Fabrication of a molecularly imprinted monolithic column via the epitope approach for the selective capillary microextraction of neuropeptides in human plasma Vrije Universiteit Brussel
Metal-organic framework ZIF-8 for exceptional HCl removal from Hydrogen gas by reaction Vrije Universiteit Brussel
Smart protective coatings with self-sensing and active corrosion protection dual functionality from pH-sensitive calcium carbonate microcontainers Vrije Universiteit Brussel
Herein, we report the development of a self-sensing and active corrosion protection coating which incorporates pH-sensitive multilayer chitosan/alginate-covered CaCO3 microcontainers containing 1,10-phenanthrolin-5-amine (APhen). The microcontainers can respond to pH variation to release APhen which serves not only as a corrosion indicator but also as an inhibitor. An epoxy coating doped with 5 wt% microcontainers exhibited improved corrosion ...
Growth mechanism study of silver nanostructures in a limited volume Vrije Universiteit Brussel
Recently, high attention has been paid to template synthesis as a method for obtaining nanostructures with predetermined shapes and sizes. This is an obvious approach, in which the size and shape of the pores limit the geometry of the nanostructures formed inside them. As a result, nanostructures completely repeat the shape of the template pores. However, in some cases, the morphology of the resulting structures may differ from the shape of ...
Corrosion inhibition of AA6060 by silicate and phosphate in automotive organic additive technology coolants Vrije Universiteit Brussel
Coolant corrosion inhibitors are paramount for the durability of automotive heat exchangers. The novel generation of “hybrid coolants” consists of inorganic inhibitors added to an OAT (Organic Additive Technology) backbone. This investigation appraises the corrosion inhibition provided by OAT, phosphate and silicate (separately and combined) on AA6060 exposed to antifreeze coolant at 75 °C. The effects of hard water cations and temperature ...
Revisiting the surface characterization of plasma-modified polymers Vrije Universiteit Brussel
Many papers dealing with the surface analysis of plasma polymers or plasma-modified polymers report the use of X-ray photoelectron spectroscopy (XPS) to quantify the surface composition. However, most of the time, quantification is performed using software that includes an equation based on the assumption that the sample is homogeneous in composition. However, for plasma-treated samples, this is often not the case. The usual analysis of XPS ...
The Hot-Stamping Effect on the Corrosion Properties of the 22MnB5 Steel Coated with Hot-Dip Aluminum-Silicon Assessed by a Salt Spray Test and Raman Spectroscopy Vrije Universiteit Brussel
The effect of hot stamping on the corrosion properties of boron-manganese 22MnB5 steel coated with hot-dip aluminum-silicon was evaluated under severe conditions by a continuous salt spray test (SST). The corrosion mechanism changed from localized to generalized, as cathodic precipitates were not present after hot stamping. Intrinsic defects in press-hardened steel samples were the reason for severe damage in both metallic coating and steel ...
Operando odd random phase electrochemical impedance spectroscopy for in situ monitoring of the anodizing process Vrije Universiteit Brussel
Eruption frequency and magnitude in a geothermally active continental rift Vrije Universiteit Brussel
Many Quaternary silicic volcanoes in the Main Ethiopian Rift pose a potential risk due to the poorly known eruptive histories of the volcanoes in combination with a high population density. In this study we provide new constraints on the Late Pleistocene-Holocene eruptive history of the Bora-Baricha-Tullu Moye (BBTM) volcanic complex located in the central portion of the Main Ethiopian Rift (MER). BBTM constitutes three main silicic edifices ...
