A surface molecularly imprinted nanowire is designed by chemical polymerization of dopamine in neutral aqueous solution, which shows high binding capacity and acceptable specific recognition behavior towards template proteins.

Conjugated polymer nanoparticles, produced by in situ colloidal Knoevenagel polymerization, show advantageous properties (bright emission, colloidal/chemical stability and mesoscopic size range) that allow the successful in vivo application to real-time sentinel lymph node mapping in a mouse model.

Metal coordination polymer nanoboxes are reported for the first time. Initially spherical miniemulsion droplet templates were transformed to hollow cubic crystalline nanostructures via a miniemulsion periphery polymerization conducted under benign thermal and chemical conditions.

Core/shell nanomaterials composed of only polypyrroles (PPys) were fabricated by microemulsion polymerization using two oxidants with different chemical oxidation potentials, and used as a precursor for the fabrication of PPy and carbon nanocapsules.

Measurement of polymerization degree of condensed phosphates was examined by solid-state NMR. Broad peaks of the NMR of endand middle-PO4 groups of condensed phosphates were observed at about 1 and -20 ppm, respectively. The NMR. peak area ratio (Ro) of middle-PO4 group to end-PO4 group has the following relation with the polymerization degree (n) of polyphosphate: Ro (middle-PO4/end-PO4) = (n-...

Recently, great emphasis has been placed on the fabrication of chemical and topographical functional materials on both the micrometer and nanometer scale, due to novel phenomena that occur at this scale. Most techniques reported to date suffer from the ability to satisfy the different material requirements and makes it difficult to reproduce both topographical patterns with a wide range of well...

A high-throughput multiparameter optimization of chemical oxidative polymerization conditions has been developed for a facile synthesis of furan homopolymers and furan/aniline copolymers using a combinatorial method. The polymerization yield, molecular structure, and properties of the polymers would be optimized against typical polymerization parameters, including oxidant species, medium specie...

The interaction of the external donor (propyltrimethoxysilane - PTMS) with titanium-magnesium catalysts (TMCs) containing dibutylphthalate (DBP) as internal donor, which were prepared in different ways, was studied by chemical analysis and infrared diffuse reflectance spectroscopy (DRIFTS). The chemical composition of the catalysts after their interaction with heptane solutions of PTMS, PTMS/Al...

The aim of this research was to produce a convenient additive for enhancing the properties, especially the fluid loss, of oil well cement slurries. In this regard, a variety of drilling/cementing chemical additives known as fluid loss controllers were prepared through derivatization and chemical modification of lignite. Lignite-based graft copolymers were synthesized using different groups of a...
