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 interactions between the entrapped liquid phase and the wetted terminated graphite layers are revealed by means of high-resolution electron microscopy. The documented phenomena in this study demonstrate the potential of implementing such tubes in future nanofluidic devices. (C) 2001 American Institute of Physics.

Electron microscope visualization of multiphase fluids contained in closed carbon nanotubes Güvenç Yazıcıoğlu, Almıla; Nıcholls, Alan; Gogotsı, Yury (2005-01-01) Aqueous multiphase fluids trapped in closed multiwall carbon nanotubes are visualized with high resolution using transmission electron microscopy (TEM). The hydrothermally synthesized nanotubes have inner diameter of 70 nm and wall thickness 20 nm, on average. The nanotubes are hydrophilic due to oxygen groups attached on their wall surfaces. Segregated liquid inclusions contained in the nanotubes under high pressure can be mobilized by heating. A resistive heating stage is utilized to heat a thin membrane ...
In situ atom trapping of Bi on W-coated slotted quartz tube flame atomic absorption spectrometry and interference studies KILINÇ, ERSİN; BAKIRDERE, Sezgin; AYDIN, FIRAT; Ataman, Osman Yavuz (2013-11-01) Analytical performances of metal coated slotted quartz tube flame atomic absorption spectrometry (SQT-FAAS) and slotted quartz tube in situ atom trapping flame atomic absorption spectrometry (SQT-AT-FAAS) systems were evaluated for determination of Bi. Non-volatile elements such as Mo, Zr, W and Ta were tried as coating materials. It was observed that W-coated SQT gave the best sensitivity for the determination of Bi for SQT-FAAS and SQT-AT-FMS. The parameters for W-coated SQT-FAAS and W-coated SQT-AT-FAAS ...
In vitro and in vivo properties of graphene-incorporated scaffolds for bone defect repair Jodati, Hossein; Yilmaz, Bengi; Evis, Zafer (2021-01-01) The employment of graphene and its derivatives, graphene oxide and reduced graphene oxide, is extending from bioimaging and fabrications of biosensors to drug delivery and tissue engineering in the biomedical area. Graphene family-incorporated scaffolds, used in bone tissue engineering and bone regenerative medicine, profit superior properties of these materials, such as enhanced mechanical properties, large surface area, and the existence of functional groups. At the same time, problems related to cytotoxi...
Multiscale Modeling of the Morphology and Properties of Segmented Silicone-Urea Copolymers Yıldırım, Erol; Yurtsever, Ersin; Yilgor, Iskender; Yilgor, Emel (Springer Science and Business Media LLC, 2011-9-9) Molecular dynamics and mesoscale dynamics simulation techniques were used to investigate the effect of hydrogen bonding on the microphase separation, morphology and various physicochemical properties of segmented silicone-urea copolymers. Model silicone-urea copolymers investigated were based on the stoichiometric combinations of alpha,omega-aminopropyl terminated polydimethylsiloxane (PDMS) oligomers with number average molecular weights ranging from 700 to 15,000 g/mole and bis(4-isocyanatocyclohexyl)meth...
Kinetics and Mechanisms of Isothermal Devitrification in Amorphous Cu50Zr50 Cullinan, Tim; Kalay, Ilkay; Kalay, Yunus Eren; Kramer, Matt; Napolitano, Ralph (2015-02-01) The crystallization kinetics and microstructural dynamics associated with devitrifying a melt-spun Cu50Zr50 metallic glass were investigated using isothermal treatments, in situ high-energy synchrotron X-ray diffraction, conventional and high-resolution transmission electron microscopy, and differential scanning calorimetry. The analysis of isothermal transformations allows us to more clearly unravel the complex interplay between nucleation and growth of competing stable and metastable phases. The isotherma...
