Room-Temperature Stabilization of a Hidden FCC–BCC Phase in Silver Nanoparticle Superlattices

Researchers from Brown University and the University of Michigan used shape-tuned silver nanoparticles called 'mecons' to self-assemble into superlattices that stabilize the intermediate structures predicted by the Nishiyama-Wassermann pathway for the FCC-to-BCC transition. The resulting material locks in a long-theorized phase at room temperature and exhibits deep-strong light-matter coupling, offering a potential platform for quantum information technologies and quantum computing applications.

Tea extracts boost silver nanoparticles' antimicrobial power against pathogens

Researchers at the Institute of Physical Chemistry of the Polish Academy of Sciences have developed green tea-silver nanoparticles that exhibit powerful antimicrobial activity against bacteria and yeast. The hybrid nanoparticles, synthesized using tea extracts as a capping agent, showed higher antibacterial and antifungal properties compared to silver nanoparticles alone. The nanoparticles were effective against ESKAPE bacteria and problematic yeast pathogens, reducing the number of bacterial and fungal cells. The combination of tea extracts and silver nanoparticles could potentially be used as an alternative to antibiotics in combating infections, with lower dosages required. The researchers aim to further explore the applications of these nanoparticles in agriculture and biomedical fields.

"Silver Nanoparticles Revolutionize Thermoelectric Power Generation"

An international team of scientists has developed a new approach to constructing thermoelectric modules using silver nanoparticles to connect the modules' electrode and metallization layers. The use of silver nanoparticles was tested for stability in modules built of three different state-of-the-art thermoelectric materials, designed to operate across a wide range of temperatures. The researchers found that silver nanoparticles have a much lower melting point than bulk silver, making them an ideal connective material for thermoelectric modules. This development should accelerate the development of advanced modules for power generation and other uses.
