Abstract: An orthosis according to an embodiment has a first region and a second region. The first region is constituted with a first unit cell structure that is a unit cell structure in which a space of a polygonal prism shape is defined as one unit, and includes a plurality of structural columns connecting two points among a plurality of vertices forming the polygonal prism shape. The second region is constituted with a second unit cell structure different from the first unit cell structure. The first unit cell structure and the second unit cell structure include at least one structural column connecting a certain. vertex among the plurality of vertices and another vertex different from a vertex on a side including the certain. vertex.

Abstract: As shown by the following formula (1), after methyl laurate (2 mmol) and water (8 mL) are added to an ammonium pyrosulfate catalyst (5 mol %), a hydrolysis reaction of methyl laurate is carried out by heating for 24 hours at 60° C. while stirring is performed, so that lauric acid can be obtained with a yield of 86%.
