On Weaponizing Cannabis

Journal of Military Ethics, 2021
Neither non-lethal violence nor psychochemical weapons are new concepts. History provides examples of attempts to use these both to limit the scope of war and to turn mind-altering compounds into weapons. One of these substances has been marijuana. Although previous efforts to find its military applications failed, the idea persists - as indicated by a

Stable microstructure in a nanocrystalline copper–tantalum alloy during shock loading

Communications Materials, 2020
Shock loading of materials alters the microstructure and considerably degrades mechanical performance. Here, shock loading of a nanocrystalline Cu–Ta alloy is found to induce minor changes to microstructure and mechanical performance, attributed to the ...

Dynamic characteristics of Mn-Cu high damping alloy subjected to impact load

Advances in Mechanical Engineering, 2021
Mn-Cu high damping alloy is a twin-type damping alloy. Owing to its martensite twin structure at room temperature, it can convert vibration energy into heat energy, thereby reducing vibration.
