High‐performance thermoelectric calcium cobaltite nanoribbon ceramic via electrospinning and dual spark plasma texturing

Journal of the American Ceramic Society, Volume 108, Issue 2, February 2025.
Abstract High‐performance polycrystalline calcium cobaltite ceramic was synthesized via electrospinning of nanoribbons, followed by dual‐process compaction using spark plasma sintering and edge‐free spark plasma texturing. The combination of nanoribbon electrospinning and this multistage sintering technique was employed for the first time and resulted ...

The linear $\protect \mathfrak{n}(1|N)$–invariant differential operators and $\protect \mathfrak{n}(1|N)$–relative cohomology

Comptes Rendus. Mathématique, 2020
Over the $(1,N)$-dimensional supercircle $S^{1|N}$, we classify $\mathfrak{n}(1|N)$-invariant linear differential operators acting on the superspaces of weighted densities on $S^{1|N}$, where $\mathfrak{n}(1|N)$ is the Heisenberg Lie superalgebra.

Hopf algebra structure of symmetric and quasisymmetric functions in superspace [PDF]

J. Combin. Theory Ser. A 166 (2019), 144-170, 2019
We show that the ring of symmetric functions in superspace is a cocommutative and self-dual Hopf algebra. We provide formulas for the action of the coproduct and the antipode on various bases of that ring. We introduce the ring sQSym of quasisymmetric functions in superspace and show that it is a Hopf algebra.

Advances in Texturing and Thermoelectric Properties of a Calcium Cobaltite Ceramic via Combined Spark Plasma Sintering and Spark Plasma Texturing

Advanced Functional Materials, Volume 35, Issue 1, January 2, 2025.
Calcium cobaltite [Ca2CoO3‐δ]0.62[CoO2] emerges as a promising p‐type thermoelectric material suitable for high‐temperature applications in the air. Employing a combination of spark plasma sintering and edge‐free spark plasma texturing, a highly textured polycrystalline ceramic is successfully fabricated.

Jack Polynomials in Superspace [PDF]

Communications in Mathematical Physics, 2003
This work initiates the study of {\it orthogonal} symmetric polynomials in superspace. Here we present two approaches leading to a family of orthogonal polynomials in superspace that generalize the Jack polynomials. The first approach relies on previous work by the authors in which eigenfunctions of the supersymmetric extension of the trigonometric ...

Giant Topological Hall Effect and Colossal Magnetoresistance in Heusler Ferromagnet near Room Temperature

Advanced Materials, Volume 37, Issue 3, January 22, 2025.
Ferromagnetic shape memory Heusler alloy Ni2Mn1.4In0.6 exhibits colossal magnetoresistance (CMR) and giant topological Hall effect (THE) near room temperature, which is attributed to the enhanced spin chirality emerging from the formation of domains and domain walls, which in turn resulted from the combined effect of magnetic field induced martensite ...

Minkowski superspaces and superstrings as almost real-complex supermanifolds

, 2012
In 1996/7, J. Bernstein observed that smooth or analytic supermanifolds that mathematicians study are real or (almost) complex ones, while Minkowski superspaces are completely different objects. They are what we call almost real-complex supermanifolds, i.
