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, ...
CMOS compatible silicon slot ring resonator sensor
(
SPIE
, 2019 , Conference Paper)
We propose a fully CMOS compatible optical sensor based on the ring resonator mechanism. The waveguide structure of the sensor utilizes the silicon on insulator slot waveguide configuration. The analyte fills the slot and ...
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 ...
Curcumin a Colorimetric and Fluorimetric Cyanide Probe in Aqueous System and Living Cells
(
Royal Society of Chemistry
, 2019 , Article)
Curcumin, 1,7-bis(4-hydroxy-3-methoxyphenyl)-1,6-hepta-diene-3,5-dione, is a natural product obtained from the rhizome of Curcuma longa. Curcumin has been demonstrated to be a strong antioxidant with anticancer properties ...
Investigation of Biochemical Alterations in Ischemic Stroke Using Fourier Transform Infrared Imaging Spectroscopy-A Preliminary Study.
(
MDPI
, 2019 , Article)
Brain damage, long-term disability and death are the dreadful consequences of ischemic stroke. It causes imbalance in the biochemical constituents that distorts the brain dynamics. Understanding the sub-cellular alterations ...
The electronic origin of the ground state spectral features and excited state deactivation in cycloalkanones: the role of intermolecular H-bonding in neat and binary mixtures of solvents
(
NLM (Medline)
, 2019 , Article)
In this study, a D-A cycloalkanone (K1) has been investigated by steady state absorption and fluorescence in neat solvents and in three binary mixtures of nonpolar aprotic/polar protic, polar aprotic/polar protic, and polar ...
Enhanced photocatalytic performance of WON@porous TiO2 nanofibers towards sunlight-assisted degradation of organic contaminants
(
Royal Society of Chemistry
, 2018 , Article)
In the last few decades, TiO2 has been widely used in different types of photocatalytic applications. However, the relatively large optical band gap (∼3.2 eV), low charge carrier mobility and consequently its low quantum ...
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, ...
