Abstract: The purpose of the present invention, relating to lanthanide boride, which is known as a low work function material, is to provide a novel low work function material with low chemical reactivity, in particular a low work function material of which the material surface, after being exposed to atmospheric gases, can be cleaned at a heating temperature lower than in the prior art. The present invention is a laminate containing a lanthanide boride film formed on a substrate, the surface of said film being covered by a thin film, wherein the thin film is a monatomic layer of a hexagonal boron nitride thin film.

Abstract: An objective of the present invention is to provide a method for manufacturing a soft ocular lens in which the surface of the lens is hydrophilized by means of plasma processing, wherein a substrate surface can be sufficiently hydrophilized by performing, once, a reaction between the substrate and a hydrophilic polymer. Another object of the present invention is to provide a soft ocular lens with sufficient hydrophilicity which comprises only one layer comprising a hydrophilic polymer on a substrate surface. A substrate comprising a hydrocarbon group-containing polysiloxane is subjected to plasma processing with an inert gas such as nitrogen, to form a radical including Si—CH2 on the substrate surface, and produce radical rearrangement with a hydrophilic polymer, thereby causing the hydrophilic polymer to bind to the substrate surface by recombination of a radical generated in the hydrophilic polymer with the substrate.

Abstract: This method for analysis processing by using measured impedance spectrum data includes: a step for determining whether to reset the maximum value and/or the minimum value of logarithmic relaxation time corresponding to a measured logarithmic frequency on the basis of the measured impedance spectrum data; a step for setting the number of equal-interval divisions within the range of the logarithmic relaxation time set in the determination step; and a step for analyzing parameters R∞, T, L, and Rl for the range of the set logarithmic relaxation time so as to satisfy a prescribed expression (A) by applying a regularized least-squares method.
