Evaluating ion exchange resin efficiency and oxidative capacity for the separation of uranium(IV) and uranium(VI)

Geochemical Transactions, 2013
Background Previously described methods to separate dissolved U(IV) from dissolved U(VI) under acidic anoxic conditions prior to laboratory analysis were ineffective with materials currently available commercially. Three strong anion exchange resins were

NOVEL HUMAN HAIR DYES III Human Hair Dyeing by Leuco-naphthazarin

Sen'i Gakkaishi, 1989
Leuco-naphthazarin dyes white human hair fibers in an aqueous solution under the exceedingly mild conditions without any reducing agents and strong alkali in a dye bath at room temperature. The color development can be achieved without any oxidants. The dyeability remarkably increased by an addition of benzyl alcohol.

Grid‐Shaped, Vertically Aligned Carbon Nanotube Architectures for Electrical, Optical, and Mechanical Bolometers

Advanced Sensor Research, Volume 5, Issue 2, February 2026.
The small geometry of nano/micro sensor devices, down to 3 × 3 µm2, makes them ideal for reliable large‐scale integration into sensor arrays for single‐use biomedical, industrial, and security applications. These devices allow for the efficient conversion of ultraviolet to terahertz radiation into electrical or optical output signals using simple ...

The plasticisation model of dye diffusion: Part 4

Coloration Technology, Volume 142, Issue 1, Page 119-141, February 2026.
Abstract Previously published data reported for the temperature dependency of the diffusion of an organic acid within PA 6 film, as well as the desorption of three acid dyes from dyed nylon 66 fabric, diffusion of an acid dye within nylon 6 film and the adsorption of a sulphur dye onto nylon 66 fabric, over a diverse range of application/washing/dyeing

Potential Applications of Oxidoreductases for the Re‐oxidation of Leuco Vat or Sulfur Dyes in Textile Dyeing

Engineering in Life Sciences, 2008
AbstractConventional textile dyeing by vat and sulfur dyes includes reduction and re‐oxidation steps (with chemical reductants and oxidants), so that the insoluble dyes can be solubilized in the dyeing solution, adsorbed by the fabric, and fixed onto the dyed fabric.
