People may become sensitized to certain metals by skin contact, usually by wearing or holding consumer products (including non-metal products, like textiles and leather treated with metals), or sometimes after exposure at work. Contact with damaged skin makes sensitization more likely. Medical implants may also cause allergic reactions.
Liquid metal embrittlement (LME) is the embrittlement caused by liquid metals. Metal-induced embrittlement (MIE) is the embrittlement caused by diffusion of atoms of metal, either solid or liquid, into the material. For example, cadmium coating on high-strength steel, which was originally done to prevent corrosion.
The brittle fracture theory of Stoloff and Johnson, [14] Westwood and Kamdar [15] proposed that the adsorption of the liquid metal atoms at the crack tip weakens inter-atomic bonds and propagates the crack. Gordon [16] postulated a model based on diffusion-penetration of liquid metal atoms to nucleate cracks which, under stress, grow to cause ...

Improper use of aluminium in contact with stainless steel had caused rapid corrosion in the presence of salt water. [13] The electrochemical potential difference between stainless steel and aluminium is in the range of 0.5 to 1.0 V, depending on the exact alloys involved, and can cause considerable corrosion within months under unfavorable ...
How to handle it: Look for peptides in your skin-care products (scan the ingredient label). “They’re the building blocks of certain proteins that drive an increase in collagen,” says Dr. Levin.
The compound becomes progressively sensitive as it is aggregated, even in small amounts; the touch of a falling feather, the impact of a single water droplet, or a small static discharge are all capable of explosively detonating an unconfined pile of silver fulminate no larger than a dime and no heavier than a few milligrams. Aggregating larger ...
