Fabrication of Electroless Plated Nano Porous Gold Film for Trace Heavy Metal Ion Detection In Sensor Applications

Bhagavathula S., Ramanan S.R., Kim S.K., Krishnan J.N., BITS Pilani, K. K. Birla Goa Campus, IN

Nano porous gold film was fabricated by electroless plating with Potassium Gold Cyanide as plating solution. E-beam deposited Cu substrates were chosen for plating. The electroless plated gold was investigated through XRD and SEM. SEM [...]

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 [...]
