The characterization of disperse dyes in polyester fibers using DART mass spectrometry

Journal of Forensic Sciences, Volume 67, Issue 6, Page 2291-2298, November 2022., 2022
Abstract Textile fibers alone are highly prevalent in our environment, and not only are there a wide variety of fibers, but generally, consumer textiles are colored. Given the variety of crime locations where dyes are encountered and the potential circumstances, a rapid, preparation free analysis of samples is highly beneficial.

Variability of a Non-Centrosymmetric Tecto-Borosulfate: Introduction of Various Molecular Cations into BiX[B(SO₄)₂]₄ (X  =  H₃O⁺, NO₂ ⁺, NH₄ ⁺, NO⁺). [PDF]

Chemistry
To date, Bi(H3O)[B(SO)2]4 is only the second structure type containing a 3D anion within borosulfate chemistry. In this contribution three more representatives were synthesized, formally replacing oxonium by the molecular cations nitrosonium, nitronium, and ammonium. The structures crystallize homeotypically to the very first compound.

Investigation into the reaction of reactive dyes with carboxylate salts and the application of carboxylate‐modified reactive dyes to cotton

Coloration Technology, Volume 138, Issue 1, Page 58-70, February 2022., 2022
Abstract Ink‐jet printing of cellulosic fabrics with reactive dyes typically requires that the fabric is pretreated with alkali, prior to printing, to facilitate efficient fixation of the dye. In this paper we evaluate the use of sodium formate and other carboxylate salts as a neutral (pH 6.5) pretreatment process. The thickened, prepared‐for‐print pad

Application Limits of the Ferrioxalate Actinometer**

ChemPhotoChem, Volume 5, Issue 10, Page 947-956, October 2021., 2021
Motivated by systematic measurement inconsistencies, ferrioxalate actinometry was experimentally investigated for the reason. A drop of the quantum yield at too high irradiation intensities was identified and explained in line with recent spectroscopic findings.
