Chapter
Fingering Instability of a Spreading Drop
Most studies of the dynamics of wetting have focused on the spreading of pure non-volatile drops on smooth and dry surfaces. For the most part, such spreading processes are well understood, with good agreement be...

Experimental Studies of Hydrogen Notion in Hydrogenated Amorphous Silicon and Germanium
An infrared and secondary ion mass spectrometry study of H diffusion in undoped, rf sputtered multilayered hydrogenated/deuterated amorphous silicon (a-Si:H) and germanium (a-Ge:H) is reported. The results ind...

Effect of Elastic Bending Energy on Emulsification Failure in AOT Microemulsion
Small angle neutron scattering experiments have been carried out to study the phase stability of very dilute water-in-oil AOT microemulsion. At a fixed water to surfactant mole ratio of w=30, we observed a dec...

Chapter
Granular Flow in Hoppers and Tubes
We have studied the effect of gas-grain interaction on the flow of sand for two different experiments. The first experiment deals with the intermittent flow observed in a closed hour-glass. The intermittency r...

Transgenic Ryegrasses(Loliumspp.)
Ryegrasses (Lolium spp.), together with the closely related fescues (Festucaspp.), are of significant value in temperate grasslands (Jauhar 1993). The commercially most important ryegrasses are Italian or annual ...

Microstructure and microhardness in surface-nanocrystalline Al-alloy material
Discussed and analyzed are the surface-nanocrystallization of Al-alloy material manufactured by using the ultrasonic shot peening method. The transmission electron microscope (TEM) is used to examine the micro...
