Room‐Temperature Ferromagnetism in an Iron‐Based Zeolitic Imidazolate Framework Glass

Advanced Science, EarlyView.
Vitrification engineering is employed to induce magnetic ordering transformation from room‐temperature antiferromagnetism of crystalline Fe‐ZIF to weak ferromagnetism of its glassy counterpart. The structure‐magnetism relationships are investigated to provide a valuable guide for tuning magnetic properties and designing of MOFs magnets.

Lattice representations of Heisenberg groups [PDF]

Mathematische Annalen, 2000
In this article, we prove that a lattice representation of the Heisenberg group $H_{\mathbb R}^{(g,h)}$ associated to a lattice $L$ and a positive definite symmetric half-integral matrix M of degree $h$ is unitarily equivalent to the direct sum of $(det 2M)^g$ copies of the Schroedinger representation of $H_{\mathbb R}^{(g,h)}$.

Interplay of Backbone Conformation, Morphology and Thermoelectric Properties of Benzodifuranone‐Isatin Acceptor Polymers

Advanced Electronic Materials, EarlyView.
Modification of polymer backbone via halogenation and comonomer selection leads to conjugated backbones of different stereoelectronic properties, thin film morphologies, and electrical characteristics. The interplay of conformational isomerism, coplanarity, backbone curvature, backbone orientation, and ordering in thin films, electrical conductivity ...

Invariant Translators of the Heisenberg Group [PDF]

The Journal of Geometric Analysis, 2020
AbstractWe classify all the translating solitons to the mean curvature flow in the three-dimensional Heisenberg group that are invariant under the action of some one-parameter group of isometries of the ambient manifold. We provide a complete classification for any canonical deformation of the standard Riemannian metric of the Heisenberg group.

What to Make and How to Make It: Combining Machine Learning and Statistical Learning to Design New Materials

Advanced Intelligent Discovery, EarlyView.
Combining machine learning and probabilistic statistical learning is a powerful way to discover and design new materials. A variety of machine learning approaches can be used to identify promising candidates for target applications, and causal inference can help identify potential ways to make them a reality.

An improved Hardy type inequality on Heisenberg group

Journal of Inequalities and Applications, 2011
Motivated by the work of Ghoussoub and Moradifam, we prove some improved Hardy inequalities on the Heisenberg group ℍ n via Bessel function.

Ion‐Pairing‐Modulated Diradical Properties in Partially Conjugated Negatively Charged π‐Electronic Systems

Chemistry – A European Journal, EarlyView.
A quinonoidal dipyrrolyldiketone boron complex with an orthogonally arranged catechol unit in the dianionic form exhibited diradical properties, as observed from the singlet–triplet energy gaps (ΔEST) that were modulated by coexisting countercations. ΔEST values were controlled by the bridging boron moieties in the dianion diradicals.

Existence for (p, q) critical systems in the Heisenberg group

Advances in Nonlinear Analysis, 2019
This paper deals with the existence of entire nontrivial solutions for critical quasilinear systems (𝓢) in the Heisenberg group ℍn, driven by general (p, q) elliptic operators of Marcellini types.

Selective Modification of the Product Profile of Biocatalytic Hydrolyzed PET via Product‐Specific Medium Engineering

ChemSusChem, Volume 18, Issue 6, March 15, 2025.
The product profile of enzymatically hydrolyzed PET can be modified by medium engineering and thereby adapted to a desired product. TPA, MHET or BHET can be forced as the predominant product using a basic pH (blue), 25 % ethylene glycol (EG) and IsPETasewt (green) or ≥25 % EG and LCCICCG (pink), respectively.

Barley Leaf Area and Leaf Growth Rates Are Maximized during the Pre-Anthesis Phase

Agronomy, 2015
Leaf developmental traits are an important component of crop breeding in small-grain cereals. Surprisingly, little is known about the genetic basis for the differences in barley (Hordeum vulgare L.) leaf development. The two barley row-type classes, i.e.
