The power of critique in the time of emergency: on normative fiction and critical fiction

open access: yesJournal of Political Power
This article begins by reflecting on crisis and democracy, arguing that the claim that democracy is in a state of crisis is a normative fiction that sustains rather than transforms extant self-other-world relations. An alternative is to frame the present as ‘the time of emergency’, which implies scope for ‘emergent’ possibilities.

Semantic Modeling in Materials Science and Engineering With Platform MaterialDigital Core Ontology 3.0

open access: yesAdvanced Engineering Materials, EarlyView.
The community‐driven Platform MaterialDigital Core Ontology (PMDco) 3.0 is introduced as a Basic Formal Ontology‐aligned semantic backbone for the processing–structure–properties paradigm in Materials Science and Engineering. Modular engineering, automated releases, and validation workflows are highlighted and key semantic patterns for materials ...

Enhancing Fatigue Crack Growth Resistance in Heterostructured Aluminum Bimetals by Tailored Interface Design

open access: yesAdvanced Engineering Materials, EarlyView.
Different Al/Al bimetals with a single engineered interface reveal how mechanical mismatch governs fatigue crack growth under cyclic loading. Additionally, loading–unloading–reloading tests link the microyielding behavior to the fatigue crack growth resistance, while crack‐path analysis reveals toughening mechanisms at the interface, highlighting ...

The Strange Career of a Black Utopia

open access: yesAnnali di Ca’ Foscari: Serie Occidentale
This essay presents archival information about Charles H. Holmes and argues that his understudied novel, Ethiopia, The Land of Promise (1917), represents an important chapter in the history of Afrofuturism and American speculative fiction.

Sparks from the Tail of a Comet: Historical Materialism and Genetic Imperialism in Octavia E. Butler’s Xenogenesis Novels [PDF]

open access: yesIntersections, 2016
Through a close reading of Octavia Butler’s Dawn (1987), Adulthood Rites (1988) and Imago (1989), this article examines how implicitly decolonialist science fiction is shaped by the socio-historical context of the Cold War.

Distinct Microstructural Characteristic Lengths Defining Notch Fatigue Crack Initiation and Propagation, and Defect Tolerance in Advanced Steels

open access: yesAdvanced Engineering Materials, EarlyView.
Schematic representation of modes of microcrack nucleation, growth and temporary arrestment at different boundaries, with the criteria for crack propagation in three scenarios: (1) large notch, (2) defect/small sharp notch, and (3) long crack. This work revisits and integrates results on the fatigue behavior of advanced bainitic steels (in particular ...

Uniform Amorphization of Crystalline Silicon Surfaces Enabled by Deep Ultraviolet Femtosecond Laser Pulses

open access: yesAdvanced Engineering Materials, EarlyView.
Deep‐UV (258 nm) femtosecond pulses enable uniform amorphous silicon writing on Si(100)/(111) with a six‐fold larger fluence amorphization window than NIR methods. Optimized fluence and overlap yield 20–45 nm uniform and continuous amorphous layers. Microscopy shows sharp interfaces, and real‐time reflectivity reveals nanosecond melt–resolidification ...

A Critique of Njabulo Ndebele’s Criticism of Protest Fiction

open access: yesMediterranean Journal of Social Sciences, 2014
In his critical writings contained in his book, Rediscovery of the Ordinary: Essays on South African Literature and Culture, Njabulo Ndebele propagates the view that black South African writers during the struggle years persistently wrote about the political environment and the conditions in which they found themselves, and are therefore guilty of ...

Superlubricity and Corrosion Inhibition Properties of Solvate Ionic Liquids in Hybrid Carbon Fiber Reinforced Plastic–Steel Interfaces

open access: yesAdvanced Engineering Materials, EarlyView.
Solvate ionic liquids lubrication reduced the coefficient of friction by ∼60% compared to dry sliding, reaching steady‐state values as low as 0.04–0.05. Corrosion weight‐loss measurements in 1 M HCl further demonstrated significant inhibition behavior, with only 100 ppm of [Li(G3)][TFSI] (∼68.5 μL/L) reducing corrosion‐product weight loss by 63 ...

Model‐Guided Design of Paper Membrane Architectures for Controlled Flow and Enhanced Diagnostic Sensitivity

open access: yesAdvanced Engineering Materials, EarlyView.
Geometrical modifications on nitrocellulose membranes can result in observable differences in signal intensity relative to a reference membrane (top and bottom left). Using two reference experiments, we have developed a theoretical model that can reproduce the experimentally observed flow changes and provide information on membrane parameters, e.g ...
