SWNT/polymer composites could also be made by a two-step fabrication process. For example, SWNT films were first fabricated on glass slides via Mayer rod coating, and then polymers such as PVA, Nafion and polyvinylidenefluoride (PVDF) were infiltrated into SWNT networks. As the polymer occupied the empty space between the nanotubes, a freestanding... 

Another test incorporates the use of a Mayer Rod, a 6 wire round rod. This test is used for flat, sheet polyolefins. The test procedure is as follows ... 

Place the Mayer rod on the polyolefin surface near and lengthwise to the series of drops. Carefully pull down the Mayer rod into the solution. 

With a smooth continuous movement, move the Mayer rod so as to lay down a thin continuous layer of liquid. Several solutions can be applied at the same time for a simultaneous drawdown as long as there is no mixing of the different solutions. 

Observe the film(s) until the continuous film breaks into droplets. Record which solution comes nearest to wetting (laying flat) on the substrate surface for a period of 2 seconds. Repeat this test until a solution is used that meets the 2 second standard. Carefully clean and dry the Mayer rod between each test. 

A second product is the ICE Solid-State Model Kit, developed by L. A. Mayer and G. C. Lisensky, which makes it possible to build extended three-dimensional structures Using a base with holes, templates for some 60 different structures, rods, and four sizes of spheres in radius ratios, common crystal structures can be assembled in a matter of minutes (3). Furthermore, many structures can be assembled from different perspectives by teams of students For example, the cubic NaCl unit cell can be assembled with its orientation on the face of the cube or on the body diagonal. Natural cleavage planes can be found with the kit Lifting one sphere will separate atomic planes from one another. (Contact ICE for ordering information.)... 

We present how to treat the polarization effect on the static and dynamic properties in molten lithium iodide (Lil). Iodide anion has the biggest polarizability among all the halogen anions and lithium cation has the smallest polarizability among all the alkaline metal cations. The mass ratio of I to Li is 18.3 and the ion size ratio is 3.6, so we expect the most drastic characteristic motion of ions is observed. The softness of the iodide ion was examined by modifying the repulsive term in the Born-Mayer-Huggins type potential function in the previous workL In the present work we consider the polarizability of iodide ion with the dipole rod method in which the dipole rod is put at the center of mass and we solve the Euler-Lagrange equation. This method is one type of Car-Parrinello method. 

The theory for the analysis of meniscus behaviour in uniform tubes was first given by Mayer and Stowe 1 but it was presented as a solution for pores defined by spheres. Princen applied the theory to pores with longitudinal symmetry such as those made up of parallel rods (used as a model for bundles of fibres). The theory, referred to here as the MS-P theory, is straightforward in concept but has profound implications. 

From a numerical standpoint the Ree-Hoover expansion is far better to work with than the Mayer expansion. There are two reasons for this. First, the inserted / functions act as additional constraints which render each integrand nonzero only over a much more limited region of configuration space. (It isn t hard to see that each Ree-Hoover integral corresponds to a different region of configuration space, and that some of those regions will be very small. For hard rods, disks. 

We know that Va is inversely proportional to d, whereas Vr decreases exponentially with the distance 2d. Thus, at short and long distances of d, Va becomes larger than Vr, but at intermediate distances the two particles repel each other strongly due to the repulsion of Bom and Mayer. Thus, Vt has two minima, as shown in Fig. 7.7 a deep one at a short interparticle distance and a shallow one at a relatively long interparticle distance. Coagulation takes place at the first deep minimum. The secondary minimum plays an important role for plate- or rod-like particles that have a wide interparticle contact area. However, because the second minimum is relatively shallow, the coagulation induced by it is easily broken by an external force. This effect is closely related to rheological phenomena of colloidal suspensions.
