Radio Frequency Glow Discharge Optical Emission Spectroscopy: Depth Profiling Analysis of Thin Anodic Alumina Films as Potential Reference Materials (PDF)
The need for reference materials that can be applied in the area of thin films analysis has long been realized but is still, in general, under-addressed. Alumina films of single-micrometer thickness, having either fine distributions of impurities or delta function impurity marker layers, can be prepared routinely by anodic oxidation of electropolished aluminum specimens in appropriate electrolytes. Selected films were examined by transmission electron microscopy (TEM) and analyzed by radio frequency glow discharge optical emission spectroscopy (rf-GD-OES), providing very rapid, yet high-resolution, depth-resolved analysis of these electrically insulating materials.

Wednesday's program at SciX 2026 kept returning to one question: can spectroscopy perform outside the controlled laboratory? Speakers took surface-enhanced Raman scattering (SERS), laser-induced breakdown spectroscopy (LIBS), mid-infrared photonics, chemometrics, and fluorescence excitation–emission matrix (EEM) spectroscopy into clinics, food plants, reactor coolant loops, brine fields, and drinking water supplies.
As part of our coverage of the SciX 2026 Conference, Nancy Pleshko and Petra Baylin of Temple University sat down with Spectroscopy to talk about their recent study, explaining how Fourier transform infrared (FT-IR) imaging of ultra-high weight molecular polyethylene (UHMWPE) implants permits oxidation evaluation throughout the sample yielding insight into failure.
