Amplitude modulation in infrared metamaterial absorbers based on electro-optically tunable conducting oxides
(
Springer Verlag
, 2018 , Article)
A class of electro-optically tunable metamaterial absorbers is designed and theoretically investigated in the infrared regime towards realizing free-space amplitude modulators. The spacer between a subwavelength metallic ...
Discrimination of breast cancer from benign tumours using Raman spectroscopy
(
Public Library of Science
, 2019 , Article)
Breast cancer is the most common cancer among women worldwide, with an estimated 1.7 million cases and 522,000 deaths in 2012. Breast cancer is diagnosed by histopathological examination of breast biopsy material but this ...
Catalytic Degradation of 4-Ethylpyridine in Water by Heterogeneous Photo-Fenton Process
(
MDPI
, 2019 , Article)
In this work, the degradation of 4-ethylpyridine (4EP) in water by a heterogeneous photo-Fenton process (H2O2/Fe3O4/ultraviolet irradiation (UV)) was investigated. More rapid and effective 4EP degradation was obtained with ...
Sub-Femtojoule Hybrid Plasmonic Optical Modulator
(
Institute of Electrical and Electronics Engineers Inc.
, 2019 , Article)
A highly compact optical modulator is proposed and analyzed. The modulator is based on the hybrid plasmonic waveguide platform. The structure of the modulator is built from silicon, silver, and electro-optical polymer ...
Polymerization of 3-cyanopropyl (triethoxy) silane: A kinetic study using gas chromatography
(
John Wiley and SonsInc.
, 2018 , Article)
Gas chromatography (GC) was used to study the kinetics of the 3-cyanopropyl triethoxysilane (CTES) polymerization. The reaction is a consecutive complex reaction that depends mainly on the kinetics of the first hydrolyzed ...
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 ...
