A chemistry team at the University of Waterloo, Canada, has achieved what may be a major breakthrough in battery technology. Led by Chemistry Professor Linda Nazar, the team discovered that the performance of a lithium-sulfur battery can be boosted dramatically by using a nanosheet of manganese dioxide. The increase has the potential to propel an […]

S.H. Bell’s Manganese Dust-Control Plan OK’d by City
Chicago public health officials have signed off on a Southeast Side company’s updated plan to cut emissions of brain-damaging manganese dust that regulators say pose a health risk to nearby residents. At its storage terminal along the Calumet River, S.H. Bell Co. has agreed to “a number of aggressive proactive mitigation measures,” according to a […]
What are manganese ore fines and how are they sintered?
Fines are the fine particles of manganese ore created when crushing manganese rocks. The fines are heated to sinter them (make them stick together, or become “agglomerated”). “The mines produce a lot of fines,” Hockaday explained. “But they can’t sell them, as furnaces won’t buy materials that are too fine.” So the mines separate out […]
Riding the battery material boat with manganese
The price action on battery metals has reached near-ludicrous levels this year; the global expectation of a new world in which all private vehicles are electric is becoming ever-more realised, and the cost of the associated materials is climbing rapidly. But not in all cases. Lithium and cobalt may have bust through the top of […]
Manganese-based MRI contrast agent may be safer alternative to gadolinium-based agents
Imaging compound developed by Mass. General team produces comparable image enhancement to the standard of care with rapid clearance, less likelihood of toxicity. A team of Massachusetts General Hospital (MGH) researchers has developed a potential alternative to gadolinium-based contrast agents (GBCAs) for magnetic resonance imaging (MRI). In their report that has been published online in Radiology, […]
Manganese dioxide shows potential in micromotors Date:
Manganese dioxide could make the preparation of micromotors increasingly cost-effective, opening up new avenues for their use, according to a new study from the University of Eastern Finland. Synthetic micromotors are tiny particles with dimensions less than the diameter of a human hair. Micromotors can undergo an autonomous motion in liquid environments, which can be […]
