“…Upon inclusion of sepiolite and further increasing in the sepiolite loadings have increased the peak intensities of Si-O vibration, corresponding to the content of sepiolite in the NR matrix. Most peaks observed were in good agreement to the literatures 14,15 . This indicates that the sepiolite has original distance between layers of 8.38 A° and was mainly in dehydrated form.…”

The use of mineral fillers in rubber industry has been increasingly focused. Sepiolite is considered as one of the mineral fillers that exploits unique characteristics. This is due to its unique needle-like fibrous and a tunnel-like micro-pore channel structures. Therefore, adding this filler in natural rubber (NR) matrix would bring tremendous advantage. The study was carried out in the form of curing characteristics, tensile properties and morphology together with the dynamic properties. Filling sepiolite to NR has brought to a noticeable enhancement of curing characteristics, tensile properties and morphology. This is contributed to the distinctive structure of sepiolite itself, it provides a better dispersion to the NR. Surface roughness of the composites is visibly found which is responsible for the mechanical properties. Further verification was also monitored through the dynamic properties of the composites. The obtained profiles are in good agreement to the tensile properties and morphological characteristics observed.

“…[24] In Figure 3a we present the vibrational spectrum and the relevant vibration assignments of the neat TmdSx-CN solvent, and of the electrolyte solution (1 mol kg À1 LiTFSI in TmdSx-CN) recorded by attenuated total reflection-Fourier transform infrared spectroscopy (ATR-FTIR). [25][26][27][28][29][30][31][32] To test the chemical stability of both solutions to oxygen and moisture we exposed both (neat disiloxane, and electrolyte) to the atmosphere for 10 minutes.…”

The chemical compatibility of the various compounds and elements used in lithium‐based batteries dictates their safe operation parameters and performance. The lithium salt Li‐bis(trifluoromethanesulfonyl)imide (LiTFSI) has many advantages over the common LiPF6 salt as it does not react with water impurities to form, for example, hydrofluoric acid. To further accommodate safe‐operation chemistry, we use a non‐volatile disiloxane‐based solvent 1,3‐bis(cyanopropyl)tetramethyldisiloxane (TmdSx‐CN). This is a liquid disiloxane functionalized with terminal nitrile groups. In this paper, we report on the electrochemical characterization and the composition of the solid electrolyte interphase (SEI) of 1 mol kg−1 LiTFSI dissolved in TmdSx‐CN in silicon‐lithium batteries. Specifically, we study the SEI formation on silicon nanowire anodes and its composition by several ex‐situ surface techniques (XPS, SEM), and in‐situ via polarization modulation infrared reflectance absorption spectroscopy (PM‐IRRAS). We evaluate the potential application of TmdSx‐CN to silicon‐lithium batteries and conclude that the addition of fluoroethylene carbonate (FEC) at low concentrations (10 wt %) is essential to the formation of an effective SEI. We anticipate that our study will encourage the investigation, design and use of siloxane‐based solvents as safer alternatives to common solvents used in Li‐ion batteries, and specifically as candidate solvents in Li‐metal and silicon‐anode based batteries.

“…Mohammed et al (2013) mention that organic compost from animals, is mostly treated by anaerobic digestion for energy production, and it is a product that may benefit farmers in different manners. The FTIR provided reasonable precision with a root mean square error of 10% using partial least squares analysis (Hepburn et al, 2015).…”

Ranches of Mexico's southeast region have an important energetic potential on their organic waste that remains unexploited. The objective of this work is to present the construction and operation of a floating dome "Biodigester" in a ranch located in Jalapa, Tabasco, Mexico, in addition to the analysis of produced biogas and its electric energy generation. The construction was based in the specifications of a Puxin® biogas plant. The biogas was analyzed using infra-red spectrometry with Fourier transforms. Electric energy was generated using an Energetic ® motor-generator. The methane and carbon dioxide percentage at 90 days of hydraulic retention time (HRT) was 51.51 and 29.05%, respectively. The electric energy generation was 3.58 kWhm-3 .
