C60fullerene nanofibers (FNFs) were for the first time prepared by a volatile diffusion method using toluene as solvent and isopropyl alcohol as precipitation agent in room temperature, 25°C. FNFs with different lengths, aspect ratios, and morphologies could be fabricated by changing incubation time. Meanwhile, as for a crystal growth process, a possible mechanism of the formation of the crystal of FNFs was proposed in which the short and thin FNFs are the result of crystal growth, and self-assembly happens between the short fibers and thus leads to the formation of thick and long bundles of the FNFs.

Traditional Understanding

AbstractCharacteristics of beam-recrystallized Si-on-insulator (SOT) and Ge-on-insulator (GOI) material systems are compared for the first time to gain complementary understanding of the crystallization mechanism that would benefit both systems. In general, GOI has been found to behave quite differently from SOI. In SOI, Si yields sub-boundaries; in GOI, Ge generates twinned or faceted crystals. In GOI, too, sub-boundary-like features were observed, but only occasionally in the midst of twinned crystals. Also observed in GOI was the phenomenon of seeded crystallization breakdown, where defect-free crystals from the seed abruptly turn into defect-laced crystals at a certain distance from the seed. This phenomenon is highly characteristic in SOI, but has never been reported for GOI. These findings are compared and discussed in light of the traditional understanding of crystal growth.

The crystal growth kinetics in the deeply undercooled Zr50Cu50 melt was studied with the electromagnetic levitation technique. The maximum growth rate umax was, for the first time, demonstrated in undercooled metal and alloy melts, and this allowed us to construct the complete profile of crystal growth kinetics in the whole undercooling region of Zr50Cu50 melt. In deep undercooling region near glass transition, the diffusion-controlled crystal growth mechanism accounted for the growth kinetics, while at lower undercooling the profile around umax remarkably differed from what the classical growth theory covers.

To date, crystals of Tutton salts with the general formula (M+)2M2+(SO4)2*6N2O (where M+- alkali metal or ammonium, M2+ - bivalent metal - Co2+, Ni2+) are used as a materials for ultraviolet (UV) filters. Only in recent year effort of ternary crystal growth has been taken. The main problem of mixed crystal growth from liquid solution is high level of the crystal inhomogeneity, which leads to generation of the elastic stress, inclusion trapping and micro- and macrocrack formation in the bulk crystal. For the first time the optically homogeneous mixed K2CoxNi(1 – x)(SO4)2 · 6H2O (KCNSH) large single crystals have been grown from solutions of different compositions by the temperature-reduction technique. Precise X-ray experiment of three mixed crystals was carried out by four-circle diffractometer CAD-4F and XcaliburS diffractometer with two-dimensional CCD detector at the room temperature. KCNSH crystals belong to the monoclinic space group P2(1)/c. Each Co2+ or Ni2+ ion is coordinated with six H2O molecules, forming a distorted octahedral (Co(H2O)6)2+ and (Ni(H2O)6)2+ unit. With increasing content of nickel ions in the crystal, the octahedral unit is narrowed and the unit cell volume is decreased. Chemical formulas refined using diffraction data are K2Co0.657Ni0.343(SO4)2·6H2O, K2Co0.226Ni0.774(SO4)2·6H2O and K2Co0.216Ni0.784(SO4)2·6H2O. Ratios of isomorphic cobalt and nickel components in the mixed crystals are conformed to data obtained by atomic emission spectroscopy. Effect of the Co2+ and Ni2+ ion ratio in KCNSH single crystal to crystal quality is considered.
