The present invention is a unique process of manufacturing rigid members with precise “shape keeping” properties and with reflective properties pertaining to radio frequency energy, so that air, land, sea and space devices or vehicles may be constructed including parabolic reflectors formed without discrete permanent layering. Rather, such parabolic reflectors or similarly, vehicles, may be formed by homogeneous construction where discrete layering is absent, and where energy reflectivity or scattering characteristics are embedded within the homogeneous mixture of carbon nanotubes and associated graphite powders and epoxy, resins and hardeners. The mixture of carbon graphite nanofiber and carbon nanotubes generates higher electrode conductivity and magnetized attraction through molecular polarization. In effect, the rigid members may be tuned based on the application. The combination of these materials creates a unique matrix that is then set in a memory form at a specific temperature, and then applied to various materials through a series of multiple layers, resulting in unparalleled strength and durability.

The invention relates to a method for forming an article comprising a pathway of particles wherein a termination of the pathway of particles is exposed. The method comprises arranging the particles by applying an electric field and/or a magnetic field at an interface between a water soluble or a non-water soluble matrix and a matrix comprising a viscous material and particles. After fixating the viscous material, the termination is exposed by dissolving the water soluble or non-water soluble matrix. The invention also relates to articles obtainable by said method, and to the use of said method in various applications.

A water-soluble film includes a polyvinyl alcohol resin (A) as a main component, wherein the ratio (X.sub.TD/X.sub.MD) of a degree of elongation (X.sub.TD) in the transverse direction (TD) of the water-soluble film to a degree of elongation (X.sub.MD) in the machine direction (MD) thereof when the water-soluble film is floated on the surface of water at 20° C. for 60 seconds is from 1.05 to 1.5. The water-soluble film exhibits reduced curling, exhibits reduced positional shift, and shows satisfactory sealability while forming a package.

Provided is a microneedle patch comprising a substrate part and multiple needle parts protruding from the substrate part. The substrate part consists of a diffusion-proof layer and a base, and each needle part consists of a needle tip, a diffusion-proof layer and a base. The diffusion-proof layer of each needle part is formed between the needle tip and the base of the corresponding needle part. The diffusion-proof layer of the substrate part and the diffusion-proof layer of needle part are one-piece structures, and so are the base of the substrate part and the base of the needle part. The diffusion-proof layer of the microneedle patch can prevent the active ingredients from diffusing to the base, limit the active ingredients to the needle tip and control the carrying quantity thereof.

The present invention relates to a method for manufacturing polylactide-based articles by rotational molding and also to the articles obtained by the method.

The method, characterized in that, the powdered chitosan is dissolved in water to obtain a 5% solution, into which a 70-90% acetic acid is added and after the formation of the blank intramedullary nail and carrying a coagulating bath and neutralization bath it is subjected to a crosslinking bath in a solution formed from 0.5 to 2% of sodium tri-polyphosphate and 0.5% to 3% Na3PO4 for 24 to 48 hours in temperature of 50° C. to 140° C. and then it is subjected to the drying process, for a period of 6 to 10 days, and finally the surface of the blank is treated to form the intramedullary nail. The surface treatment is carried out until the surface of the intramedullary nail contains at least 20%-40% of the pore of the depth of 0.1 mm to 1 mm.
