Title: Mass-resolved circular dichroism spectroscopy of cold, isolated chiral molecules
In chemistry, chiral molecules cannot be superposed on its mirror image. They have identical physical and chemical properties, but only absorption coefficients differ for left- and right-handed circularly polarized light, which is called CD. CD spectroscopy has been extensively used to investigate the structures and structural changes of chiral compounds. Most of CD have been measured in solution where molecules exist in many conformations, and thus the values obtained represent averaged CD values. By contrast, CD spectroscopy of chiral molecules in the gas phase can distinguish specific conformers of a chiral molecule. Here, I will report the mass-resolved CD spectra of chiral molecules and their clusters in the gas phase using circularly polarized laser pulses, which were generated by using the photoelastic modulator and nanosecond laser system. The CD spectra exhibited well-resolved bands which were specific for the conformations and vibrational modes of each enantiomer. Moreover, the CD signs and magnitudes of the chiral molecules were very sensitive to their conformations.

Title: Analysis of economic growth-industrial activities-industrial hazardous waste nexus in South Korea
Industrial hazardous waste (IHW) has been a fatal negative impact on the environment and humans. It also caused social problems, such as waste transactions between countries in unequal status from developed countries to less developed countries. To prevent this, the Basel Convention has been signed to regulate the transboundary movements and trade of IHW. This research have firstly modeled extended waste input-output table (EWIOT) for IHW of South Korea. Using this modeled EWIOT. I have analyzed the characteristics of IHW generation based on the industrial ecological concept by modifying IPAT equation and LMDI method, identifying the IHW footprint in sector level in terms of supply and demand and the factors affecting IHW increase or decrease among final demand change factors, import substitution factors, and production technology factors. The results of this research are expected to contribute to the basic research of establishing a rational waste policy that reflects the characteristics of each industry by quantitatively evaluating the generation and management of waste.
