Ferroelectricity in Antiferromagnetic Wurtzite Nitrides

open access: yesAdvanced Functional Materials, EarlyView.
We establish MnSiN2${\rm MnSiN}_2$ and MnGeN2${\rm MnGeN}_2$ as aristotypes of a new multiferroic wurtzite family that simultaneously exhibits ferroelectricity and antiferromagnetism with altermagnetic spin splitting. By strategically substituting alkaline‐earth metals, we predict new materials with coexisting switchable polarization, spin texture, and

The effect of different vigour olive clones on growth, dry matter partitioning and gas exchange under water deficit

open access: yes, 2012
In the last decade, high-density olive planting systems have been developed to facilitate less costly mechanical harvesting and pruning by using straddle harvesters. High-density orchards allow faster production since the first crop of fruit starts a few

Role of Intrinsic Electron Trapping in Negative Charging of Amorphous Alumina

open access: yesAdvanced Functional Materials, EarlyView.
Intrinsic electron trapping in amorphous Al2O3 is examined using hybrid‐DFT models spanning a wide density range. Both spontaneous and thermally activated trapping are identified, with pronounced spontaneous localization in dense, partly crystallized structures.

Genetic effects of inter-tree competition in mixed cocoa stands on yield, vigour and cropping efficiency

open access: yes, 2005
A method developed to assess family competition effects (partner effects) in variety trials was applied to the cocoa tree. The study was conducted in a hybrid trial, involving twelve families of 50 trees each planted in a totally randomised single-tree ...

Timing, light availability and vigour determine the response of Abies alba saplings to leader shoot browsing [PDF]

open access: yes, 2018
Herbivore browsing on tree saplings is a common phenomenon that can cause damage particularly on preferred species. In this study, the combined effects of light availability and timing of browsing on the response of 9-year-old Abies alba saplings were ...

Inoculation of mature pedunculate oaks (Quercus robur) with the root rot fungus Collybia fusipes: relationships with tree vigour and soil factors

open access: yes, 2003
International audienceThe severity of natural infections induced by the root rot fungus Collybia fusipes depends on soil factors. Severely infected trees usually show reduced vigour, as evidenced by poor growth.

Human Gut Bacteria and Lipidic Nanoparticles: Particle Composition Predicts Structural Transformation and Bacterial Biocompatibility

open access: yesAdvanced Functional Materials, EarlyView.
Lipidic nanoparticles (LNPs) were incubated with 21 gut bacteria frequently associated with the human microbiome. SAXS revealed that ∼75% of tested species induced structural transformations in monoolein LNPs, whereas phytantriol and phospholipid formulations remained unaffected.

Mechanical Behavior and Fracture Mechanisms of MXene/PVDF Nanocomponsites: In Situ Characterization and Multiscale Analysis

open access: yesAdvanced Functional Materials, EarlyView.
Multiscale experiments and modeling reveal how Ti3C2Tx MXene nanosheets reinforce PVDF nanocomposites. An optimal MXene loading (∼1 wt.%) nearly doubles tensile strength through efficient stress transfer, flake alignment, and crack‐deflection mechanisms, transforming ductile polymer behavior into a controlled multi‐stage fracture pathway which aligns ...

Use of planting depth and budding height to modify vigour control of Ottawa 3 apple rootstock

open access: yes, 1998
The dwarfing apple rootstock Ottawa 3 (O.3) produces trees slightly too large for high density plantings on fertile soils, but it is more cold hardy and better anchored than Malling 9.

Optoelectronic Synaptic Devices Using Molecular Telluride Phase‐Change Inks for Three‐Factor Learning

open access: yesAdvanced Functional Materials, EarlyView.
Optoelectronic synaptic devices based on solution‐processed molecular telluride GST‐225 phase‐change inks are demonstrated for three‐factor learning. A global optical signal broadcast through a silicon waveguide induces non‐volatile conductance updates exclusively in locally electrically flagged memristors.
