The objective of the present work was to prepare hybrid epoxy composites with improved mechanical and thermal properties. The simultaneous use of two different modifiers in an epoxy resin was motivated by the expected occurrence of synergistic effects on the performance properties of the matrix. Such a hybrid composite can be used in more severe conditions and/or in broader application areas.

- The study examined how thermal aging, UV exposure, and stress softening impact rubber modified with two types of nanoclays, Cloisite Na and Cloisite 20A, by measuring properties like tensile strength and strain at break before and after aging.
- Results indicated that both tensile strength and strain at break decreased by about 50% after one week of aging, attributed to the breaking of chemical bonds between the rubber and nanoparticles.
- Additionally, while thermal aging increased the modulus of elasticity for different rubber samples, only the unmodified rubber showed a significant decrease in shape retention; overall, nanocomposite properties varied differently under aging and UV conditions.*
Oxidative phosphorylation is an essential metabolic process for cancer proliferation and therapy resistance. The ClpXP complex maintains mitochondrial proteostasis by degrading misfolded proteins. Madera Therapeutics has developed a class of highly potent and selective small-molecule activators (TR compounds) of the ClpXP component caseinolytic peptidase proteolytic subunit (ClpP).

If not properly managed, this waste can contribute to environmental pollution and pose a threat to human and animal welfare. An interesting and more sustainable alternative is therefore the bioconversion of keratin using microorganisms and their enzymes.
