Allosteric Determinants of Guanine Nucleotide Binding Proteins and Methods to Crystallize the Cytosolic Domains of Adenylyl Cyclase
… the absence of Gsa. Unfortunately, this complex crystallized but failed to diffract due to heterogeneity. Intein-mediated protein ligation and expression of a C1-C2 fusion protein in adenylyl cyclase deficient Escherichia coli were explored to circumvent the low affinity of the domains. However, …

Heterogeneity of the Bc1 Complex Subunits and Qo Site Occupants From Rhodobacter Sphaeroides
… anecdotal data regarding how difficult it is to crystallize membrane proteins but these facts are never rigorously evaluated, because virtually no one can report all the reasons why membrane proteins do not crystallize easily. Trials to crystallize bc1 complex from R. sphaeroides, a …

Crystallization process development and spherical agglomerates for pharmaceutical processing applications
… the final product. The processes were able to crystallize the two compounds with both high yield (>90%) and purity (>99%). Population balance modeling was performed and experimental data were fit to the model to obtain kinetic parameters for crystal growth and nucleation for both systems. The …

Order and disorder: a hotel in Alexandria, Virginia
… a hotel has been chosen. The secondary theme to crystallize my beliefs about urban design was possible by choosing a site of inherent complexity in a diverse context.

Studies of blends containing liquid crystalline polymers with PET and related investigations of hydroquinone/biphenol polysulfone systems
… character and to note their ability to thermally crystallize as well as to crystallize by solvent or strain inducement. Along these lines, thermal analysis, polarizing hot-stage microscopy, wide angle x-ray scattering and mechanical testing were utilized in this investigation

Fundamental studies on ionomer glasses
… (fluorite) and anorthite. The anorthite phase crystallized from fluorite nuclei and, in effect, crystallization occurred by a bulk nucleation mechanism. The glass will also undergo significant crystallization to fluorite below the glass transition temperature, with surface nucleation the …

Study of the miscibility, morphology, crystallization, and melting behavior of blends of poly(3-hydroxybutyrate) and poly(vinylidene fluoride)
… crystallization studies indicate that PVDF crystallizes first in all blends containing more than 30% PVDF, and that the blends exhibit single phase behavior in the liquid state. Studies of the melting of isothermally crystallized samples indicate a melting point depression for melt blended …

Gas transport properties of poly(n-alkyl acrylate) blends and modeling of modified atmosphere storage using selective and non-selective membranes
… The side chains of poly(n-alkyl acrylate)s crystallize independently of the main chain for n [is greater than or equal to] 10 which leads to an extraordinary increase in the permeability at the melting temperature of the crystallites. The compatibility of these polymers are examined and …

Annular Flow Synthesis and Assembly of Two-Dimensional Materials
… to find that layered double hydroxides (LDH) may crystallize via oriented attachment, which is accelerated by hydrodynamic flow. These observations are used to formulate a mechanism that explains the non-monotonic variation in particle characteristics using characteristic kinetic timescales. I …

Two competitions
… individual, it is an exercise in the ability to crystallize ideas and communicate them clearly - often exclusively through graphic means. Competitions are also a means of further developing one’s pre-existing ideas, as well as, investigating new ones. Collectively, they provide the opportunity of …

Synthesis, X-ray characterization, structural and magnetic studies of a new class of iso-structural BiMO₃ compounds
… reported in the second part. These compounds all crystallize in the body centered cubic (BCC) structure with a~10.2Å. Single crystal Precession and Weissenberg photographs confirmed the BCC structure. In part three, the results of the magnetic studies on BiCoO₃ and biAl.₉FE.₁ are presented. The …

The Effect of Ionomer Architecture on the Morphology in Gel State Functionalized Sulfonated Syndiotactic Polystyrene
… functionalized copolymer was no longer able to crystallize, whereas, the blocky functionalized copolymer is able to crystallize even at a functionalization level of 10.5% sulfonate groups. When considering the morphology of these systems even at low percentages of sulfonation it is clear that …

The Creation of a Worldview.
… Adolf Hitler’s Weltanschauung did not completely crystallize until after World War I, much of what contributed to his personal and political ideology resulted from his personal experiences in Vienna.</p>

The atomic and magnetic structures of several iron-substituted rare-earth manganese germanides and stannides
… by Mӧssbauer spectroscopy. All germanides crystallize in the disordered YCo<sub>6</sub>Ge<sub>6</sub>-type structure, whereas the stannides crystallize in the HoFe<sub>6</sub>Sn<sub>6</sub>-type and the TbFe<sub>6</sub>Sn<sub>6</sub>-type structure for the non-substituted samples and the …

AN EXAMINATION OF BINDING DIFFERENCES AMONG MISMATCH REPAIR RECOGNITION PROTEINS WITH MISMATCH AND CISPLATIN DAMAGED DNA
… anisotropy binding experiments and to crystallize the proteins in complex with cisplatin damaged DNA for comparison to mismatch DNA binding. All three mismatch repair (MMR) recognition complexes proved capable of binding cisplatin damaged DNA, but only MSH2-MSH6 demonstrated increased …

Insights into structure, dynamics of thioredoxin reassembly and dynein light chain 8 and ionization states of thiamin cofactor by MAS NMR spectroscopy
… assemblies that are insoluble and difficult to crystallize. A number of laboratories including ours are working on developments of MAS technologies that would enable analysis of complex biological systems. In this dissertation, the applications of MAS NMR approaches to two types of problems in …

The Effect of Nitrogen on The Crystallization Behavior of Barium-Silicon-Aluminum-Oxygen-Nitrogen Oxynitride Glasses (Phase Separation, Crystal Growth)
… in nitrogen. The droplet phase was the first to crystallize, followed by the growth of crystals into the matrix by an interface-controlled process. The final microstructure consisted mainly of interlocking clusters of lath-shaped crystals with some residual glass dispersed among the crystals. The …

Applications of DNP and solid-state NMR for protein structure determination
… as amyloidogenic fibrous proteins, that do not crystallize or dissolve well and are therefore not amendable to X-ray or solution NMR techniques. However, due to inherently low sensitivity, NMR experiments may require weeks to obtain spectra with sufficient signal-to-noise ratio. This issue is …
