Multi‐Biomimetic Structural Colors Inspired by Pearls and Bird Feathers

Advanced Materials, EarlyView.
A dual‐biomimetic strategy mimicking pearls and bird feathers is proposed to construct full‐gamut structural colors. By integrating a non‐strictly periodic inorganic multilayer architecture with tunable light absorbers, this facile approach circumvents the complex fabrication of traditional 1D photonic crystals, offering immense potential for cosmetics,

Inverse Design of Nanoparticulate Materials

Advanced Materials, EarlyView.
Inverse design shifts nanomaterial development from empirical trial‐and‐error to predictive model‐driven strategies. It can rely on knowledge‐based, data‐based, or hybrid process and property functions. This perspective article provides a practical framework for applying inverse design based on instructive examples. It discusses which modeling approach

Pigment compositions in Siberian early Upper Paleolithic complexes

UISPP Journal, 2021
Cultural assemblages associated with archaic forms of Homo sapiens in Siberia appeared around 40 000 – 50 000 years BP, revealing the evidence of the modern behavioural complex and use of various pigments.

Fabrication of Aligned Polycaprolactone Nanofibrillar Bundles to Control Cell‐Mediated Collagen Deposition in Engineered Cartilage

Advanced Materials, EarlyView.
Melt electrofibrillation (MEF) enables the fabrication of nanofibrillar PCL scaffolds with defined architectures that guide cellular alignment and retention during cartilage tissue engineering. Unlike conventional melt electrowriting, MEF consistently directs collagen type II‐rich extracellular matrix organization, providing a tunable platform to ...

A review on betacyanins and anthocyanins as water‑soluble pigments in nanotechnology‑based natural cosmeceutical formulations

Life Sciences, Medicine and Biomedicine
Many cosmetic products, such as lipsticks, often use synthetic dyes that have raised safety concerns. As a result, natural pigments with antioxidant properties are preferred in cosmeceutical formulations as safer alternatives.

3D Printed Photon Shield Assembly for Low‐Noise Visual Stimulation During Two‐Photon Imaging in Mice

Advanced Materials Technologies, EarlyView.
We present the Photon Shield, an open‐hardware system for low‐noise two‐photon calcium imaging during visual stimulation in mice. Combining a 3D‐printed headplate and rail‐mounted shield substantially reduces stray‐light contamination, as quantitatively verified. Functional validation confirms reliable cortical responses. Open design files enable broad

An AI‐Enabled All‐In‐One Visual, Proximity, and Tactile Perception Multimodal Sensor

Advanced Robotics Research, EarlyView.
Targeting integrated multimodal perception of robots, an AI‐enabled all‐in‐one multimodal sensor is proposed. This sensor is capable of perceiving three types of modalities, including vision, proximity, and tactility. By toggling an ultraviolet light and adjusting the camera focus, it switches smoothly between multiple perceptual modalities, enabling ...

A Pentaradial and Bilateral Combined Photoreception System in the Sea Cucumber is Mediated by a Blue Light‐Sensitive R‐Opsin

Advanced Science, EarlyView.
The sea cucumber Holothuria leucospilota detects blue and adjacent wavelengths of light via an r‐opsin with a maximum absorption at 459 nm. In the oral tentacles, papillae, and tube feet, distinct light‐sensing structures with specialized morphologies are formed, constituting a unique pentaradial and bilateral combined photoreception system.
