Article Snippet: At contaminated field sites where active remediation measures are not feasible, monitored natural attenuation is sometimes the only alternative for surface water or groundwater decontamination.. However, due to slow degradation rates of some contaminants under natural conditions, attenuation processes and their performance assessment can take several years to decades to complete.. Here, we apply quantum chemical calculations to predict contaminant persistence in the aqueous phase. Article Title: Near-UV circular dichroism and UV resonance Raman spectra of individual tryptophan residues in human hemoglobin and their changes upon the quaternary structure transition. Article Snippet: The aromatic residues such as tryptophan (Trp) and tyrosine (Tyr) in human adult hemoglobin (Hb A) are known to contribute to nearUV circular dichroism (CD) and UV resonance Raman (RR) spectral changes upon the R → T quaternary structure transition.. In Hb A, there are three Trp residues per αβ dimer: at α14, β15, and β37.. To evaluate their individual contributions to the R → T spectral changes, we produced three mutant hemoglobins in E. coli; rHb (α14Trp→Leu), rHb (β15Trp→Leu), and rHb (β37Trp→His). Article Title: Quantum chemical prediction of redox reactivity and degradation pathways for aqueous phase contaminants: an example with HMPA. Article Snippet: Models used to predict the fate of aqueous phase contaminants are often limited by their inability to address the widely varying redox conditions in natural and engineered systems.. Here, we present a novel approach based on quantum chemical calculations that identifies the thermodynamic conditions necessary for redox-promoted degradation and predicts potential degradation pathways.. Hexamethylphosphoramide (HMPA), a widely used solvent and potential groundwater contaminant, is used as a test case. Article Title: Photopolymerization of self-assembled monolayers of diacetylenic alkylphosphonic acids on group-III nitride substrates. Article Snippet: This paper describes the fabrication and characterization of photopolymerizable alkylphosphonate self-assembled monolayers (SAMs) on group-III nitride substrates includingGaNandAlxGa1-xN(AlGaN; x=0.2 and 0.25).. Contact angle goniometry, visible absorption spectroscopy, and atomic force microscopy were used to assess the formation, desorption, and photopolymerization of SAMs of diacetylenic alkylphosphonic acids (CH3(CH2)n-CtC-CtC(CH2)mPO(OH)2; (m, n) = (3, 11), (6, 8), and (9, 5)).. As with GaN substrates (Ito, T.; Forman, S. M.; Cao, C.; Li, F.; Eddy, C. R., Jr.; Mastro, M. A.; Holm, R. T.; Henry, R. L.; Hohn, K.; Edgar, J. H. Langmuir 2008, 24, 6630-6635), alkylphosphonic acids formed SAMs on UV/O3-treated AlGaN substrates from their toluene solutions in contrast to other primary substituted hydrocarbons with a terminal -COOH, -NH2, -OH, or -SH group. |
