Self-Assembly of a Dipeptide with a Reduced Amount of Copper into Antifungal and Antibacterial Particles.

With the growing concern over the environmental impact and health risks associated with conventional pesticides, there is a great need for developing safer and more sustainable alternatives. This study demonstrates the self-assembly of antimicrobial and antifungal spherical particles by a dipeptide utilizing a reduced amount of copper salt compared to the commonly employed formulation. The particles can be sprayed on a surface and form an antimicrobial coating.

Fabrication of antimicrobial polymeric films by compression molding of peptide assemblies and polyethylene.

This paper presents compression molding of peptide assemblies with low-density polyethylene (LDPE) for the robust production of antimicrobial polymeric films. These films show a significant reduction of colony-forming units and plaque-forming units. Moreover, they significantly inhibited the growth of three different fungi.

Effect of the membrane exclusion mechanism on phosphate scaling during synthetic effluent desalination.

Calcium phosphate scaling is one of the main limitations in effluent desalination using membranes. This may be overcome by tailoring membranes with lower rejection of the scalant ions. In this study, we systematically examined the use of negatively and positively charged membranes, rejecting ions mainly based on Donnan exclusion, as a low-scaling alternative to dielectric-exclusion-dominated polyamide NF membranes for effluent desalination.
