“…3 Carbon black consists of solid carbon in a multinuclear structure containing between 90 and 99% elemental carbon, in the form of spherical particles that combine to form a complex agglomerated structure. 4 Due to this complex structure, carbon black exhibits a variety of properties, such as aggregate morphology, microstructure, and particle size, which contribute to the performance of reinforcement in elastomeric compounds. 5 The spherical particles have a microstructure of carbon organized in graphene sheets that are not aligned, in small clusters on the outside (turbostratic structure) and inside the carbon is disorganized (amorphous structure).…”

In the present work, the effect of residence time on the production of biochar by the pyrolysis process of Pinus spp. was investigated. Biochar was produced at three different residence times in the reactor (30, 60, and 240 min). The effect of residence time on the load in the pyrolysis process was evaluated based on the rheometric, physical and mechanical properties of the elastomeric compounds. The shortest residence time, 30 min, produced a biochar with a graphitic structure (turbostratic) that was ideal for the interaction between load and elastomer and caused the least possible disturbance to the crystallization process by stretching the natural rubber, which was observed from the tensile strength, while maintaining the mechanical properties. As the residence time increased, it was observed that the more crystalline structure interfered with the crystallization process of the natural rubber when stretched, causing a decrease in tensile strength and decreasing the interaction between the load- elastomer, thus increasing the vulcanization time of the rubber. The compound was prepared using the filler with the longest residence time (NR/BIO240min).

Antibiotics are commonly detected in natural waters. Suspended particulate matter (SPM) in surface water has a good adsorption capacity for antibiotics, and the organic matter (OM) in SPM is the key factor for this adsorption. We investigated the contribution of OM content and form to the adsorption of tetracycline (TC) and nor oxacin (NOR) in the SPM of Taihu Lake. To change the content and form of OM in SPM, we burned it at 505 ℃ and oxidised it with H 2 O 2, respectively. The OM in the sample that was combusted (expressed as SPM-505 ℃) was almost entirely eliminated, and the adsorption amount of TC decreased by 14.8% when compared to the original sample, while the adsorption amount of NOR decreased by 64.8%, indicating that OM content contributes to the adsorption of antibiotics. Although the OM content in the oxidised sample (expressed as SPM-H 2 O 2 ) decreased, the adsorption amounts of TC and NOR increased by 31.7% and 2.8%, respectively, compared with the original sample. The infrared spectrum and elemental analysis results showed that the morphology of the OM changed, suggesting that the structure of the OM contributes substantially to the adsorption of antibiotics. The contribution of OM to NOR adsorption was greater than that of TC. In conclusion, the results verify the importance of OM in adsorbing antibiotics onto SPM, which may provide basic data for antibiotic migration in surface water.
