Archaeologists recently discovered ammunition including a 210-millimeter shell from the wreckage of a ship sunk in the First Sino-Japanese War (1894-95) during the Qing Dynasty (1644-1911).
Researchers have created a material that is able to prevent liquids and gases from penetrating the material and protect vital components. While flexible batteries are one potential application for this new wonder material, the team claims that other devices using liquids or showing sensitivity to oxygen exposure will benefit from this using the new technology.
A method has been developed by an international team of researchers that uses liquid metal to produce an elastic material that is virtually immune to both gases and liquids.
