Are there multiple versions of the dataset? no -------------------------- METHODOLOGICAL INFORMATION -------------------------- 1. Description of methods used for collection/generation of data: A. Cryogenic transmission electron microscopy (cryo-TEM): Samples were vitrified using an FEI Vitrobot Mark IV set to 60 °C and 100% relative humidity. For the vitrification process, the sample was applied to a lacey formvar−carbon-coated copper TEM grids (Structure Probe, Inc.). The grid was blotted to remove excess gel with a blot time of 1 s, a hold time of 1 s, and a blot force (the dimensionless instrument parameter for controlling the blotting pressure) of −1. Samples were plunge-frozen into liquid ethane and stored in liquid nitrogen. Samples were transferred under liquid nitrogen to a Gatan 626 single-tilt cryo-stage. Imaging was conducted on an FEI Tecnai Spirit BioTwin microscope. B. Phase-Plate Cryo-TEM: Cryo-TEM specimens were prepared in a controlled environment vitrification system at 60 °C and 100% relative humidity (https://onlinelibrary.wiley.com/doi/abs/10.1002/jemt.1060100111). The specimens were blotted manually and plunged into liquid ethane at its freezing point. The cryo-specimens were loaded into a Gatan 626 cryo-holder and kept in an FEI Talos 200C high-resolution TEM equipped with a Schottky field-emission gun at −180 °C. The image contrast was enhanced by a Volta “phase-plate” that converts image phase differences into amplitude difference (https://www.jstage.jst.go.jp/article/biophysics/2/0/2_0_35/_article). Images were recorded at an acceleration voltage of 200 kV by an FEI Falcon III direct-imaging camera, using very low electron exposure, below 10 e−/Å2. C. Small-angle X-ray scattering (SAXS): Experiments were conducted at the DND-CAT, Sector 5-ID-D of the Advanced Photon Source at Argonne National Laboratory. Two-dimensional (2D) scattering patterns were collected during 1 s exposures to 0.0729 nm wavelength X-rays on a Rayonix MX170-HS CCD detector, at a sample-to- detector distance of 8.5 m. The detector readout was binned to 4 × 4 pixels to decrease the detector readout noise. The 2D SAXS data were integrated azimuthally yielding one-dimensional (1D) scattering patterns of intensity versus the scattering wave vector q. At the X-ray wavelength and detector distance used, the q range accessed was 2.35 × 10−3 to 0.137 Å−1. Samples were prepared by loading 1 wt% solutions into 1.5 mm diameter quartz capillaries, which were subsequently sealed with epoxy and placed into a custom-fabricated eight-capillary heating stage. Each set of eight samples was heated stepwise by 10 °C for 10 min to approximate a 1 °C/min temperature ramp. D. Mid- and wide-angle X-ray scattering (MAXS and WAXS): Experiments were conducted at the DND-CAT, Sector 5-ID-D of the Advanced Photon Source at Argonne National Laboratory. 0.001 in. thick films were secured in a nylon washer by Kapton tape and placed in the path of the beam. 2D data were collected with a 1 s exposure with a SAXS, MAXS, and WAXS detector simultaneously. The 2D data were integrated azimuthally yielding one-dimensional (1D) scattering patterns of intensity versus the scattering wave vector q. Rayonix LX170-HS CCD detectors were employed for the MAXS and WAXS measurements at sample-to-detector distances of 1.01 and 0.2 m, respectively, and were generally binned at 2 × 2 pixels. The q values accessed for these detectors were from q = 0.13 to 0.86 Å−1 for MAXS and 0.68−4.5 Å−1 for WAXS. 2. Methods for processing the data: A. Cryo-TEM images were processed using Image-J software. B. 1D SAXS patterns were analyzed using SASView (Small-Angle Scattering Analysis Software Package) developed at NIST. A power law background was subtracted from each sample to account (approximately) for water and quartz scattering. A form factor for a semiflexible cylinder with a disperse radius was used to fit the SAXS patterns (https://pubs.acs.org/doi/abs/10.1021/ma9607630?src=recsys; https://pubmed.ncbi.nlm.nih.gov/16830995/). The scattering length density and scale terms (volume fraction of polymer, φ, multiplied by the fibril volume) were combined into a single fitting term, A_scale. Because of the lower limit of q (0.00235 Å−1), the fibril length and Kuhn length were fixed at 500 μm and 50 nm, respectively. The values were estimated from previous work regarding the length of MC fibrils.19 The radius dispersity was held at 0.30, based on a Schulz−Zimm distribution of radii, to reduce the number of free parameters.
