Mathematical puzzle from 1904 takes physical form in gold-studded helium droplets in ssalimpour

Researchers used spark plasma sintering technology to deposit silver, zinc, and copper metal oxide nanoparticles directly onto thermoplastic starch/carboxymethyl cellulose films, then measured changes in mechanical strength, wettability, morphology, color, and thermal behavior. The treatment increased tensile strength and reduced surface wettability, with the results varying by metal and reflecting interactions between the deposited particles and polymer functional groups. 10/27/2026
