Unlocking Nanoscale Microstructural Detail in Aluminum Alloys Through Differential Phase Contrast Segmentation in STEM

Small Methods, EarlyView.
Differential phase contrast (DPC) imaging in STEM is demonstrated as a rapid, versatile segmentation tool for advanced aluminum alloys. Decomposition of false‐color DPC micrographs resolves nanoclusters, precipitate variants, dislocation strain fields, nanostructures, and grain boundaries ‐ all within a single and fast acquisition.

Perfluorohexanone for Clean Fire Suppression: Mechanisms, System Design, Applications, and Future Directions

Safety Science and Technology, EarlyView.
Driven by halon and high GWP agent phase out, perfluorohexanone is increasingly deployed in enclosures such as data centers, marine machinery spaces, and industrial process lines. This review summarizes application performance, discharge and distribution design, material compatibility, and byproduct control and maps practical gaps for large volume and ...

Fire Testing and Hazard Assessment for Flame Retardant Polymer Composites

Safety Science and Technology, EarlyView.
Flame retardant polymer composites are now being evaluated with more than pass or fail flammability tests. Heat release, smoke, toxicity, and system‐level behavior are receiving more attention, and multi‐scale methods are being used to describe fire hazard under more realistic conditions.

Assessing Capability Complexity Using Enterprise Architecture Framework

Systems Engineering, EarlyView.
ABSTRACT This study proposes a structured and quantitative methodology to evaluate the holistic complexity of system‐of‐systems (SoSs), employing the Zachman Architecture Framework (ZAF) as its foundational analytical tool. A five‐phase analytical procedure is developed and empirically validated, encompassing: (1) refinement of complexity measures, (2)

Model‐Based Systems Engineering in Space Applications: A Comprehensive Literature Review

Systems Engineering, EarlyView.
ABSTRACT The growing complexity of space engineering is driving the demand to embrace the adoption of Model‐Based Systems Engineering (MBSE). Although the MBSE is well‐practiced in the space industry, the level of effort and need required to obtain the benefits of MBSE vastly differ across enterprises; this disparity presents a significant challenge to
