• Atomic Force Microscopy (AFM)
Atomic force microscopy (AFM) or scanning force microscopy (SFM) is a very high-resolution type of scanning probe microscopy, with demonstrated resolution on the order of a nanometer, more than 1,000 times better than the optical diffraction limit. The AFM is one of the foremost tools for imaging, measuring, and manipulating matter at the nano-scale. The information is gathered by "feeling" the surface with a mechanical probe. Piezoelectric elements that facilitate tiny but accurate and precise movements on command enable the very precise scanning.
- Simple High-Resolution Imaging
- - Robust image optimization, even on challenging high-resolution sample
- Resolution as good or better than any other imaging modes - Simple High-Resolution Imaging
- - Very low imaging force, here 50pN, limits compression of soft samples
- Imaging remains stable for extended periods because setpoints does not drift - Image Features that Tapping mode can’t
- - Narrow trenches and pits cause problems for Tapping Mode due to excessive damping of the probe oscillation
- Peak Force Tapping is immune to these effects, easily reaching the bottom of these types of difficult features

• Universal Testing MachineUh-I 1000kN
Uh-I 1000kN universal testing machine is the equipment which can apply the compression, tension, and buckling loads to the various types of specimens. We can easily and efficiently test the material properties such as Young’s modulus and Poisson’s ratio of the specimens. We experiment the buckling strength of a circular pipe and the crack propagation of flat plates.
- Instron 5800 series
Instron electromechanical load frames are designed to apply a load to a test specimen via the moving crosshead. A load transducer(load cell) converts the load into an electrical signal that the control system measures and displays. Load cells are interchangeable with others of different capacities. Strain transducers(extensometers) can also be used on these systems to measure strains.

• 3-Dimensional scanner3-Dimensional scanner
3-D Scanner is for isogeometric analysis and optimization. It can create digital 3-D CAD models directly from physical objects in seconds. It is completely scalable and provides industrial grade geometry and color accuracy. Using this CAD model, we can create NURBS model required for isogeometric analysis which enables to integrate the CAD and CAE models. Also this facility can be used for morphing analysis using a level set approach

• Accerlys Material Studio 5.0Accerlys Material Studio 5.0
The Material Studio is the name of commercial software tool for molecular dynamics simulation. We can determine the various properties of nano-scale material, polymer, and catalysist. Three modules, Visualizer, Adsorption locator, Discover are introduced n Oct. 2009. The Visualizer module allows to model the molecular structure which we want to simulate easily and intuitively. Adsorption locator and Discover modules allow not only to consider the molecular structure when the adsorption phenomena occur but also to find the mechanical properties of nano-scale composite material from stochastic analysis. Results from this software can be used to design carbon nano tube structure for the reinforcement of material and to the shape optimization problem of gold nano particles.
