Superconductivity in Hourglass Dirac Chain Metals (Ti, Hf)IrGe

Advanced Science, EarlyView.
We report the discovery of ternary germanide superconductors MIrGe (M = Ti, Hf) that host hourglass Dirac chains protected by nonsymmorphic symmetry. These compounds exhibit bulk type‐II superconductivity with fully gapped states and preserved time‐reversal symmetry, as confirmed by µSR measurements.

Arc-Disjoint Hamiltonian Cycles in Round Decomposable Locally Semicomplete Digraphs

Discussiones Mathematicae Graph Theory, 2018
Let D = (V,A) be a digraph; if there is at least one arc between every pair of distinct vertices of D, then D is a semicomplete digraph. A digraph D is locally semicomplete if for every vertex x, the out-neighbours of x induce a semicomplete digraph and ...

Graphs with many hamiltonian paths

Involve, a Journal of Mathematics
A graph is \emph{hamiltonian-connected} if every pair of vertices can be connected by a hamiltonian path, and it is \emph{hamiltonian} if it contains a hamiltonian cycle. We construct families of non-hamiltonian graphs for which the ratio of pairs of vertices connected by hamiltonian paths to all pairs of vertices approaches 1. We then consider minimal

Monolayer BX (X = P, As, Sb): Emerging High‐Performance Channel Materials for Advanced Transistors

Advanced Electronic Materials, EarlyView.
Using a first‐principles quantum transport approach, the intrinsic transport properties of 2D BX (X = P, As, Sb) materials are investigated. These materials exhibit high on‐currents and excellent ambipolar symmetry in MOSFET configurations, and break the Boltzmann limit of subthreshold swing in TFETs while maintaining high and symmetric bipolar ...

Intrinsic Strain‐Driven Topological Evolution in SrRuO3 via Flexural Strain Engineering

Advanced Electronic Materials, EarlyView.
A flexural strain platform is developed to isolate intrinsic strain effects on the topological electronic structure in SrRuO3, and demonstrates that the topological properties and associated anomalous Hall effect can be effectively modulated via strain engineering without introducing phase transitions or crystal defects, offering a new approach for ...

Hamiltonian paths passing through matchings in hypercubes with faulty edges

AIMS Mathematics
Chen considered the existence of a Hamiltonian cycle containing a matching and avoiding some edges in an $ n $-cube $ Q_n $. In this paper, we considered the existence of a Hamiltonian path and obtained the following result.

Durable and Efficient Solar CO2‐to‐CO Conversion Enabled by Single‐Atom Ag on Zn3(PO4)2 Cathode Coupled With a GaAs/PtSA@NiOOH Photoanode

Advanced Energy Materials, EarlyView.
Atomic dispersion of Ag within a Zn3(PO4)2 electrocatalysts matrix shows outstanding selectivity for CO evolution, following the intermediate pathway: *CO2 → *COOH → *CO → CO(g) The configuration stabilizes key intermediates and promotes efficient CO2‐to‐CO conversion under electrochemical conditions.
