Abstract: Disclosed is a media element including an environmental indicator material configured, in response to exposure to a predetermined environmental condition, to change from an initial state to a second state producing an observable effect. The media element further includes a plurality of microcapsules, each microcapsule encapsulating the environmental indicator material in a non-activated configuration and releasing the environmental indicator material when ruptured. The microcapsules prevent an occurrence of the observable effect while in the non-activated configuration and allow the occurrence of the observable effect when the environmental indicator material is exposed to the predetermined environmental condition after at least a portion of the plurality of microcapsules are ruptured. The media element further includes a bursting additive proximate the plurality of microcapsules. The bursting additive selectively interacts with the plurality of microcapsule to rupture the plurality of microcapsules when a force is applied to the plurality of microcapsules and bursting additive.

Abstract: A smart sticker for determining the current state of raw meat for safe human consumption is provided. The smart sticker indicates the quality or decomposition of the meat by changing color. The smart sticker employs a cupric nitrate solution mixed with a polymeric silicon substrate that forms a complex with the valence electrons on the nitrogen atom of an amino acid residue. After this interaction occurs, the smart sticker changes color from, for example, light blue to purple.

Abstract: An application for a neonatal calorimetric carbon dioxide detector has a calorimetric carbon dioxide detector membrane having a pH-sensitive chemical indicator that undergoes calorimetric change in the presence of carbon dioxide. The detector has a patient orifice in fluid communication with the baby's airway and a respiration equipment orifice connected to a breathing system. The patient orifice is connected to a breathing tube and when the breathing tube is inserted correctly into the trachea, as the baby exhales, carbon dioxide interacts with the calorimetric membrane which changes color based upon the concentration of carbon dioxide. The neonatal calorimetric carbon dioxide detector adds a volume of less than or equal to 1 mL after being attached to a breathing circuit.

The ratiometric fluorescent pH sensors comprise a fluorescent dye that exhibits a shift in excitation wavelength with a corresponding shift in pH in the local environment of said fluorescent dye. Ratiometric measurements of the emission intensities at dual excitation maxima correlate to pH. Also provided is a fluorescent dye 6-methacryloyl-8-hydroxy-1,3-pyrene disulfonic acid (MA-HPDS). Further provided are systems and methods to non-invasively and continuously monitor pH.

Abstract: A diffusion sample collector for gaseous media, consisting of a transparent container open at both ends, which contains a collecting layer and has at its two open ends permeable retaining elements. The collector is improved in such a manner that the presence of hazardous substances in the surrounding air to be analyzed can be recognized during the collecting of the samples in order that an unnecessary analysis of the collecting layer can be prevented in the absence of hazardous substances and also gas eruptions can be noticed immediately. For this latter purpose, an additional layer is provided in the container, which is separated from the collecting layer by a dividing wall and is in contact with the gas to be analyzed through the opposite end and its retaining element.
