Crystallographic phase stability of nanocrystalline polymorphs TiO2 by tailoring hydrolysis pH

open access: yesSouth African Journal of Chemical Engineering
Nanocrystal TiO2 of high crystallinity (88.72 %) polymorphs have been synthesized by a unique simple route. At a low temperature under a measurable condition with differentiated hydrolysis pH of the reaction.

Enhancing the Production of the Fungal Pigment Aurofusarin in Fusarium graminearum

open access: yesToxins, 2018
There is an increasing demand for products from natural sources, which includes a growing market for naturally-produced colorants. Filamentous fungi produce a vast number of chemically diverse pigments and are therefore explored as an easily accessible ...

Light‐Harvesting Nanomaterials Based on Dyes for Energy Transfer and Amplified Biosensing

open access: yesAdvanced Materials, EarlyView.
Light harvesting (LH) in plants inspires researchers to develop artificial LH nanomaterials. Here, LH nanomaterials based on organic dyes are reviewed, considering fundamental challenges on aggregation‐caused quenching, excitation energy transfer, and exciton migration length.

Pigments of Lepidoptera [PDF]

open access: yesNature, 1892
I WAS about to pen some remarks on Mr. Perry Coste's recent articles on this subject, when a letter from Mr. Gowland Hopkins in the last number of NATURE (p. 581) expressed substantially the same views as those which I had arrived at. I write now rather to support Mr. Hopkins in his strictures than to offer any fresh criticisms of my own.

Harnessing Photo‐Energy Conversion in Nanomaterials for Precision Theranostics

open access: yesAdvanced Materials, EarlyView.
Harnessing photo‐energy conversion in nanomaterials enables precision theranostics through light‐driven mechanisms such as photoluminescence, photothermal, photoelectric, photoacoustic, photo‐triggered surface‐enhanced Raman scattering (SERS), and photodynamic processes. This review explores six fundamental principles of photo‐energy conversion, recent

A plasticidade dos amorfos: fazendo pigmentos brancos com fosfato de alumínio The plasticity of non-crystalline solids: aluminum phosphate white pigments

open access: yesQuímica Nova, 2007
A new white pigment made out of nano-structured non-crystalline aluminum phosphate was recently launched as an industrial product. Pigment opacifying properties are not intrinsic to aluminum phosphate but they arise as the result of a rare hollow ...
