An object is to provide a graphite sheet having excellent peelability from a slightly adhesive film. The object is attained by a method for producing a graphite sheet having a thermal diffusivity of not less than 8.0 cm.sup.2/s and an interlaminar strength of not less than 100 gf/inch, the method including the step of heat-treating a polyimide film to a temperature of not lower than 2,400° C., the polyimide film containing: not less than 0.05% by weight and not more than 0.30% by weight of inorganic particles; and a non-metal additive containing not less than 0.055% by weight and not more than 0.097% by weight of phosphorus.

An object is to provide, with high productivity, a graphite sheet having good thermal diffusivity and interlaminar strength. The object is attained by a method for producing a graphite sheet having a thermal diffusivity of not less than 10.0 cm.sup.2/s, the method including the step of heat-treating a polyimide film to a temperature of not lower than 2,800° C., the polyimide film containing: not less than 0.01% by weight and not more than 0.08% by weight of inorganic particles; and a non-metal additive containing not less than 0.018% by weight and not more than 0.032% by weight of phosphorus.

Disclosed are composite filaments for 3D printing. The filaments typically have high strength, an appropriate resorption rate, and high biocompatibility. The filaments generally contain a matrix formed of a blend containing a bioresorbable polymer and an inorganic component. The filaments can be used to produce customized scaffolds for repairing bone defects following implantation in the site of the defect. The shape and size of the scaffold can be configured to fit in and conform to the bone defect. The scaffolds are especially useful in repairing critical sized bone defect, such as a critical sized bone defect in a weight-bearing long bone.

The invention features adhesive devices for holding objects (e.g., bone fragments) fixed with respect to each other.

Provided herein is technology relating to materials having microscale and/or nanoscale features and particularly, but not exclusively, to porous materials comprising microscale features, methods for producing porous materials comprising microscale features, drug delivery vehicles, and related kits, systems, and uses.

A camera module containing a molded part (e.g., generally planar base, lens barrel mounted on the base, etc.) that is formed from a polymer composition is provided. The polymer composition includes a liquid crystalline polymer and inorganic particles that have a hardness value of about 2.5 or more based on the Mohs hardness scale.

The present invention relates to a thermally activatable adhesive composition for use in a method for producing a stack of metal sheets from glued together sheet metal components, the use of the adhesive composition in a method for producing a stack of metal sheets from glued together sheet metal components, the method for producing a stack of metal sheets from glued together sheet metal components, a sheet metal component coated with the adhesive composition, and a stator or rotor core containing one or more of such sheet metal components.

A biocompatible composite material for controlled release is disclosed, comprising a biocompatible metal oxide structure with a loaded network of pores. The pore network of the biocompatible composite material is filled with a uniformly distributed biologically active micellizing amphiphilic molecule, the size of these pores ranging from about 0.5 to about 100 nanometers. The material is characterized in that when exposed to phosphate-buffered saline (PBS), the controlled release of the active amphiphilic molecule is predominantly diffusion-driven over time.

This invention is directed to composites and films comprising hydroxyapatite, biodegradable polymer, a biocompatible surfactant with inorganic fullerene-like (IF) nanoparticles or inorganic nanotubes (INT); methods of preparation and uses thereof.
