High-Contrast Colorless-to-Colored Thermochromic Materials. [PDF]
SmallWe developed new three‐component thermochromic systems showing reversible colorless‐to‐colored transition. Our general empirical rule applies to diverse fatty acid phase change materials and leuco dyes, enabling easily tunable transition temperature and activated colors (blue, cyan, green, pink, grey). Solid particles of these materials were integrated

PCL Nanomodified Coating for the Protection of Thermochromic Prints on Packaging
Materials Proceedings, 2023 In the graphic industry, thermochromic inks are used primarily in the development of “smart” packaging for different applications, such as indicators of the product’s current temperature or an out-of-boundary temperature reading.

Indigo in the nanochannels of zeolite L : towards a new type of colorant [PDF]
, 2018 A host-guest based colorant was synthesized by intercalating indigo molecules into the nanochannels of zeolite L (ZL). Reductive washing thereby ensured the efficient and selective removal of non-intercalated indigo molecules.

Controlled Synthesis of Luminescent Xanthene Dyes and Use of Ionic Liquid in Thermochromic Reaction
Molecules, 2022 In this study, we demonstrate six novel xanthene derivatives and their spectroscopic and chemical properties. The presented synthesis examination allowed us to obtain two different compounds during one step, with open and closed lactone rings substituted

A comparison of enhancement techniques for footwear impressions on dark and patterned fabrics [PDF]
, 2013 The use of chemical enhancement techniques on porous substrates, such as fabrics, poses several challenges predominantly due to the occurrence of background staining and diffusion as well as visualisation difficulties.

Synthesis and properties of Co-doped titanate nanotubes and their optical sensitization with methylene blue [PDF]
, 2013 Here we report on a novel chemical route to synthesize homogenous cobalt doped titanate nanotubes (CoTNT), using an amorphous Co-doped precursor. The influence of the synthesis temperature, autoclave dwell time and metal doping on the structural and ...
