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

open access: yesSmall, 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 ...

Tailoring Microstructure and Hardness in Maraging 300 Steel via 2.4 wt.% Niobium Addition and Controlled Aging Treatments

open access: yessteel research international, EarlyView.
High Nb (2.4 wt.%) addition to Maraging 300 steel drives lattice distortion and nanoscale Nb–Mo‐rich precipitation, confirmed by energy‐dispersive X‐ray spectroscopy mapping (Mo ~5.4 wt.%, Nb ~2.5 wt.%). Nanoindentation reveals strong matrix hardening (H >4.8 GPa) at 480°C aging, while 560°C induces ~1.92 vol.% reverted austenite, enabling tunable ...

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

open access: yessteel 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 ...

Embedded Interactions and Selective Disclosure: Network Effects on Conversations aboard Skylab

open access: yesSymbolic Interaction, EarlyView.
How do absent others influence our interactions? We argue in this paper that interactions are embedded within networks formed by chains of specific relationships between known third parties. The anticipation of future interactions with external others conditions our interpretation of the current situation and affects our behavior in the interaction. We

When Time Stands Still: The Destructive Experience of Ambiguous Loss among Mothers of Combat Soldiers

open access: yesSymbolic Interaction, EarlyView.
What happens when stories refuse coherence? This article examines ambiguous loss among mothers of combat soldiers, focusing on how prolonged waiting and uncertainty infiltrate everyday life, eroding sensemaking. Drawing on ethnographic interviews, it explores how mothers experience the contraction of time and space—manifested in suspended routines ...

Defining Lines of Defense Against Change Propagation Using Cause‐Consequence Analysis

open access: yesSystems Engineering, EarlyView.
ABSTRACT Complex engineered systems are the core of modern society. So that engineered systems and infrastructure can be sustainable and offer value over the course of their lifespan, there is a growing need for such systems to be changeable. Yet, establishing and operationalizing changeability can be challenging due to the potential for change ...
