A snapshot from a molecular dynamics simulation shows the geometric order and disorder characteristics of eumelanin aggregate structures. The different variations of the eumelanin molecules are shown in different colors for clarity.
Making a paper airplane in school used to mean trouble. Today it signals a promising discovery in materials science research that could help next-generation technology -like wearable energy storage devices- get off the ground.
Scientists at Rice University have created a nanoscale detector that checks for and reports on the presence and concentration of hydrogen sulfide in crude oil and natural gas while they're still in the ground.
