Microstructural Evolution Dynamics in Rapid Joule Heating Densification of High‐Nickel Cathodes
Advanced Materials, EarlyView.Introduction of high‐temperature rapid Joule heating combined with two‐step sintering drives full densification while suppressing grain coarsening in high‐Ni cathodes. By activating lattice and grain boundary diffusion over surface diffusion, this approach achieves dense microstructures without excessive grain growth, offering insights into the ...

Spin and Charge Control of Topological End States in Chiral Graphene Nanoribbons on a 2D Ferromagnet
Advanced Materials, EarlyView.Chiral graphene nanoribbons on a ferromagnetic gadolinium‐gold surface alloy display tunable spin and charge states at their termini. Atomic work function variations and exchange fields enabe transitions between singlet, doublet, and triplet configurations.

A "quantum" Ramsey theorem for operator systems [PDF]
, 2016 Let V be a linear subspace of M_n(C) which contains the identity matrix and is stable under the formation of Hermitian adjoints. We prove that if n is sufficiently large then there exists a rank k orthogonal projection P such that dim(PVP) = 1 or k^2.

Characterizing Emerging Detector Materials for Low‐Dose X‐Ray Imaging
Advanced Materials, EarlyView.X‐ray medical imaging requires detectors that deliver images at as low as reasonably possible dose. This perspective outlines a universal characterization framework of X‐ray imaging detectors, suitable for both emerging semiconductor and scintillator materials, introduces a novel unified figure of merit that links dose with resolution, and offers an ...

Periodic rings with commuting nilpotents
International Journal of Mathematics and Mathematical Sciences, 1984 Let R be a ring (not necessarily with identity) and let N denote the set of nilpotent elements of R. Suppose that (i) N is commutative, (ii) for every x in R, there exists a positive integer k=k(x) and a polynomial f(λ)=fx(λ) with integer coefficients ...

Quantum Phase Transitions in Graphene Coupled to a Twisted WSe2 Moiré Ferroelectricity
Advanced Materials, EarlyView.Moiré ferroelectricity in twisted WSe2 (t‐WSe2) breaks graphene's sublattice symmetry, inducing a room‐temperature metal‐insulator transition. Coupling graphene with ferroelectric domains of t‐WSe2 creates local Dirac points and metallic phases with Fermi‐liquid and non‐Fermi‐liquid behavior.

The hybrid mean value of Dedekind sums and two-term exponential sums
Open Mathematics, 2016 In this paper, we use the mean value theorem of Dirichlet L-functions, the properties of Gauss sums and Dedekind sums to study the hybrid mean value problem involving Dedekind sums and the two-term exponential sums, and give an interesting identity and ...
