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 ...

Spark plasma sintering of hard wear‐resistant graphene nanoplatelet–reinforced TiB2 + SiC composites from TiC–B4C–SiC

Journal of the American Ceramic Society, Volume 107, Issue 12, Page 8521-8529, December 2024.
Abstract Graphene nanoplatelet (GNP)–reinforced TiB2 + SiC composites were fabricated by reactive spark plasma sintering (SPS) from a TiC–B4C–SiC powder mixture with equal‐volume percentages, optimizing their SPS temperature and evaluating their unlubricated sliding wear against diamond. First, it is shown that during the heating ramp of the SPS cycle,
