Controlled biodegradation of magnesium alloy in physiological environment by metal organic framework nanocomposite coatings. [PDF]
Sci Rep, 2021 Magnesium-based implants (MBIs) have recently attracted great attention in bone regeneration due to elastic modulus similar to bone. Nevertheless, the degradation rate and hydrogen release of MBIs in the body have to be tackled for practical applications.

Evaluation of the mulch films biodegradation in soil: a methodological review
Italian Journal of Agronomy, 2021 Plastic mulch films are widely used in agriculture, but most are not biodegradable in soil. Biodegradable mulch films are blends of different polymers whose composition-ratios vary notably from one product to another. Their degradation rates vary greatly

Antibacterial Activity of a Trace-Cu-Modified Mg Alloy in Simulated Intestinal Fluid [PDF]
Journal of Functional BiomaterialsMg alloys hold promise for biodegradable gastrointestinal implants, but most evaluations rely on simplified media like Hank’s solution, which lacks organic components and fails to replicate the acidic-to-alkaline transition of intestinal fluid, risking ...
