The challenges faced with current fluorescence imaging agents have motivated us to study two nanostructures based on a hydrophobic dye, 6H-pyrrolo[3,2-b:4,5-b’]bis [1,4]benzothiazine (TRPZ). TRPZ is a heteroacene with a rigid, pi-conjugated structure, multiple reactive sites, and unique spectroscopic properties. Here we coupled TRPZ to a tert-butyl carbamate (BOC) protected 2,2-bis(hydroxymethyl)propanoic acid (bisMPA) dendron via azide-alkyne Huisgen cycloaddition. Deprotection of the protected amine groups on the dendron afforded a cationic terminated amphiphile, TRPZ-bisMPA. TRPZ-bisMPA was nanoprecipitated into water to obtain nanoparticles (NPs) with a hydrodynamic radius that was comparison, TRPZ-PG was encapsulated in pluronic-F127 (Mw = 12 kD), a polymer surfactant …

Further Astrochemical Insights From Bond Strengths Of Small Molecules Containing Atoms From The First Three Rows Of The Periodic Table, Edmund S. Doerksen, Ryan C. Fortenberry Aug 2021

Further Astrochemical Insights From Bond Strengths Of Small Molecules Containing Atoms From The First Three Rows Of The Periodic Table, Edmund S. Doerksen, Ryan C. Fortenberry

Faculty and Student Publications

The atoms contributing to the strongest “single bonds” on the periodic table do not continue to produce the strongest “double bonds” or “triple bonds.” In fact, the opposite appears to be the case. This quantum chemical examination of nominal X = Y and X ≡ Y bonds in model molecules of atoms from the first three rows of the periodic table shows that the strongest “double bond” is in formaldehyde once the astrophysically-depleted Be and B atoms are removed from consideration. The strongest “triple bond” is a close match between acetylene and N2. However, these results indicate that astrophysical regions …

Temporal And Spatial Variations In Three-Dimensional Seismic Oceanography, Zheguang Zou, Parsa Bakhtiari Rad, Leonardo Macelloni, Likun Zhang Aug 2021

Temporal And Spatial Variations In Three-Dimensional Seismic Oceanography, Zheguang Zou, Parsa Bakhtiari Rad, Leonardo Macelloni, Likun Zhang

Faculty and Student Publications

Seismic oceanography is a new cross-discipline between geophysics and oceanography that uses seismic reflection data to image and study the oceanic water column. Previous work on seismic oceanography was largely limited to two-dimensional (2D) seismic data and methods. Here we explore and quantify temporal and spatial variations in three-dimensional (3D) seismic oceanography to address whether 3D seismic imaging is meaningful in all directions and how one can take advantage of the variations. From a 3D multichannel seismic survey acquired for oil and gas exploration in the Gulf of Mexico over a 6-month period, a 3D oceanic seismic volume was derived. …

Shortwave infrared (SWIR) emission has great potential for deep-tissuein vivobiological imaging with high resolution. In this article, the synthesis and characterization of two new xanthene-based RosIndolizine dyes codedPhRosIndz andtolRosIndz is presented. The dyes are characterizedviafemtosecond transient absorption spectroscopy as well as steady-state absorption and emission spectroscopies. The emission of these dyes is shown in the SWIR region with peak emission at 1097 nm.TolRosIndz was encapsulated with an amphiphilic linear dendritic block co-polymer (LDBC) coded 10-PhPCL-G3 with high uptake yield. Further, cellular toxicity was examinedin vitrousing HEK (human embryonic kidney) cells where a >90% cell viability was observed at practical concentrations …

Faculty and Student Publications

The E-hook of β-tubulin plays instrumental roles in cytoskeletal regulation and function. The last six C-terminal residues of the βII isotype, a peptide of amino acid sequence EGEDEA, extend from the microtubule surface and have eluded characterization with classic X-ray crystallographic techniques. The band position of the characteristic amide I vibration of small peptide fragments is heavily dependent on the length of the peptide chain, the extent of intramolecular hydrogen bonding, and the overall polarity of the fragment. The dependence of the E residue’s amide I ν(C=O) and the αCOO− terminal ν(C=O) bands on the neighboring side chain, the length …

Migration, Marginalization, And Institutional Injustice In The Rural South, Jin Young Choi Aug 2021

Migration, Marginalization, And Institutional Injustice In The Rural South, Jin Young Choi

Journal of Rural Social Sciences

At the new beginning of the next 50 years of the Southern Rural Sociological Association (SRSA), the SRSA Presidential Address calls for attention to the issues that rural immigrants have faced – the everyday experiences of international migrants, their marginalization, and institutional injustice in rural America, particularly in the rural South. These issues have often been ignored or downplayed in the larger dialogue on rural issues and in the public debates about immigration policy, even though these social problems have been a perennial issue. Rural social scientists are challenged to be organic intellectuals who do not hide in the ivory …
