Some Classes of Topological Spaces with Unique Quasi-Uniformity

open access: yes, 1986
We follow P. Fletcher and W. F. Lindgren's work in the study of topological spaces with a unique quasi-uniformity by generalizing some of their results and constructing larger classes of uqu spaces which contain some of their examples as a particular ...

Quasi-ordered plasmonic metasurfaces with unclonable stochastic scattering for secure authentication

open access: yesNature Communications
Quasi-order in structural coloration, as observed in nature, offers intrinsic, unclonable near-field stochastic fingerprints while preserving far-field uniform colors.

Quasi-uniform Structures in Linear Lattices

open access: yesRocky Mountain Journal of Mathematics, 1993
This paper concerns normed linear spaces defined over the field of real numbers. The authors call a normed lattice in which the parallelogram law holds for positive elements an \(E\) space, and they call a nonnegative sublinear function \(q\) a quasi-norm provided that if \(q(x)= q(-x)= 0\) then \(x= 0\).

Reconstructing Residual‐Solvent‐Involved Li+ Coordination in PVDF‐HFP Polymer Electrolytes for Stable Lithium Metal Batteries

open access: yesAdvanced Functional Materials, EarlyView.
2,2,2‐trifluoroethanamide‐mediated coordination regulation reconstructs the local Li+ environment in PVDF‐HFP polymer electrolytes by weakening residual DMF‐dominated coordination and promoting TFSI−‐involved anion‐rich solvation. This strategy facilitates Li+ migration and interfacial desolvation, promotes the formation of a thin inorganic‐rich SEI ...

New Insights into Coating Uniformity and Base Sheet Structures

open access: yes, 2009
Base sheet structures, such as surface roughness and mass density distribution (formation), have been known to affect coating uniformity. However, the literature is not necessarily consistent in determining which structure controls coating uniformity ...

Scaling up Tubular Redox Flow Batteries: Electrode Configuration Effects on Current Distribution and Performance

open access: yesECS Advances
Redox flow batteries are a promising energy storage technology for mitigating the intermittency of renewable energy sources. Despite certain technologies have progressed to partial commercialization, high system cost remains a barrier to broader adoption.

Ontological Prerequisites for the Emergence of Scientific Cosmology in the Context of the Emergence and Development of the Scientific Thinking [PDF]

open access: yesФилософия и космология
The article argues that scientific cosmology, the study of the Universe’s origin, evolution, and structure, remains an essential and integral part of scientific thinking.

Anisotropic Phonon Dynamics and Directional Transport in Actinide Van der Waals Semiconductor Uranium Triselenide

open access: yesAdvanced Functional Materials, EarlyView.
USe3 is introduced as an actinide van der Waals semiconductor that mirrors the quasi‐one‐dimensional physics of transition‐metal trichalcogenides. Polarization‐resolved Raman spectroscopy on exfoliated flakes maps strong in‐plane phonon anisotropy and strain‐tunable mode shifts.
