Amorphous alloys can be electrodeposited by direct or pulsed current. According to electrocrystallization theory, a high crystallization overpotential produces microcrystalline structure in the deposits. Thus if the amorphous phase consists of microcrystals, pulsed current is preferable for preparing amorphous alloys. However, another newly proposed theory holds that the amorphous phase structu...
A combined analysis of microcrystalline tests followed by LC-MS or GC-MS analysis is described. Microcrystalline tests are shown to be non-destructive as addition products formed were easily dissociated after the application of an appropriate solvent. Subsequent analysis of the sample was done to quantify the recovery of the drug. Examples were performed using the date rape drug γ-hydroxybutyra...
Microcrystals are responsible for some of the most common and complex arthropathies which are often accompanied by intense, severe pain and inflammatory reactions. The main pathogens are crystals of monosodium urate (MSU), responsible for the gout, calcium pyrophosphate (CPP), which deposits also in various clinical forms of arthopathies, and basic calcium phosphate associated with osteoarthrit...
In this paper, we investigate tandem amorphous/microcrystalline silicon solar cells with asymmetric intermediate reflectors grown in the n–i–p substrate configuration. We compare different types of substrates with respect to their light-trapping properties as well as their influence on the growth of single-junction microcrystalline cells. Our most promising back reflector combines a textured zi...
Neoplastic meningitis (NM) results from leptomeningeal dissemination of cancers arising within the central nervous system or metastasizing to the leptomeninges from systemic neoplasms. The inability to produce therapeutic drug levels intrathecally (i.t.) with systemic administration and the minimal efficacy of chemotherapeutic agents currently available for direct i.t. use limit therapy. Temozo...
During the last two decades, the Institute of Microtechnology (IMT) has contributed in two important fields to future thin-film silicon solar cell processing and design: (1) In 1987, IMT introduced the so-called ‘‘very high frequency glow discharge (VHF-GD)’’ technique, a method that leads to a considerable enhancement in the deposition rate of amorphous and microcrystalline silicon layers. As ...
the aim of this work is to probe the influence of nanoclay and turmeric spends content on microcrystalline of vinyl ester hybrid nanocomposites. a series of vinyl ester hybrid nanocomposites have been fabricated with varying amounts of ts viz., 0, 2.5, 5, 7.5 and 10 % w/w along with 2% nanoclay. the microcrystalline parameters such as crystallite size and lattice strain of vinyl ester hybrid na...
USE OF MERCURY POROSIMETRY AND NITROGEN ADSORPTION IN CHARACTERISATION OF THE PORE STRUCTURE OF MANNITOL AND MICROCRYSTALLINE CELLULOSE POWDERS, GRANULES AND TABLETS Sari Westermarck, 2000, University of Helsinki (FIN), pp. 50. ISBN952-91-2534-8 The effects of pretreatment and scanning speed of mercury porosimetry on the mercury porosimetry results of non-hygroscopic mannitol and hygroscopic mi...
