Direct Reuse of Spent Nd-Fe-B Permanent Magnets.

Nd-Fe-B permanent magnets are vital for numerous key technologies in strategic sectors such as renewable energy production, e-mobility, defense, and aerospace. Accordingly, the demand for rare earth elements (REEs) enormously increases in parallel to a significant uncertainty in their supply. Thus, research and innovative studies are focus on the investigation of sustainable solutions to the problem and a closed-loop value chain.

Flow-Induced Vesicle Translocation through a Narrow Slit─Transit Time Scaling Relations.

The translocation of soft objects like transferosomes and vesicles through splenic interendothelial slits is a major factor in vesicular transdermal delivery system for enhanced drug permeation or disease progression and also plays a critical role in microfluidic devices used for separation purposes. Using extensive Molecular Dynamics simulations, we study the pressure-driven flow-induced translocation of a loaded vesicle through a narrow rectangular slit whereby the hydrodynamic interactions in the channel are taken into account by means of multiparticle collision dynamics (MPCD). Considering vesicles of different size , moving in a stream induced by a constant body force , we demonstrate that the transit time τ of the vesicle passing through a slit with half-width scales as τ ∝ , confirming earlier theoretical predictions.

Green Synthesis of Antimicrobial Silver Nanoparticles (AgNPs) from the Mucus of the Garden Snail .

The green synthesis of metal nanoparticles, mediated by extracts from various biological sources, leads to the formation of nanoparticles with unique characteristics and potential biomedical applications. In this study, a fraction of the mucus from the snail with MW > 20 kDa was used as a bioreducing and biostabilizing agent to obtain silver nanoparticles (AgNPs) in different pH media (pH 1.5, 3.

Green Synthesis of Antibacterial CuO Nanoparticles Based on the Synergy Between Snail Mucus and Ascorbic Acid.

Many biologically active compounds have been identified in the mucus of the garden snail , which are effective in the treatment of several diseases such as cancer, ulcers, wounds, etc. The incorporation of these compounds into the green synthesis of copper nanoparticles (CuONPs-Muc) was demonstrated in our previous study. Based on the synergistic effect of two reducing agents- snail mucus and ascorbic acid (AsA)-on CuSO.

Development of CuO Nanoparticles from the Mucus of Garden Snail as New Antimicrobial Agents.

Several biologically active compounds involved in the green synthesis of silver and gold nanoparticles have been isolated from snail mucus and characterized. This paper presents a successful method for the application of snail mucus from as a bioreducing agent of copper sulfate and as a biostabilizer of the copper oxide nanoparticles (CuONPs-Muc) obtained. The synthesis at room temperature and neutral pH yielded nanoparticles with a spherical shape and an average diameter of 150 nm.

Smart Complex Fluids Based on Two-Antennary Oligoglycines.

Antennary oligoglycines are synthetic products, obtained as a result of preliminary molecular design. Equal-length antennae are built of glycine residues joined through the C end to an oligoamine branching core with an amine group at the N terminus exposed outside. The results of systematic research on the properties of aqueous solutions containing two-antennary oligoglycine with four glycine portions are reported.
