Tuning the electrical properties of polyaniline by copolymerization with o-bromoaniline
(
World Scientific Publishing Co. Pte Ltd
, 2017 , Article)
Polyaniline, poly(o-bromoaniline) and poly(aniline-co-o-bromoaniline)s have been prepared by chemical oxidative polymerization methods. A series of poly(aniline-co-o-bromoaniline) derivatives has been prepared by the ...
Delicate Structural Control of Si-SiOx-C Composite via High-Speed Spray Pyrolysis for Li-Ion Battery Anodes
(
American Chemical Society
, 2017 , Article)
Despite the high theoretical capacity, silicon (Si) anodes in lithium-ion batteries have difficulty in meeting the commercial standards in various aspects. In particular, the huge volume change of Si makes it very challenging ...
Synthesis, Vibrational (IR), Thermal analysis and Quantumchemical Study of a Series of Cyclic Chalcones
(
Wiley-Blackwell
, 2016 , Article)
In this work, the influence of expanding the cyclic ring (adding methylene group) on the properties of three dimethylamino chalcones derivatives (1-3), is addressed, using a combined experimental (vibrational spectra (IR), ...
Doping of Large Ionization Potential Indenopyrazine Polymers via Lewis Acid Complexation with Tris(pentafluorophenyl)borane: A Simple Method for Improving the Performance of Organic Thin-Film Transistors
(
American Chemical Society
, 2016 , Article)
Molecular doping, under certain circumstances, can be used to improve the charge transport in organic semiconductors through the introduction of excess charge carriers which can in turn negate unwanted trap states often ...
Controlled Prelithiation of Silicon Monoxide for High Performance Lithium-Ion Rechargeable Full Cells
(
American Chemical Society
, 2016 , Article)
Despite the recent considerable progress, the reversibility and cycle life of silicon anodes in lithium-ion batteries are yet to be improved further to meet the commercial standards. The current major industry, instead, ...
Gravity investigations of recent sinkholes and karst pits of Dahal Al-Hamam, State of Qatar
(
Springer Verlag
, 2016 , Article)
Gravity prospecting is a very useful geophysical technique for the investigation of karst subsurface features, in urban areas, which are a common natural hazard in several parts of the world. Gravity data were used to ...
Carbon Dioxide Solubility in Phosphonium-, Ammonium-, Sulfonyl-, and Pyrrolidinium-Based Ionic Liquids and their Mixtures at Moderate Pressures up to 10 bar
(
American Chemical Society
, 2017 , Article)
Carbon dioxide solubility in four ionic liquids (ILs) of different families with different cationic-anionic groups (tributylmethylphosphonium formate, butyltrimethylammonium bis(trifluoromethyl sulfonyl) imide, ...
Biomonitoring of Toxic Effects of Pesticides in Occupationally Exposed Individuals
(
Elsevier
, 2016 , Article)
Background Workers in pesticide manufacturing industries are constantly exposed to pesticides. Genetic biomonitoring provides an early identification of potential cancer and genetic diseases in exposed populations. The ...
Loading Rates of Dust and Metals in Residential Houses of Arid and Dry Climatic Regions
(
Taiwan Association for Aerosol Research
, 2016 , Article)
Dust samples were collected from 38 naturally ventilated houses for 12 weeks. Effects of three variables in two groups each were evaluated: proximity to traffic density (main- and side-roads), cigarettes smoking (smoking ...
Rapid microwave assisted sol-gel synthesis of CeO2 and CexSm1-xO2 nanoparticle catalysts for CO oxidation
(
Elsevier
, 2016 , Article)
CeO2 and CexSm1-xO2 nanoparticle mixed oxides have been synthesized by microwave assisted sol-gel (MW sol-gel) and conventional sol-gel synthesis carried out at 60°C (typical sol-gel) and 100°C (approaching the MW temperature). ...
