X-ray Visualization and Quantification Using Fibrous Color Dosimeter Based on Leuco Dye

Applied Sciences (Switzerland), 2020
A polystyrene (PS)-based fibrous color dosimeter, comprising a color former based on 2-(phenylamino)-6-(dipentylamino)-3-methylspiro[9H-xanthene-9,3′-phthalide] (Black305) fluoran leuco dye and a 2-(4-methoxystyryl)-4,6-bis(trichloromethyl)-1,3,5 ...

Electrospun microfibers with embedded leuco dye-based thermochromic material for textile applications

Journal of Industrial Textiles, 2022
Electrospinning is an inexpensive and versatile technique for fabricating micro- and nano- scaled fibers. There have been limited attempts to employ it for the fabrication of thermochromic (TC) fibers, and the fabrication of a three-component (dye ...

Relation between colour- and phase changes of a leuco dye-based thermochromic composite. [PDF]

Sci Rep, 2018
AbstractReversible colour change of leuco dye-based composites is in general closely related to their phase change, thus the two phenomena should occur at around the same temperature and should be influenced similarly. However, spatial confinement of the analysed sample affects the change in colour differently compared to its phase transition and the ...

The Effect of Temperature on Thermochromic Leuco Dyes: A Meta-Analysis

Journal of Applied Agricultural Science and Technology
The effect of temperature treatment, either increasing or decreasing the temperature of leuco dyes, can produce thermochromic by looking at the changing color of samples resulting from experiments. The colors that are seen namely brightness (L), a* value,

Design and Synthesis of Red-Absorbing Fluoran Leuco Dyes Supported by Computational Screening. [PDF]

ACS Omega
We report here on the design and synthesis of red-absorbing fluoran leuco dyes (LD). An essential part of the present dye development process is a computational screening of the candidate molecules, which allows for both time-efficient and accurate in silico characterization of the dyes.

Dye-sensitized Solar Cells Based on Fluoran Leuco Sensitizers

Journal of the Korean Institute of Electrical and Electronic Material Engineers, 2013
The utilization of a fluoran leuco sensitizer, 2-anilino-6-dibutyl amino-3-methylfluoran (ODB-2), for dye-sensitized solar cells (DSSCs) was investigated through the examination of the adsorption of ODB-2 molecules onto the surfaces of porous titanium dioxide (titania, TiO2) films and the photovoltaic properties of ODB-2-based DSSCs.

Irreversible temperature indicator based cellulose membranes conjugated with leuco‐dye pigment

Journal of Applied Polymer Science
AbstractThis research focuses on the development of thermochromic membranes made of cellulose acetate (CA) for temperature monitoring of sensitive food products. Two dual TC membranes developed for the control of different temperature ranges were formulated using a three‐component system: a leuco‐dye membrane (crystal violet lactone, CVL) integrated ...

The Biotransformation and Biodecolorization of Methylene Blue by Xenobiotic Bacterium Ralstonia pickettii

Indonesian Journal of Chemistry, 2021
The biotransformation and biodecolorization of methylene blue (MB) dye using the bacterium Ralstonia pickettii was investigated. This experiment was conducted in a nutrient broth (NB) medium after adding MB at 100 mg L–1 concentration.

Sensitivity Optimization for a New Radio-Chromic Dosimeter (PRESAGE) [PDF]

Iranian Journal of Medical Physics, 2010
Introduction: Different dosimetric modalities (e.g., ionization chambers, semiconductors, TLDs, radiographic films) often have some problems determining isodose curves and percentage depth doses in high dose gradient regions. Research has been ongoing to
