Tris(2-(1H-tetrazol-1-yl)ethyl)amine (1) was synthesized as gas-generating agent and characterized by vibrational (IR) and NMR spectroscopy. The energetic properties were determined by bomb calorimetric measurements along with calculations using the EXPLO5 software. Tris(2-(1H-tetrazol1-yl)ethyl)amine (1) was used for further reactions with copper(II) nitrate to form a three-dimensional coordin...

We present an introductory overview of several challenging problems in the statistical characterisation of turbulence. We provide examples from fluid turbulence in three and two dimensions, from the turbulent advection of passive scalars, turbulence in the one-dimensional Burgers equation, and fluid turbulence in the presence of polymer additives.

Inorganic hydrophobically capped NPs such as quantum dots, superparamagnetic iron oxide, or gold nanoparticles can be modified to make them water-soluble by their embedding in an amphiphilic polymer shell. This polymer shell can be prefunctionalized by the integration of organic fluorophores, which allows the observation of the nanoparticles with fluorescence based techniques. The fluorophore c...

Oils, organic solvents, dyes, and heavy metal ions are primary pollutants in water resources. Currently, no sorbent material can effectively remove these types of pollutants simultaneously. Here we report a perfluorous conjugated microporous polymer with superhydrophobicity and a large surface area, which exhibits outstanding adsorption capacities, kinetics, and recyclability for a wide range o...

We report the optoelectronic properties occurring in single-walled carbon nanotubes ~SWNTs!— conjugated polymer, poly~3-octylthiophene! composites. Composite films were drop or spin cast from a solution on indium–tin oxide ~ITO! and quartz substrates and studied using absorption spectroscopy and electrical characterization methods. Diodes ~Al/polymer-nanotube composite/ ITO! with a low nanotube...

We report a simple and convenient method for fabricating ordered porous structure in a polymeric thin film. A temporarily stabilized water-in-oil emulsion, where aqueous droplets were dispersed in the medium of polymer-organic solvent solution, was utilized for the preparation of porous structure. The water-in-oil emulsion was simply prepared by sonicating the mixture of water and polymer-organ...

Organic field-effect transistors (OFETs) are used to directly "touch" the movement and dynamics of polymer chains, and then determine Tg. As a molecular-level probe, the conducting channel of OFETs exhibits several unique advantages: 1) it directly detects the motion and dynamics of polymer chain at Tg; 2) it allows the measurement of size effects in ultrathin polymer films (even down to 6 nm),...

We will study time dependence of interchain contacts in entangled and unentangled polymer melts. We find that ‘‘clusters’’ of contacts in entangled melts persist in time up to at least 0.2 of the longest relaxation time. The clusters of contacts in un-entangled melts disappear and reappear on at least two orders of magnitude shorter time scale. We also examine time-dependent correlation functio...
