Review: Nucleation in solutions revisited
Tập 38 Số 7-8 - Trang 555-574 - 2003
AbstractExisting and new results in nucleation in solutions are outlined from a
unified point of view. The thermodynamics of the process is considered and
expressions are given for the supersaturation, the nucleation work and the size
of the nucleus in homogeneous or heterogeneous nucleation. It is shown how the
nucleation theorem can be used for a model‐independent determination of the
nucleus si...
Growth and properties of LiGaX2 (X = S, Se, Te) single crystals for nonlinear optical applications in the mid‐IR
Tập 38 Số 3-5 - Trang 379-387 - 2003
AbstractSingle crystals LiGaX2 (X = S, Se, Te) of optical quality were grown,
with transparency ranges at 5 cm‐1 absorption level of 0.32‐11.6 μm, 0.37‐13.2
μm and 0.54‐14.2 μm, respectively. The first two, LiGaS2 and LiGaSe2, have a
wurtzite‐type structure whereas LiGaTe2 is tetragonal (chalcopyrite lattice).
The three refractive indices were measured in the whole transparency ranges of
LiGaS2 an...
The Ostwald Rule of Stages
Tập 30 Số 4 - Trang 443-449 - 1995
AbstractCrystallization from solutions often starts in such a way that
thermodynamically unstable phases appear first followed by recrystallization to
thermodynamically stable phases. This empirical observation, called as Ostwald's
rule of stages, is explamed here on the basis of structure changes of solutions.
Experiments supporting this explanation have been carried out with aqueous
solutions of...
Cobalt phthalocyanine nanowires: Growth, crystal structure, and optical properties
Tập 51 Số 2 - Trang 154-159 - 2016
Cobalt phthalocyanine nanowires with new crystal structure and broad optical
absorption spectra were fabricated by using organic vapor phase deposition
method. The morphology, crystal structure and optical properties of CoPc
nanowires were characterized by SEM, X‐ray diffraction, Fourier transform
infrared and UV‐visible spectroscopies. Analyses of X‐ray diffraction patterns
and Fourier transform ...
Effect of citric acid concentration as emulsifier on perovskite phase formation of nano‐sized SrMnO3 and SrCoO3 samples
Tập 45 Số 10 - Trang 1064-1068 - 2010
AbstractIn this study the effects of citric acid concentration, used as organic
emulsifier, on the perovskite phase formation of the nano strontium manganite or
cobaltite samples were studied. Stoichiometric perovskites in the absence and
presence of citric acid were prepared by drying a solution containing molar
ratio of Sr(NO3)2/Mn(NO3)2·4H2O and Sr(NO3)2/Co(NO3)2·6H2O = 1 followed by
calcinatio...
Influence of grain boundaries intentionally induced between seed plates on the defect generation in quasi‐mono‐crystalline silicon ingots
Tập 50 Số 1 - Trang 124-132 - 2015
This work reports about the growth behavior and defect formation during the
directional solidification of mono‐crystalline lab‐scale silicon ingots in which
split seed crystals were used. Thereby the split seeds have certain
crystallographic orientations which chosen to induce the growth of selected
grain boundaries between the seeded regions. It will be shown that the grain
boundary type which is...
Improved determination of fcc/bcc orientation relationships by use of high‐indexed pole figures
Tập 41 Số 1 - Trang 72-77 - 2006
AbstractThe use of variants to analyze fcc/bcc orientation relationships is
demonstrated by EBSD data. Because of multiply occupied poles in the
stereographic projections low indexed pole figures are not always suitable. This
is mostly caused by the convolution of all scattered individual orientation data
as the single poles cannot resolved in the pole figure. Pole figures of higher
indexed lattic...
Studies on the structural, thermal and optical behaviour of solution grown organic NLO material: 8‐hydroxyquinoline
Tập 42 Số 2 - Trang 195-200 - 2007
AbstractSingle crystal of 8‐hydroxyquinoline (8HQ) having chemical formula
C9H7NO, an organic nonlinear optical (NLO) material has been successfully grown
by slow evaporation solution growth technique at room temperature. The crystal
system has been confirmed from the powder X‐ray diffraction (PXRD) analysis. The
crystalline perfection was evaluated by high resolution X‐ray diffractometry
(HRXRD)....
Crystal growth of mixed‐valence ammonium vanadates
Tập 42 Số 4 - Trang 317-320 - 2007
AbstractA new method has been developed for the synthesis of mixed‐valence
ammonium vanadate crystals. Single crystals of (NH4)2V3O8 were synthesized on a
large scale by hydrothermal reduction of NH4VO3 in ethanol‐H2O solutions in the
presence of triblock copolymer Pluronic P123. The crystals are shining thin
plates with (001) cleavage planes. Calcination of the (NH4)2V3O8 crystals at
300°C or abo...
