title: Large SEM-BSE images of hydrated alite of ages from 1 day up to 1 year

description: This dataset contains 8-Bit SEM-BSE images of commercially available tricalcium silicate (C<sub>3</sub>S; alite, MIII polymorph; Vustah, Czech Republic). The alite was mixed with a water/binder ratio of 0.5. The paste was the cast in small sealed containers, which were submersed with water. The specimens were stored at 22 ± 2°C. After the desired hydration times (1, 7, 14, 28, 84, 365 days) the hydration was stopped by immersing the prisms in isopropanol and drying them at 60°C for 12 hours. The dried prisms were then embedded in low viscosity epoxy resin and mechanically polished using diamond paste with a grain size down to 0.25 µm. Finally, the specimens were coatet with a thin layer of carbon to avoid charging. The images were acquired at 10 kV (7d), 12 kV (14-365d) and 15 kV (1d) using a CBS (concentric backscatter, 14-365d) and a ABS (1 and 7d) detector within a Thermofischer Helios G4 UX. <strong>Table 1</strong>: Basic information like resolution, size and phase composition of the images. <strong>file</strong> <strong>age</strong> <strong>size</strong> <strong>size</strong> <strong>area</strong> <strong>pores</strong> <strong>hydrates</strong> <strong>clinker</strong> in days in px in µm in mm² area-% area-% area-% C3S 1d.tif 1 21179 x 21495 749.9 x 749.9 0.56 38.5 38 23.9 C3S 7d.tif 7 19433 x 19320 390.9 x 390.9 0.15 32.2 48.5 19.4 C3S 14d.tif 14 36864 x 36864 1554.0 x 1554.0 2.41 22.2 44.5 33.6 C3S 28d.tif 28 36864 x 36864 1554.0 x 1554.0 2.41 16.9 74.9 8.3 C3S 84d.tif 84 36864 x 36864 1554.0 x 1554.0 2.41 21.7 72.7 5.7 C3S 365d.tif 365 36864 x 36864 1554.0 x 1554.0 2.41 14.8 83.2 2.0 The proportions of pores, hydrates and unhydrated clinker shown in table 1 are the result of manual thresholding of denoised versions of these images and may therefore differ to own measurements.

title: Supplementary Material for: Late lesion growth following endovascular therapy: is 24 hours too early to assess acute infarct size including the effects of secondary injury?

description: Introduction
Stroke lesion volume on MRI or CT provides objective evidence of tissue injury as a consequence of ischemic stroke. Measurement of “final” lesion volume at 24hr following endovascular therapy (post-EVT) has been used in multiple studies as a surrogate for clinical outcome. However, despite successful recanalization, a significant proportion of patients do not experience favorable clinical outcome. The goals of this study were to quantify lesion growth during the first week after treatment, identify early predictors, and explore the association with clinical outcome.
Methods
This is a prospective study of stroke patients at two centers who met the following criteria: i) anterior large vessel occlusion (LVO) acute ischemic stroke, ii) attempted EVT, and iii) had 3T MRI post-EVT at 24hr and 5-day. We defined “Early” and “Late” lesion growth as ≥10mL lesion growth between baseline and 24hr DWI, and between 24hr DWI and 5-day FLAIR, respectively. Complete reperfusion was defined as &gt;90% reduction of the volume of tissue with perfusion delay (Tmax&gt;6sec) between pre-EVT and 24hr post-EVT. Favorable clinical outcome was defined as modified Rankin scale (mRS) of 0-2 at 30 or 90 days.
Results
One hundred twelve patients met study criteria with median age 67 years, 56% female, median admit NIHSS 19, 54% received IV or IA thrombolysis, 66% with M1 occlusion, and median baseline DWI volume 21.2mL. Successful recanalization was achieved in 87% and 68% had complete reperfusion, with an overall favorable clinical outcome rate of 53%. Nearly two thirds (65%) of the patients did not have Late lesion growth with a median volume change of -0.3mL between 24hr and 5-days and an associated high rate of favorable clinical outcome (64%). However, ~1/3 of patients (35%) did have significant Late lesion growth despite successful recanalization (87%: 46% mTICI 2b/ 41% mTICI 3). Late lesion growth patients had a 27.4mL change in Late lesion volume and 30.1mL change in Early lesion volume. These patients had an increased hemorrhagic transformation rate of 68% with only 1 in 3 patients having favorable clinical outcome. Late lesion growth was independently associated with incomplete reperfusion, hemorrhagic transformation, and unfavorable outcome.
Conclusion
Approximately 1 out of 3 patients had Late lesion growth following EVT, with a favorable clinical outcome occurring in only 1 out of 3 of these patients. Most patients with no Early lesion growth had no Late lesion growth. Identification of patients with Late lesion growth could be critical to guide clinical management and inform prognosis post-EVT. Additionally, it can serve as an imaging biomarker for the development of adjunctive therapies to mitigate reperfusion injury.

title: Synthesis of Chiral Pyrene-Based 1,4-Dithiins [Data]

description: The 1,4-dithiin motif is known for its reversible redox properties to generate radical cations and diradical dications and thus is interesting for organic electronic applications. However, examples where this motif is embedded into chiral larger fused aromatic compounds is very rare. Here we describe the syntheses of several structurally related pyrene fused dithiins and their spectroscopic investigations with a focus on tuning circular dichroism in respect the g values depending on their connectivity.

title: Chirale polyzyklische aromatische Kohlenwasserstoffe mit Affensattel-Topologie [Data]

description: In this thesis, the first chiral polycyclic aromatic hydrocarbon (PAH) with a monkey saddle topology is presented. Starting from a truxene building block that is readily preparatively accessible, the monkey saddle PAH could easily be obtained in three steps. By using additional functionalized precursors, a series of twelve derivatives has been obtained and characterized. Solid-state structures confirmed the three-dimensional shape of the PAHs unambiguously, which is induced by the five-, six- and eight-membered rings. This makes the PAH a section of a Mackay-type crystal. Due to the curvature, the target compounds exhibit triple axial chirality. Separation of the enantiomers was possible and characterization of these via CD spectroscopy and the investigation of racemization revealed half-lives ranging from a few milliseconds to several days. In addition, first attempts to synthesize Mackay-like cage compounds have been conducted and provided important insights for future projects. A deeper insight into the properties of the curved PAHs was achieved by the isosteric exchange of three CH groups with nitrogen. Its effect could be studied in detail and led to a stabilization of the enantiomers towards a half-life of two months. Furthermore, a rearrangement was developed that lead to a chiral molecular basket whose enantiomers do not longer racemize at room temperature. The experimental results were supported and extended by a large number of quantumchemical calculations. A second truxene precursor formed the basis on which the preparation of a system with three azulene units succeeded. Synthetic difficulties on the way to the target compound could be circumvented and thus a keto-functionalized PAH has been obtained, which forms two separable diastereomers. The azulene PAH represents a model of a graphene defect due to the five- and seven-membered rings and was studied in terms of its photophysical and electrochemical properties as well as compared with isomeric compounds. Confirmation of the structures of all three target compounds by X-ray structural analysis was also successful. First experiments on post-functionalization were performed so that future projects can build on them.

description: Among graphene nanoribbons (GNRs), reports on coronene-based GNRs were very rare, despite the unique optoelectronic properties of coronene. Herein, the synthesis of a series of structurally precise and soluble thieno-fused coronene nanoribbons (CR-1 to CR-4) with up to four coronene units connected through benzene rings along their K-regions is described by two different synthetic approaches. Due to the triptycene end-caps all CRs are highly soluble, allowing to characterize such structures in solution and study the length dependent photophysical properties which are supported by theoretical calculations.
