Biodiesel is considered an important substitute of diesel oil. Traditionally, it is obtained by the transesterification of vegetable oils with methanol or ethanol, catalyzed by NaOH or KOH. Heterogeneous catalysts have been studied with the aim at facilitating and diminishing costs with purification stages. In the present work, the Na/Nb2O5 system was evaluated on the reaction of soybean oil with ethanol. It was verified, by DRX and IR, that the niobia calcined at 500C and impregnated with sodium underwent greater structural alterations than that treated at 300C. These modifications allowed the generation of basic properties on niobia surface (Hammett and CO2 adsorption /IR). This catalyst showed the highest conversion (30%) among the used materials. The method chosen for evaluating the catalysts yield was the 1H NMR spectroscopy.

Investigation on functional genome research may contribute to the knowledge of functional roles of different mRNAs and miRNAs in bone cells of osteoporotic animals. Currently, few studies indicate the changes in gene modulation that osteoporosis causes in osteoblastic cells from different sites. Thus, the purpose of this investigation was to evaluate cell viability, alkaline phosphatase activity and modulation of mRNAs/miRNAs in osteoblastic cells from calvaria and bone marrow by means of microarray technology. Wistar female rats were divided in sham operated and ovariectomized groups. After 150 days of ovariectomy, cells were isolated from both sites to perform cell culture. Results showed that calvaria cells from ovariectomized rats had a decrease in viability when compared to control groups and to bone marrow cells from osteoporotic rats after 3 days. Alkaline phosphatase activity decreased in calvaria cells from ovariectomized rats whereas it was increased in bone marrow osteoblastic cells in the same group. Microarray data analysis showed 5447 differentially expressed mRNAs and 82 differentially expressed miRNAs in calvaria cells. The same way, 4399 mRNAs and 54 miRNAs were expressed in bone marrow cells. mRNAs associated with bone metabolism such as Anxa5, Sp7, Spp1, Notch1 were distinctively modulated in both sites, as well as miRNAs such as miR-350, miR-542-3p, miR-204-5p, and miR-30e-3p. The RNA species identified in this study could be further used as targets for treatment or prevention of osteoporosis.

This research presents an efficient technique to enhance the catalytic activity, surface area and total basicity of CaO with hydration-dehydration process to be the catalyst for the transesterification of palm oil to biodiesel. The catalytic performance of the resulted catalyst was tested via transesterification reaction of palm oil at room temperature (30 ± 2 C) and was compared against commercial CaO and CaO derived from natural calcium carbonate sources. Under the optimal reaction conditions (catalyst loading of 5 wt%, methanol to oil molar ratio 12:1), FAME yields were approximately 94% for CaOHY and 60.5%, 55.3%, 49.5% and 51.4% for CaOcom, CaOegg, CaOgol and CaOriv as catalysts, respectively. Catalyst reusability and scaling up of biodiesel production from 50 mL to 1.5 L were also investigated. The obtained biodiesel product after purification and treatment process showed high quality fuel properties within the range of biodiesel standard and similar with high-speed diesel. Furthermore, the used CaOHY as a solid heterogeneous catalyst at room temperature was not only low-cost but also environmentally-friendly, showing a high potential in the biodiesel production.

Conductive materials have been incorporated in anaerobic bioreactors to stimulate direct interspecies electron transfer (DIET), a recently discovered microbial electron-sharing network. Previous studies emphasized the significance of electrocatalytic features associated with DIET, while research gaps are remaining in the understanding of how different operating temperatures and substrate variation will affect those electrochemical characteristics. Consequently, this study examined various electrochemical features, including biomass conductivity, pilA gene, heme-binding proteins, and electron transfers rates (kapp) for methanogenic biomass from conductive carbon fibers amended anaerobic bioreactors operated under different temperatures (20, 37, and 55 C) with substrate variation (ethanol/propionate). Our results demonstrated a distinct temperature-dependent correlation between biomass conductivities, pilA gene, and heme-binding proteins, suggesting operating temperature would influence the relative contributions of various DIET routes (via pili, redox proteins, and conductive materials). When fed with ethanol, the estimated kapp was the highest at 37 C (0.0033 s?1 vs 1.1 d?1), followed by 20 C (0.0018 s?1 vs. 0.74 d?1), and 55 C (0.0012 s?1 vs. 0.29 d?1), which were positively correlated with the estimated methanogenesis rates. While methanogenesis performance was independent of electron transfer rates (0.0026?0.0032 s?1) during operation with propionate; only carbon fibers amended bioreactor operated at 37 C showed stable performance in response to substrate variation. Thus, it appeared that bioreactors operated under different temperatures might face a different level of instability caused by substrate variation. Overall, our results linked electrocatalytic features of biomass with temperature and substrate variation, suggesting the importance of temperature-dependent optimization of DIET for improving anaerobic digestion of complex organic feedstock.

Organic dyes derived from phthaleins have a large number of industrial applications and can be synthesized using a Lewis acid by Friedel?Crafts acylation, followed by an addition reaction to the carbonyl compound. This work aims to investigate the use of NbCl5 as a catalyst for the acylation reaction. The behavior of the phthalein derivatives in several solvents and when subjected to different pH conditions was studied. These compounds showed a color-changing effect depending on the pH and solvent, making them useful for applications as indicators. The phthaleins change their conformations depending on the condition of the medium. Photophysical studies of these compounds were carried out through their UV?Vis absorption spectra. Here, we show the umbrella-like conformation change of phthalein derivatives that depend on the solvent and the pH of the medium.

Objective This study analyzed the behavior of human osteoblasts cultured on porous titanium specimens, with and without biomimetic treatment, compared to dense titanium. Design The experiment had seven groups: Group 1: cells cultured on polystyrene of culture plate wells; Group 2: cells cultured on dense titanium specimen; Group 3: specimen with 33.79% of pores; Group 4: 41.79% of pores; Groups 5, 6 and 7: specimens similar to groups 2, 3 and 4, yet with biomimetic treatment. Real time-polymerase chain reaction with reverse transcription of the following genes was performed: prostaglandin E2 synthase, integrin beta1, osterix, Runx2, Interleukin 6, macrophage colony stimulating factor, apolipoprotein E and others. The study achieved data on cell adhesion, growth and viability, total protein content, alkaline phosphatase activity and quantity of mineralized nodule formations. Data were statistically evaluated. Results Adherent cells and alkaline phosphatase activity were similar in titanium specimens, regardless of the groups. Biomimetic treatment reduced the total protein activity and the viability of tested cells. Most tested genes had statistically similar expression in all groups. Conclusion The tested porosities did not cause alterations in osteoblast behavior and the biomimetic treatment impaired the biocompatibility of titanium causing cytotoxicity.

Disappearing inks can be used for forgeries in many fields. In this study, thymolphthalein indicator solution was prepared as a disappearing ink. A total of 54 different solutions containing thymolphthalein were prepared at six different concentrations and nine different pH values. Among the prepared solutions, 0.16 g/50 mL and 0.32 g/65 mL thymolphthalein at pH 14 were the optimum solutions that were not distinguishable from regular ink when applied to promissory note. Fountain pens were filled with the abovementioned ink solutions and applied to promissory notes for experimental purposes. After 40 h, ink residues were not visible on promissory notes written with the ink with the optimum pH (pH = 14) value. To decipher the entries that disappeared, an instrumental method (Video Spectral Comparator-8000) and a chemical method (using NH3 vapor) were used, succeeded at 0.32 g/65 mL, but failed at 0.16 g/50 mL thymolphthalein.

Efficient lipid extraction is one of the main remaining challenges for full-scale production of biodiesel from urban sewage sludge, a low-cost feedstock. The common approach is to extract lipids from dewatered or dry sludge by means of organic solvents. However, sludge dewatering and drying are energy-consuming and represent more than 50% of the total production cost. Direct liquid-liquid extraction of lipids has been poorly explored; only extraction using hexane as solvent is described in the literature. This study focuses on the optimization of the extraction of lipids from wet raw urban sewage sludge at room temperature. This optimization is conducted varying solvent, pre-treatment, number of extraction steps, contact time and ratio sludge to solvent. The optimized method gives larger lipid amount (34.5%wt dry matter (DM)) than using hexane extraction (32.8%wt DM). Finally, the potential of lipid fractions extracted from eight sludge samples for biodiesel production was evaluated through the determination of acid value and free fatty acid (FFA) content, saponification number and fatty acid composition.

Chemistry is traditionally divided into organic and inorganic chemistry. category: benzofuran, The former is the study of compounds containing at least one carbon-hydrogen bonds.In a patent，Which mentioned a new discovery about 125-20-2

Two new cyanate monomers simultaneously containing phthalide group and different alkyl substituents on the phenylene rings (o-PCY and t-PCY) and the Phenolphthalein-based cyanate (p-PCY) were successfully synthesized by the reaction of o-cresolphthalein, thymolphthalein and phenolphthalein with cyanogen bromide in the presence of triethylamine, respectively. Their chemical structures were confirmed by means of FTIR, NMR and elemental analysis methods. All these monomers owned sufficiently wide processing temperature windows and could be readily cured without the addition of catalyst. The dynamic mechanical analysis (DMA) results showed that the introduction of phthalide structure into the polycyanurate network could effectively improve the thermal properties of the cyanate ester (CE) resin. Especially, the Tg values of the fully cured p-PCY, o-PCY and t-PCY resins are 362 C, 328 C and 298 C, respectively, which are apparently higher than that of most bisphenol-based cyanate resins reported in the literatures (190-290 C). The thermal and thermo-oxidative properties as well as the water absorptions of the cured products were compared with those of the bisphenol A cyanate resin (BACY), and the structure-property relationships were explained according to the chemical structures and crosslinking densities of the formed polymer networks. The high-Tg thermosetting materials thus prepared are expected to expand the usage of CEs to areas where higher temperature requirements are encountered.
