3D Anodic Alumina Nanoarchitectures: A Decade of Progress from Foundational Science to Functional Metamaterials

Advanced Materials, EarlyView.
Ordered three‐dimensional anodic aluminum oxide (3D‐AAO) nanoarchitectures with longitudinal and transverse pores enable architecture‐driven metamaterials. The review maps fabrication advances, including hybrid pulse anodization, and shows how 3D‐AAO templates tailor properties across magnetism, energy, catalysis, and sensing.

Síntese de pigmentos cerâmicos por precipitação química Synthesis of ceramic pigments by chemical precipitation

Cerâmica, 2007
Os pigmentos cerâmicos são substâncias capazes de desenvolver cor em sólido inorgânico (cerâmica ou vidro) quando nele dispersar mantendo-se insolúvel no mesmo, sem reação química com o mesmo, nas elevadas temperaturas de processamento.

Leaftronics: Bio‐Fractal Scaffolds From Leaf Venation for Low‐Waste Electronics

Advanced Materials, EarlyView.
“Leaftronics” transforms naturally evolved leaf venation into quasi‐fractal scaffolds for sustainable electronics. Polymer‐infiltrated leaf skeletons can be used to fabricate ultra‐smooth, reflow‐ and thin‐film‐compatible decomposable substrates, while making the same lignocellulose networks conducting results in flexible transparent electrodes.

Pigment Cells and Pigment Cell Tumors in Fish

Journal of Investigative Dermatology, 1989
The three basic pigment cell types found in poikilothermic vertebrates, melanocytes (melanin-producing cells), erythrophores (red or yellow pigment cells), and iridophores (iridescence-producing cells), are derived from neural crest. Neoplasms of pigment cells in fish are also of three phenotypes, melanomas (melanophoromas), erythrophoromas, and ...

Bile bilirubin pigment analysis in disorders of bilirubin metabolism in early infancy

, 2001
BACKGROUNDEarly and accurate diagnosis of Crigler-Najjar syndrome, which causes prolonged unconjugated hyperbilirubinaemia in infancy, is important, as orthotopic liver transplantation is the definitive treatment.

Surface‐Ligand‐Dependent Excited‐State Dynamics in Aqueous CuInSe2/ZnS Quantum Dot–Chlorophyll Assemblies

Advanced Materials Interfaces, EarlyView.
CuInSe2/ZnS quantum dots are synthesized in water and coupled with chlorophyll to probe ligand‐controlled excited‐state interactions. Broad visible–NIR emission and high PLQY are observed. Time‐resolved measurements reveal shortened chlorophyll lifetimes, indicating dynamic quenching via Förster energy and/or charge transfer, highlighting surface ...

Serum zinc level in vitiligo: A case-control study

Indian Journal of Dermatology, 2018
Background: Vitiligo is characterized by the idiopathic destruction of melanocytes, probably of autoimmune etiology, that results in depigmented patches of skin and mucosal surfaces. Oxidative stress may contribute to the pathogenesis of vitiligo.

Studies of pigment transfer between Xenopus laevis melanophores and fibroblasts in vitro and in vivo

, 2006
Frog melanophores rapidly change colour by dispersion or aggregation of melanosomes. A long-term colour change exists where melanosomes are released from melanophores and transferred to surrounding skin cells.
