The invention relates to a hydrogel product comprising glycosaminoglycan molecules as the swellable polymer, wherein the glycosaminoglycan molecules are covalently crosslinked via crosslinks comprising a spacer group selected from the group consisting of di-, tri-, tetra-, and oligosaccharides.

A microwave absorbing materials or gel is disclosed. In some examples, the material can be used in communication, radar, or industrial applications or to reduce the cross section of aircrafts or ships. The gel can be used as an absorbing material is to dampen microwaves. For example, to reduce coupling between antennas, shielding of measurement system to remove disturbances from internal or external error sources, provide a matching between the antenna and the body. The absorbing material can be manufactured as a flexible and moldable gel from polymers, water, and mineral salt. By altering the ratios of the content different damping and mechanical properties of the gel can be obtained. The surface of the material is modified to densify the surface and to reduce the surface slipperiness, avoid evaporation from the gel and to enable disinfection of the surface.

The invention relates to an aqueous binder composition comprising a carbohydrate component, possibly a crosslinker and possibly reaction product of carbohydrate component with crosslinker, further comprising a phenalkamine. The invention further discloses binders obtained therefrom and composite products manufactured therewith.

The present disclosure is directed to compositions including a microemulsion comprising lecithin, a polysorbate, an alkyl polyglycoside, and optionally a solvent. Uses of the microemulsions are also disclosed.

Disclosed is a method for preparing a bilayer scaffold through single process comprising: preparing a first polymer aqueous solution; adding a second polymer into the first polymer aqueous solution and stirring a reactant; adding a surfactant into the stirred reactant and stirring the reactant at high temperature and high speed; freeze-drying the stirred reactant thereby obtaining a sponge; dipping the sponge in a cross-linking agent thereby rendering be cross-linked; and freeze-drying the cross-linked reactant.

The present disclosure is directed to highly concentrated foam formulations for blast suppression and dispersion mitigation. for use in responding to a terrorism incident involving a blast dispersion device. The foam formulation is more concentrated and more stable than current blast suppression foams, which reduces the logistics burden on the user.

In an embodiment, the carrageenan may be -carrageenan. In an embodiment, the bio waste solution may include fish scales.

The disclosure generally relates to poly alpha-1,3-glucan compositions and articles containing them. In particular interest is comprising poly alpha-1,3-glucan ester derivatives. The poly alpha-1,3-glucan derivatives are useful in thermoprocesses and in particular, injection molding processes.

The invention relates to a process for producing a pulverulent composition comprising at least one polymeric dispersant (PD) which comprises structural units having anionic and/or anionogenic groups and structural units having polyether side chains, and at least one polysaccharide (PS). The process here comprises the process steps: a) production of an aqueous dispersion having a viscosity of the dispersion of less than 10 000 mPa.Math.s, comprising the at least one polymeric dispersant (PD) and the at least one polysaccharide (PS) and b) spray drying of the aqueous dispersion produced in process step a). Furthermore, the use of the pulverulent composition according to the invention in inorganic binder compositions, especially as a rheological additive, is disclosed.

A system for making and using a ground product that includes one or more of: a reactor operated to react a guar split with a reagent at a reaction temperature in a range of 120 F. to 180 F. to form a guar derivative, and a treatment and transfer section for optionally treating the guar derivative and transferring the guar derivative to a co-grinder. The co-grinder is operably associated with a heated vacuum system and is operated to co-grind an acid with the guar derivative to form a ground product.
