Bio‐Inspired Hierarchical Nanoreactor With Hetero‐Coordinated Fe–P–Co Bridges for Whole‐Pathway‐Regulated Electrocatalytic Oxygen Reduction

open access: yesAdvanced Materials, EarlyView.
A bioinspired Co‐doped Fe2P on N‐doped carbon with a hierarchical eucalyptus‐like nanoarchitecture is engineered to regulate oxygen across the entire electrochemical pathway, achieving a half‐wave potential of 0.938 V vs. RHE, sustaining 373 h of discharge in Al‐air batteries, and delivering an energy density of 3487 Wh/kg.

Impacts of Climate Change on Oceans and Ocean-Based Solutions: A Comprehensive Review from the Deep Learning Perspective

open access: yesRemote Sensing
Climate change poses significant threats to oceans, leading to ocean acidification, sea level rise, and sea ice loss and so on. At the same time, oceans play a crucial role in climate change mitigation and adaptation, offering solutions such as renewable

Membrane Semi‐Permeability and Ion Selectivity in Chemiosmosis: Open Systems Volume Dependence of Electrolyte Chemistry

open access: yesAdvanced Materials Interfaces, EarlyView.
Very small cellular compartments can break electroneutrality and harness proton gradients without active transport structures, whereas larger volumes cannot, underscoring why life's critical energy processes are confined in microscopic spaces. ABSTRACT The effect of pH changes in external ionic solutions on liposomes entrapping non‐permeable weak acid ...

Mechanically Tunable Mechanochromic Device with Covert‐Overt Structural Color and Modulation of its Transparency

open access: yesAdvanced Materials Interfaces, EarlyView.
This study presents a novel mechanically responsive optical device that modulates light transmission and generates iridescent structural colors under reflection. The optical transition arises from the exposure of nanoparticles upon stretching, which are initially embedded beneath the surface.

Dependence of Biological Activity on the Surface Water Fraction of Planets

open access: yes, 2019
One of the unique features associated with the Earth is that the fraction of its surface covered by land is comparable to that spanned by its oceans and other water bodies.

Expansion of Thaumarchaeota habitat range is correlated with horizontal transfer of ATPase operons. [PDF]

open access: yes, 2019
Thaumarchaeota are responsible for a significant fraction of ammonia oxidation in the oceans and in soils that range from alkaline to acidic. However, the adaptive mechanisms underpinning their habitat expansion remain poorly understood.

Development of Artificial Sebaceous Gland‐Integrated In Vitro Human Skin Model

open access: yesAdvanced Materials Interfaces, EarlyView.
Uniform 3D artificial sebaceous gland spheroids, termed SebaSpheres, are generated at high throughput using a microfluidic platform and structurally integrated into a collagen‐based skin construct containing fibroblasts and keratinocytes. This work presents a modular and scalable fabrication and integration strategy for incorporating sebaceous gland ...
