The Fourier theory of heating is not applicable to the short-pulse type of laser heating due to
the assumptions made in the theory. On the other hand, two-equation and kinetic theory …

The study of heat conduction in situations involving very short times cannot be set about with
the help of Fourier's law. This model which cannot be justified in case of local non …

One of the major differences between electrical and thermal transport in solids is that
electrical conductivities of material vary over 20 orders of magnitude whereas thermal …

The present study considers laser heating of silicon. A three-dimensional form of electron
kinetic theory approach is considered when deriving the governing heat transfer equation …

In the present study, comparisons of electron kinetic theory predictions with results of two-
equation and one-equation models are made. The numerical solutions for all models …

The thermophysical properties and thermal transport characteristics of complex fluids are a
subject of growing interest in a variety of fields ranging from energy to medicine. The …

Non-equilibrium energy transport takes place in solids once the laser pulse duration
reduces to picoseconds or less. It is this energy transfer mechanism that defines the laser …

Porous silicon exhibits unique characteristics, such as quantum confinement, a high surface-
to-volume ratio, and surface and structural disorder, which lead to enhanced optical …

Thin solid films and porous materials with nanometer-scale characteristic dimensions
possess physical properties fundamentally different from those observed at larger length …

Professor Tien pioneered and nurtured the field of micro-and nanoscale heat transfer. With
his method of pushing to extremes in research and his keen physical insights, he started …
