The Role of Ultra‐Thin Passive Films and Organic Adsorbates on Aluminum Chips for a Friction‐Induced Solid‐State Recycling Process

Advanced Engineering Materials, EarlyView.
Despite benefits to storage stability and handleability of aluminum scrap, octadecyl phosphonic acid (ODPA) SAMs reduce the tensile strength of wires produced using friction‐induced recycling. Etching and methyl diphosphonic acid (MDPA) coatings, however, have little effect.

The influences of chloride ion transmission on cracking and chemical corrosion resistance of PHC pipe piles

Chemical Engineering Transactions, 2018
High-performance concrete (HPC) is crack sensitive. The emergence of cracks reduces the durability of concrete. In the marine environment, HPC tubular piles act on the foundation with water pressure and are more susceptible to chloride ion erosion.
