The State-of-Art Testing and Measurement Instruments   Automatic Micro Contact Angle Meter The micro contact angle meter is specially designed for the pioneers in the micro/nano fields. The instrument is equipped with a unique capillary liquid dispensing system that has an inner diameter of 5-50µm, for making a liquid drop <30µm in size and picoliter in volume. In addition, the instrument comes with high magnification optics for accurately placing and measuring such small drops on micrometer features, and CCD cameras with a high capturing speed of 60 frames per second for studying dynamic characteristics of interaction of micron size liquids with solid surfaces. The technique is sensitive and capable of detecting monolayer molecules. The unmatched instrument capabilities and usefulness for contact angle measurement at microscale have been exemplified through results obtained on fibers, medical guide wires, patterned organic light emitting display and microcircuits. Its advantageous high speed capturing capability is demonstrated by measuring the strong dependency of contact angles on time at millisecond intervals. The recorded feature-rich dynamics of contact angles of micron size drops is deemed valuable for investigating sensitive surface chemistry, vapor evaporation, wettability, and hydrophilicity/hydrophobicity changes at micro/nano scales.   The Full Feature, Multi-technique Nanoindenter    The main unit of a Nanoindentation System   The load-displacement transducer, SPM scanner and top-down optics mounted on a granite structure with X-Y-Z automated stages inside the environmental enclosure Nanoscience and nanotechnology accelerate the proliferation of novel materials and devices possessing small sizes and low dimensions such as nanomaterials and ultra thin films. Mechanical testing and characterization of these materials have exposed challenges to the traditional hardness and tensile testing and measurement tools. Nanoindentation, also referred to as instrumented or depth-sensing indentation, is a promising technology for measuring nanomechanical properties of materials and miniaturized devices. To date, nanoindentation has been expanded to encompass a whole spectrum of testing techniques, well beyond the narrow indication of its name. While quasi-static nanoindentation has been broadly accepted as a method for determination of nanohardness and elastic modulus of materials, dynamic mechanical analysis of visco-elastic materials at nanoscale has seen steadily increasing interest. The nanoscale pulling and compression tests have also become a choice of tests. The NAT Lab nanoindenter is a full-feature, multi-technique nanomechanical and nanotribological test system. It performs closed-loop controlled nanoindentation, nanoscratch, nanowear, nanopulling, nanocompression tests with sub-nanometer and nanoNewton resolutions. Experiments can be conducted at room, elevated or reduced temperature, submerged in liquid, or under humidity control. The in-situ scanning probe microscopy (SPM) capability of the instrument enhances the nanoindentation function by enabling SPM imaging of the surface and positioning the indenter tip with nanometer precision over the feature to be studied. Examples of materials and devices that can be tested include thin films, coatings, nanoparticles, nanowires, bulk material surfaces and interfaces, MEMS, and electronic and biomedical devices.
