Poly(2-oxazoline)s (POx) are currently discussed as an upcoming polymer platform for biomaterials design and especially for polymer therapeutics. POx meet specific requirements needed for the development of next-generation polymer therapeutics such as biocompatibility, high modulation of solubility, variation of size, architecture as well as chemical functionality. Although in the early 1990s f...

The asymmetric unit of the title compound, [Rb(C(7)H(3)N(2)O(7))](n), comprises an Rb(+) cation and a 3,5-dinitro-salicylate ligand. The Rb(+) cation is 10-coordinated by O atoms from eight 3,5-dinitro-salicylate anions and is linked by three μ(2)-O atoms, forming a zigzag chain along the b-axis direction, which is further linked by the phenyl groups, giving the three-dimensional framework. The...

In the title polymeric coordination compound, [Sn(CH(3))(3)(C(10)H(11)O(2))](n), the Sn atom has a distorted trigonal-bipyramidal coordination geometry, with two O atoms of two symmetry-related carboxyl-ate ligands in axial positions and three methyl groups in equatorial positions. In the crystal structure, carboxyl-ate bridges link the metal atoms, forming zigzag chains parallel to the b axis.

In the crystal of the title coordination polymer, [Na(C(8)H(5)N(2)O(6))](n), the Na(I) ion is linked to five nearby anions. Their bonding modes are three monodentate carboxyl-ate O atoms, one O,O'-bidentate carboxyl-ate group and one O,O'-bidentate nitro group. This results in an irregular NaO(7) coordination geometry for the metal ion. This connectivity leads to a layered network propagating i...

Chakraborty, Ankur. M.S., Purdue University, May, 2010. Providing Availability on the Poly^2 Framework. Major Professor: Eugene Spafford, Melissa Dark. Availability is not often a primary concern for frameworks meant to provide security. Poly^2 is one such framework. It provides us with a hardened foundation based on secure design principles to run mission-critical services. While, the primary ...

For the Kirillov–Poisson structure on the vector space g∗, where g is a finite-dimensional Lie algebra, it is known at least two canonical deformations quantization of this structure: they are the M.Kontsevich universal formula [K], and the formula, arising from the classical Campbell–Baker–Hausdorff formula [Ka]. It was proved in [Ka] that the last formula is exactly the part of Kontsevich’s f...

The title compound {systematic name: poly[[μ(7)-(2R)-2-amino-3-sulfonato-propano-ato]disodium]}, [Na(2)(C(3)H(5)NO(5)S)](n), was obtained through solvent-thermal reaction of l-cysteic acid and aqueous sodium hydroxide. The monomer consists of two Na(+) cations that are coordinated to the deprotonated amino acid. The latter acts as donor utilizing all available coordination sites, viz. the amino...

In the structure of the title coordination polymer, [K(C(8)H(5)N(2)O(6))](n), each ligand bridges six K(+) cations. The carboxyl-ate group coordinates both bidentately to one K(+) ion and monodentately to two K(+) ions, while one nitro group coordinates bidentately to a fourth K(+) ion. The last two K(+) ions are coordinated by the remaining nitro group, one in a bidentate fashion, the other mo...

A rapid photo-curing system based on poly(2-ethyl-2-oxazoline-co-2-allylamidopropyl-2-oxazoline) and its in vivo compatibility are presented. The base polymer was synthesized from the copolymerization of 2-ethyl-2-oxazoline (EtOx) methyl ester containing 2-methoxycarboxypropyl-2-oxazoline (C3MestOx) followed by amidation with allylamine to yield a highly water-soluble macromer. We showed that s...

The effect of repeated stimulation on both the interferon and antibody systems and on reticuloendothelial activity was studied by injection of endotoxin 2 days before injection of (poly rI):(poly rC). A single injection of endotoxin or (poly rI):(poly rC) increased or decreased the response in each system depending on the time of administration. If the injection of (poly rI):(poly rC) was prece...
