Neutron diffraction with H/D isotopic substitution is used to investigate the structure of low density amorphous ice produced from (1) high density amorphous ice by isobaric warming and (2) very high density amorphous ice by isothermal decompression. Differences are found in the scattering patterns of the two low dens…

We use neutron spectroscopy to determine the nature of the magnetic excitations in superconducting ${\text{BaFe}}_{1.9}{\text{Ni}}_{0.1}{\text{As}}_{2}({T}_{c}=20\text{ }\text{K})$. Above ${T}_{c}$ the excitations are gapless and centered at the commensurate antiferromagnetic wave vector of the parent compound, while…

Abstract A B‐ and N‐doped microporous carbon has been synthesized via a substitution reaction. The obtained carbon exhibited much higher surface area than the previously reported B‐ and N‐doped carbon. The hydrogen storage measurements indicated that the B‐ and N‐doped microporous carbon had a 53% higher storage capac…

We report a simple and low-cost fabrication of antireflection subwavelength grating (SWG) structures on GaAs using the lenslike shape transfer by a holographic lithography and a reflowed photoresist mask. The use of an additional thermal reflow process enhances the close packing of two-dimensional SWGs with a conical…

Au nanoparticle-decorated polypyrrole nanotubes (defined as PPy/Au nanocomposites) are prepared by an in situ reduction process. Polypyrrole (PPy) nanotubes are prepared by a self-degraded template method, and Au nanoparticles are deposited in situ by the reduction of HAuCl(4) . The size and uniformity of the Au nanop…

Abstract Matrix evolutions : We have biochemically characterized the nacre matrix of the cephalopod Nautilus macromphalus , in part by a proteomic approach applied to the acetic acid‐soluble and ‐insoluble shell matrices, as well as to spots obtained after 2D gel electrophoresis. Strikingly, most of the obtained parti…

A facile method to make optoelectronic devices formed from organic thin-film transistors that are functionalized by photochromic spiropyran dyes in a nondestructive manner has been developed. When PDMS stamps are employed, alkane-containing spiropyran molecules can be coated simply onto the surface of organic thin fil…

The assembly line: Hexabenzocoronene amphiphiles appended with pyridyl-terminated triethylene glycol side chains, in combination with trans-[Pt(PhCN)(2)Cl(2)], lead to the formation of graphitic nanotubes. The structural features and dimensions of the nanotubes depend on the assembly conditions. A platinum(II)-bridged…
