Nickel (Ni) is an economically important metal characterized by its mechanical strength and anticorrosion properties. With the increasing industrial demand for Ni depleting accessible primary ores, sustainable technologies are required recovery of this from alternative resources. In study, adsorption using chitosan was investigated as a technique to recover sulfate (SO42−) calcium (Ca) rich sec...

LiMnO2 is one of only a few ternary oxides which are known to form in the orthorhombic Pmmn structure. The layered α-NaFeO2 structure, favored for application as a Li-insertion electrode, is found in many other alkali transition metal oxides. We find that the the strong antiferromagnetic interactions between Mn+3 ions contribute to the stabilization of the orthorhombic structure. Using first-pr...

Background: Pediatric-onset multiple sclerosis (MS) is associated with a high rate of disease activity. However, only single DMT – fingolimod has been approved by Health Canada for children, in 2018. In this study, we describe trends the treatment pediatric-onset MS Alberta. Methods: We performed retrospective review Alberta administrative health databases, identifying cases under 19 years age ...

Sulfate (SO42-) and nitrate (NO3-) are the main secondary inorganic components in atmospheric particulates. It is of great significance to understand formation evolution air pollution process pollution. In this study, samples PM10 were collected Jinhua City eastern China from December 2019 January 2020 June August 2020, also analyzed influence different meteorological conditions gaseous polluta...

Over three million hectares of salt-affected soils characterized with high salinity and sodicity caused serious land degradation in Songnen Plain, northeast China. Soil salinity–sodicity heterogeneous distribution under microtopography is usually influenced by several environmental factors. The side direction movement of soil water driven by water from depression is the key factor that aggravat...

The microbial community response to petroleum seepage was investigated in a whole round sediment core (16 cm length) collected nearby natural hydrocarbon seepage structures in the Caspian Sea, using a newly developed Sediment-Oil-Flow-Through (SOFT) system. Distinct redox zones established and migrated vertically in the core during the 190 days-long simulated petroleum seepage. Methanogenic pet...

A combination of Fourier transform infrared and phase transition measurements as well as molecular computer simulations, and thermodynamic modeling were performed to probe the mechanisms by which guanidinium (Gnd+) salts influence the stability of the collapsed versus uncollapsed state of an elastin-like polypeptide (ELP), an uncharged thermoresponsive polymer. We found that the cation's action...

Abstract The full-heavy tetraquarks $$cc{\bar{c}}{\bar{b}}$$ c ¯ b and $$bb{\bar{b}}{\bar{c}}$$ are systematically investigated within a quark model. meson–meson structure, diquark–antidiquark structure K-structure considered in...
