Preparation of Cobalt Blue Ceramic Glaze Ink Based on Sol- Gel Method

Chemical Engineering Transactions, 2018
Cobalt blue pigment precursor xerogel was prepared by sol-gel method and then calcined to obtain cobalt blue pigment by self-propagating combustion. The effect of process parameters such as pH value, metal ion concentration, dispersant, sol reaction ...

Rheology of Titania Pigment Slurry

Applied Rheology, 2012
The influence of polymeric dispersants containing different functional groups on the suspension behaviour of titania pigment slurry was investigated. The dispersants chosen were polyacrylic acid and modified polyacrylamides including homo and copolymers ...

Noble aluminum-pigmented metallic polymers II: Effects of inorganic filler on weld- and flow-line visibility

Polymer Testing, 2022
Aluminum flakes, inorganic filler, and Acrylonitrile–butadiene–styrene (ABS) polymer were mixed to form noble aluminum-pigmented metallic polymers. The effects of inorganic filler on weld- and flow-line visibility were investigated using field-emission ...

Inorganic Violet Pigment Based on Zn₃Mo₂O₉

Colorants
(Zn1−xCox)3Mo2O9 (0 ≤ x ≤ 0.15) samples were synthesized as novel inorganic violet pigments by a conventional solid-state reaction method, and the obtained powders were characterized by X-ray powder diffraction (XRD), field-emission scanning electron ...

Bio‐Inspired Synthesis of Macroporous Single Crystal Particles as Scattering Agents

Advanced Functional Materials, EarlyView.
A general strategy is presented that delivers unique, single‐crystal microparticles that combine submicron macroporosity and uniform particle shapes. A bioinspired approach is used to occlude three distinct types of additives – polystyrene microspheres, polymer vesicles and amino acids – within calcite single crystals, and subsequent thermal annealing ...

New Water Oxidation Mechanism in Photosystem II Resolves Major Experimental Controversies

Angewandte Chemie, EarlyView.
In Photosystem II Oxygen Evolving Complex, we discovered the O3‐O6 peroxide at lower energy. Assignment of the O3 ligated by histidine (His337) as a slow exchanging substrate and its coupling with O6 give the O─O bond formation mechanism most consistent with all currently available experimental data. Proposal shows how protein environment can steer the

Precise in-situ detection of inorganic pigments in ancient architectural color paintings by HH-XRF

Heritage Science, 2023
The handheld X-ray fluorescence spectrometer (HH-XRF) is commonly used to detect the inorganic elemental composition of pigments on-site. However, the accuracy of in-situ detection results can be affected by the characteristics of the painted surface ...

Supramolecular Modulation of Photoinduced Charge Transfer: Tuning Between Tunneling and Incoherent Hopping

Angewandte Chemie, EarlyView.
Molecular recognition guest binding can comprehensively modulate photoinduced charge‐transfer dynamics in the cyclophane host, including charge separation and recombination, via coherent superexchange and incoherent hopping. Unlike covalent donor–bridge–acceptor systems, this supramolecular approach avoids tedious syntheses and offers precise tuning of
