Ferroelectricity in Antiferromagnetic Wurtzite Nitrides
Advanced 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

Polarizable Vanadium Dipoles Promote Water Dissociation on Vanadium‐Based Metal Organic Framework
Advanced Functional Materials, EarlyView.The polarization of unpaired V 3d electrons weakens the H─O bond to improve water dissociation by the dual Vδ+:O─H and Pλ−:H─O coupling hydrogen bonds formation and relaxation. P@V‐MOF electrocatalyst shows low overpotentials (94 mV in acid, 178 mV in neutral, and 77 mV in alkaline solutions) with excellent stability for effective overall water ...

Late Iron Age decorated coarse ware in central‑eastern Lombardy (Northern Italy) [PDF]
Studia HercyniaThis paper delves into Late Iron Age decorated coarse ware originating from the present day province of Bergamo in central Lombardy. During protohistoric time, this region served as a borderland and a nexus connecting extensive cultural spheres ...

Role of Intrinsic Electron Trapping in Negative Charging of Amorphous Alumina
Advanced 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.

Tumultuous materials. Decorated coarse ware in Late Iron Age Emilia [PDF]
Studia HercyniaIn the Emilian Po plain, during the Late Iron Age (4th and 3rd century BCE), an unprecedented and heteroge neous class of handmade coarse and decorated ceramics emerged in certain sites.

Piuforesta. Il bosco di Piubega e la foresta planiziale padana
Ri-vista: Ricerche per la Progettazione del PaesaggioThe Po Valley, once rich in forests, has undergone a drastic reduction in forest cover over the centu-ries due to the advent of modern agriculture. Today, the only remaining traces of the original forests are found along the riverbanks and in a few ...

Analysis of the severe flood of 13t-16th October 2000 in Piedmont (Italy)
Cuadernos de Investigación Geográfica, 2013 During the 13th-16th of October 2000 a disastrous flood occurred in the whole Piedmont associated with heavy rainfall over the North-Western Alpine chain in successive episodes spanning the whole period. The event was originated by a Southern, strong and

Advanced Functional Materials, EarlyView.In MOCVD MoS2 memristors, a current compliance‐regulated Ag filament mechanism is revealed. The filament ruptures spontaneously during volatile switching, while subsequent growth proceeds vertically through the MoS2 layers and then laterally along the van der Waals gaps during nonvolatile switching.

Doppler radar wind field retrieval over the Po Valley [PDF]
Natural Hazards and Earth System Sciences, 2006 Although methods of using multiple Doppler radars to study wind fields have long been proposed, and many research studies have been made, very few operational radar operators adopt methods which require the use of specific scanning strategies to allow ...
