Drinks and Appetizers will be provided.

Please RSVP for the reception by emailing Ben Ellefson 
at  Bellefson@phi.com  by October 19 if you’ll be able to attend. 

For the characterization of polymers and organic-coated surfaces, the combination of two surface sensitive techniques – X-ray Photoelectron Spectroscopy (XPS) and Time-of-Flight Secondary Ion Mass Spectrometry (TOF-SIMS) can be extremely powerful.  XPS provides quantitative analysis and short-range bonding chemistry from elements on the outermost surface while TOF-SIMS can provide the molecular information needed to positively identify organic species and the spatial resolution needed to show their lateral distributions on the sample surface.  This presentation will discuss the complementary attributes of XPS and TOF-SIMS and demonstrate how combining the two is essential to more fully understand organic surfaces.

We look forward to seeing you there!

Oxford Instruments New Application Note: Video-Rate AFM Opens New Research Possibilities into Surfactant Behavior at Solid-Liquid Interfaces

Learn How Video-rate AFM can image surfactant micelle dynamics

Opens new research possibilities into surfactant behavior at solid-liquid interfaces

application note about using atomic force microscopy to study surfactant dynamics at solid-liquid interfaces

(Free download, compliments of Asylum Research, the Technology Leader in Atomic Force Microscopy)

Download the application note to learn:

  • Introduction to the self-assembly of surfactant micelles at solid-liquid interfaces
  • Challenges associated with characterizing the dynamic behavior of these systems
  • New capability provided by video-rate AFM to visualize these dynamics
  • Several example datasets and links to the full movies (see below)



Watch the Full Movies From the Application Note

Figure 2: Video captured at 5.8 fps (173 ms per frame), showing clearly the rows of CTAB hemimicelles on the HOPG surface and the orientation of the domain boundaries. Tapping mode phase data is shown here for optimum contrast. The video plays back at 23.2 fps (i.e. 4× the acquisition rate). 


Figure 3: Video captured at 0.48 fps (250 Hz line rate) showing two CTAB grains of opposite row orientation (upper-left and lower-right) bounded on the left and right by two grains with parallel orientation. Over time, the two grains narrow at their boundary, eventually separating and drifting apart while the adjacent grains on the left and right merge together. Note the three different row orientations, corresponding to the three directions perpendicular to the HOPG symmetry axes. Video is shown at a playback speed of 1.92 frames per second (i.e. 4× the acquisition rate).
Figure 4: Video captured at 0.95 fps (250 Hz line rate) showing the spontaneous formation of a narrow CTAB grain along the boundary of two orientation domains (upper left). The grain continues to grow for about 20 s until a broader grain in the same orientation begins to emerge behind it. This new grain continues to grow and push the smaller grain out of the field of view. The video plays back at 3.8 fps (i.e. 4× the acquisition rate). Figure 5: The video here was acquired at 0.95 fps (250 Hz line rate). Images in the application note highlight two examples, both of which show small features that seem to absorb into surrounding grains. The process appears analogous to Ostwald ripening, except in this two-dimensional system instead of a bulk dispersion. In both cases, the feature appears with higher phase contrast and appears less structured than the surrounding hemimicelles. The video plays back at 3.8 frames per second (i.e. 4× the acquisition rate).

The movies about were taken using the Cypher VRS Video-Rate AFM

The Cypher VRS AFM is the first and only full-featured video-rate AFM. Finally, researchers can measure nanoscale dynamic processes at video-rate speeds with all of the resolution, versatility, and ease of use that are the hallmarks of an Asylum Research Cypher AFM.

  • High resolution video-rate imaging at up to 625 lines per second
  • Exceptional ease of use—even at 10 frames per second
  • Full range of modes and accessories—all the capabilities of Cypher ES at normal scan speeds

New Asylum Research AFM Accessory Enables Advanced Magnetics Research Under Both In-Plane and Out-of-Plane Applied Magnetic Fields

July 24, 2018 (Santa Barbara, CA) Understanding and characterizing magnetic properties at the nanoscale is one of the key challenges in developing next-generation data storage and logic elements.  The new Variable Field Module (VFM4) accessory for Asylum Research MFP-3D Atomic Force Microscopes (AFMs) enables measurements under applied in-plane and out-of-plane magnetic fields in order to better understand their effects on nanoscale magnetic domain structure. The VFM4 is capable of applying either an adjustable in-plane (±8000 G ) or out-of-plane (±1200 G) magnetic field to a sample and offers ~1 G field resolution. Researchers can learn more about the VFM4 and see recent results at http://afm.oxinst.com/VFM4.

“This new combination of capabilities has allowed one customer at a national synchrotron facility to use AFM for research that was previously only possible with very costly and time-consuming scanning x-ray transmission microscopy (SXTM),” said Dr. Maarten Rutgers, Director of New Product Introduction. “No other AFM commercial solution offers the same capabilities, versatility, and ease of use for magnetics research. While the VFM has traditionally been used for magnetic force microscopy experiments, it can also be used with techniques like conductive AFM (CAFM) and on a wide range of diverse samples including piezoelectric and ferroelectric materials.”

The VFM4 easily attaches to most Asylum Research MFP-3D AFMs and includes replaceable pole tips to quickly adapt between in-plane and out-of-plane configurations. It maintains a steady magnetic field with rare-earth magnets that produce no heat, thermal drift, or mechanical vibration. For experiments where both an applied magnetic field and a high tip-sample voltage bias are required, there is an optional high-voltage kit to adapt the VFM4 for safe application of voltages up to ±220 Volts.
