As cities face growing risks from vehicle-borne threats, blasts, and seismic shocks, one thing is clear: the future of urban protection won’t look like thick concrete walls or unsightly barriers. Enter metal foam armor—a new class of material that looks like metal, acts like a sponge, and absorbs impact forces that would shatter traditional materials. […]| theconstructor.org
Acoustic metals are redefining how we design our cities—turning buildings and public spaces into active sound filters that can cut noise pollution without sacrificing aesthetics or structural integrity. Instead of relying on foam panels or fragile baffles, this innovation uses precision-engineered alloys embedded with microscopic chambers, tuned perforations, and sound-cancelling geometries. The result? Materials that […]| theconstructor.org
