A review of advances in the preparation and application of polyaniline based thermoset blends and composites
( Springer , 2020 , Article Review)For several decades, forming blend and composite of polyaniline (PANI) with insulating polymers has been a widely studied research area because of the potential applications of such blends, which have a unique combination ... -
Capacitive type humidity sensor based on PANI decorated Cu-ZnS porous microspheres
( Elsevier , 2020 , Article)Porous microstructure materials are considered good candidates for the development of highly sensitive and fast humidity sensors. In this regard, we prepared polyaniline (PANI) decorated Cu-ZnS porous microsphere structures ... -
Comparative Study on Gas-Sensing Properties of 2D (MoS2, WS2)/PANI Nanocomposites-Based Sensor
( MDPI , 2022 , Article)NH3 is a highly harmful gas; when inhaled at levels that are too high for comfort, it is very dangerous to human health. One of the challenging tasks in research is developing ammonia sensors that operate at room temperature. ... -
Covid-19 inspired a stem-based virtual learning model for middle schools—a case study of Qatar
( MDPI , 2021 , Article)An unprecedented turn in educational pedagogies due to the COVID-19 pandemic has significantly affected the students’ learning process worldwide. This article describes developing a STEM-based online course during the ... -
Cultivating STEM Interest in High School Students through Computer-assisted COVID-19 Pandemic Awareness Course
( IIKII , 2022 , Article)Due to the COVID-19 pandemic, students were sidetracked by the shift in the educational process, primarily in the field of STEM (science, technology, engineering, mathematics) education. Teachers were also besieged to find ... -
A distinctive method of online interactive learning in stem education
( MDPI , 2021 , Article)A breakthrough that has occurred in recent years is the emergence of the COVID-19 pandemic. It has affected various sectors of society, including the educational sector. It has prevented students from performing group-oriented ... -
Flexible piezoelectric nanogenerator based on [P(VDF-HFP)]/ PANI-ZnS electrospun nanofibers for electrical energy harvesting
( Springer , 2021 , Article)Abstract: Over the past decade, piezoelectric nanogenerator have attracted much attention to harvest mechanical energy from abundant resources in nature. Here, the ZnS microspheres is prepared by hydrothermal method and ... -
Long-Term Stability Analysis of 3D and 2D/3D Hybrid Perovskite Solar Cells Using Electrochemical Impedance Spectroscopy
( MDPI , 2020 , Article)Despite the remarkable progress in perovskite solar cells (PSCs), their instability and rapid degradation over time still restrict their commercialization. A 2D capping layer has been proved to overcome the stability issues; ... -
MAPbI3 Microrods-Based Photo Resistor Switches: Fabrication and Electrical Characterization
( MDPI , 2021 , Article)The current work proposed the application of methylammonium lead iodide (MAPbI3 ) perovskite microrods toward photo resistor switches. A metal-semiconductor-metal (MSM) configu-ration with a structure of silver-MAPbI3 ... -
Polyolefin-Based Smart Self-Healing Composite Coatings Modified with Calcium Carbonate and Sodium Alginate.
( MDPI , 2024 , Article)Corrosion-related damage incurs significant capital costs in many industries. In this study, an anti-corrosive pigment was synthesized by modifying calcium carbonate with sodium alginate (SA), and smart self-healing coatings ... -
The Prominent Roles of Undergraduate Mentors in an Online Near-Peer Mentoring Model
( MDPI , 2023 , Article)This study exemplifies a STEM-based online near-peer mentoring approach, incorporating 56 students (high and middle school mentees) and 16 secondary undergraduates (UG) mentors. The various constructive roles of UG mentors ... -
A STEM model to engage students in sustainable science education through sports: A case study in Qatar
( MDPI , 2021 , Article)Sports has the potential to integrate with different scientific subjects, including materials science and engineering, making it an ideal approach to enhance the students’ affinity toward sustainable education in science, ... -
A tailored innovative model of “research internship” aimed at strengthening research competencies in STEM undergraduates
( Emerald Publishing Limited , 2024 , Article)Purpose: Research internships are integral components of undergraduate programs that nurture students' skill sets. However, the current trend of these internships adopting a direct apprenticeship model, often termed ...
