Investigation on capillary force of nanoscale water cluster using a Hybrid AFM-MEMS System

Kwon S., Kim B., Jhe W., Seoul National University, KR

The interaction force between surfaces has a major effect on the behavior of the materials, such as nanoparticles, proteins, various bio-molecules, and so on. The phenomenon of stiction influenced by interaction forces impacts the repetitive [...]

Understanding 2D atomically thin and layered materials beyond graphene using a novel X-ray microscope

Avila J., Chen C., Lorcy S., C. Asensio M., Synchrotron SOLEIL, FR

Research and development of atomically thin, 2D materials from a broad range of layered compounds beyond graphene have sparked enormous scientific interest. The main goal in this field is to disclose the implication of heterogeneities [...]

3D nanostructural analysis of biomaterials by scanning probe nanotomography

Efimov A.E., Agapova O.I., Agapov I.I, Agapova O.I., Shumakov Federal Research Center of Transplantology and Artificial Organs, RU

We have been developing a new methodology and unique instrumentation for 3D reconstruction of the nanoscale volume organization of soft matter – scanning probe nanotomography (SPNT). It combines SPM with an ultramicrotome or cryoultramicrotome and [...]

Nanostructured silicon coupled with Iron Oxide Magnetic Nanoparticles as Enhanced Desorption/Ionization on Silicon Mass Spectrometry for Phosphopeptide Analysis

Tsao C.W., Chen W.Y., Cheng Y.C., Lin C.H., Cheng Y.C., National Central University, TW

Stem cells can differentiated into various cell types which can be used to repair damage organs in regenerative medicine applications. The cell regulation process such as cell division, differentiation, and apoptosis are deeply related to [...]

Photothermal Structural and Optical Changes In GaAs Nanowires

Walia J., Dhindsa N., Flannery J., LaPierre R., Forrest J., Saini S.S., University of Waterloo, CA

The structural and optical changes in vertically etched GaAs nanowires are examined. The nanowires were annealed via photo-thermal conversion, using 100 mW of incident laser power, to induce the onset of arsenic formation. Four nanowire [...]

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 [...]
