Heat has always moved silently between surfaces, indifferent to the wishes of engineers — but a team at CUNY's Advanced Science Research Center, working alongside Honeywell Aerospace, has found a way to quiet that exchange without reaching for metal. By designing pairs of ultrathin nonmetallic coatings that speak, in a sense, different thermal languages, they have reduced radiant heat transfer by more than 80 percent — a result published in Nature Communications that reframes the problem from individual surface performance to coordinated systemic design. The advance matters because metals, lon
