Finally, the enzyme reactor could be applied in AChE inhibitors screening, which expanded its application capability. The proposed protocol not only paves a new way for fabrication of novel aptamer functionalized magnetic COF materials as enzyme reactors, but also indicates a broadened application of the integration of aptamer and its enzyme.

The extraction of vanadium from titanomagnetites and other sources
Vanadium does not form concentrated deposits like other metals such as copper, nickel or zinc. It is widely dispersed in the Earth's crust, with V 3+ replacing Fe 3+ or Al 3+ in a number of minerals. Vanadium as V 3+ can substitute for Fe 3+ in magnetite (Wenk and Bulakh, 2004); vanadium(III) and iron(III) ions have near identical ionic radii in octahedral sites of …

Comminution and classification technologies of iron ore
Hematite and magnetite, the two predominant iron ores, require different processing routes. High-grade hematite direct shipping ores generally only require crushing and screening to meet the size requirements of lump (typically between 6 and 30 mm) and fines (typically less than 6 mm) products. Low-grade hematite ores require additional ...

Exposure dating of detrital magnetite using 3He …
25 comparing th ese data to the known exposure age of 53.5 ka, we calibrate a magnetite 3He SLHL production rate of 116±13 at g-1 a-1. We suggest that the microCT screening approach can be used to improve the quality of cosmogenic 3He measurements of magnetite and other opaque mineral phases for exposure age and detrital studies.

Abstract. We test whether X-ray micro-computed tomography (microCT) imaging can be used as a tool for screening magnetite grains to improve the accuracy and precision of cosmogenic 3He exposure dating. We extracted detrital magnetite from a soil developed on a fanglomerate at Whitewater, California, which was offset by the Banning strand of the San Andreas Fault.
