A three-step (rotor-stator-microfluidization-rotor stator) protocol was used to prepare 15% lemon essential oil in water emulgels using a mixture of Tween 80 and Span 20 surfactants as low molecular mass emulsifiers and 0.4% low-methoxyl citrus peel pectin as a gelling agent. Ca2+ was used as a gel-promoting agent. Different CaCl2/pectin mass ratio values from 0.3 to 0.7 were used. Emulgels showed a microstructure consisting of oil droplets embedded in a sheared gel matrix, as demonstrated by bright field optical microscopy. Laser diffraction tests showed multimodal particle size distributions due to the coexistence of oil droplets and gel-like particles. Multiple light scattering tests revealed that the physical stability of emulgels was longer as the CaCl2/pectin mass ratio decreased and that different destabilization mechanisms took place. Thus, incipient syneresis became more important with increasing CaCl2 concentration, but a parallel creaming mechanism was detected for CaCl2/pectin mass ratio values above 0.5. Dynamic viscoelastic and steady shear flow properties of the emulgels with the lowest and highest CaCl2/pectin mass ratio values were compared as a function of aging time. The lowest ratio yielded an emulgel with enhanced connectivity among fluid units as indicated by its wider linear viscoelastic region, higher storage modulus, loss modulus and viscosity values, and more shear thinning properties than those of the emulgel formulated with the highest CaCl2/pectin mass ratio. The evolution of the dynamic viscoelastic properties with aging time was consistent with the information provided by monitoring scans of backscattering as a function of sample height

The laboratory experiment “Valorization of waste with high Zn content” was designed to introduce the concept of circular economy and waste recovery to students of the Materials Engineering Degree at the University of Seville (Spain). This laboratory experiment has been carried out every academic year since 2015-16. This document contains the experimental data collected during the laboratory practices, which are necessary to respond to the questionnaire posed to the students. Likewise, the anonymized responses of the students to the pre- and post-laboratory questionnaires that were designed to evaluate the achievement of the pedagogical objectives are included.

The aim of this study was to assess the potential mutagenicity and genotoxicity of graphene oxide (GO) and reduced-graphene oxide (rGO) following the recommendations of the European Food Safety Authority (EFSA). Thus, the mouse lymphoma assay (MLA) and the micronucleus test (MN) were performed in L5178YTk ± cells, and the Caco-2 cells were used for the standard and modified comet assays. The results indicated that GO (0–250 μg/mL) was not mutagenic in the MLA. However, rGO revealed mutagenic activity from 250 μg/mL and 125 μg/mL after 4h and 24h of exposure, respectively. In the MN test, negative results were obtained for both compounds at the concentrations assayed (0–250 μg/mL) for GO/rGO. Moreover, no DNA strand breaks, or oxidative DNA damage were detected in Caco-2 cells exposed to GO (0–250 μg/mL) and rGO (0–176.3 μg/mL for 24h and 0–166.5 μg/mL for 48h). Dataset contains the numerical values of the results obtained regarding to MLA assay 4 and 24 h, MN test 24h and comet assay 24 and 48h., Numerical data of the results of MLA assay, MN test and comet assay

The cytotoxicity response of reduced graphene oxide (rGO) was investigated in monocytes (THP-1) and human T cells (Jurkat). A mean effective concentration (EC50-24 h) of 121.45 ± 11.39 μg/mL and 207.51 ± 21.67 μg/mL for cytotoxicity was obtained in THP-1 and Jurkat cells, respectively. rGO decreased THP-1 monocytes differentiation at the highest concentration after 48 h of exposure. Regarding the inflammatory response at genetic level, changes (up and downregulations) were observed depending on the cell line, the exposure time and the interleukins investigated. Apoptosis/ necrosis genes expression was not altered in THP-1 cells but in Jurkat cells BAX and BCL-2 were downregulated after 4h. Finally, rGO did not trigger a significant release of any cytokine at any exposure time assayed. Dataset contains the numerical values of the results obtained regarding cytotoxicity, differentiation, gene expression and interleukin leakage., Numerical data of the results of cytotoxicity, differentiation, gene expression and interleukin leakage

The objective of this papers is to anatomically describe the bone morphology in the maxillary and mandibular tooth areas, which might help in planning implants post-extraction. CBCT images (Planmeca ProMax 3D) of 403 teeth (208 upper teeth and 195 lower teeth) were obtained from 49 patients referred to the Dental School of Seville from January to December 2014.
