Biodegradable Chitosan Films as Green Resists for Gold Nanowires Fabrication Through AFM‐Based Nanolithography

open access: yesAdvanced Materials Interfaces, EarlyView.
Schematic illustration of a sustainable nanofabrication process: chitosan derived from natural sources is used as a biodegradable thin film resist, patterned via Constant Pulse‐Assisted Force Lithography (CP‐AFL) to create tunable nanogrooves. These grooves template gold nanowire formation, enabling high‐resolution nanopatterning under ambient ...

Sensitive and Spatially‐Resolved Electrochemiluminescence via Micropatterning

open access: yesAdvanced Materials Interfaces, EarlyView.
The use of a simple silica nanoparticle surface coating and patterning process can transform ordinary gold electrodes into multiplexed ECL sensing electrodes. Through spatially confined droplet formation and local ECL emission, it is possible to perform multiple analyses simultaneously from individual locations as well as intensify the ECL signal by as

Developing the ‘Control Imaginary’: TIME Magazine’s Symbolic Construction of Digital Technologies

open access: yesInternational Journal of Communication, 2020
This article discusses the shifting representations of control over and via ICTs on the cover of TIME magazine (1950‒2017). We focus on the subject positions and forms of agency the magazine ascribes to different social actors and on the solutions ...

A fotografia numa era de política de massas latinoamericana: as revistas S.Paulo (Brasil, 1936) e Rotofoto (México, 1938)

open access: yesL'Ordinaire des Amériques, 2015
The aim of this article is to compare two illustrated magazines that had a short life in the 1930s in their respective countries: S.Paulo (Brazil 1935/1936), and, as a counterpoint, Rotofoto (Mexico 1938).

Multiscale Microscopy via Automation: Dual Magnification Environmental Scanning Electron Microscopy Imaging by Frame Alternation

open access: yesAdvanced Materials Technologies, EarlyView.
An automation interface for environmental scanning electron microscopy (ESEM) enables simultaneous, interlaced data sets via frame‐by‐frame parameter changes. Demonstrated on oscillatory hydrogen oxidation over cobalt (Co) foil, dual‐magnification imaging bridges mesoscopic to microscopic length scales, capturing alternating views of surface dynamics ...

Degradable Magnetic Composites from Recycled NdFeB Magnets for Soft Actuation and Sensing

open access: yesAdvanced Robotics Research, EarlyView.
This work presents a degradable soft magnetic composite made from recycled NdFeB particles embedded in a gelatin‐based organogel. The material is processed into magnetic sensors and soft robotic components, which can later be dissolved in a green solvent to recover NdFeB magnetic particles.

Venezuelan Political Thinking as Seen in the 19th – Century Newspapers

open access: yesPoliteja, 2013
The beginnings of Venezuelan press were inevitably linked to national political events. This medium of expression and information has become the most expeditious vehicle to convey the modernist thought. The ideas of the Enlightenment and the Encyclopedia

Miniaturized Magnetic Tip Design for Endoluminal Vine Robot Navigation

open access: yesAdvanced Robotics Research, EarlyView.
A magnetic tip mount is designed for a miniaturized 7 mm soft‐growing vine robot to enable wireless magnetic steering and onboard imaging, while preserving a 3 mm working channel. The internal–external ring magnets design balances magnetic attachment with low eversion pressure. Experiments demonstrate ±90° steering, 34 mm bending radius, and successful
