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.
High Resolution AFM Imaging
The NanoWizard 4 XP Nanoscience atomic force microscope delivers atomic resolution and a large scan range of 100µm in one system. It enables fast scanning with rates of up to 150lines/sec and seamless integration with advanced optical techniques. A wide range of modes and accessories for environmental control, mapping of nanomechanical, electrical, magnetic or thermal properties, makes it the most flexible system available on the market today.
Webinar : Cryogenic Sensor Installation Techniques
Friday 19 June, 12am, AEST
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.
