Handbook of Establishing and Maintaining Oxygen‐Free Atmospheres

Advanced Engineering Materials, Volume 28, Issue 12, 17 June 2026.
This study presents a practical framework for creating oxygen‐free atmospheres at ambient pressure using silane‐doped inert gases. The results show that ultra‐low oxygen levels and strongly reduced water content can be achieved through controlled silane dosing, drying systems, and sensor monitoring.

Abnormal steady-state overvoltage in transmission lines of UHV

, 2012
The reason of overvoltage at the abnormal conditions in transmission lines of UHV are researched. The source of parameters distortion which causes specific overvoltage under at the open-phase operating conditions of transmission lines is given.

Removing Oxide Layers and Retaining Oxide‐Free Steel Surfaces by Polishing in Oxygen‐Free Atmosphere

Advanced Engineering Materials, Volume 28, Issue 12, 17 June 2026.
In this study, the efficacy of wet mechanical polishing under an oxygen‐free atmosphere for deoxidation and the retention of an oxide‐free steel surface are elucidated using X‐ray photoelectron spectroscopy. The methodology proved successful; however, the results were highly dependent on the preparation of the solvents used to clean the samples after ...

Al–Cu Composite Casting of Laser‐Deoxidized Copper: Bonding, Interfacial Chemistry, and Thermal Conductivity

Advanced Engineering Materials, Volume 28, Issue 12, 17 June 2026.
This study investigates laser‐based oxide removal of Cu inserts in oxygen‐free conditions and examines long‐term oxidation kinetics and surface chemistry under different atmospheres via X‐ray photoelectron spectroscopy. Al–Cu compound casting with differently oxidized surfaces is performed, and intermetallic phase formation, morphology, and thermal ...

Nonthermal Plasma Reduction of Nickel Oxide Layers by Atmospheric Pressure Dielectric Barrier Discharge in Argon/Hydrogen

Advanced Engineering Materials, Volume 28, Issue 12, 17 June 2026.
This work explores the reduction of nickel oxide layers using dielectric barrier discharge plasma in an argon–hydrogen atmosphere. The results reveal a strong temperature dependence, enabling complete reduction of thick oxide layers at 200°C within seconds.

Dielectric Barrier Discharge Plasma Deoxidation of Natively Oxide Layer of Copper Powders in a Fluidized Bed

Advanced Engineering Materials, Volume 28, Issue 12, 17 June 2026.
This paper presents a novel approach to reducing oxide layers on metal powders using low‐temperature hydrogen dielectric barrier discharge plasmas at atmospheric pressure. Unlike conventional hydrogen‐plasma reductions, the powders do not contact the plasma directly.

Stabilisierung von interstitiellen Platin‐Atomen unterhalb der CeO2(111)‐ Oberfläche: Neue Ansätze für die Architektur von Einzelatom‐Katalysatoren

Angewandte Chemie, Volume 138, Issue 25, 15 June 2026.
Durch die Kombination polarisationsaufgelöster IRRAS an atomar flachen CeO2(111)‐Einkristallen mit quantitativen XPS‐ und DFT‐Berechnungen identifizieren wir eine ungewöhnliche interstitielle Konfiguration von Pt‐Einzelatomen in der Subsurface‐Region, die zu einer bisher unbeobachteten, blauverschobenen CO‐Schwingungsmode führt.

Subsurface Stabilization of Interstitial Pt Atoms on CeO2(111): Rethinking Single‐Atom Catalyst Architectures

Angewandte Chemie International Edition, Volume 65, Issue 25, 15 June 2026.
By combining polarization‐resolved IRRAS on atomically flat CeO2(111) single crystals with quantitative XPS and DFT calculations, we identify an unusual subsurface interstitial configuration of Pt single atoms that gives rise to a previously unobserved, blue‐shifted CO vibrational mode.
