Una geografía para la guerra: narrativas del cerco en Francisco José de Caldas.

open access: yesRevista de Estudios Sociales, 2011
In two emblematic texts–“Estado de la geografía del Virreinato de Santafé” (1807) and “Del influjo del clima sobre los seres organizados” (1808)–Francisco José de Caldas constructs a spatial narrative for the New Granada where the site of siege is ...

High Energy Density Asymmetric Aqueous Supercapacitor Based on a 2D Manganese Carbide as a Positive Electrode

open access: yesAdvanced Functional Materials, EarlyView.
A circular route, involving upcycling of waste surgical masks, affords a Mn‐based layered carbide with porosity, redox activity and low work function. These features enable its effective operation as positive supercapacitor electrode in an aqueous asymmetric supercapacitor delivering 213 Wh L−1 energy density.

Nanothermometry in Living Cells: Physical Limits, Conceptual and Material Challenges

open access: yesAdvanced Functional Materials, EarlyView.
Heat and temperature are fundamental to life. When nanothermometers began probing regions as small as a living cell, they triggered controversial claims of large intracellular temperature gradients. We review physical constraints energy‐conservation, entropy production, thermodynamic fluctuations, and molecular dynamics.

Rupture of Body and Mind in Hiroshima Mon Amour:

open access: yesCrossings, 2023
Alain Resnais has devised a narrative of fractured identity, trauma, and incommunicability in Hiroshima Mon Amour. With its minimal aesthetics, intricate movement and jettisoned conventionality, the film becomes a new map for theorizations in literary ...

Gold Nanoclusters as Dual Agents for Engineering Tumor Vascular Leakiness and Performing Photothermal Therapy

open access: yesAdvanced Functional Materials, EarlyView.
Many cancer nanotherapeutics, while potent, suffer from the inability to escape from the tumor vasculature, especially in the absence of endothelial permeability. In this work, ultrasmall gold nanoclusters could engineer nanomaterials induced endothelial leakiness (NanoEL) and harness strong NIR induced photothermal characteristics to suppress tumor ...

'“A strange enough region wherein to wander and muse": Mapping Clerkenwell in Victorian Popular Fictions' [PDF]

open access: yes, 2019
Drawing on the work of Bertrand Westphal, this essay attempts to perform a geocritical reading of the London district of Clerkenwell. After discussing the spatial turn in the Humanities and introducing a range of spatial critical approaches, the essay ...

Spin‐Dependent Generation of Surface‐Bound Radicals Toward Selective and Long‐Lasting Water Purification

open access: yesAdvanced Functional Materials, EarlyView.
This study develops a novel atomic engineering strategy to fine‐tune the spin state of α‐Fe2O3 catalysts toward a medium‐spin state, thereby modulating peroxymonosulfate activation and selectively yielding surface‐bound radicals. Compared with free radicals, surface‐bound radicals exhibit moderated oxidation potential, extended lifespan, surface ...

Dark Tourism Storytelling and Trauma Narratives: Insights from Romanian Promotional (Tourism) Campaigns

open access: yesJournalism and Media
Dark tourism communication in Eastern Europe remains insufficiently examined, despite the region’s complex post-authoritarian memory landscape and the growing use of storytelling in tourism marketing.
