In a recent study published in the journal AIP Advances, researchers used molecular and elemental spectroscopy techniques such as laser induced breakdown spectroscopy (LIBS), Raman spectroscopy, and Fourier transform infrared (FT-IR) spectroscopy to characterize mines in ancient Egypt.In this study, researchers examined various gemstones that can be traced back to the era of the pharaohs. The team...
Recently, Italian startup Lithium Lasers announced that the company has successfully raised 3.5 million euros in ultra short pulse laser technology.This company, founded in 2019, focuses on developing an ultra short pulse laser (USPL) called FemtoFlash, which is aimed at multiple industries such as aerospace, healthcare, automotive, and consumer electronics, particularly suitable for material proc...
When observing biological samples under a microscope, if the medium in which the objective lens is located is different from the sample, the light beam will be interfered with. For example, when observing a water sample with a lens surrounded by air, the light bends more strongly in the air around the lens than in water.This interference can cause the measured sample depth to be smaller than the a...
Researchers from Shantou University have reported a review of residual stresses in metal additive manufacturing: detection techniques, numerical simulations, and mitigation strategies. The relevant paper titled "A comprehensive review of residual stress in metal additive manufacturing: detection techniques, numerical simulations, and mitigation strategies" was published in the Journal of the Brazi...
