Therefore, the commonly espoused pelletization mechanisms need to be extended to account for material transfer between pellet particles, which has not been considered before.”
“Variable-energy positron annihilation spectroscopy (VEPAS) has been applied to the study of the formation and evolution of vacancy-type defect structures in silicon (Si) and the 1.5 mu m thick Si top layer of silicon-on-insulator (SOI) samples. The samples were implanted

with 2 MeV Si ions at fluences between 10(13) and 10(15) cm(-2), and probed in the as-implanted state and after annealing for 30 min at temperatures between 350 and 800 degrees selleck kinase inhibitor C. In the case of SOI the ions were implanted such that their profile was predominantly in the insulating buried oxide layer, and thus their ability to combine with vacancies in the top Si layer, and that of other interstitials beyond the buried oxide, was effectively negated. No measurable differences in the positron response

to the evolution of small clusters of n vacancies (V-n, n similar to 3) in the top Si layer of the Si and SOI samples were observed this website after annealing up to 500 degrees C; at higher temperatures, however, this response persisted in the SOI samples as that in Si decreased toward zero. At 700 and 800 degrees C the damage in Si was below detectable levels, but the VEPAS response in the top Si layer in the SOI was consistent with the development of nanovoids.

“This paper reports the batch-to-batch and vendor-to-vendor variations in the solid-state characteristics of multiple batches of lactose anhydrous from each of three vendors and the subsequent impact of these differences on processability and/or functionality.”
“Temperature and field dependent spin polarized electron momentum distributions in ternary Heusler compound Co2MnSi have been measured using the magnetic Compton spectrometer at

SPring-8, Japan. The experimental Pexidartinib purchase magnetic Compton profile at 10 K reconciles well with the theoretical profile computed using the spin polarized relativistic (SPR) Korringa-Kohn-Rostoker (KKR) method. The temperature and field dependent experimental magnetic profiles have been mainly analyzed to check the role of Mn 3d electrons in the formation of magnetic moments in Co2MnSi. The diffuse contribution from conduction electrons is antiferromagnetically coupled to the spin moment arising from 3d electrons of Co and Mn. The spin moments calculated using SPR-KKR calculations are in good agreement with the present measurements. (C) 2011 American Institute of Physics. [doi: 10.1063/1.3606428]“
“A co-processed excipient was prepared from commercially available crystalline mannitol and alpha-chitin using direct compression as well as spray, wet, and dry granulation. The effect of the ratio of the two components, percentage of lubricant and particle size, on the properties of the prepared co-processed excipient has been investigated.
