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.

Food safety is a major factor affecting public health and the well-being of society. A possible solution to control food-borne illnesses is through real-time monitoring of the food quality throughout the food supply chain. The development of emerging technologies, such as active and intelligent packaging, has been greatly accelerated in recent years, with a focus on informing consumers about food quality. Advances in the fields of sensors and biosensors has enabled the development of new materials, devices, and multifunctional sensing systems to monitor the quality of food. In this Review, we place the focus on an in-depth summary of the recent technological advances that hold the potential for being incorporated into food packaging to ensure food quality, safety, or monitoring of spoilage. These advanced sensing systems usually target monitoring gas production, humidity, temperature, and microorganisms’ growth within packaged food. The implementation of portable and simple-to-use hand-held devices is also discussed in this Review. We highlight the mechanical and optical properties of current materials and systems, along with various limitations associated with each device. The technologies discussed here hold great potential for applications in food packaging and bring us one step closer to enable real-time monitoring of food throughout the supply chain.

Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments. category: benzofuran. Introducing a new discovery about 125-20-2, Name is Thymolphthalein

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.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.category: benzofuran, you can also check out more blogs about125-20-2

Singlet oxygen was shown to be involved in the mechanism of fading on a clay surface of a series of the triphenylmethane (TPM) dyes used in commercial carbonless copying paper. The dyes adsorbed on clays were found to be singlet oxygen sensitisers and the singlet oxygen produced reacted with the dyes themselves. The rate of fading of a particular dye depended upon the structure of the dyes, fluorans degrading faster than phthalides.

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.
