Elucidating Sodium Ion Storage Mechanisms in Hard Carbon Anodes at the Electronic Level
Advanced Functional Materials, EarlyView.High‐resolution, multi‐frequency continuous wave, and pulsed Electron Paramagnetic Resonance (EPR) spectroscopy uncover the intricate Na ion storage mechanisms in hard carbon. This study reveals the coexistence of Na ion intercalation and solvent co‐intercalation, alongside a subsequent transition of Na ions from ionic to quasi‐metallic to metallic ...

Multivariate Polynomial Values in Difference Sets
, 2020 For $\ell\geq 2$ and $h\in \mathbb{Z}[x_1,\dots,x_{\ell}]$ of degree $k\geq 2$, we show that every set $A\subseteq \{1,2,\dots,N\}$ lacking nonzero differences in $h(\mathbb{Z}^{\ell})$ satisfies $|A|\ll_h Ne^{-c(\log N)^ }$, where $c=c(h)>0$, $ =[(k-1)^2+1]^{-1}$ if $\ell=2$, and $ =1/2$ if $\ell\geq 3$, provided $h(\mathbb{Z}^{\ell})$ contains ...

Heat Conduction Modulation in Incommensurate Twisted Stacking of Transition‐Metal Dichalcogenide
Advanced Functional Materials, EarlyView.The interlayer thermal conductance in twisted bilayer TMDs is initially investigated experimentally by the thermoreflectance method. The overlap of lattice vibrations within individual layers and the interlayer interactions, as elucidated through both Raman spectroscopy and molecular dynamics simulations, are demonstrated to be critical factors in ...

Special non uniform lattice ($snul$) orthogonal polynomials on discrete dense sets of points. [PDF]
arXiv, 1995 Difference calculus compatible with polynomials (i.e., such that the divided difference operator of first order applied to any polynomial must yield a polynomial of lower degree) can only be made on special lattices well known in contemporary $q-$calculus. Orthogonal polynomials satisfying difference relations on such lattices are presented.

On the link between finite difference and derivative of polynomials [PDF]
SSRN Electronic Journal, 2017 The main aim of this paper to establish the relations between forward, backward and central finite (divided) differences (that is discrete analog of the derivative) and partial & ordinary high-order derivatives of the polynomials.MSC 2010: 46G05, 30G25, 39-XXarXiv:1608.00801Keywords: Finite difference, Derivative, Divided difference, Ordinary ...

Comparing various sulfur sources for soybean grown on an acid Oxisol in Brazil
Agronomy Journal, Volume 114, Issue 6, Page 3420-3428, November/December 2022., 2022 Abstract A greenhouse experiment and a 2‐yr field trial were conducted to compare various S sources for soybean [Glycine max (L.) Merr.] grown on an acid Oxisol in Brazil. In the greenhouse, the sources included ammonium sulfate (AMS), monoammonium phosphate with a S ratio = 50:50 of AMS/elemental S (ES) – (AMS + ES), and ES + bentonite containing 90 ...

Skew divided difference operators and Schubert polynomials [PDF]
arXiv, 1997 We study an action of the skew divided difference operators on the Schubert polynomials and give an explicit formula for structural constants for the Schubert polynomials in terms of certain weighted paths in the Bruhat order on the symmetric group. We also prove that, under certain assumptions, the skew divided difference operators transform Schubert ...

Advanced Healthcare Materials, EarlyView.The biocompatibility of alginate dialdehyde (ADA) and gelatin (GEL) hydrogels cross‐linked with human transglutaminase (hTG) is demonstrated in vivo with a high degree of stability and angiogenic potential. The additional enzymatic cross‐linker hTG and the increased concentration improve stability and angiogenic potential. The X‐ray microscopy (XRM) is
