Abstract Phosphor‐based polymer composites were prepared using a melt mixing and extrusion method. Morphology, luminescent properties, and Hamburg wheel test (HWT) of synthesized hybrid material were studied using various polymer matrices. The intensities of the luminescence of the strontium aluminates phosphors (SrAl…
Polyhydroxyalkanoates (PHAs) as an attractive biopolymer with a wide range of applications have been extensively studied. Many new strategies have been employed to effectively and economically produce PHAs. This mini-review mainly focuses on the research and development of new PHAs-producing strains, utilization of re…
We propose a modified Josephson corner-junction experiment which can test whether the order parameter in the iron pnictides changes sign between the electron and hole pockets of the Fermi surface.
We examine the effects of void morphology and critical current density (jc) on the electromigration failure distributions of Cu/low-kdual-damascene vias. Cu dual-damascene vias exhibit multiple modes of electromigration-induced voiding, and reliability is strongly dependent on the morphology of voids. We have develope…
Zr-doped ceria nanotubes (Zr x Ce 1− x O 2 ) were obtained in a high yield from a hydrothermal reaction in an aqueous solution of NaOH with Ce(NO 3 ) 3 ·6H 2 O and ZrO 2 powder in a small proportion. The morphology and crystalline structure were characterized with X-ray diffraction, a scanning electron microscope, and…
A Comment on the Letter by D. Pacilé et al., Phys. Rev. Lett. 101, 066806 (2008)10.1103/PhysRevLett.101.066806. The authors of the Letter offer a Reply.
This paper describes the crystallization of l -glutamic acid polymorphs in both quiescent and forced solution flow membrane crystallizers. The β polymorph was selectively obtained in static conditions, while the α form was preferentially grown in dynamic configuration, depending on the rate of solvent removal. Accordi…
Magnetic susceptibility measurements and X-ray data confirm that tert -butyl-substituted manganocenes [(Me 3 C) n C 5 H 5− n ] 2 Mn ( n = 1, 2) follow the trend previously observed with the methylated manganocenes; that is, electron-donating groups attached to the Cp ring stabilize the low-spin (LS) electronic ground…
Interparticle forces that can be driven by applied (optical) fields could lead to the formation of new particle arrangements when assembled in arrays. Furthermore, the potentially large interactions and large local fields associated with plasmon excitations in anisotropic nanoparticles can lead to enhanced nonlinear r…
Cupriavidus necator was engineered aiming to synthesize poly[(R)-3-hydroxybutyrate-co-3-hydroxypropionate] copolyester, P(3HB-co-3HP), from structurally unrelated carbon sources without addition of any precursor compounds. We modified a metabolic pathway in C. necator for generation of 3-hydroxypropionyl-CoA (3HP-CoA)…
dc and ac transport properties as well as electric modulus spectra have been investigated for the samples ${\text{LaMn}}_{1\ensuremath{-}x}{\text{Fe}}_{x}{\text{O}}_{3}$ with compositions $0\ensuremath{\le}x\ensuremath{\le}1.0$. The bulk dc resistivity shows a temperature variation consistent with the variable range h…
We performed quasielastic neutron scattering experiments and atomistic molecular dynamics simulations on a poly(ethylene oxide) (PEO) homopolymer system above the melting point. The excellent agreement found between both sets of data, together with a successful comparison with literature diffraction results, validates…
A very sensitive experimental setup for accurate wavelength-dependent hyper-Rayleigh scattering (HRS) measurements of the molecular first hyperpolarizability beta in the broad fundamental wavelength range of 600 to 1800 nm is presented. The setup makes use of a stable continuously tunable picosecond optical parametric…
The regulation of medium-chain-length polyhydroxyalkanoates (mcl-PHA) metabolism in Pseudomonas putida GPo1 was studied by analysis of enzymes bound to PHA granules and enzymes involved in fatty acid oxidation. N-terminal sequencing of granule-bound enzymes revealed the presence of PHA polymerase (PhaC) and PHA depoly…
Individual shells of the diatom Coscinodiscus were self-assembled into a rectangular array on a glass surface that possessed a polyelectrolyte multilayer patterned through inkjet printing. This patterned thin film possessed hierarchical order with nanostructure provided by the diatom biosilica. The process used two po…
Unprecedented electro-optic (EO) activity and excellent alignment stability at 85 °C are demonstrated through rational design of a new series of dendronized polyenic chromophores capable of supramolecular self-assembly directed by fine-tuned arene–perfluoroarene interactions. Analysis of the EO properties showed excep…
By exploiting photoinduced reorientation in azo-polymer thin films, we demonstrate all-optical polarization-encoded information storage with a scanning near-field optical microscope. In the writing routine, five-level bits are created by associating different bit values to different birefringence directions, induced i…
A series of Al complexes containing phenoxyimine ligands of the types R 1 (R 2 )Al[O-2- t Bu-6-{(C 6 F 5 )N═CH}C 6 H 3 ] [R 1, R 2 = Me, Me ( 1a ); Et, Et ( 1b ); Me, Cl ( 1c )] and Me 2 Al[O-2- t Bu-6-(ArN═CH)C 6 H 3 ] [Ar = 2,6-F 2 C 6 H 3 ( 2a ), 2,4-F 2 C 6 H 3 ( 3a ), 3,4-F 2 C 6 H 3 ( 4a )] have been prepared an…
Scanning tunneling microscopy and density functional theory studies show that oxygen adatoms (${\mathrm{O}}_{a}$), produced during ${\mathrm{O}}_{2}$ exposure of reduced ${\mathrm{TiO}}_{2}(110)$ surfaces, alter the water dissociation and recombination chemistry through two distinctive pathways. Depending on whether $…
We present a novel nuclear targeting nanoprobe based on peptide functionalized gold nanoparticles and its surface-enhanced Raman scattering (SERS) in living cells. For the first time, we probe an original SERS signal from the living cell nucleus by using high-selectivity functionalized gold nanoparticles. The gold nan…
