High As exposure induced substantial arsenite efflux in As-hyperaccumulator Pteris vittata
Arsenite (AsIII) efflux is an important mechanism for arsenic (As) detoxification in plants. Low AsIII efflux has been observed in As-hyperaccumulator Pteris vittata, which may contribute to its highly efficient As translocation and accumulation; however, the results may be compromised by microbial AsIII oxidation, relatively low As concentration in the medium and short-term As exposure. Here, s...

Preparation and properties of electron injecting molecular hybrid materials with high thermal performance
A series of oxadiazole-containing molecular hybrid materials with different structures (H1–H5) are controllably prepared by a hydrosilylation method based on the octahydridosilsesquioxane (POSS, T8H). All these resultant hybrid materials are soluble in common organic solvents, such as chloroform, toluene, tetrahydrofuran, and 1,2-dichloroethane, and possess good film-forming prop...

Structural engineering of waterborne polyurethane for high performance waterproof coatings
A series of modified waterborne polyurethanes were synthesized using a self-emulsifying method for high performance waterproof coatings, such as fluoride polyurethane (FPU), siloxane modified waterborne polyurethane (SPU) and the polyurethane containing fluorine and siloxane (FSPU). The structures of waterborne polyurethane were designed from scratch, and the contents of fluoride ...

95. High-sensitive detection of dopamine using graphitic carbon nitride by electrochemical method
A simple electrochemical biosensor was developed based on graphitic carbon nitride polymers (g-CN) modified glass carbon electrode (g-CN/GCE). The modified electrode displayed the electrochemical sensitive to dopamine (DA) and showed a good linear and broad response to detect of DA. The inorganic ions had no effect on detecting of DA as well. The decreasing of electrochemical activity was only a...

Anomalous high photovoltages observed in shish kebab-like organic p-n junction nanostructures
We report the observation of anomalous high photovoltages, which
are significantly higher than the energy level offset between the
highest occupied molecular orbital (HOMO) of the electron donor (D)
and the lowest unoccupied molecular orbital (LUMO) of the acceptor
(A), in single trunk shish kebab-like organic p–n junction nanostructures.
Creation of such high photovoltages is likely due to the
s...

Recent progress in nanoscale morphology control for high performance polymer solar cells
The nanoscale morphology of the electronic donor and acceptor materials in photoactive layers significantly
influences both the exciton split and charge carrier delocalization and extraction processes in prevalent bulkheterojunction
(BHJ) based polymer solar cells (PSCs). An optimized morphology, including interpenetrating
networks of donor and acceptor materials, nanoscale phase separation, and a...

A novel high flux poly(trimethylene terephthalate) nanofiber membrane for microfiltration media
A novel high flux poly(trimethylene terephthalate) (PTT) nanofiber membrane for microfiltration media
was prepared and characterized in this study. The PTT nanofibers for the membrane preparation were
fabricated based on a high throughput, cost effective and environmental friendly method developed by
us. The PTT nanofiber membranes were then prepared by a wet-laid process. To enhance the mechanica...

Synthesis of zinc N-morpholinomethylphosphonic acid and its application in high density polyethylene
Zinc N-morpholinomethylphonic acid (MMPA-Zn) with layered structure was synthesized via hydrothermal reaction between zinc acetate and N-morpholinomethylphonic acid. Thermal gravimetric analysis (TGA) showed that MMPA-Zn has good thermal stability and char-forming ability with high onset decomposition temperature of 391 oC and high residual char at 700 °C of 65.3 wt%. The flame retardancy of high...

Preparation of high-magnetization Fe3O4–NH2–Pd (0) catalyst for Heck reaction
A magnetically separable Fe3O4–NH2–Pd (0) catalyst was easily synthesized by immobilizing Pd nanoparticles on the surface of magnetic Fe3O4–NH2 microspheres. It was found that the combination of Fe3O4 and triethylene tetramine (TETA) could give rise to structurally stable catalytic sites. Furthermore, the high-magnetization Fe3O4–NH2–Pd(0) catalyst can be recovered by magnet and r...

Imparting cellulosic paper of high conductivity by surface coating of dispersed graphite.
Cellulosic paper, when imparted with strong conductivity, may have important applications. In the present work, graphite-based coatings were fabricated and directly applied onto the surface of a low-grade paper made of recycled fibers to produce conductive paper. Sodium dodecyl sulfate (SDS)-graphite aqueous dispersion was developed, in order to attain the graphite suspensions with high solid cont...
