Application of TiO Supported on Nickel Foam for Limitation of NO in the Air via Photocatalytic Processes.

TiO was loaded on the porous nickel foam from the suspended ethanol solution and used for the photocatalytic removal of NO. Such prepared material was heat-treated at various temperatures (400-600 °C) to increase the adhesion of TiO with the support. Obtained TiO/nickel foam samples were characterized by XRD, UV-Vis/DR, FTIR, XPS, AFM, SEM, and nitrogen adsorption at 77 K.

Smart Graphite-Cement Composites with Low Percolation Threshold.

The objective of this work was to obtain cement composites with low percolation thresholds, which would reduce the cost of graphite and maintain good mechanical properties. For this purpose, exfoliated graphite was used as a conductive additive, which was obtained by exfoliating the expanded graphite via ultrasonic irradiation in a water bath with surfactant. To obtain evenly distributed graphite particles, the exfoliated graphite was incorporated with the remaining surfactant into the matrix.
