Effect of Reactive Ball Milling Time on the Hydrogenation/Dehydrogenation Properties of Nanocomposite MgH2/7TiMn1.5 Powders

Sherif El-Eskandarany M., Al-Matrouk H., Shaban E., Al-Duweesh A., Kuwait Institute for Scientific Research, State of Kuwait, KW

Reactive ball milling (RBM) technique was employed to synthesize ultrafine powders of -MgH2 phase coexisted with small mole fractions of -MgH2 phase. The metal hydride powders were prepared at room temperature under 50 bar of [...]

Nanoanalysis of Gas Assisted Ion Etching of High Density Polyethylene using FIB/SEM Platforms for the Development of Functional Surfaces

Sezen M., Bakan F., Sabanci University, TR

Although soft matter, such as polymers, are very much prone to react on electron/ion beam irradiation, it is well possible to turn degradation dependent physical/chemical changes from negative to positive when materials are exposed to [...]

Characterization on nanoparticle drug delivery carriers

Murphy C., Jankevics-Jones H., Malvern Instruments Ltd, UK

Nanoparticle controlled drug delivery technology represents a rapidly advancing arena in medical treatment. These delivery systems offer numerous advances compared to conventional dosage forms which include improved efficacy, reduced toxicity and improved patient compliance and [...]

The Effect of Sintering Conditions on the Formation of Hydroxyapatite-Boron Nitride Nanocomposites

Bakan F., Sezen M., Goncu Y., Ay N., Gecgin M., Sabanci University, TR

Being the main inorganic constitution of hard tissues (bone and teeth),calcium phosphates has been applied in medical and dental applications in hard tissue repair. Hydroxyapatite (HAp) ceramics have attracted attention because of their excellent osteoconductive [...]

Viscoelastic Contact Resonance Force Microscopy of Polymers in Liquid

Churnside A.B., Tung R.C., Aziz A., Bryant S., Killgore J.P., NIST, US

Contact resonance force microscopy (CR-FM) is an AFM-based technique for quantitatively determining the nanoscale mechanical properties of materials. In CR-FM, the resonant properties of an AFM cantilever in contact with the surface are interpreted as [...]

3D Nanostructuring and Nanoanalysis of Human Enamel and Dentin Using Focused Ion Beams

Sadighikia S., Sezen M., Sabanci University, TR

This study particularly focuses on three dimensional nanoanalysis of human dentin and enamel samples, using FIB nanostructuring methods such as FIB tomography and preparation of 3D TEM samples. All biological tissues have three dimensional features [...]

Comparison of carbon nanotube data collected using two microscopy methods: dark-field hyperspectral imaging and electron microscopy

Eastlake A.C., Geraci C.L., NIOSH, US

Currently, the National Institute for Occupational Safety and Health (NIOSH) Nanotechnology Research Center uses a modified version of the NIOSH Manual of Analytical Method 7303 (Elements by ICP) and electron microscopy (either scanning or transmission) [...]

Insight into bacteria: magnetosomes chains under photoemission electron and scanning electron microscopes

Keutner C., von Bohlen A., Berges U., Espeter P., Schneider C.M., Westphal C., TU Dortmund University, DE

Magnetotactic bacteria (MTB) are forming magnetosome chains consisting of greigite or iron oxides. In technological, medical, and environmental applications magnetosomes are considered as perspective material. Among all techniques applied to MTB, two providing spatial, chemical, [...]
