A novel route employing UV laser pulses (KrF Excimer, 248 nm) to cleave small aromatic molecules and stitch the generated free radicals into functional nanostructured forms of carbon is introduced. The process differs distinctly from any strategies w

We report the chemical analysis of 47Nb 16Si 25Ti 8Hf 2Al 2Cr alloy sheet exposed in static air at 1200°C for 150, 300, 450, 600 and 900 seconds. This alloy exhibits linear oxidation kinetics. The dendritic phase M5Si3 (with M=Hf and Ti) is observed

Infrared reflection study of CuO in thin oxide films

Autor: K. Kartouni, R. Souchet, M. Lenglet, B. Lefez

Publikováno v: Thin Solid Films. 268:45-48

Cupric oxide in thin film form is studied by infrared reflectance spectroscopy and is characterised by absorption bands at 480 and 540 cm−1 (associated with transverse optical vibration modes) and at 600 cm−1 (associated with longitudinal optical
