Abstract This work shows that a soft, thin film comprising randomly aligned carbon nanotubes (CNTs) can reduce surface wear more effectively than homogeneous because of enhanced elastic recoverability and contact stress relief originating from its mesh structure. To investigate the characteristics structure compared to those film, multi-walled CNTs (MWCNTs) diamond-like (DLC) films were prepare...

In this paper a method is presented for torsional analysis of non-homogeneous tubes with arbitrarily shaped cross-sections. A previously presented method based on Bredt’s theory is extended to achieve formulas for torsional analysis. Shear modulus varies through the thickness according to a power law distribution. To validate the accuracy of the presented formulas for angle of twist and shear s...

We perform Brownian dynamics simulations to study the gelation of suspensions of attractive, rod-like particles. We show that in detail the rod-rod surface interactions can dramatically affect the dynamics of gelation and the structure and mechanics of the networks that form. If the attraction between the rods is perfectly smooth along their length, they will collapse into compact bundles. If t...

This paper presents a family of Runge{Kutta type integration schemes of arbitrarily high order for diierential equations evolving on manifolds. We prove that any classical Runge{Kutta method can be turned into an invariant method of the same order on a general homogeneous manifold, and present a family of algorithms that are relatively simple to implement.

Physiol. 219(2) : 497-502. 1970.-Rates of conversion of blood glycerol carbon to blood glucose carbon, a process carried out by the liver, were measured in unanesthetized dogs in the postabsorptive state. The calculation of the rates required knowledge of the separate rates of gluco...
