Proton conductivity and morphology of new composite membranes based on zirconium phosphates, phosphotungstic acid, and silicic acid for direct hydrocarbon fuel cells applications
(Springer, 2016-11)The effect of Phosphotungstic acid (PWA) on the proton conductivity and morphology of zirconium phosphate (ZrP), porous polytetrafluoethylene (PTFE), glycerol (GLY) composite membrane was investigated in this work. The ... -
Proton Conductivity Studies of Zirconium Silicate/Ionic Liquids Membranes for PEM Fuel Cells Applications
(2020-12)This work reports the synthesis of a novel, high-temperature composite membrane for proton exchange membrane (PEM) fuel cells. High-temperature operation (> 100oC) is preferred in PEM fuel cells as it results in better ... -
Proton-Exchange Membrane Fuel Cell Stack Model Parameters Estimation and Model Validation
(2019-04)A proton-exchange membrane fuel cell (PEMFC) is a promising, clean, and efficient power device that converts the chemical energy stored in a fuel into electricity directly. Hydrogen is supplied from an external tank and ... -

Public sector expatriation
(Springer, 2018-06-16)A public sector expatriate is an employee who is sent abroad by their organization, for an organizational mission, for a precise period of time, and expected to return to their home organization, in their home country, ... -
Public sector HRM reform: a multi-nation perspective
(International Human Resource Management Conference, 2009)The objective of this research is to describe and discuss trends in HRM practice as they have emerged in public sector organizations undertaking new management reforms over the last two decades. To do this, we reviewed ... -
Public Transportation Buses Powered By Cooking Oil
(2014-07-22)Greenhouse gases are in a continuous rise and are destroying the environment and public transportation buses contribute dramatically and are in an interrupted increase. Moreover, the world trend has been moving towards a ... -
Pushing against a future dark side for community development: An editorial call to action
(Taylor & Francis, 2023)Community Development as a journal has undergone streamlining, yet much work remains to improve the journal’s relations with its many stakeholders around the world and within the field of community development. Community ... -
Pyrene-directed growth of nanoporous benzimidazole-linked nanofibers and their application to selective CO2 capture and separation
(2012-11)A pyrene-based benzimidazole-linked polymer (BILP-10) has been synthesized by the co-condensation of 1,3,6,8-tetrakis(4-formylphenyl)pyrene and 1,2,4,5-benzenetetramine tetrahydrochloride in dimethylformamide. The use of ... -
Qualitatively Examining Self-Regulation and Affect of First-Year Writing Students
(2021-05)Many first-year university students find it challenging to navigate a new environment while also managing limited time, additional responsibilities, and an increasingly rigorous course load. Current research seeks effective ... -
The Questioning Behaviors of EFL Teachers in UAE High Schools
(2010-05)Language teachers ask many questions in their classrooms. Questioning is a very important and effective strategy for creating a communicative atmosphere at schools and promoting learning. Research in this area has investigated ... -
R&D Productivity following First-Time CIO Appointments
(American University of Sharjah, 2013-06-09)Prior studies find that firms announcing the appointment of a new chief information officer (CIO) are rewarded by stock price increases, suggesting that the market expects new CIOs to add long-term value to the firm. In ... -
Ramsey numbers of partial order graphs (comparability graphs) and implications in ring theory
(De Gruyter, 2020)For a partially ordered set(A, ≤), letGA be the simple, undirected graph with vertex set A such that two vertices a ≠ ∈ b A are adjacent if either a ≤ b or b a ≤ . We call GA the partial order graph or comparability graph ... -
Random Aerial Beamforming for Underlay Cognitive Radio with Exposed Secondary Users
(IEEE Vehicular Technology Society, 2016)In this paper, we introduce the exposed secondary users problem in underlay cognitive radio systems, where both the secondary-to-primary and primary-to-secondary channels have a Line-of-Sight (LoS) component. Based on a ... -
Rapid and convenient method for preparing masters for microcontact printing with 1–12 mm features
(American Institute of Physics (AIP), 2004)Mechanical scribing can be employed to create surfaces with recessed features. Through replica molding elastomeric copies of these scribed surfaces are created that function as stamps for microcontact printing. It is shown ... -
Rapid Separation of Bacteria from Blood - Review and Outlook
(American Institute of Chemical Engineers (AIChE), 2016)The high morbidity and mortality rate of bloodstream infections involving antibiotic‐resistant bacteria necessitate a rapid identification of the infectious organism and its resistance profile. Traditional methods based ... -
Rapid separation of bacteria from blood – Chemical aspects
(Elsevier, 2017)To rapidly diagnose infectious organisms causing blood sepsis, bacteria must be rapidly separated from blood, a very difficult process considering that concentrations of bacteria are many orders of magnitude lower than ... -
