Cool and photocatalytic yellow ceramic pigments; from lead-tin to Cr doped scheelite pigments
Ceramics International, 2019Abstract The historical lead based pigments (XVII-XVIII century), the modern Ni,Sb-rutile (1939) and Pr-zircon (1961) yellow pigments as well as the novel yellow pigments based on Cr-scheelite and Mo-yttrium cerate pigments were synthesized and compared as semiconductors of high NIR reflectance (cool pigments) and with photocatalytic activity.

Nano-Titania Decorated Fly Ash as Self-Cleaning Antibacterial Cool Pigment
ACS Sustainable Chemistry & Engineering, 2015Fly ash (FA) is an industrial waste produced in large quantities whereas nano-TiO2 is a widely studied material for multifarious applications. Synergy of the two materials is created to produce a multifunctional composite material for low cost NIR reflective coating applications. Effective formation of a TiO2 shell on the FA core was achieved by use of

Low-temperature synthesis of environment-friendly cool yellow pigment: Ce substituted SrMoO4
Materials Letters, 2020Abstract A new sequence of novel yellow pigments Sr1-xCexMoO4 (x = 0, 0.1, 0.2, 0.3, 0.4, 0.5) was prepared by following low temperature hydrothermal method. The bandgap of the materials was decreased from 3.95 eV to 3.48 eV with an increase in the Ce3+ substitution. SrMoO4 rhomboids have turned into spherical balls as the Ce3+ substitution increased.

Highly Reflective Nanostructured Titania Shell: A Sustainable Pigment for Cool Coatings
ACS Sustainable Chemistry & Engineering, 2017Core–shell materials are designed to bring synergy of two materials. We describe a greener approach for fabrication of fly ash (FA)-based cool pigment having core–shell morphology, viz., FA as core and multilayers of nano-TiO2 as shell—introducing high reflectivity in the near infrared region.

Preparation of (Fe,Cr)2O3@TiO2 cool pigments for energy saving applications
Journal of Alloys and Compounds, 2019Abstract The use of cool pigments is considered to be a proper strategy to reduce energy consumption in buildings. In the present research, cool pigment nanocomposites based on Fe, Cr and Ti oxides were synthesized as two different composites namely (Fe,Cr)2O3@TiO2 core-shell and physically mixed oxides ones.

Pigment Changes in Cool‐Season Turfgrasses in Response to Ultraviolet‐B Light Irradiance
Agronomy Journal, 2015Pigments and phenolics that absorb ultraviolet light (UV) are involved in the protection of the photosynthetic apparatus during periods of high ultraviolet‐B (UV‐B) radiation and can be of benefit to turfgrasses. This study initiated in October 2010 and repeated in March 2011 aimed to characterize protective pigment responses to elevated UV‐B in cool ...
