Tuning the Surface State and Zeta Potential of Aged CuO Nanoparticles by Additive‐Free Surface Treatments as Guided by XPS

Advanced Materials, EarlyView.
Aging of CuO nanoparticles (NP) involves a surface reconstruction induced by hydroxylation and concurrent organic‐O adsorption, which introduces O defects in the NP subsurface region. The defective surface results in a diffuse surface space region, as reflected by a low ζ‐potential of the aged NPs in ethanol solvent.

Nanoconfined Cu─O─Mo Asymmetric Sites Enable Ambient Spontaneous O2‐to‐1O2 Conversion for Sustainable Water Purification

Advanced Materials, EarlyView.
An asymmetric Cu+─O─Mo6+ dual‐site in a nanoconfined membrane turns O2 into singlet oxygen at ambient conditions with ≈95% selectivity, bypassing superoxide. It concentrates reactants for rapid pollutant removal, operates stably in continuous flow with ultra‐low metal leaching and cost, efficiently purifying complex waters.

A Model to Realize the Potential of Auger Electrons for Radiotherapy

EPJ Web of Conferences, 2013
Auger-electron-emitting radioisotopes provide a unique tool that enables the targeted irradiation of a small volume in their immediate vicinity. Over the last forty years, Auger emission has been established as a promising form of molecular radiotherapy,

2D Indium Oxide at the Epitaxial Graphene/SIC Interface: Synthesis, Structure, Properties, and Devices

Advanced Materials, EarlyView.
A new monolayer insulator, InO2, is synthesized by intercalating indium beneath patterned epitaxial graphene on SiC, followed by high‐temperature oxidation. This selective confinement yields large‐area, uniform InO2 with a wide bandgap of 4.1 eV. Upon intercalation, the EG/n‐SiC junction transitions from ohmic to Schottky, exhibiting a rectification ...

Ultrathin Monatomic Antimony Films by Sacrificial Atomic Layer Deposition for Phase Change Memory

Advanced Materials, EarlyView.
A three‐step sacrificial atomic layer deposition (s‐ALD) process enables wafer‐scale growth of ultrathin and uniform antimony (Sb) thin films. An ultrathin (≈4 nm) Sb film is uniformly deposited with its characteristic bilayer structure (Sb‐Sb) aligned along the substrate.

Disentangling Auger decays in O2 by photoelectron-ion coincidences

Scientific Reports, 2017
In non-resonant Auger electron spectroscopies, multi core-ionized states lead to numerous energetically close-lying electronic transitions in Auger spectra, this hampering the assignment and interpretation of the experimental results.

Understanding the Dynamics of Nanoparticle Formation and Evolution in Functional Oxides via In Situ SAXS/WAXS

Advanced Materials Interfaces, EarlyView.
In situ SAXS/WAXS enables real‐time tracking of nanoparticle formation and evolution in exsolved and infiltrated Ni‐based perovskites under reducing conditions. The combined technique captures nucleation, growth, and coarsening dynamics with high temporal resolution, providing statistically robust insights into structural and morphological ...

Direct Ink Writing 3D Printing of Recyclable and Thermally Stable Vitrimers

Advanced Materials Technologies, EarlyView.
Vitrimers hold great promise in additive manufacturing as defect‐insensitive, repairable, and recyclable feedstocks. A thin‐film additively manufactured process is developed for a high‐performance vitrimer that is difficult to process traditionally.

Measurement of upward-going milli-charged particles at the Pierre Auger Observatory

Physics Letters B
It is assumed that superheavy dark matter particles with O(EeV) mass may decay to relativistic milli-charged particles (MCPs). The upward-going MCPs passing through the Earth can be measured by the fluorescence detectors (FD) of the Pierre Auger ...
