for the annealing treatment of the four gels mentioned above. Annealing has also been done at 650 °C in an attempt to obtain nanometric particles of chromites (MCr 2 O 4 ) {M = Cu, Ni, Zn, and Co} and to find out their magnetic properties which could

-spun polymeric/inorganic composite fibers are calcined to remove the organic material. Proper calcination is a key step in obtaining high-quality inorganic nanofibers, as they are very brittle and can easily disintegrate to nanoparticles. Up to now, in annealings

annealing at 1323 K for 30 min is shown in Fig. 4 . The exothermic and endothermic event during cooling and heating were detected at ∼348 and 598 K, respectively. It is found from the calculations performed by some researchers [ 21 , 22 ] that M s

Introduction Solar cells made of P3HT:PCBM are the state of the art for polymer:fullerene solar cells since the blend can generate 3.5–5% efficiency after post production annealing [ 1 ]. Annealing treatments increase the

Abstract  

The effect of pressure on neutron irradiated potassium chromate and potassium dichromate has been studied. The retention was found to increase with pressure in both salts, mainly at the expense of DP precursors. Thermal annealing studies in samples which prior to heating had been compressed were also made.
