The unusual microtubule polarity in teleost retinal pigment epithelial cells. [PDF]

open access: yes, 1988
In cells of the teleost retinal pigment epithelium (RPE), melanin granules disperse into the RPE cells long apical projections in response to light onset, and aggregate toward the base of the RPE cell in response to dark onset.

Intramural pure pigment gall­stones, a case report [PDF]

open access: yes, 1963
A case of intramural pure pigment gallstones, which were fortuitously found in post-mortem examination, is presented. The incidence, mechanism of formation of the stones and roentgenological diagnosis of the intramural gallstones, porcelain gall bladder,

Pigment Cells and Pigment Cell Tumors in Fish

open access: yesJournal 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 ...

Adjustment of Coatings Morphology and Particle Distribution of Layered Silicates by Freeze‐Drying for Improved Gas Barriers

open access: yesAdvanced Engineering Materials, EarlyView.
Freeze‐drying of layered silicate is the key to get coatings with superior gas barrier. Freeze‐drying of layered silicates modified with dodecylamine (DDA) is a highly effective technique for the preparation of barrier pigments that significantly mitigate the permeation of oxygen, water vapor, and hydrogen through polymer films containing these ...

High‐Performance Low‐Emissivity Paints Enabled by N‐Doped Poly(benzodifurandione) (n‐PBDF) for Energy‐Efficient Buildings

open access: yesAdvanced Functional Materials, EarlyView.
This study introduces a scalable and colored low‐emissivity (low‐e) paint achieved by spraying an ultrathin n‐doped poly(benzodifurandione) (n‐PBDF) coating onto various colored substrates. The low‐e paint enhances thermal regulation by reducing mid‐infrared thermal emissivity to 0.19, thereby stabilizing indoor temperatures across diverse climates ...

Enhancing Optoelectronic Properties in Phthalocyanine‐Based SURMOFs: Synthesis of ABAB Linkers by Avoiding Statistical Condensation with Tailored Building Blocks

open access: yesAdvanced Functional Materials, EarlyView.
A novel phthalocyanine (PC)‐based metal–organic framework (MOFs) is synthesized using ditopic PC linkers obtained through regioselective statistical condensation. The resulting MOF exhibits significant improvements in electronic absorption, thereby enhancing the material's performance in light harvesting and energy conversion.
