Characterization and compression properties of injection molded carbon nanotube composites
Authors: Curtzwiler G. , Singh J. , Miltz J. , Doi J. , Vorst K.
Published: March 2008

Since the development of carbon nanotubes (CNTs) in 1991, they have received much attention with improved mechanical, thermal, and electrical properties of their composites compared to common polymer composites. The CNTs are currently used to increase the modulus of common thermoplastics and thermosets, including urethanes and epoxies. The CNTs are difficult to disperse within any media because of limited chemical reactivity and potential agglomeration in their “as grown” state. This study evaluated the effect of incorporating bundled and unbundled CNTs at different concentrations into Polyurethane/CNT/woven fiber reinforced composites. Optical microscopy and atomic force microscopy (AFM) characterized the dispersion of CNTs within the polymer matrix in injection molded CNT/polyurethane composites. Polyurethane/CNT/woven fiber reinforced composite plaques were prepared and then characterized by mechanical compression testing. Optical microscopy and AFM qualitatively determined a decreased agglomerate size resulting in improved mechanical properties. Results of this study show significant differences in yield stress, stress at failure, and modulus of elasticity within the various treatments. No significant differences were found for yield strain, strain at failure, and toughness. However, the conservativeness of the statistical model warrants further investigation for strain at failure and toughness with possible interaction effects of CNT concentration for each composite. © 2008 Wiley Periodicals, Inc.

Effects of bulk morphology on the mechanical properties of melt‐blended PP/PS blends
Authors: Yoshida Kazuhiro , Kawamura Takanobu , Terano Minoru , Nitta Koh‐hei
Published: March 2008

We investigated the relationship between morphology and mechanical properties in binary blends of isotactic polypropylene (PP) and atactic polystyrene (PS) showing completely phase‐separated morphology. The domain size and crystallinity in PP phase were controlled by the comp‐molding conditions such as holding time in the hot‐press and quenching temperature to prepare the sheets. The phase‐inversion took place at 62.5 wt % of PS content and this leads to ductile‐brittle transition at the blend composition. It was found that the mechanical properties of PP‐rich blends are dominantly affected by the nature of the PP matrix and independent of the domain size of PS phase. This is associated with the interfacial separation between rigid PS droplets and PP matrix. © 2008 Wiley Periodicals, Inc. J Appl Polym Sci, 2008
Determinants of borrowing demand from Norwegian local public libraries
Authors: Løyland Knut , Ringstad Vidar
Published: March 2008

The main purpose of this article is to explore the determinants of book borrowing demand from local public libraries in Norway, using balanced panel data for the period 2001–2004. The more striking results of these calculations show the basic differences between children and adults in the effects of main borrowing determinants. While income is quite important and the shadow price is quite unimportant for children, the opposite is true for adults. A likely explanation of this finding is that the real shadow price is higher for adults and that it is also higher in communities with high income levels. It was found that both stock and growth of the stock are important factors for book loans as well as loans of other media. There is a basic difference, however, in the effect of books on the demand for other media as compared with the opposite cross‐effect: The book stock has a substantial and significantly negative impact on the demand for other media. The face value of this finding implies that there is actually a crowding‐out effect on other media from books, while it is usually expected to be the other way around.
Are psychiatrists affecting the legal process by answering legal questions?
Authors: Hardie Timothy , Elcock Susan , Mackay R. D.
Published: March 2008

Background Psychiatrists are often asked to answer legal questions. The extent to which they answer strictly legal rather than medical matters is not known.

Aim To investigate how strongly psychiatrists in England and Wales express opinions on one legal question – that of diminished responsibility in respect of a murder charge, and how this is related to outcome in court.

Method Our data were extracted from psychiatric reports and case files supplied by the then Department of Constitutional Affairs (now the Ministry of Justice) on cases heard in the Crown Courts between 1 January 1997 and 31 December 2001 in which the defence of diminished responsibility had been raised. The cases had been selected by the Law Commission in their earlier review of partial defences to murder. We devised a reliable system of rating the presence/absence and strength of expression of a legal opinion in the medical reports. We tested the data for relationship between nature and strength of opinion and progression to trial and verdict.

Results Psychiatric reports were available on 143 of 156 cases in which diminished responsibility was considered. They yielded 338 opinions on at least one aspect of diminished responsibility. In 110 (93%) of the 118 cases in which there was a diminished verdict, this was made without trial and, therefore, without reference to a jury. In only eight (27%) out of the 30 cases that went to trial, was a diminished responsibility verdict made. Half of the reports (169) gave a clear opinion on diminished responsibility, a third (121) invited the court to draw a particular conclusion and only 11% (36) provided relevant evidence without answering the legal questions. When there was an opinion or an invitation to make a finding on the legal question, a trial was less likely. A trial was also less likely if reports agreed on what the verdict should be.

Conclusions Psychiatrists frequently answer the legal question of diminished responsibility. The judiciary and medical experts should join in research to examine the consequences of different styles or approaches in presentation of essentially similar evidence in court.

A combined drama‐based and CBT approach to working with self‐reported anger aggression
Authors: Blacker Janine , Watson Andy , Beech Anthony R.
Published: March 2008

Background A drama‐based programme, called ‘Insult to Injury’, was designed to explore the processes of anger, aggression and violence. The aim of the programme was to enable offenders to identify and generate strategies and skills for dealing with potentially volatile situations, and to provide a safe and supportive environment in which to practice and evaluate these strategies.

Aims An active drama‐based approach combined with cognitive‐behavioural techniques was used to explore issues such as masculinity, power and control, pride and shame and victim awareness. Reductions in anger were hypothesized.

Method A single group pre/post design assessed the levels of anger before and after the course.

Results Sixty‐two adult male offenders from six prison establishments in the UK took part in the nine‐day course. As hypothesised, significant reductions in anger were found in pre‐ to post‐course assessment.

Conclusions These results suggest that a drama‐based approach may be a promising adjunct to traditional anger management programmes for violent offenders. Copyright © 2008 John Wiley & Sons, Ltd.
Bonding in Tropolone, 2‐Aminotropone, and Aminotroponimine: No Evidence of Resonance‐Assisted Hydrogen‐Bond Effects
Authors: Sanz Pablo , Mó Otilia , Yáñez Manuel , Elguero José
Published: March 2008

The properties of the intramolecular hydrogen bond (IMHB) in tropolone, aminotropone, and aminotroponimine have been compared with those in the corresponding saturated analogues at the B3LYP/6‐311+G(3df,2p)//B3LYP/6‐311+G(d,p) level of theory. In general, all those compounds in which the seven‐membered ring is unsaturated exhibit a stronger IMHB than their saturated counterparts. Nevertheless, this enhanced strength is not primarily due to resonance‐assisted hydrogen‐bond effects, but to the much higher intrinsic basicity and acidity of the hydrogen‐bond acceptor and donor groups, respectively, in the unsaturated compounds. These acidity and basicity enhancements have a double origin: 1) the unsaturated nature of the moiety to which the hydrogen‐bond donor and acceptor are attached and 2) the cyclic nature of the compounds under scrutiny. As has been found for hydroxymethylene and aminomethylene cyclobutanones, and cyclobutenones and their nitrogen‐containing analogues, the IMHB strength follows the [donor, acceptor] trend: [OH, CNH]>[OH, CO]>[NH2, CNH]>[NH2, CO] and fulfills a Steiner–Limbach correlation similar to that followed by intermolecular hydrogen bonds.
Energy Migration in a Self‐Assembled Nonameric Porphyrinic Molecular Box
Authors: Flamigni Lucia , Ventura Barbara , Oliva Ana I. , Ballester Pablo
Published: March 2008

We describe the construction of self‐assembled double‐decker porphyrin arrays built up from two covalently connected trimeric Zn–porphyrin units that are joined together by metal‐coordination bonds with diamine ligands. We used three different types of diamine ligands: 1,4‐diaza[2.2.2]bicyclooctane (DABCO), 4,4′‐bipyridine (BIPY), and 5,15‐bis(4‐pyridyl)‐10,20‐diphenylporphyrin (DPYP). The ligands act as pillars, through two axial coordination bonds with the porphyrinic ZnIIions, to block the planes of the porphyrin units in an almost cofacial orientation and inducing the formation of a trigonal prismatic structure. The spectroscopic and photophysical properties of the Zn–trisporphyrin component were determined as well as those of the resulting multimolecular cagelike assemblies. The double‐decker assembly with DPYP as the pillars constitutes a nonameric porphyrin aggregate. Although this assembly is thermodynamically less stable than those containing DABCO or BIPY, efficient photoinduced energy transfer occurs (96 % yield) from the trisporphyrin base units to the DPYP side walls. The rate of the energy‐transfer process is in good agreement with that calculated for a dipole–dipole (Förster) mechanism corrected for the unfavorable orientation geometry of the donor and the axially bound acceptor.

Photoconduction in Amorphous Organic Solids
Authors: Hertel Dirk , Bässler Heinz
Published: March 2008

Herein, we focus on the principles of photoconduction in random semiconductors—the key processes being optical generation of charge carriers and their subsequent transport. This is not an overview of the current work in this area, but rather a highlight of elementary processes, their involvement in modern devices and a summary of recent developments and achievements. Experimental results and models are discussed briefly to visualize the mechanism of optical charge generation in pure and doped organic solids. We show current limits of models based on the Onsager theory of charge generation. After the introduction of experimental techniques to characterize charge transport, the hopping concept for transport in organic semiconductors is outlined. The peculiarities of the transport of excitons and charges in disorderd organic semiconductors are highlighted. Finally, a short discussion of ultrafast transport and single chain transport completes the review.
Thin‐Film Properties of DNA and RNA Bases: A Combined Experimental and Theoretical Study
Authors: Haug Andrea , Schweizer Sabine , Latteyer Florian , Casu Maria Benedetta , Peisert Heiko , Ochsenfeld Christian , Chassé Thomas
Published: March 2008

The structures of the DNA and RNA bases cytosine, uracil, and thymine in thin films with a nominal film thickness of about 20 nm are studied by using X‐ray photoemission spectroscopy (XPS) and Fourier‐transform infrared spectroscopy. The molecules are evaporated in situ from powder on a gold foil. The experimental results indicate that cytosine is composed of two energetically close tautomeric forms, whereas uracil and thymine exist in only one tautomeric form. Additionally, quantum chemical calculations are performed to complement the experimental results. The relative energies of the tautomeric forms of cytosine, uracil, and thymine are calculated using Hartree–Fock (HF), density functional theory (DFT), and post‐HF methods. Furthermore, the assignment of the XPS spectra is supported by using simple model considerations employing Koopmans ionization energies and Mulliken net atomic charges.
Ordered Mesoporous Thin Films of Rutile TiO2 Nanocrystals Mixed with Amorphous Ta2O5

Published: March 2008

Ordered mesoporous thin films of composites of rutile TiO2 nanocrystals with amorphous Ta2O5 are fabricated by evaporation‐induced self‐assembly followed by subsequent heat treatment beyond 780 °C. Incorporation of selected amounts of Ta2O5 (20 mol %) in the mesoporous TiO2 film, together with the unique mesoporous structure itself, increased the onset of crystallization temperature which is high enough to ensure the crystallization of amorphous titania to rutile. The ordered mesoporous structure benefits from a block‐copolymer template, which stabilizes the mesostructure of the amorphous mixed oxides before crystallization. The surface and in‐depth composition analysis by X‐ray photoelectron spectroscopy suggests a homogeneous intermixing of the two oxides in the thin film. A detailed X‐ray absorption fine structure measurement on the composite film containing 20 mol % Ta2O5 and heated to 800 °C confirms the amorphous nature of the Ta2O5 phase. Photocatalytic activity evaluation suggests that the rutile nanocrystals in the synthesized ordered mesoporous thin film possess good ability to assist the photodegradation of rhodamine B in water under illumination by UV light.
Probing Innovative Microfabricated Substrates for their Reproducible SERS Activity

Published: March 2008

New types of microfabricated surface‐enhanced Raman spectroscopy (SERS) active substrates produced by electron beam lithography and ion beam etching are introduced. In order to achieve large enhancement factors by using the lightning rod effect, we prepare arrays consisting of sharp‐edged nanostructures instead of the commonly used dots. Two experimental methods are used for fabrication: a one‐stage process, leading to gold nanostar arrays and a two‐stage process, leading to gold nanodiamond arrays. Our preparation process guarantees high reproducibility. The substrates contain a number of arrays for practical applications, each 200×200 μm2in size. To test the SERS activity of these nanostar and nanodiamond arrays, a monolayer of the dye crystal violet is used. Enhancement factors are estimated to be at least 130 for the nanodiamond and 310 for the nanostar arrays.
Organelle Tracking in a Living Cell with Microsecond Time Resolution and Nanometer Spatial Precision

Published: March 2008

The study of cellular processes such as organelle transport often demands particle tracking with microsecond time‐resolution and nanometer spatial precision, posing significant challenges to existing tracking methods. Here, we have developed a novel strategy for two‐dimensional tracking of gold nanoparticles (GNPs) with 25 μs time resolution and ∼1.5 nm spatial precision, by using a quadrant photodiode to record the positions of GNPs in an objective‐type dark‐field microscope. In combination with a feedback loop, this technique records long, high time‐resolution and spatial precision trajectories of endocytosed GNPs transported by the molecular motors kinesin and dynein in a living cell. In the full range of organelle velocities (0–8 μm s−1), we clearly resolve the individual 8 nm steps of cargoes carried by kinesin, and the 8, 12, 16, 20, and 24 nm steps of those carried by dynein. These experiments yield new information about molecular motor stepping in living cells.
Cytometric fingerprinting: Quantitative characterization of multivariate distributions

Published: March 2008

Recent technological advances in flow cytometry instrumentation provide the basis for high‐dimensionality and high‐throughput biological experimentation in a heterogeneous cellular context. Concomitant advances in scalable computational algorithms are necessary to better utilize the information that is contained in these high‐complexity experiments. The development of such tools has the potential to expand the utility of flow cytometric analysis from a predominantly hypothesis‐driven mode to one of discovery, or hypothesis‐generating research. A new method of analysis of flow cytometric data called Cytometric Fingerprinting (CF) has been developed. CF captures the set of multivariate probability distribution functions corresponding to list‐mode data and then “flattens” them into a computationally efficient fingerprint representation that facilitates quantitative comparisons of samples. An experimental and synthetic data were generated to act as reference sets for evaluating CF. Without the introduction of prior knowledge, CF was able to “discover” the location and concentration of spiked cells in ungated analyses over a concentration range covering four orders of magnitude, to a lower limit on the order of 10 spiked events in a background of 100,000 events. We describe a new method for quantitative analysis of list‐mode cytometric data. CF includes a novel algorithm for space subdivision that improves estimation of the probability density function by dividing space into nonrectangular polytopes. Additionally it renders a multidimensional distribution in the form of a one‐dimensional multiresolution hierarchical fingerprint that creates a computationally efficient representation of high dimensionality distribution functions. CF supports both the generation and testing of hypotheses, eliminates sources of operator bias, and provides an increased level of automation of data analysis. © 2008 International Society for Advancement of Cytometry
A Phosphanyl‐Substituted Benzo‐1,3,2‐Dioxaborol as Ambiphilic Bifunctional Lewis Donor–Acceptor Unit

Published: March 2008

Condensation of 3‐[(diphenylphosphanyl)methyl]benzene‐1,2‐diol (1) with phenyl boronic acid gave a phosphane‐functionalised benzo‐1,3,2‐dioxaborol 3. The ability of this species to act as a Lewis base through the P‐centered donor and as a Lewis acid through the B‐centered acceptor sites was demonstrated by the reactions with (cod)PdCl2 and some nitrogen donors (4‐dimethylaminopyridine, diaza‐[2.2.2]‐bicyclooctane, pyridine). These reactions yielded either palladium–phosphane complexes or amine–borane adducts that were characterised by spectroscopic data and, in some cases, by single‐crystal X‐ray diffraction studies. Reactions of a Pd complex of the phosphane‐functionalised benzo‐1,3,2‐dioxaborol 3 with dabco, or of the dmap adduct of 3 with (cod)PdCl2, gave materials that were characterised by analytical data and solid‐state NMR spectroscopic data as triple Lewis acid/base complexes and that contain both P→Pd and B←N dative bonds. Even though these adducts were unstable in solution, the results of these experiments demonstrate the ability of 3 to act as a bifunctional donor/acceptor ligand, which is of potential use as a building block for main chain organometallic polymers or multimetallic complexes.(© Wiley‐VCH Verlag GmbH & Co.
