A structure having a substrate, a radiation patternable organometallic coating composition, and a radical scavenging additive is also described. The radical scavenger additive or a blend thereof can result in patterning improvements, such as by improving coating quality and reducing patterning variability. Methods of using a radical scavenging additive in the formation of a structure comprising a radiation patternable organometallic film are described.

Abstract

The present invention provides: a composition and a food/beverage item which can promote the elongation of pili of an intestinal bacterium and exhibits an anti-bacterial activity; and a method for assisting the examination and diagnosis of a disease caused by a pathogenic bacterium or a pathogenic fungus. The present invention provides a composition containing a bacterium capable of producing 3-phenylpropionic acid (PPA) or 3-(4-hydroxyphenyl)propionic acid (4OHPPA). The present invention also provides a food/beverage item containing PPA or 4OHPPA. The present invention further provides a method for assisting the examination and diagnosis of a disease caused by a pathogenic bacterium or a pathogenic fungus. The method comprises: quantifying the amount of PPA or the amount of 4OHPPA in feces from a subject by using 2-nitrophenylhydrazine; and comparing a value obtained by the quantification of the amount of PPA or the amount of 4OHPPA with a reference value. When the value obtained by the quantification of the amount of PPA or the amount of 4OHPPA is smaller than the reference value, it is determined that the subject is possibly affected by the disease.

Abstract

Provided are: thermoplastic polymer foamed particles in which it is possible to identify the foamed particles themselves; and a thermoplastic polymer foamed particle molded body that, by being formed from the identifiable thermoplastic polymer foamed particles, can be identified without ruining the aesthetics thereof. Further provided is an identification method for the thermoplastic polymer foamed particles and/or the thermoplastic polymer foamed particle molded body. Thermoplastic polymer foamed particles (100) exhibit a light emission reaction derived from a light-emitting rare-earth element (10) through irradiation with electromagnetic waves. This thermoplastic polymer foamed particle molded body is formed through in-mold molding using the thermoplastic polymer foamed particles (100) and thereby exhibits a light emission reaction. This identification method for the thermoplastic polymer foamed particles or the thermoplastic polymer foamed particle molded body comprises: i) an electromagnetic wave irradiation step for irradiating the surfaces of the thermoplastic polymer foamed particles or the thermoplastic polymer foamed particle molded body with electromagnetic waves; and ii) a detection step for detecting, by using a detection device, a light emission reaction that is derived from a light-emitting rare-earth element and that occurs through the irradiating with the electromagnetic waves to obtain a light emission spectrum. A first method of the identification method further comprises iii-1) an identification step for observing the contrast between the light emission spectrum and a blank spectrum in which the light emission reaction derived from the light-emitting rare-earth element is not exhibited. A second method of the identification method further comprises iii-2) an identification step for comparing the light emission spectrum with a preset standard light emission spectrum in which the light emission reaction derived from the light-emitting rare-earth element is exhibited.
