Electrostatic assembly between Fe3O4 nanospheres and graphene oxide, subsequent hydrothermal with additional sheets, leads to encapsulated in the shells interconnected by networks. Such 3D Fe3O4/graphene foams exhibit enhanced lithium storage excellent cycling performance rate capability.
Field-effect transistors with highly ordered active layers are fabricated by zone-casting discotic dodecyl-substituted hexa-peri-hexabenzocoronene molecules onto hydrophobic substrates to form semiconducting columnar structures (see Figure). The discs columns that possess long-range order on the scale of square centimeters, and devices show order-of-magnitude improvements in charge-carrier mobilities over previously reported devices.
Recently, two different groups have reported independently that the mobility of field-effect transistors made from regioregular poly(3-hexylthiophene) (P3HT) increases strongly with molecular weight. Two models were presented: one proposing carrier trapping at grain boundaries and second putting emphasis on conformation packing polymer chains in thin layers for weights. Here, we present results detailed investigations powders films deuterated P3HT fractions For powder samples, gel permeation...
We report on the visualization of protein-corona and -composition, formed around nanoparticle systems in contact with biological environments.
The synthesis of in situ polymer‐functionalized anatase TiO 2 particles using an anchoring block copolymer with hydroxamate as coordinating species is reported, which yields nanoparticles (≈11 nm) multigram scale. Thermal annealing converts the polymer brushes into a uniform and homogeneous carbon coating proven by high resolution transmission electron microscopy Raman spectroscopy. strong impact particle size well on electrochemical performance demonstrated. Downsizing leads to higher...
Composites that show visible light transmittance, UV absorption, and moderately high refractive index, based on poly(methyl methacrylate) (PMMA) zinc oxide (zincite, ZnO) nanoparticles, were prepared in two steps. First, surface-modified ZnO nanoparticles with 22 nm average diameter nucleated by controlled precipitation via acid-catalyzed esterification of acetate dihydrate pentan-1-ol. The surface growing crystalline particles was modified tert-butylphosphonic acid (tBuPO3H2) situ monolayer...
Precursor-controlled thermolysis has been developed to specifically prepare structured carbonaceous materials (see figure) by using simple, but structurally defined, organic–cobalt complexes as starting compounds. The carbon–metal nanocomposites show excellent lithium storage properties an anode material in lithium-ion batteries after controllable oxidation. They may also be useful catalysts for fuel cells and other heterocatalytic reactions sensors detecting chemicals biomaterials....
PVDF thin films prepared under standard processing conditions have a cloudy appearance and are notoriously rough, which prevent microelectronic photonic applications. On the other hand, high optical quality, smooth can be either at low relative humidity or substrate temperature. Here we systematically investigate morphology of by varying conditions. Films characterized SEM AFM measurements clarity, haze absorption. We show that is due to vapor-induced phase separation (VIPS) as...
A facile one-step approach is developed to prepare novel carbon/tin composites with hollow tin nanoparticles coated by amorphous carbon (see picture) through the solid-state pyrolysis of allyltriphenyltin. The composite exhibited highly reversible Li storage behavior and improved rate performance as an anode material in a secondary battery.

Silicatein-α is responsible for the biomineralization of silicates in sponges. We used silicatein-α to guide self-assembly calcite "spicules" similar spicules calcareous sponge Sycon sp. The self-assembled spicules, 10 300 micrometers (μm) length and 5 μm diameter, are composed aligned nanocrystals. initially amorphous but transform into within months, exhibiting unusual growth along [100]. They scatter x-rays like twinned crystals. Whereas natural evidence brittle failure, synthetic show an...
