Studying the change of the nanostructure of liquid crystals

The liquid crystals that are used in PC or TV monitors are arrayed regularly in the vertical and horizontal directions owing to a self-assembling mechanism.

This study explores how the regularity of the array changes with heating, using a stearic series compound

information obtained from the liquid crystalsThe large outside ring (below left) shows the information obtained from the liquid crystals (the central ring represents a part of the direct beam from the X-ray source). With 5-second measurements using a two-dimensional CCD, the peak position and the information is obtained on the two-dimensional structure of the sample, such as whether or not the sample is uniform or if it is oriented in a special direction.

By combining highly functional multilayer mirrors, Rigaku's NANO-Viewer enables the user to observe rapidly changing behavior during the melting of liquid crystals. The figure to the right reveals that the liquid crystals are melting while keeping the size of the structure unchanged.

The S-MAX3000 pinhole SAXS camera design is available with a choice of conventional or high brilliance X-ray sources. A 3-meter, fully evacuated camera length provides both high intensity and high resolution. Coupled with a fully integrated 2-dimensional multi-wire proportional counter, the system is capable of making highly sensitive measurements from both isotropic and anisotropic materials. A wide range of sample stage attachments provide maximum flexibility in controlling environmental sample conditions during measurement. Read more...
