Spectroscopy Strikes Gold
A handful of non-destructive spectroscopic techniques have authenticated a collection of Roman coins – validating the existence of a “new” emperor, called Sponsian. The team, led by Paul Pearson, University College London, proposed a new hypothesis: “Sponsian ruled Roman Dacia, an isolated gold mining outpost, in 260 CE, at a time when the empire was beset by civil wars and the borderlands were overrun by plundering invaders.” Read more! |
Hot new technique
The first triage of a burn injury is crucial in forming successful clinical treatment plans. However, accuracy rates of burn depth evaluation are currently around 60-75 percent, suggesting that the most appropriate treatment is not always given. With this in mind, researchers from Stony Brook University, New York, USA, have employed a neural network model that uses terahertz time-domain spectroscopy (THz-TDS) to non-invasively triage burns. The new technique was combined with a handheld imaging device, named PHASR, to rapidly image in vivo burn injuries using THz-TDS. Results showed an average accuracy rate of 84.5 percent when estimating burn severity, and predicted the outcome of the wound healing process with an accuracy rate of 93 percent. Researchers hope that – with further testing – the handheld device may be integrated into point-of-care settings for clinical burn assessment. |
