Advanced Functional Materials, EarlyView.EuSc₂Te₄, an antiferromagnetic semiconductor, exhibits a nonlinear Hall effect (NLHE) characterized by quadratic current–voltage behavior. Combined experimental and theoretical studies reveal that this NLHE is linked to its antiferromagnetism and involves contributions from the quantum metric.

A description of the topology of free topological vector spaces [PDF]
arXiv, 2018 The free topological vector space (tvs) $\mathbb{V}(X)$ over a Tychonoff space $X$ is defined and studied by Sidney A. Morris and the author in [2]. A description of the topology of the free tvs $\mathbb{V}(X)$ over a uniform space $X$ is given in [1].

Interfacial Interaction‐Mediated Regulation of Metal Oxidation States for Enhanced CO2 Reduction
Advanced Functional Materials, EarlyView.A hybrid strategy is employed to optimize bismuth–oxygen interactions, precisely regulating interfacial bismuth–oxygen bonds during topochemical synthesis. This leads to vanadium oxynitride‐bismuth catalyst exhibiting high Faradaic efficiency and durability for formate production, attributed to enhanced reaction thermodynamics and kinetics.

Spin‐Selective Anisotropic Magnetoresistance Driven by Chirality in DNA
Advanced Functional Materials, EarlyView.It is shown that magnetoresistance (MR) measurements carried out as a function of angular dependence between the magnetic field and a chiral (DNA) interface provide a valuable new insight into the charge transport mechanism associated with the chiral‐induced spin selectivity (CISS) effect.

Advanced Functional Materials, EarlyView.A spin group (SG)‐based mechanism is proposed to realize a single pair of Weyl points. PT‐symmetric nodal lines (NLs) persist under T‐breaking, protected by the combination of SG and P symmetry. When considering spin‐orbit coupling, the SG‐protected NL will split into Weyl points, which will also induce anomalous transport phenomena arising from ...

Knowledge space theory and union-closed sets conjecture [PDF]
Songklanakarin Journal of Science and Technology (SJST), 2016 The knowledge space theory provides a framework for knowledge management. One of major problems is to find core information for a body of knowledge.

Fractional Skyrmion Tubes in Chiral‐Interfaced 3D Magnetic Nanowires
Advanced Functional Materials, EarlyView.In chiral 3D helical magnetic nanowires, the coupling between the geometric and magnetic chirality provides a way to create topological spin states like vortex tubes. Here, it is demonstrated how the breaking of this coupling in interfaced 3D nanowires of opposite chirality leads to even more complex topological spin states, such as fractional ...

Semi-h-Open Sets and Semi-h-Continuity in Topological Spaces [PDF]
Al-Rafidain Journal of Computer Sciences and MathematicsIn this study, we generalized two known open sets called semi-open and h-open sets to find a new type called semi-h-open set in topological space We have presented the relationship of several famous open sets to this set.
