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, ...
Fourier Transform Infrared (FT-IR) and Laser Ablation Inductively Coupled Plasma–Mass Spectrometry (LA-ICP-MS) Imaging of Cerebral Ischemia: Combined Analysis of Rat Brain Thin Cuts Toward Improved Tissue Classification
(
SAGE Publications Inc.
, 2018 , Article)
Microspectroscopic techniques are widely used to complement histological studies. Due to recent developments in the field of chemical imaging, combined chemical analysis has become attractive. This technique facilitates a ...
Efficient degradation of tannic acid in water by UV/H2O2 process
(
Chinese Institute of Environmental Engineering
, 2018 , Article)
In this work, the degradation of tannic acid (TA) by UV/H2O2 process has been investigated. UV/H2O2 oxidation experiments were performed by UV irradiation at 254 nm of TA aqueous solutions in a photo-reactor. Firstly, 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). ...
