Preventing Plasma‐Induced Resist Hardening in Molybdenum Disulfide Transistors via Sacrificial Metal Mask Lithography

open access: yesSmall, EarlyView.
Photoresist (PR) residue significantly degrades the electrical performance of 2D semiconductors such as MoS2. In particular, the intrinsically ultrathin nature of these materials makes them highly susceptible to damage during conventional PR cleaning procedures.

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 ...

The Reflexive Turn in Systems Engineering: A Disciplinary Response to Complexity

open access: yesSystems Engineering, EarlyView.
ABSTRACT The Future of Systems Engineering (FuSE) programme has called for the discipline to evolve as a transdiscipline capable of engaging complex eco‐socio‐technical challenges. Yet the pace of that evolution has been slower than the arguments for it would predict. This article examines why.

Investigation into anti-penetration analytical model of composite sandwich structure with UHMWPE laminate under high speed impact of cylindrical projectile

open access: yesZhongguo Jianchuan Yanjiu
ObjectivesIn order to quickly evaluate the ballistic performance of an ultra-high molecular weight polyethylene (UHMWPE) composite sandwich structure, a theoretical analysis model of its resistance to high-speed cylindrical projectile penetration is ...

What Is the Return on Investment of Digital Engineering for Complex Systems Development Schedules? Findings From a Mixed‐Methods Case Study on the Post‐Production Design Change Processes of Navy Assets

open access: yesSystems Engineering, EarlyView.
ABSTRACT Complex engineered systems routinely face schedule and cost overruns, along with poor post‐deployment performance. Both INCOSE and the U.S. Department of Defense (DoD) have championed Digital Engineering (DE) as a potential remedy, yet most of DE's purported benefits remain anecdotal, and its return on investment (ROI) remains poorly ...

Exploring the Landscape of MgO Polymorphs: Stability and the Electronic Band Gap of Promising Candidates

open access: yesZeitschrift für anorganische und allgemeine Chemie, EarlyView.
In this study, we have investigated possible predicted polymorphs of magnesium oxide (MgO) with respect to their thermodynamic and kinetic stability, as well as their electronic properties, focusing on the possibility of tuning the band gap of the material.

Preparing to Fight the ‘Wrong War’? Why the UK Defence Budget Must Focus More on ‘National Resilience’

open access: yesThe Political Quarterly, EarlyView.
Abstract This article argues that the current debate over defence spending in the United Kingdom is fundamentally flawed. Too much emphasis is being placed on preparing for a form of warfare with Russia that is unlikely to occur. As this article points out, the Russians actually want to avoid a traditional battlefield confrontation with NATO.

3D‐printed wound channels

open access: yesJournal of Forensic Sciences, EarlyView.
Abstract Although soft tissue simulants are widely used in ballistic research, glycerine soap is the only material that offers a clear view of the temporary cavity of a wound channel without the use of optical apparatus. However, the latter still shows some inconvenience mostly on its weight and its dehydration process when cut, making it challenging ...
