Application of Proteomics and Lipid Studies in Environmental Biotechnology

The overview of changes in protein levels or states in response to a growth condition, stress, mutation or metabolic engineering is invaluable in understanding the physiology of a microbial system. The lipid profile of the cell is similarly a valuable diagnostic of the cellular response and health, especially in context of survival in a fluctuating environment. To obtain comprehensive cellular models, post-transcriptional cell wide surveys at the levels of proteins and lipids are required. Both these fields have been greatly bolstered by the development of high throughput methods using mass spectrometry. Multiple strategies now exist for the identification of proteins, and numerous workflows to quantify protein abundance have also been developed. Cellular profiling such as these allows us to assess the potential of a microbial system for environmental applications such as bioremediation and bio-energy.

Do the Defects Make it Work? Defect Engineering in π - Conjugated Polymer Films and Their Solar Cells

The summaries of this report are: (1) charged defects produce 10{sup 15}-10{sup 17} cm{sup -3} free carriers; (2) treatment with nucleophiles decreases p{sub f} and {sigma} while treatment with electrophiles does not change p{sub f} but increases {sigma}; (3) both treatments increase {mu}{sub p}, L{sub ex} and stability against photo-degradation; (4) charged defects can improve OPV by increasing conductivity and creating interfacial electric fields but they hurt {mu}{sub p}, L{sub ex} and chemical stability; and (5) a better way--synthesize materials without covalent defects and dope with purposely added, bound dopants.

Direct Comparison of Inverted and Non-inverted Growths of GaInP Solar Cells

The motivation for this presentation is that growing inverted cells may enable technological advances in solar cell fabrication, leading to higher efficiencies. Differences in dopant diffusion during inverted vs. upright growths may lead to differences in atomic depth profiles; changes in carrier concentrations; higher contact resistance and lower overall performance. This presentation summarizes that excellent performance is achievable in both upright and inverted configurations with proper consideration; subtle differences in depth profile QE and JV between upright and inverted growths due to dopant diffusion; and GaInAsN contact layer is resilient to length annealing and more work is necessary to determine why.
