Abstract: A dispersion for an X-ray target in which gold nanoparticles and sodium alginate or a calcium phosphate-based bone reinforcing material are dispersed, in which the gold nanoparticles are in contact with the sodium alginate or the calcium phosphate-based bone reinforcing material.

Abstract: A cable wherein it is possible to prevent a pair of conductors from coming into contact with one another by disposing an inner insulator between the pair of conductors, and to prevent damages to a power source circuit and such caused by the flow of overcurrent. A cable (100) is used when supplying power to a storage battery on a moving body. A first conductor (101) is connected to a positive electrode. A second conductor (102) is connected to a negative electrode. A third insulator (106) is disposed between the first conductor (101) and the second conductor (102), thereby preventing the first conductor (101) and the second conductor (102) from coming into contact with one another. A fourth insulator (107) covers the first conductor (101), the second conductor (102), and the third insulator (106).
