TL;DR: In this article, the methode CVD is used to prepare cristallites de silicium. Butteau et al. interpretation des resultats experimentaux en termes de la mesure de la taille du grain des cristalites de sand.

TL;DR: In this paper, anion doping was used to enhance the ferromagnetic properties of BiFeO 3 (BFO) up to nearly two order for x ǫ = 0.25 compared with x Â= 0.

TL;DR: Very intensive red light emission from C60 trapped in 13X molecular sieve has been observed, and it is attributed to the active forbidden transition of C60 anion due to the interaction of C 60 with the sketch structure of 13X mSieve as discussed by the authors.

TL;DR: In this paper, a new peak at 544 nm was observed, which is believed to originate from the trapped C 60 within a NiY molecular sieve, from PLE measurements, the transfer of carriers from Ni ions to their adjacent C 60 molecules is deemed to be responsible for the PL and its enhancement, PLE, PL and EPR measurements indicate the coordination of Ni ions on C60 molecules in supercages of NiY zeolite.

TL;DR: Several microstructural parameters can be obtained from the HWHM (half width at half maximum) Γ of the TO-like mode and the peak positions in the Raman spectra of non-crystalline silicon materials.
