![]() ![]() The Landau-de Gennes theory is used to calculate the order parameter changes in the medium. ![]() It is surprising that sp3 bonded carbon was found to exist not only as cubic crystals but also as hexagonal crystals 20. Also, the numerical density definition is renewed in the presence of nanotubes. It is shown that in the nematic phase the flexoelectric coefficients increase along with the increase of the coupling strength and temperature. The enhancement in flexoelectric coefficients is more significant in hard anchoring conditions than in the weak anchoring case. The flexoelectric coefficients increase up to 5-fold is calculated near the phase transition temperature, which is in good accordance with the experimental reported data.

Chlorosulfonic acid (CSA) is known to be an ideal solvent for CNTs, spontaneously dissolving them without compromising their properties. At typical processing concentrations, CNTs form liquid crystals in CSA however, the morphology of these phases and their concentration dependence are only qualitatively understood. Here, we use small-angle neutron scattering (SANS), combined with polarized light microscopy and cryogenic transmission electron microscopy to study solution morphology over a range of concentrations and two different CNT lengths. Our results show that at the highest concentration studied the long CNTs form a highly ordered fully nematic phase, while short CNTs remain in a biphasic regime. Upon dilution, long CNTs undergo a 2D lattice expansion, whereas short CNTs seem to have an intermediate expansion between 2D and 3D probably due to the biphasic nature of the system.

![]() ![]() Topaz Adjust 5.0.1 - plug-in plugin Adobe Photoshop for processing digital images. Technology used in this program is very accurate and can cope with complicated pictures parts, such as shadows, transparency, small parts, hair, leaves, etc. All it takes is a few minutes, highlight the desired object is a special plug-in brush: green brush, you should choose an area that should remain unchanged blue tassel, you should circle the contours of the object plug-in for processing, which automatically separates the object from the background, red brush you excrete the background of your image. ![]() The plugin uses a unique technology of the new generation, which allows the automatic mode most accurately cut the object and apply it to another picture. Separated at the same object can be used as a separate layer for a smooth integration with other images. Topaz ReMask 4.0.0 - great plugin for Adobe Photoshop, allows you to quickly and easily distinguish objects from backgrounds. Plug-in opens up many new opportunities for professional photographers and digital artists. In addition, the use of Topaz Simplify, you can create thumbnails of images with simulated pencil sketch. Using their own settings and adjustments you can keep them in their own settings to use them in the next image. To achieve results quickly, you can use ready-made presets. With Topaz Simplify, you can create stunning images with simulated oil paints, watercolors, pencil and wood. Topaz Simplify 4.1.1 - plug-in for Adobe Photoshop to create masterpieces of art from any of the pictures. Unlike other similar programs, in which the blurred image details, DeNoise analysis of all image processing, and, therefore, eliminates the noise while preserving the conservation of important detail of the image. ![]() In Topaz DeNoise 3, a completely new approach to noise reduction, which differs from other methods to date. The plugin uses the latest technology of high-quality noise in digital photos, saving more image details. Topaz DeNoise 5.1.0 - plug-in to remove noise in the photo in Adobe Photoshop. It provides unlimited opportunities for both beginners and professional photographers who can provide high quality and clarity of the image with just one connector. The essence of this plugin is as follows: Topaz Detail share your photos in three parts — small parts, medium and large items — and gives full control of any type. In addition, the use of Topaz parts, you can increase or decrease the sharpness of images, convert images to grayscale with full control of tonal range. Topaz Detail 3.2.0 - plug-in for Adobe Photoshop to create the HDR-images without the appearance of luminous halos. ![]() ![]() All advisory and assistance services are classified in one of the following definitional subdivisions: In rendering the foregoing services, outputs may take the form of information, advice, opinions, alternatives, analyses, evaluations, recommendations, training and the day-to- day aid of support personnel needed for the successful performance of ongoing Federal operations.
