Investigations on Three‐Dimensional (3D) Woven Carbon Fiber Electrodes for Vanadium Redox Flow Batteries

open access: yesChemElectroChem, Volume 13, Issue 7, 1 April 2026.
Three‐dimensional orthogonal woven electrodes fabricated from continuous carbon filaments with systematically varied warp and weft densities were investigated for their electrochemical performance in vanadium redox flow cells. The relationships between individual resistance components and key electrode parameters—including total yarn, warp, weft, and ...

Il culto di Minerva nel bresciano. Geografia e forme del sacro fra interpretatio e innovazione [PDF]

open access: yes, 2014
The paper considers the evidence of the cult of Minerva in the Brescia area in Roman times. The analysis of the cultual data in the context of the more general archaelogical and territorial framework reveals a complex and diverse scenario.

A Dynamic Model for Extreme Hourly Precipitation

open access: yesEnvironmetrics, Volume 37, Issue 3, April 2026.
ABSTRACT Despite the scarcity of comprehensive studies at a global scale, many regional analyses report increases in extreme hourly precipitation values. The growing interest in assessing trends in extreme hourly precipitation has outpaced the development of new statistical tools tailored to their features. Typical analyses employ Extreme Value Theory (

CTAB‐Engineered Electro‐Blown PVDF Nanofibrous Air Filters with Enhanced Charge Retention, Filtration Efficiency, and Antibacterial Functionality

open access: yesMacromolecular Materials and Engineering, Volume 311, Issue 4, April 2026.
CTAB‐assisted electroblowing enables controlled fabrication of PVDF nanofibers with reduced fiber diameter, enhanced β‐phase formation, and improved electret behavior, resulting in high‐efficiency particulate capture with low pressure drop and antibacterial functionality.

Tailoring Crystallographic Texture Through Direct Ink Writing of Piezoelectric Ceramics

open access: yesJournal of the American Ceramic Society, Volume 109, Issue 4, April 2026.
A novel additive manufacturing approach is demonstrated, using needle‐like template particles with preferred crystallographic orientation that align during additive manufacturing. This combines freedom in geometrical design with local crystallographic control that can increase functional properties, here demonstrated as a doubling of the piezoelectric ...

Un Impianto artigianale per la lavorazione del ferro dall’antica Sulky (Sardegna) [PDF]

open access: yes, 2010
La tradizione degli studi sul fenomeno coloniale in Occidente vede nel rifornimento di materie prime, tra le quali i metalli, una fondamentale prerogativa che giustifica l’adozione di particolari strategie insediative, spiegando quindi in parte la spinta

Observation of Relativistic Domain Wall Motion in Amorphous Ferrimagnets

open access: yesAdvanced Functional Materials, Volume 36, Issue 23, 19 March 2026.
Domain walls in ferrimagnets and antiferromagnets move as relativistic sine‐Gordon solitons, with the spin‐wave velocity setting their speed limit. Such relativistic domain‐wall motion is demonstrated in amorphous GdFeCo near angular momentum compensation, where current‐driven walls reach 90% of the 2 kms−1 spin‐wave speed, enabling ultrafast, device ...
