Residual‐Lithium‐to‐LiF Conversion Enables a LiF–Fluorinated Carbon Interphase for Reconstruction‐Resistant Ni‐Rich Cathodes

open access: yesAdvanced Functional Materials, EarlyView.
A fluorine‐rich acrylate monomer (PFHEA) was solvent‐free applied to NCM90 and thermally decomposed under Ar to convert residual lithium into LiF and form a pre‐built LiF/fluorinated amorphous carbon (LiF/FC) interphase. The LiF/FC layer suppresses NiO rock‐salt reconstruction and microcrack propagation, lowers interfacial resistance, and improves Li ...

Obtaining the Fourier spectrum via Fourier coefficients

open access: yes
The Fourier spectrum is a family of dimensions that interpolates between the Fourier and Hausdorff dimensions and is defined in terms of certain energies which capture Fourier decay.

On the arithmetic nature of coefficients of multiplicative eta-functions

open access: yesВестник Самарского университета: Естественнонаучная серия
In the article we study the arithmetic nature of the coefficients of multiplicative eta-products, also called McKay functions. For some functions it is possible to establish Hecke correspondence between the coefficients of McKay and Hecke grossen ...

Electrode and Microstructure Dependence of Oxygen Diffusion in Ferroelectric Hafnium Zirconium Oxide Thin Films

open access: yesAdvanced Functional Materials, EarlyView.
Significant nanoscale oxygen diffusion coefficient variations are measured in ferroelectric hafnium zirconium oxide films with grain boundaries and electrode interfaces exhibiting values 104 times larger than the grain cores. Overall coefficients are 10X larger for films prepared with metal nitride electrodes compared to refractory metals. New insights

Oversampling of Fourier Coefficients: Theory and Applications [PDF]

open access: yes, 2016
The objective behind the proposal studies around oversampling of Fourier coefficients and their applications. I intend to study how oversampling of Fourier coefficients can be used for hiding messages.

Some remarks on the Melnikov function

open access: yesElectronic Journal of Differential Equations, 2002
We study the Melnikov function associated with a periodic perturbation of a differential equation having a homoclinic orbit. Our main interest is the characterization of perturbations that give rise to vanishing or non-vanishing of the Melnikov function.

An Optimal Pufferfish Privacy Mechanism for Temporally Correlated Trajectories

open access: yesIEEE Access, 2018
Temporally correlated trajectories are ubiquitous, and it has been a challenging problem to protect the temporal correlation from being used against users' privacy.

High‐Index, Low‐Loss Optical Material Platforms for Ultra‐Broadband Ultraviolet‐to‐Visible Achromatic Metalenses

open access: yesAdvanced Functional Materials, EarlyView.
An integrated material platform combining engineered SiNx thin films and printable ZrO2 nanoparticle‐embedded resin enables broadband achromatic metalenses from the ultraviolet to visible range. The demonstrated meta‐optics achieve near‐diffraction‐limited focusing with minimal chromatic aberration.

The sufficient condition of embedding in the Lorentz space

open access: yesҚарағанды университетінің хабаршысы. Математика сериясы, 2016
In this paper considered the transformation of a series of Fourier-Price in the form k - th difference of the Fourier-Price coefficients. In addition, obtained a sufficient condition the belonging of the function f in a two - parameter Lorentz space in ...
