Chordal replacement with expanded tetrafluoroethylene (ePTFE) sutures is commonly used to correct leaflet prolapse in degenerative mitral and tricuspid valve disease. The concept of “respect rather than resect” the posterior was introduced by Perier colleagues1Perier P. Hohenberger W.

The electrochemical nitrogen reduction reaction (NRR) is a promising alternative to the current greenhouse gas emission intensive process produce ammonia (NH 3 ) from (N 2 ). However, finding an electrocatalyst that promotes NRR over competing hydrogen evolution (HER) has proven be difficult. This difficulty could potentially addressed by accelerating development for orders of magnitude using h...
