Nanoindentation of Carbon Nanostructures
Journal of Nanoscience and Nanotechnology, 2016In the present research paper carbon nanostructures viz. single walled carbon nanotubes, multi-walled carbon nanotubes, single walled carbon nanohorns and graphene nanoplatelets have been synthesized by CVD technique, hydrothermal method, DC arc discharge method in liquid nitrogen and microwave technique respectively. After synthesis 5 mm thick pallets

Nanoindentation and storage of teeth
Journal of Biomechanics, 2002This study determined changes in nanomechanical properties of dentin and enamel during storage in deionized water, calcium chloride buffered saline solution and Hank's balanced salts solution (HBSS). Atomic force microscopy based nanoindentation showed that storing teeth in deionized water or CaCl(2)-solution resulted in a large decrease in elastic ...

Instrumented nanoindentation is a valuable method for mechanical characterization. Typically, sharp tips are used to indent surfaces and wellestablished techniques used to determine the hardness and moduli values of a wide range of materials. Spherical indentation tips, though less common, offer the distinct advantage of providing useful insight into ...

Piezoelectric nanoindentation (PNI) has been developed to quantitatively address electromechanical coupling and pressure-induced dynamic phenomena in ferroelectric materials on the nanoscale. In PNI, an oscillating voltage is applied between the back side of the sample and the indenter tip, and the first harmonic of bias-induced surface displacement at

This present work focuses on the surface characterization of reactor-thermoplastic-polyolefin copolymers (R-TPO) for automotive applications to deduce an appropriate parameter as a measure of the surface stickiness behavior. Therefore, nanoindentation experiments are performed and the well-known mechanical contact properties have been determined ...

Instrumented nanoindentation in musculoskeletal research
Progress in Biophysics and Molecular Biology, 2022Musculoskeletal tissues, such as bone, cartilage, and muscle, are natural composite materials that are constructed with a hierarchical structure ranging from the cell to tissue level. The component differences and structural complexity, together, require comprehensive multiscale mechanical characterization.

Nanoindentation of dental composites
Journal of Biomedical Materials Research Part B: Applied Biomaterials, 2005AbstractThe intent of this project was to evaluate the elastic modulus and hardness of four composites with different fillers, a microfill, a hybrid, a dental resin cement, and a fiber filler, using nanoindentation. An indentation load of 0.001 N was used and 100 indents per specimen were taken. The elastic modulus measured for the Choice composite was

The nanoindentation behaviours of single crystalline silicon samples has gained wide attention in recent years, because of the anomaly effects in the loading curve, caused by the pressure induced phase transformation of silicon. To further enlighten the phenomenon bulk, ion-implanted, single crystalline Si samples have been studied by nanoindentation ...

The Effect of Roughness on Nanoindentation Results [PDF]
Nanoscience and Nanotechnology Letters, 2013 Instrumented Indentation Technique (IIT) or nanoindentation is widely used to measure mechanical properties on nano to macro scales. Due to the simple testing procedure and the continuously increasing sensor sensitivity there exists practically no limitation on application scale and specimen size.
