Article Synopsis
- Researchers developed a two-step method to grow high-quality MoS nanoflakes using low-pressure chemical vapor deposition on sapphire substrates.
- The process involved synthesizing a MoS layer and then re-evaporating it at a higher temperature to create mono- or few-layer nanoflakes, confirmed by atomic force microscopy and transmission electron microscopy.
- The study highlighted the unique properties of MoS nanoflakes, including their response to polarized light, suggesting potential uses in advanced photodetectors.
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.
View Article and Find Full Text PDFAntennary 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.
