“One of the greatest metaphorical candle problems of the modern economy is cadmium plating,” he writes. “Cadmium has some unique physical properties that make it especially useful as a plating to protect precision-machined parts from corrosion. Once a machined part is expertly coated in cadmium, that part resists corrosion, is highly solderable and compatible with other metals, and requires little lubrication.”
However, he adds, “cadmium is also an extremely toxic compound, comparable to nuclear weapons in its capacity to poison people and render the environment uninhabitable. Over the past decade, numerous attempts by federal regulators to remove hazardous materials from the environment have targeted cadmium. Executive orders regulating its use have been enacted and revoked, and the Environmental Protection Agency and the Occupational Safety and Health Administration monitor its toxic and carcinogenic impacts on people, water, and soil.”
Ionic Liquid [BMPy]Br as an Effective Additive During Zinc Electrodeposition from an Aqueous Sulfate Bath
The effects of a new ionic liquid additive 1-butyl-3-methylpyridinium bromide [BMPy]Br on the electrodeposition of zinc on steel substrates from acidic sulfate solution was investigated by employing potentiodynamic polarization and cyclic voltammetry techniques complemented with XRD and SEM measurements.
Andreas Osterwalder calls his office a museum: what looks like a collection of small machines are 3D printed and partially electroplated parts that the scientist has been creating for his experiments.
Layton Technologies designed a custom solvent cleaning system to remove wax from 3D-printed parts, replacing an inefficient manual process.
