Phase Fraction Modulation Enhances Li+/Na+ Diffusion Disparity in Spent LiFePO4 Cathodes for Efficient Lithium Extraction from Brine

open access: yesAdvanced Science, EarlyView.
A direct cascaded utilization strategy for spent LiFePO4 batteries efficiently extracts lithium from brine, embodying the “urban mining” concept. Phase fraction modulation revealed its significant impact on local bond lengths of crystal structure and the Li/Na diffusion energy barrier, identifying the best material (Li0.19FePO4) for lithium extraction.

Thermodynamic performance of SiC-enhanced MicroPCM backfill based on response surface methodology

open access: yesCase Studies in Construction Materials
The functional backfilling in mining achieves synergistic co-mining of deep-earth deposits-geothermal, and the development of functional filling materials with suitable phase change parameters and excellent physicochemical properties is imminent.

Spatially Selective Solvation Chemistry by Local Charge Enrichment for Stable Potassium‐Metal Anodes

open access: yesAdvanced Science, EarlyView.
A MoC/NC functional intermediate medium preferentially interacts with KFSI to reconstruct the interfacial solvation structure and form a KF‐rich inorganic SEI. The synergistic integration of the electronically insulating SEI and MoC/NC suppresses electron tunneling, enables fast and balanced K+/electron transport, and promotes uniform K deposition for ...

Resisting relocation and reconceptualising authenticity: the experiential and emotional values of the Southbank Undercroft London UK [PDF]

open access: yes, 2017
The tagline, ‘You Can’t Move History: You Can Secure the Future’, encapsulated the battle at the heart of the campaign to retain the Southbank Undercroft skate spot in the light of planned redevelopment of the Southbank Centre, London.

Hydrothermal Embedding of Pd Single Atoms Into SnO2 for Efficient CO Oxidation

open access: yesAdvanced Science, EarlyView.
By applying hydrothermal regulation to SnO2‐supported PdO, we achieve atomic dispersion of Pd into the SnO2 lattice, which activates the lattice oxygen neighboring Pd atoms to generate oxygen vacancies and facilitates subsequent O2 activation, thereby promoting CO oxidation to proceed via a low‐energy‐barrier MvK pathway while avoiding CO poisoning ...

Influence of rock heterogeneity on the correlation between uniaxial compressive strength and Brazilian tensile strength

open access: yesScientific Reports
To offer guidance for using Brazilian tensile strength (BTS) to estimate UCS of heterogeneous rocks, this study uses sandstone (fine or coarse grain) and gneiss (0°, 45°, 90° inclined anisotropy) to investigate the influence of grain size or anisotropy ...

Urban space - Public space

open access: yesTạp chí Khoa học Đại học Mở Thành phố Hồ Chí Minh - Khoa học Xã hội, 2011
When mentioning about urban public space, most definitions tend to refer to the social and political aspects of it. This article focuses on examining “public space” from the sociological perspective. Because urban area is a place where individual people from various backgrounds reside together, it is essential that urban public space should be an open,

From urban space to urban history—an introduction

open access: yes, 2020
While interest in urban space in the Roman world has boomed in recent decades, the debate has developed a strong emphasis on conceptual innovation, and this has limited the sensitivity of current discourse to historical change, so that debates about Roman urban space and Roman urban history have been developing without much interaction.

Depicting urban boundaries from a mobility network of spatial interactions: A case study of Great Britain with geo-located Twitter data

open access: yes, 2017
Existing urban boundaries are usually defined by government agencies for administrative, economic, and political purposes. Defining urban boundaries that consider socio-economic relationships and citizen commute patterns is important for many aspects of ...

Conformal Reconfigurable Intelligent Surfaces: A Cylindrical Geometry Perspective

open access: yesAdvanced Electronic Materials, EarlyView.
Cylindrical reconfigurable intelligent surfaces are explored for low‐complexity beam steering using one‐bit meta‐atoms. A multi‐level modeling approach, including optimization‐based synthesis, demonstrates that even minimal hardware can support directive scattering.
