“We Charge Genocide”: Revisiting black radicals’ appeals to the world community1

Radical Americas, 2018
In 1951, black radical William Patterson presented the United Nations with a petition, emblazoned with the title We Charge Genocide. The document charged the US government with snuffing out tens of thousands of black lives each year, through police ...

From the rails to the courts: railway workers fighting for rights

Revista Mundos do Trabalho, 2021
The growing organization of the working class between the 1950s and the 1960s is considered one of the factors that triggered the 1964 civil-military coup. Among urban workers, the railway class was severely repressed by the State and the Federal Railway

Bone‐Inspired Recyclable Composites for Damage‐Tolerant Circular Materials

Advanced Functional Materials, EarlyView.
Bone‐inspired architected composites are developed by combining osteon‐like reinforcements with a recyclable Elium thermoplastic matrix. The hierarchical architecture redirects cracks and promotes energy dissipation, while enabling recovery of intact, aligned, load‐bearing reinforcement units that retain their original stiffness, revealing a route ...

The Tale of Two Civil Societies: Comparing disability rights movements in Nicaragua and Uruguay

Disability Studies Quarterly, 2014
The UNCRPD is unique amongst international rights instruments because it empowers civil society organizations to represent the rights-bearers themselves—persons with disabilities.

Sub‐Nanometer Curvature Unlocks Quantum Orbital Flexoelectricity in Graphene

Advanced Materials, EarlyView.
In self‐assembled, reproducible, large‐area, quasi‐pristine graphene nanowrinkles, extreme curvature forces out‐of‐plane π‐electrons toward hybridization, driving a transition from classical to quantum orbital flexoelectricity. As curvature approaches the fundamental physical limit set by the C─C bond length, the resulting polarization increases by ...

Disability Studies, Disability Services: Would Addressing the Gap in Professional Communication Impact Implementation of the ADA?

Disability Studies Quarterly, 2015
The Civil Rights Movement spurred social changes that impacted many, including people with disabilities; while the ADA ideally provides the groundwork for greater accessibility, accessibility is an ideal that is not yet fully realized.

Autonomous Folding of Soft Matter From Living Polymers

Advanced Materials, EarlyView.
Origami structures are endowed with “living” polymer creases that grow, remodel, and stiffen in response to nutrient solutions. This post‐fabrication growth enables autonomous folding, iterative regrowth, and mechanical tuning involving origami assemblies, such as cranes, Miura‐ori tessellations, rigid and non‐rigid square‐twist patterns, establishing ...

The widening partisan gap in legislative support for civil rights in the United States

Nature Communications
The history of civil rights legislation offers a window into how American democracy codified social justice over time, and whether this process unfolded gradually or through punctuated shifts. Sixty years after the civil rights movement, we apply natural

Redox‐Confined Interfacial Polymerization Enables Mechanically Robust and Self‐Adhesive Nanofilms

Advanced Materials Interfaces, EarlyView.
Redox‐confined polymerization of a simple thiol monomer at a water‐organic interface generates robust freestanding films with nanoscale thickness. The resulting disulfide‐crosslinked nanofilms combine high stiffness with intrinsic adhesion to soft substrates, enabling conformal contact with artificial skin without additional functionalization.

Testing and Simulation of Multilayer Polyvinylidene Fluoride‐Based Piezoelectric Energy Harvester Devices

Advanced Materials Technologies, EarlyView.
The study considers the use of polymer/dielectric‐based multilayers piezoelectric Energy Harvesters (EH) to produce an output voltage and current, by exploiting the mechanical energy provided by human organs movements. In particular, the heart motion is considered from the kinematic viewpoint, and a multiphysics theoretical model is developed to assess
