The present invention relates to a dry reforming catalyst in which an active material is impregnated on the surface of a metal oxide support and the active material is surrounded by a surfactant, a method of preparing the same, and a method of producing a synthetic gas using the catalyst. Since the surfactant on the surface of the active material prevents the active material from being sintered and the active material surface from being covered with carbon, the dry reforming catalyst exhibits high activity at high temperature for a long period of time without having to use a precious metal, and thus is useful for the production of a synthetic gas.

Provide is a functional structural body that can suppress aggregation of metal oxide nanoparticles and prevent functional loss of metal oxide nanoparticles, and thus exhibit a stable function over a long period of time. A functional structural body (1) includes: a skeletal body (10) of a porous structure composed of a zeolite-type compound; and at least one type of metal oxide nanoparticles (20) containing a perovskite-type oxide present in the skeletal body (10), the skeletal body (10) having channels (11) that connect with each other, and the metal oxide nanoparticles (20) being present at least in the channels (11) of the skeletal body (10).

Disclosed are a method for creating a surgical training model, a surgical training model apparatus, a bone model, an article that emulates tissue of an animal musculoskeletal system, an article that emulates animal fat tissue, and an article that emulates animal skin tissue. One version of the method comprises placing a spinal vertebrae model in a cavity model that emulates an animal body cavity; forming a first layer on top of the vertebrae model, wherein the first layer emulates an animal muscle tissue; placing a second layer over the first layer, wherein the second layer emulates an animal fat tissue; and placing a third layer over the second layer, wherein the third layer emulates an animal skin tissue. The spinal vertebrae model can be 3D printed from a thermoplastic polymer and infiltrated with a foam into an interior space of the 3D printed spinal vertebrae model.
