Hollow mesoporous silica fibers: tubules by coils of tubules
Physical Chemistry Chemical Physics, 2001Hollow mesoporous silica fibers have been synthesized under acidic conditions in a two-phase static system. The fibers always have a circular internal architecture with hexagonally arranged channels running perpendicularly around the fiber axis. The inner radius of the hollow fibers is variable and the fibers are connected with solid fibers without ...

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.

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 (

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.

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 ...

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

The osmotic permeability of a tubule wall
Bulletin of Mathematical Biology, 1988The influence of unstirred layers in osmotic experiments designed to measure the osmotic permeability of a tubule wall is considered. Results are given in the form of a set of graphs whose axes are closely related to observed and known experimental parameters. These enable osmotic permeability values to be obtained which are closer to the true values.
