Cain, Caitlin N.;Trinklein, Timothy J.;Ochoa, Grant S.;Synovec, Robert E. research published 《 Tile-Based Pairwise Analysis of GC x GC-TOFMS Data to Facilitate Analyte Discovery and Mass Spectrum Purification》, the research content is summarized as follows. A new tile-based pairwise anal. workflow, termed 1v1 anal., is presented to discover and identify analytes that differentiate two chromatograms collected using comprehensive two-dimensional (2D) gas chromatog. coupled with time-of-flight mass spectrometry (GC x GC-TOFMS). Tile-based 1v1 anal. easily discovered all 18 non-native analytes spiked in diesel fuel within the top 30 hits, outperforming standard pairwise chromatog. analyses. However, eight spiked analytes could not be identified with multivariate curve resolution-alternating least-squares (MCR-ALS) nor parallel factor anal. (PARAFAC) due to background contamination. Analyte identification was achieved with class comparison enabled-mass spectrum purification (CCE-MSP), which obtains a pure analyte spectrum by normalizing the spectra to an interferent mass channel (m/z) identified from 1v1 anal. and subtracting the two spectra. This report also details the development of CCE-MSP assisted MCR-ALS, which removes the identified interferent m/z from the data prior to decomposition In total, 17 out of 18 spiked analytes had a match value (MV) > 800 with both versions of CCE-MSP. For example, MCR-ALS and PARAFAC were unable to decompose the pure spectrum of Me decanoate (MVs < 200) due to its low 2D chromatog. resolution (~0.34) and high interferent-to-analyte signal ratio (~30:1). By leveraging information gained from 1v1 anal., CCE-MSP and CCE-MSP assisted MCR-ALS obtained a pure spectrum with an average MV of 908 and 964, resp. Furthermore, tile-based 1v1 anal. was applied to track moisture damage in cacao beans, where 86 analytes with at least a 2-fold concentration change were discovered between the unmolded and molded samples. This 1v1 anal. workflow is beneficial for studies where multiple replicates are either unavailable or undesirable to save anal. time.

Biodiesel produced from non-edible oils has received intensive attention in recent years. Herein, a series of novel amphipathic ionic liquids (ILs) based on the 4-dimethylaminopyridine (DMAP) were prepared for the transesterification of soapberry oil and methanol. The structures of the prepared ILs were systematically characterized by both Fourier transform IR spectroscopy (FT-IR) and NMR (NMR, ¹H NMR and ¹³C NMR). In addition, the effects of side-chain length of cation and the number of active site (H⁺) of ILs on the biodiesel yield were investigated, and the results suggested that 1-dodecyl-(4-dimethylammonium)-pyridinium bisulfate ([C12-DMAPH][HSO₄]₂) exhibited the highest catalytic efficiency. Meanwhile, [C12-DMAPH][HSO₄]₂ was proven to be amphipathic, and the corresponding catalytic mechanism was proposed. Under the catalysis of [C12-DMAPH][HSO₄]₂, the optimum operating conditions of transesterification of soapberry oil and methanol were explored via the combination of single factor experiment and response surface methodol., obtaining the high biodiesel yield of (98.02 ± 0.36)% under the optimum operating conditions. Importantly, [C12-DMAPH][HSO₄]₂ exhibited high stability in the transesterification of soapberry oil and methanol in five consecutive runs. Furthermore, the catalytic activities of [C12-DMAPH][HSO₄]₂ towards other transesterification of non-edible oils and lower alcs. were also investigated, which indicated a general applicability of the prepared IL.

We show that a surface-grafted polymer brush, 1-n-butyl-3-vinyl imidazolium bromide-based poly(ionic liquids), is able to reduce the interfacial friction by up to 66% and 42% in dodecane and water, resp. AFM-based force spectroscopy reveals that the polymer brush adopts distinctively different interfacial conformations: swollen in water but collapsed in dodecane. Minimal surface adhesion was observed with both polymer conformations, which can be attributed to steric repulsion as the result of a swollen conformation in water or surface solvation when the hydrophobic fraction of the polymer was exposed to the dodecane. The work brings addnl. insight on the polymer lubrication mechanism, which expands the possible design of the polymer architecture for interfacial lubrication and modification.

Bur, Scott K.;Pomerantz, William C. K.;Bade, Morgan L.;Gee, Clifford T. research published 《 Fragment-Based Ligand Discovery Using Protein-Observed ¹⁹F NMR: A Second Semester Organic Chemistry CURE Project》, the research content is summarized as follows. Curriculum-based undergraduate research experiences (CUREs) have been shown to increase student retention in STEM fields and are starting to become more widely adopted in chem. curricula. Here we describe a 10-wk CURE that is suitable for a second-semester organic chem. laboratory course. Students synthesize small mols. and use protein-observed ¹⁹F (PrOF) NMR to assess the small mol.’s binding affinity to a target protein. The research project introduced students to multistep organic synthesis, structure-activity relationship studies, quant. biophys. measurements (measuring Kd from PrOF NMR experiments), and scientific literacy. Docking experiments could be added to help students understand how changes in a ligand structure may affect binding to a protein. Assessment using the CURE survey indicates self-perceived skill gains from the course that exceed gains measured in a traditional and an inquiry-based laboratory experience. Given the speed of the binding experiment and the alignment of the synthetic methods with a second-semester organic chem. laboratory course, a PrOF NMR fragment-based ligand discovery lab can be readily implemented in the undergraduate chem. curriculum.
