• ) also generate inherent distortions in the image, creating an additional bow in the apparent topography [13]. Some of the early work in the field addresses the need to correct these background distortions appropriately by fitting only the background regions to a polynomial of the correct order [35]. 1-D

Figure 1D adds a second-order polynomial distortion to simulate scanner bow (less than 10 nm over the scan range, which is well within

• fitting, are 2-D polynomial fits. 2-D polynomial fits can be performed by using either the whole figure for the fit, or only certain regions of the image determined by using thresholds. Figure 2 shows a comparison of different processing methods on a standard calibration grating as well as on a lipid

The angle of sample illumination was set to 45°, which is well above the critical angle of total reflection (approx. 43°) at an air–glass interface. Corresponding to the experiment, the wave lengths for illumination and fluorescence emission were set to

• individual twins in the particle. The evolution of multiply twinned morphologies has been traced back to a competition between surface and volume energy contributions, which vary with particle size. This can be understood by means of a phenomenological third order polynomial law which expresses the binding
