Thermal Effects and Sensing

Molecular Dynamics and Interfaces

Spectroscopy and insights in-to thermal effects. Breaking barriers to establish state-of-the-art sensing technology.

In our lab we go across different phases of matter: solids, liquids and gases. We have solids where we do studies in crystals and glass plates. We have looked at thin films. Then we go to liquids; we do dynamics of liquids, measure two-photon fluorescence, two-photon absorption, two-photon cross-sections etc. We have a molecular beam chamber. Also we work in interfaces which are between liquid-liquid, and liquid-solid. The basic idea behind doing this is, it has connection to biology. Another very interesting work is, how long phenomena effecting short term phenomena like temperature. Temperature as all know that is long term phenomena. But we have found that a long term phenomenon has important impact on short term phenomena. The important work in this direction started form the time of Mathies and Shank, where they showed that the ultimate concept of our vision which is in nanoseconds or longer actually starts at femtoseconds. They showed that the primary proton transfer process occurs in less than femtoseconds which is the trigger for the rhodopsin molecules to start the process of optical nerve firing and that finally gives rise to the image. We are interested in seeing how these eventual phenomena are actually connected.

Our work in this field spans decades from (missing reference) to [1,2]

In particular, the lab has generated breakthrough insights into the thermal relaxation process and has gone on to show usage in nano-scale temperature sensing in [3,4,5,6]
