Cyclo‐N9−: a Novel 5/6 Fused Polynitrogen Anion for High Energy Density Materials

open access: yesAdvanced Science, EarlyView.
This study presents a novel 5/6 fused polynitrogen anion, cyclo‐N9−, which is assembled with four cations to form energetic salts. The computational results reveal that the energy densities and detonation performances of these systems are far superior, even surpassing those of CL‐20.

Scanning of Vehicles for Nuclear Materials [PDF]

open access: yes, 2013
Might a nuclear-armed terrorist group or state use ordinary commerce to deliver a nuclear weapon by smuggling it in a cargo container or vehicle? This delivery method would be the only one available to a sub-state actor, and it might enable a state to make an unattributed attack.

Measuring Very Low Radiation Doses in PTFE for Nuclear Forensic Enrichment Reconstruction [PDF]

open access: yesarXiv, 2021
Every country that has made nuclear weapons has used uranium enrichment. Despite the centrality of this technology to international security, there is still no reliable physical marker of past enrichment that can be used to perform forensic verification of historically produced weapons.

A hegemonic nuclear order: Understanding the Ban Treaty and the power politics of nuclear weapons

open access: yesContemporary Security Policy, 2019
The notion of a “global nuclear order” has entered the lexicon of nuclear politics. The 2017 Treaty on the Prohibition of Nuclear Weapons has prompted further questions about how we understand it.

Mitigating Strain Localization via Stabilized Phase Boundaries for Strengthening Multi‐Principal Element Alloys

open access: yesAdvanced Science, EarlyView.
Strain localization along phase or grain boundaries leads to crack initiation typical of alloys. In multi‐principal element alloys, the enamel‐like microstructure is stabilized by phase boundaries. This facilitates trans‐phase migration of semi‐atomic surfaces and provides sufficient plastic space for dislocation‐mediated deformation.

Sensitivity of seismically cued antineutrino detectors to nuclear explosions [PDF]

open access: yesPhys. Rev. Applied 10, 024014 (2018), 2017
We evaluate the sensitivity of large, gadolinium-doped water detectors to antineutrinos released by nuclear fission explosions, using updated signal and background models and taking advantage of the capacity for seismic observations to provide an analysis trigger.

Targeted DNA Nanomachine Enables Specific miRNA‐Responsive Singlet Oxygen Amplification for Precise Cutaneous Squamous Cancer Therapy

open access: yesAdvanced Science, EarlyView.
An intelligent DNA nanomachine based on DNA tetrahedron is proposed, incorporated with aptamer and specific miRNA‐responsive hairpin catalytic assembly (HCA), for precise therapy of cutaneous squamous cell carcinoma (cSCC) in mice, with barely systemic toxicity and inflammation.

Contests of legitimacy and value: the Treaty on the Prohibition of Nuclear Weapons and the logic of prohibition

open access: yesInternational Affairs, 2019
The recently adopted Treaty on the Prohibition of Nuclear Weapons (TPNW) has caused much debate and controversy in global nuclear politics. Given that the stated goal of the TPNW supporters (states and NGOs alike) is to embed the treaty in the ...
