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

Small, 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

Lithosphere structures dynamics in the central High Atlas (Morocco) by seismic tomography and gravimetric data

Geodesy and Geodynamics, 2019
We investigate sedimentological and tectonic processes at the central High Atlas, in order to understand their functioning and to build a geodynamic model that placed the area in its current geological frame.

Concrete in architecture: Redefining form, space, function, and insights from bibliometric analysis

Structural Concrete, EarlyView.
Abstract Concrete has become a cornerstone in architectural and engineering innovation, as it seamlessly integrates structural performance with artistic expression. Its evolution from ancient opus caementicium to contemporary ultra‐high‐performance concrete illustrates its adaptability to the change in technological, environmental, and design paradigms.

Experimental evaluation of reinforced concrete columns produced with natural perlite aggregates under cyclic loading

Structural Concrete, EarlyView.
Abstract A total of four reinforced concrete (RC) columns were tested to compare the structural capacities of RC columns produced by natural perlite aggregates and conventional concrete. The structural performance of the RC columns made from natural perlite aggregates was compared to conventional RC columns regarding the same concrete strength levels ...
