Current Collector Engineering for New Efficient Bioresorbable Sodium‐Ion Batteries

open access: yesAdvanced Science, EarlyView.
A bioresorbable Na‐ion battery is proposed with Mo or Mg thin‐film current collectors for temporary implants. Mo‐based batteries exhibit superior electrochemical performance and stable cycling compared with Mg counterparts. XPS was used to investigate the Mo/Mg surface oxidation.

Perceptions of carotenoid and melanin colouration in faces among young Australian adults [PDF]

open access: yes, 2018
Objective:  Human skin colour is influenced by three pigments: haemoglobin, carotenoids, and melanin. Carotenoids are abundant in fruits and vegetables, and when consumed accumulate in all layers of the skin, predominantly imparting yellowness (b*). This

Remapping the Synthetic Landscape of α‐Tertiary Alkylamines via Dual‐Functional Catechol

open access: yesAngewandte Chemie, EarlyView.
A three‐component assembly strategy has been developed for the modular synthesis of hindered α‐tertiary aliphatic amines from readily available precursors through unlocking the dual role of catechol. The practicality of this methodology has been demonstrated in over 90 examples, including compounds that are otherwise difficult to access, along with ...

Inhalable ROS‐Responsive Nanospray Activates PPAR‐γ to Restore Macrophage Mitochondrial Homeostasis and Attenuate Radiation‐Induced Lung Injury

open access: yesAdvanced Science, EarlyView.
A nebulized nanoassembly alleviates radiation‐induced lung injury by reprogramming macrophages through coordinated ROS scavenging, NAD+ replenishment, and PPAR‐γ activation. Redox balance, mitochondrial homeostasis, and immune regulation are restored, revealing a microenvironment‐centered strategy for localized radioprotection.

A Disulfide‐Sticker Strategy for Marine Adhesive Coatings: From Deciphering Self‐Assembly Mechanism to Functional Application in Hair Regeneration

open access: yesAdvanced Science, EarlyView.
A disulfide‐sticker strategy, coupled with Ca2+ coordination, drives the hierarchical self‐assembly of a recombinant scallop adhesive protein into fishnet‐like nanostructures, affording a coating with versatile wet adhesion and intrinsic antioxidant activity. This biocompatible coating markedly promotes hair regeneration by activating follicular niches,

Cuttlefish Ink Melanin Encapsulated in Nanolipid Bubbles and Applied Through a Micro-Needling Procedure Easily Stains White Hair Facilitating Photoepilation [PDF]

open access: yes, 2016
[EN] Background: Photothermolysis of unwanted hair depends on the presence of melanin in the hair follicle as the chromophore, but is not effective in patients with non-pigmented, melanin-sparse hair shafts and follicles.

Melanin distribution from the dermal–epidermal junction to the stratum corneum: non-invasive in vivo assessment by fluorescence and Raman microspectroscopy

open access: yesScientific Reports, 2020
The fate of melanin in the epidermis is of great interest due to its involvement in numerous physiological and pathological processes in the skin. Melanin localization can be assessed ex vivo and in vivo using its distinctive optical properties.
