AFM image gallery added

 I have created an AFM Image Gallery section. There is currently one gallery, called " My AFM Images". There are images that I have measured of a variety of samples there, from polymers to nanoparticles, to cells. I will be adding some more images soon. The images serve as a way to illustrate the power and flexibility of AFM imaging. If you register as a user of the web site ("user menu" on the left") You can create your own galleries, and fill them with your own images. This can be anice way o promote your work, feel free to include a link to your web pages or publications. Please note that this section is for AFM images only! Anthing else will be removed. You can also vote for your favourite images within the galleries. I look forward to seeing some exciting and beautiful images!

 Chapter 6: AFM Artifacts
In this chapter, common problems in AFM images are discussed. Some of these artifacts are inherent to the technique, and are impossible to avoid. Others depend on the particular instrument used, or the properties of the probe selected. Some are due to imaging parameters, and can be easily avoided. In each section, the artefact is described, the reason for the appearance of the artifact is discussed, and steps that can be taken to avoid it are given. In nearly all cases, there is an illustration of the artefact in a real AFM image.
Take this test to see if you can recognise and understand the reason of, common AFM artifacts, and realise how they can be avoided.
Questions
1. Which of these two images was taken with a sharp probe?

Measuring AFM Images
This chapter explains how to measure AFM images properly.The topics covered include sample preparation, preparing the microscope for imaging, including optical alignment, optimisation of imaging parameters, and acquiring high-resolution images. There are sections covering contact mode, intermittent contact, lateral force microscopy and acquiring other signals, and measuring force curves.
The quiz will check if you remember important concepts, and avoid common mistakes when acquiring data.

Chapter 5: Processing AFM Images
This chapter covers how to process, display and analyse AFM data. It mostly covers manipulation of topographic data, but some of these techniques apply to other data as well. Since the best data still needs the best treatment to extract desired results, it is important that AFM users are aware of the benefits (and pitfalls), of data processing and analysis techniques.
After reading the chapter, it is advisable to take this test since it will ensure that you are aware of the most important concepts in correct data treatment.

AFM Modes
Chapter 3 is all about the different AFM modes and experiments that can be carried out. The variety of different imaging methods, and the ability to use other modes to detect different properties of the sample, are the real reason for the widespread use of AFM.
In this chapter, the book covers: Topographic modes: contact mode and oscillating modes. Then it moves onto non-topographic modes, including force spectroscopy, Nanoindentation, mechanical property imaging, lateral force microscopy, phase imaging, other dynamic modes, magnetic force microscopy, EFM and SKPM, electrochemical AFM, and thermal modes.Finally, it also covers methods that allow surface modification.
