Polymer Applications with Benchtop Electron Spin Resonance

Posted by Rotunda Scientific on

Electron Spin Resonance (ESR/EPR) is a spectroscopic method that directly detects unpaired electrons—making it uniquely suited to study radicals and paramagnetic centers in polymers. These signals provide insight into oxidation, degradation, crosslinking, and polymerization pathways that other techniques cannot observe as directly. The sections below outline representative polymer applications where ESR’s radical detection power provide valuable insight. 1. Oxidative Stability and Additive Performance What it does:Radicals form as polymers degrade under heat, light, or stress, initiating chain scission and oxidation. ESR can detect these radicals—even at low levels—enabling comparison of stabilizer efficacy (e.g., HALS or antioxidants). Why it matters: Supports...

Understanding Thermoluminescence (TL) and Optically Stimulated Luminescence (OSL) in Scientific Research

Posted by Rotunda Scientific on

Understanding Thermoluminescence (TL) and Optically Stimulated Luminescence (OSL) in Scientific Research Thermoluminescence (TL) and Optically Stimulated Luminescence (OSL) are well-established analytical techniques used in geological dating, radiation dosimetry, and materials research. This article explores the physical principles behind TL and OSL, common scientific applications, and the role of modern instrumentation in supporting controlled luminescence measurements. What Are TL and OSL Techniques? Thermoluminescence (TL) and Optically Stimulated Luminescence (OSL) are methods used to measure light emitted from certain materials after exposure to ionizing radiation. These techniques are based on the behavior of trapped charge carriers within crystal lattice defects. When minerals...
