Bio‐Inspired Magnetically Tunable Structural Colors from Elliptical Self‐Assembled Block Copolymer Microparticles

open access: yesAdvanced Functional Materials, EarlyView.
Cephalopod‐inspired photonic microparticles with dynamic structural coloration are fabricated via confined self‐assembly of linear block copolymers into ellipsoids containing stacked lamellae. Embedded superparamagnetic nanoparticles enable rapid magnetic alignment, restoring vivid, angle‐dependent color.

Thermal comfort in the historical urban canyon: the effect of innovative materials [PDF]

open access: yes, 2017
Urban heat island (UHI) can considerably affect the thermal quality of the urban environment, especially within urban canyons, that have typically low sky view factor and limited surface heat re-emission capability.

Structure Formation in Butterfly Scales: Interplay of Genetic Control, Mechanical Instabilities, and Dynamic Material Properties

open access: yesAdvanced Functional Materials, EarlyView.
Butterfly wing scales are intricate cuticular functional nanosctructures. This perspective suggests that spatially varying material properties, cytoskeletal constraints, and growth‐driven mechanical instabilities shape the resulting nanoscale architectures created from single cells.

The First Opsins Prediction in Achatina fulica Genome

open access: yesBiology and Life Sciences Forum, 2022
The variety of spectral properties of visual pigments is provided mainly by the amino acid sequences of their protein component, the so-called visual opsins.

Metachromatic Butterfly Bile Pigments for Multi‐Level Optical Security Films

open access: yesAdvanced Functional Materials, EarlyView.
Bio‐derived optical security materials are manufactured by embedding butterfly‐based pigments in polymer films. Tunable color and fluorescence responses arise from concentration‐controlled metachromasy, enabling spatially encoded patterns with distinct visible, UV‐active, and spectral signatures.

CHANGES IN VISUAL APPEARANCE OF RED AND GREEN UV-VISIBLE FLUORESCENT PRINTS AS A CONSEQUENCE OF THE ACCELERATED AGEING

open access: yesJournal of Industrial Design and Engineering Graphics, 2022
Pigments with special effects are nowadays utilized in the graphic engineering and design to achieve an added value of the final product. Daylight-invisible, UV-visible fluorescent pigments can be used as markings, sensors, as well as special design or ...

The evolution of opsins and color vision: connecting genotype to a complex phenotype

open access: yesActa Biológica Colombiana, 2016
Dissecting the genetic basis of adaptive traits is key to our understanding of evolutionary processes. A major and essential step in the study of evolutionary genetics is drawing link between genotype and phenotype, which depends on the difficult process

Visual adaptation of opsin genes to the aquatic environment in sea snakes

open access: yesBMC Evolutionary Biology, 2020
Background Evolutionary transitions from terrestrial to aquatic life history cause drastic changes in sensory systems. Indeed, the drastic changes in vision have been reported in many aquatic amniotes, convergently.

Effects of reduced dissolved oxygen concentrations on physiology and fluorescence of hermatypic corals and benthic algae. [PDF]

open access: yes, 2014
While shifts from coral to seaweed dominance have become increasingly common on coral reefs and factors triggering these shifts successively identified, the primary mechanisms involved in coral-algae interactions remain unclear. Amongst various potential
