Multifunctional Silver‐Exchanged Zeolite Micromotors for Catalytic Detoxification of Chemical and Biological Threats

Multifunctional reactive‐zeolite‐based micromotors have been developed and characterized toward effective and rapid elimination of chemical and biological threats. The incorporation of silver ions (Ag⁺) into aluminosilicate zeolite framework imparts several attractive functions, including strong binding to chemical warfare agents (CWA) followed by effective degradation, and enhanced antibacterial activity. The new zeolite‐micromotors protocol thus combines the remarkable adsorption capacity of zeolites and the efficient catalytic properties of the reactive Ag⁺ ions with the autonomous movement of the zeolite micromotors for an accelerated detoxification of CWA. Furthermore, the high antibacterial activity of Ag⁺ along with the rapid micromotor movement enhances the contact between bacteria and reactive Ag⁺, leading to a powerful “on‐the‐fly” bacteria killing capacity. These attractive adsorptive/catalytic features of the self‐propelled zeolite micromotors eliminate secondary environmental contamination compared to adsorptive micromotors. The distinct cubic geometry of the zeolite micromotors leads to enhanced bubble generation and faster movement, in unique movement trajectories, which increases the fluid convection and highly efficient detoxification of CWA and killing of bacteria. The attractive capabilities of these zeolite micromotors will pave the way for their diverse applications in defense, environmental and biomedical applications in more economical and sustainable manner.     

Consideration of the use of autonomous,non-recallable unmanned vehicles and programs as a deterrent or threat by state actors and others

This paper considers the use of a non-recallable control technology (either for craft control or to command weaponized software) as a deterrent or threat mechanism by state and non-state actors. It considers the efficacy of this approach in modern war fighting (including in limited war-like scenarios), comparing it to the mutual assured destruction phenomenon created by atomic weaponry and the Zanryū Nipponhei (‘Japanese holdout’) scenario. The deterrent, immediate and long-term impacts of the non-recallable control technology are considered from a warfighting perspective. The ethical and societal implications of the development of this technology and the proverbial opening of Pandora's Box that its development represents are also considered.
