Photochemical colour change for traditional watercolour pigments in low oxygen levels [PDF]
, 2015 An investigation for light exposure on pigments in low-oxygen environments (in the range 0–5% oxygen) was conducted using a purpose-built automated microfadometer for a large sample set including multiple samples of traditional watercolour pigments from ...

Novel Electrochemical Lactate Biosensors Based on Prussian Blue Nanoparticles
Engineering Proceedings, 2023 We report on the novel electrochemical lactate biosensors based on Prussian blue nanoparticles. The immobilization of lactate oxidase was performed through drop-casting on the sensor surface of a mixture containing enzyme, (3-aminopropyl)triethoxysilane ...

Prussian Blue Analogues of Reduced Dimensionality [PDF]
Small, 2012 AbstractMixed‐valence polycyanides (Prussian Blue analogues) possess a rich palette of properties spanning from room‐temperature ferromagnetism to zero thermal expansion, which can be tuned by chemical modifications or the application of external stimuli (temperature, pressure, light irradiation). While molecule‐based materials can combine physical and

Strategies for synthesis of Prussian blue analogues [PDF]
Royal Society Open Science, 2021 We report a comparison of different common synthetic strategies for preparation of Prussian blue analogues (PBA). PBA are promising as cathode material for a number of different battery types, including K-ion and Na-ion batteries with both aqueous and non-aqueous electrolytes. PBA exhibit a significant degree of structural variation.

Blue in Eighteenth-Century England: Pigments and Usages
XVII-XVIII, 2018 This paper seeks to explore the materiality of the colour blue in eighteenth-century England, with a focus on indigo and Prussian blue – pigments that dominated the eighteenth-century blue colourant market either qualitatively, quantitatively, or both ...
