Electro-conductive paths that are mechanically resistant and stable during simulated aging cycles are promising, in relation to the non-invasive application in e-textiles in our everyday surroundings. In the paper, an analysis of the influence of electro-conductive filler, as well as ionic liquid on surface resistance is provided. Authors proved that depending on the tested variant, obtained surface resistance may vary from 50 kΩ (when 50 phr of Ag and [bmim][PF6] ionic liquid applied) to 26 GΩ (when 25 phr of Ag and [bmim][PF6] ionic liquid applied). The samples were also evaluated after simulated aging cycles and the stability of electric properties was confirmed. Moreover, it was proved that the addition of ionic liquids reduced the resistance of vulcanizates, while no significant influence of the extrusion process on conductivity was observed.

The stability factors for Cr6+ and Cr3+ in microbiological media, including temperature, preservation conditions and medium components were studied in this research project, through potassium permanganate oxidation and DPC (Diphenylcarbazide) spectrophotometry. It shows that the protein component mainly influences Cr6+ content changes at pre- and post- heat sterilization to the chromium ionic liquid medium, other than being impacted basically by inorganic salt ions. It also indicates that the method can be introduced into experiment researches for microbe dechromisation i.e. Chromium ion aqueous solution and fluid medium are sterilized separately, and then are made into the chrome ions liquid as per a certain concentration. The concentration of hexavalent chromium ions is affected by preservation time and temperature also. For this reason, chromium ionic liquid medium is kept at low temperature, and as quickly as possible for the test.

new Pt metal based nano-catalytic system was developed using organic-inorganic magnetic framework followed by the user-friendly protocol in good yield. XRD, FTIR, TEM, BET, ICP-OES and solid-state NMR techniques were used to characterize our developed catalytic system. The wellcharacterized ionic liquid bridged-silica supported magnetic Pt nanoparticles were utilized for the selective hydrogenation of carbon dioxide under high-pressure reaction condition (with and without ionic liquid medium). Most promising results were obtained while using the catalytic system (Pt-MagNP@ILSiO2) in 1,3-di (N, N-dimethylaminoethyl)-2-methylimidazolium nonafluorobutanesulfonate ([DAMI] [CF3CF2CF2CF2SO3]) task-specific ionic liquid medium. This TSIL not only provided a high degree of CO2 absorption during the reaction but also enhances the selectivity and the recyclability of the catalytic system up to 8 runs. No sign of Pt metal leaching was recorded during the recyclability test which confirmed the stability of this catalytic system under high-pressure reaction condition.

It was investigated that the intrusion of water into the electrolyte was the most critical reason for the low stability of a dye-sensitized solar cell. To prevent the water intrusion, robust solar cells and submodules with a novel protection layer of metal circuit and tightly sealing package was developed. The excellent stability of the cell with ionic liquid electrolyte at high temperature conditions was also reveled. The resulting cell employing noble construction and ionic liquid electrolyte showed an extremely high stability to pass several endurance tests standardized in JIS for the stability of the photovoltaic submodule.

Conventional thermal fluids with suspended nanoparticles, known as nanofluids, have been developed for heat transfer applications. Heat transfer loss could be reduced significantly if the thermophysical properties of the heat transfer fluid are improved, which to some extent, could reduce the present global environmental challenges associated with energy utilization, such as climate change and global warming. In this work, the role of the concentration of sodium dodecyl-benzene sulfonate (SDBS) in the stability of Al2O3/bio-oil nanofluid is investigated the zeta potential value, and its implications to the viscosity and thermal conductivity of the nanofluid are explored. The bio-oil based nanofluid is fixed using a two-step method in which the prepared base fluid is added with 13-nm alumina nanoparticles powder. Various weight fractions of SDBS (0.1, 0.2, 0.4, 0.6, and 1.0 wt%) are used for both 0.1 and 0.2 wt% Al2O3 to investigate the significance of the stability of a nanofluid on its thermal conductivity and viscosity. Results indicate that a stable nanofluid has reduced viscosity and increased thermal conductivity.

Ultrasound Power

Ultrasound was adopted to prepare emulsion fuels between bio-oil and 0# diesel. The effects of ultrasound power and treating time on the stability of emulsion fuels were investigated. Excellent stability with stable time as long as 35 hours was obtained under an ultrasound power of 80W and a treating time of 3 minutes. Malvern nanometer particle size analyzer (Zetasizer Nano S90) was used to study the droplet size of emulsion fuels. The emulsion fuels with smaller droplet size had longer stable time. And the droplet size of the optimal emulsion fuel was around 0.4 um.
