Abstract: A thermochromic indicator and its use for visually determining whether adjacent surfaces of overlapping edge portions of side-by-side roofing membrane segments have been sufficiently heated to a preselected temperature threshold to achieve a desired weld therebetween to correspondingly seal the roofing membrane seam.

Abstract: Disclosed herein are embodiments of (i) a novel stabilizer including a stable nitroxide free radical which can function as a light-stabilizer and/or a heat-stabilizer, and (ii) compositions including the stable nitroxide free radical.

Abstract: A temperature sensor, and methods of making and using such a temperature sensor, whereby the temperature sensor includes a reversible thermochromic color-changing system having a dye, a developer, and a solvent. Upon exposure to a preselected temperature threshold, association or disassociation of the dye and the developer results in a visible color change. Further, the color-changing system includes a color-memory property which facilitates retention of the color change to effectively record exposure to the temperature threshold.

Abstract: The design, synthesis, and functionalization of a conjugate including a tumor-targeting near-infrared (NIR) dye and a therapeutic agent and/or a diagnostic agent, whereby the NIR dye can function to target the therapeutic agent and/or diagnostic agent to tumor cells.

Abstract: A pressure sensor and its use for visually determining whether a preselected pressure threshold has been achieved, for example during high pressure processing treatment of a foodstuff. The pressure sensor includes a contained color-changing system having a dye, a developer, and a solvent; upon achievement of the preselected pressure threshold, the dye and the developer interact, resulting in a visible color change. Further, the visible color change can be retained upon a decrease in pressure and upon an increase in temperature, thereby effectively recording the achievement of the preselected pressure threshold during the high pressure processing treatment.

Abstract: A new leuco dye produces a yellow color while demonstrating also exceptional light and thermal stability under light.

Abstract: A red leuco dye demonstrates unusually good thermal and photo stability. The red dye may be used with developers and wax carries for microencapsulation to form thermochromic pigments for use in inks, coatings and the like. This pigment is particularly desirable for use in metal-deco coatings, such as those used in aluminum cans in high beverage canning operations.

Abstract: Described are novel photochromic naphthopyran compounds which exhibit a red coloring when in a red-colored state achieved upon exposure to ultraviolet light, whereby the red coloring has a lambda max in a range of between about 490 nanometers to about 510 nanometers or between about 490 nanometers to about 500 nanometers.

Abstract: The present invention relates to a loaded particle comprising at least one fluorescent dye, and in particular, a fluorescent dye with a large Stokes shift. The invention further relates to a method for producing an loaded latex particle, loaded with a fluorescent dye having a large stokes shift. In addition, the present invention relates to latex particles loaded with fluorescent dyes that are organic solvent soluble and insoluble in water. In a preferred embodiment, when the dyes are loaded into the water soluble latex particle, an increase is observed in quantum yield of fluorescence as compared to the quantum yield of the dye in aqueous solvent.
