Tecrübe

Researcher

Dec 2013 - Dec 2017 (4 years)

I carried out research to generate particle species that important to atmospheric and extraterrestrial aerosols and particles . The techniques involve using champers to control temperature, pressure, and concentration of the species, and follow the evolution of them using FTIR spectroscopy. I wrote Matlab codes to streamline the analysis of theses data and visualize them. I also wrote codes to analyse the particles light scattering behavior and particle size distribution effect on it.

Research Assistant

Aug 2010 - Dec 2012 (2 years)

I conducted research to study the photochemical reactions of some simple molecules species isolated at low temperatures matrices. For that purpose, I used FTIR and laser techniques to monitor the processed and generated interesting molecular and radical species. I also used computational chemistry (Gaussian) to aid the the analysis of experimental data.

Photodissociation of N-methylformamide isolated in solid parahydrogen

We report FTIR studies of the 193 nm photodecomposition of N-methylformamide (NMF) isolated in solid parahydrogen (pH2) matrices at 1.9 K. By studying the detailed photokinetics we can distinguish between primary and secondary photoproducts. We observe single exponential decay of the NMF precursor upon irradiation and identify three competing primary dissociation channels: HCO+ NHCH3; H+ CONHCH3; and CO+ CH3NH2 with branching ratios of 0.46 (7): 0.032 (8): 0.51 (6), respectively.

Quantum Diffusion-Controlled Chemistry: Reactions of Atomic Hydrogen with NO in solid pH2

Fourier transform infrared spectroscopic studies of the 193 nm photoinduced chemistry of nitric oxide (NO) isolated in solid pH2 over the 1.8 to 4.3 K temperature range. Upon short-term in situ irradiation the NO readily undergoes photolysis to yield HNO, NOH, NH, NH3, H2O, and H atoms. We map the postphotolysis reactions of mobile H atoms with NO and document first-order growth in HNO and NOH reaction products for up to 5 h after photolysis.

Spectral curve fitting of dielectric constants

In this study we use dielectric constants of three different molecular ices in the infrared region to evaluate four different model curves that are generally used for fitting optical constants: (1) the classical damped harmonic oscillator, (2) Voigt line shape, (3) Fourier series, and (4) the Triangular basis. Among these, only the classical damped harmonic oscillator model strictly satisfies the Kramer-Kronig relation.

Infrared characterisation of acetonitrile and propionitrile aerosols under Titan's conditions

Pure, crystalline acetonitrile (CH3CN) and propionitrile (CH3CH2CN) particles were formed in a collisional cooling cell allowing for infrared (IR) signatures to be compiled from 50 to 5000 cm− 1. The cell temperature and pressure conditions were controlled to simulate Titan's lower atmosphere (80–130 K and 1–100 mbar), allowing for the comparison of laboratory data to the spectra obtained from the Cassini–Huygens mission.
