Dead batteries could soon find a second lease on life thanks to a new chemical injection. One of the problems with lithium-ion batteries is that, over time, they slowly lose their charging efficacy, ...

One September day, it started to snow inside MIT's Pierce Laboratory. Researchers depressurized a tank of liquid carbon dioxide (CO2), instantly freezing it and releasing solid flakes. These were ...

A chemical injection can restore spent lithium-ion batteries to working order again. The one-step process could reduce waste and boost the supply of batteries needed for fleets of electric vehicles.

Background: Lethal injection for execution was conceived as a comparatively humane alternative to electrocution or cyanide gas. The current protocols are based on one improvised by a medical examiner ...

An improved electroosmotic method is proposed in this paper to enhance the non-uniform effect and efficiency of electroosmotic process. Such method is electroosmotic flow with injection of calcium ...

Most US executions are beset by procedural problems that could lead to insufficient anesthesia in executions. This hypothesis has been supported by findings of low postmortem blood thiopental levels ...
