High‐Entropy Liquid Metal Process for Transparent Ultrathin p‐Type Gallium Oxide

Advanced Functional Materials, EarlyView.
This work introduces a doping strategy for harvesting ultrathin Ga oxide layers using a multi‐elemental Ga‐based liquid metal alloy. The incorporation of trivalent In metal into the self‐limiting oxide formed on the alloy's surface is enabled by the existence of atomically dispersed Pt, Au, and Pd.

f‐p‐d Gradient Orbital Coupling Induced Spin State Enhancement of Atomic Fe Sites for Efficient and Stable Oxygen Reduction Reaction

Advanced Functional Materials, EarlyView.
The f‐p‐d (Eu─O─Fe) gradient orbital coupling induces electron delocalization and the introduced f‐band of Eu shifts the spin state of the Fe center in FePc from low‐spin to intermediate‐spin. This strategy simultaneously enhances oxygen reduction reaction (ORR) activity, reaction kinetics, and stability, resulting in superior ORR performance and ...

Understanding and Optimizing Li Substitution in P2‐Type Sodium Layered Oxides for Sodium‐Ion Batteries

Advanced Functional Materials, EarlyView.
This work explores Li‐substituted P2 layered oxides for Na‐ion batteries by crystallographic and electrochemical studies. The effect of lithium on superstructure orderings, on phase transitions during synthesis and electrochemical cycling and on the interplay of O‐ versus TM‐redox is revealed via various advanced techniques, including semi‐simultaneous

Sono‐Piezo‐Photosynthesis of Ethylene and Acetylene from Bioethanol under Ambient Conditions

Advanced Functional Materials, EarlyView.
A novel sono‐piezo‐photocatalytic strategy enables the conversion of bioethanol to ethylene (C2H4) and acetylene (C2H2) under ambient conditions, addressing the limitations of conventional methods that are high‐temperature and energy‐intensive. By using an advanced graphene oxide/sodium bismuth titanate heterostructure catalyst, this work achieved ...

H2O2‐Generating Advanced Nanomaterials for Cancer Treatment

Advanced Functional Materials, EarlyView.
H2O2‐generating nanoplatforms can exploit tumor redox imbalance for O2 and toxic reactive oxygen species generation, leading to hypoxia reversal, and apoptosis of cancer cells, respectively. This review highlights the mechanisms of these nanoplatforms, including exogenous H₂O₂ delivery, endogenous amplification, and metal peroxides, which leads to ...

Alleviation of Aging‐Related Hallmarks in a Mouse Model of Progeria via a Nanoparticle‐Based Artificial Transcription Factor

Advanced Functional Materials, EarlyView.
Oct4‐nanoscript, a biomimetic nanoparticle‐based artificial transcription factor, precisely regulates cellular rejuvenation by activating Oct4 target genes, restoring epigenetic marks, and reducing DNA damage. In a progeria model, it effectively rescued aging‐associated pathologies and extended lifespan.

Using Recycled Materials in a Novel Dual Binder System for Hard Carbon Anodes: Closing the Loop Toward Sustainable Li‐/Na‐ion Batteries

Advanced Functional Materials, EarlyView.
The study explores for the first time the use of polyvinyl butyral (PVB), particularly recycled PVB, as a sustainable binder for Li/Na‐based electrodes in the framework of the H2020 SUNRISE EU project. Findings revealed that electrodes bound with a sustainable PAA/PVB mixture demonstrated exceptional rate capability and high initial Coulombic ...

Particle Accelerators and Particle Detection [PDF]

, 2011
The possibility of investigating the subatomic world is related to the con- struction of increasing larger and more sophisticated accelerators. Here, the energy available in a collision is converted into mass (= new exotic particles) according to the Einstein equation E=mc 2.

Particle Acceleration in Mercury’s Magnetosphere [PDF]

Space Science Reviews, 2007
This paper is devoted to the problem of particle acceleration in the closest to the Sun Hermean magnetosphere. We discuss few available observations of energetic particles in Mercury environment made by Mariner-10 in 1974-1975 during Mercury flyby's and by Helios in 1979 upstream of the Hermean bow shock.
