This webinar introduces the polymer rheological measurement capabilities of the new AFM-nDMA mode, which for the first time provides viscoelastic measurements that match bulk dynamic mechanical analysis (DMA) over the entire frequency range.
Since the mechanical properties of polymers are time dependent, full understanding requires measurements over a range of frequencies and temperatures. Where DMA is well suited for measurements on bulk samples, it is less adept at characterizing microscopic domains within heterogeneous polymer material. Established AFM methods, either provide property maps at discrete frequencies orders of magnitude higher than bulk measurements (e.g., TappingMode and contact resonance), making comparisons difficult, or struggle with such intrinsic mechanical properties as loss tangent and storage modulus (e.g., force spectroscopy and PeakForce Tapping).

SANTA BARBARA, California – November 28, 2018 – Bruker today announced the release of the Dimension XR™ family of scanning probe microscopes (SPMs). These new systems incorporate major AFM innovations, including Bruker’s proprietary and exclusive DataCube nanoelectrical modes, AFM-SECM for energy research, and the new AFM-nDMA mode, which for the first time correlates polymer nanomechanics to bulk dynamic mechanical analysis (DMA). Building on two of the world’s most utilized AFM platforms in scientific publications, the Icon® and FastScan®, Dimension XR SPMs are available in three configurations optimized for nanomechanics, nanoelectrical, and nanoelectrochemical applications. These systems significantly expand researchers’ ability to quantify material properties at the nanoscale in air, fluids, electrical, and chemically reactive environments.
“The new Dimension XR systems are the culmination of years of innovations to provide quantitative and easy-to-use nanomechanical, nanoelectrical, and nanoelectrochemical characterization,” explained David V. Rossi, Executive Vice President and General Manager of Bruker’s AFM business. “Our goal is to make these first and only capabilities widely available to the research community, enabling their breakthrough AFM discoveries with new nanoscale information.”
Providing First and Only AFM Viscoelastic Measurements that Match Bulk DMA
BOSTON, Massachusetts – November 27, 2018 – At the 2018 MRS Fall Meeting & Exhibit, Bruker today announced the release of the AFM-nDMA™ mode for Dimension® atomic force microscopes (AFMs). Going beyond the quantitative elastic modulus mapping enabled by Bruker’s exclusive PeakForce QNM® mode, AFM-nDMA provides first and only nanoscale viscoelastic measurements that match bulk dynamic mechanical analysis (DMA) over the entire frequency range typical in bulk rheological measurements. Enabled by proprietary algorithms, AFM-nDMA works directly at rheological frequencies, quantifies preload and adhesion, and comes with absolute calibration. As a result, AFM-nDMA generates entire master curves of storage modulus, loss modulus, and loss tangent, including analysis for activation energy, thus vastly expanding the AFM market by providing polymer rheology at the nanoscale.
“Bruker’s AFM-nDMA is the first commercial solution for quantifying viscoelasticity at the spatial scales of AFM,” said Dr. Ken Nakajima, Professor of Polymer Physics at Tokyo Institute of Technology. “Having pioneered nanoscale rheological measurements, I am very excited to see this important capability become widely available.”
“We can now quantify local viscoelasticity at relevant frequencies and length scales that relate nanoscale properties to bulk performance,” added Greg Meyers, Ph.D., Dow Chemical Core R&D Fellow. “This addresses a significant unmet need for industrial polymer characterization.”
“AFM-nDMA reflects our long-standing commitment to provide quantitative and easy-to-use nanomechanical characterization,” explained David V. Rossi, Executive Vice President and General Manager of Bruker’s AFM business. “From the invention of TappingModeTM to PeakForce Tapping® and now AFM-nDMA, we have consistently led this charge, and we are very eager to see the use of atomic force microscopy growing with quantitative viscoelastic characterization.”
October 25, 2018 ─ Bruker has recently introduced new and expanded probe families to address AFM industry needs.
PeakForce Deep Trench
Bruker’s new PeakForce Deep Trench (PFDT) series of probes is engineered to provide accurate depth metrology and imaging on the most challenging structures encountered on semiconductor samples and optics, including trenches and pits with aggressive aspect ratios and depths of more than 100nm.
Specifically designed for Dimension Icon, this probe series leverages PeakForce Tapping technology. PeakForce is well known to be ideal for aggressive geometries, such as deep and narrow trenches, because it avoids the air damping and sticking effects that plague approaches based on resonant modes such as Tapping or non-contact. The cantilever shape, spring constant, and resonance frequency of these probes are highly optimized for PeakForce Tapping, and the spike angle is tilt corrected for Dimension Icon. The result is repeatable, accurate metrology with high throughput and long tip life.
Bruker is also introducing a range of probes for contact resonance. All of these probes feature a wear-resistant, conductive diamond coating for highest repeatability and resolution. On a Dimension Icon with FASTForce Volume Contact Resonance, these probes have been shown to provide many dozens of images with no measurable wear or change in nanomechanical values. These probes also employ Bruker’s V2 process for the most consistent tip and cantilever shape, further enhancing measurement consistency.
We have vastly expanded our offering of Adama Innovations diamond probes. Our range now includes sharp and supersharp apex diamond tips for high resolution electrical applications, intermediate radius cone shape tips with outstanding consistency, wide angle tips for highest load mechanical applications, and high aspect ratio pillar tips for the most challenging geometries. All tips feature strong wear resistance, allowing for constant contact size and resolution during long term measurements.
World-Leading Graphene Research Facility Purchases Multiple Bruker AFMs
BILLERICA, Mass. – April 6, 2015 – Bruker Corporation (NASDAQ: BRKR) today announced an official partnership with the University of Manchester’s National Graphene Institute (NGI), joining a select list of industrial collaborators. This partnership follows NGI’s purchase of two additional atomic force microscopes (AFMs) from Bruker, a Dimension FastScan® and a Dimension Icon®. These systems join five other Bruker AFMs at the facility for research into the nanofabrication and nanoscale properties of graphene. As part of this partnership, Bruker will partially sponsor a Ph.D. student working on novel scanning probe microscopy (SPM) techniques to characterize graphene and 2D materials.
Graphene, the world’s thinnest, strongest and most conductive material, was first isolated and characterized at The University of Manchester by Sir Andre Geim and Sir Kostya Novoselov, who were awarded the Nobel Prize for Physics in 2010 for their research. This transparent, one-atom thick flat sheet of carbon has the potential to revolutionize technology, from smartphones and ultrafast broadband to drug delivery and computer chips. AFMs have demonstrated spatial resolution of less than a nanometer, and enable scientists developing materials such as graphene to understand critical mechanical, electrical, and chemical properties at the atomic scale.
“Our Bruker AFMs are anticipated to provide important new insights into nanoscale variations of graphene conductivity and work function,” said Nobel Prize winner Professor Novoselov. “Coupled with simultaneous quantitative mapping of mechanical properties, enabled by Bruker’s exclusive PeakForce Tapping®, NGI researchers hope to uncover new information that will ultimately optimize the performance of graphene-based materials and devices.”
“We are pleased that the National Graphene Institute continues to rely on our proprietary technology for its new world-class research facility, bringing their total now to seven Bruker systems,” added Paul Scagnetti, Ph.D., President of Bruker’s Nano Surfaces Division. He continued: “We are also gratified to be a part of the UK-wide Centre for Doctoral Training, where our unique AFM technologies will enable the sponsored Ph.D. student to learn even more about the physical and electrical properties of 2D materials under Professor Novoselov.”
