Method to prepare ternary methanol electro-oxidation catalysts for direct methanol fuel cell applications by Yousaf, Ammar Bin

“…The highest catalyst activity of 12.36 mA/mg has been found for the Pt-Ru/NiO-MC, which is higher than the commercial Pt-Ru/C (E-TEK) catalyst. The measured catalytic activity decreased in the order: Pt-Ru/NiO-MC > Pt-Ru/CoO-MC > Pt-Ru/Fe2O3-MC > Pt-Ru/C (E-TEK). …”

Modified zno nanoparticles using iron ions (Fe3+) for photo-catalytic degradation of toxic pollutants under sunlight by Ba-Abbad, Muneer M.

“…The photocatalytic activities of pure ZnO and Fe-ZnO samples were evaluated based on the degradation of 2-chlorophenol in an aqueous solution under the sunlight. The samples with a small concentration of Fe3+ ions showed enhanced photocatalytic activity with an optimal maximum performance at 0.5 wt. %. …”

MODELING AND OPTIMIZATION OF DISTRICT COOLING SYSTEM by ISMAEN, RABAH

“…The hybrid-DCS configuration has the lowest operation cost and the highest environmental performance as it decreases pollution up to 89.5%. The thermal-DCS configuration becomes economically attractive only at high electricity tariff and medium to high available installation area, and decreases the pollution up to 43.76%. …”

Electrically conductive hybrid organic crystals as flexible optical waveguides by Li, Liang

“…The elements respond rapidly to temperature by curling or uncurling in about 0.2 s, which in one typical case corresponds to exceedingly fast deformation and recovery rates of 2187.5° and 1458.3° , respectively. In cyclic operation mode, their conductivity decreases less than 1% after 10,000 thermal cycles. …”

Investigation on the effect of LiTFSI salt on PVDF-based Solid Polymer Electrolyte Membranes for Lithium-Ion Batteries by Arro, Christian

“…The drawbacks of increased LiTFSI content were evident on the mechanical performance with decreased thresholds on the tensile strength. Inversely, improvements on the dielectric performance and conductivity were observed with excellent workability from a wide electrochemical stability window of 0.5 to 3.64 V vs. …”
