Sustainable Development, EarlyView.ABSTRACT Farmers' capabilities, a core component of social sustainability, have been largely neglected in sustainable agriculture discourse. Using a relational approach to capabilities and autonomy, this study explores how women farmers translate the opportunity of agricultural innovation into their valued outcomes, and which factors shape their ...

Surface and Interface Analysis, EarlyView.ABSTRACT In the present study, we have analyzed the growth profile of ruthenium (Ru) thin films, deposited using pulsed direct current (DC) magnetron sputtering technique, by varying the sputtering voltages in the range of 150–420 V. The grazing incidence X‐ray reflectivity (GIXRR), time‐of‐flight secondary ion mass spectrometry (ToF‐SIMS), and atomic ...

Electrets used to measure exhaust cloud effluents from Solid Rocket Motor (SRM) during demonstration model (DM-2) static test firing [PDF]
Electrets were compared with fixed flow samplers during static test firing. The measurement of the rocket exhaust effluents by samplers and electrets indicated that the Solid Rocket Motor had no significant effect on the air quality in the area sampled ...

Sampling, Mobility, and Anchoring in Small‐Body Sampling Robots: A Comprehensive Review
SmartBot, EarlyView.Small‐body sampling robots are exploration systems that perform contact, sampling, and stable operations on microgravity bodies such as asteroids and comets. The authors review representative robot architectures and key technologies, focusing on the mechanisms, evolution, and coupling of sampling, mobility, and anchoring.

Resource redeployment as an entry advantage in resource‐poor settings
Strategic Management Journal, EarlyView.Abstract Research Summary Scarcity of productive factors poses a challenge for firms entering underdeveloped regions. We theorize that incumbent firms can overcome scarcity of skilled human capital in local labor markets by redeploying workers from existing units.

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 ...

steel research international, EarlyView.Cold spray deposition of stainless steel (grade: SS304) is evaluated for marine applications, with emphasis on martensitic transformation during impact. Analytical modeling, simulations, and experiments reveal that helium‐assisted spraying of fine powders promotes cooling below the martensitic start temperature, enabling up to ≈40% austenite to ...
