Rapid reduction of N-nitrosamine disinfection byproducts in …
There is a need for new technologies to rapidly and economically treat water contaminated with N-nitrosodimethylamine (NDMA) and related compounds because of their high toxicity and recent detection in drinking water sources as a consequence of industrial releases and chlorine disinfection of wastewater effluent Treatment of N-nitrosamines with H 2 2
Cobalt Mining: The Dark Side of the Energy Transition
At the most basic level, EV batteries are charged and discharged through the flow of lithium ions between the anode (positively charged) and the cathode (negatively charged).The cathodes contain nickel, and play a role in delivering high energy density, which allows the vehicle to travel further.

Lead, Zinc and Other Byproduct Metals | SpringerLink
Lead and zinc (and a number of other metals, discussed in this chapter) are almost invariably found in copper ores (in trace amounts, to be sure) and conversely. Most lead mines also produce zinc, and conversely. Molybdenum, nickel and cobalt are also commonly found with copper, though copper is generally a byproduct of these metals …
Rapid Reduction of N-Nitrosamine Disinfection Byproducts …
Treatment of N-nitrosamines with H2 in conjunction with a high surface area porous nickel material, a model nonprecious metal catalyst, has been evaluated. Experiments show that NDMA is reduced rapidly and catalytically to dimethylamine and N2 (e.g., t1/2 = 1.5 min for 500 mg/L catalyst and PH2 = 1 atm), and kinetic trends are consistent with a ...
Stress in Electroless Nickel Coatings | Products Finishing
Electroless nickel coatings are widely used because of their uniform thickness, corrosion resistance, hardness, wear resistance and magnetic response.
