A hydrothermal method of catalytic nanotube synthesis has been shown to produce high-aspect-ratio, multiwall, capped carbon nanotubes, which are hollow and contain a high-pressure encapsulated aqueous multicomponent fluid displaying clearly segregated liquid and gas by means of well-defined curved menisci. Thermal experiments are performed using electron irradiation as a means of heating the contents of individual nanotubes in the high vacuum of a transmission electron microscope (TEM). The experiments clearly demonstrate that TEM can be used to resolve fluid interface motion in nanochannels. Good wettability of the inner carbon walls by the water-based fluid is shown. Fully reversible interface dynamic phenomena are visualized, and an attempt is made to explain the origin of this fine-scale motion. Experimental evidence is presented of nanometer-scale liquid films rapidly moving fluid along the nanochannel walls with velocities 0.5 mum/s or higher. (C) 2002 American Institute of Physics.

Impurity-driven nanocrystallization of Zr-based bulk amorphous alloys Akdeniz, Mahmut Vedat; Mehrabov, Amdulla (American Scientific Publishers, 2008-02-01) The effect of oxygen content and Ti addition on the glass forming ability (GFA) and crystallization kinetic of Zr-based bulk glass forming alloys have been studied by means of thermal analysis and X-ray diffraction techniques. Presence of oxygen triggers the formation of a nanocrystalline metastable f.c.c. Zr-2 Ni-type phase which can act as heterogenous nucleation sites for the formation of dendrites during solidification. An increase in oxygen content changes the crystallization behaviour from a single- t...
In situ multiphase fluid experiments in hydrothermal carbon nanotubes Gogotsi, Y; Libera, JA; Güvenç Yazıcıoğlu, Almıla; Megaridis, CM (2001-08-01) Hydrothermal multiwall closed carbon nanotubes are shown to contain an encapsulated multiphase aqueous fluid, thus offering an attractive test platform for unique in situ nanofluidic experiments in the vacuum of a transmission electron microscope. The excellent wettability of the graphitic inner tube walls by the aqueous liquid and the mobility of this liquid in the nanotube channels are observed. Complex interface dynamic behavior is induced by means of electron irradiation. Strong atomic-scale interaction...
A NONIONIC SURFACTANT VESICLE-IN-WATER-IN-OIL (V/W/O) SYSTEM - POTENTIAL USES IN DRUG AND VACCINE DELIVERY YOSHIOKA, T; SKALKO, N; Gürsel, Mayda; GREGORIADIS, G; FLORENCE, AT (Informa UK Limited, 1995-01-01) An aqueous dispersion of niosomes (non-ionic surfactant vesicles) emulsified in an external oil phase forms the vesicle-in-water-in-oil (v/w/o) system described in this paper. The properties of the surfactant used to form the vesicles, the surfactant or surfactant mixture used to stabilize the emulsion and the nature of the oil phase can be changed to provide systems of different capacities for drug or antigen and different release characteristics. The same nonionic surfactant is used as the principle amphi...
Simulation of crystallization and glass formation processes for binary Pd-Ag metal alloys Kart, HH; Uludogan, M; Cagin, T; Tomak, Mehmet (2003-09-12) Glass formation and crystallization process of Pd-Ag metallic alloys are investigated by means of molecular dynamics simulation. This simulation uses the quantum Sutton-Chen (Q-SC) potential to study structural and transport properties of Pd-Ag alloys. Cooling rates and concentration effects on the glass formation and crystallization of binary alloys considered in this work are investigated. Pd-Ag alloys show the glass structure at fast cooling rates while it crystallizes at slow cooling rates. Increment of...
Flotation responses to the morphological properties of particles measured with three-dimensional approach Hicyilmaz, C; Ulusoy, U; Bilgen, S; Yekeler, M (2005-02-07) Morphological properties of barite particles ground by autogenous and ball milling were examined by three-dimensional methods, namely, Brunauer-Emmett-Teller (BET) nitrogen adsorption and Permaran methods in terms of surface roughness and acuteness, respectively. The experimental study showed that autogenously ground products have lower roughness and acuteness. On the other hand, Hallimond tube flotation tests were performed to evaluate the floatability of those particles ground in different environments. M...
