be discussed and exemplified with recent original research ...
