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 ...

Lower-hybrid (LH) oscillitons evolved from ion-acoustic (IA)/ion-cyclotron (IC) solitary waves: effect of electron inertia [PDF]
Nonlinear Processes in Geophysics, 2010 Lower-hybrid (LH) oscillitons reveal one aspect of geocomplexities. They have been observed by rockets and satellites in various regions in geospace. They are extraordinary solitary waves the envelop of which has a relatively longer period, while the ...

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 ...

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 ...

Effect of Varying Design Options on the Transient Behavior of a Hybrid Rocket Motor
Journal of Aerospace Technology and Management, 2014 Hybrid rockets provide compelling features for use in atmospheric and space rocket propulsion. One of the prominent applications of hybrid rockets which foster on its characteristics is the propulsion of micro air launch vehicles. In this paper, a set of

Developing Workforce Capability in the Context of HR Ecosystem Learning
Human Resource Management Journal, EarlyView.ABSTRACT For many organizations, developing workforce capabilities is central as it involves refining critical human resource processes such as upskilling or the acquisition of new profiles. These processes are becoming increasingly complex to manage as organizations collaborate within larger work ecosystems. Surprisingly, little research has addressed

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 ...
