Optimal Mechanical Properties and High Cellular Proliferation on Hybrid PCL/HaP/Col/SA Scaffolds for Tissue Engineering

Surface and Interface Analysis, Volume 57, Issue 8, Page 659-665, August 2025.
ABSTRACT This study determines the mechanical properties, surface features, and the cellular response of mesenchymal cells of an electrospun scaffold of polycaprolactone (PCL) combined with hydroxyapatite (HaP), collagen (Col), and sodium alginate/poly (vinyl alcohol) (SA/PVA) for applications in tissue engineering to restore injured tissue.

Processability and properties of cubic‐BaTiO3/poly(vinylidene fluoride) composites for additive manufacturing: From powder compounding to 3D‐printed parts

Polymer Composites, Volume 46, Issue 8, Page 7346-7361, 10 June 2025.
Processing and characterization of the BaTiO3/poly(vinylidene fluoride) 3D‐printed parts. Abstract Poly(vinylidene fluoride) (PVDF) is a piezoelectric and thermoplastic material with great potential for additive manufacturing (AM) applications. Using barium titanate (BaTiO3) as filler, PVDF‐based composite materials were developed, characterized, and ...

Differential xylem phytohormone export from dry and wet roots during partial rootzone drying is independent of shoot‐to‐root transport in soybean

Physiologia Plantarum, Volume 177, Issue 3, May/June 2025.
Abstract Different phytohormones can act as root‐to‐shoot signalling molecules in response to soil drying. Recent findings suggest that root ABA levels are predominantly leaf‐sourced and not locally synthesized, thus, ABA exported from the roots in the xylem is mostly recycled from the shoot.

River Mouth Hydrodynamics: The Role of the Outlet Geometry and Transient Tidal and River Discharge Conditions on the Jet Structure

Journal of Geophysical Research: Oceans, Volume 130, Issue 1, January 2025.
Abstract The hydrodynamics of river mouths are the result of a complex interaction between river flow, tidal conditions, and outlet geometry. This complex interaction of factors shapes the jet that flows onto the continental shelf and influences the dynamics of these areas.

Gender‐Based Differences in the Biomechanical Behavior of the Thorax During CPR Maneuvers

International Journal for Numerical Methods in Biomedical Engineering, Volume 40, Issue 12, December 2024.
Cardiopulmonary resuscitation (CPR) is a common emergency procedure for cardiac arrest. This study presents numerical experiments simulating this maneuver in both genders to determine the optimal location and force for chest compressions. By analyzing deformation and stress, this investigation demonstrates that the ideal compression point is lower on ...
