Influence of Cotton Cationization on Pigment Layer Characteristics in Digital Printing

open access: yesMolecules, 2022
The paper examines the influence of cotton cationization on the print quality in terms of penetration, colour yield and colour depth, which have been analysed in comparison to cotton untreated and pretreated with conventional acrylate binder. The process

Síntese de pigmentos cerâmicos por precipitação química Synthesis of ceramic pigments by chemical precipitation

open access: yesCerâmica, 2007
Os pigmentos cerâmicos são substâncias capazes de desenvolver cor em sólido inorgânico (cerâmica ou vidro) quando nele dispersar mantendo-se insolúvel no mesmo, sem reação química com o mesmo, nas elevadas temperaturas de processamento.

A pigmented octogenarian [PDF]

open access: yesAge and Ageing, 2010
An 81-year-old woman presented with cachexia, malaise, deranged liver function tests (LFTs), hepatomegaly and hyperpigmentation. Hereditary haemochromatosis (HH) was ultimately diagnosed on genetic testing. Haemochromatosis is a difficult diagnosis in older people because not only are the symptoms protean and occur commonly in other geriatric ...

Studies of pigment transfer between Xenopus laevis melanophores and fibroblasts in vitro and in vivo

open access: yes, 2006
Frog melanophores rapidly change colour by dispersion or aggregation of melanosomes. A long-term colour change exists where melanosomes are released from melanophores and transferred to surrounding skin cells.

Serum zinc level in vitiligo: A case-control study

open access: yesIndian Journal of Dermatology, 2018
Background: Vitiligo is characterized by the idiopathic destruction of melanocytes, probably of autoimmune etiology, that results in depigmented patches of skin and mucosal surfaces. Oxidative stress may contribute to the pathogenesis of vitiligo.

Electro-Optical Effects of a Color Polymer-Dispersed Liquid Crystal Device by Micro-Encapsulation with a Pigment-Doped Shell

open access: yesCrystals, 2019
Polymer-dispersed liquid crystals (PDLCs) refer to nematic liquid crystals, which are embedded in a polymer matrix. A conventional PDLC device is fabricated by phase separation. However, this method leads to non-uniform electro-optical characteristics of
