PRESAGE® is a solid radiochromic dosimeter consisting of a polyurethane matrix, a triarylmethane leuco dye, and a trihalomethane initiator. Varying the composition and/or relative amounts of these constituents can affect the dose sensitivity, post-irradiation stability, and physical properties of the dosimeter. This allows customisation of PRESAGE® to meet application-specific requirements, suc...

soluble vitamin and needed for the growth and repair of tissues in all parts of the body. AA has vital importance in processes of oxidation and reduction in human organism participating of several metabolic reactions. AA has also been used for the prevention and treatment of the common cold, mental illness, infertility, cancer and AIDS. Due to the great importance of AA in human beings, the qua...

Thermochromic printing inks could be security inks which respond to the color change when are being exposed to different temperatures. These inks with unusual chemical and physical specific characteristics are mostly produced for flexographic, screen and rotogravure printing systems under the supervision of skilled technical experts and with precise security controls. Since flexographic thermoc...

Photoactivatable “caged” fluorophores enable numerous advanced biological imaging experiments, including photoactivated localization microscopy (PALM) and related super-resolution imaging techniques. Of the extant fluorophore scaffolds, caged rhodamines and fluoresceins display properties that are exceptionally well suited for superresolution microscopy, exhibiting high contrast and photon yiel...
