3P296 Single bio-molecular fluctuations and molecular activities due to light absorption

Molecular Absorption

Remote sensing (from ground-, airplane-, balloon-, or satellite-based platforms) is a powerful and versatile tool to estimate profiles of atmospheric temperature, trace gases, etc. and has been established as indispensable for research on climate change, stratospheric ozone depletion etc. An essential prerequisite is the accurate and complete knowledge of the absorption properties of the atmosp...

Modeling and Simulation of a Molecular Single-Electron Transistor

In this paper, to understand the concept of coupling, molecule density of states that coupled to the metal electrodes will be explained then, based on this concept, a weak and strong coupling for the molecules attached to the metal electrodes will be described. Capacitance model is used to explore the connection of addition energy with the Electron affinity and the ionization energy of the mole...

Organic and Bio-molecular Chemistry

Giant absorption of light by molecular vibrations on a chip.

Vibrational overtone spectroscopy of molecules is a powerful tool for drawing information on molecular structure and dynamics. It relies on absorption of near infrared radiation (NIR) by molecular vibrations. Here we show the experimental evidence of giant enhancement of the absorption of light in solutions of organic molecules due to the switch from ballistic to diffusive propagation of light ...

Light Scattering and Absorption due to Bacterial Activity in Water

There is a growing class of elementary particle detectors ("Large Water Cerenkov Detectors") which have a body of water (thousands of tons) as a sensitive medium. Particles are detected when they interact with the water and produce Cerenkov light, so detection efficiency relies on the transparency of the water. These detectors are active typically for many years and so biological activity is on...
