A model non-graphitizable carbon - sucrose char and two commercial carbon blacks of varied nanostructure have been used to study crystallinity improvements at two oxidative burnout levels. The virgin materials have been compared to their partially oxidized counterparts at a series of heat treatment temperatures using X-ray diffraction for bulk crys-tallinity analysis and high-resolution transmission electron microscopy for nanostructural characterization. Remarkable improvements were observed in the case of sucrose char where non-graphitizable sponge-like particles transformed into highly ordered graphenic flakes by the mechanism of oxidative liberation of crosslinks. The in-plane crystallite size and stacking height tripled after the liberation of the restrictive crosslinks. Molecular level changes after partial oxidation have been assessed using Raman spectroscopy while X-ray photoelectron spectroscopy is used to assess changes in elemental composition. Notable improvements were also observed in carbon blacks with the development of longer and lower tortuosity lamellae accompanied by expanded particle sizes. Fringe analysis algorithms have been applied to obtain lamellae statistics and highlight nuances in the nanostructure changes after partial oxidation and heat treatment.}, year = {2023}, eissn = {1873-3891} } @article{MTMT:32949798, title = {HRTEM analysis of the aggregate structure and ultrafine microporous characteristics of Xinjiang Zhundong coal under heat treatment}, url = {https://m2.mtmt.hu/api/publication/32949798}, author = {Li, Xueping and Zeng, Qiang}, doi = {10.1038/s41598-022-09113-z}, journal-iso = {SCI REP}, journal = {SCIENTIFIC REPORTS}, volume = {12}, unique-id = {32949798}, issn = {2045-2322}, abstract = {Understanding the change in coal structure during heat treatment is the basis of efficient and clean utilization of coal. In this study, high-resolution transmission electron microscopy (HRTEM) was used to analyse the changes in the aggregate structure and ultramicropores of Zhungdong coal samples (Xinjiang, China) that were heated from ambient temperature to 800 degrees C respectively. Then, the relationship between their HRTEM characteristics and the corresponding reaction activation energy were also analyzed. The results show that the length, curvature, order, layer spacing and stacking height of the aromatic layers of the coal sample vary with an increasing temperature, and are related to the activation energy of the reaction. As the temperature reaches 300 degrees C, the HRTEM characteristics of the heated coal samples are obviously different from those of the raw coal sample. It is shown that the length of lattice fringes is in the range of 0.3-1.15 nm which accounts for approximately 95% of the total number of fringes. The overall orientation of lattice fringes is not good, but there are two main directions. After heating, the number of naphthalenes in the coal samples decreased, while the number of larger aromatic layers increased. The distance between the aromatic layers of the coal sample decreased with an increasing stacking height, the order of the aromatic layers was enhanced, and the number of aromatic sheets with a larger curvature increased. The coal ultramicropores are mainly concentrated from 0.4 to 0.7 nm. Heat treatment reduces the total number of ultramicropores, but the maximum number of pores is increased. The non-six-membered ring and lattice defects lead to the bending of the fringes, the distribution of fatty structures affects the orientation of the fringes, and the relationship between the pore and molecular structure does not exist independently. After heat treatment, the aggregate structure and ultramicropore size of coal have a high correlation with the activation energy. The activation energy is closely related to the 0.6 nmultramicropores. However, the current experiment could not explain the underlying causes of these relationships. The aggregated state in coal is the macromolecular group formed between different aromatic structures, fat structures and other molecules, which is formed by the interaction of internal defects and pores in the molecular group. The structural differences at different temperatures therefore reflect the interaction of different macromolecules in coal.}, year = {2022}, eissn = {2045-2322} } @article{MTMT:32330110, title = {Waste to life: Low-cost, self-standing, 2D carbon fiber green Li-ion battery anode made from end-of-life cotton textile}, url = {https://m2.mtmt.hu/api/publication/32330110}, author = {Jagdale, Pravin and Nair, Jijeesh Ravi and Khan, Aamer and Armandi, Marco and Meligrana, Giuseppina and Hernandez, Francisco Robles and Rusakova, Irene and Piatti, Erik and Rovere, Massimo and Tagliaferro, Alberto and Winter, Martin and Gerbaldi, Claudio}, doi = {10.1016/j.electacta.2020.137644}, journal-iso = {ELECTROCHIM ACTA}, journal = {ELECTROCHIMICA ACTA}, volume = {368}, unique-id = {32330110}, issn = {0013-4686}, abstract = {In this study, self-standing and flexible Li-ion battery negative electrodes made of interconnected two-dimensional carbonized cotton fibers are developed by using a controlled pyrolysis method, and their electrochemical performance in laboratory-scale lithium-based cells is investigated at ambient temperature.

The gasification behavior varied with the initial nanostructure and treatment temperature. At 1273 K the consumption behavior followed a hybrid mode comprised of shrinking core and homogeneous reaction models. However, at 1473 K, a previously unobserved gasification behavior occurred with the soot forming concentric spheres. Here the gasification progressed by initially forming micropores, followed by insufficient permeation of oxidant with the subsequent consumption of the core, ultimately forming hollow particles. Raman spectra and X-ray diffraction patterns indicated there was a transformation from initially ordered to less well-ordered structure. Partial gasification induced disordering to different extents, accompanied by a slight maturing associated with thermal annealing. The crystallites were preferentially consumed along the graphitic edges for coal-derived soot. At the start of gasification, the density of the soot increased but subsequently declined.

The morphology and nanostructure transformations were examined at conversion fractions similar to 0.2, 0.4, 0.6, and 0.8. Three modes of behavior were evident. The behavior of SF-soot followed an internal oxidation model (IOM) at 1273 K. The oxygen was able to fully permeate into the particle core, producing a sphere with variable removal of the interior structure with conversion. However, at the higher temperature, the SF-soot formed a concentric spherical structure with gradual consumption of the inner sphere due to restricted oxygen penetration. The fragmentation of hollow interior particles, on which the available literature is not extensive, was observed from HRTEM and SEM micrographs for the first time. During the oxidation of SF-soot, micropores were mainly generated during the 0-0.2 conversion, while the mesopore surface rapidly increased during the 0.6-0.8 conversion. The X-ray diffraction (XRD) patterns and Raman spectra both show that the oxidation of SF-soot is mainly a disordering process. The graphitic microcrystals were mainly consumed along the longitudinal orientation during the 0-0.2 conversion but were mainly consumed along the horizontal during the 0.4-0.8 conversion. The true densities of SF-soot and carbon black initially increase and then decrease monotonically during oxidation.

One of the oil formulations used a multifunctional DVII (Dispersant Viscosity Index Improver) component with enhanced antiwear characteristics to improve durability of engine components while the other formulation comprised of a conventional additive package. After the completion of engine-dynamometer tests, valvetrain components operating primarily in boundary lubrication regime were inspected for wear and weight loss in order to understand soot induced wear effects. In addition, soot was extracted and characterized using temperature resolved XRD, TEM, XANES, BET, Raman and EDS. XRD phase analysis of residue left behind after soot oxidation showed presence of crystalline compounds embedded in the soot structure (CaSO4, Ca-3(PO4)(2), Zn-3(PO4)(2) and ZnO). These species form ash pre-cursors which get trapped in the DPF (Diesel Particulate Filter) placed in the engine exhaust stream. The turbostratic structure of both soot samples remains the same prior to oxidation; however, the embedded crystalline and amorphous species in the soot structure slightly change with oil formulation. Surface area of the soot measured using BET was found to be inversely proportional to the weight of residue. Additionally, used oil analysis was performed to understand variation in viscosity, wear elements and soot content before and after the test. Findings in this study provide deeper insights into the mechanism for improved wear protection provided by DVII. (C) 2018 Elsevier Ltd.

A two-stage burner was used to characterize the oxidation of soot from different n-butanol blends, 10%, 30%, and 60 mol% in n-dodecane. The two-stage burner isolates the soot oxidation process from the formation process. Soot is formed in a first-stage premixed burner under fuel-rich conditions, while in a second stage, the soot is oxidized under slightly fuel-rich conditions. A scanning mobility particle sizer (SMPS) was used to measure the soot particle size distributions in the flame at different heights during oxidation. Results showed a decrease in particle mass concentration (g/cm(3)) as the fraction of n-butanol increased, which indicates the capability of n-butanol to reduce soot particle number and mass. On the other hand, the results demonstrated that the increasing n-butanol reduces the difference between initial mass of soot particles entering and the final mass of soot particles leaving the second burner. This result implies that increasing the n-butanol concentration decreases the rate of soot oxidation. Two different fuel quality indicators are used to quantify our observations. The first one, "sooting tendency", is calculated to show how the amount of soot formed in the flame is affected by using different n-butanol percentages. The second one, "sooting stability", is defined for quantifying the stability of soot particles against oxidation. The results demonstrated that by increasing the n-butanol percentage, soot formation was suppressed. However, sooting stability increased with higher concentrations of n-butanol. The soot nanostructure was quantified by high-resolution electron microscopy and digital image processing. Image analysis revealed layer arrangement is in correlation with sooting stability. The results of interlayer spacing showed a decrease by increasing n-butanol at the same sampling height. (C) 2013 The Combustion Institute. Published by Elsevier Inc.

The motivation for this study is to improve the understanding of the influence of soot microstructure on its optical properties. The soot sampling positions in the steady ethylene flame correspond to locations of maximum soot mass growth, partial soot oxidation, and quenched oxidation along a common streamline. Visual examination of the HRTEM images suggests that the graphitic crystalline layers of soot undergo increased densification along the sampled streamline in the steady laminar flame. Quantitative image analysis reveals a small decrease in the mean graphitic interlayer spacing (d(002)) with increasing residence time in the high-temperature region. However, the differences in the mean interlayer spacing are far smaller than the spread of interlayer spacings measured for any given soot sample. Post-flame samples from the unsteady ethylene flame show interlayer spacing distributions similar to the lower region of the steady flame. The soot samples from the pool fire show little evidence of oxidized soot and have interlayer spacings similar to the unsteady ethylene flame. Previous research in the carbon black field has demonstrated a direct relation between the graphitic interlayer spacing and the optical absorptivity of the carbon. Consequently, the current HRTEM results offer support to recent measurements of the dimensionless extinction coefficient of soot that suggest that the optical absorptivity of agglomerating soot shows only minor variations for different fuels and flame types.
