Erratum: Correlating the Morphological Evolution of Individual Catalyst Particles to the Kinetic Behavior of Metallocene-Based Ethylene Polymerization Catalysts (JACS Au (2021) 1:11 (1996−2008) DOI: 10.1021/jacsau.1c0032410.1021/jacsau.1c00324)

Figure 1 in the original paper shows d-acetonitrile molecules with four bonds between the N and C atoms. This has been corrected here. new figure to demonstrate a direct correlation between the point spectra and IR maps that were recorded on the given particle cross-section. The main text was adapted as follows: Point spectra, recorded of PE- (i.e., A1 and B1 in Figure 5) and silica-rich regions (i.e., A2 and B2 in Figure 5) as well as reference materials (Figures S10.S12), further helped to assign the imaged phases. A correction to the Supporting Information, section S4.B, was made to reflect that all data were recorded in PiF and not PiFM mode: Atomic force microscopy (AFM) topography images, IR maps and IR point spectra were recorded in dynamic noncontact PiF mode (60 accumulations, 500 ms pixel dwell time, 1 cm.1 spectral resolution) using NCHR Au-coated cantilevers (force constant: 40 N/m). The iFM labels in Figures S7.S9 (Supporting Information) were changed to PiF. Furthermore, the methodology for recording an IR map at a specific wavenumber was described in more detail, both in the Supporting Information and in the main text: Prior to acquiring an IR map at a specific wavenumber, a preliminary low-resolution scan was performed. A point spectrum was then taken in the mapped area to determine the wavenumber of the targeted vibrational band (i.e., the wavenumber at which the band has its maximum intensity). The IR PiFM maps were recorded in noncontact mode26 (amplitude ratio set point of 80%, attractive van der Waals force regime; Table S3) at characteristic wavenumbers for the Si.O stretching vibration46,47 (maps recorded at single wavenumbers in the range of 1050.1030 cm.1, (Si.O), Figure 4) and the symmetric C.H bending vibration of the methylene group37.39 (maps recorded at single wavenumbers in the range of 1472.1460 cm-1, (C.H), Figure 4).
