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.

Electron Captures on $^{14}{\rm N}$ as a Trigger for Helium Shell Detonations [PDF]

open access: yes, 2017
White dwarfs (WDs) that accrete helium at rates $\sim 10^{-8} \, M_\odot \, \rm yr^{-1}$, such as those in close binaries with sdB stars, can accumulate large ($\gtrsim 0.1 \, M_\odot$) helium envelopes which are likely to detonate. We perform binary stellar evolution calculations of sdB+WD binary systems with MESA, incorporating the important reaction

High-Voltage Ignition Circuit For Compressed Natural Gas Direct Injection Engine [PDF]

open access: yes, 2007
Ignition system of an internal combustion engine is an important part of the overall engine management system. It is a means to provide enough high-voltage, minimum around 20 kV to form an arc across the gap of a spark plug and to control the ignition ...

A Methionine Allocation Nanoregulator for the Suppression of Cancer Stem Cells and Support to the Immune Cells by Epigenetic Regulation

open access: yesAdvanced Science, EarlyView.
A nanoregulator interfering with intratumoral methionine competition is designed to deliver oxaliplatin (IV) prodrugs and anti‐Lat4 small interfering RNA to tumor cells. This Pt (IV)‐crosslinked reduction‐sensitive nanoregulator progressively releases drugs within tumor cells and induces immunogenic cell death.

Tetrahedral Nitrogen Atoms Arrangement in A‐Site Cations: A New Approach for Regulating Sensitivity and Energy of Perovskite Energetic Materials

open access: yesAdvanced Science, EarlyView.
The urotropine is selected as the A‐site cation in PEMs, and four urotropine‐based PEMs ([C6H14N4][M(ClO4)3]) are successfully prepared. Compared with the cubic PEMs, the crystal structure of the urotropine‐based PEMs has an expansion along the c‐axis.

Ignition of sounding rocket motors with hand-pumped air [PDF]

open access: yes, 1974
Method demonstrates inexpensive, safe, and foolproof concept for solid propellant rocket motors, using simple handpump to deliver air. Flueric ignition was accomplished using system without stored energy and with complete absence of electrical energy and
