Light‐Promoted Hydrazine Dehydrogenation over Ni/NH2‐MIL‐125: Unraveling Mechanisms for Efficient Hydrogen Production

open access: yesAdvanced Science, Volume 13, Issue 11, 23 February 2026.
Highly dispersed and electron‐rich Ni nanoparticles (≈2.7 nm) supported on NH2‐MIL‐125 significantly promote the dehydrogenation of hydrous hydrazine under visible‐light irradiation, achieving a turnover frequency of 220.2 h−1 at 323 K, which is more than twice that in the dark (108.1 h−1) and outperforms most reported non‐precious metal catalysts ...

Private Network Realignment: State Strategies Versus Market‐Driven Globalization in the Subsea Cable Network

open access: yesGlobal Policy, Volume 17, Issue 1, Page 94-106, February 2026.
ABSTRACT Much of the subsea cable network, which carries the vast majority of global internet traffic, is developed, owned, and operated by private corporations. In an era of growing global tensions, states have come to view these cables as critical to their interests. The article addresses the disconnect between statecraft‐centric explanations and the

UNDERSEA: An Exemplar for Engineering Self-Adaptive Unmanned Underwater Vehicles (Artifact).

open access: yesDagstuhl Artifacts Ser., 2017
Recent advances in embedded systems and underwater communications raised the autonomy levels in unmanned underwater vehicles (UUVs) from human-driven and scripted to adaptive and self-managing. UUVs can execute longer and more challenging missions, and include functionality that enables adaptation to unexpected oceanic or vehicle changes.

Weaponising the Supply Chain: Yemen's Blockade and the Contradictions of Maritime Logistics Capital

open access: yesAntipode, Volume 58, Issue 1, January 2026.
Abstract This paper examines the 2023–2025 naval blockade imposed by Yemen in the Red Sea. It argues that the blockade's success in disrupting global trade stemmed from the potent confluence of asymmetric military tactics and the structural vulnerabilities inherent within global maritime logistics capitalism.

Haptic Interface for Center of Workspace Interaction [PDF]

open access: yes, 2002
We build upon a new interaction style for 3D interfaces, called the center of workspace interaction. This style of interaction is defined with respect to a central fixed point in 3D space, conceptually within arm\u27s length of the user.
