Learn New AFM Techniques That Can Transform Your Research!

Scientific Atomic Force Microscopy e-Seminars

 

A new company built upon a world of experience! Agilent Technologies' renowned former Electronic Measurement Group is now Keysight Technologies, Inc.

 

These special 60-minute scientific seminars are free, but the knowledge they'll provide is invaluable. Proudly hosted by Keysight Technologies, Inc., each of this fall's four live events will focus on essential elements of advanced atomic force microscopy (AFM) techniques, technologies, and applications.

 

 

Keysight senior application scientist Dr. Song Xu has created these upcoming presentations as a means of sharing what he considers to be must-have information about some of the very latest approaches to AFM. All online attendees are welcome to interact directly with Dr. Xu during open Q&A.

Date:                    October 14, 201411:00 a.m. (New York)

 

Lecturer:            Song Xu, Ph.D. (Keysight Technologies)

 

Title:                    Quantitative Analysis of AFM Data

 

A wide range of quantitative information can be obtained by applying mathematical processes to AFM data. In this seminar, we will discuss the following topics: (1) the mathematical basics of smoothness/roughness measurement; (2) how to measure the size of a single nanoparticle, nanotube, or molecule; (3) how to measure the height of a single atomic/crystal step around a not-so-flat sample area; (4) the basics of measuring the texture orientation of an image; (5) how to measure the coverage % of a sub-monolayer; (6) how to obtain statistics around the size measurement of hundreds of nanoparticles in a single image; (7) how to measure the size of a large bio-sample such as bacteria or a cell; and (8) the advanced topics of grain-, particle-, and texture-automated analysis using commercial data processing software. We will not only cover the methods used to obtain various quantitative calculations but also discuss possible data distortion caused by incorrect analysis. Actual data examples will be presented with full details, including imaging modes, cantilever recommendations, and imaging parameters.

 

Date:                    October 29, 201411:00 a.m. (New York)

 

Lecturer:            Song Xu, Ph.D. (Keysight Technologies)

 

Title:                    Study of Mechanical Properties Using AFM

 

Basic AFM imaging modes provide high-resolution topographic information of samples. However, the AFM cantilever is a very sensitive force sensor that can be used to study the mechanical properties of a sample and obtain information beyond topography. In this seminar, we will discuss the following topics: (1) the basics of an AFM-based force curve in contact mode; (2) what we can learn from such a force curve; (3) lateral force imaging (chemical force) and the kind of information we can obtain from this imaging mode; (4) phase imaging in AC mode and what we can learn about a sample's mechanical properties from this imaging channel; (5) AFM-based nanoindentation to obtain sample hardness and modulus; (6) scratching tests using an AFM tip and what we can learn from this technique; and (7) combining mechanical testing with electrical testing to study the surface of a stainless steel sample. More topics can be added by audience request.

 

Date:                    November 11, 201411:00 a.m. (New York)

 

Lecturer:            Song Xu, Ph.D. (Keysight Technologies)

 

Title:                    Design & Develop Your Own Experimental Ideas in AFM Applications

 

 
AFM and scanning tunneling microscopy (STM) technologies are very powerful and versatile research tools for physics, materials science, chemistry, biology, and many other different areas. When using any type of instrument as a research tool, however, the original setup often needs to be modified. In this seminar, we will discuss the following topics: (1) how to design and build sample holders that can hold a difficult sample, such as small beads, soft films, thin fibers, soft biological tissues, or curved soft samples; (2) design ideas for sample side modulation, such as mechanical modulation for mechanical property testing, or illumination for photovoltaic measurement; (3) fluid cells with requirements such as extra large volume, extra small volume, extra heating, cooling, and so forth; (4) special sample cells for biological samples that require sterilization, contain no metal parts, and are very easy to assemble; and (5) insulated electrical circuitry situated very near the sample to collect small electrical signals. As the date of this seminar approaches, we may add new topics based on audience requests.

 

 

Date:                    December 3, 201411:00 a.m. (New York)

 

Lecturer:            Song Xu, Ph.D. (Keysight Technologies)

 

Title:                    Desktop Manufacturing & Its Application to AFM Research

 

 
There is a revolution emerging right now, desktop manufacturing, which may bring new ideas and capabilities to your research experiments. In this seminar, we will discuss the basics of computer-aided design, computer-aided manufacturing, and computer-controlled machines (such as 3D printing, 3D milling machining, and computer-controlled laser cutting) to solve your AFM-related research challenges and create projects for your unique research experiments. We will present examples associated with the following discussion topics: (1) the design and fabrication of sample holders for samples with complicated shapes; (2) the design and fabrication of an electrochemistry cell that holds single-crystal samples of different sizes and shapes; (3) a liquid cell designed for imaging a fiber-type sample in liquid; (4) combining an electrochemistry cell with a cooling and heating channel; and (5) a self-pop sample holder for lithium battery research. More topics may be added based on requests from the audience.
