The modification of sand with superhydrophobic silica/wax nanoparticles may provide for water storage, applicable, for example, in desert environments. In particular, highly thermal stable superhydrophobic coats for sand are made of nanoparticles composed of superhydrophobic silica capped with paraffin wax. Superhydrophobic sand modified by such nanoparticles addresses issues of water storage in desert environments, capitalizing on sand resource utilization. Superhydrophobic sand, as modified, has excellent water repellency and great water-holding capacity. The superhydrophobic sand modified with superhydrophobic silica/wax nanoparticles can be applied for the desert water storage for agriculture and planting.

The conductive adhesive layer contains a cured product of an epoxy resin and a carboxyl group-containing elastomer, an organic phosphorus-based flame retardant, and a conductive filler; the metal layer has a thickness of from 0.3 m to 7 m; and a conductive adhesive forming the conductive adhesive layer contains 10 parts by weight to 50 parts by weight of the organic phosphorus-based flame retardant and 10 parts by weight to 80 parts by weight of the conductive filler with respect to 100 parts by weight of a total of the epoxy resin and the carboxyl group-containing elastomer.

The present invention relates to the field of environmental pollution remediation technology, in particular to a nanocomposite preparation and a method for making the same and use thereof. The nanocomposite preparation provided herein includes a nanomaterial and an extracellular polymeric substance (EPS) solution of a microorganism, where the nanomaterial is graphene oxide (GO) or multi-walled carbon nanotubes (CNT); and the microorganism is Paracoccus aminovorans HPD-2, deposited in China General Microbiological Culture Collection (CGMCC) Center, with a deposition number of CGMCC No. 2568. The nanomaterial and EPS system in the present disclosure may improve the bioeffectiveness of Polycyclic Aromatic Hydrocarbons (PAHs) in soil and thus the degradation of PAHs compared to a single system. The synergistic effect between the nanomaterial and the EPS of the degrading bacteria significantly improves the removal of PAHs from soil and water, thus greatly reducing the remediation cycle of the PAH-contaminated soil and water.
