Small‐Scale Magnetic Soft Robots for Medical Applications: From Laboratory to Clinical Use

SmartBot, EarlyView.
Small‐scale magnetic soft robots are emerging as promising platforms for minimally invasive diagnosis and therapy in complex in vivo environments. This review compares untethered and tethered medical magnetic robots in parallel across five translational stages, from basic performance testing to clinical evaluation.

Strategy for One‐Step Optimization of Metal Oxide Passivating Contact Materials for Si Heterojunction Solar Cells through Growth Angle Variation

Small, EarlyView.
A one‐step oblique angle reactive sputtering approach enables simultaneous tuning of bulk and interfacial stoichiometry in a metal oxide/ silicon heterojunction. In case of vanadium oxides, growth angle variation controls the formation of stoichiometric SiO2, ternary SiOx(V) interlayer, and phase purity of vanadium oxide, considerably simplifying the ...

The development and implementation of a hybrid rocket motor thrust stand to investigate the relationship between combustion chamber pressure and graphite rocket nozzle erosion in hybrid rocket motors

, 2022
Rocket motors frequently implement carbon-based nozzle inserts to insulate the motor from the heat produced by combustion. Over time these inserts will erode due to oxidation at the surface wherein oxidizing species found in the combustion products react with the carbon to form carbon monoxide.

Crash Behavior of DP800–DP1000 Advanced High‐Strength Steel’s Dissimilar Resistance Spot Welded Joints Under Quasi‐static and High Strain Rates

steel research international, EarlyView.
The high‐strain‐rate behavior of resistance spot‐welded DP800–DP1000 joints is investigated. Results show that microstructural gradients across BM–HAZ–FZ govern hardness, strain rate sensitivity, and failure modes. While strength increases with strain rate, energy absorption is controlled by ductility, with DP800–DP800 joints showing superior ...

Sino‐Mexican Encounters Before the ‘Diplomatic Opening’: Exhibition Diplomacy and Grassroots Friendship in the 1960s

History, EarlyView.
Abstract During the 1960s, Mexico's Institutional Revolutionary Party (PRI) embraced Chinese overtures for a commercial opening as consistent with its anti‐imperialist posture, thereby foreshadowing the diplomatic opening to China in 1972. Yet this professed ideological pluralism was eclipsed by an underlying allegiance to the United States' anti ...

HYBRID ROCKET ENGINE TEST FACILITY DESIGN

Havacılık ve Uzay Teknolojileri Dergisi, 2016
Hybrid rocket engines is relatively less researched subject of chemical rockets. Using fuel and oxidizer in different phases hybrids are safe and cheap. Yet, they are not generating enogh thrust to deliver heavy payloads to edge of space.

DIFFERENTIATED INFRASTRUCTURAL CITIZENSHIP: Claims‐Making and the Limits to Transformative Urbanization in a Fast‐Growing Small City

International Journal of Urban and Regional Research, EarlyView.
Abstract This article develops the concept of differentiated infrastructural citizenship (DIC) to explain how infrastructural citizenship is materially mediated, socially differentiated, and unevenly exercised in a rapidly urbanizing small city. It advances scholarship on infrastructural citizenship and everyday claims‐making as political participation

The Mysterious Stranger and Modern Enchantment

The British Journal of Sociology, EarlyView.
ABSTRACT Sociological accounts of modernity have long emphasized rationalization, alienation, and the attenuation of affective intensity. While these diagnoses capture crucial dynamics of modern social order, they leave underexplored a persistent and generative dimension of social life: enchantment.

Multiplying Elements of Fragmentation? Polycentrism, the Launcher Crisis and the Future of Europe in Space

Global Policy, EarlyView.
ABSTRACT This article explores the current controversies surrounding the European Ariane launcher and its implications for the future of European space governance. The Ariane program, historically a symbol of European technopolitical integration, faces mounting challenges due to delays, rising costs and increasing competition from private actors like ...

Re‐thinking peripheral dysfunctions in obesity: The emerging role of sulphaceutics and sulphanutraceutics

British Journal of Pharmacology, EarlyView.
Obesity is a chronic, relapsing, multisystem disease in which cardiometabolic risk arises from excess adiposity and progressive dysfunction of peripheral organs, ultimately disrupting endocrine and metabolic crosstalk among tissues. Within this network, sulphur‐based biology, centred on hydrogen sulphide and related reactive sulphur species, has ...
