Thermal, Mechanical and Electrical Studies of Novel Shape Memory Polyurethane/Polyaniline Blends

引用

Chinese Journal of Polymer Science 2015年第9期33卷 1313-1324页

作者： rabia Sattar Ayesha Kausar Muhammad Siddiq Department of Chemistry Quaid-i-Azam University Nanosciences and Catalysis Division National Centre for Physics Quaid-i-Azam University Campus

Shape memory polymer （SMP） blends based on polyurethane （PU） and polyaniline （PANI） were prepared via chemical in situ polymerization process. The thermal, mechanical, electrical and shape memory properties were investigated. The structural characterization and morphology of the polymer blends were inspected by Fourier transform infrared （FTIR） and scanning electron microscopy （SEM）, respectively. The 1 wt% of PANI loading enhanced the thermal stability of the system up to 339 ~C. According to differential scanning calorimetry （DSC）, the glass transition temperature （Tg） and melting temperature （Tm） of PU/PANI blends increased with the polyaniline loading （0.1 wt%-l wt%）. Improved mechanical properties such as tensile strength and Young＇s modulus of PU matrix were also observed with PANI. Moreover, the electrical conductivity of PU/PANI blends was also found to be a function of PANI loading. Remarkable recoverability of thermally triggered shape memory （SM） behavior to the extent of 96% was achieved for 1 wt% PANI blend.

Extraskeletal symptoms and comorbidities of diffuse idiopathic skeletal hyperostosis

引用

World Journal of Clinical Cases 2014年第9期2卷 422-425页

作者： rabia Terzi Derince Training and Research Hospital Department of Physical Medicine and RehabilitationKocaeli 41 300 Turkey

Diffuse idiopathic skeletal hyperostosis(DISH) is a noninflammatory disease characterized by calcification and ossification of soft tissues, mainly enthesis and spinal ligaments. The clinical presentation primarily includes spinal involvement-induced pain and range of motion. Although rare, life-threatening gastrointestinal, respiratory or neurological events or severe morbidity due to bone compression on the adjacent structures may develop. There is a limited amount of data on DISHrelated events in the literature. In recent years, comorbid metabolic disorders are of great interest in patients with DISH. The early diagnosis of these conditions as well as rare entities allows an effective multidisciplinary approach for the treatment of DISH. In this article, we review extraskeletal symptoms and associated comorbidities in patients with DISH.

Plasmon mediated entanglement dynamics of distant quantum dots

We investigate the time evolution of entanglement between two quantum dots in an engineered vacuum environment such that a metallic nanoring having a surface plasmon is placed near the quantum dots. Such engineering in environment results in oscillations in entanglement dynamics of the quantum dots systems. With proper adjustment of the separation between the quantum dots, entanglement decay can be stabilized and preserved for longer time than its decay without the surface plasmons interactions.

Direct oxidation of methane to oxygenates over heteropolyanions

引用

Journal of Natural Gas Chemistry 2008年第3期17卷 309-312页

作者： Ouarda Benlounes Sadia Mansouri Chérifa rabia Smain Hocine Laboratoire de Chimie Appliqueé et de Génie Chimique Université Mouloud Mammeri Laboratoire de Chimie du Gaz Naturel Institut de Chimie USTHB

Partial oxidation of methane to formaldehyde and methanol was studied at atmospheric pressure in the temperature range of 700-750 °C using heteropolycompound catalysts （NH4）6HSiMo11FeO40, （NH4）4PMo11FeO39, and H4PMo11VO40, which were prepared and characterized by various analysis techniques such as infrared, visible UV, XRD and DTA. O2 or N2O was used as the oxidizing agent, and the principal products of the reaction were CH3OH, CH2O, CO, CO2, and water. The conversion and the selectivity of products depend strongly on the reaction temperature, the nature of oxidizing agent, and the composition of catalyst.
