Carbon Nanotubes Dosage Optimization for Strength Enhancement of Cementitious Composites
(
Elsevier
, 2019 , Conference Paper)
Concrete is the most common used material for construction in Qatar as well as in the world. Exposure to sever environmental conditions causes physical deterioration of concrete structures and significantly affect the ...
Environmental degradation of 30 to 50 years old reinforced concrete structures in Qatari climate
(
Advanced Engineering Solutions
, 2017 , Conference Paper)
This paper presents the results of a field survey carried out on three reinforced concrete (RC) structures built respectively in 1960's 1970's and 1980's to determine the main load (environmental) and resistance (concrete ...
On secure communication over the Z-Channel
(
Institute of Electrical and Electronics Engineers Inc.
, 2017 , Conference Paper)
The discrete memoryless Z-Channel (DM-ZC) with a confidential cross-message is considered. Three messages are transmitted; encoder 1 transmits one message to be decoded by decoder 1. Encoder 2 transmits two messages, the ...
Novel Ni-B/AlN nanocomposite coatings for oil and gas industry
(
National Assoc. of Corrosion Engineers International
, 2018 , Conference Paper)
Corrosion is a major cause of materials and equipment failure in the oil and gas industry, and its prevention is crucial to ensure reliability of the assets. Towards, this goal, Ni-B/AlN nanocomposite coatings were synthesized ...
Experimental characterization of a tactile sensor for surgical applications
(
Institute of Electrical and Electronics Engineers Inc.
, 2018 , Conference Paper)
© 2018 IEEE. This paper presents an improved piezoelectric sensor fabricated using reduced graphene oxide (rGO)-filled polydimethylsiloxane (PDMS) elastomer composite that is able to sense the linear force applied onto its ...
Nickel oxide carbon nanofiber composite for electrochemical oxidation of methanol
(
Electrochemical Society Inc.
, 2014 , Conference Paper)
Electrospun fibers of a mixture of polyvinylpyrrolidone (PVP), polyaniline (PANI) and graphene were stabilized for 2 h at 200 °C and then carbonized at 800 °C for 5 h. Composites were prepared by depositing Ni(OH)2 on the ...
Characterizing biaxially stretched polypropylene/graphene nanoplatelet composites
(
International Committee on Composite Materials
, 2017 , Conference Paper)
During moulding processes such as thermoforming and blow moulding, heated polymer materials are subjected to rapid biaxial deformation as they are drawn into the shape of a mould. It is therefore essential to accurately ...
Antibacterial Modification Of Polyethylene By Multistage Process Utilizing Low-temperature Plasma
(
Hamad bin Khalifa University Press (HBKU Press)
, 2014 , Conference Paper)
Limiting factor of PE application in healthcare is high susceptibility of polyethylene towards bacterial growth. For this reason, antibacterial treatment of PE foils using appropriate antibacterial agents was used in this ...
Usefulness of In-Situ Synchrotron Study on Scale Formation during CO2 Corrosion of Mild Steel: A Review
(
Hamad bin Khalifa University Press (HBKU Press)
, 2016 , Conference Paper)
Despite the availability of the detailed knowledge about the chemical, electrochemical and transport processes associated with the formation of ferrous carbonate during CO2- corrosion of mild steel, information available ...
Atmospheric Corrosion Behavior of Al 6xxx Alloys in Qatar State
(
Hamad bin Khalifa University Press (HBKU Press)
, 2016 , Conference Paper)
Al 6000 series [Al-Mg-Si-Cu] are widely used in oil field for frames, tanks, pipelines and machinery applications. They showed a relatively high corrosion resistant, thermal and electrical conductivity and low cost. ...
