Advanced In-Situ Nanomechanical Test Instrument

Bruker Nanosurfaces has announced the release of the Hysitron PI 89 SEM PicoIndenter, which provides nanomechanical testing capabilities inside a scanning electron miroscopy (SEM) at higher loads and in more extreme environments than previously possible. This will benefit researchers' understanding of the deformation mechanisms of high-strength materials.

 

The PI 89 SEM Picoindenter is the first in-situ instrument with two rotation and tllt stage configuations. This enables flexible sample positioning toward the electron column for top-dwn imaging, tilting toward the FIB column for milling, spindle rotation for crystallographic alignment, and compatibiltiy with a wide range of detectors to enable structure-property correlation of complex materials.

Benchtop 3D Optical Profilometers

Bruker has released the next-generation benchtop ContourX 3D Optical Profilometers. The white light interferometry (WLI) platform features Bruker's new USI mode - a universal scanning mode that automatically determines the optimal measurement parameters for best metrology restuls. Additionally, a 5MP camera and new stage design significantly boosts large-area stitching, allowing for the collection of 1000 high-resolution stitched fields. This combination of features and capabilities enables greater convenience and productivity in a host of demanding research and industrial aplications ranging from studying novel material structures and characterising manufactured components for medical, automotive and aerospace.

Webinar : Cryogenic Sensor Installation Techniques

Friday 19 June, 12am, AEST

REGISTER

Interested in knowing more about how to correctly install a sensor in a cryogenic application and to avoid common installation errors ? Then be sure to join this webinar presented by Dr Scott Courts, Lake Shore Senior Scientist/Metrologist.

This webinar will cover helpful, practical tips on how to choose the right type of sensor and packaging for a specific application and then summarise best practices for minimising installation errors and ensuring superior thermalisation in a cryogenic application.

Topics will include:

  • Considerations for choosing a sensor (including resistance to magnetic fields, ioning radiation, UHV and others)
  • The role of packaging and adapters for shielding, mounting, stability and optical thermal contact
  • Considerations for sensor installation (placement, mounting method, materials, electrical connections, heat sinking, thermal contact medium, etc)
  • A look at the choices for fastening materials, wire leads, thermal mediums and adhesives

AFM-based Nanoscale DMA

The development of heterogeneous materials like polymer composites, blends and multilayers are of considerable importance in the chemicals industry. Bulk viscoelastic measurements are routine in establishing structure-property relationship for these materials. However, materials R&D often produces composites that contain nano-sized portions that do not exist in the bulk or that have properties influenced by the proximity of other components. A quantitative means of measuring the viscoelastic properties of such mterials at the nanoscale has been a long-standing and elusive goal for atomic force microscopy (AFM). While AFM has the sensitivity and resolution needed to do the measurement, traditional AFM-based approaches are hampered by difficult calibration, poorly defined measurement frequency, and inadequate modeling of the tip-sample interation.

 

Now, with the development of the AFM-nDMA mode from Bruker, these pitfalls can be avoided and the frequency and temperature depedence of viscoelastic properties in rheologically relevant ranges can be directly measured with 10nm spatial resolution. Read more or download the application note.
