The present disclosure provides an aerogel-containing composition including an aerogel, a water-soluble binder, a foaming agent, and a mixture of water and a polar organic solvent as a solvent, and an insulation blanket prepared using the same. In the aerogel-containing composition, the aerogel is uniformly dispersed in the composition, and when preparing a blanket, an insulation blanket having low thermal conductivity and flexibility of low density is prepared without concern of shrinkage of the substrate for a blanket and detachment of the aerogel during a drying process.

An infrared stealth cloth includes a cloth substrate and an infrared light absorber located on the cloth substrate. The infrared light absorber includes a first drawn carbon nanotube film, a second drawn carbon nanotube film, and a third drawn carbon nanotube film stacked on each other. The first drawn carbon nanotube film includes a plurality of first carbon nanotubes substantially extending along a first direction. The second drawn carbon nanotube film includes a plurality of second carbon nanotubes substantially extending along a second direction. The third drawn carbon nanotube film includes a plurality of third carbon nanotubes substantially extending along a third direction. The first direction and the second direction form an angle of about 42 degrees to about 48 degrees, and the first direction and the third direction form an angle of about 84 degrees to about 96 degrees.

Aqueous formulations containing antimicrobial materials dispersed in solutions or emulsions, methods of their preparation, application of such compositions to surfaces, and their resulting coatings. Coating of hydrophobic surfaces with aqueous solutions or suspensions containing antimicrobial materials are disclosed. Several applications of the antimicrobial coatings are described including the coating of solid and porous substrates such as fabrics which may be used for gowns, masks, and other personal protection equipment.

A coated filament for use in additive manufacturing includes a base polymer layer formed of a base polymer material and a coating polymer layer formed of a coating polymer material. At least the coating polymer material is susceptible to dielectric heating in response to electromagnetic radiation, thereby promoting fusion between adjacent beads of coated filament that are deposited during the additive manufacturing process. Specifically, when electromagnetic radiation is applied to an interface area between two adjacent beads of the coated filament, the polymer coating layer melts to diffuse across the interface area, thereby preventing formation of voids. The base polymer material and the coating polymer material of the coated filament also may have similar melting points and compatible solubility parameters to further promote fusion between beads.

A permeable reactive barrier having two or more layers of a geotextile fabric inoculated with a bioremediation microbe is provided. The permeable reactive barrier further includes two or more layers of coarse-grained geological material separating the two or more layers of geotextile fabric such that any pair of adjacent layers of geotextile fabric is separated by a layer of coarse-grained geological material. The permeable reactive barrier includes a perforated metal casing surrounding and containing the layers of coarse-grained geological materials and geotextile fabric.
