The invention relates to a method for producing an aerogel material with a porosity of at least 0.55 and an average pore size of 10 nm to 500 nm, having the following steps: a) preparing and optionally activating a sol; b) filling the sol into a casting mold (10); c) gelling the sol, whereby a gel is produced, and subsequently aging the gel; at least one of the following steps d) and e), d) substituting the pore liquid with a solvent; e) chemically modifying the aged and optionally solvent-substituted gel (6) using a reaction agent; followed by f) drying the gel, whereby the aerogel material is formed. The casting mold used in step b) is provided with a plurality of channel-forming elements (2) which are designed such that the sol filled into the casting mold lies overall at a maximum distance X from a channel-forming element over a specified minimum length L defined in the channel direction of the elements, with the proviso that X<15 mm and L/X>3.

This invention relates to a formulation comprising a proteinaceous microgel and one or more biopolymeric nanofibrils. The invention also relates to methods for preparing such formulations. The invention also contemplates the uses of the formulations.

Methods and materials are described for preparing organic-inorganic hybrid gel compositions where a sulfur-containing cross-linking agent covalently links the organic and inorganic components. The gel compositions are further dried to provide porous gel compositions and aerogels. The mechanical and thermal properties of the dried gel compositions are also disclosed.

The present disclosure provides methods for forming sol-gels, sol-gel films and substrates, such as vehicle components, having a sol-gel film disposed thereon. At least one method of forming a sol-gel includes mixing a metal alkoxide, an acid stabilizer, and an organic solvent to form a first mixture having about 10 wt % or less water content based on the total weight of the first mixture. The method includes mixing an organosilane with the first mixture to form a second mixture having about 10 wt % or less water content based on the total weight of the second mixture.

A dispersion containing a dispersed phase comprising drops and a continuous aqueous phase, preferably in the form of gel, in which the drops comprise a fatty phase containing at least one gelling agent, and in which the fatty phase comprises at least one non-volatile hydrocarbon oil H1 containing more than 90%, and preferably more than 95%, fatty acids having at least 18 carbon atoms and preferably at least 20 carbon atoms.

To provide methods for producing a wet gel and a xerogel, in which variation in gel thickness is little even without highly controlling the levelness of the mold and the gels are less likely to break at the time of gelation or demolding. The method for producing a wet gel comprises, in such a state that a second liquid layer 14 made of a second liquid containing a gel raw material, is present on a first liquid layer 12 made of a first liquid, letting the second liquid layer 14 be gelled. The method for producing a xerogel comprises drying the wet gel thereby produced or a solvent-substituted gel obtainable by subjecting said wet gel to solvent substitution.

A new type of biomaterial that can be generated from pollen, methods for its production, the various uses thereof in, for example, biological, medicinal, cosmetic, nutritional and printing applications and the materials/devices that comprise this new material are provided. The biomaterial comprises microgels of sporoderm polymer complex microcapsules (SPC-MCs), produced by deproteinizing the pollen from eudicot plants, in particular of genus Baccharis, Helianthus or Camellia, by contacting it with an aqueous base solution at elevated temperatures for up to 10 hours to obtain porous SPC-MCs, and hydrolytically degrading the SPC-MCs by contacting it with an aqueous base solution for periods up to 60 days to obtain microgels of SPC-MCs.

This invention relates to gels encapsulating organometallic reagents, particularly organolithium reagents. The invention also relates to methods of making said gels and methods of using said gels. The gels are particularly useful in organic synthesis being easier to handle than the organometallic reagent solutions typically used.
