A study on stability of active layer of polymer solar cells: effect of UV–visible light with different conditions
( Springer Verlag , 2019 , Article)The objective of this study is to investigate the stability of the active layer of polymer solar cells from the effect of UV–visible light irradiation using different conditions with respect to time. The active layers were ... -
Contributions of Fourier transform infrared spectroscopy in microplastic pollution research: A review
( Taylor and Francis , 2020 , Article)© 2020 Taylor & Francis Group, LLC. Fourier transform infrared (FTIR) spectroscopy has been extensively used in microplastic (MP) pollution research since 2004. The aim of this review is to discuss and highlight the ... -
COVID-19 personal protection equipment (PPE): A potential source of microplastic pollution in the State of Qatar
( Qatar University Press , 2020 , Poster)Coronavirus disease 2019 (COVID-19) has become a global pandemic. The personal protection equipment (PPE), especially medical face masks and N95 filtering face piece respirators (FFRs) are typically worn by people at ... -
Design of ophthalmic micelles loaded with diclofenac sodium: effect of chitosan and temperature on the block-copolymer micellization behaviour
( Springer , 2022 , Article)Diclofenac sodium 0.1% is a commonly used NSAID with well-documented clinical efficacy in reducing postoperative inflammation; however, its corneal tolerability and ophthalmic tissue bioavailability require further ... -
Eeonomer 200F: A High-Performance Nanofiller for Polymer Reinforcement-Investigation of the Structure, Morphology and Dielectric Properties of Polyvinyl Alcohol/Eeonomer-200F Nanocomposites for Embedded Capacitor Applications
( Springer New York LLC , 2017 , Article)In the present study, Eeonomer 200F® was used as a high-performance nanofiller to prepare polyvinyl alcohol (PVA)-based nanocomposite films using a simple and eco-friendly solution casting technique. The prepared PVA/Eeonomer ... -
FTIR Spectroscopy to Reveal Lipid and Protein Changes Induced on Sperm by Capacitation: Bases for an Improvement of Sample Selection in ART.
(2020 , Article)Although being a crucial step for Assisted Reproduction Technologies (ART) success, to date sperm selection is based only on morphology, motility and concentration characteristics. Considering the many possible alterations, ... -
Insights into the degradation mechanism of PET and PP under marine conditions using FTIR
( Elsevier , 2023 , Article)Plastics possess diverse functional properties that have made them extremely desirable. However, due to poor waste management practices, large quantities eventually end up in the oceans where their degradation begins. ... -
Investigation of the effect of PD-L1 blockade on triple negative breast cancer cells using fourier transform infrared spectroscopy
( MDPI AG , 2019 , Article)Interactions between programmed death-1 (PD-1) with its ligand PD-L1 on tumor cells can antagonize T cell responses. Inhibiting these interactions using immune checkpoint inhibitors has shown promise in cancer immunotherapy. ... -
Multivariate analysis for FTIR in understanding treatment of used cooking oil using activated carbon prepared from olive stone
( Public Library of Science , 2020 , Article)In this study, activated carbons prepared from the green and black olive stone (green OSAC and black OSAC) were used as adsorbents to investigate their removal efficiencies for oxidation products and polar compounds from ... -
Prevalence of microplastics in the marine waters of Qatar
( Hamad bin Khalifa University Press (HBKU Press) , 2016 , Conference Paper)The issue of plastic pollution in the marine environment is of increasing global concern. As plastics typically have an intrinsic durability, water insolubility and slow degradation rates, debris has now become both ... -
Prevalence of microplastics in the marine waters of Qatar
