    Ferroelectric Properties and Electrocaloric Effect in Dy2O3 Substitution on Lead-Free (Na0.5 Bi0.5)0.94 Ba0.06TiO3 Ceramic by Turki, O.

    Published 2023
    “…Higher stability of the ferroelectric (FE) phase was obtained at room temperature for the compositions y = 0.01, 0.02 and 0.05, with optimum values for y = 0.02 as remanent polarization Pr = 32µC/cm2, as well as piezoelectric coefficients d33 = 137 pC/N, kp = 0.27 and kt = 0.16, whereas a higher content of Dy (y = 0.08) induced a remarkable decrease of the ferroelectric and piezoelectric properties. …”

    Trends in fecal carriage of carbapenemase-producing Enterobacterales in children before and after the implementation of international travel restrictions in response to COVID-19 by Andrés, Pérez-López

    Published 2021
    “…Consequently, the number of arrivals in Qatar declined almost 95% during the rest of 2020 compared with the same period in 2019 [1]. Analysis of quarterly trends revealed a significant and sustained decrease in the rate of colonization after the implementation of travel restrictions (P < 0.01), while testing rates did not vary significantly (P = 0.6) (Fig. 1). …”

    Acidity's Impact on Yield, Morphological Structure, and Surface Functionalities of Polyaniline Synthesised via Oxidative Polymerisation by Ahmat, Dounia Ousmane

    Published 2023
    “…To answer the research objective, the medium acidity was manipulated using different concentrations of HCl (i.e., 0 M, 0.01 M, 0.1 M, 1M and 10M). The as-synthesised PANIs were then purified and characterised for their physicochemical properties. …”

    The Structure of the Free Volume in Poly(styrene-co-acrylonitrile) from Positron Lifetime and Pressure Volume Temperature (PVT) Experiments by Dlubek, Gunter

    Published 2004
    “…The mean hole volume, vh, varies in PS between 105 Å3 (27 °C) and 220 Å3 (190 °C), and shows a systematic decrease with increasing AN content, at Tg from 121 Å3 for PS to 102 (±2) Å3 for SAN50. …”

    Fabrication and characterization of flexible ruthenium oxide-loaded polyaniline/poly(vinyl alcohol) nanofibers by Chamakh, M.

    Published 2020
    “…The tests revealed the decrease of electrical resistivity and activation energy with increasing RuO2 concentration for the as-prepared samples, while the annealed samples showed lower activation energy values of ~0.1 eV with increasing the concentration of RuO2. …”

    Impact On Local Pearl Oyster Pinctada Radiata Exposed To Chronic Levels Of Chlorine by Alfaqih, Arwa Shaif

    Published 2019
    “…The experiment was run during 75 days at ExxonMobil Research Qatar with adult oysters (originally collected from AlWakra coastal waters) being exposed to two different concentration of chlorine (0.025 and 0.1 mg/l) and a control treatment. Our results suggested that exposure to chlorine had non-significant effects on the mortality, growth and physiology (respiration rate) of healthy oysters. …”
