Controlled Formation of Carbon Nanotubes and Nanotube Junctions from Bilayer Graphene
Small, EarlyView.Twisted bilayer graphene is cut using a scanning transmission electron microscope to create individual chiral carbon nanotubes and interconnected nanotube junctions. The sculpting is facilitated by in situ heating and automated beam control. Bilayer graphene ribbons with a width of less than approximately 4 nm spontaneously convert to CNTs, while no ...

Activatable smart contrast agents for photoacoustic imaging
Smart Molecules, EarlyView.This review highlights recent advances in smart activatable photoacoustic imaging (PAI) contrast agents, which dynamically modulate their optical properties in response to external stimuli or microenvironmental cues. It discusses their molecular design, activation mechanisms, biomedical applications, and future prospects for clinically tailored use ...

The Unintended Consequences of German Deterrence
Global Policy, EarlyView.ABSTRACT Germany's evolving deterrence posture boils down to continued participation in NATO nuclear sharing and an ambitious conventional rearmament program. Due to its non‐nuclear status and a result of decades of underinvestment, Germany prioritizes modern conventional weapons.

A remotely operated blood sampling and sedative administration device in freely moving pinnipeds
Methods in Ecology and Evolution, EarlyView.Abstract A remotely operated device for use with freely moving pinnipeds was designed and successfully developed for the collection of blood samples and the administration of sedatives via an indwelling, venous catheter. The performance of the sampler, called the ‘Mossquito’, was demonstrated on six wild caught, young‐of‐the‐year grey seals ...

American Journal of Political Science, EarlyView.Abstract How can defense alliances reap the efficiency gains of working together when coordination and opportunism costs are high? Although specializing as part of a collective comes with economic and functional benefits, states must bargain over the distribution of those gains and ensure the costs of collective action are minimized.
