Chiral Cobaltabis(dicarbollide) Catalysts Prepared Using a Silica Helical Nanoplatform for the Enantioselective Photooxidation of Aromatic Secondary Alcohols

Chemistry – A European Journal, Accepted Article.
Cobaltabis(dicarbollide) ([Co(C2B9H11)2]‐) named COSAN has been widely explored in a variety of fields. While COSAN have recently been investigated in catalysis, their chiral counterparts have, to our knowledge, never been investigated in asymmetric catalysis.

Development of a Porous Solid Model for the Direct Reduction of Iron Ore Pellets

steel research international, Volume 93, Issue 12, December 2022., 2022
Computational fluid dynamics simulations can accurately determine the flow field of the reducing agent in the direct reduction of iron ore pellets. The external transport limitations are significant in the early stage of the reduction. The exact boundary conditions can be extracted from the flow field and later be used to derive very accurate kinetic ...

Effects of extracted-vanadium residue and MgO on the basic sintering characteristics of high-chromium vanadium–titanium magnetite

Journal of Materials Research and Technology, 2022
Extracted-vanadium residue (EVR), formed during the smelting and extraction of High-chromium vanadium-titanium magnetite (HCVTM), should be used cyclically, and its use as a sintering material to prepare sinters for blast-furnace smelting is a viable ...

Review of recent advances in the design, synthesis, and modification of biochar for remediation of heavy metal pollution in water

The Canadian Journal of Chemical Engineering, EarlyView.
Research frontiers in using biochar for heavy metal remediation. Abstract Heavy metal contamination of water has long been a serious environmental issue. Biochar and biochar‐based composites are emerging as effective and sustainable solutions for heavy metal removal due to their strong adsorption abilities and environmentally friendly nature.

Optimization of feed blends to enhance the roasting performance of pellets made from Western Australian ultrafine magnetite concentrate

工程科学学报, 2017
The conducted roasting tests were studied which pellets were made from blends of Western Australia ultrafine (WAU) magnetite concentrate and domestic magnetite concentrate or Brazilian hematite concentrate. The results show that the pellets made from 100%
