Size matters for polyP to clot ---------------------------------------------------------------------------------------------------------------Usha R. Pendurthi THE UNIVERSITY OF TEXAS HEALTH SCIENCE CENTER AT TYLER All living organisms contain polyphosphate—a linear polymer of inorganic phosphate. Depending on where they are derived, the polymers exist in different lengths. In this issue of Blo...

A facile synthesis of polymer-inorganic hybrid hollow mesoporous nanospheres was developed based on the entrapment of a dissolved polymer core template in the framework during the assembly process of the hybrid hollow nanospheres for efficient and size-selective enrichment of target peptides/proteins from complex biosamples.

Crystallization of poly(vinyl alcohol) in the presence of an inorganic filler surface (sodium montmorillonite, MMT) was observed and compared to the crystallization of the neat polymer. For this purpose, several atomic force microscopy modes, providing spatial resolution between amorphous and crystalline polymer, are employed to observe filled and unfilled PVA films. The various AFM modes utili...

Transparent Nonlinear Optical (NLO) inorganic/organic (polyimide/silica) hybrid composites with covalent links between the inorganic and the organic networks were prepared by the sol-gel method. The silica content in the hybrid films was varied from 0 to 22.5/wt%. The prepared PI hybrids were characterized by IR, UV-Vis, Thermogravimetric analysis (TGA), X-ray diffraction (XRD), Scanning Electr...

INVESTIGATION OF THE FRACTURE PHENOMENA DURING THE MILLING PROCESS OF INORGANIC PARTICULATES AND BRITTLE FRACTURE OF POLYMER COMPOSITES USING FRACTAL THEORY

Cadmium telluride (CdTe) tetrapods were synthesized via multiple injections of the Te precursor by utilizing bifunctional ligands. Subsequently, tetrapod-shaped semiconducting inorganic-organic nanocomposites (i.e., P3HT-CdTe tetrapod nanocomposites) were produced by directly grafting conjugated polymer ethynyl-terminated poly(3-hexylthiophene) (i.e., P3HT-≡) onto azide-functionalized CdTe tetr...

Inorganic dispersion is of great importance for actual implementation of advanced properties of organic-inorganic composites. Currently, electron microscopy is the most conventional approach for observing dispersion of inorganic fillers from ultrathin sections of organic-inorganic composites at the nanoscale by professional technicians. However, direct visualization of macrodispersion of inorga...

This paper focuses on the attachment of densely grafted polymer layers (polymer brushes) to various inorganic and polymeric substrates by the "grafting to" method. A brief overview of synthesis of polymer brushes by the method is first provided, with emphasis on chemical approaches to polymer attachment. The second part of the paper covers the synthesis of polymer layers via a recently develope...

The speciation distribution, physico-chemical properties of coagulants, and principles for their further species transformation under various water and wastewater treatment conditions are of paramount importance in coagulation processes. In this paper, the effect of various factors on the speciation transformation of typical inorganic polymer flocculants (IPFs)–polyaluminum chloride (PACl) was ...
