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 ...
A team of computer and electrical engineers at UC Santa Barbara, in collaboration with several colleagues at Caltech and another colleague at Anello Photonics, has developed a first-of-its-kind chip that can carry both laser and photonic waveguides. In a paper published in the journal Nature, the team describes how they made the chip and how it worked during testing.With the advent of integrated c...
Laser gas analysis can achieve high sensitivity and selectivity in gas detection. The multi-component capability and wide dynamic range of this detection method help analyze gas mixtures with a wide concentration range. Due to the fact that this method does not require sample preparation or pre concentration, it is easy to adopt in the laboratory or industry.Gas analysis is crucial for determining...
