Abstract: An autonomous driving device module mounting structure includes: a floor panel that constitutes a part of a vehicle body and extends in a front to rear direction of a vehicle and a width direction of the vehicle; a rear seat that is disposed on a vehicle upper side of the floor panel such that a gap is formed with respect to the floor panel; and an autonomous driving device module that is equipped with a plurality of devices and is disposed on the vehicle upper side of the floor panel and a vehicle lower side of the rear seat.

Abstract: A modified metal oxide particle material includes: a metal oxide particle material having, on a surface thereof, a functional group other than a phenyl group; and a modifying material formed of a silicon-containing compound having a phenyl group. The modifying material is adhered to the surface of the metal oxide particle material. When the modified metal oxide particle material is washed with methyl ethyl ketone, a ratio (C/H) of a carbon content C (% by mass) to a surface area H (m2) per 1 g is 0.05 or less, after the washing. The ratio (C/H) is reduced by 0.1 or more, and the modifying material is removed by 50% or more by mass, after the washing compared with before the washing.

Abstract: A particle material that has high dispersibility in a dispersion medium such as toluene having high hydrophobicity, and a slurry composition in which the particle material is used, are provided for solving the problem. A surface-modified particle material of the present invention includes: a particle material formed of an inorganic material; and a surface treatment agent formed of a silane compound having a first functional group that has any of C, N, and O atoms away over five or more atoms from Si to which an alkoxide is bound, the surface treatment agent allowing surface treatment of the particle material in such an amount that a degree of hydrophobicity becomes not less than 30%. Dispersibility is enhanced also in a dispersion medium having high hydrophobicity in a case where a functional group having a predetermined structure is introduced so as to impart predetermined or higher hydrophobicity.
