Fire retardant polyisocyanurate foam [PDF]
Fire retardant properties of low density polymer foam are increased. Foam has pendant nitrile groups which form thermally-stable heterocyclic structures at temperature below degradation temperature of urethane ...

Chromium and Cobalt in Used Leather Items: A Danish Market Survey
Used leather items from the Danish second‐hand market frequently release chromium(VI) and, in some cases, cobalt. Some items exceed current EU limits, highlighting a persistent but underrecognised source of exposure in the circular economy that may contribute to ongoing contact allergy despite existing regulations.

The plasticisation model of dye diffusion: Part 8
Abstract Re‐evaluation using the Williams–Landel–Ferry equation, of exhaustion/rate of dyeing/fixation data previously reported for and acid dye, natural dye and two reactive dyes on three different types of silk substrate revealed that thermally activated dye diffusivity is governed by the thermally regulated structural relaxation times of the ...

Abstract The instability of anthocyanins limits their application as natural food colorants. This study aimed to enhance the stability of anthocyanins extracted from Hibiscus sabdariffa through copigmentation with protein nanofibrils produced from pea, rice, gluten and whey isolates. Linear and curly nanofibril structures were prepared and incorporated

Abstract This study evaluated the impact of in‐office bleaching on color stability of bulk‐fill composites submitted to staining. Bulk‐fill (Aura, Opus, and Filtek One) and nanofilled (Filtek Z350) composite specimens were submitted to the following: control (CT); bleaching and immersion in distilled water (BL); and bleaching with daily 15‐min ...

Effect of pH on recovery efficiency and anthocyanin composition of <i>Clitoria ternatea</i> extracts with application as lipid antioxidants in food preservation. [PDF]
pH significantly affects the extraction efficiency of TPC TAC and the extracted anthocyanin components. pH 3 and pH 7 yield the highest extraction efficiency and antioxidant activity. Extracts at pH 7 are suitable as blue color additives for neutral pH foods and as good antioxidants for fat‐containing gummies.
