Extrinsic and Intrinsic Charge Transfer at Interfaces of Membrane‐Based Oxide Heterostructures

open access: yesAdvanced Electronic Materials, EarlyView.
Freestanding oxides have emerged as a new opportunity to tailor oxides outside of the typical epitaxial constraints. We present the fabrication of TiO2‐terminated SrTiO3 membranes via direct growth control. We demonstrate competing ionic and electronic charge transfer in LaAlO3/SrTiO3 bilayers using near ambient pressure XPS.

A method for detecting two‐dimensional plane stress distribution in basin‐type insulator based on critically refracted longitudinal wave

open access: yesHigh Voltage
Basin‐type insulator often has small cracks due to stress concentration. The current method cannot accurately reflect the stress condition of the insulator to find the stress concentration areas.

High-power testing of 1100 and 1200 kV circuit breakers

open access: yes, 2009
Circuit breakers for UHV (Ultra High Voltage, rated voltage ?? 800 kV) are required especially for various large-scale transmission projects, China (1100 kV) being the most recent focal point but India to follow soon with 1200 kV.

Advancing Energy Materials by In Situ Atomic Scale Methods

open access: yesAdvanced Energy Materials, Volume 15, Issue 11, March 18, 2025.
Progress in in situ atomic scale methods leads to an improved understanding of new and advanced energy materials, where a local understanding of complex, inhomogeneous systems or interfaces down to the atomic scale and quantum level is required. Topics from photovoltaics, dissipation losses, phase transitions, and chemical energy conversion are ...

Study on the Impact of UHV AC Composite Cross-arms on Live Working Safety

open access: yesZhongguo dianli, 2019
The UHV AC composite cross-arm structure, quite different from the conventional towers, has a significant impact on the safety distance of live working, the mode of entering or exiting equipotential, and the electric field protection requirements of ...

Zur Rolle von Wasser bei der CO2‐Reduktion an defektreichem TiO2 bei niedrigen Temperaturen

open access: yesAngewandte Chemie, EarlyView.
Unsere Ergebnisse unterstreichen das Potenzial von reduziertem Titandioxid als edelmetallfreiem Katalysator zur Aktivierung von CO2 und zeigen in situ die Reaktion von CO2 auf defektreichem TiO2 unter Verwendung von synchrotronbasiertem NAP‐XPS von Raumtemperatur bis 700 K.

From Sparse Nanoparticles to Graded Interfaces: Beyond Classical Descriptions of LiF Growth on Organic Semiconductors. [PDF]

open access: yesChem Asian J
LiF grows on diindenoperylene not as a smooth film but as sparse, inhomogeniety associated nanoparticles that evolve stochastically toward full coverage, perturbing the interface while leaving the organic lattice intact. ABSTRACT Small‐molecule π$\pi$‐conjugated semiconductors provide an ordered platform for probing interfacial mechanisms in organic ...

Growth of SiGe by D-UHV/CVD at Low Temperature

open access: yes, 2008
The temperature is a key factor for the quality of the SiGe alloy grown by D-UHV/CVD. In conventional conditions,the lowest temperature for SiGe growth is about 550℃.

Role of Water in Low‐Temperature CO2 Reduction at Defect‐Rich TiO2

open access: yesAngewandte Chemie International Edition, EarlyView.
Our results highlight the potential of reduced titania as a noble metal‐free CO2 activation catalyst and show the activation of CO2 on highly defective TiO2 using in situ synchrotron‐based NAP‐XPS from room temperature to 700 K. The distribution of surface intermediates can be decoded as a simultaneous population of reaction routes, revealing water (OH)
