A cool advance in thermoelectric conversion

2020/12/14A temperature gradient, or difference, within a material such as a metal or semiconductor can, through a phenomenon known as the Seebeck effect, give rise to an electrical voltage that drives a current. For many materials, the thermoelectric effect is too low to be useful, explains NSE Research Scientist Fei Han.

Polylactic acid

Polylactic acid, or polylactide (PLA) is a thermoplastic polyester with backbone formula (C 3H 4O 2) n or [–C(CH 3)HC(=O)O–] n, formally obtained by condensation of lactic acid C(CH 3)(OH)HCOOH with loss of water (hence its name). It can also be prepared by ring-opening polymerization of lactide [–C(CH 3)HC(=O)O–] 2, the cyclic dimer

Bioinspired improvement of laminated glass

Glass has a distinctive set of optical, thermal, mechanical, chemical, and electrical properties that are useful in many applications. Yet, the inherent brittleness of glass can limit its use in load-bearing applications for which structural failure has serious consequences (for example, large public structures). Preexisting surface flaws can propagate when combined mechanical and
