Mathematical model of the catalytic effect of chromium(VI) on hypochlorite disproportionation in chlorate electrolysis
(Pennington N.J. : Electrochemical Society, 2018)
The effect of chromium(VI) on the kinetics of disproportionation of hypochlorous acid and hypochlorite was established in the solution for the electrolytic production of chlorate. The hexavalent chromium species Cr2O7 2-, ...
Nanosized hydroxyapatite and other calcium phosphates: Chemistry of formation and application as drug and gene delivery agents
(Journal of Biomedical Materials Research Part B: Applied Biomaterials, 2011)
The first part of this review looks at the fundamental properties of hydroxyapatite (HAP), the basic mineral constituent of mammalian hard tissues, including the physicochemical features that govern its formation by ...
The influence of thin benzoate-doped polyaniline coatings on corrosion protection of mild steel in different environments
(Progress in Organic Coatings, 2013)
The corrosion process of mild steel in the presence of benzoate-doped polyaniline coatings exposed to different environments (3% NaCl, atmosphere, and the Sahara sand) has been investigated. This system was also tested for ...
Integer Codes Correcting Spotty Byte Asymmetric Errors
(IEEE, 2016)
In short-range optical networks, channel errors occur due to energy losses. Upon transmission, they mostly manifest themselves as spotty byte asymmetric errors. In this letter, we present a class of codes that can correct ...
The influence of alkaline cations on the mechanism and kinetics of dehydration of polymeric phthalatocuprate(II) dihydrates
(Elsevier, 2017)
Thermal dehydration of two heterometallic complexes containing dianion of phthalic acid, pht, Na2[Cu(pht)2] · 2H2O, 1, and K2[Cu(pht)2] · 2H2O, 2, was investigated under non-isothermal conditions. Mechanism and kinetics ...
Mg/Cu co-substituted hydroxyapatite – Biocompatibility, mechanical properties and antimicrobial activity
(Elsevier, 2019)
The aim of this study was to improve the mechanical properties and to optimize antimicrobial activity of hydroxyapatite (HAP) by simultaneous doping with Mg and Cu ions in order to obtain material that would be able to ...
Humidity sensing potential of Fe2TiO5—pseudobrookite
(Springer US, 2018)
Bulk samples of pseudobrookite with an orthorhombic crystal structure were prepared by sintering a mixture of starting hematite and anatase nano powders in the weight ratio 60:40 at three different sintering temperatures ...
Does galvanic vestibular stimulation decrease spasticity in clinically complete spinal cord injury?
(Lippincott Williams and Wilkins, 2018)
The aim of this study was to determine changes in clinical and biomechanical measures of spasticity after administering galvanic vestibular stimulation in patients with a complete spinal cord injury (SCI). The spasticity ...
The influence of mechanical activation on the electrical properties of Ba0.77Sr0.23TiO3 ceramics
(Ceramics International, 2014)
Ferroelectric barium strontium titanate (Ba0.77Sr0.23TiO3), BST, was prepared by solid-state reactions using as the starting compounds powder of barium carbonate (BaCO3), strontium carbonate (SrCO3) and titanium dioxide ...
Insertion of lithium ion in anatase TiO2 nanotube arrays of different morphology
(Elsevier, 2017)
Anatase TiO2 nanotube arrays of different morphology were prepared by a two-step process: anodic oxidation at voltages 20–60 V and subsequent annealing at 400 °C. By amplifying anodization voltage the inner diameter of ...
