Storing charge in sodium-ion batteries: Study supports “three-stage” model for hard carbon anodes

In developing sodium-ion batteries, hard carbon is the material most often used for the anode, but unknowns concerning the charge storage mechanism in this material hinder further development. Researchers have proposed several models to explain the charge storage mechanism, and a recent study lends support for the three-stage “adsorption-intercalation-adsorption” process.

Video: Vitrification of human tissue

Vitrification is the process through which a material turns into a glass or glasslike substance by undergoing rapid cooling. Though the discovery this year that a man’s brain vitrified during the Mount Vesuvius eruption surprised some people, vitrification of human tissue is actually a well-established practice in fertility treatment.
