Black Families, Damned Territories: Anti‐Blackness and Black Motherhood in (White) Portuguese Parliamentary Debates (1995–2001)

open access: yesAntipode, EarlyView., 2023
Abstract The perceptions and representations of whiteness around motherhood, family, and black sexuality reproduce the logic of what Hortense Spillers calls “captive flesh”, controlling understandings about femininity, motherhood, and gender. This debate is guided by the politics of the racial neoliberal agenda that works to control the urban ...

Photonic Floquet–Bloch Oscillations Dominated by Floquet Gauge

open access: yesLaser &Photonics Reviews, EarlyView.
A new type of Bloch oscillations (namely, asymmetric Floquet–Bloch oscillations) whose evolution is biased along the evolution dimension is proposed and visually observed. The Floquet gauge can determine the light broadening to be biased toward the first or second half of the period. These findings reveal a new mechanism for wave packet revival and may

pH‐Dependent Pitting Corrosion in Nickel Thin Films

open access: yesMaterials and Corrosion, EarlyView.
This study investigates pitting corrosion in nickel thin films under varying pH conditions and inhibitor presence. Surface defects and solution chemistry modulate pit formation, while simulations reveal metal redeposition driven by chemical potential gradients at the pit center.

3D Printable Magnetic Soft Actuators–Ink Formulation, Rheological Characterization, and Hydrogel Actuator Prototypes

open access: yesMacromolecular Materials and Engineering, EarlyView.
Magnetic inks for direct ink writing (DIW), a 3D printing technique, are formulated based on acrylamide, iron oxide, and the rheology modifier laponite. They have shear thinning and thixotropic properties. Prototypes printed by DIW, followed by thermal curing, could be magnetically actuated.

Thermo‐Oxidative Aging and Performance Comparison of Recovered, Sustainable, and Virgin Carbon Black in Ethylene Propylene Diene Monomer‐Based Elastomers

open access: yesMacromolecular Materials and Engineering, EarlyView.
This study evaluates sustainable carbon black (sCB) and recovered carbon black (rCB) as substitutes for industrial carbon black N550 in EPDM compounds. Results indicate that sCB closely matches N550 in raw material properties and performance in rubber, while rCB, affected by impurities, alters cross‐linking density, and shows weaker reinforcement ...
