Picogram-Level Nanoplastic Analysis with Nanoelectromechanical System Fourier Transform Infrared Spectroscopy: NEMS-FTIR
Jelena Timarac-PopoviÄ, Johannes Hiesberger, Eldira Å esto +5
We present a photothermal infrared spectroscopy-based approach for the chemical characterization and quantification of nanoplastics. By combining the high sensitivity of nanoelectr…
Optimal Sensing of Momentum Kicks with a Feedback-Controlled Nanomechanical Resonator
Kaspar Schmerling, Hajrudin BeÅ¡iÄ, Andreas Kugi +2
External disturbances exciting a mechanical resonator can be exploited to gain information on the environment. Many of these interactions manifest as momentum kicks, such as the re…
Optimized Signal Estimation in Nanomechanical Photothermal Sensing via Thermal Response Modelling and Kalman Filtering
Hajrudin BeÅ¡iÄ, Andreas Deutschmann-Olek, Kenan MeÅ¡iÄ +2
We present an advanced thermal response model for micro- and nanomechanical systems in photothermal sensing, designed to balance speed and precision. Our model considers the two ti…
