Abstract: The present disclosure relates to compositions derived from bioreachable molecules, such as amino acids and/or steroids. In particular, the composition can be a monomer, a polymer, or a copolymer derived from an amino acid dimer. Such compositions can optionally include a functionalized steroid.

Abstract: A method for producing a molded body is provided. The molded body is made of a thermoplastic material and can be produced in a short molding cycle. The method includes a step of compressing a molding precursor including a thermoplastic resin between a pair of molding dies having an insulation site at a surface that comes into contact with the molding precursor, in order to obtain a molded body. The temperature TA of the molding precursor at the start of compression satisfies the following Formula 1: E?(?100)×0.04<E? (TA)<E?(?100)×0.13. The temperature TB of the pair of molding dies at the start of compression satisfies the following Formula 2: E?(?100)×0.3<E?(TB)<E?(?100)×0.7. The insulation site has a heat conduction coefficient of 5 W/(m·K) or less, and the surface that comes into contact with the molding precursor has a dynamic friction coefficient of 0.25 or less.

Abstract: A ceramic heater including a columnar substrate and a heat generation resistor embedded in the substrate. A taper surface (12) having a contour L1 extending along an imaginary ellipse E is composed of a plurality of successively arranged curved surfaces which decrease in radius of curvature toward the forward end with respect to the direction of an axis P. The taper surface (12) is such that the distance between the end points M1 and M2 of the contour L1 is large in the direction of the axis P, and the angle between the axis P and a tangential line of the contour L1 on the side toward the forward end surface (11) is larger than the angle between the axis P and a tangential line of the contour L1 on the side toward the side circumferential surface (15).

Abstract: There are provided a ceramic heater in which a defect, such as generation of a gap at the interface between an insulating substrate and a heat-generating resistor, is unlikely to occur in the course of manufacture or use, and a glow plug using the ceramic heater. A ceramic heater 110 includes an insulating substrate 111 extending in the direction of an axis AX and a heat-generating resistor 115, which has a heat-generating portion 116, two lead portions 117, 117 and two lead lead-out portions 118a and 118b. The ceramic heater 110 satisfies an expression S1?0.34 Sa, where Sa is the area of a cross section of the ceramic heater 110 taken perpendicular to the direction of the axis AX, and S1 is the total cross-sectional area of the two lead portions 117, 117 as measured in the cross section.

Abstract: A method for producing a metal oxide thin film (70) includes a plating process in which a methyl-ketone-based organic solution (20) containing dimethyl sulfoxide and halogen is used as a plating solution. Using such an organic solution, which is corrosive, as the plating solution, a thin film of non-water-soluble metal oxides can be formed. Further, owing to the halogen and dimethyl sulfoxide contained in the organic solution, the formed metal oxide thin film has a high thickness uniformity and a high density.
