Pierre Audebert、Saı̈d Sadki、Fabien Miomandre 等 5 位作者2003-04-09New Journal of Chemistry

We describe the first easy syntheses of new fully conjugated monomers and their derived polymers containing a photoisomerizable azobenzene group, along with their electrochemical properties. Two classes of compounds have been studied differing in the nature of the polymerizable unit: pyrrole or 2, 5-dithienylpyrrole.…

Unusual Magnetic State in Lithium-DopedMoS2Nanotubes

D. Mihailović、Zvonko Jagličić、Denis Arčon 等 12 位作者2003-04-09Physical Review Letters

We report on the very peculiar magnetic properties of an ensemble of very weakly coupled lithium-doped MoS2 nanotubes. The magnetic susceptibility chi of the system is nearly 3 orders of magnitude greater than in typical Pauli metals, yet there is no evidence for any instability which would alleviate this highly frust…

Surface Sites of Pd/CeO2/Al2O3 Catalysts in the Partial Oxidation of Propane

André Luis de Alcantara Guimarães、L.C. Dieguez、Martín Schmal2003-04-09The Journal of Physical Chemistry B

Propane oxidation was studied on a Pd-supported Al 2 O 3 catalyst promoted by ceria, when this ceria was first grafted as a monolayer over alumina. The reaction proceeded under different feed conditions, and the surface sites were identified by X-ray photoelectron spectroscopy (XPS) in a pretreatment chamber and then…

Multiple Ordering Transitions: Hierarchical Self‐Assembly of Rod–Coil Block Copolymers

Ji‐Woong Park、Edwin L. Thomas2003-04-09Advanced Materials

Organized structures over length scales differing by 10 3 are reported, i.e., crystals of rod block (unit cell ∼ 1 nm), block copolymer microdomains (layer periodicity ∼ 50 nm), and Néel domain walls (wall periodicity ∼ 1000 nm)—see Figure and inside front cover. The result is an example of combined dynamic and static…

Adsorption and Dimerization of NO Inside Single-Walled Carbon NanotubesAn Infrared Spectroscopic Study

Oleg Byl、Petro Kondratyuk、John T. Yates2003-04-09The Journal of Physical Chemistry B

The physical adsorption of NO on purified single-walled carbon nanotubes was investigated at low temperatures by means of transmission infrared spectroscopy. Ozone treatment followed by annealing was used as the method of opening the entry ports for adsorption into the interior of the nanotubes. The IR spectra show th…

An Acid–Base Controlled Molecular Switch. syn–anti Conformational Switching in a μ-oxo Bis(Iron Porphyrin)

Guy A. Hembury、Victor Borovkov、Juha M. Lintuluoto 等 4 位作者2003-04-09Chemistry Letters

Abstract It was found that FeD adopted a stable syn conformation as a result of the inclusion of atomic oxygen in a μ-oxo fashion, but on exposure to acidic conditions converted into the extended anti form. When this was subsequently made basic the syn conformation was re-adopted, simply due to re-inclusion of atomic…

Excellent Wave Absorption by Zirconium‐Based Bulk Metallic Glass Composites Containing Carbon Nanotubes

Zan Bian、R.J. Wang、M. X. Pan 等 5 位作者2003-04-09Advanced Materials

Bulk metallic glass composites containing carbon nanotubes (CNTs) are reported (see Figure). The composites are found to have strong ultrasonic wave‐absorption abilities, which increase dramatically with increasing volume fraction of CNTs. This ability implies that such composites, besides their excellent mechanical p…

Nonlinear response of a dipolar system with rotational diffusion to an oscillating field

B. U. Felderhof、R.B. Jones2003-04-09Journal of Physics Condensed Matter

The rotational diffusion equation for a dipole in the presence of an oscillating field is solved by expansion of the orientational distribution function in terms of Legendre polynomials and harmonics. The nonlinear response of the average dipole moment is studied as a function of field strength and frequency. Outside…

Infrared Detectors with Poly(3,4‐ethylenedioxy thiophene)/Poly(styrene sulfonic acid) (PEDOT/PSS) as the Active Material

Stefan C. J. Meskers、J. K. J. van Duren、René A. J. Janssen 等 5 位作者2003-04-09Advanced Materials

Fast‐response large‐area plastic infrared detectors (see Figure (Wheatstone bridge configuration)) made from a conducting PEDOT/PSS film achieve a detectivity close to 10 5 cm √Hz W –1 at 1.18 eV. The nanosecond response arises from the direct absorption of infrared light by the charge carriers on the polymer chain. T…

Field‐Induced Formation of the Polar SmCP Phase above the SmCP–Isotropic Transition

W. Weißflog、Martin Schröder、Siegmar Diele 等 4 位作者2003-04-09Advanced Materials

The field‐induced formation of an antiferroelectric “banana mesophase” (SmCP A ), which can be observed at up to 9 K above the transition SmCP → isotropic, is reported. This behavior may be due to the existence of ferroelectric clusters already in the isotropic liquid that are aligned by means of the external electric…

Tatyana Brankova、Vlasoula Bekiari、Panagiotis Lianos2003-04-09Chemistry of Materials

Hybrid organic/inorganic sol−gel materials have been synthesized by carboxylic acid solvolysis of (aminopropyl)triethoxysilane or ureasil precursors. The hybrid nature of these gels is expanded with the introduction of silica esters. A main feature of the ensuing materials is the formation of hybrid organic/inorganic…

Xiaowu Fan、Chuanjun Xia、Rigoberto C. Advíncula2003-04-09Langmuir

Surface-initiated polymerization (SIP) from clay nanoparticles was compared between surface-bound mono- and bicationic free radical initiators. Distinct properties in molecular weight (MW), extent of exfoliation, and particle morphology were observed as a consequence of using two different initiator architectures. X-r…
