Persistent Organic Pollutants in the East Antarctic Atmosphere: Inter-Annual Observations from 2010 to 2015 Using High-Flow-Through Passive Sampling.
Publication Type: Academic Journal
Source(s): Environmental Science & Technology. 12/5/2017, Vol. 51 Issue 23, p13929-13937. 9p.
Abstract: In the first multiyear sampling effort for POPs in the eastern Antarctic atmosphere, 32 PCBs and 38 organochlorine pesticides were targeted in air collected with a high-flow-through passive sampler. Agricultural chemicals were found to dominate atmosph...
Inter- and Intramolecular Bonding in 1,3,5-Triamino-2,4,6-trinitrobenzene: An Experimental and Theoretical Quantum Theory of Atoms in Molecules (QTAIM) Analysis.
Publication Type: Academic Journal
Source(s): Crystal Growth & Design. Oct2017, Vol. 17 Issue 10, p5200-5207. 8p.
Abstract: Chemical bonding in the triclinic phase of 1,3,5-triamino-2,4,6-trinitrobenzene (TATB) has been analyzed based on the experimental electron density derived from X-ray diffraction data obtained at 20 K. The results have been compared with those from sol...
Discerning Inter- and Intramolecular Vibrations of Sulfur Polyaromatic Compounds.
Publication Type: Academic Journal
Source(s): Journal of Physical Chemistry A. Sep2017, Vol. 121 Issue 38, p7205-7218. 14p.
Abstract: Thiophenes are an important class of molecules in fields as diverse as petrochemistry, molecular electronics, and optoelectronics. Thiophenic submolecular motifs are thought to play a role in molecular association and nanoaggregation phenomena in both ...
Mass Spectral Library Quality Assurance by Inter-Library Comparison.
Publication Type: Academic Journal
Source(s): Journal of the American Society for Mass Spectrometry. Apr2017, Vol. 28 Issue 4, p733-738. 6p.
Abstract: A method to discover and correct errors in mass spectral libraries is described. Comparing across a set of highly curated reference libraries compounds that have the same chemical structure quickly identifies entries that are outliers. In cases where t...
Dynamic Characterization of Inter- and Intralamellar Domains of Cobalt-Based Layered Double Hydroxides upon Electrochemical Oxidation.
Publication Type: Academic Journal
Source(s): Chemistry of Materials. Nov2016, Vol. 28 Issue 21, p7793-7806. 14p.
Abstract: This work investigated in situ changes in the structure of the layered double hydroxides (LDH) during electrochemical processes as well as followed the ion motion related to the charge balancing process. Electrogravimetric measurements, using an electr...
Copper-Catalyzed Inter/Intramolecular N-Alkenylation of Benzimidazoles via Tandem Processes Involving Selectively Mild Iodination of sp³ C-H Bond at α-Position of Ester.
Publication Type: Academic Journal
Source(s): Journal of Organic Chemistry. 10/7/2016, Vol. 81 Issue 19, p8806-8815. 10p.
Abstract: Inter/intramolecular approaches to sp² C-N bond formation of N-alkenyl benzimidazoles have been accomplished in the presence of an iodide anion associated with a copper catalyst. Both intermolecular and intramolecular reactions included tandem processe...
Failure of the IDA in FRET Systems at Close Inter-Dye Distances Is Moderated by Frequent Low κ² Values.
Publication Type: Academic Journal
Source(s): Journal of Physical Chemistry B. Sep2016, Vol. 120 Issue 34, p8845-8862. 18p.
Abstract: Förster resonance energy transfer (FRET) is analyzed in terms of distance- and orientation-dependent interactions between the transition dipole moments of the involved donor and acceptor molecules. However, the ideal dipole approximation (IDA) is known...
