AbstractBackgroundThere is a wealth of evidence detailing gray matter degeneration and loss of cognitive function over time in individuals with Huntington's disease (HD). Efforts to attenuate disease‐related brain and cognitive changes have been unsuccessful to date. Multidisciplinary rehabilitation, comprising motor and cognitive intervention, has been shown to positively impact on functional capacity, depression, quality of life and some aspects of cognition in individuals with HD. This exploratory study aimed to evaluate, for the first time, whether multidisciplinary rehabilitation can slow further deterioration of disease‐related brain changes and related cognitive deficits in individuals with manifest HD.MethodsFifteen participants who manifest HD undertook a multidisciplinary rehabilitation intervention spanning 9 months. The intervention consisted of once‐weekly supervised clinical exercise, thrice‐weekly self‐directed home based exercise and fortnightly occupational therapy. Participants were assessed using MR imaging and validated cognitive measures at baseline and after 9 months.ResultsParticipants displayed significantly increased gray matter volume in the right caudate and bilaterally in the dorsolateral prefrontal cortex after 9 months of multidisciplinary rehabilitation. Volumetric increases in gray matter were accompanied by significant improvements in verbal learning and memory (Hopkins Verbal Learning‐Test). A significant association was found between gray matter volume increases in the dorsolateral prefrontal cortex and performance on verbal learning and memory.ConclusionsThis study provides preliminary evidence that multidisciplinary rehabilitation positively impacts on gray matter changes and cognitive functions relating to verbal learning and memory in individuals with manifest HD. Larger controlled trials are required to confirm these preliminary findings.
Palladium Nanoparticles Supported on Highly Oriented Pyrolytic Graphite: Preparation, Reactivity and Stability

Published: January 2015

AbstractPalladium nanoparticles (Pd NPs) were deposited electrochemically on highly oriented pyrolytic graphite (HOPG) substrates by using a potentiostatic double‐pulse technique. The particle densities were in the order of 109 cm−2; the radius of the deposited Pd NPs (2–20 nm) was proportional to the 1/3 power of the growth pulse duration (tg1/3). The open‐circuit potential measured during potentiodynamic potential scans of hydrogen evolution/oxidation (HER/HOR) at Pd/HOPG electrodes (average radii of Pd NPs larger than 8 nm) was more negative than at a bulk Pd electrode; this was caused by the different phases of palladium hydride (PdHx) formed in the latter case. Pd/HOPG samples showed an increased specific current density with decreasing particle size in HER. The activity of Pd NPs for HER is primarily affected by the absorbed‐hydrogen‐atom content in the Pd lattice. The electrochemical activity of Pd NPs for the oxygen reduction reaction (ORR) in acidic media decreased for smaller particle sizes. The stability of the Pd NPs was significantly influenced by the pH of the electrolyte. Pd NPs had a higher dissolution rate in solution with lower pH. The degeneration mechanisms seen for Pd NPs on HOPG were the dissolution of metal atoms, detachment of particles, and particle agglomeration. Corrosion of the graphite substrate after the potential cycles was also observed in AFM images.

Synthesis and Electrochromic Properties of Conducting Polymers Based on Highly Planar 2,7‐Disubstituted Xanthene Derivatives
Authors: Olech Kamila , Gutkowski Ramona , Kuznetsov Volodymyr , Roszak Szczepan , Sołoducho Jadwiga , Schuhmann Wolfgang 
Published: January 2015

AbstractOn the basis of preliminary DFT calculations, p‐type semiconducting polymers based on 2,7‐substituted xanthene building blocks that show a high degree of planarity were designed. The synthesis, electrochemical characterization, and theoretical modeling of 2,7‐bis(thiophen‐2‐yl)‐9,9‐dimethylxanthene (1) and 2,7‐bis(3‐hexylthiophen‐2‐yl)‐9,9‐dimethylxanthene (2) is described. The synthetic procedure is based on the incorporation of thiophene rings by means of Pd‐catalyzed cross‐coupling reactions, which lead to monomers 1 and 2. Copolymers P1 and P2 obtained by means of anodic polymerization have been characterized by spectroscopic and electrochemical methods. Electrochromism was observed for both polymers. The experimental data supported by density functional theory modeling explain the influence of alkyl chain substitution on the properties of the investigated copolymers.
Iron Oxide Supported Sulfhydryl‐Functionalized Multiwalled Carbon Nanotubes for Removal of Arsenite from Aqueous Solution

Published: January 2015

AbstractMagnetic iron oxide/carbon nanotube (MI–CNT) hybrids have been successfully synthesized through a simple solid‐phase method by using as‐prepared CNTs (APCNTs). To further enhance the adsorption capacity for AsIII, MI–CNTs were subsequently functionalized by using an amino acid derivative (glutathione (GSH)) through a facile chemical route. CNTs not only act as a support for iron oxide but also significantly contribute to arsenic removal. The resulting GMI–CNTs possess simultaneously a high adsorption capacity and desirable magnetic properties, thus making them promising for use as an adsorbent to remove AsIII with significantly enhanced adsorption capacity (19.12 mg g−1) and desired magnetic separation properties (Ms=27.3 emu g−1). Adsorption studies indicated that the active sites on the surface of GMI–CNTs for AsIII are heterogeneous owing to the multiphase of Fe and the GSH functionalization. Therefore GMI–CNTs can potentially be used as a practical adsorbent for the decontamination of AsIII in water. The results of this study are highly important for practical applications of as‐prepared CNTs that contain catalyst nanoparticles.
Controlled Synthesis of Monodispersed Sub‐50 nm Nanoporous In2O3 Spheres and Their Photoelectrochemical Performance
Authors: Liu Qi , Zhang Wen , Liu Rongmei , Mao Guobing 
Published: January 2015

AbstractUniform nanoporous In2O3 nanospheres with high surface areas were synthesized through a simple solvothermal route with ethylenediamine (en) as the solvent. The prepared In2O3 nanospheres with diameters about 50 nm are composed of many nanoparticles with average sizes of ca. 5 nm. The unique nanospheres inherit both the large surface areas of the nanoparticles and the high crystallinity of bulky materials. The introduction of water or some other solvents into the reaction solution results in the formation of InOOH and In(OH)3 particles indicating that en is indispensable for synthesis of In2O3 with a nanoporous nanosphere structure. UV/Vis spectroscopy reveals that the band‐gap of synthesized In2O3 nanospheres is about 2.95 eV, mostly close to that of the single‐crystalline bcc‐In2O3. The PL spectrum of the In2O3 nanospheres shows two emission peaks located at 470 nm and 483 nm. The photocurrent of the prepared In2O3 electrodes by electrophoretic deposition strongly depends on the calcination temperature. The highest photocurrent density up to 1.9 mA cm–2 at 0.65 V (vs. Ag/AgCl) in 0.1 M Na2SO4 aqueous solution was recorded in the sample annealed at 550 °C. The high photocatalytic activity of the In2O3 nanospheres can be attributed to the high surface area, and the large number of nanopores in the In2O3 nanospheres.
