Hydrogels that degrade under appropriate conditions of pH and temperature by virtue of crosslinking compounds that cleave through an elimination reaction are described. The hydrogels may be used for delivery of various agents, such as pharmaceuticals.

Disclosed is AA′ graphite with a new stacking feature of graphene, and a fabrication method thereof. Graphene is stacked in the sequence of AA′ where alternate graphene layers exhibiting the AA′ stacking are translated by a half hexagon (1.23 Å). AA′ graphite has an interplanar spacing of about 3.44 Å larger than that of the conventional AB stacked graphite (3.35 Å) that has been known as the only crystal of pure graphite. This may allow the AA′ stacked graphite to have unique physical and chemical characteristics.

The seal made between two surfaces is enhanced by forming a coating, such as a self-assembled monolayer of a functionalized fluorinated macromolecule, on one or both of the surfaces.

A stabilized elementary metal structure is disclosed. The stabilized elementary metal structure may include an elementary metal having at least one layer and having a two-dimensional layer structure, and an organic molecular layer provided on at least one of a top surface and a bottom surface of the elementary metal.

An electrically conductive component, which can be used in motor vehicles, may include a surface having a layered covering. The layered covering may be a melted and cured product of coating with a powder composition. Further, the layered covering may have a layer thickness of greater than 150 μm, and the layered covering may be a single-layer covering. The layered covering may also include a pore-like layer structure. The pore-like layer structure of the layered covering may be responsible for an at-least-15% reduction in density of the layered covering relative to a density of the layered covering without the pore-like layer structure.

A large-area monolayer of solvent dispersed nanomaterials and method of producing same is provided. The method includes dripping a nanomaterial solvent into a container filled with water whereby the nanomaterial being dripped collects at the air-water interface to produce the large-area monolayer. In one embodiment, different nanomaterial solvents can be dripped, at predetermined intervals such that the resulting large-area monolayer includes at least two different nanomaterials.
