As compared with other candidate carbon sequestration technologies, mineral carbonation offers the unique advantage of permanent disposal via geologically stable and environmentally benign carbonates. The primary challenge is the development of an economically viable process. Enhancing feedstock carbonation reactivity is key. Heat activation dramatically enhances aqueous serpentine carbonation ...

Efficient use of highly dispersed metal oxides for lighting, energy conversion and catalysis requires knowledge about the impact of density and microstructure of the powders on the optical nanoparticle properties. For MgO nanocube powders we present a combined photoluminescence (PL) and electron paramagnetic resonance (EPR) approach which enables for samples of different aggregation states the ...

Since being discovered initially in mixed-cation systems, a method of forming end-member MgSO4 9H2O has been found. We have obtained powder diffraction data from protonated analogues (using X-rays) and deuterated analogues (using neutrons) of this compound over a range of temperatures and pressures. From these data we have determined the crystal structure, including all hydrogen positions, the ...

The vibrational spectrum of hydrogen atoms in magnesium hydride has been studied by means of inelasticneutron and Raman-scattering experiments between 12 and 295 K. After careful evaluation of multiple scattering and multiphonon contributions, we provide a vibrational frequency spectrum up to 180 meV and the mean-square displacement of hydrogen atoms. The inelastic light scattering spectra of M...

Entomopathogenic fungi are promising pest-control agents but their industrial applicability is limited by their thermosusceptibility. With an aim to increase the thermotolerance of Isaria fumosorosea SFP-198, moisture absorbents were added to dried conidial powder, and the relationship between its water potential and thermotolerance was investigated. Mycotized rice grains were dried at 10℃, 20℃...

Abstract The exploratory experiments of laser fusion welding with Sn powder and the automotive adhesive addition were conducted for DP590 dual-phase steel AZ31B magnesium alloy in an overlap steel-on-magnesium configuration. characteristics metal vapor/plasma analyzed by collecting analyzing plasma shape spectra. microstructure welded was characterized scanning electron microscopy (SEM), X-ray ...

To the Editor, Pica refers to an abnormal appetite for non-edible substances usually occurring in children with developmental disability or brain injury. However, it can also occur during adulthood, as it is associated with iron deficiency. Pica requires medical attention in case of severe eating behaviour that can be potentially harmful. Here we present a case of craving for Johnson's ® baby t...

The development of the MgB2 manufacturing process to increase current density is an important issue study. In this work, ceramics were manufactured by using solid-state technique. To study influence dry milling on formation and grain size, variations in ball powder weight ratio (BPR) sintering temperature used as control parameters. Magnesium boron with stoichiometric 2:1 was weighed milled for...

Synthetic magnesium silicate finds applications in adsorbents, catalysis, pharmaceuticals, foods, cosmetics, and oil industry. This study introduces a method for potential one-pot preparation of narrowly sized, spherical powders. After initial synthesis by precipitation from sulphate sodium metasilicate solutions, the precursor was ball-milled with two immiscible liquids, forming particle-loade...
