Scientists from the Stanford National Accelerator (SLAC) laboratory of the US Department of Energy have revealed new information about the photoelectric effect using attosecond pulses: the delay time of photoelectric emission is as long as 700 attosecond, far exceeding previous expectations. The latest research challenges existing theoretical models and helps to reveal the interactions between ele...
Archaeologists have long wondered why the people of Anglo Saxon England began using more silver coins and fewer gold coins between 660 and 750 AD. Researchers in Europe now say they have developed a method to help find the answer. This technology combines laser ablation with traditional trace element analysis to match the isotopic abundance of silver bars in coins with known sources of metal ores ...
