Butterfly eggs prime anti-herbivore defense in an annual but not perennial Arabidopsis species.

Unlike Arabidopsis thaliana, defenses of Arabidopsis lyrata against Pieris brassicae larval feeding are not primable by P. brassicae eggs. Thus, egg primability of plant anti-herbivore defenses is not phylogenetically conserved in the genus Arabidopsis.

NiNbWTiO: Stabilization of the I-Type NiNbO Structure and First Magnetic Study of This Corundum-like Compound.

For the first time, we report on the structural and magnetic properties of a polycrystalline sample of NiNbO from I-type (2), obtained by the partial cosubstitution of Nb by Ti and W. The crystal structure is investigated by combining synchrotron X-ray, neutron, and electron diffraction at room temperature. This I-type structure is derived from the corundum-like NiNbO II-type () and is noncentrosymmetric and polar.

Antipolar 2D Metallicity with Tunable Valence W (5 ≤ ≤ 5.6) in the Layered Monophosphate Tungsten Bronzes [Ba(PO)]WO.

The newly discovered series of layered monophosphate tungsten bronzes (L-MPTB) [Ba(PO)]WO consist of -layer-thick slabs of WO6 octahedra separated by barium-phosphate spacers. They display a 2D metallic behavior confined in the central part of the perovskite slabs. Here, we report the missing = 2 member of this series, containing the rather uncommon W5+ oxidation state.

High Capacitance Porous Ruthenium Nitride Films with High Rate Capability for Micro-Supercapacitors.

The demand for high-performance energy storage devices to power Internet of Things applications has driven intensive research on micro-supercapacitors (MSCs). In this study, RuN films made by magnetron sputtering as an efficient electrode material for MSCs are investigated. The sputtering parameters are carefully studied in order to maximize film porosity while maintaining high electrical conductivity, enabling a fast charging process.

Nanofeather ruthenium nitride electrodes for electrochemical capacitors.

Fast charging is a critical concern for the next generation of electrochemical energy storage devices, driving extensive research on new electrode materials for electrochemical capacitors and micro-supercapacitors. Here we introduce a significant advance in producing thick ruthenium nitride pseudocapacitive films fabricated using a sputter deposition method. These films deliver over 0.
