Surface friction of rock in terrestrial and simulated lunar environments [PDF]

open access: yes
The conventional probe-on-the rotating-disk concept was used to determine the surface friction in mineral probe/specimen interfaces. Nine rocks or minerals and two stainless steels were tested in both new (NT) and same track (ST) tests under three ...

Native defects in ultra-high vacuum grown graphene islands on Cu(111)

open access: yes, 2015
We present a scanning tunneling microscopy (STM) study of native defects in graphene islands grown by ultra-high vacuum (UHV) decomposition of ethylene on Cu(111).

Spin‐Selective Interface Engineering in Oxide–Ferromagnetic Junctions via Atomic‐Scale Oxygen Control

open access: yesAdvanced Science, EarlyView.
We show that interfacial oxygen at the MgO/Fe interface can be transformed from an uncontrolled variable into a tunable design parameter for spintronic junctions. Momentum microscopy provides direct access to the momentum‐ and spin‐resolved electronic structure beneath the insulating MgO layers, revealing how oxygen intercalation reshapes buried Fe ...

The Temperature and Voltage Resistance Performance of Phenyl‐Modified Silicone Elastomers for High‐Voltage and High‐Power Semiconductor Device Encapsulation

open access: yesHigh Voltage
Silicon carbide (SiC) high‐voltage, high‐power semiconductor devices are essential for next‐generation power systems, yet conventional silicone elastomer encapsulation materials suffer from insulation degradation under extreme thermal and electrical ...

Non-characteristic Harmonic Analysis of Uhv ac/dc Systems

open access: yesMATEC Web of Conferences, 2019
Uhv direct current transmission has developed rapidly in China due to its unique advantages of large capacity, long distance and high voltage. A series of researches have been carried out on the non-characteristic harmonic current in the grid side of uhv

Study of CO Oxidation over Ru(0001) at High Gas Pressures

open access: yes, 1996
Experiments performed at high gas partial pressures have demonstrated that the kinetics of the CO oxidation reaction at Ru(0001) is different and somewhat anomalous compared to that over other transition metal surfaces and, in particular, the turnover ...

Energy‐Resolved Femtosecond Dynamics of Plasmon‐Induced Hole Injection at Au/GaN Heterointerfaces

open access: yesAdvanced Science, EarlyView.
We reveal the spectral signature of ultrafast nonthermal hot‐hole transfer at plasmonic heterointerfaces, which reshapes hot‐carrier relaxation dynamics and significantly enhances hydrogen evolution, providing a mechanistic basis for optimizing hot‐carrier utilization in photocatalysis.

Carrier Transport and Electrical Bandgaps in Epitaxial CrN Layers

open access: yesAdvanced Electronic Materials, EarlyView.
ABSTRACT The transport properties and electrical bandgap of nominally undoped ≈$\approx$75‐nm‐thick CrN layers simultaneously grown on AlN(0001) and AlN(112¯$\bar{2}$2) templates using plasma‐assisted molecular beam epitaxy are investigated. The layers grown on AlN(0001) and AlN(112¯$\bar{2}$2) exhibit (111) and (113) surface orientations, respectively.

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 ...
