via ScienceDaily, 21 August 2018: Not about Southeast Asia, but of interest to underwater archaeologists. A possible way to preserve wood recovered from underwater contexts through the use of smart nanocomposite particles.
When a shipwreck is brought up from the sea depths, the wood quickly starts deteriorating. Scientists are reporting a novel way to use ‘smart’ nanocomposites to conserve a 16th-century British warship, the Mary Rose, and its artifacts. The new approach could help preserve other salvaged ships by eliminating harmful acids without damaging the wooden structures themselves.
