Bioinspired, Mitochondria‐Targeted Single‐Atom Nanozyme Enhances Bone Regeneration by Reprogramming Stem Cell Energy Metabolism​

open access: yesAdvanced Materials, EarlyView.
A bioinspired nanozyme—triphenylphosphonium (TPP)‐dendritic mesoporous silica nanoparticle (DMSN)‐Fe/Cu—mimics mitochondrial complex IV and targets mitochondria to regulate cellular energy metabolism. This approach markedly boosts bone regeneration in vivo, as demonstrated by enhanced bone volume and mineral density in critical‐sized bone defects rat ...

Characterization of peroxidase and catalase genes in defense mechanisms of Physcomitrella patens [PDF]

open access: yes, 2019
Systemic acquired resistance (SAR) and the hypersensitive response (HR) are two important induced defense mechanisms in plants. SAR is the development of an enhanced resistance to a pathogen due to a prior encounter.

Two‐Dimensional Reconfigurable Photodiode for In‐Sensor Color Filtering and Spectral Logic

open access: yesAdvanced Materials, EarlyView.
By harnessing the photodoping of different aggregates, the device exhibits wavelength‐dependent volatile‐to‐nonvolatile photoresponses that can be reconfigured via bias modulation. This enables in‐sensor color filtering and spectral‐encrypted information processing, eliminating reliance on external optical filters or post‐processing algorithms ...

Entropy‐Driven Spin Transition in Rare Earth Perovskites Enables Feedback Adsorption for Enhanced Acidic Water Oxidation

open access: yesAdvanced Materials, EarlyView.
A synthetic protocol for fabricating high‐entropy rare earth perovskite oxides with abundant lattice distortions and oxygen vacancies has been developed, representing an emerging platform for anchoring RuO2. High entropy strategy significantly modulated the electronic structures and spin states, inducing a shift in the mechanism from the adsorption ...

Boosting Seawater Desalination by Ampere‐Level Nitrate Electroreduction On Defect‐Rich Ultrathin RuCu Alloy Nanostructures

open access: yesAdvanced Materials, EarlyView.
Defect engineering of ultrathin RuCu alloy nanostructures has been successfully achieved to enhance ammonia electrosynthesis under indutrial‐level current density. Simultaneously, the stable ampere‐level operation of nitrate electroreduction on defective RuCu nanostructures can drive seawater desalination at an ultrafast salt removal rate, offering an ...
