Physical Review B, 1992
Two possible joints between different types of carbon tubules are discussed. Both joints introduce a single pentagon-heptagon pair into the perfect hexagon bonding pattern of the two tubules. These two types of joints can be used to form composite tubules in which every carbon atom is threefold coordinated.

Methodologic as well as conceptual progress during the past decade has made it possible for renal physiologists to “peek” inside the epithelial “black box” of renal tubular function with a greater degree of confidence than ever before. Among the more important developments have been: (1) evolution of the fluid mosaic model of plasma membrane structure (

Are fullerene tubules metallic?
Physical Review Letters, 1992We have calculated the electronic structure of a fullerene tubule using a first-principles, self-consistent, all-electron Gaussian-orbital based local-density-functional approach. Extending these results to a model containing an electron-lattice interaction, we estimate that the mean-field transition temperature from a Peierls-distorted regime to a ...

Neuromuscular Disorders, 2012
Within muscle fibres, tubules appear as microtubules, transverse tubules, and different components of the sarcotubular system, the latter consisting of longitudinal tubules and lateral or terminal sacs which, at special junctional connections, are situated on both sides of transverse tubules forming triads.

Hydrodynamics in the renal tubule
The Bulletin of Mathematical Biophysics, 1965Explicit solutions of the Navier-Stokes equations are presented for axially symmetric slow flow in an infinite cylinder whose walls reabsorb fluid at a rate which varies exponentially with the longitudinal coordinate. Results similar to those of a previous paper which assumed a constant rate of reabsorption are obtained.

Recent fundamental research has revealed the possibility to rationally form supramolecular aggregates. These self-assembled structures range in size from several nanometers (containing a few molecules) to hundreds of microns (containing billions of molecules). The ability to control both the morphology and size of these aggregates through modifications
