Corrosion Inhibition of Al–alloy in 3.5% NaCl Solution by a Natural Inhibitor: An Electrochemical and Surface Study
(ESG, 2014)Root extract of Copt is chinensis (CCR) was used and its inhibition efficiency on corrosion of Al alloy in 3.5 wt.% NaCl was investigated through surface morphology and electrochemical techniques. The Nyquist ... -
Corrosion Inhibition of Carbon Steel in 1M HCI Solution by 2–amino–1–methylbenzene (2–methylaniline)
(ESG, 2014)The inhibition effect of 2-amino-1-methylbenzene (AMB) on the corrosion of carbon steel in 0.5 M H₂SO₄ was studied by weight loss, electrochemical impedance spectroscopy (EIS) techniques and potentiodynamic ... -
Corrosion mechanism of steels in MDEA solution and material selection of the Desulfurizing equipment
(ESG, 2017)In the present study, the corrosion properties of three steel were evaluated in 45 wt.% Methyldiethanolamine (MDEA) solution, saturated to the hydrogen sulfide (H2S) and carbon dioxide (CO2) as in the oilfields. Corrosion ... -
Dendrimers: a new class of corrosion inhibitors for mild steel in 1 M HCl: experimental and quantum chemical studies
(Elsevier, 2016)The inhibition properties of two ammonia cored dendrimers have been investigated for mild steel corrosion in 1 M hydrochloric acid solution using chemical, electrochemical, surface and quantum chemical calculation methods. ... -
Macrocyclic inhibitor for corrosion of N80 steel in 3.5% NaCl solution saturated with CO2
(Elsevier, 2016)The inhibition of the corrosion of N80 steel in 3.5 wt.% NaCl solution saturated with CO2 by the 1,2,4,7,9,10-hexaazacyclo-pentadeca-10,15-dien-3,5,6,8-tetraone (HPT) has been studied using Fourier transform infrared ... -
Opacities for photon splitting and pair creation in neutron star magnetospheres
(Oxford Univ Press, 2019)Over the last four decades, persistent and flaring emission of magnetars observed by various telescopes has provided us with a suite of light curves and spectra in soft and hard X-rays, with no emission yet detected above ... -
Polarization signatures of relativistic magnetohydrodynamic shocks in the blazar emission region. I. Force-free helical magnetic fields
(IOP, 2016)The optical radiation and polarization signatures in blazars are known to be highly variable during flaring activities. It is frequently argued that shocks are the main driver of the flaring events. However, the spectral ... -
A polarized fast radio burst at low Galactic latitude
(Oxford Univ Press, 2017)We report on the discovery of a new fast radio burst (FRB), FRB 150215, with the Parkes radio telescope on 2015 February 15. The burst was detected in real time with a dispersion measure (DM) of 1105.6 ± 0.8 pc cm−3, a ... -
Progress in multi-wavelength and multi-messenger observations of blazars and theoretical challenges
(MDPI, 2019)This review provides an overview of recent advances in multi-wavelength and multi-messenger observations of blazars, the current status of theoretical models for blazar emission, and prospects for future facilities. The ... -
Radiation and polarization signatures of the 3D multizone time-dependent hadronic blazar model
(IOP Publishing, 2016)We present a newly developed time-dependent three-dimensional multizone hadronic blazar emission model. By coupling a Fokker–Planck-based lepto-hadronic particle evolution code, 3DHad, with a polarization-dependent radiation ...
