Corrosion Inhibition of Mild Steel in HCl Medium by S-benzyl-O,O'-bis(2-naphthyl)dithiophosphate with Ultra-long Lifespan

Publication date: Available online 11 July 2018Source: Results in PhysicsAuthor(s): Chengduan Wang, Chuan Lai, Bin Xie, Xiaogang Guo, Dong Fu, Bin Li, Shasha ZhuAbstractHerein, the target compound of S-benzyl-O,O'-bis(2-naphthyl)dithiophosphate (SBOB) as corrosion inhibitor with ultra-long lifespan was successfully synthesized and characterized by elemental analysis, single crystal X-ray diffraction and spectroscopy involving FT-IR, 1H, 13C and 31P NMR. Meanwhile, the inhibition performance and mechanism of SBOB for mild steel (MS) in HCl medium were combined to investigate by weight loss, potentiodynamic polarization, electrochemical impedance spectroscopy, scanning electron microscopy and quantum chemical calculation. The potentiodynamic polarization results indicate that SBOB is a mixed-type inhibitor. All experimental results are in good agreement and reveal that the corrosion inhibition increases with the concentration of SBOB. Weight loss results indicate that the inhibition efficiency decreases with HCl concentration and temperature increasing, but the corrosion inhibition performance of SBOB keeps almost unchanged after ultra-long storage time due to the formation of inhibitor film by the physisorption and chemisorption of SBOB on MS surface.

AbstractComplex Regional Pain Syndrome type 1 (CRPS-1) is a disabling painful disease whose hallmark is pain disproportionate to inciting event. CRPS is also characterized by symptoms and signs, such as vasomotor, sudomotor, trophic and motor changes. Therapeutic approach of CRPS-1 still remains a challenge for clinicians treating a disease with potential heavy consequences on patient prognosis. In the past years, the treatment with bisphosphonates (BPs) has gained some success as confirmed by the results of a number of meta-analyses. The aim of this paper is to point out the pivotal role of bone in CRPS pathogenesis. The ...

Conclusions Our study demonstrates that with increasing BMI there is a greater distance between the skin surface and the muscle fascia of muscles that are targeted for injection in standard chronic migraine botulinum toxin injection protocols. Because of this, patient body habitus may be an important factor in injection technique.
