What happens when you can get IR spectra at the nanoscale?
Dr. Derek Nowak discusses PiFM, an AFM-IR-based technique, to explain how IR spectroscopy and imaging can be extended to the nanoscale. With sub 5 nm lateral resolution and single-molecule-level sensitivity, PiFM opens up a wide variety of research avenues ranging from exploring nano-crystallin structures for drug delivery to process/failure analysis in semiconductor nanofabrication.

LIBS Illuminates the Hidden Health Risks of Indoor Welding and Soldering
April 23rd 2025A new dual-spectroscopy approach reveals real-time pollution threats in indoor workspaces. Chinese researchers have pioneered the use of laser-induced breakdown spectroscopy (LIBS) and aerosol mass spectrometry to uncover and monitor harmful heavy metal and dust emissions from soldering and welding in real-time. These complementary tools offer a fast, accurate means to evaluate air quality threats in industrial and indoor environments—where people spend most of their time.
