Postdoctoral research Scientist - Department of Chemistry and Biochemistry, University of Colorado, Boulder - Deadline ASAP

Postdoctoral opportunities exists to investigate the unique micro-environments that aqueous surface, interfaces and micro-droplets provide, and how they affect organic photochemical reactions. The proposed research includes three related approach.:
(1) fundamental laboratory experiments to probe multiphase, environmentally relevant systems using surface sensitive technique,
(2) environmental chamber studies where conditions approximating the atmosphere can be created, to assess the importance of interface chemical reactions in comparison to the better-studied bulk reactions in the gas and aqueous phases,
(3) reactions confined in micro-droplets and vesicles will be investigated and compared with their bulk and surface counterparts. 

Implications of this research are to planetary chemical processes, including the contemporary and prebiotic Earth. (1) The Earth's ocean-atmosphere system, a Sunlight driven photochemical reactor, is a large and complex system, but has been altered over its existence through both natural and anthropogenic even.. In this global reactor, chemistry occurs in all phase, although gas phase chemistry has received the most attention. It has long been established, however, that heterogeneous and multiphase reactions can be extremely important fora fundamental understanding of environmental chemical reactions, which affect chemical processing, air quality, and ultimately visibility, human health, and the planet's temperature. (2) Starlight provides energy capable of driving planetary processes, which increase a system's chemical complexity. Starlight initiated reactions generate high-energy molecules that are precursors to metabolism as it has evolved in life on Earth. Experiments are designed to investigate the photochemical synthesis and reactivity of such model organic systems under conditions representative of exoplanet Earth analogues, as well as the effect of water on reactivity. Based on this photochemistry, potential spectroscopic probes will be designed for the identification of high energy species and consequently of potentially habitable environments.

Postdoctoral fellow in Atmospheric chemistry at the University of Gothenburg Deadline: 31st of May 2017

Research group : Atmospheric science, Professor Mattias Hallquist (hallq@chem.gu.se), University of Gothenburg

Specific subject description : The aim of this project is to quantify, understand and provide tools to describe atmospheric oxidation of organic compounds. This oxidation is important to understand formation of secondary organic aerosol (SOA) but also the generally production of oxygenated compounds that can effect air quality both in outdoor and indoor environments. Aerosol particles are crucial components in any evaluation process regarding air quality and climate change. SOA represents a significant fraction of the tropospheric aerosol. Still, the current level of understanding of SOA processes is remarkably low compared to other processes in aerosol science, i.e. modelled SOA based on experimental findings and existing theory does not capture the variability of observed SOA loadings and often predicts far less SOA than observed. It has been indicated that biogenic SOA can be largely affected by anthropogenic pollutants, i.e. NO2, SO2 or organic compounds e.g. aromatics and aldehydes. The effect of anthropogenic pollutants may explain part of the discrepancy between models and field observations. Specifically, this project applies high resolution mass spectroscopy techniques for detailed analysis of gas and particle phase to elucidate chemical mechanisms of importance for atmospheric SOA. A specific aim is how to link SOA mechanisms to model developments for descriptions in air quality and climate models.

The experiments will primarily be conducted using our high-resolution time-of-flight chemical-ionization mass spectrometer in combination with inlets separating particle and gas phase for characterization of organic compositions. (FIGAERO-CIMS)

Job assignments : Research in atmospheric chemistry using high resolution mass spectrometry with chemical ionization. The experimental studies can be carried out both in our laboratory but also in the field to study the emissions and secondary transformation of organic compounds in both indoor and outdoor environments. In addition to work in Sweden one is expected to participate in our international collaboration projects, currently with emphasis on India, China, Germany and the UK. The work involves a great deal of analysis and evaluation of measurement data for the understanding and quantification of atmospheric oxidation of organic substances.

Eligibility : The qualifications for academic positions are given in Chapter 4, Section 3 - 4 of the Higher Education Ordinance.

To qualify as a postdoctoral fellow, the applicant must have completed a doctoral degree corresponding to a Swedish doctoral degree. 
Preference will be given to candidates who have been awarded the degree no more than three years before the application deadline Applicants with a degree obtained earlier than the stipulated three years may be preferred if special reasons exists. Special reasons in this context include, but are not limited to, leave due to illness and parental leave.

A requirement is experience in mass spectroscopy with atmospheric application demonstrated by international publications in peer-reviewed journals and experimental work.
Preferences will be given to candidates that have experience in working with a high-resolution time-of-flight chemical-ionization mass spectrometer (HRToF-CIMS), where also previous experience on air quality studies in Beijing or Hong Kong are beneficial.

Assessment : Regulations for the evaluation of qualifications for academic positions are given in Chapter 4, Section 3 - 4 of the Higher Education Ordinance.

Experience in working with a high-resolution time-of-flight chemical-ionization mass spectrometer (HRToF-CIMS) with applications on atmospheric chemistry. Previous experience on air quality studies in Beijing or Hong Kong.

The research group : Our atmospheric science constellation is unique in Sweden in that it takes a molecular approach to transport and reaction processes in the atmosphere. A unifying focus is the study of aerosols, with activities ranging from fundamental studies of chemical reactions on the molecular level, to applied work including field studies of atmospheric processes, their importance to current climate and air quality research. The research contributes to developments in the fields of colloidal chemistry, nanotechnology, medicine as well as development of traffic related chemistry and sustainable development in developing countries.
