Tryptophan octyl ester (TOE) represents an important model for membrane-bound tryptophan residues. In this article, we have explored the effect of sphere-to-rod transition of sodium dodecyl sulfate micelles on the dynamics of the membrane-bound tryptophan analogue, TOE, utilizing a combination of fluorescence spectroscopic approaches which include red edge excitation shift (REES). Our results s...

For mixtures of hard spheres and hard spherocylinders of large aspect ratio a recently proposed density functional theory is extended to incorporate effects due to nonvanishing rod thickness. This is accomplished by introducing several new geometric weight functions into the framework. We demonstrate explicitly how these weight functions recover the sphere-rod Mayer bond.

In this study we have synthesized ZnO nanoparticles of rod-like, sphere-like and flower-like structure in solvothermal route by using different capping agent. With the help of XRD data, using Shearer’s equation the average particle size of different morphologies were calculated as 86, 57 and 26 nm for flower-like, sphere-like and rod-like ZnO respectively. The direct band gap energies of the na...

We study the structure of stationary solutions to the Doi-Onsager equation with Maier-Saupe potential on the sphere, which arises in the modelling of rigid rod-like molecules of polymers. The stationary solutions are shown to be necessarily a set of axially symmetric functions, and a complete classification of parameters for phase transitions to these stationary solutions is obtained. It is sho...

We study Onsager’s model of nematic phase transitions with orientation parameter on a sphere. We consider two interaction potentials: the antisymmetric (with respect to orientation inversion) dipolar potential and symmetric Maier-Saupe potential. We obtain a complete classification and explicit expressions of all critical points, analyze their stability, and construct the corresponding bifurcat...

Mesoporous silica nanomaterials of different shapes (film, platelet, sphere, rod) were synthesized simply by tuning the mole ratio of dual cationic surfactant templates, cetyltrimethylammonium bromide (CTAB) and tetrabutylammonium iodine (TBAI). The film showed the most potent antibacterial activity against mycobacteria.

Lightning rod is widely used in lightning protection systems. It is of practical interest to analyze the protective performance of a lightning rod taking into consideration some stochastic behaviors of the lightning process. The effectiveness of a single lightning rod is investigated in this paper using a fractal growth approach based on dielectric breakdwon model (DBM). The effective intercept...
