In Situ Growth of 2D Perovskite Nanocrystals to Induce β–Phase of PVDF for Piezoelectric Nanogenerators with Ultra‐High Output Voltage

open access: yesSmall, EarlyView.
In situ grown 2D perovskite nanocrystals embedded in PVDF enable flexible piezoelectric nanogenerators with greatly enhanced β‐phase content and a high d33∗${\mathrm{d}}_{33}^{\mathrm{*}}$ of 35.16 pm/V. The devices deliver up to 66.54 V, exhibit light‐enhanced piezoelectricity, and maintain durability over 12000 cycles, offering a stable energy source

The Pier Luigi Nervi's concrete structure of Palazzetto dello Sport: Modeling and dynamic characterization

open access: yesStructural Concrete, EarlyView.
Abstract This paper presents a numerical and experimental study aimed at the modeling and dynamic characterization of the reinforced concrete structure of the Palazzetto dello Sport in Rome, designed and by Pier Luigi Nervi with Annibale Vitellozzi, and built by Nervi & Bartoli contractors in 1956‐57.

Experimental study on the impact of traffic‐induced vibrations on early‐age concrete

open access: yesStructural Concrete, EarlyView.
Abstract The COUNT (Concreting under Traffic) research project systematically examined the effects of traffic‐induced vibrations on early‐age, hardening concrete—a critical issue for bridge construction and renovation. Traffic closures are often imposed during such projects to mitigate potential damage from vibrations.

Effective Adaptation Options to Alleviate Nuisance Flooding in Coastal Megacities—Learning From Ho Chi Minh City, Vietnam

open access: yesEarth's Future
The economies and livelihoods of many coastal megacities are at serious risk from flooding, despite investments in flood defenses. For instance, in Ho Chi Minh City, the construction of a large‐scale ring‐dike has mitigated negative effects from storm ...

CORR‐DATA: A database of corrosion parameters measured on existing reinforced concrete structures for enhanced structural assessment

open access: yesStructural Concrete, EarlyView.
Abstract The corrosion of reinforcing bars embedded in concrete strongly compromises structural performance over time. However, its detection and quantification remain challenging due to limited comprehensive knowledge of natural corrosion patterns in existing structures.
