Comparison of different X‐ray‐based scanning electron microscopy methods to detect sub‐nanometre ultra‐thin InAs layers deposited on top of GaAs

Journal of Microscopy, EarlyView.
Abstract We compare three different methods of X‐ray analysis in a scanning electron microscope (SEM): energy‐dispersive X‐ray spectroscopy (EDX), wavelength‐dispersive X‐ray spectroscopy (WDX) and micro X‐ray fluorescence (μXRF). These methods are all applied to the same gallium arsenide (GaAs) wafer with a 0.8 nm layer of indium arsenide (InAs) on ...

Highly Efficient Sky‐Blue Perovskite Quantum Dot Light‐Emitting Diodes via Ligand‐Assisted Trap‐State Passivation

ENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 4, July 2026.
Highly efficient sky‐blue LED with EQE of 13.6% is realized through short‐chain ligand tridecylamine treaded perovskite quantum dots, due to the suppressed non‐radiative recombination from the trap state. These results indicate that the ligand with strong affinity can facilitate the surface defects passivation, resulting in enhanced optical properties,

Constructing Cu/Cu2O Heterogeneous Interface for Efficient Urea Electrosynthesis

ENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 4, July 2026.
In this study, a Cu/Cu2O heterogeneous interface with dual active sites is prepared for electrocatalytic CO2 and NO3− coupling to urea. The catalyst shows high yield rates of 1156.63 mmol g−1 h−1 and FE of 29.67% at −1.0 V (vs RHE), which is significantly higher than Cu and Cu2O, highlighting the advantages of heterogeneous interface synergistic ...

Radiolabeled Angiopep‐2 Peptide Vector as a Preclinical Platform for Blood–Brain Barrier Targeting: Synthesis, Radiolabeling, and Preliminary In Vivo Biodistribution in Mice

Journal of Peptide Science, Volume 32, Issue 7, July 2026.
The developed DOTA‐Angiopep‐2 conjugate was well tolerated in glioma cells and enabled high‐yield radiolabeling with 177Lu and 161Tb. The 161Tb conjugate showed brain delivery with predominantly renal clearance, supporting a stable radiotheranostic platform for BBB‐targeted glioma therapy and SPECT imaging.

3d-resonant photo- and Auger emission of Ce in CeO2

, 1995
The Ce 3d-edge resonant photoelectron and Auger electron emission spectra in CeO2 have been measured. The 4s-, 4p- and 4d-emission at off-resonance excitations consists of two parts separated by about 13 eV, which correspond to different final-state ...

Quantitative Model of Internal Analyzer Scattering in a Hemispherical Electron Analyzer and Its Application to Improve the Accuracy of the Transmission Function

Surface and Interface Analysis, Volume 58, Issue 7, Page 456-470, July 2026.
ABSTRACT Internal scattering within hemispherical electron analyzers (HEA) is common when operating at low pass energies, where the instrument resolution of X‐ray photoelectron spectroscopy (XPS) and Auger electron spectroscopy experiments are at their best.

Thermal and Photocatalytic Conversion of CO2 to Ethanol: Advances in Catalyst Design, Challenges, and Opportunities

ChemSusChem, Volume 19, Issue 12, 26 June 2026.
This review examines thermo‐ and photocatalytic routes for converting CO2 to ethanol and analyzes how metal alloying, promoters, supports, surface structure, and semiconductor design govern catalyst activity, selectivity, and stability. It integrates mechanistic insights from experimental and theoretical studies and identifies the main challenges and ...
