A non-linear creep constitutive model for salt rock based on fractional derivatives

open access: yesThermal Science, 2019
The creep property of the salt rock is an important determinant of deep underground repository of energy storage for long-term operatio. Starting from fractional derivative, this paper proposes a new concept of super Abel dashpot based on Abel dashpot ...

Synergistic Coupling of Host and Electrolyte Achieving 1270 Wh L−1 in Anode‐Free Lithium Metal Batteries

open access: yesAdvanced Materials, EarlyView.
A synergistic combination of a highly reversible host and a commercially viable carbonate‐rich electrolyte enables simultaneous stabilization of both anode and cathode interfaces in anode‐free lithium metal batteries. This integrated strategy delivers exceptional reversibility and a record volumetric energy density of 1270 Wh L−1 (including package) in

LEAD: Literature Enhanced Ab Initio Discovery of Nitride Dusting Layers for Enhanced Tunnel Magnetoresistance and Lower Resistance Magnetic Tunnel Junctions

open access: yesAdvanced Materials, EarlyView.
Magnetic tunnel junctions (MTJs) using MgO tunnel barriers face challenges of high resistance‐area product and low tunnel magnetoresistance (TMR). To discover alternative materials, Literature Enhanced Ab initio Discovery (LEAD) is developed. The LEAD‐predicted materials are theoretically evaluated, showing that MTJs with dusting of ScN or TiN on ...

Observation of oscillatory relaxation in the Sn-terminated surface of epitaxial rock-salt SnSe $\{111\}$ topological crystalline insulator

open access: yes, 2017
Topological crystalline insulators have been recently predicted and observed in rock-salt structure SnSe $\{111\}$ thin films. Previous studies have suggested that the Se-terminated surface of this thin film with hydrogen passivation, has a reduced ...

Impact of Anode to Cathode Crossover in Lithium‐metal Batteries With High‐Nickel Cathodes

open access: yesAdvanced Materials, EarlyView.
Anode‐to‐cathode chemical crossover is identified as a critical degradation mechanism in lithium‐metal batteries. Full‐cell experiments with high‐Ni layered oxide cathodes and localized high‐concentration electrolytes reveal accelerated cathode impedance growth and CEI thickening driven by lithium‐metal anodes. The findings underscore the importance of

Oil and Nitrate-Salt Coolant Trade-Offs With Crushed-Rock Heat Storage and CSP

open access: yesSolarPACES Conference Proceedings
The large-scale use of wind or solar results in collapse of electricity prices at times of large wind or solar production.  Addition of heat storage to Concentrated Solar Power (CSP) plants enables (1) storing heat at times of high solar input, excess ...

Mining revival [PDF]

open access: yes, 2010
In relation to its size the United Kingdom (UK) is remarkably well-endowed with mineral resources as a result of its complex geological history. Their extraction and use have played an important role in the development of the UK economy over many years ...

New electronic orderings observed in cobaltates under the influence of misfit periodicities

open access: yes, 2010
We study with ARPES the electronic structure of CoO2 slabs, stacked with rock-salt (RS) layers exhibiting a different (misfit) periodicity. Fermi Surfaces (FS) in phases with different doping and/or periodicities reveal the influence of the RS potential ...
