Self-calibration strategies for reducing systematic slope measurement errors of autocollimators in deflectometric profilometry

Journal of Synchrotron Radiation
Deflectometric profilometers are used to precisely measure the form of beam shaping optics of synchrotrons and X-ray free-electron lasers. They often utilize autocollimators which measure slope by evaluating the displacement of a reticle image on a ...

Corrosion Inhibition of S275 Carbon Steel in CO2 Capture Systems Using Monoethanolamine (MEA) Solvent

Materials and Corrosion, EarlyView.
Corrosion inhibitors CuSO4 and NaVO3 achieved up to 98% inhibition efficiency for carbon steel S275 in CO2‐loaded MEA solvent, reducing corrosion rates to 9.4 µm/year—outperforming costly stainless steel SS 316 L at a fraction of the cost. ABSTRACT Corrosion in CO2 capture units significantly impacts safety and costs.
